For the function f(t) =Pe^rt , if P= 7 and r= 0.07 then what is the value of f(7) to the nearest tenth?

White raven [17]

Answer:

A. 11.4

Step-by-step explanation:

$f(t) = P e^{rt}$

Data:

P = 7

r = 0.07

Calculation:

$\begin{array}{rcl}f(t) & = &Pe^{rt}\\f(7)& = & 7 e^{(0.07 \times 7)}\\ & = & 7 e^{0.49}\\& \approx & 7 \times 1.632\\ & \approx & \mathbf{11.4}\\\end{array}$

write an equation for the line that passes through the point (8,3) and parallel to -4x+8y=23. Use slope-intercept form.

kvasek [131]

(1/2)x+b=y because the equation that given the slope is 1/2 if you leave y alone and take the x’s number

put the point now , 4+b=3 so b is -1

the equation is (1/2)x-1=y
