Answer:

The pole is 6 feet tall.

Step-by-step explanation:

The height makes the perpendicular and the shadow makes the base of the triangle in the given question

                                Pole                       Mary

Height                         x                            4

Shadows                    15                           10

If the height is taken along y- axis and shadow is taken along x axis

Then

tan alpha = Perpendicular/ base

for Mary    Tan alpha = 4/10

For the pole = tan alpha = x/15

Comparing      x/15= 4/10

x= 4*15/10= 60/10= 6

The pole is 6 feet tall.

The table shows the relationship between the amount of money (y) remaining in Maddy's money box and the number of months (x): Fu
algol13
Maddie :
(1,100),(2,80)
slope (rate of change) = (80 - 100) / (2 - 1) = -20/1 = -20

Caitlin :
y = -18x + 120......slope (rate of change) = -18

To determine which rate of change is greater, take the absolute value of the slopes.
 Maddy : | -20 | = 20
Caitlin : | -18 | = 18
 the greater rate of change is the one with the larger absolute value....so that would be Maddy...function 1 shows a greater rate of change because Maddie spends 20 each month and Caitlin spends 18 each month
