Answer:
-2 is the answer!!!!hope this helps
This composite figure consists of a right triangle and semicircle
The area of a triangle is: 1/2(bh)
The area of a semicircle is 1/2(pi)(r²)
Plug in the values:
1/2( 12)(8)
=48
1/2(3.14)(4²)
=25.12
25.12+48=73.12
Hope this helped :)
It is the first one, the second one, and the fourth one.
Hope this helps ;)
A) time = distance/speed
For the first half of the trip, the time used was
.. (1 mi)/(12 mi/h) = (1/12) h = 5 minutes
Then the last half of the trip took 10 minutes, 1/6 hour.
.. speed = distance/time
.. = (1 mi)/(1/6 h) = 6 mi/h
The speed for the last half of the trip was 6 mph.
b) The average speed was
.. (2 mi)/(1/4 h) = 8 mi/h
Ling's average speed was 8 mph.
Answer:
15. -2 16. 0 17. undefined
Step-by-step explanation:
Slope of two points can be calculated by (y change) / (x change).
(y1 - y2) / (x1 - x2)
15) (1-5) / (4-2) = -2
16) (6-6) / (1-10) = 0 since y change is 0.
17) (-5-3) / (4-4) = undefined since x change is 0 but you cannot devide by 0.
