Answer:
The new volume will be 160 mm^3
Step-by-step explanation:
The volume of a triangular prism can be calculated by multiplying the area of the triangular base by the height.
Let’s say we have the base with dimensions a and b, while the height can be h
The volume can be calculated as
V = 1/2 * a * b * h
Now , to answer this question, we shall be choosing arbitrary lengths for a, b and h. Whatever length we shall be choosing , we should make sure that they must be equal to 20 mm^3.
Let’s say we have a as 2mm , b as 4 mm and H as 5 mm
Plugging these into the equation, we surely have our volume as 20 mm^3
Now let’s double these dimensions. Our new dimensions become , 4mm by 8mm by 10mm
Plugging these new values into the equation, we have;
1/2 * 4 * 8 * 10 = 160 mm^3
Thus, our volume is expected to be increased by a factor of 8
Short answer: (-8)^2 + 8 x -8 =
0
Use PEMDAS
"Evaluate the expression" just means solve until you can't simplify anymore. You must solve it in a certain order according to
PEMDAS: Parentheses, Exponents, Multiply, Divide, Add, Subtract.
What does the beginning of the expression look like? It is
.
According to PEMDAS, you must solve what is in the parentheses *first*. But, since there is only a number (-8), there is nothing to solve for and you can move on to exponents.
The squared symbol, the little 2, means you have to square what is *inside* the parentheses.
= 64, because -8 times itself is 64.
Next comes multiplication. Remember, we are not working from left to right. We must multiply the values on the far right before we do any adding, because multiplication comes *before* addition.
(64) + (8 times -8)
(64) + (-64)
Finally, we can add. In this case, because we are adding a negative number, we are really subtracting. 64 + -64 equals 0.
Answer:
y=sin(°/3) means that y equals the sine of a given degree divided by 3.
Answer:
2n(14n^2+3)=28n^4+16n I'm not sure if you meant to put the question mark between or not but I did it separately for -80^2=0 n would equal zero hope this helped
