The answer is D. 1 sq ft = 1 ft x 1 ft = 12 in x 12 in 1 sq ft = 144 sq in 5 sq ft = 144 * 5 = 720 sq in.

Evaluate (x)=3+1=3x+ 1over the domain {1,2,3,4,} . What is the range of<br> (x)

katrin [286]

Answer: Step-by-step explanation:

Step-by-step explanation:

The range of a function is the set of images associated with a given domains. As domain is a discrete set, the range can be determined by evaluating the function at each element in domain:

x = 0

x = 1

x = 2

x = 3

The range of r(x) is .

There are 120 children there are twice as many boys than girls how many girls are there?

PolarNik [594]

Boys are b
Girls are g

b + g = 120
2g = b

Substitute the second equation into the first

2g + g = 120
3g = 120
g = 40

Plug in g = 40 and solve for b

b + g = 40
b + 40 = 120
b = 80

There are 40 girls and 80 boys.

What force would have been applied to the bus from t=16 s to t=21 s? Assume the mass of the bus was 50 kg.

Svetllana [295]

Applying Newton's Second Law, it is found that the force, in Newtons, is given by:

$F = 10[v(21) - v(16)]$

Newton's Second Law states that Force, in Newtons, is <u>mass times acceleration</u>, that is:

$F = ma$

In this problem, mass of 50 kg, thus $m = 50$

Acceleration is <u>change in velocity divided by change in time</u>, that is:

$a = \frac{\Delta_v}{\Delta_t}$

In this problem, we don't know the velocities, but know that time is from 16s to 21s, thus:

$\Delta_t = 21 - 16 = 5$

$\Delta_v = v(21) - v(16)$

Thus, the force is given by:

$F = ma$

$F = m\frac{\Delta_v}{\Delta_t}$

$F = 50\frac{[v(21) - v(16)]}{5}$

$F = 10[v(21) - v(16)]$
