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: last option.
Step-by-step explanation:
You need to remember that a product is the result obtained by multplying the factors.
For example, in the following multiplication, the number 110 is the product and this is obtained by multiplying the factors 10 and 11:
Then, being 11 the product, then you can know that:
"x" is a factor and 5 is the other factor.
Therefore, the algebraic equation that could represent the sentence "The product of a number and five is 11", is:
Answer: 15
Step-by-step explanation:
max - min 15-0 = 15
Answer:
8.8 seconds
Step-by-step explanation:
Taking g = 9.81 m/s²
Convention: downwards positive
30 = -40t + 0.5(9.81)t²
4.905t² - 40t - 30 = 0
t = 8.846327763, -0.6913838279
t = 8.8s
