Roy made a pizza that is 12 inches in diameter. He knows he can eat about 84.8 in, at what angle should Roy cut the pizza in radians? Round your answer to the tenths place.
Answer:
Cutting angle in radian θ = 3π / 2
Step-by-step explanation:
Given:
Diameter of pizza = 12 inch
He can eat = 84.8 inch²
Find:
Cutting angle in radian
Computation:
Radius of pizza = Diameter of pizza / 2
Radius of pizza = 12 / 2
Radius of pizza = 6 inch
Area of sector = [θ/360][πr²]
Area of sector = [θ/360][(π)(6)²]
84.8 = [θ/360][(π)(36)]
θ = 270°
θ = 270[π/180]
θ = 27π / 18
Cutting angle in radian θ = 3π / 2

A bacteria population is growing exponentially with a growth factor of 1/6 each hour. By what growth factor does the population change each half hour? Select all that apply
Using exponential function concepts, it is found that the change of the growth factor of the population each half hour is given by:
b. [tex]\sqrt{\frac{1}{6}}[/tex]
e. [tex]\left(\frac{1}{6}\right)^{0.5}[/tex]
What is an exponential function?An increasing exponential function is modeled by:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which:
A(0) is the initial value.r is the decay rate, as a decimal.In this problem, the growth factor of 1/6 each hour, hence, [tex]r = \frac{1}{6}[/tex], and:
[tex]A(t) = A(0)(1 + \frac{1}{6})^t[/tex]
For each half-hour, t = 0.5, hence the growth factor is of:
[tex]\left(\frac{1}{6}\right)^{0.5} = \sqrt{\frac{1}{6}}[/tex]
Hence, options b and e are correct.

Answer:
6.9
Step-by-step explanation:
imagine a circle with the center being the point with the 32 degree angle, and with the radius 13.
then
x = sin(32)×13 = 6.9 (6.88895...)
help me plsssssssssssssssssss
Answer:
s = 44.5 m
Step-by-step explanation:
The radius of the circle, r = 17 m
Central angle, [tex]\theta=\dfrac{5\pi}{6}\ rad[/tex]
We need to find the length of the arc. Let the length of the arc is s.
[tex]s=r\theta\\\\=17\times \dfrac{5\pi}{6}\\\\s=44.5\ m[/tex]
So, the length of the arc is equal to 44.5 m.

|x+1|=|2x-6|
Answer:
x = 5, and/or x= - 7/3
Step-by-step explanation:
|x+1|=|2x+6|
We know eitherx+1=2x+6orx+1=−(2x+6)
x+1=2x+6(Possibility 1)
x+1−2x=2x+6−2x(Subtract 2x from both sides)
−x+1=6
−x+1−1=6−1 (Subtract 1 from both sides)
−x=5
(Divide both sides by -1)
x=−5
x+1=−(2x+6)(Possibility 2)
x+1=−2x−6(Simplify both sides of the equation)
x+1+2x=−2x−6+2x(Add 2x to both sides)
3x+1=−6
3x+1−1=−6−1(Subtract 1 from both sides)
3x=−7
Divide both sides by 3
x= −7 / 3
Check answers. (Plug them in to make sure they work.)
x=−5(Works in original equation)
x= −7/3
(Works in original equation)
Answer:
x=−5 or x= −7 / 3

g(-2) + g(2) = 22
Step-by-step explanation:
For x = -2, g(x) = x^2 - 3x
or
g(-2) = (-2)^2 - 3(-2) = 4 + 6 = 10
For x = 2, g(x) = 12, therefore
g(-2) + g(2) = 10 + 12 = 22

Answer:
(E) 72 w^2 is the answer
Step-by-step explanation:
outer square area is 81 w^2
inner square area is 9 w^2
subtracting outer - inner we can get the shaded area
so 81 -9= 72w^2
Answer:
E. 72w²
Step-by-step explain:
Area I = a × a= 9w × 9w
= 81w²
Area II = a × a= 3w × 3w
= 9w²
Shaded area = Area I - area II= 81w² - 9w²
= 72w²

Answer:
3
Step-by-step explanation:
Explanation:
Start at a point like (0,2) which is on the blue f(x) line.
Move upward until you reach the red g(x) line. You should move up 3 units. Every point on f(x) follows the same pattern to land on a corresponding point on g(x). Therefore, this moves the entire blue line up 3 units.
This leads to k = 3
So g(x) = f(x) + 3
