Answers

Answer 1
 The correct answer is:  [C]:  " [tex] \frac{21}{11} [/tex] " . 
_____________________________________________________

Explanation:
_____________________________________________________

Let us begin by converting the:  
"0.42 (with the "repeating bar on the digits, "42") " ;  

into a fraction, as follows:
______________________________________________________
   Let  x = 0.42424242424242424242424242424242....

100x = 42.42424242424242424242424242424242....
______________________________________________________
    
         100x = 42.42424242424242424242424242424242....
    –         x =   0.42424242424242424242424242424242...
______________________________________________________
          99x = 42.000000000000000000000000000000.... ;

         →   99x = 42 ;  

Divide each side of the equation by " 99 " ;  
       to isolate "x" on one side of the equation; & to solve for "x" ; 
______________________________________________________
         →  99x / 99 = 42/99 = (42 ÷ 3) / (99 ÷ 3) = 14/ 33; 

         →  x = "[tex] \frac{14}{33} [/tex]" .

So;  "0.42 (with a repeating bar over the digits, "42" ;

           is equal to:  "[tex] \frac{14}{33} [/tex]" 
________________________________________________
 So, rewrite the question/problem being asked:
________________________________________________
  "Find the quotient:  
________________________________________________
   [tex] \frac{14}{33} [/tex]  ÷ [tex] \frac{2}{9} [/tex]  ;

=  [tex] \frac{14}{33} [/tex] * [tex] \frac{9}{2} [/tex]  ;

Note:  The "14" cancels to a "7" ; and the "2" cancels to a "1" ; 
       →  {since:  " 14 ÷ 2 = 7 " ; and since:  " 2 ÷ 2 = 1 "} ;

Note : The "33" cancels to an "11" ; and the "9" cancels to a "3" ;
        →  {since:  " 33 ÷ 3 = 11 " ; and since:  " 9 ÷ 3 = 3 "} ;

And we can rewrite the problem as:
____________________________________________________
 
 " [tex] \frac{7}{11} [/tex]  * [tex] \frac{3}{1} [/tex] "  ;

  =  [tex] \frac{(7*3)}{(11*1} [/tex]   =  [tex] \frac{21}{11} [/tex]

            → which is:  Answer choice:  [C]:  " [tex] \frac{21}{11} [/tex] " .

Answers

Answer(a):

Exponential growth formula is given by

[tex]A=P(1+r)^t[/tex]

Where preset population = P= 775

Rate of increase = r = 51% = 0.51

t= number of years

A= Future value.

Plug these values into above formula:

[tex]A=775(1+0.51)^t[/tex]

[tex]A=775(1.51)^t[/tex]

Hence required exponential function is [tex]A=775(1.51)^t[/tex]


Answer(b):

plug t=10 years

[tex]A=775(1.51)^t=775(1.51)^{10}=775(61.6267795034)=47760.7541151[/tex]

which is approx 47761.


Answer(c):

Plug A=1150

[tex]1150=775(1.51)^t[/tex]

[tex]\frac{1150}{775}=(1.51)^t[/tex]

[tex]\ln(\frac{1150}{775})=t*\ln(1.51)[/tex]

Write the equation of the circle with center (0, 0) and (5, 2) a point on the circle.

Answers

we know that
the equation of the circle with center (0, 0) is ---------> x²+y²=r²

Step 1
find the radius
the radius is simply the distance from the center to the point (5,2)
d=√[(5²+2²)]-------> d=√29
r=√29
the equation of the circle is
x²+y²=29

the answer is x²+y²=29

1. You have that:

 r²=(x-h)²+(y-k)²

 2. The center of this circle is (0,0), then:

 h=0
 k=0

 3. When you substitute the values of h and k into the equation, you have:

 r²=(x-h)²+(y-k)²
 r²=(x-0)²+(y-0)²
 r²=x²+y²

 3. Now, you must find the radius "r".

 4. You know that the point is (5,2), so:

 r²=x²+y²

 5. Finally:

 √29=x²+y²

Write the equation in slope-intercept form of the line that has a slope of -5 and a y-intercept of 2.

