Answer:
Below.
Step-by-step explanation:
You find the values of y by substituting the values of x in the expression x^2 + 3x - 1.
So f(-4) = (-4)^2 + 3(-4) - 1 = 16-12-1 = 3
in the same way f(-3) = -1, f(-2) = -3, f(-1) = -3,
f(0) = -1 and f(1) = 3.
Now plot the points (-4, 3) , (-3, -1) and so on
Then you can read the values off this graph.
Answer:
Equation: 5.5x = 168.5
Solution: 30 shirts
Step-by-step explanation:
First, create the equation where x is the number of shirts.
Since each shirt is $5.50, the cost of the shirts will be 5.50x
Set this equal to 168.50, since that is how much money Kareendeep has.
So, the equation will be 5.5x = 168.5
Now, solve this for x, the number of shirts she can buy:
5.5x = 168.5
Divide each side by 5.5
x = 30.6
Since we can only have a whole number of shirts, she can only buy 30 shirts.
So, the answer is 30 shirts.
Answer:
No
Step-by-step explanation:
NO...... any two sides added together must be GREATER THAN the third side .... 2 + 8 is NOT greater than 19
2n-9-5-8n+4n
= 2n-14-4n
=2n-14
Yay, I like das stuff
I think I learned the washer method
goes like this
![area=\pi \int\limits^a_b {(outercurve)^2-(innercurve)^2} \, dx](https://tex.z-dn.net/?f=area%3D%5Cpi%20%20%5Cint%5Climits%5Ea_b%20%7B%28outercurve%29%5E2-%28innercurve%29%5E2%7D%20%5C%2C%20dx%20%20)
ok, so
actuallly, this is easier
y=49-x^2 and
y=0
see when they intersect again
they intersect at -7 and 7
if we do integrate from -7 to 7, then it wil give 0 (because integration is area under the curve), so note that they are same both sides so integrate from 0 to 7 then double the volume to get both sides
so it can't be C or D
It also can'nt be A because it should not be multipied by 4, it should be multipied by 2
basically, we don't need the washer method
remember, area=pir^2
the disk method then
we are summing up all the radii disks and squareing them
but doubleing them so
![area=2\pi (\int\limits^7_0 {49-x^2} \, dx )^2](https://tex.z-dn.net/?f=area%3D2%5Cpi%20%20%28%5Cint%5Climits%5E7_0%20%7B49-x%5E2%7D%20%5C%2C%20dx%20%29%5E2%20)
no idea why we need the inside part to be x(49-x^2), that is intersting
