Answer:
C) Both procedures are correct
Step-by-step explanation:
1 + tan²(theta) = sec²(theta)
And
cos²(theta) = 1 - sin²(theta)
Are both valid identities
Answer:
4.50
Step-by-step explanation:
sin 40°= opposite/hypotenuse
sin 40°= opp/7
0.6428= opp/7
multiply both sides by 7
4.4996= opp
to nearest hundredth = 4.50
Answer:
0.5 ft per min
Step-by-step explanation:
in 80 minutes the radius expanded by 40%
we can set up a proportion of percent change over minutes:
.4/80 = r/1
cross-multiply to get:
80r = .4
r = .005 or 1/2 of a foot per minute.
Hope It Helps :)
K + a + h = 50
a = 2h
k = h - 10
(h - 10) + 2h + h = 50
4h - 10 = 50
4h = 50 + 10
4h = 60
h = 60/4
h = 15 <=== Henry sent 15
a = 2h
a = 2(15)
a = 30 <=== Aldo sent 30
k = h - 10
k = 15 - 10
k = 5 <=== Keiko sent 5
Answer: Here is the explanation. also it it +3y not -3y
Step-by-step explanation:
x+y+4+2y+1=x+3y+5 because
2y+y=3y
so now you have x+3y+4+1
4+1=5
now you have: x+3y+5
if you do not understand, What i am trying to say is, you need to add all of the same things.
