Answer:
x=-22/3
Step-by-step explanation:
Answer:
a=4
c=5
e=7
f=1
Step-by-step explanation:
the simplest method would be to start with a(2)"squared" (being '4' as this will get you closest to 15. So 16 -1 (being 'c') = 15. now plug those into the other equations and work the other numbers out.
Answer:
A. 0.72
Step-by-step explanation:
When the ball hits the ground, h = 0.
0 = -16t² + 6t + 4
0 = 8t² − 3t − 2
Solve with quadratic formula:
t = [ 3 ± √(9 − 4(8)(-2)) ] / 16
t = (3 ± √73) / 16
t = 0.72
We presume you want to find the number.
Let n represent the number.
6 + n/4 = 3 . . . . . . . 6 more than the quotient of a number and 4 is 3.
To solve this, we "undo" what is done to the number. First we undo the addition of 6 by adding its opposite, -6. We add -6 to both sides of the equation so the equal sign remains valid.
6 -6 +n/4 = 3 -6
n/4 = -3 . . . . . . . . simplify
Now, we need to undo the division by 4. We do that by multiplying by 4. Again, we must do that to both sides of the equation so the equal sign remains valid.
4(n/4) = 4(-3)
n(4/4) = -12
n = -12
The number is -12.
There are 60 secs in every minute. 60 x 18 = 1080 seconds