Answers

Hi!

Slope intercept form is in the form y=mx+b
m is the slope, and that is given so we can plug that into the equation

y = -5x + b

We are also given the y-intercept (0,2) and we can plug that into the equation as well, to find b

2 = 5(0) + b
2 = b

So now that we know both m and b, plug only those two into the equation.
y = -5x + 2

That is your equation

4. find the real number roots. sqrt-0.25

Answers

Given is square root of a negative real number, i.e. [tex] \sqrt{-0.25} [/tex]

When we find square root of positive real numbers, we get Real answers.

But when we find square root of negative real numbers, we get Imaginary answers. To solve them, we can split the given negative number into product of -1 and the number itself but with positive sign. e.g. -4 = -1 x 4.

For square root of -1, we use english letter 'i' called Imaginary unit i.e. [tex] \sqrt{-1} = i [/tex]

Now we can use -0.25 = -1 x 0.25

[tex] \sqrt{-0.25} =\sqrt{-1*0.25} \\\\
\sqrt{-0.25} =\sqrt{-1}*\sqrt{0.25} \\\\
\sqrt{-0.25} =i*0.5 \\\\
\sqrt{-0.25} =0.5i [/tex]

Hence, "0.5i" is the final answer.

The square root of -0.25 is not a real number because the square root of a negative number is not defined within the set of real numbers.

The square root of a negative number is not a real number. In the case of √(-0.25), the expression is undefined within the set of real numbers because taking the square root of a negative number results in a complex number. The square root of a negative number is typically represented using the imaginary unit "i" in the complex number system. Therefore, √(-0.25) is not a real number.

Answer:

[tex]m\angle D=29.05[/tex]

Step-by-step explanation:

We have been given an image of a right triangle and we are asked to find the measure of angle D.

We can see from our given triangle that the opposite side of angle D measures 25 ft and adjacent side of angle D is 45 ft.

Since we know that tangent represents the relation between the opposite and adjacent sides of a right triangle.

[tex]\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}[/tex]

Upon substituting our given values in above formula we will get,

Hello!

I'll solve the first two systems.

1)

Multiply the second equation in the system by 2 to be able to cancel out y-terms:

[tex]-x-y=-9[/tex]
[tex]2(-x-y=-9)[/tex]
[tex]-2x-2y=-18[/tex]

Now, add the equations together:

[tex] \left \ {{5x+2y=21} \atop {-2x-2y=-18}} \right. [/tex]
_____________
[tex]3x-0=3[/tex]
[tex]3x=3[/tex]
[tex]x=1[/tex]

Plug 1 for x into one of the original equations to find y:

[tex]5x+2y=21[/tex]
[tex]5(1)+2y=21[/tex]
[tex]5+2y = 21[/tex]
[tex]2y=16[/tex]
[tex]y =8[/tex]

Check work by plugging your values for x and y back into both original equations:

[tex] \left \ {{5x+2y=21} \atop {-x-y=-9}} \right. [/tex]

[tex] \left \ {{5(1)+2(8)=21} \atop {-(1)-(8)=-9}} \right. [/tex]

[tex] \left \ {{5+16=21} \atop {-1-8=-9}} \right. [/tex]

Both are true; x = 1 and y = 8.

2)
[tex] \left \ {{3x+2y=13} \atop {3x+4y=1}} \right. [/tex]

For this system, to be able to cancel out x-terms, you can multiply either equation by -1; I'll use the bottom equation:

[tex]-1(3x+4y=1)[/tex]
[tex]-3x-4y=-1[/tex]

Now add the equations together:

[tex] \left \ {{3x+2y=-13} \atop {-3x-4y=-1}} \right. [/tex]
_____________
[tex]0-2y=-14[/tex]
[tex]-2y = -14[/tex]
[tex]y=7[/tex]

Plug 7 for y into either of the original equation to solve for x:

[tex]3x+2(7)=-13[/tex]
[tex]3x+14=-13[/tex]
[tex]3x = -27[/tex]
[tex]x=-9[/tex]

Plug -9 for x and 7 for y into each original equation to check work:

[tex] \left \ {{3(-9)+2(7)=-13} \atop {3(-9)+4(7)=1}} \right. [/tex]

[tex] \left \ {{-27+14=-13} \atop {-27+28=1}} \right. [/tex]

Both are correct; x = -9 and y = 7.

