The velocity function of a car is given by v(t) = -3t^2 + 18t + 9 m/s. Find the acceleration of the car three seconds before it comes to a stop.
A. a = -6.46 m/s²
B. a = -2.76 m/s²
C. a = -0.46 m/s²
D. a = 2.76 m/s²
The acceleration of the car three seconds before it comes to a stop is 0m/s²
Given the velocity function expressed as v(t) = -3t^2 + 18t + 9
Acceleration is the change in velocity of a body with respect to time.
a(t) = dv/dt
Differentiating the velocity with respect to time will give;
dv/dt = -6t + 18
a = -6t + 18
a = -3(6) + 18
a = -18 + 18
a = 0m/s²
Hence the acceleration of the car three seconds before it comes to a stop is 0m/s²

What is the equation of the line which is perpendicular to y = 2x + 2 and passes through the point (0, 6)?
Step-by-step explanation:
the slope of a line function is always the factor of x.
in our case : 2
it is the ratio y/x indicating how many units y changes, when x changes a certain amount of units.
in our case (2 = 2/1) y increases by 2 for every x increase by 1.
now, the perpendicular slope simply changes x and y upside-down and flips the sign.
in our case it is : -1/2
so, the line function looks like
y = (-1/2)x + b
b is the y-intercept, and we get it by using the coordinates of the point as x and y
6 = (-1/2)×0 + b = b
the full line equation is
y = (-1/2)x + 6

A small start-up skateboard company projects that the cost per month of manufacturing x skateboards will be C(x)=30x+600, and the revenue per month from selling x skateboards will be r(x)=−x2+80x. Given that profit is revenue minus cost, for what value(s) of x will the company break even or make a profit?
9514 1404 393
Answer:
20 ≤ x ≤ 30
Step-by-step explanation:
The profit function is ...
profit = revenue - cost
= (-x^2 +80x) -(30x +600)
= -x^2 +50x -600
= -(x -20)(x -30)
The profit function will be positive where the signs of the factors are different: for x-values between 20 and 30. The profit function will be zero for x=20 and x=30.
The company will break even or make a profit for values of x that satisfy ...
20 ≤ x ≤ 30

What is the value of x in the triangle below?
Answer:
15 cm
Step-by-step explanation:
All of the triangles in this figure are similar 30°-60°-90° triangles.
The ratio of shortest to longest sides in a 30°-60°-90° triangle is 1 : 2. This means the longest side of the largest triangle has length ...
2 × (10 cm) = 20 cm
It also means the shortest side of the smallest triangle is (10 cm)/2 = 5 cm.
The length shown as 'x' is the difference of these measures:
x = 20 cm -5 cm
x = 15 cm
__
Additional comment
There are several "geometric mean" relations that apply to this sort of right-triangle geometry. One of them is that the side marked as 10 cm is the geometric mean of the short segment and the whole segment of the bottom edge. This will confirm that x = 15 cm.
(10 cm)² = (5 cm)(5 +15) cm = 100 cm²

The length of a rectangular book is 2 times its width. The perimeter of the book is 42 inches. Write a system of
equations to represent the dimensions of the book then find the length and width.
Answer:
Mark me as brainlist
Step-by-step explanation:
P = Perimeter
L = Length
W = Width
Perimeter of rectangle = L + L + W + W
or P = 2L + 2W
You know:
P = 36 inches
L = 2W [length is(=) 2 times it's width]
W = ?
P = 2L + 2W
Substitute/plug in what you know, plug in 2W for L since L = 2W
36 = 2(2W) + 2W Simplify
36 = 4W + 2W
36 = 6W Divide 6 on both sides
6 = W Now that you know the width, you can find the length:
L = 2W
L = 2(6)
L = 12
L = 12 in
W = 6 in
PROOF
P = 2(12) + 2(6)
P = 24 + 12
P = 36
