Yes, I'm getting C also!
Since it's asking for the left-endpoint Riemann Sum, you will only be using the top left point as the height for each of your four boxes, making -1, -2.5, -1.5, and -0.5 your heights. The bases are all the same length of 2. You don't include f(8) because you're not using right-endpoints, and that would also add another 5th box that isn't included in the 0 to 8 range.
Answer: -3/2
Step-by-step explanation:
The axis of symmetry, and thus the x-coordinate of the vertex, is given by 
So, the answer is 
Is there a math question and can you show it please
I am assuming that you are supposed to answer this division problem through the long division method. So my answer is going to be a step-by-step description of the long division solution for this problem.
The first step is to move the decimal point of the dividend and the divisor. Hence, 1264.0 and 17. The decimal point of the quotient shall then be written in alignment with the decimal point of the dividend.
Then we proceed with the division process, 126/17 gives us 7 (write this above the division bar). 7 multiplied by 17 gives 119 (write this under the divisor). So 126-119 is equal to 7. We then bring down the digit after 126 of the divisor, which is 4. So we now have 74. 74 divided by 17, we get 4. 4 multiplied by 17 gives 68. We subtract 68 from 74 and we have 6, bring down 0, we have 60. We then repeat the division-multiplication-subtraction process until we get to the third decimal place of the quotient.
Finally, the answer is 74.352.
