The unit rate here is how much the bike will cost for a day. Looking at the equation, we see the cost per day is $0.50. So, the unit rate is $0.50 per day.

What is the factored form of x2 - 6x – 16?

liraira [26]

The factored form is (x - 8)(x + 2).

(x - 8)(x + 2)
x^2 + 2x - 8x - 16
x^2 - 6x - 16

An inelastic collision occurs between a large truck and smaller sedan. Calculate the final velocity of the objects and explain t

k0ka [10]

The final velocity is 15.8 m/s in the forward direction

Step-by-step explanation:

An inelastic collision occurs when the two object after the collision stick together.

In any case, the total momentum of the system is conserved before and after the collision, in absence of external forces. Therefore, we can write:

$p_i = p_f\\m u + MU = (m+M)v$

where in this problem:

m = 1300 kg is the mass of the small sedan

u = 20 m/s is the initial velocity of the small sedan

M = 7100 kg is the mass of the truck

U = 15 m/s is the initial velocity of the truck

v is the final combined velocity of the small sedan + truck

Here we have taken both the velocity of the sedan and the truck in the positive (forward) direction

Solving the equation for v, we find the final velocity:

$v=\frac{mu+MU}{m+M}=\frac{(1300)(20)+(7100)(15)}{1300+7100}=15.8 m/s$

And since the sign is positive, this means that is direction is the same as the initial direction of the sedan and the truck, so forward.

At which values of x does the function F(x) have a vertical asymptote? Check all that apply.

Anton [14]

You get vertical asymptotes because the x-value causes you to try to divide by 0.

If you look at the denominator, the x-values of 0, 1, and -5 all will make the denominator equal to 0, making the whole function explode.

You find these by solving 3x(x-1)(x+5)=0.

That's your answer: 0, 1, and -5

Given that the heights and the volumes of the two solids are equivalent, find the diameter of the cylinder. Round your answer to

VLD [36.1K]

We use the definition of the volumes of each figure in order to calculate the diameter of the cylinder. We calculate as follows:

V(cylinder) = V(rectangular prism)
πr²h = lwh

from the given, height of the cylinder = height of the prism

πr² = lw
πr² = 5.3(2.7)
r = 2.13

D=2r = 4.27 mm
