What is the equation of the circle with center (3.2, -2.1) and radius 4.3?
A. (x+2.1)^2 + (y-3.2)^2 = 8.6
B. (x-3.2)^2 + (y+2.1)^2 = (4.3)^2
C. (x+3.2)^2 + (y-2.1)^2 = 4.3
D. (x-2.1)^2 - (y+3.2)^2 = (4.3)^2
Thus, (x+3.2)2+(y+2.1)2=18.49 ( x + 3.2 ) 2 + ( y + 2.1 ) 2 = 18.49 is the equation of the circle with the center at (−3.2,−2.1) and a radius of r=4.3 .
What is circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.
here, we have,
the centre and radius of a circle are known,
we have to determine its equation:
Use the formula (x a) 2 + (y b) 2 = r 2 to determine a circle's equation when you are aware of its radius and centre. Here, stands for the circle's centre, and is its radius. This equation is essentially a variant way of writing the general equation for a circle.
(x - h)2+ (y - k)2 = r2 is the formula for the equation of a circle, where (h, k) stands for the circle's center's coordinates and r for the radius.
We know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius.

long, 4 inches wide, and 5 inches high.
Answer:
V = 160 cubic inches
Step-by-step explanation:
Given that,
Length, width and height of prism are 8 inches, 4 inches and 5 inches
The formula for the volume of a rectangular prism is given by :
[tex]V=l\times b\times h\\\\V=8\times 4\times 5\\\\V=160\ inches^3[/tex]
So, the volume of the prism is 160 cubic inches.

Step-by-step explanation:
1: You will pay $682.5 for a item with original price of $1050 when discounted 35%. In this example, if you buy an item at $1050 with 35% discount, you will pay 1050 - 367.5 = 682.5 dollars.
2: You will pay $617.5 for a item with original price of $650 when discounted 5%. In this example, if you buy an item at $650 with 5% discount, you will pay 650 - 32.5 = 617.5 dollars.

Answer:
[tex]f^{-1}[/tex] (22) = 7
Step-by-step explanation:
The inverse function maps the output of the function back to its input
f(7) = 22 means when input is 7 the output is 22
The inverse maps the output 22 back to the input 7 , that is
[tex]f^{-1}[/tex] (22) = 7

Which number line shows the solution to inequality 3x – 3 < 12?
Answer:
A
Step-by-step explanation:
The Graph "A" show the value of x in inequality 3x – 3 < 12
What is inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
What does open circle and close circle shows in graph?A closed circle indicates "greater than or equal to" or "less than or equal to," while and open circle indicates "greater than" or "less than".
According to the question
Given inequality 3x – 3 < 12
Solving for x
3x – 3 < 12
3x < 12 + 3
3x < 15
x < 5
Open circle will be used to show the greater than sign
Therefore,
Graph A shows the inequality .
Hence, the Graph "A" show the value of x in inequality 3x – 3 < 12

The formula
C = 9f + 4p + 4c
gives the number of calories C in a serving of food that contains f grams of fat, p grams of protein, and c grams of carbohydrate.†
Find the number of grams of protein in an 8-ounce serving of vanilla yogurt that contains 179 calories, 3 g of fat, and 31 g of carbohydrate.
g
Answer:
7 grams of protein
Step-by-step explanation:
C = 9f + 4p + 4c
Plug the given information into the given formula
179 = 9(3) + 4p + 4(31)
Use PEMDAS
179 = 27 + 4p + 124
Combine like terms
179 = 151 + 4p
Subtract both sides by 151 to isolate variable p
179 - 151 = 4p
28 = 4p
Divide both sides by 4 to isolate variable p
28 ÷ 4 = p
7 = p

On wends day 72% of the customers who bought gas at the gas station made additional purchases.There were 250 customers who bought gas. How many of the 250 customers made additional purchases
Answer:
A = 180 customers.
Step-by-step explanation:
Let the number of customers that made additional purchases be A.
Given the following data;
Percentage = 72% = 72/100 = 0.72
Total number of customers = 250
To find the number of customers that made additional purchases;
A = 0.72 * 250
A = 180 customers.
Therefore, 180 customers made additional purchases on Wednesday.

A shelf is in the shape of a triangle. Find the angles of the triangle if the measures of the angles are in the ratio 1:2:5 and Classify it.
Answer:
22.5deg, 45deg, 112.5deg, an obtuse triangle.
Step-by-step explanation:
The sum of angles is 180deg.
If they're in the ratio of 1:2:5, one angle is 1/(1+2+5)=1/8 of 180deg, the others are 2/8 and 5/8, so:
Smallest angle is 180deg * 1/8 = 22.5deg
Second is 180deg * 2/8 = 45deg
Third is 180deg * 5/8 = 112.5deg
it's an obtuse triangle, as it has an angle over 90deg
