Answer:
300 minutes
Step-by-step explanation:
60 minutes in an hour
5 hours
60x5 = 300
Answer: The answers are in the steps please look carefully.
Step-by-step explanation:
To solve for each value input the value into the function and solve to find f(x)
A. f(-3) = 2(-3)^2 + 2
f(-3) = 2(9) + 2
f(-3) = 18 + 2
f(-3) = 20
B. f(6) = 2(6)^2 + 2
f(6) = 2(36) + 2
f(6) = 72+ 2
f(6) = 74
C. f(-1) = 2(-1)^2 + 2
f(-1) = 2(1) + 2
f(-1)= 2 + 2
f(-1) = 4
D. f(4) = 2(4)^2 + 2
f(4) = 2(16) + 2
f(4) = 32 + 2
f(4) = 34
The inverse....switch ur x's and y's...
inverse :
domain is { -2,2,4,4,5} ...notice u have 2 "x" values that are 4
range is {-3,0,2,3,4}
The relation DOES NOT represent a function. A function will not have any repeating x values. It can have repeating y values, just not the x ones.
Now the relation would be a function...but the inverse is not
Answer:
A
Step-by-step explanation:
I think because I just had this similar problem if I'm wrong I'm sorry not a 100%sure just trying to help
Working alone Joan finish the job in 60 minutes, which means every minute she does 1/60 of the whole job.
suppose the sister can finish the job alone in x minutes, every minute she does 1/x of the whole job.
together they do (1/60 +1/x) part of the job every minute.
for 40 minutes they finish the whole job: (1/60 +1/x)*40=1 (1 represents the whole job)
40/60 +40/x =60/60
40/x=20/60
x=120
so it will take the sister 2 hours to finish the job alone
