With 8 percent increase each year the Sutton family's condo's worth in 8 years will be $216000.
What is exponential function?An exponential function is a mathematical function in the form f(x) = ax, where {x} is a variable and {a} is a constant which is called the base.
Given is that Condos in Georgetown go up in value by 10% each year. Sutton family's condo's current worth is $120,000.
We can write the function to calculate the worth after {T} years as follows.
A{T, R} = A{I} {1 + RT}
A{T, R} = {120000} {1 + (10/100) x 8}
A{T, R} = {120000} {1 + 0.1 x 8}
A{T, R} = {120000} {1 + 0.8}
A{T, R} = {120000 x 1.8}
A{T, R} = 216000

Answer: length of EF is 18 units.
Step-by-step explanation:
similar triangles (as displayed in the photo) have the same angle measures, but can have different side lengths. however, these side lengths are proportional to each other, meaning that with similar triangles, there will ALWAYS be a number you can multiply the first triangle by to get its similar triangle.
you can find this number by dividing one side length of whichever triangle is bigger with its corresponding side on the other triangle (for example, sides DF and AC correspond, so you'd divide whichever value's bigger by the smaller one. in this case you'd divide 21 by 14.) this gives you 1.5, which tells you that triangle DEF is 1.5 times larger than triangle ABC. so to get EF, just multiply BC (which is 12) by 1.5. this gives you 18. so, EF equals 18. hope this helped :3
When it was raining, Elliott drove for 120 miles. When the rain stopped, he drove
20 mph faster than he did while it was raining. He drove for 300 miles after the
rain stopped. If Elliott drove for a total of 10 hours, how fast did he drive while it
was raining?
Answers
Answer:
[tex]\boxed{22}.[/tex]
Step-by-step explanation:
Since Elliott drove for a total of 10 hours, and he drove for 120 miles while it was raining and 300 miles after the rain stopped, we know that he drove for a total of 120 + 300 = <<120+300=420>>420 miles.
If he drove for a total of 10 hours and covered a distance of 420 miles, then his average speed was 420 miles / 10 hours = <<420/10=42>>42 mph.
Since Elliott drove 20 mph faster after the rain stopped than he did while it was raining, then we know that his speed while it was raining was 20 mph slower than his average speed of 42 mph. That means his speed while it was raining was 42 mph - 20 mph = <<42-20=22>>22 mph.

Are isosceles triangles always 90?
Answers
No, isosceles triangles do not always have to have 90-degree angles.
An isosceles triangle is a triangle with two sides of equal length. While the two sides are equal, they can be of any length. This means that the angles of the isosceles triangle can vary, and the triangle does not always have to have 90-degree angles. In fact, an isosceles triangle can have angles that range from 0 to 180 degrees. The only requirement for an isosceles triangle is that it must have two sides of equal length. As such, an isosceles triangle can have angles that are greater than 90 degrees, angles that are less than 90 degrees, or even angles that are equal to 90 degrees.

1. Cost of a paperback = 25 cents = $0.25
Cost of a hardcover book = $1.25
There were 54 paperbacks and 163 hardcover books sold.
Money library raised = (0.25 × 54) + (1.25 × 163) = $217.25
2. Cost for round trip airfare = $398.60
Cost of room per night = $115.70
Cost of room for two nights = 2 × $115.70 = $231.40
Cab fare from airport to hotel = $40.00
Total fare from airport to hotel and the return = 2 × $40.00 = $80.00
Total cost = $398.60 + $231.40 + $80.00 = $710
3. Total working hour of Paula = 48 hours
Earning for first 35 hours = $14.50/h × 35

You're playing a game of pool and it's your turn, but you have no direct shots. To make any shot, you will need to bank the cue ball (the white ball) off the side of the table before it hits your ball.
That means that you hit the cue ball so that it bounces off the side and then hits your colored ball, moving it in the direction of a pocket (hole). The angle that the ball hits the bumper is equal to the angle that it bounces off the bumper.
The cue ball is 18 inches from the top bumper (side of pool table) and 50 inches from the right bumper. The dimensions of the pool table are 96 inches in the horizontal direction by 46 inches in the vertical direction
Answers
By Solving this proportion will give you the value of the angle you need to aim your shot.
What is angle of elevation ?
angle elevation can be defined as the angle formed between line of sight and horizontal line.
Draw a diagram of the pool table, labeling the dimensions of the table and the position of the cue ball.
Since the cue ball is 18 inches from the top bumper and 50 inches from the right bumper, you can draw a right triangle with these side lengths.
The dimensions of the pool table can also be used to draw a right triangle, with the horizontal dimension (96 inches) as the base and the vertical dimension (46 inches) as the height.
These two triangles are similar because they are both right triangles and they share a right angle. Therefore, the ratios of their sides are equal.
You can use the ratios of the sides of these triangles to determine the angle at which you should aim your shot. To do this, you can set up a proportion using the corresponding sides of the two triangles. For example, you could use the ratio of the base to the height of the small triangle (18 inches to 50 inches) and set it equal to the ratio of the base to the height of the large triangle (96 inches to 46 inches).
Hence, by Solving this proportion will give you the value of the angle you need to aim your shot.

