Answer:
T(-4) = -(-4)-2 = 2
Step-by-step explanation:
If you have -4 as the x value, all you have to do is substitute -4 in for x in the equation you are given, so it would be -(-4)-2. Now, you have a negative outside of your parenthesis -4, so that will have to be distributed to the -4, and it becomes positive 4. That will then make the equation 4-2, which then makes 2 your overall answer.
Answer:
90
Step-by-step explanation:
Evaluate x^2 + 2 x^2 + 3 x^2 + 4 x^2 where x = 3:
x^2 + 2 x^2 + 3 x^2 + 4 x^2 = 3^2 + 2×3^2 + 3×3^2 + 4×3^2
3^2 = 9:
3^2 + 2×9 + 3×3^2 + 4×3^2
3^2 = 9:
3^2 + 2×9 + 3×9 + 4×3^2
3^2 = 9:
3^2 + 2×9 + 3×9 + 4×9
3^2 = 9:
9 + 2×9 + 3×9 + 4×9
2×9 = 18:
9 + 18 + 3×9 + 4×9
3×9 = 27:
9 + 18 + 27 + 4×9
4×9 = 36:
9 + 18 + 27 + 36

Answer: 90
Answer:
168.75π cm^3 is your answer.
Volume of a cone is 1/3 πr^2h.
Here, radius is given 7.5cm and height is given 9cm. So by using the formula we get the above answer.
6 to 1
24:4 is simplified to
12:2
then 12:2 is simplified to 6:1, which is your final answer
