Answer:
the correct answers are 22 and 8
Answer:
56x6+3x
Step-by-step explanation:
3x+7x(8x5)
3x+56x6
If A=38x-x^2 then
dA/dx=38-2x
d2A/dx2=-2
Since the acceleration, d2A/dx2 is a constant negative, when velocity, dA/dx=0, it will be an absolute maximum for A(x)
dA/dx=0 only when 38=2x, x=19
A(19)=38(19)-19^2
A(19)=722-361
A(19)=361 ft^2
So the maximum possible area is 361 ft^2
(This will always be true as the maximum possible area enclosed by a given amount of material will always be a perfect square...)
Answer:
y = - 5/2x - 23/2
Step-by-step explanation:
b = y - (slope)(x)
b = -4 - (-5/2)(-3)
b = -4 - 15/2 = - 23/2
y = -5/2x - 23/2
Answer:
see below
Step-by-step explanation:
1.)
(0, 4)
(1, 7)
y = 3x + b
(4) = 3(0) + b
b = 4
y = 3x + 4
Rate of change: 3 initial value: 4
2.)
(0, -5)
(1, -3)
y = 2x + b
(-5) = 2(0) + b
b = -5
Rate of change: 2 initial value: -5
