Answer:
The maximum height of the projectile is 90 ft
Step-by-step explanation:
Here, we want to get the maximum height reached by the projectile
The answer here will be the y-coordinate value of the vertex form of the given equation
so firstly, we have to write the equation in the vertex form
We have this as;
y = -16t^2 + 64t + 26
That will be;
y = a(x-h)^2 + k
y = -16(x-2)^2 + 90
where the vertex of the equation is;
(-h,k)
K
in this case is 90 and thus, that is the maximum height of the projectile
Answer:
30
Step-by-step explanation:
Use PEMDAS
parentheses is first
3+7=10
There's no exponents
You have to do it in order from left to right
6÷2=3
3*10=30
Ok, let's find how much does 1 yard of ribbon cost. Let's divide!

Each yard costs $1.50, so let's multiply that by 10

Marci will pay $15 for 10 yards of the ribbon.
Your answer would be 3.75.
Answer:
-5
Step-by-step explanation:
