Answer:
no
Step-by-step explanation:
9514 1404 393
Answer:
3 seconds
Step-by-step explanation:
We want to find t when h=0.
0 = 2t² -5t -3 . . . . . . . divide by -8
0 = (2t +1)(t -3) . . . . . . factor
The values of t that satisfy this equation are the values that make the factors zero: t = -1/2, t = 3. The positive value is the one of interest.
It takes 3 seconds for the object to hit the ground.
C. 6 + 7 = 13
<span>This is because 33, 21, and 15 are composite numbers, and 13 is not.</span>
15. 2x-5=-20
2x=-15; Add positive 5 on both sides to isolate x.
x=; Divide 2 on both sides to find the value of x.
17. =-9
9x=-36; Multiply positive 4 on both sides of the equation.
x==-4; Divide 9 on both sides of the equation to find the value of x.
