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.
Step-by-step explanation:
if two have the same shape, they are called "similar". When two figures are similar, the ratio of the lengths of their corresponding sides are equal. To determine if the triangles show are similar, compare their corresponding sides. Triangles ABC is similar to triangle DEF.
Answer:
178,920
Step-by-step explanation:
The trick is both the set up and keeping your columns in line
1
4 2 0
<u>x 4 2 6</u>
2 4 2 0 multiply 6 by each number on top, carry the 1 over
8 4 0 0 use left zero as place holder and multiply each # by 6
<u>+ 1 6 8 0 0 0</u> use left 2 zeroes as place holders and multiply each # by 4
1 7 8,9 2 0 add all the columns up to get your answer
It would be simplified to 20
Answer: After 12 weeks they will both be at the dentists on the same Tuesday
Step-by-step explanation:
Since we have given that
He goes for a checkup every fourth Tuesday and his friend goes for a check up every third Tuesday.
We need to find the number of weeks they both will be at the dentist on the same Tuesday.
For this we will find "L.C.M. of 4 and 3 " =12
So, After 12 weeks they will both be at the dentists on the same Tuesday.
