32% * 25 =
(32*25)/100
800/100=8
8%
Answer:
Step-by-step explanation:
think of the flight of a small rocket.. what does it seem like the parabola would look like? down means it looks like a cup or glass , upside down , up mean a cup or glass right side up.
when t = 0 the rocket is at 25, so that's the initial height
it's velocity is initially 200 m/s
put equation from std. form to vertex form
y = a
+ bx +c => y = a(x - h ) ^2 + k
h = -4.9
+ 200t + 25 =>h = -4.9(t - 20.41)^2 + 2,065.82
(h,k) = (20.41 , 2065.82)
I say A but you probably arnt gonna trust my answers again...gd luck!! xx
Answer:
I will show the way.
Step-by-step explanation:
r is the correlation coefficient
To find SSxy
SSxy= ∑
- ∑
To find SSxx
SSxy= ∑- 
∑x
/n
To find SSyy
SSxy= ∑
- ∑y/n
if your r is near +1, it shows strong positive correlation. Y is proportional to X.
And if it nears -1, it would show strong negative correlation. Y is inversely proportional to X.
Answer:
Step-by-step explanation:
↔Start of with your 'solution section' to make sure you have the right things↔
↔Solution 1 ➡ 4(x) + 9(y) = 16
↔Solution 2 ➡ 6(x) - 9(y) = 8
-----------------------------------------------------------------
▪Looking for the value of the 'x'-intercept ⬇▪
◾4 (3) (y) / 2 + 4/ 3 + 9(y) = 16
◾15(y) = 32 / 3
◾ 45(y) = 32
▪x-intercept: 32
-----------------------------------------------------------------
◾Looking for value of the 'y'-intercept ◾
◾45(y) = 32
◾y-intercept : 45
◾x = 3(y)/2+4/3 which is translated to this, am i correct? ➡ (y) = 32/45
-----------------------------------------------------------------
↪ Now, we have finally found both of their intercept ⬇
↪x-intercept: 12
↪y-intercept: 5
↪Or you can even say the intercepts in other words. Here's what I am talking about if in case you don't know what I am saying
↪x-intercept: 32✅
↪y-intercept✅
