Answer:
a=8, -8
Step-by-step explanation:
a^2-15=49
a^2=49+15
a^2=64
a=sqrt(64)
a=8, -8
11. 6÷5=$1.2 12. 50÷7.90= $6.32 13. 24÷2.95= $8.13 14. 200÷12=$16.6 15. 14.40÷4.5= $3.2 or (4.5÷14.4= 0.3125- Probably not the right answer, I just know it. :)) 16. 22÷2
= $8. Here are your answers! I hope they are right. :)

i dont know
Step-by-step explanation:
the domain of f(x)= x2 +1 is limited to {0,1,2,3)
the maximum value will be at the maximum value of x which is at x = 3
So, the maximum value of the range will be = 3^2 + 1 = 9 + 1 = 10
