Answer: total cost is $13
Step-by-step explanation:
Answer:
A = 200.96 sq ft
Step-by-step explanation:
formula for area of a circle: A = π·r²
A = (3.14)·(8²)
A = 64·(3.14)
A = 200.96
Answer:
Step-by-step explanation:
<u>Let the cost of daylilies = d and ivy = i, then we have below equations:</u>
- d + 12i = 114
- 10d + 10i = 150
<u>Simplify the second equation:</u>
<u>Subtract the second equation from the first:</u>
- d - d + 12i - i = 114 - 15
- 11i = 99
- i = 9, ivy costs $9
<u>Now find d:</u>
- d = 15 - 9 = 6, daylilies cost $6
Answer:
18
hope this helps
have a good day :)
Step-by-step explanation:
Step-by-step explanation:
as the velocity is not constant over time, we actually have to integrate v(t) over the interval 0<=t<=5 to get the distance.
v(t) = 60×ln(t + 1)
V(t) = 60 × integral(ln(t + 1)) between 0 and 5.
integral(ln(t + 1)) = (t + 1)ln(t + 1) - t + C
V(t) = 60 × ((t + 1)ln(t + 1) - t + C)
the distance traveled between t = 0 and t = 5 is then
60 × ((5 + 1)ln(5 + 1) - 5 + C) - 60 × ((0 + 1)ln(0 + 1) - 0 + C) =
= 60×(6ln(6) - 5 + C) - 60×(1ln(1) + C) =
= 60×(5.750556815... + C) - 60×C =
= 60×5.750556815... = 345.0334089... ≈ 345 km
