ok sorry

Answer 16

4. A ball is thrown and it follows a parabolic path. At each horizontal distance (x) the following equation models the balls height (y)
Y=-0.02x^2+0.8+3
what will the height of the ball be at a distance of 10 feet
6
7
8
9

Answer 17

How did you find #2?

Answer 18

first put x=0 in all equ. in which you find y=1 is right one there are two equations for it
then put x=1 if you find y=1 is the right option

Answer 19

que.. 4 is wrong

Answer 20

Oh cool thank you. Do you know #4?

Answer 21

what do you mean?

Answer 22

mins it's ans. is 1.8

Answer 23

There is no other way to get a different answer?

Answer 24

ok then check que. once again

Answer 25

\[Y=-0.02x ^{2}+0.8+3\]

Answer 26

sry then i can't find it's answer

Answer 27

thats fine I have 7 more if you could help with those? please @vipul92

Answer 28

5. what is the standard form of the equation? y=(x+2)^2-3

Answer 29

it's c

Answer 30

Answer 31

@vipul92

Answer 32

c

Answer 33

How did you solve that?

Answer 34

@vipul92

Answer 35

sry ans. is d first

Answer 36

x^2 + 12x + 2x + 24

Answer 37

x(x+12)+2(x+12)
(x+12)(x+2)

Answer 38

ok now do ownself

Answer 39

can you walk me through it?

Answer 40
