Answer:
2.4
Step-by-step explanation:
The area of a triangle is A=1/2b*h
You have the base (b) and you have the area (A)
So, if you plug in what you know, you get this:
45.5=1/2*10*h
Simplify it:
45.5=5h
Now solve for h
Divide by 5 to get h alone:
9.1=h
Your height is 9.1cm
Hope this helps :)
Answer:
f(x+5)=3x+16
Step-by-step explanation:
lets name " x+5" T
so f(T)=3T+1
now use "x+5" replace T
now its f(x+5)=3(x+5)+1=3x+15+1=3x+16
Answer:
The average velocity of the ball is 
Step-by-step explanation:
First find the velocities at given times and then form two points. Calculate the slope to find the average velocity. The two points are:

Answer: 2+(-35)
Step-by-step explanation:
When finding which equation is equivalent to the one you have. It's best to find what your equation's answer is.
2-35 equals -33
So we need to find the other equation that equals the same, for that's "equivalent". When you're trying to add a positive and a negative together, you're actually subtracting them because of the negative. In which your answer would end up as a negative, and if the negative is the greater number, you subtract it that way. Sometimes it's good to use a number line so you don't mess up if you're gonna go that way.
