Answer:

x + 10 = x² + 2x + 1

Step-by-step explanation:

[tex]\sqrt{x + 10}[/tex] - 1 = x

x + 1 = [tex]\sqrt{x + 10}[/tex]

Squaring both sides gives;

(x + 1)² = ([tex]\sqrt{x + 10}[/tex])²

x + 10 = x² + 2x + 1

Answer:

option B

Step-by-step explanation:

the given equation is,

[tex]\sqrt{x+10}-1 =x[/tex].................................(1)

adding  both side by 1 in equation (1)

[tex]\sqrt{x+10}= x + 1[/tex]

squaring both side              

x + 10 = ( x + 1 )²                

we know,

( a + b )²  = a² + b² + 2 a b

x + 10 = x² + 2 x + 1

hence, the correct answer is option B.

The answer is:

The value of Tan(x) is:

[tex]\frac{7}{24}[/tex]

Since we want to know the value of Tan(x), we need to use the following formula:

[tex]Tan(x)=\frac{Opposite}{Adjacent(XZ)}[/tex]

We already know the opposite side, but we need to find the value of the distance "XZ",so, we can calculate it using the Pythagorean Theorem since it's a right triangle.

Let be:

[tex]a=25\\b=7[/tex]

Then, finding "XZ" we have:

[tex]a^{2}=b^{2}+c^{2}\\ \\25^{2}=7^{2}+c^{2} \\\\c^{2}=625-49\\\\c=\sqrt{576}=24[/tex]

Now, finding the value of Tan(x), we have:

[tex]Tan(x)=\frac{opposite}{adjacent}\\\\Tan(x)=\frac{7}{24}[/tex]

Hence, we have that the value of Tan(x) is:

[tex]\frac{7}{24}[/tex]

Have a nice day!

Answer:

Tan X = 7/24

Step-by-step explanation:

From the figure we can see a right angled triangle XYZ.

XY = 25 and YZ = 7

To find value of XZ

XZ² = XY² - YZ²

 = 25² - 7²

 = 625 - 49

 = 576

XZ = √576 = 24

To find the value of X

Tan X = YZ/XZ

 = 7/24

Answer: cross section = 25π in²

Step-by-step explanation:

Cylinder volume is the product of the cross section by height.

Then cross section = cylinder volume/height = 200 π in³/8in = 25π in²

Answer: 25π in²

[tex]\textit{\textbf{Spymore}}[/tex]

The area of the cross-section of the cylinder is 25π in² square inches.

The volume V of a cylinder is given by the formula:

[tex]\[ V = \pi r^2 h \][/tex]

Where:

- r is the radius of the cylinder's base

- h is the height of the cylinder

Given that the volume of the cylinder is [tex]\( 200\pi \)[/tex] cubic inches and the height h is 8 inches, we can solve for the radius r:

[tex]\[ 200\pi = \pi r^2 \times 8 \][/tex]

[tex]\[ 200 = r^2 \times 8 \][/tex]

[tex]\[ 25 = r^2 \][/tex]

[tex]\[ r = 5 \][/tex]

Now that we have found the radius r to be 5 inches, we can calculate the area A of the cross-section of the cylinder using the formula for the area of a circle:

[tex]\[ A = \pi r^2 \][/tex]

[tex]\[ A = \pi \times 5^2 \][/tex]

[tex]\[ A = \pi \times 25 \][/tex]

[tex]\[ A = 25\pi \][/tex]

Therefore, the area of the cross-section of the cylinder is [tex]\( 25\pi \)[/tex] square inches.

[tex]\bf \begin{cases} f(x)=&10x+25\\ g(x)=&x+8 \end{cases}~\hspace{5em} \begin{array}{llll} f(~~g(x)~~)=&10[g(x)]+25\\\\ f(~~g(x)~~)=&10[x+8]+25\\\\ f(~~g(x)~~)=&10x+80+25\\\\ f(~~g(x)~~)=&10x+105 \end{array}[/tex]

Answer:

f(g(x)) = 10x + 105

Step-by-step explanation:

Start with f(x) = 10x + 25.  Replace this x with (x + 8), which is g(x):

f(g(x)) = 10(x + 8) + 25, or

         = 10x + 80 + 25, or 10x + 105

f(g(x)) = 10x + 105

Answer:

$280.51

Step-by-step explanation:

The formula we want to use:

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]

where:

P is the principal

r is the the rate

n is the number of compounding per year

t is total number of years

A is the ending amount

We are given P=200, r=.07, n=1 (compounded once a year), t=5.

