Answer:
0.8632
0.8696
Step-by-step explanation:
Your answer is accurate, but it's not the most precise option.
f(x) is decreasing and concave up on the interval. Therefore, trapezoidal rule will give us an area greater than the actual area, but closer than left-hand rule.
If f(x) were a straight line, then midpoint rule would give us the same area as trapezoidal rule. However, since f(x) is concave up, the midpoint is less than the average of the endpoints. So midpoint rule will give us an area less than the actual area, but closer than right-hand rule.
Answer:
54000-65000
Step-by-step explanation:
round the numbers first down to 1200 and 45, and multiply, then round up for the larger, like 1300 and 50 to get your answer.
B). (-6,-7)
Hope this helps! Please make me the brainliest, it’s not necessary but appreciated, I put a lot of effort and research into my answers. Have a good day, stay safe and stay healthy.
The formula for the sum of geometric series = a (1 - r^n) / 1 - r
when it will be an infinite geometric series. the term r^n will equal to zero because and number < 1 that is raise to the power infinity the answer is zero that is why in a infinite geometric series, sum = a / 1 - r.
if the r < 1 then there will be no numerical answer because the sum will be infinity. that is why r < 1 to have a sum
Answer:
-7x - 6
