write the equation in standard form for the circle with center (5,0) passing through (5, 9/2)
The equation in standard form for the circle with center (5,0) passing through (5, 9/2) is 4x² + 4y² - 40x + 19 = 0
Calculating the equation of the circleGiven that
Center = (5, 0)
Point on the circle = (5. 9/2)
The equation of a circle can be expressed as
(x - a)² + (y - b)² = r²
Where
Center = (a, b)
Radius = r
So, we have
(x - 5)² + (y - 0)² = r²
Calculating the radius, we have
(5 - 5)² + (9/2 - 0)² = r²
Evaluate
r = 9/2
So, we have
(x - 5)² + (y - 0)² = (9/2)²
Expand
x² - 10x + 25 + y² = 81/4
Multiply through by 4
4x² - 40x + 100 + 4y² = 81
So, we have
4x² + 4y² - 40x + 19 = 0
Hence, the equation is 4x² + 4y² - 40x + 19 = 0

Matthew wants to take out a loan to buy a car. He calculates that he can make repayments of $35,000 per year. If he can get a six-year loan with an interest rate of 9.25%, what is the maximum price he can pay for the car?
The maximum price Matthew can pay for the car, considering his repayment capability and the loan terms, is approximately $126,318.29.
To determine the maximum price Matthew can pay for the car, we need to consider his repayment capability and the terms of the loan.
Matthew can make annual repayments of $35,000. Since the loan term is six years, the total amount he can repay over the loan period is $35,000 multiplied by six, which equals $210,000.
To calculate the maximum price of the car, we need to account for the interest rate of 9.25%. The interest rate represents the cost of borrowing and is applied to the loan amount.
Let's assume the loan amount is denoted by P.
The formula to calculate the future value of a loan with interest is:
FV = P(1 + r)^n
Where:
FV = Future value (total amount repaid)
P = Principal amount (maximum price of the car)
r = Interest rate per period (9.25% or 0.0925)
n = Number of periods (six years)
Since Matthew can repay a total of $210,000 over the loan period, we can set up the equation:
$210,000 = P(1 + 0.0925)^6
Now we can solve for P:
P = $210,000 / (1 + 0.0925)^6
Evaluating this expression, we find:
P ≈ $126,318.29
Therefore, the maximum price Matthew can pay for the car, considering his repayment capability and the loan terms, is approximately $126,318.29.

If f (x) = 7+2x and g(x) =5x -2, find f (7)
Answer:f=103.444
Step-by-step explanation:
took this test and got an A++
The value of the function \(f(x)=7+2x\) for \(f(7)\) is 21.
The given functions are \(f(x)=7+2x\) and \(g(x)=5x-2\).
Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
To find \(f(7)\), substitute \(x=7\) in \(f(x)=7+2x\), we get
\(f(7)=7+2(7)\)
\(f(7)=21\)
Therefore, the value of the function \(f(x)=7+2x\) for \(f(7)\) is 21.

A boys age is three times the age of his sister. Their ages together total 16 years. What’s is the age of each
Answer: Boy: 48, Sister: 16
Step-by-step explanation:
You could write a system of equations... x represents the boy and y represents the sister.
x = 3y
x+y=16
You can use substitution. Replace the x in the second equation with 3y since they have the same value.
(3y)+y=16
4y=16
y=16
Now, you can plug y into either equation. I'll use the first one.
x= 3(16)
x= 48

an electric water heater consumes 5 kw for 2 hours per day. what is the cost of running it for one month (30 days) if electricity costs 12 cents/kw.h?
The cost of running the electric water heater for one month (30 days) would be $36, assuming the electricity costs 12 cents per kilowatt-hour.
To calculate the cost of running the electric water heater for one month, we need to determine the total energy consumption and multiply it by the cost per kilowatt-hour.
The water heater consumes 5 kW for 2 hours per day, so the daily energy consumption can be calculated as follows:
Daily energy consumption = Power (kW) × Time (hours) = 5 kW × 2 hours = 10 kWh
Next, we calculate the total energy consumption for one month (30 days):
Total energy consumption = Daily energy consumption × Number of days = 10 kWh/day × 30 days = 300 kWh
Finally, we multiply the total energy consumption by the cost per kilowatt-hour (12 cents/kWh) to find the cost of running the water heater for one month:
Cost = Total energy consumption × Cost per kilowatt-hour = 300 kWh × $0.12/kWh = $36