So plugging this in:

[tex]A=200(1+\frac{.07}{1})^{1 \cdot 5}[/tex]

Simplify a little:

[tex]A=200(1+.07)^{5}[/tex]

Just a little more:

[tex]A=200(1.07)^{5}[/tex]

Now I'm going to put the rest of this in the calculator:

200*(1.07)^5 is what I'm putting in my calculator.

This is approximately 280.5103461.

To the nearest cent this is 280.51

Answer:

7

Step-by-step explanation:

Those are alternate interior angles. Alternate interior angles are the ones that happen at different intersections along the transversal but on opposite sides while inside the lines the transversal goes through. If these lines are parallel, then the alternate interior angles are congruent. Same thing the other way around. Alternate interior angles being congruent implies those lines are parallel.

So we are looking to solve:

3x-2=2x+5

Subtract 2d on both sides:

x-2=5

Add 2 on both sides:

x=7

The phrase "A || B" in a mathematical context usually indicates that line A is parallel to line B. To find the value of x that makes A parallel to B, we must generally consider the properties of parallel lines, specifically in relation to their slopes.
If A and B are lines in a coordinate plane, they will be parallel if and only if their slopes are equal and they are not the same line (in which case they would be coincident). If you are given the equations of the lines in the form y = mx + b, where m represents the slope and b represents the y-intercept, then A and B are parallel if the m values of both equations are the same.
Here's how you would generally find x when A and B are lines defined by equations:
1. Start with the equations of lines A and B. Both will typically be in a format that allows you to solve for their slopes.
   - Line A's equation might look like y = mx + c, where m is the slope of line A.
   - Line B's equation might look like y = nx + d, where n is the slope of line B.
2. Set their slopes equal to each other, as parallel lines have the same slope. This would give you the equation:
   m = n
3. If either slope contains a variable x that you need to solve for, create an equation for x by equating the two slopes:
   mx = nx
4. Solve for x. If the slopes contain x, they might be presented in a linear equation with x, or they could involve more complex expressions.
This is a high-level overview since the specifics would depend greatly on the actual equations of lines A and B. Without the explicit equations for lines A and B, I cannot give a numerical answer. If the question provided equations for lines A and B, please provide them, and I will assist you in finding the value of x that makes A parallel to B.

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here slope m = [tex]\frac{1}{2}[/tex], hence

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute (- 2, - 4) into the partial equation

- 4 = - 1 + c ⇒ c = - 4 + 1 = - 3

y = [tex]\frac{1}{2}[/tex] x - 3 ← equation of line

Answer:

Last choice

Step-by-step explanation:

V means or.

So we have x<0 or y<0.

This means we want the quadrant that have negative x's and we want the quadrants that have negative y's

x is negative to the left of the y-axis so it's negative in quadrants 2 and 3

y is negative below the x-axis so it's negative in quadrants 3 and 4.

So we are looking at all quadrants except quadrant 1.

as you already know to get the inverse of any expression, we start off by doing a quick switcheroo on the variables, and then solve for "y".

[tex]\bf y=x^2+16\implies \stackrel{\textit{quick switcheroo}}{\underline{x}=\underline{y}^2+16}\implies x-16=y^2\implies \sqrt{x-16}=\stackrel{f^{-1}(x)}{y}[/tex]

The formula of a distance between two points:

We have the points (3, 7) and (15, 16). Substitute:

[tex]d=\sqrt{(15-3)^2+(16-7)^2}=\sqrt{12^2+9^2}=\sqrt{144+81}=\sqrt{225}=15[/tex]

Answer:

22cm,24cm,24cm

Step-by-step explanation:

Let us call one of the other sides x

the shortest side = 2x-26

in an isosceles, 2 sides are equal (x in this case)

so we now have sides of x,x and 2x-26

form an eqution from this.

