Answer:
1,3,5
Step-by-step explanation:
-16t^2 + v0t + h0
= -16(t^2 - 1/16 v0t) + h0
= -16 [(t - 1/32v0)^2 - (1/32 v0)^2 ) + h0
= -16(t - 1/32v0)^2 + 1/64 (v0)^2 + h0 which is the vertex form
The vertex is at the point (1/32v0, 1/64 (v0)^2)
1/32v0 represents the time when the firework is at its maximum height and 1/64 (v0)^2 is this maximum height
To solve these you have to follow the orders of operation(BEDMAS), which means brackets, exponents, division, multiplication, addition, subtraction all in that order.
A) This is false. 7x6+4=46 and does not equal 7x10 or 70.
B) This is false as well. The answer haste be 19 and 16-(4+7) does not equal 19. You add up what is in the brackets first and then subtract.
This means that C and D have to be true.
C) 10+(6/3)=12
10+2=12 True
D) 2+5x7=37
2+35=37
Also true
Answer:
Step-by-step explanation:
First, move the -11/4 to the other side, so the expression can equal 0.
To make the equation easier to work with, multiply both sides by 4, cancelling out the fraction.
There are many ways to solve a quadratic equation (factoring, quadratic formula, completing the square).
Solving this equation by factoring is the easiest. Factoring with a leading coefficient greater than one can be difficult and there are many ways to accomplish it. The way I'm going to do it is to first find the factors of 
and then the factors of 11. And then multiply across, add the middle terms (derived from multiplying) and try to make it equal 24x.
: 24x 11:
2x 22x 11
2x 2x 1
24x (works)
I'll then take the factors diagonal. (2x+1)(2x+11)=0
So 
Answer: you have a 50/50 chance of getting it right, so basically the number would be 385. half of 770 is 385.
