Show step by step how to solve and check (giving 10 points)

Answer:

B)

Step-by-step explanation:

First, lets try to build the second equation, it has the general shape

[tex]y=m *x+b[/tex]

Where b is a constant (a number) and m the slope, another constant.

Using the given condition (0,-7) you can find the first constant of our second equation, just put "0" where you see "x", and put -7 where there is a "y".

That gives us that b is equals to -7.

Now we only need to know that the condition for 2 linear equations to be parallels is that their slope have to be the same or multiple between each others, this means that "m" of our second equation has to be equal to 1/2

thus, our second equation is [tex]y=\frac{1}{2}*x-7[/tex]

Another way to see this is that you can compare two linear equations y1=m1*x1 + b1, and y2=m2*x2+b2, if these two intersect in somewhere, this condition should meet:

X= (b1-b2)/(m2-m1).

If the slopes are the same, the above equation gives us an error, meaning that the linear equations are, in fact parallels.

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.

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:

Step-by-step explanation:

The formula of a distance between two points:

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

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:

(2,-3) and (-2,5)

Step-by-step explanation:

Let us graph the two equations one by one.

1. [tex]f(x)=-2x+1[/tex]

If we compare this equation with the slope intercept form of a line which is given as

[tex]y=mx+c[/tex]

we see that m = -1 and c =1

Hence the slope of the line is -2 and the y intercept is 1. Hence one point through which it is passing is (0,1) .

Let us find another point by putting x = 1 and solving it for y

[tex]y=-2(1)+1[/tex]

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

Let us find another point by putting x = 2 and solving it for y

[tex]y=-2(2)+1[/tex]

[tex]y=-4+1 = -3[/tex]

Hence the another point will be (2,-3)

Let us find another point by putting x = -2 and solving it for y

[tex]y=-2(-2)+1[/tex]

[tex]y=+1 = 5[/tex]

Hence the another point will be (-2,5)

Now we have two points (0,1) ,(1,-1) ,  (2,-3) and (-2,5) we joint them on line to obtain our line  

2.

[tex]g(x)=y=x^2-2x-3[/tex]

[tex]y=x^2-2x+1-1-3[/tex]

[tex]y=(x-1)^2-4[/tex]

[tex](y+4)=(x-1)^2[/tex]

It represents the parabola opening upward with vertices (1,-4)

Let us mark few coordinates so that we may graph the parabola.

i) x=0 ; [tex]y=y=(0)^2-2(0)-3=0-0-3=-3[/tex] ; (0,-3)

ii)x=-1 ; [tex]y=(-1)^2-2(-1)-3=1+2-3=0[/tex] ; (-1,0)

iii) x=2 ; [tex]y=(2)^2-2(2)-3 = 4-4-3 =-3[/tex] ;(2,-3)

iii) x=1 ; [tex]y=(1)^2-2(1)-3 = 1-2-3 =-4[/tex]  ;(1,-4)

iii) x=-2 ; [tex]y=(-2)^2-2(-2)-3 = 4+4-3 =5[/tex]  ;(-2,5)

Now we plot them on coordinate axis and line them to form our parabola

When we plot them we see that we have two coordinates (2,-3) and (-2,5) are common , on which our graphs are intersecting. These coordinates are solution to the two graphs.

Step-by-step explanation:

Answer:

No.

Step-by-step explanation:

The circle of that equation lies on the point (3,1) as its furthest point to the right (x-axis) and therefore could never also lie on the point (3,-1).

Your equation is in center radius form, which is as follows:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Noting that your radius is 4 (since your radius squared is 16).

To graph your circle, simply go to your origin (h, k) which in this case is (-1, 1) and then count out in any direction (up, down, left, or right -- no diagonals) 4 units (since your radius is 4). This will give you the four outermost edges of your circle. Simply fill in the gaps from there, and you'll have sketched your circle.

No. The circle of that equation lies on the point (3,1) as its furthest point to the right (x-axis) and thus could never  lie on the point (3,-1).

