Answer:
hmmmm........
Step-by-step explanation:
radius is 4/2=2m
volume of the cylinder is equal
to πr^h
i.e, π(2m)^2×7m
≈88 m^3
3:8 = n:32
you multiply the ratio 3:8 by 4 to get the 32 female performers, so you multiply the 3 by 4 to get the variable n, which is how many men there are. so, 3×4=12
3:8 × 4:4 = 12:32
there are 12 men in the recital.
hope that helped and wasn't too confusing!
Answer:
The point after the reflection: ![(-4,-8)](https://tex.z-dn.net/?f=%28-4%2C-8%29)
Step-by-step explanation:
-Statement: If you reflect the point
across <u>x-axis</u> or the <u>y-axis</u>, then the
and the
of the point can change either positive, negative or the same, depending on where the point is located on a graph.
-So, if you reflect the point
across <u>x-axis</u>, then the point after the reflection, would be
:
The following point: ![(-4, 8)](https://tex.z-dn.net/?f=%28-4%2C%208%29)
The point after the reflection: ![(-4,-8)](https://tex.z-dn.net/?f=%28-4%2C-8%29)
Answer:
x = 1 y = 1
Step-by-step explanation:
Pythagoras' Theorem: ![a^{2} + b^{2} = c^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2B%20b%5E%7B2%7D%20%3D%20c%5E%7B2%7D)
a = 1
b = 1 Let's substitute a and b into the equation to work out what c, the hypotenuse, is. C needs to equal
so if this doesn't give us the answer, then we have to use another of the values given.
Here, we substitute in the values.
Here, we simplify the ![1^{2}](https://tex.z-dn.net/?f=1%5E%7B2%7D)
Next, we have to square root to give us the hypotenuse.
c =
Therefore, x = 1 and y = 1
I hope that helps you, buddy!!
Hello!
First of all we need to find the slope. To do so we use the following equation.
![\frac{ y_{2}- y_{1} }{ x_{2}- x_{1} }](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20y_%7B2%7D-%20y_%7B1%7D%20%20%7D%7B%20x_%7B2%7D-%20x_%7B1%7D%20%7D%20)
The ones and twos just represent different ordered pairs. We will have (-3,3) be (
![x_{1} , y_{1}](https://tex.z-dn.net/?f=%20x_%7B1%7D%20%2C%20y_%7B1%7D%20)
) and (3,1) be (
![x_{2} , y_{2}](https://tex.z-dn.net/?f=%20x_%7B2%7D%20%2C%20y_%7B2%7D%20)
) Now we plug our numbers into the formula.
![\frac{1+3}{3+3} = \frac{4}{6} = \frac{2}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%2B3%7D%7B3%2B3%7D%20%3D%20%20%5Cfrac%7B4%7D%7B6%7D%20%3D%20%20%5Cfrac%7B2%7D%7B3%7D%20)
---------------------------------------------------
Now we need to write our equation in point-slope form, which is y-k=m(x-h), where (h,k) represent a point on the line, and m is the slope.. We will use (3,1) for (h,k). Our final equation is shown below.
y-1=
(x+3)
I hope this helps!
