Hello!
This is a rectangular prism
The equation to find the volume of a rectangular prism is
V = whl
v is volume
w is width
h is height
l is length
Put in the values you know
V = 12 * 4 * 2
Multiply
V = 96
The answer is 96 cubic feet
Hope this helps!
The expression is:
cos (π / 5) cos (π/7) + sin (π/5) sin(π/7)
This expression can be reduced into a trigonometric function with one angle if we make use of the trigonometric identities. The appropriate identity is:
cos (A - B) = cos A cos B + sin A sin B
If we let
A = π / 5
B = π / 7
Therefore,
cos (π / 5) cos (π/7) + sin (π/5) sin(π/7) = cos (π/5 - π/7) = cos (2π/35)
Answer:
The answer is 15x+5
Step-by-step explanation:
1. Combine like terms (numbers with the same variable) (just add 7 & 8 and add an x)
2. Bring the rest down
3. After you combined like terms make sure you bring the variable down to it's proper spot
5. Hope this helps.. :)
Answer:
A
Step-by-step explanation:
x | y
0 0
1 4
2 n -> 8
3 12
I've rewritten the x-y table so it's easier to read.
Take a point: 2,8. 2 times 4 is 8.
Take another point: 3,12. 3 times 4 is 12.
Ooh, looks like we have a pattern! After testing all the points (which you should always do in case there's an outlier) each x is multiplied by 4 to get the y. The formula for this is <u>y=kx,</u> where k is the constant of proportionality. So the equation is <u>y=4x.</u> This means x and y are directly proportional.
(They would be inversely proportional if in the form y=k/x; jointly proportional if they were in the form z=kxy, and nonproportional if there was no relationship at all.)
Answer: x=-3 and y= -15
Step-by-step explanation: 1 Substitute y=5xy=5x into 4x-2y=184x−2y=18.
-6x=18
−6x=18
2 Solve for xx in -6x=18−6x=18.
x=-3
x=−3
3 Substitute x=-3x=−3 into y=5xy=5x.
y=-15
y=−15
4 Therefore,
\begin{aligned}&x=-3\\&y=-15\end{aligned}
x=−3
y=−15