A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.

The equation is in center radius form, which is as follows:

(x - h)² + (y - k)² = r²

the radius is 4 (since your radius squared is 16).

Substituting 3 for x and -1 for y:

(3 + 1)^2 + (-1 - 1)^2 = 16

4^2 + (-2)^2 = 16

16 + 4 = 16

20 = 16

Hence, we can see 20 is clearly not equal to 16, so we know the point (3, -1) can’t lie on that circle.

Answer:

Law of Cosines; A ≈ 61°, B ≈ 89°, C ≈ 30°

Step-by-step explanation:

In this problem the given values are the length sides of the triangle, therefore, the triangle should be solved by beginning with the Law of Cosines

step 1

Applying the law of cosines find the value of angle C

we know that

[tex]c^{2}=a^{2}+b^{2}-2(a)(b)cos(C)[/tex]

we have

[tex]a = 8, b = 7, c = 4[/tex]

substitute the values and solve for cos(C)

[tex]4^{2}=8^{2}+7^{2}-2(8)(7)cos(C)[/tex]

[tex]16=64+49-112cos(C)[/tex]

[tex]16=113-112cos(C)[/tex]

[tex]112cos(C)=113-16[/tex]

[tex]cos(C)=97/112[/tex]

[tex]C=arccos(97/112)=30\°[/tex]

step 2

Applying the law of cosines find the value of angle B

we know that

[tex]b^{2}=a^{2}+c^{2}-2(a)(c)cos(B)[/tex]

we have

[tex]a = 8, b = 7, c = 4[/tex]

substitute the values and solve for cos(B)

[tex]7^{2}=8^{2}+4^{2}-2(8)(4)cos(B)[/tex]

[tex]49=64+16-64cos(B)[/tex]

[tex]49=80-64cos(B)[/tex]

[tex]64cos(B)=80-49[/tex]

[tex]cos(B)=31/64[/tex]

[tex]B=arccos(31/64)=61\°[/tex]

step 3

Find the measure of angle A

we know that

The sum of the interior angles of a triangle must be equal to 180 degrees

so

[tex]A+B+C=180\°[/tex]

we have

[tex]C=30\°[/tex]

[tex]B=61\°[/tex]

substitute and solve for A

[tex]A+61\°+30\°=180\°[/tex]

Tan(60) = opposite / adjacent

adjacent = 26

Cos(39) = adjacent / hypotenuse

Solution

Tan(60) = opposite (which is the height) / 26            Multiply both sides by 26

26*tan(60) =  opposite                                                  Multiply the left.

tan60 = 1.732

26 * 1.732 = opposite

45.033

====================                

Cos(39) = adjacent / hypotenuse

cos(39) = 0.7771

0.7771 = 45.0333 / x              Multiply both sides by x

0.7771*x = 45.0333                Divide by 0.7771

x = 45.0333 / 0.7771

x = 57.94

Answer:

option C

Step-by-step explanation:

We  have to find the value of x

[tex]tan\theta=\frac{perpendicular side}{base}[/tex]

[tex]tan60^{\circ}=\frac{height}{26}[/tex]

We know that [tex] tan60^{\circ}=\sqrt3[/tex]

[tex]\sqrt3=\frac{height}{26}[/tex]

[tex]height=1.732\times 26[/tex]

Where [tex]\sqrt3=1.732[/tex]

Height=45.032

Height=45.0

[tex]cos\theta=\frac{bas}{hypotenuse}[/tex]

[tex] cos 39^{\circ}=\frac{45}{x}[/tex]

[tex]0.777=\frac{45}{x}[/tex]

[tex]x=\frac{45}{0.777}[/tex]

x=57.9

Hence, option C is true.

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:

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:

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.

The slope-intercept form of a line is y=mx+b where m is the slope and b is the y-intercept.

Parallel lines will have the same slope and different y-intercept.

Anyways the slope of y=-2x+1 is -2.

So the equation of our line we are looking for is -2.

So we know our equation is in the form y=-2x+b.

