For the function f(t)+Pe^rt, if P = 8 and r = 0.08, then what is the value of f(8) to the nearest tenth?

Bogdan [553]

F(t) = P.e^(r.t) [ and not as you wrote it f(t)+Pe^rt]
plug in:

f(t) = 8.e^(0.08t) (where e = 2.718 and t=8 given, f(8))
f(8) = 8.(2.718)^(0.08*8) = 21.74^(0.64)

f(8) = 7.17

What is the slope of the line that passes thought the points (-7,-7)and(-7,1) write your answer in simplest form.

Alexxandr [17]

Answer:

The slope is undefined

Step-by-step explanation:

Find slope by using the slope formula, $m=\frac{y2-y1}{x2-x1}$

Use the given points and insert the x's and y's to solve for slope

(-7, -7) (-7, 1)

$m=\frac{y2-y1}{x2-x1}$

$m=\frac{1-(-7)}{-7-(-7)}$

$m= \frac{8}{0}$

m = undefined

The slope for the given point is undefined because it is impossible to divide a number by 0

2. JI. has coordinates J(-6, 1) and Z(-4, 3). Find the coordinates of the midpoint.

AleksandrR [38]

Answer:

(- 5, 2 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( $\frac{x_{1}+x_{2} }{2}$ , $\frac{y_{1}+y_{2} }{2}$ )

Here (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (- 4, 3) thus

midpoint = $\frac{-6-4}{2}$ , $\frac{1+3}{2}$ ) = ( $\frac{-10}{2}$ , $\frac{4}{2}$ ) = (- 5, 2 )
