The height of the project becomes zero when it hits the ground which is also the total time at which the projectile stays in the air. Equating the function to zero:
-10(x)(x - 4) = 0
The roots of this quadratic equation are:
x = 0, and x=4
Therefore, the projectile stays in the air for
4 seconds
Answer:
1.78 pints
Step-by-step explanation:
We need to find 4/5 of the total pints of paint she used, so we know how much blue paint she used. Then, we subtract that from the total pints of paint that she used.
She used 8.9 pints of both blue and white paint.
Therefore, the amount of blue paint she used is:
4 / 5 * 8.9 = 7.12 pints
The amount of white paint she used is therefore:
8.9 - 7.12 = 1.78 pints
9514 1404 393
Answer:
(x, y) = (2, 1)
Step-by-step explanation:
Use the second equation to write an expression for x:
x = 1 +y
Substitute that into the first equation:
(1 +y) +4y = 6
5y = 5 . . . . . . . . subtract 1, collect terms
y = 1 . . . . . . . divide by 5
x = 1 +1 = 2 . . . use the expression for x to find x from y
The solution is (x, y) = (2, 1).
Answer:
The F-Ratio increases as, the variability between means increases relative to the variability within groups
Step-by-step explanation:
The F-Ratio is given as follows;
Where;
= The variance between groups
= The variance within groups
Therefore, as the F-Ratio increases, the variability between groups (means) increases relation to the variability within groups
Answer:
7000
Step-by-step explanation:
lets start with 695
9 is the thousand
you check the number next to 9
less then 4 let it rest
more than 5 let it soar
something like that lol
anyways since 5 is next to the 9 we round up from 9 to the next number which is 10
so that changes the whole number to 7000
hope this makes sense!
