x=3/16
But knowing just the answer is not a good idea. Learn how to solve it. Jedimath on ipad can teach you.
Answer:
b=36
Step-by-step explanation:
by triangle exterior theorem
b+81 = 117
b=36
Answer:
1) h(t) = -5(t-3)^2
2) The ball reaches the highest point at 3 seconds.
Step-by-step explanation:
OK. So for this question, I recommend to rewite using vertex form since the answer is given in a more concise manner than using factored.
First Step:
h(t) = -5t^2+30t
= -5(t^2-6t)
= -5(t^2-6t+9)+45
= -5(t-3)^2+45
Second Step:
The vertex form reveals the vertex to be at (3, 45).
Therefore, the ball reaches the highest point at 3 seconds.

Therefore you need 4 batches of cupcakes if you want <u>every person to get one cupcake</u>.
- This means you multiply the amount of salt <em>per batch</em> by the number of batches, to get the total amount of salt you need.
- Each batch contains <em>1 teaspoon of salt</em> for 21 cupcakes. Multiply:
for the whole thing.