The cone-shaped paper cup in Problem 2 is only half filled with water. So, the height of the water is 6cm and a diameter of the top surface of the water of 4cm. Calculate the volume of water. Use 3.14 for the value of pi.
The volume of water in the cone-shaped paper cup is 25.12 cubic centimeters.
To calculate the volume of water in the cone-shaped paper cup, we can use the formula for the volume of a cone:
V = (1/3) * π * r^2 * h
Given:
Height of water (h) = 6 cm
Diameter of the top surface of water (2r) = 4 cm
First, we need to find the radius (r) of the top surface of the water. Since the diameter is given as 4 cm, the radius is half of that:
r = 4 cm / 2 = 2 cm
Now we can substitute the values into the volume formula and calculate the volume of water:
V = (1/3) * 3.14 * (2 cm)^2 * 6 cm
V = (1/3) * 3.14 * 4 cm^2 * 6 cm
V = (1/3) * 3.14 * 24 cm^3
V = 25.12 cm^3.

Two cylinders are shown below. Which cylinder has the greater volume? Use 3.14 for π. Round to the nearest hundredth. Use the drop-down menus to show your answer
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
To find which cylinder has the greater volume, we need to find out the volume of each one.
As we all know that the formula used to determine the volume of a cylinder is:
V = The base area*the height
<=> V = π\(r^{2}\)h (cubic units)
For example, in my attached photo, we will use this formula to find the volume of each one.
1. Cylinder A:The base area = π\(r^{2}\) = π\(3.5^{2}\) = 38.46 square in
The height = 8.5 in
=> the volume of Cylinder A
= The base area*the height
= 38.46*8.5
= 326.91 cubic in
2. Cylinder B:The base area = π\(r^{2}\) = π\(2.7^{2}\) = 22.89 square in
The height = 11 in
=> the volume of Cylinder A
= The base area*the height
= 22.89*11
= 251.79 cubic in
Hence, Cylinder B has the greater volume

Isaac works in the school cafeteria. He is packing boxed lunches into crates for students to take on a field trip. The crates are shaped like cubes and have a volume of one cubic foot each. The crates are packed in a van that is shaped like a rectangular prism. The van has a volume of 150 cubic feet. The floor of the van is completely covered by a layer of 30 crates. The height of the van that is filled is ___ feet.
The filled van has a height of 4 feet, indicating the vertical dimension from the floor to the top of the crates inside.
To determine the height of the van that is filled with crates, we need to consider the volume of the crates and the total volume of the van.
Given that each crate has a volume of one cubic foot, and there are 30 crates covering the floor of the van, the total volume occupied by these crates is 30 cubic feet.
Now, to find the remaining volume inside the van, we subtract the volume of the crates from the total volume of the van. The van has a volume of 150 cubic feet, and we have already accounted for 30 cubic feet occupied by the crates.
Remaining volume inside the van = Total volume of the van - Volume occupied by the crates
Remaining volume = 150 cubic feet - 30 cubic feet
Remaining volume = 120 cubic feet
Since the van is shaped like a rectangular prism, the height of the van represents the vertical dimension.
To find the height of the van, we divide the remaining volume by the area of the van's base. The base area can be found by dividing the remaining volume by the length and width of the van.
Given that the van is completely filled with crates, the base area is equal to the area of 30 crates.
Base area = Volume occupied by the crates / Height
Base area = 30 cubic feet / Height
Now, we can solve for the height:
Height = Volume of the remaining space / Base area
Height = 120 cubic feet / 30 cubic feet
Height = 4 feet
Therefore, the height of the van that is filled with crates is 4 feet.
