Scarlett is trying to find the height of a dam. she stands 90 meters away from the dam and records the angle of elevation to the top of the dam to be 26º.
scarlett's height is 1.65 meters, so the height of the dam is ?
meters.

45.55 m to the nearest hundredth.

Step-by-step explanation:

tan 26 = opposite / adjacent side = h / 90   where h = height of the dam - Scarlett's height.

The height of the dam =

y = 90 tan 26

= 43.895 m

Now we need to add Scarlett's height  

= 45.55 m.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