4x-26=70

4x=96

x=24

24 x 2 = 48 - 26 = 22

thus, the shortest side is 22cm and the other sides are both 24cm

Answer:

The lengths of the three sides in ascending order is.

_22__cm, __24__cm, __24__cm

Step-by-step explanation:

The perimeter of a triangle is equal to the sum of the length of its three sides.

By definition, an isosceles triangle has two equal sides.

We know that the short side measures  26 cm less than twice as long as the other sides, and that the other two sides are of equal length.

We also know that the perimeter of the triangle is 70 cm

Then we propose the following equation

[tex]P = b + 2s[/tex]

Where P is the perimeter, b is the shortest side of the triangle and s is the length of the equal sides.

Then:

[tex]b= 2s -26[/tex]

We substitute this equation in the first equation and solve for s

[tex]P = 2s -26 + 2s[/tex]

[tex]P = 4s -26=70[/tex]

[tex]4s -26=70[/tex]

[tex]4s=70 +26[/tex]

[tex]4s=96[/tex]

[tex]s=\frac{96}{4}[/tex]

[tex]s=24[/tex]

Then

[tex]b= 2(24) -26[/tex]

[tex]b= 22[/tex]

Answer:

{ -1, -3i,3i,4,-4}

Step-by-step explanation:

I'm going to try to get the Rational Root Theorem to work for us.

Since the coefficient of leading term is 1 we just need to look at the factors of the constant.

Possible rational zeros are going to be the factors of -144.

So here are some possible rational zeros: 1,2,3,4,6,8,9,12,16,18,24,36,48,72 and also the negative version of these numbers are numbers we must consider.

I'm going to see if -1 works.  

(-1)^5+(-1)^4-7(-1)^3-7(-1)^2-144(-1)-144

-1   +   1     +7      -7       +144  -144=0

So -1 is a zero so x+1 is a factor. I'm going to use synthetic division to see what multiplies to x+1 that will me the initial polynomial expression we had.

-1   |    1       1      -7        -7      -144    -144

     |           -1      0          7        0       144

     | ________ __________________

          1      0     -7         0       -144      0

So the (x+1)(x^4-7x^2-144)=0

The cool thing is that other factor is a sort of quadratic in disguise. That is it becomes a quadratic if you let u=x^2. So let's do that.

u^2-7u-144=0

(u+9)(u-16)=0

u=-9 or u=16

So x^2=-9 or x^2=16.

Square rooting both sides gives us:

[tex] x= \pm 3i \text{ or } x=\pm 4 [/tex]

So the solution set is { -1, -3i,3i,4,-4}

Answer:

Step-by-step explanation:

First identify the points that undergo transformation

You have;

A = (0,0)   and B =(1,3)

The transformation is T: (x,y)= (x+2, y+1), this means to get the image you add the x coordinate of the object to 2, and the y coordinate to 1.

Finding coordinates of the image points A' and B'

A'= (0+2,0+1) = (2,1)

B'=(1+2, 3+1)=(3,4)

Finding the distance A'B'

The formula for distance d is

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

where

x₁=2

x₂=3

y₁=1

y₂=4

d=distance between two points

Applying the formula

[tex]d=\sqrt{(3-2)^2+(4-1)^2} \\\\\\d=\sqrt{1^2+3^2} \\\\\\d=\sqrt{1+9} \\\\\\d=\sqrt{10} \\\\\\d=3.162[/tex]

The distance A'B' is √10 =3.162 units

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.

Given that:-

slice of pizza from a large pizza with a radius of 9 inches cut into 6 slices

The area of the slice will be 1 / 6 th of the total area of the pizza since the pizza is cut into six parts.

Area of slice = ( 1 / 6 ) x π ( 9² )

Area of slice = 13.5π square inches.

Answer:

D. (x, y, z) = (1, 1, 2). That is:

[tex]\left\{\begin{aligned}&x = 1\\ & y = 1 \\&z = 2\end{aligned}\right.[/tex].

