Let's split this up into two shapes: a half-circle and a triangle.
First, we'll find the area of the half-circle. The formula for the area of a circle is: A = 3.14 * r^2. Therefore, the area of a half circle will be: A = 1/2 * 3.14 * r^2. Using our new formula, let's plug in what we know and solve.
A = 1/2 * 3.14 * 8^2
A = 1/2 * 3.14 * 64
A = 3.14 * 32
A = 100.48 m^2
Next, let's find the area of the triangle. The formula for the area of a triangle is: A = 1/2 * base * height. Using our formula, let's plug in what we know and solve.
A = 1/2 * 12 * 8
A = 6 * 8
A = 48 m^2
Finally, we need to add the area of the half-circle and the area of the triangle to find the area of the shape.
100.48 + 48
148.48 m^2
Hope this helps!! :)
Step-by-step explanation:
area of the triangle
you know the height is 8 bc the radius of the circle is 8[tex] \frac{1}{2} (12)(8) \\ \frac{1}{2} (96) \\ 48[/tex]
area of the half circle
[tex] \frac{1}{2} \pi {(8)}^{2} \\ \frac{1}{2} (3.14)(64) \\ \frac{1}{2} 200.96 \\ 100.48[/tex]
area of entire shape
[tex]48 + 100.48 \\ 148.48 {m}^{2} [/tex]

A section of a deck is shaped like a trapezoid. For this section, the length of one base is 37 feet, and the length of the other base is 46 feet. The height is 20 feet. What is the area of this section of the deck?
Answers
Answer:
[tex]A=830\ ft^2[/tex]
Step-by-step explanation:
Given that,
The length of one base is 37 feet, and the length of the other base is 46 feet. The height is 20 feet.
We need to find the area of this section of the deck that is shaped like a trapezoid.
The area of a trapezium is given by :
[tex]A=\dfrac{a+b}{2}\times h[/tex]
a = 37 ft, b = 46 ft and h = 20 ft
Put all the values,
[tex]A=\dfrac{37+46}{2}\times 20\\\\A=830\ ft^2[/tex]
So, the area of this section of the deck is equal to [tex]830\ ft^2[/tex].

D. 2%
Step-by-step explanation:
The growth rate can be found by looking at the growth factor of the exponential function.
f(x) = (initial value) × (growth factor)^x
The growth rate is related by ...
growth factor = growth rate + 1
This means the growth rate of f(x) is 1.04 -1 = 0.04 = 4%.
__
We can write the function g(x) describing the table as ...
g(x) = (value at x=x1) × ((value at x=x2)/(value at x=x1))^((x-x1)/(x2-x1))
So, this could be ...
g(x) = 31.21 × (32.47/31.21)^((x-2)/2) = a·b^x
where b = (32.47/31.21)^(1/2) ≈ 1.02 . . . . growth factor
This means the growth rate for g(x) is 1.02 -1 = 0.02 = 2%.
__
Then the difference between the growth rates of the two functions is ...
4% - 2% = 2% . . . . . matches choice D

===========================================================
Explanation:
The diagram shows that PT = 4 and QR = 5. Since QR is a radius of the circle, this means that the other radii segments TR and RS are also 5 units long.
Note how PR = PT+TR = 4+5 = 9, and how this segment is the hypotenuse for the right triangles PQR and PRS.
Picking either triangle, we have one known leg of 5 units (the radius mentioned earlier) and the other is unknown. The unknown leg is tangent to the circle, and recall that a tangent segment is always perpendicular to the radius at the point of tangency. So that's why we have right triangles.
Apply the pythagorean theorem to find the length of PQ and PS (both are the same length)
a^2 + b^2 = c^2
a^2 + 5^2 = 9^2
a^2 + 25 = 81
a^2 = 81 - 25
a^2 = 56
a = sqrt(56)
a = sqrt(4*14)
a = sqrt(4)*sqrt(14)
a = 2*sqrt(14)
The exact length of PQ and PS is 2*sqrt(14) units.
---------
We have enough to find the perimeter of quadrilateral PQRS. We add up the exterior sides. That means we ignore the interior segment PR.
perimeter = PQ+QR+RS+SP
perimeter = 2*sqrt(14)+5+5+2*sqrt(14)
perimeter = 10+4*sqrt(14)
Answer is choice B

V ≈ 3367.6 cm³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = [tex]\frac{4}{3}[/tex] πr³ ( r is the radius )
Here D = 18.6 , then r = 18.6 ÷ 2 = 9.3 , so
V = [tex]\frac{4}{3}[/tex] × 3.14 × 9.3³
= [tex]\frac{4}{3}[/tex] × 3.14 × 804.357
= [tex]\frac{4(3.14)(804.357)}{3}[/tex]
≈ 3367.6 cm³ ( to the nearest tenth )

Step-by-step explanation:
The quadratic regression equation for the data set is:
y^ = -0.175x²-3.786x+121.119
What is Quadratic Regression Equation?Quadratic regression is the process of determining the equation of a parabola that best fits a set of data. This set of data is a given set of graph points that make up the shape of a parabola. The equation of the parabola is y = ax² + bx + c, where a can never equal zero.
According to the given problem,
Let us choose any value of x,
x = 10
For this value of x we can see that the respective value of y= 50
Substituting the value of x in the equations to see which equation satisfies the value of y as 50.
Substituting the value of x in the equation:
y^ = -0.175x²-3.786x+121.119
y^ = 50
Hence, we can conclude that y^ = 0.175x² - 3.786 + 121.119 is the quadratic regression equation for the given data set.
