Answer:
f(7) = 158
Step-by-step explanation:
To evaluate f(7) substitute t = 7 into f(t)
f(7) = 3(7)² + 11 = (3 × 49) + 11 = 147 + 11 = 158
Answer:
22x+10y
Step-by-step explanation:
15x + 2y + 7x + 8y ----> 22x+10y
Answer:
R-{13}
Step-by-step explanation:
We are given that


We have to find the domain of fog(x).



Domain of f(x)=R
Because it is linear function.
Domain of g(x)=R-{13}
Because the g(x) is not defined at x=13
fog(x) is not defined at x=13
Therefore, domain of fog(x)=R-{13}
Given:
No of users in February is 45,000 and in october its 60,000.

t=2




Therefore, approximate no of users after 2 years is 106667.
This would be C. 60$
This is because if she got the bag for 50% off, 30 divided by 2 is 15$, 45 divided by 2 is 22.5, 60 divided by 2 is 30$ so option C. Would be your answer.
