Answer:
9x^2 + 15x -6
Step-by-step explanation:
Your problem → If f(x) = x^2 + 7x and g(x) = 3x - 1, find f(g(x))?
f(x)=x2+7x,g(x)=3x-1,fog(x)=?
g(x)=3x-1,f(x)=x2+7x
fog(x)=f(g(x))
=f(3x-1)
=(3x-1)2+7⋅(3x-1)
=(3x-1)2+21x-7
=(9x2-6x+1)+21x-7
=9x2+15x-6
fog(x)=9x2+15x-6
Answer:
8 hours
Step-by-step explanation:
after 8 hours chance will have traveled 100 miles and malik will have traveled 102 miles.
If the radius for the whole circle is 8 then half of it would be four. But if half of the circle is 8 then it would be 16pi for circumference if that's what you're trying to find.
Answer:
11
Step-by-step explanation:
Distance between K and P
Distance = square root of[ (5-1)^2 + (6-(-4)) ]
Distance = square root of [ 4^2 + 10^2 ]
Distance = square root of 116
Distance = 11