Apply these steps to the last two systems and you're good to go. (:

What does the 80 inches represent in an 80" TV

Answers

It represents the distance diagonally between two opposite corners of a Television. (i.e. the distance between the bottom-left corner and the top-right corner)

The 80 inches on an 80" TV refers to the diagonal measurement of the screen, which determines the size of the TV. This measurement is essential for potential buyers to know to match the TV to their space and optimal viewing distance. Other factors like screen resolution and whether to choose plasma or LCD also influence the viewing experience and cost.

When we refer to an 80" TV, the 80 inches represents the diagonal measurement of the screen. This measurement is taken from one corner to the opposite corner of the screen, not horizontally or vertically, which is the standard for sizing televisions and monitors. The importance of considering screen size arises from the need to match the viewer's space and viewing distance to optimize the viewing experience. With larger screens, such as an 80-inch TV, viewers can enjoy a more immersive viewing experience, especially when watching sports, movies, or DVDs. However, depending on the resolution, like 1080p for full HD or 768p for a lower resolution, the quality of the image may affect the perceived difference in quality, especially on smaller screens in which it might not be distinguishable to the nak.ed eye.

Mrs. Gomez is sewing a dress for each of her four daughters. Each dress uses 2.25 yards of fabric, and the fabric costs $4.15 per yard. What will be the cost for fabric for all four dresses? Show your work, including labeling your answer with the appropriate units of measure.

Answers

2.25 yd * 4.15/yd = $ 9.3375 = $9.34

Answer:

The cost for fabric for all four dresses is $37.35

Step-by-step explanation:

Each Dress requires fabric = 2.25 yards

Fabric required for 4 dresses = [tex]2.25 \times 4[/tex]

                                               = [tex]9yards[/tex]

Cost of 1 yard fabric = $4.15

Cost of 9 yard fabric = [tex]4.15 \times 9[/tex]

                                  = $37.35

Hence the cost for fabric for all four dresses is $37.35

find the difference 6x^2-14x+4/x(x-2) - 6x-1/x+1

Answers

Final answer:

To find the difference between two expressions in the given question, you need to simplify each expression first and then subtract them. The steps involve simplifying each expression separately and then performing the subtraction.

Explanation:

To find the difference 6x² - 14x + 4 / x(x - 2) - 6x - 1 / x + 1, you need to first simplify each expression and then subtract them from each other.

Step 1: Simplify each expression separately.

6x² - 14x + 4 / x(x - 2) = (3x - 2)(2x - 1) / x(x - 2) = 3(2x - 1) / x

- 6x - 1 / x + 1 = -6 - 1 / x + 1 = -7 / (x + 1)

Step 2: Subtract the two simplified expressions: 3(2x - 1) / x - 7 / (x + 1).

PART A: All but two of the pyramids built by the ancient Egyptians have faces inclined at 52 degree angles. Suppose an archaeologist discovers the ruins of a pyramid. Most of the pyramid has eroded, but the length of a side of the square base is 82 meters. How tall was the pyramid, assuming its faces were inclined at 52 degrees? Round your answer to the nearest meter.

25 m
32 m
52 m
105 m,

Answers

The height is 52m.

