Answer:C
Step-by-step explanation:
3.1 x 10^(-4) x 8.5 x 10^(-2)
3.1 x 8.5 x 10^(-4) x 10^(-2)
26.35 x 10^(-4-2)
26.35 x 10^(-6)
2.635 x 10^1 x 10^(-6)
2.635 x 10^(1-6)
2.635 x 10^(-5)
ANSWER
5
EXPLANATION
The equation that expresses the approximate height h, in meters, of a ball t seconds after it is launched vertically upward from the ground is

To find the time when the ball hit the ground,we equate the function to zero.

Factor to obtain;

Apply the zero product property to obtain,


t=0 or t=5.1 to the nearest tenth.
Therefore the ball hits the ground after approximately 5 seconds.
Answer:
A and E
Step-by-step explanation:
9^3 / 9^3
Same number on top and bottom so 1 is an answer
look at the exponents, when dividing with exponents, you just subtract them, so it could also be 9^0, which is also 1
Solution:
Let's name the three consecutive numbers as y, y + 2, and y + 4.
<u>Note that:</u>
- => Equation formed: 3(y) = 2(y + 4)
<u>Solve the equation to find the three consecutive numbers.</u>
- 3(y) = 2(y + 4)
- => 3y = 2y + 8
- => 3y - 2y = 8
- => y = 8
The numbers are 8, 10, and 12.
6b<42
b<7
4b+12>8
4b>-4
b>-1
b>-1 or b<7
