Answer:

[tex]A = \frac{1}{(x-1)(x+1)}[/tex]

Step-by-step explanation:

Looking at the dashed lines in the graphic, these functions have two discontinuities, at x = -1 and at x = 1.

A discontinuity in a rational function is a point in which the denominator of the function is 0.

For these options, the denomiator is 0 at both x = -1 and x = 1 for only option A, so the answer is:

[tex]A = \frac{1}{(x-1)(x+1)}[/tex]

Distance = speed x time

Distance = 240 x 3 = 720 miles

Answer:

[tex]2\frac{2}{3}[/tex] cubic blocks

Step-by-step explanation:

The given parameters are:

[tex]Length = \frac{1}{2}yd[/tex]

[tex]Width = 16yd[/tex]

[tex]Height =\frac{1}{3}yd[/tex]

Required

Number of cubic blocks to fill the tank

To do this, we simply calculate the volume of the tank by:

[tex]Volume = Length * Width * Height[/tex]

This gives:

[tex]Volume = \frac{1}{2} * 16 * \frac{1}{3}[/tex]

[tex]Volume = \frac{16}{6}[/tex]

Simplify

[tex]Volume = \frac{8}{3}[/tex]

Express as mixed numbers

[tex]Volume = 2\frac{2}{3}yd^3[/tex]

Answer:

C

Step-by-step explanation:

the formula for simple interest is given as A=P(1+rt), where A is the final balance, P is the initial principal balance (the amount of money that you start out with), r is the annual interest rate, and t is the time

we know that the mom deposited 2000 into an account when the person was born. This is our initial principal balance (the amount of money started out with)

substitute that value into the formula to get:

A=2000(1+rt)

we also know the rate, which is 5% and the time, which is 18

5%=0.05 (we need it as a decimal)

so substituting the values into the equation:

A=2000(1+0.05*18)

A=2000(1+0.9)

A=2000(1.9)

A=3,800

therefore the answer is C

Hope this helps!

Answer:

190 is 76% of 250

Step-by-step explanation:

We have, 76% × x = 190

Multiplying both sides by 100 and dividing both sides by 76,

we have x = 190 × 100/76

x = 250

If you are using a calculator, simply enter 190×100÷76, which will give you the answer.

The answer is 59in

Answer:

242 in^2

Step-by-step explanation:

Area of a rectangle is length x width.

Area of rectangle:  24 in x 7 in = 168 in^2

Area of a trapezoid is 1/2(height)(base 1 + base 2)

Area of the trapezoid on top is 1/2(4)(13+24) = 2(13 + 24) = 2(37) = 74.

The total are is 168 + 74 = 242 in^2

Answer:

[tex]\frac{27}{8}[/tex]

Step-by-step explanation:

[tex]\left(\frac{16}{81}\right)^{\frac{-3}{4}}=\frac{16^{\frac{-3}{4}}}{81^{\frac{-3}{4}}}[/tex]

[tex]=\frac{2^{-3} }{3^{-3} }[/tex]

[tex]=\frac{\frac{1}{8}}{\frac{1}{27}}[/tex]

[tex]=\frac{1*27}{8*1}[/tex]

[tex]=\frac{27}{8}[/tex]

Answer:

To find the radius, just take half of the diameter. The answer is 2.

Step-by-step explanation:

Semicircle Area and Perimeter

Area (A)

6.2832in²

A = πr²/2 = 2 * π [in²] ≈ 6.2832 [in²]

Perimeter (L)

10.2832 in

L = πr + d = 2 * π + 4 [inch] ≈ 10.2832 [inch]

Hope this helped!!!

The radius of the semicircle is 2 kilometers.

A straight line that runs through the sideways of a body or figure, particularly a circle or sphere, is called as a diameter of a circle or sphere.

Given:

The diameter of a semicircle is 4 kilometers.

Then the radius of the semicircle,

= diameter / 2

= 4/2

= 2 kilometers.

Therefore, the radius is 2 kilometers.

Answer: 54 cm²

Step-by-step explanation:

To find the area we have to:

1) Multiply 3 x 3= 9 (we do this because a cube has equal sides so if the height is 3 then the base will be 3).

2) Then take 9 and multiply it by the number of sides of a cube (6 sides)

so, do 9 x 6 = 54cm²

Hope that helped! :)

Answer:

54 cm^3

Step-by-step explanation:

here's your solution

==> surface area of cube = 6a^2

==> a = 3 cm

==> surface area = 6*3^2

==> surface area = 6*9

==> surface area of cube = 54 cm^3

62° & 54°

Step-by-step explanation:

Answer 21 :-

We know that the measure of a straight line is 180° .

Answer 22:-

Answer:

62° & 54°

Step-by-step explanation:

Answer 21 :-

We know that the measure of a straight line is 180° .

x + 118° = 180°

=> x = 180° - 118°

=> x = 62°

Answer 22:-

2x + 1 + 71 = 180

=> 2x = 180 - 72  

=> 2x = 108

=> x = 54°

Answer:

Step-by-step explanation:

just pick three values (numbers)  into the function and calculate the other unknown

You can pick an X or you can pick a Y, then solve for Y or X respectively.

Record these x,y pairs in the table

once you have at least two points you can graph the function

           y = mx + b     y-intercept form of the line function

                                  m = slope    b is the value of y when x = 0

   y = -5x/2 -5      let x = 0      solve for y

   y = -5(0)/2 -5

   y =    0 - 5

   y = -5

  y = -5x/2 -5                          solve for x            

  y + 5 = -5x/2 - 5 + 5             add 5 to both sides

  y + 5 = - 5x/2

 (y +5 )(-2/5)  = (-5x/2) (-2/5)

 (y +5 )(-2/5)  = x       let y = 0    

(0) +5)(-2/5)  = x

      5(-2/5)  = x

           -2   =  x

I'll let you have the third variable to pick  and solve for the dependent variable.  The dependent variable is just wha it sounds like, it is dependent on which ever independent (the value you randomly pick) variable.

Pick either x or y then solve for y or x

  y = -5x/2 -5              solve for y

  x = (-2/5) (y +5)        solve for x

Answer:

They sold 30 adult tickets and 50 kids tickets.

Step-by-step explanation:

This question is solved by a system of equations.

I am going to say that:

x is the number of adult tickets sold

y is the number of kids tickets sold.

80 tickets are sold

This means that [tex]x + y = 80[/tex], or also, [tex]x = 80 - y[/tex]

For a Saturday matinee, adult tickets cost $7.50 and kids under 12 pay only $6.00. Tickets were sold for a total of $525.

This means that:

[tex]7.5x + 6y = 525[/tex]

Since [tex]x = 80 - y[/tex]

[tex]7.5(80 - y) + 6y = 525[/tex]

[tex]600 - 7.5y + 6y = 525[/tex]

[tex]1.5y = 75[/tex]

[tex]y = \frac{75}{1.5} = 50[/tex]

[tex]x = 80 - y = 80 - 50 = 30[/tex]

They sold 30 adult tickets and 50 kids tickets.
