From the information: v is 64 while c is 5
Differentiate the new equation h=-16
+ 64t + 5 to get 
= -32t + 64.
no 13). At maximum height this derivative equals zero so: -32t + 64 = 0; -32t = -64; t=2.Hence ans is 2 secs
no 14). put t as 2 sec in the equation: h=-16 + 64t + 5. This gives
h=-16( 
) + 64(2) + 5; h=-64+128+5=69. Hence h is 69ft
Answer:
Step-by-step explanation:
<u>The quadratic equation in factored form:</u>
- a(x - α)(x - β), where a- leading coefficient, α and β - roots
<u>We have:</u>
<u>Substitute them to get:</u>
<u>Converting this into standard form:</u>
- 3(x - 1)(x + 2) =
- 3(x² + x - 2) =
- 3x² + 3x - 6
Answer:
I found it! It's over here!!
Now what do I do with it?
Marbles in a bag: 3 green, 4 yellow, 5 blue, 8 pink.
Event A - get a green or yellow marble
Event B - get a pink marble
Events A and B are independent because we draw a marble from a bag with 20 marbles in both cases.
Probability of combined events is
2*(X-2+3x+5)=94 cm
4x+3 = 47
4x=44
x=11 cm
