Which are the solutions of the quadratic equation?
Given: x2 = 7x + 4
x2 = 7x + 4
0 = -x2 + 7x + 4
Answer: x = (7 + √33) / 2
X in (-oo:+oo)
x+5/12 = 5/8 // - 5/8
x+5/12-(5/8) = 0
x+5/12-5/8 = 0
x-5/24 = 0 // + 5/24
x = 5/24
x = 5/24
Answer:
$32.55
Step-by-step explanation:
8.95 + c = 41.50
subtract 8.95 from 41.50 to get 32.55
this makes c = 32.55
so the cost of the sandals is $32.55
H=-16t^2+49
find where h=0
0=49-16t^2
0=7^2-(4t)^2
difference of 2 perfect square
0=(7-4t)(7+4t)
set to zero
7-4t=0
7=4t
7/4=t
7+4t=0
4t=-7
t=-7/4
faslse, this is before the person jumps
answer is 7/4 seconds
610,000 in scientific notation is: 6.1 x 10^5
