The diameter of a circle measures 18ft what is the circumference of the circle? Use 3.14 for π and do not round
=======================================================
Work Shown:
d = diameter = 18 ft
pi = 3.14 approximately
C = circumference
C = pi*d
C = 3.14*18
C = 56.52
The distance around the circle's edge (aka perimeter) is about 56.52 feet
The result is approximate since pi = 3.14 is approximate.

If the simple interest on $7000 for 10 years is $6300, then what is the interest rate? I will pick branliest answer with the most thorough explanation. Please help. If you do, thanks for helping! Use the picture below for question.
Answer:
0.09
Step-by-step explanation:
So if you use the Simple interest equation it will begin with:
Interest total = Initial Amount of money x Interest rate per year x Years money is invested for.
Then substitute the values you have been given so:
$6300 = 7000 x Interest rate per year x 10.
This is simplifies to 6300 = 70,000 x Annual Interest rate
You can rearrange this to find the annual interest rate by dividing by 70,000:
[tex]\frac{6300}{70000} = Interest\ rate[/tex]
Simplifying this would be:
[tex]\frac{63}{700}\\[/tex] = Interest rate.
The interest rate is 0.09.

List a specific example with a set and a subset.
Your example needs to be unique and in your own words.
Some examples:
The set of all animals in the world. A subset could be the group of all dogs. The set of all people in a country. A subset would be the group of people in a small town of that same country.Everything in a person's house (set), vs items located inside the person's kitchen only (subset).The set of parallelograms. A subset is the set of all squares.The set of rational numbers, in which the collection of integers is a subset.With each example, any item or person in the subset is also found in the original set (but not vice versa). For example, any dog is an animal but not the other way around.
If you were to draw a venn diagram, then the larger circle is the set of all animals, while the subset of all dogs is a smaller circle drawn completely inside the larger one.
Those examples listed above is of course not the complete list of set & subset combos. Feel free to get creative and think of others.

alex has 5 t-shirts in the drawer. 2 are white, and the rest are black. He will pick a t-shirt from the drawer without looking, and then without replacing it, will pick a second t-shirt without looking. What is the probability that he will pick a white t-shirt on his first pick and a black t-shirt on his second pick?
Answer:
24%
Step-by-step explanation:
Lets consider it.
2 are white, and 3 are black.
2/5 chance of him getting white, and 3/5 chance of him getting black
So he successfully gets white on his first try.
2/5
Then he successfully gets black on his second try
2/5 * 3/5, or 6/25, or 24% of him getting white, then black.

The Area of Triangle UVW be 16 squared units.
What is Area of Triangle?The area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.
Area of triangle I = [tex]\frac{1}{2} *b*h[/tex]

Find the exact location of all the relative and absolute extrema of the function. (order your answers from smallest to largest x. ) g(x) = x2 − 4 x
The minima of the quadratic function is at the vertex, it is at (2, -4).
Where are the relative minima/maxima of the function?
First, we can see that our function is a quadratic function of positive leading coefficient. So it opens upwards.
Then we will only have a minima, which is located in the vertex of the parabola.
Remember that for:
y = a*x^2 + b*x + c
The x-value of the vertex is h = -b/2a
Then for g(x) = x^2 - 4x we have:
h = -(-4)/2*1 = 2
And the y-value of the vertex is:
g(2) = 2^2 - 4*2 = -4
Meaning that the minima of the function g(x) is (2, -4).

Find the average rate of change for the function f(x) = 2x + 4 over an interval [2, 6].
Answer:
average rate of change = 2
Step-by-step explanation:
since f(x) is a linear function, then the slope is the measure of the average rate of change of f(x).
note the average rate of change is constant over any closed interval.
the equation of a linear function in slope- intercept form is
f(x) = mx + c ( m is the slope and c the y- intercept )
f(x) = 2x + 4 ← is in slope- intercept form
with slope m = 2
then average rate of change = 2

Separate 79 into two parts such that 4 times the smaller exceeds the larger by 6.
1. Assign the variables.
2. Write the equations.
3. Solve the system.
4. Answer the question.
39 is separated into two parts 9 and 30
Step-by-step explanation:
The given is:
Separate 39 into two parts
4 times the smaller part exceeds the larger part by 6
Assume that the smaller part is x and the larger part is y
∵ 39 is separate into two parts x and y
∴ x + y = 39 ⇒ (1)
∵ x is the smaller part
∵ y is the larger part
∵ 4 times the smaller part exceeds the larger part by 6
- Multiply x by 4 and subtract y from it to get 6
∴ 4x - y = 6 ⇒ (2)
Now we have a system of equations to solve it
Add equations (1) and (2) to eliminate y
∵ (x + 4x) + (y - y) = (39 + 6)
∴ 5x = 45
- Divide both sides by 5
∴ x = 9
Substitute the value of x in equation (1) to find y
∴ 9 + y = 39
- Subtract 9 from both sides
∴ y = 30
∴ The smaller part is 9 and the larger part is 30
39 is separated into two parts 9 and 30
