The equation of the circle centered at (1, 3) with a radius of 4 units is:
(x - 1)^2 + (y - 3)^2 = 16
How to write the equation of a circle?For a circle with the center on the point (a, b) and radius R, the equation is:
(x- a)^2 + (y - b)^2 = R^2
In this case, the center is (1, 3) and the radius is R = 4, so the equation will be, so we just replace these in the general equation that we have above.
(x - 1)^2 + (y - 3)^2 = 4^2
(x - 1)^2 + (y - 3)^2 = 16

Three times the sum of a number and 5 is 7.
Use the variable C for the unknown number.
Answer:
3(C + 5) = 7
Step-by-step explanation:
Let C = unknown number
The sum of a number and 5:
C + 5
Three times the sum of a number and 5:
3(C + 5)
Three times the sum of a number and 5 is 7:
3(C + 5) = 7
To solve
Use the distributive law: a(b + c) = ab + ac
⇒ 3C + 15 = 7
Subtract 15 from both sides:
⇒ 3C = -8
Divide both sides by 3:
⇒ C = -8/3
So
The expression is

Two students each write a function, C(n), that they think can be used to find the number of circles needed to make the nth figure in the pattern shown.
Use the drop-down menus to explain why each function does or does not represent the number of circles needed to make the nth figure in the pattern.
The function that can be find used to find the number of circles needed to make the nth figure in the sequence is (C + 1) + 4.
How to calculate the sequence?The sequence can be illustrated through the function (C + 1) + 4 where C is the previous number. For the third picture, the number of circles will be:
= (C + 1) + 4
= 5 + 4
= 9
The fourth term will be:
= 9 + 4
= 13
Therefore, each figure uses 4 circles more than the previous one.

Find the missing number if the average is 8.8 and _____
A) 4
B) 8
C) 12
D) none of the above
Answer:
none of the above
Step-by-step explanation:
Let us call x the smallest integer. Because the next two numbers are consecutive even integers, we can call represent them as x + 2 and x + 4. We are told the sum of x, x+2, and x+4 is equal to 72.
x + (x + 2) + (x + 4) = 72
3x + 6 = 72
3x = 66
x = 22.
This means that the integers are 22, 24, and 26. The question asks us for the product of these numbers, which is 22(24)(26) = 13728.
The answer is 13728.

Chase deposits $6,604.80 into a savings account that pays a simple annual interest rate of 3.22%. How much interest will he earn after 4 years?
SHOW WORK and will give brainlist.
Answer:
$850.69824
Step-by-step explanation:
simple interest formula : (principal * rate of interest * time)/100(6,604.80 * 3.22 * 4)/100$850.69824Answer:
$850.70 (nearest cent)
Step-by-step explanation:
Simple interest formula: A = P(1 + rt)
where:
A = final amountP = principal (initial balance)r = annual interest rate (in decimal form)t = time (in years)Given:
P = $6,604.80r = 3.22% = 0.0322t = 4 yearsSubstituting given values into the formula, and solving to find A:
⇒ A = 6604.8(1 + 0.0322 · 4)
= 6604.8(1.1288)
= $7455.50 (nearest cent)
Therefore, to find the amount of interest earned, subtract the principal from the final amount:
⇒ I = A - P
= 7455.50 - 6604.80
= $850.70 (nearest cent)

Calculate the slopes of all four sides of EFGH. Use these slopes to prove that EFGH is a rectangle.
Answer:
The slope of both EF and GH are 2/3
The slope of both FG and EH are -3/2
You can see that these slopes are perpendicular, forming a rectangle
Step-by-step explanation:
To find slope use the slope formula: y1 - y2 / x1 - x2

If f(x) is an exponential function where f(-2) = 25 and f(7) = 85, then find the
value of f(14), to the nearest hundredth.
=
Exponential from two points
The exponential function f(x) can represent growth or decay
The value of f(14) is 226.07
How to determine the value of f(14)?The given parameters are:
f(-2) = 25 and f(7) = 85
An exponential function is represented as:
f(x) = ab^x
So, we have:
ab^-2 = 25
Also, we have:
ab^7 = 85
Divide both equations.
This gives
b^9 = 3.4
Take the 9th root of both sides
b = 1.15
Recall that:
ab^7 = 85
This gives
a* 1.15^7 = 85
Solve for a
a = 31.95
So, the exponential function is:
f(x) = 31.95 * 1.15^x
Substitute 14 for x
f(14) = 31.95 * 1.15^14
f(14) = 226.07
Hence, the value of f(14) is 226.07
