Answer:

f(-1) = -22

Step-by-step explanation:

f(x): 2x^3 - 3x^2 + 7x - 10

Repace x = -1

f(-1) = 2(-1)^3 - 3(-1)^2 + 7(-1) - 10

f(-1) = -2 - 3 - 7 - 10

f(-1) = -22

Answer:

694 ft²

Step-by-step explanation:

Calculate the area of all 6 walls, noting that the front and back faces are congruent as are the 2 side faces and top/bottom faces

area = 2(13 × 8.5) + 2(11 × 8.5) + 2(13 × 11)

= 221 + 187 + 286 = 694 ft²

Distance Formula: $\displaystyle d = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}$

Step-by-step explanation:

Step 1: Define

Find endpoints from graph

Point (-3, -3)

Point (4, 2)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(4- -3)^2+(2- -3)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{7^2+5^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{49+25}$
[√Radical] Add: $\displaystyle d = \sqrt{74}$
