Answer:
43 meters
Step-by-step explanation:
Perimeter is 2l+2w
l equals length
w equals width
264 = 2*89 + 2w
264 = 178 + 2w
264 - 178 = 2w
2w = 86
w = 43
Sergey is solving 5x2 + 20x – 7 = 0. Which steps could he use to solve the quadratic equation by completing the square? Select three options. 5(x2 + 4x + 4) = –7 + 20 x + 2 = Plus or minus StartRoot StartFraction 27 Over 5 EndFraction EndRoot 5(x2 + 4x) = 7 5(x2 + 4x + 4) = 7 + 20 5(x2 + 4x) = –7
The steps Sergey could use to solve the quadratic equation by completing the square is 5(x2 + 4x) = –7
How to use the completing the square method?We should know that in completing the square method both sides of the equation are made perfect squares.
The given equation is 5x²+20x-7=0
Solving this equation by completing the square method we have
5(x²+4x+4)=-7
This means that (x+2)=±√27/5
Simplifying further we have
5(x²+4x)=7
Then expanding to make ²HS a perfect square we have
5(x²+4x+4)=7+20
This means that 5(x²+4x)=-7
Therefore the step he could use is 5(x²+4x)=-7\

Find the center and radius of the circle with a diameter that has endpoints (-6,10)
and (2,3)Enter the center as an ordered pair, : Enter the radius as a decimal correct to three decimal places :
Step-by-step explanation:
the center of the circle is the midpoint of the diameter.
and the radius is the distance of the midpoint to either endpoint (or simply half of the distance between the diameter endpoints).
the midpoint between points A and B
(xm, ym) = ((xa + xb)/2, (ya + yb)/2)
in our case the midpoint (center of the circle) is
((-6 + 2)/2, (10 + 3)/2) = (-4/2, 13/2) = (-2, 6.5)
about the radius
diameter² = (-6 - 2)² + (10 - 3)² = (-8)² + 7² = 64 + 49 =
= 113
diameter = sqrt(113) = 10.63014581...
radius = diameter / 2 = 5.315072906... ≈ 5.315

The area of a triangle with the given base and height is 4 1/6 square inches.
Given that, the base of a triangle is 1 2/3 inches and the height of a triangle is 5 inches.
What is the area of the triangle?The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.
Now, the mixed fraction 1 2/3 can be written as 5/3
The area of the triangle=1/2 × 5/3 × 5
To multiply the fractions multiply the numerators of the fraction and write the product in the numerator and multiply the denominators of the fractions and write the product in the denominators.
That is, (1/2 × 5/3) × 5/1
=5/6 × 5/1
=25/6
=4 1/6
So, the area of a triangle with a base of 5/3 inches and height 5 inches is 4 1/6 square inches.
Therefore, the area of a triangle with the given base and height is 4 1/6 square inches.

Answer:
A = 22.62°

c = 26
Step-by-step explanation:
\(a^2+b^2=c^2\\10^2+24^2=c^2\\100+576=c^2\\676=c^2\\26=c\)
\(\sin A=\frac{\text{Opposite}}{\text{Hypotenuse}}=\frac{10}{26}\\\\A=\sin^{-1}(\frac{10}{26})\\\\A\approx22.62^\circ\)<-- You can also use other trig ratios

A Ferris Wheel is set up at the carnival it has a diameter of 45 feet. What is the total circumference if the ferris wheel makes 4 rotations around?
Answer:
The circumference is 565.2 feet when the ferris wheel makes 4 rotations.
Step-by-step explanation:
Given that the diameter of the wheel is 45 feet.
That is:
\(d = 45\ feet\)
We have to find the radius first
\(r = \frac{d}{2} = \frac{45}{2} = 22.5\ feet\)
The circumference of the circular wheel for one rotation will be:
\(C = 2\pi r\)
And for four rotations' circumference the circumference of one rotation will be multiplied with 4.
\(C = 2 * 3.14 * 22.5\\C = 141.3\ feet\)
Total circumference:
\(C_T = 4C\\= 4 * 141.3\\=565.2\ feet\)
Hence,
The circumference is 565.2 feet when the ferris wheel makes 4 rotations.

The quadratic function is defined as follows:

How to define the quadratic function?A quadratic function with vertex at coordinates (h,k) is given as follows:

Hence:
y = a(x - 40)² + 160.
The ball landed 80 feet from where it was kicked, hence when x = 80, y = 0, and the leading coefficient a is calculated as follows:
0 = a(80 - 40)² + 160

The volume of a rectangular prism is 5,890.625 cm3. If the height is 14.5 cm and the length is 25 cm, what is the value of the width?
Answer:
Step-by-step explanation:
The formula for the volume of a rectangular prism is V = lwh, where V is the volume, l is the length, w is the width, and h is the height.
We know that V = 5,890.625 cm^3, h = 14.5 cm, and l = 25 cm.
Substituting these values into the formula, we get:
5,890.625 = 25w(14.5)
5,890.625 = 362.5w
w = 16.25
Therefore, the width of the rectangular prism is 16.25 cm.
Answer:
It's A

Barry Beach was convicted of murder in 1983 and sentenced to life in prison without parole. In 2015, Governor Bullock commuted Beach's sentence after years of controversy surrounding Beach's confession, trial and subsequent conviction. A news program in Bozeman wanted to find out more about how people in Montana feel about Beach's release. The local program invited viewers to go their website and indicate their opinions. At the end of the show, 72% of people who voted in the poll indicated they agreed with Bullock's decision.

The required, simplified expression is 2x - 6y(2a - x) + 6y.
To simplify the expression (2x+6yx)-(12ay+-6y), we need to distribute the negative sign to the second term.
2x - 6y(2a - x) + 6y.
Now we can combine like terms, which means adding up any terms that have the same variables raised to the same powers. In this case, we have two terms with "x" and two terms with "y". Combining them, we get:
2x+6yx-12ay+6y = 2x - 12ay + 6yx + 6y

b. Which function has the greatest growth factor? Justify your response.
Answer:
A)
Function A: Exponential
Function B: Linear
Function C: Exponential
Function D: Exponential
B) Function A
Step-by-step explanation:
Function A: This is exponential because- (1, 3)(2,9)(3,27)
It is not going up by the same number each time. However, it is multiplying by 3 each time which means it is exponential.
Function B: This is linear because- (1, 64)(1, 80)(1, 96)
It is going up by 16 each time, (a constant number) which means it is linear.
Function C: This is exponential because- there is a curve, linear is always a straight line. But, this has a curve which means it is exponential.
Function D: This is exponential because- It is increasing by a percentage and not a constant number. It is increasing by 1% which means it is exponential.
The function that has the greatest growth factor is Function A because, Function A multiplies by 3 each time. Function B is linear, exponential functions always pass linear functions despite how "steep" they are. Eventually, the exponential function will surpass it. Function C is also exponential but is not as "steep" as Function A. Function A multiplies by 3 each time but Function C increases less. Function D is also exponential, and for the same reasons as Function C, Function A has the greatest growth factor.
