Answer:
this has happened to me before. unfortunately I had to refresh the page.
Step-by-step explanation:
write down the answers you already have done.
Change 4 feet to inches.
You need to know that for every
feet, there are 12 inches. So, if you have 4 feet, you just multiply 4 by 12
and you will get 48 inches. Note that the feet unit is larger than inches.
The solution to the quadratic equation by using a numeric approach
are x = 6.3 and x = -31.3
Given the quadratic function expressed as;
0.02x²+ 0.5x - 4 = 0
Multiply through by 100 to have;
2x² + 50x - 400 = 0
Using the general formula to solve:
x = -50±√2500-4(2)(-400)/2(2)
x = -50±√2500+3200/4
x = -50±75.49/4
x = -31.3 or 6.3
Hence the solution to the quadratic equation by using a numeric approach
are x = 6.3 and x = -31.3
