Answer:

V0 = 48 feet per second is the answer.

Step-by-step explanation:

The given function which represents height of a golf ball in feet after x seconds after a player hits it.

y = -16x² + v0x

here v0 is the initial velocity and we have to calculate initial velocity. The ball returns to the ground 3 seconds after it is hit.

After 3 seconds height of the ball will be 0.

Now from the given function

0 = -16(3)² + v0×3

3v = 16×9

v0 = 16×9/3 = 48 feet per second.

Simplify the following expression
shepuryov [24]
The Answer would be 2.8 because when you subtract -16 - 8 you get -24... then you divide that by 2 and you should have -12 + 25 / 5 + 1.... from there you can move the one from the end and add it to 25 and you get -12 + 26 / 5.... and all you have to do is simple math there... -12 + 26 = 14... and 14 / 5 == 2.8

ANSWER == 2.8

Select all that apply to the following statement. There is a LOW correlation between cheating and final grades in Math256. Group
Gwar [14]

Answer:

The correlation has no unit of measurement; it is just a number.

Correlation requires both variables to be quantitative.

Step-by-step explanation:

Correlation refers to the measure of the relationship between two variables. The correlation between two variables is measured using the correlation Coefficient which may take any value between - 1 and 1 ; the closer the correlation Coefficient is to either 1 or - 1, the greater the relationship with negative depicting a negative association and positive depicting a positive relationship between the variables. The correlation Coefficient requires that both variables are numeric (quantitative). The correlation Coefficient has no unit of measurement.

Noah said, “When you divide a number by a second number, the result will always be smaller than the first number.”
marshall27 [118]

Answer:

When dividing two fractions by each other, the result will be larger. Dividing two whole numbers, however, will always result in a smaller number because you're taking away a part of the number.
