Answer:

Ф = 19.80 °

Step-by-step explanation:

by using pythagoras theorem

h² = p² + b²

13² = 5² + b ²

b = √194

b = 13.93

now

tanФ = p/b

Ф = tan¬1( 5 / 13.93)

Ф = 19.80 °

Given the function f(x) = 4^x - 1, explain and show how to find the average rate of change between x = 1 and x = 4.

soldier1979 [14.2K]

Answer:

Step-by-step explanation:

f(1)=4^1 - 1 = 3

f(4) = 4^4 - 1 = 255

rate of change = $\frac{f(x_2)-f(x_1)}{x_2-x_1}$

(255 - 3) / (4 - 1) = 252 / 3 = 84

Am trying to find the value of r<br> 1/r + 2/1-r = 4/r^2

Mashcka [7]

<span>1/r + 2/1-r = 4/r^2

1-r+2r/r(1-r)=4/r^2
(1+r)/r(1-r)=4/r^2 cancle r both side

1+r/1-r=4/r

cross multiply
r+r^2=4-4r
r^2+4r+r-4=0
r^2+5r-4=0
r^2+4r+r-4=0
solve it for r factor it...
