Answer:

C)28in

Step-by-step explanation:

To get the area of this face, we will divide it into 3 sections.

Area of the 1st section:

Given:

l=4in

w=2in

Formula:

a=l*w

Solution:

a=l*w

a=8in^2

Area of the 2nd section:

Given:

l=2in

w=2in

Formula:

a=l*w

Solution:

a=l*w

a=2in*2in

a=4in^2

Area of the 3rd section:

l=8in

w=2in

Formula:

a=l*w

Solution:

a=l*w

a=8in*2in

a=16in^2

a1+a2+a3=Area of the face

8in^2+4in^2+16in^2=28in^2

Hope this helps ;) ❤❤❤

What is mode and rang

abruzzese [7]

Answer:

The mode is the number that is repeated most often, but all the numbers in this list appear only once, so there is no mode. The largest value in the list is 7, the smallest is 1, and their difference is 6, so the range is 6.

KatRina [158]

If a large pizza cost 15 dollars and the medium pizza is 9 dollars.Since the pizza parlor sold only 5 large pizzas, then… 15 x 5 = 75Deduct this from the total amount of pizza sold…$291 - $75 = $216So, the pizza parlor sold a total of $216 for the medium pizzas. Divide this to the amount of one medium pizza. $216 / 9 = 24.So the pizza parlor sold a total of 24 medium pizzas.

Find the x-intercept of a porabola with a vertex of (-3,-14) and y-intercept (0,-13)

mina [271]

Answer:

see explanation

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

here (h, k) = (- 3, - 14), thus

y = a(x + 3)² - 14

To find a substitute (0, - 13) into the equation

- 13 = 9a - 14 ( add 14 to both sides )

9a = 1 ( divide both sides by 9 )

a = $\frac{1}{9}$ , hence

y = $\frac{1}{9}$ (x + 3)² - 14 ← equation of parabola

To find the x- intercepts let y = 0

$\frac{1}{9}$ (x + 3)² - 14 = 0

Multiply through by 9

(x + 3)² - 126 = 0 ( add 126 to both sides )

(x + 3)² = 126 ( take the square root of both sides )

x + 3 = ± $\sqrt{126}$ = ± 3 $\sqrt{14}$

Subtract 3 from both sides

x = - 3 ± 3 $\sqrt{14}$

The x- intercepts are therefore

x = - 3 - 3 $\sqrt{14}$ ≈ - 14.22 ( to 2 dec. places ) or

x = - 3 + 3 $\sqrt{14}$ ≈ 8.22 ( to 2 dec. places )
