-1302f2x also the 2 after f is a tiny 2
Answer:
The answer is Ari, Beth, Cindy
Explanation
Ari
- 2¾ miles is 2.75 miles
- speed of 2½ miles per hour is 2.5 mi/h
DISTANCE = SPEED × TIME
t = d/s
= 2.75/2.5
= 1.1hr
= 66mins
Beth
- 1¾ miles is 1.75 miles
- speed of 1¼ miles per hour is 1.25 mi/h
t = d/s
= 1.75/1.25
=1.4hr
=84mins
Cindy
(Correct me if i am wrong)
F(x)=-2e^x
x=3
f(3)=-2e^3
pemdas so exponents first
e^3
e=2.718281828454590
cube that
20.0855
now we have
-2 times 20.0855=-40.1711
answer should be -40.1711
(I see what you did wrong, if -6=-2 times e^3, divide -2, 3=e^3, maybe you just put -2 times 3 by mistake)
Answer:
See below
Step-by-step explanation:
IN a right triangle , remember S-O-H-C-A-H-T-O-A <===memorize this!
sin z = O/H = opposite side/hypotenuse = 16/20
cos z = A/H = adjacent / hy[potenuse = 12/20
tan z = O/A = 16/12
The answer is 6.601, and therefore, the second option.
