Find the equation of the circle with center at (3,-2) and radius of 3.
Answer:
The equation of the circle is (x - 3)² + (y + 2)² = 9
Step-by-step explanation:
The form of the equation of a circle is (x - h)² + (y - k)² = r², where
h is the x-coordinate center of the circlek is the y-coordinate of the center of the circler is the radius of the circle∵ The center of a circle is (3, -2)
∴ x-coordinate of the center is 3
∴ y-coordinate of the center is -2
∴ h = 3 and k = -2
∵ The radius of the circle is 3
∴ r = 3
→ Substitute them in the form of the equation above
∵ (x - 3)² + (y - -2)² = (3)²
∴ (x - 3)² + (y + 2)² = 9
∴ The equation of the circle is (x - 3)² + (y + 2)² = 9
In a cafeteria, 5/8 of the students are eating salads, and 1/4 are eating sandwiches. There are 24 students in the cafeteria. How many students are eating lunches other than salads or sandwiches?
Answer:
Step-by-step explanation:
first, you would want to find the common denominator
3/8 (salads) = 3/8
1/4 (sandwiches) = 2/8
add them together to find out how much students and eating either salads or sandwiches
3/8 + 2/8 = 5/8
this means 5/8 of 24 students are eating either salads or sandwiches
24 students = 24/24 as a fraction
find the common denominator of 5/8 and 24/24
24/24 = 24/24
5/8 = 15/24
the final answer would be that 15 students out of 24 are eating a lunch other than a salad or sandwich
The number of people eating lunches other than salads or sandwiches is 3.
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, In a cafeteria, 5/8 of the students are eating salads, and 1/4 are eating sandwiches.
So, The number of people eating salads is (5/8)×24 = 15.
And the number of people eating sandwiches is (1/4)×24 = 6.
Therefore, The number of people eating lunches other than salads or sandwiches is (24 - 15 - 6) = 3.

Write an equation for the line shown on the graph below.
A: y= 10x
B: y= -10
C: y= 50x
D: y= -50x
Use the following graph to find the slope of the line connecting Saturn and earth
Answer:
The slope is 2.
Step-by-step explanation:
To find the slope we can take two points from the graph (in this example I'll use (3, 2) and (4, 4)) and input them in this expression: [tex]\frac{y2-y1}{x2-x1}[/tex]
[tex]\frac{4-2}{4-3}[/tex]
Solve:
4 - 2 = 2
4 - 3 = 1
[tex]\frac{2}{1}[/tex] = 2
The slope of the line connecting Saturn and Earth is 2.

Natalie wrote a computer program that generates two random numbers from one to 11. When she runs it, what is the probability that both values will be more than 8? Write your probability answer as a fraction.
Answer:
Step-by-step explanation:
There are a lot of ifs in this problem. The generator has to be a fair one. Any one of the 11 numbers must be equally likely to happen. Second, the sequence must not be the same each time she turns it on. Assuming both are true, then the numbers she will get are
9 10 11 for one number
9 10 11 for the other number
P(x>8) = 3/11 * 3/11 = 9/121

Answer:
6.305
Step-by-step explanation:
Given
6 * 10° + 3 * 10^-1 + 5 * 10^-3
Required
Solve the expression
6 * 10° + 3 * 10^-1 + 5 * 10^-3
[Express 10° as 1]
So, we have:
= 6 * 1 + 3 * 10^-1 + 5 * 10^-3
= 6 + 3 * 10^-1 + 5 * 10^-3
Express the exponents as fraction.
= 6 + 3 * ⅒ + 5 * 1/10³
= 6 + 3 * ⅒ + 5 *1/1000
= 6 + 3/10 + 5/1000
Convert fractions to decimals
= 6 + 0.3 + 0.005
= 6.305
Hence, the result of the expression is 6.305

2) The coordinates of the vertices of quadrilateral ABCD are A(-1,8),
B(0,4), C(-2,1), and D(-4,3). Quadrilateral A'B'C'D' is the image of
quadrilateral ABCD after a rotation of 180° about the origin. State the
coordinates of the vertices of A'B'C'D'.
Answer:
The coordinates of vertices of A'B'C'D' are:
A'(1,-8), B'(0,-4), C'(2,-1) and D'(4,-3)
Step-by-step explanation:
When a point (h,k) is roated 180 degrees about the origin it becomes (-h,-k) which means that the new point after rotation is the negative of the previous.
Given vertices are:
A(-1,8), B(0,4), C(-2,1), and D(-4,3)
The new vertices will be:
[tex]A(-1,8) => A'(1,-8)\\B(0,4)=> B'(0,-4)\\C(-2,1)=> C'(2,-1)\\D(-4,3)=> D'(4,-3)[/tex]
The coordinates of vertices of A'B'C'D' are:
A'(1,-8), B'(0,-4), C'(2,-1) and D'(4,-3)
