Answer:
B. $63.19
Step-by-step explanation:
You will pay $63.19 for a item with original price of $78.99 when discounted 20%. In this example, if you buy an item at $78.99 with 20% discount, you will pay 78.99 - 15.798 = 63.19 dollars.
The horizontal distance from the base of the skyscraper to the ship is 870 feet.
Data;
- Angle of Depression = 45°
- Observation Deck = 870 feet
<h3>Horizontal Distance </h3>
To calculate the horizontal distance from the base of the skyscraper, we can use trigonometric ratio SOHCAHTOA here;
Since we have the value of angle and opposite, we can calculate the adjacent using tangent of the angle.
![Tan \theta = \frac{opposite}{adjacent}](https://tex.z-dn.net/?f=Tan%20%5Ctheta%20%3D%20%5Cfrac%7Bopposite%7D%7Badjacent%7D)
Let's substitute the values and solve
![Tan 45 = \frac{870}{x} \\x = \frac{870}{tan 45} \\x = 870 ft](https://tex.z-dn.net/?f=Tan%2045%20%3D%20%5Cfrac%7B870%7D%7Bx%7D%20%5C%5Cx%20%3D%20%5Cfrac%7B870%7D%7Btan%2045%7D%20%5C%5Cx%20%3D%20870%20ft)
The horizontal distance from the base of the skyscraper to the ship is 870 feet.

Answer: $49,305.56
Step-by-step explanation:
A(t)=a(1+r)^t (its subtraction if the thing decreases)
A(t)=amount after t time periods
t=number of time periods
a=initial amount
r=rate of growth (can’t be a percent, change by moving two decimal places)
A(t)=32000(1+0.155)^3