We must inf b using y=-2x+b with (x,y)=(2,2).

y=-2x  +b  with (x,y)=(2,2)

2=-2(2)+b

2=-4+b

Add 4 on both sides:

2+4=b

Simplify:

6=b

The equation is y=-2x+6.

Now it didn't say what form it wanted.

There are some forms I can give you like standard and point-slope form.

There is also general form but it is not too much different from standard form.

Standard form is ax+by=c where a,b, and c are integers if possible.

Point-slope form is y-y1=m(x-x1) where (x1,y1) is a point on the line and m is the slope.

So let's go for standard form (ax+by=c) first:

y=-2x+6

add 2x on both sides:

2x+y=6

This is standard form because it is in the form

ax+by=c.

Ok we know point (2,2) is on our line and we also know we have slope,m, is -2.

Point-slope form is

y-y1=m(x-x1)

y-2=-2(x-2)

The segment bisects \AEC because \AEB and \BEC are both 45\u00b0, proven using the Angle Addition Postulate and the Subtraction Property of equality.

To prove that the segment bisects \AEC, begin by acknowledging the given information that m\AEB = 45\u00b0 and \AEC is a right angle with a measure of 90\u00b0. According to the Angle Addition Postulate, m\AEB + m\BEC = m\AEC. Substitute the known values to get 45\u00b0 + m\BEC = 90\u00b0. Utilizing the Subtraction Property of equality allows us to solve for m\BEC, finding it to also be 45\u00b0. This means that \BEC ≅ \AEB which leads us to conclude that since they have equal measures, the segment indeed bisects \AEC.

Answer:

3+(6-2)*4=19

Step-by-step explanation:

Due to PEMDAS, it would first be required to do "6-2", which is 4.

Then, the 4 in the parenthesis is multiplied by the 4 on the outside, making 16.

Finally, 3 would be added to 16, making 19.

Answer:

[tex]\large\boxed{\frac{1}{1}\,\text{or}\,1}[/tex]

Step-by-step explanation:

In this question, we're trying to find the slope with the given points.

To find the slope, we're going to need to sue the slope formula.

Slope formula:

[tex]\text{Slope}=\frac{y2-y1}{x2-x1}[/tex]

You would plug in the coordinates to its right spot.

Plug in -2 to x1, 3 in y1, 2 in x2, and 7 in y2.

Your equation should look like this:

[tex]\text{Slope}=\frac{7-3}{2-(-2)}[/tex]

Now, you will solve:

[tex]\text{Slope}=\frac{7-3}{2-(-2)}\\\\\text{Slope}=\frac{4}{2-(-2)}\\\\\text{Carry the minus sign over to the -2, turning it to a positive 2}\\\\\text{Slope}=\frac{4}{2+2}\\\\\text{Slope}=\frac{4}{4}\\\\\text{Divide}\\\\\text{Slope}=\frac{1}{1}=1[/tex]

When you're done solving, you should get 1.

This means that the slope of the line is 1/1 or 1

Finding the slope using two points:

The formula for slope is

[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

In this case...

[tex]y_{2} =7\\y_{1} =3\\x_{2} =2\\x_{1} =-2[/tex]

^^^Plug these numbers into the formula for slope...

[tex]\frac{7-3}{2 - (-2)}[/tex]

[tex]\frac{4}{4}[/tex]

^^^This can be further simplified down to...

1

^^^This is your slope

Answer:

[tex]\large\boxed{y-5=-\dfrac{2}{3}(x+3)}[/tex]

Step-by-step explanation:

The point-slope form of an equation of a line:

[tex]y-y_1=m(x-x_1)[/tex]

m - slope

(x₁, y₁) - point on a line

We have the slope [tex]m=-\dfrac{2}{3}[/tex] and the point [tex](-3,\ 5)[/tex].

Substitute:

[tex]y-5=-\dfrac{2}{3}(x-(-3))\\\\y-5=-\dfrac{2}{3}(x+3)[/tex]
