Answer:
B. BC=12, FH=9
Step-by-step explanation:
I guessed and it was right
5x + 10y = 360
y = 2x + 1
5x + 10*(2x + 1) = 360
5x + 20x + 10 = 360
25x = 350
x = 14
y = 2x + 1
y = 2*14 + 1
y = 29
Derek has 14 nickels and 29 dimes
Answer:
5 people times $10=50
$50-$34.15=15.85
15.85 divided by 5 people. Equals $3.17
Answer:
3.17?
Answer:
The critical points of the function
f(x) = 2x(4 - x)³
are x = (1, 4)
Step-by-step explanation:
Given the function
f(x) = 2x(4 - x)³
To find the critical points, we differentiate f(x) to obtain f'(x), and then find the zeros of the resulting quadratic function.
Now, differentiate f(x).
f'(x) = 2(4 - x)³ + 2x(-1)×3(4 - x)²
= 2(4 - x)³ - 6x(4 - x)²
= 2(4 - x)²(4 - x- 3x)
= 2(4 - x)²(4 - 4x)
f'(x) = 8(4 - x)²(1 - x)
Now we set f'(x) = 0 and solve
8(4 - x)²(1 - x) = 0
=> 8(1 - x) = 0
=> 1 - x = 0
=> x = 1
Or
(4 - x)² = 0
x = 4 twice.
So x = (1, 4)
Therefore, the critical points are x = (1, 4)
