Answer:
Radius.
Step-by-step explanation:
● The distance from the centre to any other point on the circle is known as the radius.
Other Definitions:
● Diameter is the the distance from one point to another point of the circle which passes through the centre of the circle.
● The space enclosed by a figure is known as its area. Area of a circle = πr²
● Circumference of a circle is its outer perimeter. Circumference = 2πr

A garden table and a bench cost $984 combined. The garden table costs $84 more than the bench. What is the cost of the bench?
Answer:
$450
Step-by-step explanation:
a garden table costs $84 more than the bench,
therfore, $900-84 = $900
$900/2 = cost of bench
$450 = cost of bench

Find the mean of the data in the dot plot below. Make sure to show your work and explain the steps you took in solving the problem. please help I took a picture I just need the problem to be explained
Answer: 6.
Step-by-step explanation: To find the mean, the first step is to add all the data together. Here's how it should look:
2 + 3 + 6 + 6 + 7 + 8 + 8 + 8 = 48.
Next, you need to divide whatever you get after adding the data by how many numbers there are for your data. In this case, 48 was the answer when we added all the data. In total, you have 8 numbers in your data, so you need to divide 8 from 48. It should look like this:
48 / 8 = 6.
Therefore, the mean for this data set is 6.
Have a great day! :)
Find the arc length of the partial circle.
Either enter an exact answer in terms of π or use 3.14 for π and enter your answer as a decimal.
Explanation:
A full circle of radius r has a circumference of 2pi*r which is the perimeter aka distance around the circle's edge.
We divide that by 4 to get the arc length of the quarter circle and we'd get to (2pi*r)/4 = 0.5pi*r
Plug in r = 1 and pi = 3.14
0.5*pi*r = 0.5*3.14*1 = 1.57
Given a trapezoid with a height of 4.3m and bases of 9.2 m and 3.2m, what is the area of the trapezoid? Do not include units in your answer.
For a height of 4.3m and bases of 9.2 m and 3.2m, the area of the trapezoid is mathematically given as
A=26.7
What is the area of the trapezoid?Generally, the equation for the trapezoid is mathematically given as
A=0.5*(a+b)*h
Therefore
A=0.5*(3.2+9.2)*4.3
A=26.7
In conclusion,area of the trapezoid
A=26.7

Evaluate this:
[tex]\displaystyle\rm\int_0^\frac{\pi}{2}\sqrt{\sin x}\ dx \times \int_0^\frac{\pi}{2}\frac{1}{\sqrt{\sin x}}\ dx[/tex]
Only elementary methods are allowed.
The first integral has a well-known beta function representation, so the second one should too. The beta function itself is defined as
[tex]B(x,y) = \displaystyle \int_0^1 t^{x-1} (1-t)^{y-1} \, dt[/tex]
and satisfies the identity
[tex]\displaystyle B(x,y) = \frac{\Gamma(x) \Gamma(y)}{\Gamma(x+y)}[/tex]
Later on, we'll also use the so-called reflection formula for the gamma function; for non-integer z,
[tex]\Gamma(z) \Gamma(1-z) = \dfrac{\pi}{\sin(\pi z)}[/tex]
as well as the identity
[tex]\dfrac{\Gamma(z+1)}{\Gamma(z)} = z[/tex]
Replace [tex]x\to\sin^{-1}(x)[/tex] in both integrals, so that
[tex]\displaystyle \int_0^{\frac\pi2} \sqrt{\sin(x)} \, dx = \int_0^1 \frac{\sqrt x}{\sqrt{1-x^2}} \, dx[/tex]
[tex]\displaystyle \int_0^{\frac\pi2} \frac{dx}{\sqrt{\sin(x)}} = \int_0^1 \frac{dx}{\sqrt x \sqrt{1-x^2}}[/tex]
Now replace [tex]x\to\sqrt x[/tex] :
[tex]\displaystyle \int_0^1 \frac{\sqrt x}{\sqrt{1-x^2}} \, dx = \frac12 \int_0^1 x^{-\frac14} (1-x)^{-\frac12} \, dx = \frac12 B\left(\frac34, \frac12\right) [/tex]
[tex]\displaystyle \int_0^1 \frac{dx}{\sqrt x \sqrt{1-x^2}} = \frac12 \int_0^1 x^{-\frac34} (1-x)^{-\frac12} \, dx = \frac12 B\left(\frac14, \frac12\right)[/tex]
So, the original integral (which I condense here to a double integral) is
[tex]\displaystyle \int_0^{\frac\pi2} \int_0^{\frac\pi2} \sqrt{\frac{\sin(x)}{\sin(y)}} \, dx \, dy = \frac14 B\left(\frac34, \frac12\right) B\left(\frac14, \frac12\right)[/tex]
[tex]\displaystyle = \frac14 \frac{\Gamma\left(\frac14\right) \Gamma\left(\frac34\right) \Gamma\left(\frac12\right)^2}{\Gamma\left(\frac54\right) \Gamma\left(\frac34\right)}[/tex]
[tex]\displaystyle = \frac14 \frac{\Gamma\left(\frac14\right) \Gamma\left(\frac34\right) \Gamma\left(\frac12\right)^2}{\frac14 \Gamma\left(\frac14\right) \Gamma\left(\frac34\right)}[/tex]
[tex]\displaystyle = \Gamma\left(\frac12\right)^2 = \frac{\pi}{\sin\left(\frac\pi2\right)} = \boxed{\pi}[/tex]

