We want to solve the two equations
e^{x}=6
and
4^{y+3}=3

First equation.
Take natural log of each side.
ln(e^{x})=ln(6)\\xln(e)=ln(6)\\
x=ln(6)=1.7918
Note that ln(e) = 1 by definition.
Answer: x = 1.79 (nearest hundredth)

Second equation.
Take natural log of each side.
ln(4^{y+3})=ln(3)\\
(y+3)ln(4)=ln(3)\\
y+3= \frac{ln(3)}{ln(4)} =0.7925\\y=0.7925-3=-2.2075
Answer: y = -2.21 (nearest hundredth)

F(13)=45,000(0.9)^13
Nadusha1986 [10]

Answer:

About 879.877

Step-by-step explanation:

To find f,

f(13) = 45,000(0.9)^13

13f = 45,000(0.25418658283)

13f = 11438.3962274

f = 879.877

Please tell me I did this the right way, Thanks!

What are the coordinates of the hole in the graph of the function f(x) ?
Vinvika [58]
ANSWER

(3, \infty )

EXPLANATION

The given function is

f(x) = \frac{ {x}^{2} - 9}{x - 3}

When we plug in x=3 into this function, we obtain,

f(3) = \frac{0}{0}

This means that the function is discontinuous at x=3.

We need to simplify the function to obtain,

f(x) = \frac{(x - 3)(x + 3)}{(x - 3)}

This implies that,

f(x) = x + 3

The graph this function is a straight line that is continuous everywhere.

To graph

f(x) = \frac{ {x}^{2} - 9}{x - 3}
we draw the graph of

f(x) = x + 3
and leave a hole at x=3.

See diagram in attachment.

Hence the coordinates of hole is

(3, \infty )
