Answer:
34,000
Step-by-step explanation:
0.06(17,000) + 0.03b = 0.04(b + 17,000)
1020 + 0.03b = 0.04b + 680
0.04b-0.03b=1020-680
0.01b = 340
b = 34,000
First is 7 second is 8 third is 3
Answer:
Step-by-step explanation:
This is information that is modeled by a parabolic equation. The leading coefficient is -16t^2 because we are in feet as opposed to meters (which would be -4.9t^2). The standard form of this parabolic motion is
where s(t) is the height of the baseball after a certain amount of time has gone by, v0 is the initial vertical velocity, and h0 is the initial height. Filling in what we have:
We are asked when the ball hits the ground. If s(t) is our position after a certain time has gone by, and the height of the ball on the ground is no height at all (or 0), then replace s(t) with 0 and factor to solve for t.
Throw that into the quadratic formula or however you like to factor second degree polynomials, and get that the 2 solutions are that
t = -.12 seconds and that t = 1.56 seconds. We all know that time will NEVER be negative, so the time we want is 1.56 seconds, choice C.

Answer:
340
Step-by-step explanation: 200 * .14 = 28 then 28*5= 140 then 140+200=340
