Using relations in a right triangle, it is found that
The height of the tree is of 91.6 meters.
The graph for this problem is given at the end of the answer.
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.From the diagram graphed, we can build two relations involving the tangent of the angles, as follows:
From the smaller right triangle:
tan(43º) = h/x
0.9325 = h/x
x = (1/0.9325)h.
x = 1.0724h (we want to find h, hence we write x as a function of h).
From the larger right triangle:
tan(38º) = h/(x + 19).
tan(38º) = h/(1.0724h + 19).
0.7813 = h/(1.0724h + 19).
Applying cross multiplication:
h = 0.7813(1.0724h + 19).
h = 0.8379h + 14.8447.
0.1621h = 14.8447
h = 14.8447/0.1621
h = 91.6 meters.
The height of the tree is of 91.6 meters.

What is the total amount that Benjamin has made in payments over the 7
months?
Answers
If Benjamin's credit card has an APR of 19%, calculated on the previous monthly balance, and a minimum payment of 2%, starting the month after the first purchase. the total amount that Benjamin has made in payments over the 7 months is: $285.01.
Total amount made in paymentTo determine the total amount that Benjamin has made in payments over the 7 months we would need to add up or sum up all the Payment Finance received charges for the first six months.
Now let calculate the total amount that Benjamin made in payment.
Hence,
Total amount made in payment=$48.00+$47.80+$47.60+$47.40+$47.20+$47.01
Total amount made in payment =$285.01
Therefore if Benjamin's credit card has an APR of 19%, calculated on the previous monthly balance, and a minimum payment of 2%, starting the month after the first purchase. the total amount that Benjamin has made in payments over the 7 months is: $285.01.

Evaluate g(x)=x−13 over the domain {2,4,6,8}. What is the range of g(x)?
Answers
The range of the function is {-11, -9, -7, -5}.
The given function is g(x)=x−13.
We need to find the range of g(x).
What is the range and domain of the function?The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.
Now, put x=2,4,6,8 in the given function and find the range of function.
So, g(2)=2−13=-11

4- start: 45 end:20
5-start: 30 end: 60

1 - there will be increase of 233.33 % , 2 - there will be increase of 122.22 % , 3 - there will be decrease of 15 % , 4 - there will be decrease of 55.56 % , 5 - there will be increase of 100%
WHAT IS PERCENTAGE ?% is a relative number that is used to represent hundredths of any quantity. Since one percent (1%) equals one tenth of something, 100 percent denotes the entire amount, and 200 percent denotes twice the amount mentioned percentage.
CALCULATION1 - Start : 3 end : 10
formula for finding percentage increase is = [tex]\frac{end - start }{start } * 100[/tex]
so substituting value in the formula ;
that is equal to = [tex]\frac{10-3}{3} * 100[/tex]
= [tex]\frac{7}{3} * 100[/tex]
= 233.33% increase
2 - Start : 9 End : 20
directly substituting the values in the above mentioned formula
= [tex]\frac{20-9}{9} * 100[/tex]
= [tex]\frac{11}{9} * 100[/tex]
= 122.22% increase
3 - Start : 100 end : 85
plugging in the values = [tex]\frac{85-100}{100}*100[/tex]
= [tex]\frac{-15}{100} * 100[/tex]
= -15% i.e. decrease of 15%
4 - Start : 45 end : 20
putting in the values = [tex]\frac{20-45}{45} * 100[/tex]
= [tex]\frac{-25}{45}*100[/tex]
= -55.56% i.e. decrease of 55.56 %
5 - Start : 30 end : 60
putting in the values = [tex]\frac{60-30}{30}* 100[/tex]
= [tex]\frac{30}{30} * 100[/tex]

she is finished. Write and solve a linear equation to find the total number of pages
months.

Answers
Answer:
f(x) = 12x+35
f(5) = 95 pages written at 5 months
Step-by-step explanation:
Step 1: write the slope intercept equation
f(x) = mx+b
f(x) = the value of the equation at month x
m = slope of the linear equation (pages written PER month)
x = the month
b = intercept of the equation (pages already written)
Step 2: relate given information to the variables
m = 12 pages per month
b = 35 pages already written
Step 3: update equation
f(x) = 12x+35
Step 4: solve for x = 5 months
f(5) = 12(5) + 35 = 60 + 35 = 95

The formula for calculating Alex's earnings from his employment at the theme park is 8(40 x 9 + 100) = 8(360 + 100) = 8(460) = $3,680.
Given: that the plane ticket costs $2,200 and that y = 11.5x gives the function that represents the potential earnings Alex may make from the tech internship, the inequality that reflects the maximum number of hours Alex can work at the internship follows.
He puts in 20 hours every week at the internship, which translates to 160 hours of work over the course of 8 weeks.
Given that the internship pays $11.5 an hour for 160 hours, her earnings of 11.5 x 160 = $1,840 will not be sufficient to cover the cost of the plane ticket.
A few of the theme park employment that are available in this sector include costume character work, ride technician, admissions attendant, lifeguard, and gaming attendant. Workers at concession stands must be swift to prevent long queues and receive cash for food and drinks.

The quadratic function is defined as follows:
- 2 / 3 x² + 7 / 3 x + 8
How to find quadratic function?The quadratic function has the following sets of values below:
(0,8) (2,10) (3,1).
The quadratic function is represented as follows:
f(x) = ax² + bx + c
using (0,8)
8 = a(0)² + b(0) + c
8 = c
Therefore, using (2, 10)(3 , 1).
f(x) = ax² + bx + c
10 = a(2)² + b(2) + 8
10 - 8 = 4a + 2b
2 = 4a + 2b
1 = 2a + b
1 = a(3)² + b(3) + 8
1 = 9a + 3b
Hence, combine the equations,
2a + b = 1
9a + 3b = 1
multiply equation(i) by 3
6a + 3b = 3
9a + 3b = 1
3a = - 2
a = - 2 / 3
Therefore,
9a + 3b = 1
9(- 2 / 3) + 3b = 1
-6 + 3b = 1
3b = 7
b = 7 / 3

The world's supply of helium is finite. There are approximately 35 billion cubic meters of helium on Earth, and every year humans consume about 210 million cubic meters of it. Let stand for the volume (in millions of cubic meters) of helium remaining, and stand for the number of years since 2018. Which of the following linear equations could model the decreasing supply of helium
Answers
The equation which correctly models the decreasing supply of helium as described in the task content is; y = 35 - 0.21x.
Which equation correct models the decreasing supply of helium?It follows from the task content that the equation which correctly models the decreasing supply of helium according to the description is to be determined.
Let, y = amount of helium remaining.
Let x = no of years since 2018.
First, one must convert 210 million to billion cubic feets as follows;
210 million = (210/1000) billion.
= 0.21 billion cubic meters per year.
The number above represents the rate of change of the linear model, otherwise termed the slope.
On this note, since the starting deposit of helium in 2018 was; 35 billion.
This insinuates that the y-coordinate of the y-intercept of the required model is; 35.
Hence, the required decreasing Linear model for the supply of helium is;
y = 35 - 0.21x.
The equation above follows from the slope-intercept form of a linear equation.
