Answer:
5000 x 10 x 10 x 50 = 25000000
Step-by-step explanation:
you can just use a calculator....
Step-by-step explanation:
Given:
- when s = 12 mph t =0.18 let (s,t) or (a,b) = (12,0.18)
- when s = 22 mph t = 0.23 s (s,t) or (a,b) =(22,0.23)
- when s = 30 mph t = 0.15 s (s,t) or (a,b) =(30,0.15)
<u>we know the general format of Quadratic equation to be </u>
<u>= </u><u>ax²+bx+c=0</u>
<u></u>
<u>Step 1</u> :
when the birds pass through a,b (12,0.18) we cane give the expression as
= ax²+bx+c=0
= 12x² + 0.18x + c= 0
it can also be written as
<u>s = ut + 1/2 at²</u> = 0.18t +( 1/2) a(0.18)²
<u></u>
<u>step 2 :</u>
through points (22,0.23)
= 22x² + 0.23x + c = 0
<u>s = ut + 1/2 at²</u> = 0.23t + (1/2) a(0.23)²
<u>Step 3 :</u>
through points (30,0.15)
= 30x² + 0.15x + c = 0
<u>s = ut + 1/2 at²</u>
= 0.15 u +(1/2) a(0.15)²
