Step-by-step explanation:
Answer:
V'(4) = 48 mm³/mm
V'(4) means that the rate of change of volume with respect to side when the length of the side is 4 mm
Step-by-step explanation:
Data provided in the question
V is the volume of the cube with x as its sides
Also,
Volume of cube = side³
thus,
V = x³ mm³
Now,
Derivative of volume with respect to side x,
=
or
= V'(x) = 3x²
now,
at x = 4 mm
V'(4) = 3(4)²
or
V'(4) = 48 mm³/mm
Here, V'(4) means that the rate of change of volume with respect to side when the length of the side is 4 mm
First, you must observe the figure and realize that you have a parallelogram and a rectangle.
Therefore, the total area will be the sum of the area of the parallelogram plus the area of the rectangle.
Palelogram area:
A1 = b * h
We have then
b = root ((- 4 - (- 10)) ^ 2+ (2-2) ^ 2) = 6
h = root ((- 7 - (- 7)) ^ 2+ (3-2) ^ 2) = 1
A1 = (6) * (1) = 6 units ^ 2
Rectangle area
A2 = L * W
We have then:
L = root ((1 - (- 2)) ^ 2 + (- 3 - (- 4)) ^ 2) = 3.16227766
W = root ((- 4 - (- 2)) ^ 2+ (2 - (- 4)) ^ 2) = 6.32455532
A2 = (3.16227766) * (6.32455532)
A2 = 20 units ^ 2
The total area is the sum of both ares:
A = A1 + A2
A = 6 + 20
A = 26 units ^ 2
Answer:
the area of this figure
A = 26 units ^ 2
None of these couples are solutions, (11, 3)(11, 3); (−1, −6)(−1, −6); (−3, 3)(−3, 3); <span>(7, 0). Perhaps the choice of answer are insufficient. we can add (1, 48) the couple (7, 0) and (7, 0)(1, 48) is a true answer, why? because it verifies the equation.</span>
Answer:
$150
Step-by-step explanation:
discount=60%
let the price=x
(100-60)% of x=$60
40% of x=60
x=60×(100/40)=150
