How do you write the equation for 4.

1 answer:

8 0

This is an exponential growth problem of the form:

F=Ir^t, F=final amount, I=initial amount, r=rate, t=time

In this case:

F=50(1.08^t)

F(17)=50(1.08^17)

F(17)=$185.00

Solve for x in the triangle. Round your answer to the nearest tenth. (Please help)

DanielleElmas [232]

Answer:

x = 6.5

Step-by-step explanation:

Since this is a right triangle we can use trig functions

cos theta = adjacent side / hypotenuse

cos 23 = 6/x

x cos 23 / 6

x = 6 /cos 23

x=6.51816

Rounding to the nearest tenth

x = 6.5
