Answer:
The area of the sector (shaded section) is 29.51 [tex]m^{2}[/tex].
Step-by-step explanation:
Area of a sector = (θ ÷ 360) [tex]\pi[/tex][tex]r^{2}[/tex]
where θ is the central angle of the sector, and r is the radius of the circle.
From the diagram give, diameter of the circle is 26 m. So that;
r = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{26}{2}[/tex] = 13 m
θ = 360 - (180 + 160)
= 360 - 340
= [tex]20^{o}[/tex]
Thus,
area of the given sector = [tex]\frac{20}{360}[/tex] x [tex]\frac{22}{7}[/tex] x [tex](13)^{2}[/tex]
= [tex]\frac{20}{360}[/tex] x x [tex]\frac{22}{7}[/tex] x 169
= 29.5079
The area of the sector (shaded section) is 29.51 [tex]m^{2}[/tex].

Step-by-step explanation:
g(-4) here x = -4
So, we have to take g(x) = x - 2
g(-4) = -4 -2 = - 6
g(1) , here x = 1 ,
So, we have to take g(a)= -x +1
g(-1) = -1 + 1 = 0
g(-4) + g(-1) = -6 +0 = -6

find the vertex form of 4x^2+8x-8
Answers
Answer:
4(x + 1)^2 - 12.
Step-by-step explanation:
f(x) = 4x^2 + 8x - 8
f(x) = 4(x^2 + 2x) - 8
f(x) = 4[(x + 1)^2 - 1) - 8
f(x) = 4(x + 1)^2 - 4 - 8
f(x) = 4(x + 1)^2 - 12.

Write an equation to model the relationship between the number of weeks, x, and the number of views, f(x).
Enter the correct answer in the box by replacing the values of a and b.
Answers
Answer:
a = 5120
b = 1.25
Step-by-step explanation:
Let the exponential function representing the given table is,
f(x) = [tex]a(b)^x[/tex]
Here, f(x) = Number of views
x = Number of weeks
We choose two points from the given table and satisfy the equation of the function.
Let the points are (0, 5120) and (1, 6400)
For a point (0, 5120),
f(0) = a(b)⁰ = 5120
a = 5120
Now for the second point (1, 6400),
6400 = 5120(b)¹
b = [tex]\frac{6400}{5120}[/tex]
b = 1.25
Therefore, a = 5120 and b = 1.25 are the values.

Ryan's take-home pay is $2,500 each month. The amount for gas is $125. Calculate the percentage Ryan uses on gas from his take-home pay. please help!! O^O
Answers
Answer: 5%
Step-by-step explanation:
Since Ryan's take-home pay is $2,500 each month and the amount for gas is $125.
The percentage that Ryan uses on gas from his take-home pay will be:
= Amount used on gas / Take home pay × 100
= 125/2500 × 100
= 1/20 × 100
= 5%
He used 5% on gas.

louise decided to purchase a new mountain bike when he saw the sporting good store was offering 20% off their bike. what is the total cost of the mountain bike if the originally price at $249 and louise must pay 7.5% sales tax
Answers
First off $249 x 20% = $49.8 so, $249- 49.8 = 199.2 ( the price after deducting the discount), 199.2 x 8% = 15.93 (this is the price of the tax), and 199.2 + 15.93 = $215.13 ( this is the price after the discount and with taxes) :D
