Use the graph of y=e^x to evaluate the expression e^1.5. Round the solurion to the nearest tenth if necessary.

Answers

Answer:

$e^(1.5)=4.482$

Step-by-step explanation:

Given: $f(x)=e^x$

We need to find the value of function at x=1.5

Put x=1.5 into f(x)

$f(1.5)=e^(1.5)$

$f(1.5)=4.482$

Now we will verify the result using graph.

First we draw the graph of f(x) and a vertical line x=1.5

Please see the attachment for graph.

Hence, The value of $e^(1.5)=4.482$

According to my graphing calculator, e^1.5=4.5 which is rounded to the nearest tenth.

The area of this rectangle is 80ft^2. What is the length and width.Width: X+16
Length: X

What is X for Width?
What is X for Length?

Answers

area=LW
80=area
L=x+16
W=x
80=(x+16)(x)
80=x^2+16x
minus 80
0=x^2+16x-80
factor
0=(x-4)(x+20)
set to zero
x-4=0
x=4

x+20=0
x=-20, false since you can't have negative degrees (except in trig)

x=4

legnth=4+16=20 ft

width=4ft

x=4
legnth=20ft
width=4ft
