5.2.4 A P E X Math (coin problem) Equations:

Coin Value Formula:
V(t)=P(1 + r)^t

Coin A: V(t)=25(1 + r)^t
Coin B: V(t)=40(1 + r)^t

In this function, if the value of “r” were to increase, with the value represented by “P” also increase or stay the same? Why? Explain your answer using terms such as “rate of growth” and “initial value” in the context of the coin problem.

(I only need an explanation for the question I typed above, I included images to provide more context.)

The slope of a line is –2 and its y-intercept is (0, 3). what is the equation of the line that is parallel to the first line and passes through (2, 2)? a. 2x + y = 6 b. y = –2x + 3 c.y=1/2x +6 d.y=-2x-6

Stefano accidentally dropped his sunglasses off the edge of a canyon as he was looking down. the height, h(t), in meters (as it relates to sea level), of the sunglasses after t seconds, is shown in the table. during its descent, the pair of sunglasses passed by a climber in the canyon 6 seconds after stefano dropped them. to the nearest meter, what is difference in elevation between stefano and the climber? 166 meters 176 meters 230 meters 240 meters its b.176 i took the test 166 is wrong and 176 is correct

50 points~ ! i have to turn this in tomarrow
