Answer:

$17,535

Step-by-step explanation:

Original (old) salary: $16,700/year

+ raise: 0.05($16,700/year) = $835/year

---------------------------------------------------------------------------------

New salary: Original salary plus amount of raise:

$16,700/year + $835/year = $17,535

A faster but still valid approach to finding the new salary involves multiplying the original salary by 1.05:

1.05($16,700) = $17,535. Here the '1.00' represents the original salary and the '0.05) the raise.

A car is driving away from a crosswalk. The formula d = t2 + 2t expresses the car's distance from the crosswalk in feet, d, in t

alukav5142 [94]

Answer:

8 feet per second.

Step-by-step explanation:

We have been given that a car is driving away from a crosswalk. The formula $d=t^2+2t$ expresses the car's distance from the crosswalk in feet, d, in terms of the number of seconds, t, since the car started moving.

We will use average change formula to solve our given problem.

$\text{Average change}=\frac{f(b)-f(a)}{b-a}$

$\text{Average change}=\frac{d(5)-d(1)}{5-1}$

$\text{Average change}=\frac{(5)^2+2(5)-((1)^2+2(1))}{4}$

$\text{Average change}=\frac{25+10-(1+2)}{4}$

$\text{Average change}=\frac{35-3}{4}\\\\\text{Average change}=\frac{32}{4}\\\\\text{Average change}=8$

Therefore, the the car's average speed over the given interval of time would be 8 feet per second.

Task: Population of a Species

Cloud [144]

Answer:

C(t) = 20t

Step-by-step explanation:

The graph of C(t) appears to be linear

The y intercept is 0

The slope is 200/10 = 20

y = mx+b where m is the slope and b is the y intercept

y = 20x+0

y = 20x

C(t) = 20t

A cube has a surface area of 384 square inches. What is the edge lenth of the cube? Explain pls

m_a_m_a [10]

Since there are 6 sides to a cube we can divide the total surface area by 6 to find the area of a single side

384 / 6 = 64

since the side of a cube is a square the sides are the same length, so we need a number, that when multiplied by itself is 64. The answer is 8

A. Yes

B. Because the three inside angles of both triangles would be identical.

C. Set up a ratio:

121/22 = AB/30

Solve for AB:

AB = (121 * 30) / 22

AB = 3630 / 22

AB = 165 ft.
