Answer:
2:20PM
Step-by-step explanation:
3:45 - 1 hour = 2:45 (drive)
2:45 - 25 minutes = 2:20
2:20pm
Answer:
The base = 8 cm and the altitude = 4 cm.
Step-by-step explanation:
b = a + 4 where b = base and a = the altitude.
Area = 1/2 * a * b = 16
Area = 1/2 * a * (a + 4) = 16
1/2 a^2 + 2a = 16
a^2 + 4a - 32 = 0
(a + 8)(a - 4) = 0
a = 4 .
b = 4+4 = 8.
Answer:
Step-by-step explanation:
We are to integrate the function

over the area enclosed by the circle

Convert into polar coordinates

x=rcost and y = rsint
Since the lines are x=0 and y=x we find that t varies from 0 to pi/4

Double integral will become now

(since variables are independent here)
Substitute for r and t
4 sin pi/4 -2 cospi/4
= 
I feel like it would be 60 but I could be wrong

Step-by-step explanation:
Similar polygons. Only side lengths change; the angles remain the same through dilation.
