Given:
Radius of circle = 12 units
Area of sector = 24π sq. units.
Central angle = x
To find:
The value of x.
Solution:
We have,
[tex]r=12[/tex]
[tex]A=24\pi[/tex]
[tex]\theta = x[/tex]
We know that, area of a sector is
[tex]A=\dfrac{\theta }{360^\circ}\pi r^2[/tex]
Where, [tex]\theta[/tex] is central angle, r is radius.
[tex]24\pi=\dfrac{x}{360^\circ}\pi (12)^2[/tex]
[tex]24\pi=\dfrac{x}{360^\circ}\pi (144)[/tex]
[tex]\dfrac{24\pi}{144\pi}=\dfrac{x}{360^\circ}[/tex]
[tex]\dfrac{1}{6}=\dfrac{x}{360^\circ}[/tex]
Multiply both sides by 360 degrees.
[tex]\dfrac{1}{6}\times 360^\circ=x[/tex]
[tex]60^\circ=x[/tex]
The value of x is 60 degrees.
Therefore, the correct option is A.

Deanna knows that the floor in her kitchen is a square with an area of 169 ft2. The perimeter of her kitchen floor is found by adding the lengths of all its sides. What is the perimeter of her kitchen floor? Explain how you found your answer.
Answer:
52 ft
Step-by-step explanation:
area of a square is l x w. all sides are equal so the l = w
A = 169 ft^2 so each side is the square root of 169 which is 13 ft
perimeter of the floor would be all four sides added or length of 1 side multiplied by 4 since they are all equal
Perimeter = 13ft × 4 = 52 ft
so:
Answer:
52m
Step-by-step explanation:
Area of the square floor = 169 m²
For a square with each side 's' , area will be s². Similarly , for a square with area 'a' , length of each side will be √a.So,
Length of each side of floor = √169 = 13m
For a square with each side 's' , its perimeter will be 4s.Hence ,
Perimeter of the kitchen = 13 × 4 = 52m

Answer: -0.5
Step-by-step explanation:
We can see that at x=0 that Y=2, when x=2, y=1, so we do the x1 - x2 = -2 and y1-y2 = 1
Then we do 1 / -2 = -0.5
The average rate of change is -0.5

(a) Use Mtan = lim h->0 [f(a + h) – f(a)] / h
to find the slope of the tangent line mtan = f'(a).
Answer:
Mtan=1-2a
Step-by-step explanation:
Mtan=lim h->0[5-(a+h)-(a+h)^2-(5-a-a^2)/h
=lim h->0[5-a-h-a^2-2ah-h^2-5+a+a^2]/h
=lim h->0[h-2ah-h^2+5-5-a+a-a^2+a^2]/h
=lim h->[h-2ah-h^2 +0+0+0]/h
=lim h->o[h(1-2a-h)/h
=lim h->0 (1-2a-h)
=1-2a-0
=1-2a
Mtan=1-2a.

A rectangular prism with a volume of 5x + 13x² + 6x cubic units has a base area of x² + 2x square units. Find the height of the rectangular prism.
The height of the prism is units.
(Simplify your answer)
Answer:
h = 5x + 3
Step-by-step explanation:
I believe the volume should be [tex]5x^{3} + 13x^{2} + 6x[/tex] in the question. Based on the correction:
[tex]V = 5x^{3} + 13x^{2} + 6x\\A = x^{2} + 2x\\V = A.h\\h = \frac{V}{A} = \frac{5x^{3} + 13x^{2} + 6x}{x^{2} + 2x} = \frac{x(5x^{2}+13x+6}{x(x+2)}=\frac{5x^{2}+13x+6}{x+2} = \frac{(x+2)(5x+3)}{x+2} = 5x+3[/tex]

Help me out the meaning
slope intercept form:
y = mx + b
m = slope
b = y-intercept
the y-intercept is the place on the y-axis (vertical) where the line crosses. In this problem, the line crosses at (0,4), meaning the y-intercept is 4.
y = mx + 4
the slope is technically the rate of change (rise over run) bewteen points.
If you take the distance from point (-1,3) and (0,4) you get a slope of 1/1, or just 1
y = 1x +4
this could also be:
y = x + 4
(because the 1 is invisible but still there)

How many solutions does the system y = 6x + 6 and y = 6(x + 1) have?
Explain your answer.
Answer:
(-∞,∞)
infinite
Step-by-step explanation:
y= 6x+6; y=6(x+1)
Eliminate the equal sides of each equation and combine
6x+6 = 6(x+1)
solve 6x+6 = 6(x+1) for x
simplify 6(x+1)
apply the distributive property
6x+6 = 6x+ 6*1
multiply 6 by 1
6x+6 = 6x+6
move all terms containing x to the left side of the equation
6=6
and since 6=6, the equation will always be true
The lines y = 6x + 6 and y = 6(x + 1) which consist a system of equation has infinite no. of solutions.
What is the graphical solution of system of equations?Graphical solutions of a system of equations are way of finding the intersection points of all the equations given.
A system with two or more than two equations has a solution only when they have a common intersection point.
Given a system of equation y = 6x + 6 and y = 6(x + 1) ⇒ y = 6x + 6.
As these lines are coinciding to each other so every point of one line lies onto the other therfore they have an infinite no. of solutions.
