The circumference of the circle is 18π meters.
What is circumference?The distance along a circle's perimeter is referred to as its circumference.
The circumference of a circle can be found by the formula: C = πd, where d is the diameter of the circle.
Given that the diameter of the circle is 18m, we can find its circumference by:
C = πd
C = π18
C = 18π
Therefore, the circumference of the circle is 18π meters.

must earn at least $90. If z represents the number of hours lifeguarding and y
represents the number of hours walking dogs, write and solve a system of inequalities
graphically and determine one possible solution.
Answer:

What is the slope of the line in the graph?
Answer:
m = 1/4 (the slope is 1/4)
I selected the points (0,1) and (4,2), but if you choose (-4,4) and (0,1), then your slope would be -3/4----------------------------------------------------------------------------------------------------

The permutation of 6 things taken 4 at a time is 360 So, option C is correct.
What are permutations?The different arrangements which can be made out of a given number of objects by taking out some or all at a time are called permutations.
The permutation of 6 things taken 4 at a time.
It is calculated as follows;
[tex]^6P_ 4[/tex] = 6!/(6-4)! =6!/2!
[tex]^6P_ 4[/tex] = (6×5×4×3×2×1) ÷ (2×1)

Slope is 5, and (5,3) is on the line
The equation of the line is y=___
Answer:
y = 5x - 22
Step-by-step explanation:
In this question, we have to find the equation of the line.
We know that the slope is 5 and passes through (5, 3) on the graph.
We know that our equation must be in slope-intercept form: y = mx + b
To find our y-intercept, or "b", we would plug in our given information and solve for b.
Solve for b:
3 = 5(5) + b
3 = 25 + b
Subtract 25 from both sides.
-22 = b
This means that our y-intercept is -22. We can now make our equation with our new information:
y = 5x - 22
The equation of the line is y = 5x - 22

X is defined for all numbers on the domain starting at x=0. It doesn’t show or mention a cutoff/equation in the picture so it’s safe to assume it continues forever
To find the domain from the graph, you have to focus only x-axis because domain is the set of x-value.
From the graph, we can see that domain starts at x = 0 and keeps going and going positive infinitely. That means the domain must be greater or equal to 0.
Here is an easier way to understand
[tex]\large \boxed{ \sf{left/start}} \Longrightarrow \large \boxed{ \sf{right/end}}[/tex]
[tex] \large \sf{left = 0} \\ \large \sf{right = + \infin}[/tex]
And if we combine both, we get
[tex]0 \leqslant x \leqslant + \infin[/tex]
But we don't usually write positive infinity, therefore we convert to
[tex]0 \leqslant x \longrightarrow x \geqslant 0 \\ x \geqslant 0[/tex]
Answer[tex]x \geqslant 0[/tex]

Find the tan of E
PLEASE HURRY
Step-by-step explanation:
from the picture we got angle HFG is 45 degree.
let x is the length of HF
we got sin45=sqrt(8)/x
1/sqrt(2)=sqrt8/x
x=sqrt16
x=4
note that x is the length of HF
let y is the length of HE
use pythagorean theory
3^2+4^2=y^2
9+16=y^2
25=y^2
5=y
so tanE is x/y
tanE=4/5

The area of a square park is the same as of a rectangular park.If the side of the square park is 60m legth of the rectangular park is 90m.Find the breadth of the rectangular
Answer:
The width of the rectangular park is 40m.
Step-by-step explanation:
We are given that the area of a square has the same area as the rectangle (the fact that they're parks doesn't matter)
We are also given one length side of the square, and since squares have all equal sides, we know all the side lengths are 60m.
To find Area, we do L * W, so it would be 60 * 60 = 3600.
That means the area of the rectangle park is 3600m. One side of the rectangle is 90m, so the formula is L * W = A. So we plug in known values of the rectangle which would be 90 * W = 3600. To find W, we do 3600/90 which is 40.
Let me know if you have any questions