Given an inscribed angle of 48°, you want to know the measure of the central angle that subtends the same arc.
Inscribed angleThe measure of an inscribed angle is half the measure of the arc it subtends.
∠LMP = 1/2(arc LP)
48° = 1/2(arc LP) . . . . . . use the given value
96° = arc LP . . . . . . . . . multiply by 2
Central angleThe measure of an arc of a circle is the same as the measure of the central angle it subtends: the arc measure and its central angle measure are identical.
arc LP = ∠LOP
96° = ∠LOP
__
Additional comment
That's a long way of saying the central angle is twice the inscribed angle that subtends the same arc. ∠LOP = 2×∠LMP.
he cost per pound of chicken is $2. Each serving of chicken is about 4 oz. What will be the portion cost of the chicken
Answers
The unit price of the portion of the chicken will be $0.50.
To find the portion cost of the chicken, we need to know how much it costs per ounce, and then multiply that by the number of ounces in a serving.
We can begin by calculating the cost per ounce of chicken by dividing the cost per pound by the number of ounces in a pound:
$2 (cost per pound) ÷ 16 (ounces per pound) = $0.125 (cost per ounce)
Now that we know the cost per ounce, we can find the portion cost of the chicken by multiplying it by the number of ounces in a serving:
$0.125 (cost per ounce) × 4 (ounces per serving) = $0.50
So the portion cost of the chicken is $0.50 . So the answer is
C. $0.50.

PLEASE HELP ME FILL OUT NUMBER 2 I DID THE OTHER QUESTIONS FOR YOU TO USE
1) The Magnolia trees purchased for planting at the school are 3 feet tall. Research shows that these types of trees grow at an average rate of 3/4 foot per year.
a) Write an equation in Slope-Intercept form to represent the growth of the trees over time. Let x represent the number of years and let y represent the height (in ft.) of the tree.
Y=3/4x+3
b) What does the y-intercept represent in your equation
Stands for feet Y=3
c) Determine the height of the tree in 3 years.
Y=3/4×3+3=9/4+3=21/4=5.25 feet
2. Could the equation 3x - 4y = - 12 be used to represent the same information in question #1? Explain your reasoning
a) What does the 3 and the 4 in this equation tell us?
b) Using this equation can you tell me how tall the tree will be in 24 years?
c) Using the equation find the x-intercept. What does this mean in this problem?
Answers
1)
a) The equation Y=3/4x+3 can be used to represent the growth of the trees over time.
b) The y-intercept in this equation represents the starting height of the trees, which is 3 feet.
c) In 3 years, the height of the trees will be 5.25 feet according to the equation.
2)
No, the equation 3x - 4y = -12 cannot be used to represent the same information in question #1. This equation is not in slope-intercept form, which is necessary to represent a linear relationship between two variables.
a) The 3 and the 4 in this equation are coefficients of the variables x and y, respectively. They do not represent any specific value or quantity in the context of the problem.
b) It is not possible to determine the height of the tree in 24 years using this equation because it is not in the correct form.
c) To find the x-intercept, we can set y to 0 and solve for x. This gives us x = -3. The x-intercept in this equation represents the number of years at which the height of the tree is 0 feet. This does not have any meaning in the context of the problem.
a) The y-intercept in the equation, represented by the constant 3, stands for the initial height of the trees when they are planted (3 feet tall). The slope of the line, represented by the coefficient of x (3/4), represents the average rate of growth of the trees over time (3/4 foot per year).
b) In 3 years, the height of the trees can be found by substituting 3 for x in the equation and solving for y: Y=3/4*3+3=9/4+3=21/4=5.25 feet.
The equation 3x - 4y = - 12 cannot be used to represent the same information in question #1 because it is not in slope-intercept form. In order to be in slope-intercept form, the equation must have the form y = mx + b, where m represents the slope and b represents the y-intercept.
a) The 3 and 4 in the equation 3x - 4y = - 12 represent the coefficients of the x and y terms, respectively. They do not represent the initial height or the rate of growth of the trees.
b) It is not possible to determine the height of the trees in 24 years using the equation 3x - 4y = - 12 because it is not in the correct form.
c) The x-intercept of the equation 3x - 4y = - 12 can be found by setting y equal to 0 and solving for x: 0 = 3x - 4y, so x = - 4y/3. This means that the x-coordinate of the point where the line intersects the x-axis is - 4y/3. This has no meaning in the context of this problem, as the x-axis represents the number of years and the y-axis represents the height of the trees.

How many real solutions does the system X² y² 25 and ay 10 have?
Answers
The system X² y² 25 and ay 10 has no real solutions.
To solve this system, we need to solve each equation for y.
For the first equation, X² y² 25, we can divide both sides by X² to get:
y² = 25/X²
Then, take the square root of both sides to get:
y = ± √(25/X²)
For the second equation, ay = 10, we can divide both sides by a to get:
y = 10/a
To find out if the system has real solutions, we need to compare the two equations. Since the two equations are not equal, the system has no real solutions.
