Answer:
Thus the surface area of this cylinder involving pie is:
ft²
or
ft²
Step-by-step explanation:
Given
radius = r = 10 ft
height = h = 15 ft
The surface area of a cylinder formula is:
substituting the value = r = 10 ft and h = 15 ft
ft²
Thus the surface area of this cylinder involving pie is:
ft²
or
ft²
<span>2w(4w^2 - 2w) + 3w(-2w^2 + 8w)
First distribute 2w and 3w(you do this by multiplying them to all values inside the parentheses):
</span>8w^3 - 4w^2 - 6w^3 + 24w^2
Now simplify by adding/subtracting like terms:
8w^3 - 6w^3 = 2w^3
-4w^2 + 24w^2 = 20w^2
So we have:
2w^3 + 20w^2
Answer:
idk if it's right and i'm really sorry if it isn't
∴ x=
Step-by-step explanation:
f(x)=3
fx=3
÷f on both sides
x=
Answer:
1. Not proportional
2. Proportional
3. Proportional
4. Not proportional
Step-by-step explanation:
A trick I used was to divide 3 by 7 and I got around 0.42.
Then I proceeded to type the fractions into the calculator to see which ones gave me 0.42.
Example: 12 divided by 28 is equal to about 0.42 so it is <u>proportional</u>
24 divided by 54 is not 0.42 so it is <u>not proportional</u>
B)
E = mc^2
E = 7 * 5^2
E = 7 * 25
E = 175
c)
b = sqrt (c/d)
b = sqrt (100/4)
b = sqrt (25)
b = 5