Step-by-step explanation:

Step One: Make sure that the first coefficient of the first row is 1. In this case, the coefficient of [tex]x[/tex] in the first row is already 1.

Step Two: Using row 1, eliminate the first unknown of row 1 [tex]x[/tex] in the rest of the rows. For example, to eliminate [tex]x[/tex] from row 2, multiply row 1 by the opposite of the coefficient of [tex]x[/tex] in row 2 and add that multiple to row 2. The coefficient of [tex]x[/tex] in row 2 is [tex]3[/tex]. Thus, multiply row 1 by [tex]-3[/tex] to get its multiple:

[tex]-3x - 3y + 3z = 0[/tex].

Add this multiple to row 2 to eliminate [tex]x[/tex] in that row:

[tex]\begin{array}{lrrrcr}&-3x &-3y&+3z& =&0 \\ + & 3x& -y& +z& =& 4\\\cline{1-6}\\[-1.0em]\implies&&-4y &+ 4z&=&4\end{array}[/tex].

Similarly, for the third row, multiply row 1 by [tex]-5[/tex] to get:

[tex]-5x - 5y + 5z = 0[/tex].

Do not replace the initial row 1 with this multiple.

Add that multiple to row 3 to get:

[tex]\begin{array}{lrrrcr}&-5x &-5y&+5z& =&0 \\ + & 5x& & +z& =& 7\\\cline{1-6}\\[-1.0em]\implies&&-5y &+6z&=&7\end{array}[/tex].

After applying step one and two to all three rows, the system now resembles the following:

[tex]\left\{\begin{array}{rrrcr}x& + y & -z& = &0\\&-4y &+4z&=&4\\ &-5y &+6z&=&7\end{array}\right.[/tex].

Ignore the first row and apply step one and two to the second and third row of this new system.

[tex]\left\{\begin{array}{rrcr}-4y &+4z&=&4\\ -5y &+6z&=&7\end{array}\right.[/tex].

Step One: Make sure that the first coefficient of the first row is 1.

Multiply the first row by the opposite reciprocal of its first coefficient.

[tex]\displaystyle (-\frac{1}{4})\cdot (-4y) + (-\frac{1}{4})\cdot 4z = (-\frac{1}{4})\times 4[/tex].

Row 1 is now [tex]y - z = -1[/tex].

Step Two: Using row 1, eliminate the first unknown of row 1 [tex]y[/tex] in the rest of the rows.

The coefficient of [tex]y[/tex] in row 2 is currently [tex]-5[/tex]. Multiply row 1 by  [tex]5[/tex] to get:

[tex]5y - 5z = -5[/tex].

Do not replace the initial row 1 with this multiple.

Add this multiple to row 2:

[tex]\begin{array}{lrrcr}&-5y&+6z& =&7 \\ + & 5y& -5z& =& -5\\\cline{1-5}\\[-1.0em]\implies&&z &= &2\end{array}[/tex].

The system is now:

[tex]\left\{\begin{array}{rrcr}y & - z&=&-1\\& z &=&2\end{array}\right.[/tex].

Include the row that was previously ignored:

[tex]\left\{\begin{array}{rrrcr}x& + y & -z& = &0\\&y &-z&=&-1 \\ & &z&=&2\end{array}\right.[/tex].

This system is now in a staircase form called Row-Echelon Form. The length of the rows decreases from the top to the bottom. The first coefficient in each row is all [tex]1[/tex]. Find the value of each unknown by solving the row on the bottom and substituting back into previous rows.

From the third row: [tex]z = 2[/tex].

Substitute back into row 2:

[tex]y -2 = -1[/tex].

[tex]y = 1[/tex].

Substitute [tex]y = 1[/tex] and [tex]z = 2[/tex] to row 1:

[tex]x + 1 - 2 = 0[/tex].

[tex]x = 1[/tex].

In other words,

[tex]\left\{\begin{aligned}&x = 1\\ & y = 1 \\&z = 2\end{aligned}\right.[/tex].

Step-by-step explanation:

Adam Smith said that the natural price is the price which covers all the costs to produce it for instance, rent of land, wages of labour, cost of machinery.

