The 4 subintervals are given: [2, 4], [4, 7], [7, 9], and [9, 10].
Each subinterval has length: 4 - 2 = 2, 7 - 4 = 3, 9 - 7 = 2, and 10 - 9 = 1.
Over each subinterval, we take the value of the function at the right endpoint: 3, 8, 15, and 18.
Then the integral is approximately

so 78.0 is the correct answer.
Answer:
Enough water has been poured .
Step-by-step explanation:
The garden needed water in a week = 5 liters
Jacob poured water on Monday = 326 ml = ( 326/ 1000) liters = 0.326 liters.
SEAN poured water on Tuesday = 1.5 liters
Gavin poured water on Wednesday = 2312 ml = ( 2312/ 1000) = 2.312 liters.
Stephen poured water on Thursday = 894 ml = ( 894/ 1000) = 0.894 liters
The total amount of water poured by all these people = 0.326 + 1.5 +2.312 +0. 894 = 5.032 liters
Here we can see that water has been poured is more than the water required in a week.
∠B = 52°
Since the triangles are similar then
∠C = ∠S = 56°
∠B = 180° - (72 + 56)° = 52°

The answer 850709 is
6
because
if there is $48 to spend on the event and it costs $8 for each attendee, divide 48 by 8 to get 6.
