90. you can just do 5x12 which is 60. 60x3 is 180 then 180 divided by 2 because a triangular prism is just half of a cube
Answer:
x = ± sqrt(43)
Step-by-step explanation:
2x^2 - 28 = x^2 + 15
Subtract x^2 from each side
2x^2-x^2 - 28 = x^2-x^2 + 15
x^2 -28 = 15
Add 28 to each side
x^2 - 28 +28= 15+28
x^2 = 43
Take the square root of each side
sqrt(x^2) = ± sqrt(43)
x = ± sqrt(43)
Answer:
option A.
Step-by-step explanation:
We know that the volume of a rectangular prism is the product of its base area and height. That is to say:
Volume = Base Area x Height
Where: x^3-3x^2 +5x-3
Height: x^2-2
Volume =
Solving for "Height" we have:
Height = Volume / Base Area
Height = (x^3-3x^2 +5x-3) / (x^2-2)
Using ruffinis law we have that the solution is:
x-3 with a remainder of 7x-9
That is to say:
x-3 + (7x-9)/(x^2 - 2)
That is option A.
Answer:
Step-by-step explanation:
It is a parameter, I think. The population is limited to all of the restaurant's customers. Presumably they don't come in to look at the waitresses -- although that might happen. They are there for coffee donuts or a meal, so they are spending money, that's what all of them have in common.
So the population is very confined and very well defined.
The owner is finding a mean. Anything like this is a parameter which defines some aspect of the population.
A)
sin(40°) = AC/10°
(10°)sin(40°) = AC
