The inverse of the function f(x) = 1/2x + 10 is shown.

4 0

Take the f(x) and replace with y to get

y = .5x + 10.

Then flip the y and x to find the inverse.

x = .5y + 10

Now solve for the new y..

x - 10 = .5y

2x - 20 = y.

The missing value is 20.

Pani would pay $59 if she gets a discount of $3 on each shirt and $3 on each jeans

Step-by-step explanation:

Given

Price of shirt = $12

Price of jeans = $19

Price of shirt after $3 discount = 12-3 = $9

Price of jeans after 3 discount = 19-3 = $16

The total money Pani has to pay will be:

$9(3)+16(2)\\=27+32\\=\$59$

Pani would pay $59 if she gets a discount of $3 on each shirt and $3 on each jeans

Answer:

$-\frac{15}{16}$

Step-by-step explanation:

$\frac{1}{4} ^{2}$ = $\frac{1}{16}$

2*(pq)= 2( $\frac{1}{6}$ )= $\frac{1}{3}$

-3 $q^{2}$ = -3 $(\frac{4}{9} )$ = $-\frac{4}{3}$

$\frac{1}{16} +\frac{1}{3}-\frac{4}{3}$ =

$\frac{1}{16} -1$ =

$-\frac{15}{16}$

Pls asap... use trigonometry to find the area of a regular 20- gon with each side = 6 in

Answer:

Area of polygon[20 sides] = 1,140 inch² (Approx.)

Step-by-step explanation:

Given;

Number of sides = 20 sides

Length of each side = 6 inch

Find:

Area of polygon[20 sides]

Computation:

Perimeter of polygon[20sides] = 20 x Length of each side

Perimeter of polygon[20sides] = 20 x 6

Perimeter of polygon[20sides] = 120 inch

Apothem[Shortest distance from center] = S / 2tan[180/n]

Apothem[Shortest distance from center] = 6 / 2tan[180/20]

Apothem[Shortest distance from center] = 6 / 2tan[9]

Apothem[Shortest distance from center] = 18.94

Apothem[Shortest distance from center] = 19 inch (Approx.)

Area of polygon[20 sides] = [Perimeter x Apothem] / 2

Area of polygon[20 sides] = [120 x 19] / 2

Area of polygon[20 sides] = 1,140 inch² (Approx.)
