On solving the provided question, we can say that We can use the trigonometry sine to solve for the other side: sin 65 = y/20 => y = 18.126
what is trigonometry?The area of mathematics known as trigonometry examines the correlation between triangle side lengths and angles. The area first appeared in the Hellenistic era, around the third century BC. from the use of geometry in astronomical study.
We can arrange a right triangle with 20 feet as the hypotenuse and 65 degrees as the angle between the hypotenuse and adjacent side assuming that the ground and wall meet at a 90 degree angle. The side across from the angle would be the amount of feet the ladder extends up the wall
We can use the trigonometric function sine to solve for the other side:
sin 65 = y/20
y = sin(65) . 20
y = 18.126

The value of a car is $18,000 and depreciating at a rate of 12% per year. Use
an exponential function to find the value of the car after 10 years.
$5012.02 is the value of the car after 10 years
How to use the exponential function to find the value of the car after 10 years?Depreciation is the reduction in the value of an asset over time
Given that: the present value of a car is $18,000 and it's depreciating at a rate of 12% per year
The exponential function is given as
Y= a ( 1 - r )^t
where a = present value of a car, r = depreciation rate and t = number of years
Y = 18,000 (1-0.12)¹⁰
Y = $ 5012.02
Therefore, the value of the car after 10 years is $ 5012.02

Ted and Mary ordered meals costing a total of $30, including tax. They left an 18% tip. How much did they spend in all?
A $48.00
B $39.00
C $36.40
D $35.40
Answer:
D $35.40
Step-by-step explanation:
We need to find 18% of $30 and then add it to the $30 total.
To find a percent of a number, change the percent to a decimal by moving the decimal point two places to the left. Then multiply it by the number.
18% of $30 =
= 18% * $30
= 0.18 * $30
= $5.40
The tip was $5.40. Now we add the tip to the total.
$30 + $5.40 = $35.40
Answer: D $35.40

Kira drove 522 miles in 9 hours.
At the same rate, how many miles would she drive in 7 hours?
GIven:522 miles in 9 hours.
So if we divide 522 by 9 we get that Kira drives 58 miles per hour.
Now in 7 hours Kira just drives 7 times that which means Kira drives.
58*7=406 miles
Hope this helped!
Step-by-step explanation:
Distance travelled in 9 hours = 522 miles
Distance travelled in 1 hour = 522/9 = 58 miles
Distance travelled in 7 hours = 7 * 58 = 406 miles

Answer:
g(g(x)=25x
Step-by-step explanation:
g(g(x) is a composition function. Think of g(x) as input. That means whatever g(x) equal that will be inside of the function g(x)
g(x) equal 5x so 5x will be the equal value going into the function g(x)
[tex]g(x) = 5x[/tex]
[tex]g(x) = 5(5x)[/tex]
Which equal 25x
So I need help again so here is the question “My mom is baking cookies for a party. The recipe requires 2 eggs for every 4
cups of sugar To have enough cookies for the party, she determined she would
need 12 eggs. If my mom has 25 cups of sugar in the pantry, does she heve
enough sugar to make the cookies”
Answer:
She has enough sugar.
Step-by-step explanation:
Let x = cups of sugar needed
eggs/cups of sugar = 2/4 = 1/2
12 eggs/x = 1/2
24 = x
Since she as 25 cups available and she needs 24 cups, it looks like she has enough sugar with 1 cup left over. I hope she is making chocolate chip cookies.