The height forms a right triangle with the slant height of the pyramid and half of the length of the square base.  Half of the length of the square base would be 41m.  The angle is 52°.  The sides we have are the height, which is opposite the angle, and half of the base, which is adjacent to the angle.  The ratio opposite/adjacent is used for the tangent.  Our equation would be:

tan 52=h/41

We multiply both sides by 41:
41*tan 52 = (h/41)*41
41*tan 52 = h

Evaluating this we get 52m.

In the problem, we were asked to compute for the height of the pyramid. Given are the base of the pyramid which is 82 m and the angle of 52°.

If given an illustration, the height is opposite to the angle and the adjacent side is given by half the base.

Based on the mnemonics of trigonometry (SOH CAH TOA), the function to be used is tangent.

The computation is as follows:

Let h = height of pyramid (m)

tan52 = h/41

h = 41tan52

8(y + 12)
= 8y + 96 (Answer D)

The expression 8(y + 12) simplifies to 8y + 96 using the distributive property, which involves multiplying 8 by both y and 12.

The question asks us to simplify the expression using the distributive property. The expression given is 8(y + 12). To simplify, we apply the distributive property by multiplying 8 with both y and 12.

So, we have:

8(y) + 8(12) = 8y + 96.

Therefore, the simplified form of the expression 8(y + 12) is 8y + 96.

Four times the larger of two numbers is equal to seven times the smaller. the sum of the numbers is 22. what are the numbers?

Answers

Answer:

The larger is 14 the smaller is 8

Explanation:

Let the larger number be L and the smaller be S
So we know that

1) L+S=22
And
2)4L=7S
From equation 1) we get L=22-S

Substitute this into equation 2) to get 4(22-S)=7S
88-4S=7S
88=11S
S=8. The smaller number is 8

As they total 22 the larger number is 14.
Check: 4x14=7x8. Yes

Solution 2:

Let x= larger number
And let y= smaller. umber

Now we are told that:
4x=7y--------eq1
We are also told that:
x + y=22-----eq2

Substitution method looks easier.


From eq1 x=(7/4)y. Substitute this into eq2
(7 /4)y +y=22
(7/4)y+(4/4)y=22
(11/4)y=22 multiply each side by 4
11y=88
y=8

From eq2, x+8=22
x=14

Hope this helps

Final answer:

To find the two numbers where four times the larger is equal to seven times the smaller, and the sum is 22, we set up a system of equations and solve them. We find that the larger number is 14 and the smaller number is 8.

Explanation:

To solve the question "Four times the larger of two numbers is equal to seven times the smaller. The sum of the numbers is 22. What are the numbers?", we use a system of equations. First, we assign variables to the unknowns: let x be the larger number and y be the smaller number. According to the problem, we have two equations:

4x = 7y (because four times the larger number is equal to seven times the smaller)

x + y = 22 (because the sum of the numbers is 22)

Now, we can solve for one of the variables. Let's isolate y in the second equation:

y = 22 - x

Substitute this expression for y into the first equation:

4x = 7(22 - x)

Expand and solve for x:

4x = 154 - 7x

11x = 154

x = 14

Then we find y by substituting x back into the equation y = 22 - x:

y = 22 - 14

y = 8

Therefore, the larger number is 14 and the smaller number is 8.

What is distance between two points?

The length of the line segment bridging two points on a plane is known as the distance between the points.

The formula to find the distance between the two points is usually given by d=√{(x₂-x₁)² + (y₂-y₁)²}

Two line segments AB and CD have endpoints at A (-5, 11), B(3, 5), C (9, 3) and D (2, 10).

To find the distance:

The distance of two points

= √ {(x₂-x₁)² + (y₂-y₁)²}

The distance of segment AB

= √ {(3+5)² + (5-11)²}

=  √ {(8)² + (-7)²}

=  √(64 + 49)

= √(64 + 49)

= √113

= 10.63 unit.

The distance of segment CD

= √ {(2-9)² + (10-3)²}

=  √ {(-7)² + (7)²}

=  √(49 + 49)

= √98

= 9.9 unit.

Clearly, distance of AB > distance of CD

Therefore, distance of AB > distance of CD.
