D
E
F
To find surface area, You find the area of every face and add them together(which F shows), but you can also do little shortcuts when there is multiple faces that are the same( like in E and F).

REWARDING BRAINLY TO CORRECT ANSWER

pshichka [43]

Answer:

B. 24

Step-by-step explanation:

The way to find range is by putting the set from largest to smallest, then subtracting the highest number from the lowest. In this case, the highest number would be 31, and the lowest would be 7. So 31-7=24 which is your range. Hope this helps! (please give brainlist!) :)

Which of the following angles is coterminal with 480°

Shtirlitz [24]

480⁰= 360⁰+120⁰
or
480⁰-360⁰=120⁰
You need to remove all 360 angles, sometimes it can be more than one in it.

Coterminal angle is 120⁰.

Derivative Rule [Product Rule]: $\displaystyle \frac{d}{dx} [f(x)g(x)]=f'(x)g(x) + g'(x)f(x)$

Step-by-step explanation:

Step 1: Define

$\displaystyle l = 10 \ meters$

$\displaystyle \frac{dl}{dt} = 4 \ m/day$

$\displaystyle w = 23 \ meters$

$\displaystyle \frac{dw}{dt} = 1 \ m/day$

Step 2: Differentiate

[Area of Rectangle] Product Rule: $\displaystyle \frac{dA}{dt} = l\frac{dw}{dt} + w\frac{dl}{dt}$

Step 3: Solve

[Rate] Substitute in variables [Derivative]: $\displaystyle \frac{dA}{dt} = (10 \ m)(1 \ m/day) + (23 \ m)(4 \ m/day)$
[Rate] Multiply: $\displaystyle \frac{dA}{dt} = 10 \ m^2/day + 92 \ m^2/day$
[Rate] Add: $\displaystyle \frac{dA}{dt} = 102 \ m^2/day$
