To find the total area of this figure, you have to find the area of each of the separate figures and then add those 2 answers together. Your work should look like this:

2 x 2 = 4

8 x 8 = 64

64 + 4 = 68

Your answer should be 68 ft.^2

A boat is located a sea level. A scuba diver is 80 feet along the surface of the water from the boat and 30 feet below thw water

Sauron [17]

Given :

A boat is located a sea level. A scuba diver is 80 feet along the surface of the water from the boat and 30 feet below the water surface.

A fish is 20 feet along the horizontal plane from the scuba diver and 10 feet below the scuba diver.

To Find :

The slope between the scuba diver and fish.

Solution :

Horizontal distance between diver and fish is 20 feet.

Fish is 10 feet below the scuba diver.

Slope between scuba diver and fish is :

$tan\ \theta = \dfrac{10}{20}\\\\tan\ \theta = 0.5$

Therefore, the slope between the scuba diver and fish is 0.5 .

Luis wants to buy a skateboard that usually sells for $135. At big AL's they are discounted 20%. What is the total cost of the s

tino4ka555 [31]

Answer:

117.99

Step-by-step explanation:

First step is to find the discount

Discount = original price * discount rate

= 135 * 20%

= 135*.20

=27

Take the discount from the original price and that is the new price

new price = original price - discount

= 135-27

=108

Now we need to find the tax

tax = new price * tax rate

= 108 * 9.25%

= 108 * .0925

=9.99

The final price is the new price plus the tax

final price = new price + tax

= 108+9.99

=117.99

What is the relationship between exponentials and logarithms? How can you use these to solve equations? Provide an example in yo

Sveta_85 [38]

Answer:

Exponentials and logarithms are inverses of each other.

Step-by-step explanation:

Exponentials and logarithms are inverses of each other.

For logarithmic function:

Domain = $\left ( 0,\infty \right )$ , Range = $\left ( -\infty ,\infty \right )$

Vertical asymptote is y - axis.

x - intercept is (1,0)

For exponential function:

Domain = $\left ( -\infty ,\infty \right )$ , Range = $\left ( 0,\infty \right )$

Horizontal asymptote is x - axis.

y- intercept is (0,1)

Both exponential and logarithmic functions are increasing.

For example:

Solve: $\log x=\frac{\log 5+\log 3}{\log 3^2}$

$\log x=\frac{\log 5+\log 3}{\log 3^2}\\\log x=\frac{\log (5\times 3)}{2\log 3}\,\,\left \{ \because \log (ab)=\log a+\log b\,,\,\log a^b=b\log a \right \}\\=\frac{\log 15}{2\log 3}$

$\Rightarrow \log x=\frac{\log 15}{2\log 3}\\\Rightarrow x=e^{\frac{\log 15}{2\log 3}}\,\,\left \{ \because \log x=y\Rightarrow x=e^y \right \}$
