Points (-3, 5) and (-2, -7)
A) 12x + y = -31
12(-3) + (5) = -31
-36 + 5 = -31
12(-2) + (-7) = -31
-24 - 7 = -31
The answer is A
<span>h= (-16t^2 + 28t + 7) </span>
find the derivative to get time<span>
<span>
h' = (-32t + 28)
When the ball reaches its maximum height, its
vertical velocity (h’) will be 0 </span></span>
<span>
<span>
0 = -32t + 28 </span></span>
-32t=-28
<span><span>-28/-32 = </span>0.875
seconds </span><span>
<span>
The ball reaches its maximum height in 0.875
seconds after being thrown; plug and chug and:
h= (-16(0.875)^2 + 28(0.875) + 7) = 19.25 feet</span></span>
Max height = 19.25 feet, time = 0.88 seconds
Assuming there are 6 purple marbles, there would be 0 white marbles added. If there are not 6 purple marbles, please let me know so I can help.
Answer: a=1 b=-4
Step-by-step explanation:
Apply the equation y= a^2+bx+c
There are 25 = 32 possible outcomes.
