Answer:
{5, -3} {0, -1/3}
Step-by-step explanation:
For the first problem, they all have a GCF of 2, so you divide it all by 2 to get x^2-2x-15=0. Now, we need two factors of -15 that equal -2. Those are -5 and 3. Our new equation is x^2-5x+3x-15. To factor, the GCF of x^2 and 5x is x, so divide by x and you get x(x-5). The GCF of 3x and 15 is 3, so divide by 3 and you get 3(x-5). Now, put the numbers outside of the parenthesis into their own, and you get (x+3)(x-5). To get to 0, for the first one x has to be -3, and for the second, x has to be 5.
For the second, 12x^2 and 4x have a GCF of 4x. Since this we don't have a c value, we just divide and factor like this: 4x(3x+1). Since 4x is outside the parenthesis but we don't have any other terms outside, x=0 because 4(0) is 0. To cancel out 1, our x value inside has to be -1/3, because -1/3*3=-1.

What is the approximate circumference of the circle that has a center at (2, 1) and passes through the point (7, 1)? A 10 units B. 16 units С 31 units D 79 units
Answer:
C. 31 units
Step-by-step explanation:
Circumference of a circle is the distance around the circle and is given by C = pi•d
Your circle with a point and center given has a radius of 5 because from (2,1) to (7,1) is 5 units. Radius 5 means the diameter is 10.
C = pi•10
= 3.14•10
= 31.4 using 3.14 as an approximation for pi.
Circumference is approximately 31 units.

Find the sum of the first 8 terms of the following series, to the nearest integer 48,60,75
The series is a geometric series and the sum of the first 8 terms of the series 48, 60, 75 is 952.32
How to determine the sum of the first 8 terms?The series is given as:
48, 60, 75
The above series is a geometric series with the following parameters:
First term, a = 48
Common ratio, r = 1.25
The sum of n terms is:
[tex]S_n = \frac{a(r^n - 1)}{r -1}[/tex]
So, we have:
[tex]S_8 = \frac{48 * (1.25^8 - 1)}{1.25 -1}[/tex]
Evaluate
[tex]S_8 = 952.32[/tex]

Answer:
Okay so your numbers are:
0, 2, 2, 4, 5, 1, 3, 4, 2, 4, 5, 0, 0, 1, 3, 4
You have to put them in order first:
0, 0, 0, 1, 1, 2, 2, 2, 3, 3, 4, 4, 4, 4, 5, 5
Now that its all in order you have to pull out the middle number.
Since there are 16 numbers its an even pile so you have to get the 2 middle numbers:
2, 3
Add them both together:
2 + 3 = 5
Then divide by 2:

Alan wants to install security cameras in his store, which has dimensions of 30 feet by 30 feet. Each camera can view an area of approximately 112.5 ft2, with a viewing area shaped like a right triangle. How many cameras will be necessary to cover the entire store? . If he places cameras only in the corners of the store, how much area is left uncovered? ft2.
Based on the information given, the area that will be left uncovered will be 450ft².
From the information given, the area of the store roof will be:= 30 × 30 = 900ft²
The area viewed by the camera = 112.5ft²
Therefore, the number of cameras needed will be:
= 900/112.5 = 8
When he places the cameras in the corners of the store, he area covered will be:
= 4 × 112.5 = 450ft²
Therefore, the area left uncovered will be:
= 900 - 450
= 450 ft²

Which lines are perpendicular to 3x – y = 10? Select all that apply. A. y = 3x + 5 B. y = –13x + 17 C. x + 3y = 27 D. y – 2 = 13(3x + 36)
The equation of the line which is perpendicular to 3x - y = 10 is y = -(1/3) x + c. Then the correct option is B.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
The line that is perpendicular to 3x - y = 10.
The equation can be written as
y = 3x - 10
Then the slope of the line will be
m₁ = 3
Let m₂ be the slope of the second line.
The product of the slope of the perpendicular lines is a negative one.
m₁m₂ = -1
3m₂ = -1
m₂ = -1/3
Then the equation of the perpendicular line will be
y = - (1/3)x + c
3y = -x + c
x + 3y = c
where c is the constant.
Thus, the correct option is B.

How to determine the standard equation?From the graph, we have the following parameters:
Center (a,b) = (2,5)Radius, r = 4The equation of the circle is then calculated using:
(x - a)² + (y - b)² = r²
So, we have:
(x - 2)² + (y - 5)² = 4²