A. The price of any item that is less than costs of producing it

This is incorrect since natural price covers all costs of production,

B. The price of any item that is equal to its market price.

C. The price of any item that is less than its market price

Both B and C are incorrect because market price is determined by the forces of demand and supply and changes accordingly whereas the natural price is the everyday normal price.

D. The price of any item that is equal to the costs of producing it.

This is correct because the natural price covers all costs involved in producing a product and is neither low nor high.

Part C: Natalie can only attend a school in her designated zone. Natalie's zone is defined by y < −2x + 2. Explain how you can identify the schools that Natalie is allowed to attend.

we have

[tex]y < -2x+2[/tex]

The solution of the inequality is the shaded area below the dotted line [tex]y=-2x+2[/tex]

The y-intercept of the dotted line is the point (0,2)

The x-intercept of the dotted line is the point (1,0)

To graph the inequality, plot the intercepts and shade the area below the dotted line

see the attached figure N 2

therefore

The schools that Natalie is allowed to attend are A,B and D

First find the decreased value,

[tex]777-777\cdot0.12=777-93.24=683.76[/tex]

Then from the value found, find increased value,

[tex]683.76+683.76\cdot0.04\approx\boxed{711.11}[/tex]

Hope this helps.

The answer is 855 miles.

Problem-solving is the act of defining a problem; figuring out the purpose of the trouble; identifying, prioritizing, and selecting alternatives for an answer; and imposing an answer.

Problem-solving starts with identifying the issue. As an example, a trainer may need to parent out a way to improve a scholar's overall performance on a writing talent test. To do that, the instructor will overview the writing exams looking for regions for improvement.

Answer:

[tex]x^6+x^4+4x^3-2x^2-x+3[/tex]

Step-by-step explanation:

[tex]x^3+2x+3[/tex]

[tex]\times(x^3-x+1)[/tex]

---------------------------------

First step multiply your terms in your first expression just to the 1 in the second expression like so:

[tex]x^3+2x+3[/tex]

[tex]\times(x^3-x+1)[/tex]

---------------------------------

[tex]x^3+2x+3[/tex]  Anything times 1 is that anything.

That is, [tex](x^3+2x+3) \cdot 1=x^3+2x+3[/tex].

Now we are going to take the top expression and multiply it to the -x in the second expression. [tex]-x(x^3+2x+3)=-x^4-2x^2-3x[/tex].  We are going to put this product right under our previous product.

[tex]x^3+2x+3[/tex]

[tex]\times(x^3-x+1)[/tex]

---------------------------------

[tex]x^3+2x+3[/tex]

[tex]-x^4-2x^2-3x[/tex]  

We still have one more multiplication but before we do that I'm going to put some 0 place holders in and get my like terms lined up for the later addition:

[tex]x^3+2x+3[/tex]

[tex]\times(x^3-x+1)[/tex]

---------------------------------

[tex]0x^4+x^3+0x^2+2x+3[/tex]

[tex]-x^4+0x^3-2x^2-3x+0[/tex]  

Now for the last multiplication, we are going to take the top expression and multiply it to x^3 giving us [tex]x^3(x^3+2x+3)=x^6+2x^4+3x^3[/tex]. (I'm going to put this product underneath our other 2 products):

[tex]x^3+2x+3[/tex]

[tex]\times(x^3-x+1)[/tex]

---------------------------------

[tex]0x^4+x^3+0x^2+2x+3[/tex]

[tex]-x^4+0x^3-2x^2-3x+0[/tex]  

[tex]x^6+2x^4+3x^3[/tex]

I'm going to again insert some zero placeholders to help me line up my like terms for the addition.

[tex]x^3+2x+3[/tex]

[tex]\times(x^3-x+1)[/tex]

---------------------------------

[tex]0x^6+0x^4+x^3+0x^2+2x+3[/tex]

[tex]0x^6-x^4+0x^3-2x^2-3x+0[/tex]  

[tex]x^6+2x^4+3x^3+0x^2+0x+0[/tex]

----------------------------------------------------Adding the three products!

[tex]x^6+x^4+4x^3-2x^2-x+3[/tex]
