Answer: Function rule: F(L)=4L+8 Area: 96
Step-by-step explanation: Basically, if the length is 4 more than the width, that means the length is 12. Now, to get area you multiply length times width. So, 12 times 8 equals 96.
Hope this helps :)
Answer:
169/100
Step-by-step explanation:
93 + 76/100 = 169/100
Answer:
h = 3 cm
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = bh ( b is the base and h the height )
Here A = 7 = ← expressed as an improper fraction
and b = 5 = , thus
× × h = , that is
h =
Multiply both sides by 8 to clear the fractions
21h = 63 ( divide both sides by 21 )
h = 3
Take the derivative:
g’(x) = 12x^3 - 24x^2
Set equal to zero and solve:
0 = 12x^3 - 24x^2
0 = 12x^2 (x - 2)
x = 0 or x = 2
Plug back into original
g(0) = 3(0^4) - 8(0^3)
g(0) = 0 - 0
g(0) = 0
g(2) = 3(2^2) - 8(2^3)
g(2) = 3(4) - 8(8)
g(2) = 12 - 64
g(2) = -52
There is an absolute max at (0,0) or when x = 0
Answer:
15
Step-by-step explanation:
Cross multiply to get 25x = 375
Divide each side by 25 to get x = 15
