Answer:
B
Step-by-step explanation:
Given
y = a(x - h)² + k ( subtract k from both sides )
y - k = a(x - h)² ← divide both sides by (x - h)²
= a → B
<span>the equation is -16t^2+150t+50, the middle term being the upward velocity and the last term being the height it started at.
The vertex is at -150/-32=4.6875, and the height is 401.56 feet
Setting the equation equal to zero,
-16t^2+150t+50=0 or 16t^2-150t-50=0
t=(1/32) { 150 +/- sqrt (22500+3200)}, where sqrt (25700)=160.31
t=(1/32)310.31=9.697 sec or 9.7 seconds TIME TO LANDING

n-p for the first, p-n for the second
Step-by-step explanation:
Answer:
B and D are both true statements
Step-by-step explanation:
A is false. The ratio of green pieces to blue pieces is 7:5 is false as the statement tells us total is 12 when green is 5. This means total is 12.
In the A. statement, it describes green pieces to blue pieces, where blue pieces are more than 5, its order in A states 5 last, meaning blue=5 and this is not true.
B is true. This speaks of the total pieces to blue pieces is 12:7 this is true as it speaks of total first = 12. where blue is also =7. This is true.
C is false. There must be 7 more blue pieces than green pieces this is false as there are two (2)more blue pieces than green, not 7.
D is true. The ratio of total pieces to green pieces is 12:5 is also true as there are 12 total and 5 green and it states this in same order within the statement showing the reverse of the statement in the question where green still is 5 and total is 12.