A college student takes the same number of credits each semester. She had 8 credits when she started, and after 7 semesters, she had 92 credits.
Which of these expresses the rate at which she is earning credits
Answer:
12 credits per semester
Step-by-step explanation:
she has 92 in the end but she started off with 8 so your first step is to subtract 8 from 92 which gives you 84 once you get 84 you divide that by 12 you get 7 which means she got 12 credits in each of her 7 semeters

Answer:
[tex]\sf 5x+6y=12[/tex]
Step-by-step explanation:
[tex]\sf y=-\dfrac{5x}{6}+2[/tex]
Multiply both sides by 6:
[tex]\implies \sf 6 \cdot y=6(-\dfrac{5x}{6}+2)[/tex]
Expand:
[tex]\implies \sf 6y=-5x+12[/tex]
Add 5x to both sides:

A car travels at an average speed of 56 miles per hour. How many miles does it travel in 4 hours and 45 minutes?

?
I
Answer:
266 miles
Step-by-step explanation:
Given statement
4 hours and 45 minutesClearly, 45 is 3/4th of an hour. Thus, this statement can also be written as:
⇒ 4 hours and 3(Hour)/4 minutes⇒ 4 hours + 3(Hour)/4 minutes⇒ 4 hours + 0.75(Hour)⇒ 4.75 hoursWe are given that:
56 miles per hourWhen we convert this statement into an equation, we get:
⇒ 56 miles = 1 hourMultiply both sides by 4.75 to obtain the distance in 4.75 hours.
⇒ 56 × 4.75 miles = 1 hour × 4.75⇒ 266 miles = 4.75 hourswhat is the inverse of f(x)=2(3^x)
If [tex]f^{-1}(x)[/tex] is the inverse of [tex]f(x)[/tex], then by definition
[tex]f\left(f^{-1}(x)\right) = x[/tex]
so that
[tex]2 \times 3^{f^{-1}(x)} = x[/tex]
Solve for [tex]f^{-1}(x)[/tex] :
[tex]3^{f^{-1}(x)} = \dfrac x2[/tex]
[tex]\log_3\left(3^{f^{-1}(x)}\right) = \log_3\left(\dfrac x2\right)[/tex]
[tex]f^{-1}(x) \log_3(3) = \log_3\left(\dfrac x2\right)[/tex]
[tex]\boxed{f^{-1}(x) = \log_3\left(\dfrac x2\right)}[/tex]

The required inequality that represent the given scenario is :
[tex]\qquad \tt \dashrightarrow \:x \geqslant 4[/tex]
where, x is height in feet.
Let's interpret the information given:
4 feet or taller ⇒ the person can be 4 feet or above 4 feetLet's set 'x' as the hypothetical height of a person
Therefore the inequality should be x ≥ 4
⇒ we put x as greater than 4 since the person must be taller than 4
feet to ride the roller coaster
⇒ we also put the '_' under the inequality to signify that the person
can equal 4 feet in height and still be eligible to ride the roller
coaster

What are the greatest common factors of 21 and 32?
Answer:
1
Step-by-step explanation:
The biggest common factor number is the GCF number. So the greatest common factor 21 and 32 is 1. Also check out the Least Common Multiple of 21 and 32
The greatest common factor of 21 and 32 is 1.
What is Greatest Common Factor?Greatest common factor or GCF of two numbers is defined as the one common factor of the two given numbers which is the greatest of all the common factors.
GCF is also usually known as Highest Common Factor (HCF).
We have to find the greatest common factors of 21 and 32.
One of the method to find GCF is by prime factorization.
First prime factorize the two numbers. The product of the commonly shared prime factors will be the GCF.
If they don't share any common prime factors, then the GCF will be 1.
21 = 3 × 7
32 = 2 × 2 × 2 × 2 × 2
There are no common prime factors, GCF will be 1.
Hence, the greatest common factor of 21 and 32 is 1 since there are no common prime factors.
