Multiply and divide by the product of the denominators.
Answer:
q=6
Step-by-step explanation:
Kim is X
Jordan= x+7
So J x 4=200
This means 4(x+7) = 200
x=43
43+7=50
50 x 4=200
so Kim is 43 and Jordan is 50.
Answer:
the ball is in the air for 8 seconds
Step-by-step explanation:
f(x) = y
when y = 0, the ball would've travelled through the air over the final time of flight.
0 = -5x^2 + 40x + 0
use quadratic equation to find the value of x
x = (-b ± √b^2 - 4 • a • c) / 2 • a
x = (-40 ± √40^2 - 4 • -5 • 0) / 2 • -5
x = (-40 ± √1600) / - 10
x = (-40 ± 40) / - 10
x = 0 or x = 8
About 127.156 its not exact but instead of 2850 miles i used 2849.52 miles so tell me if thats fine
