Answer:
hope this helps!
Step-by-step explanation:
From y(t) = −16t^2 − 3t + 300 find at what time the fertilizer hits the ground (has height 0)
0 = −16t^2 − 3t + 300
Using the quadratic formula (minus b plus or minus the square root of b squared minus 2 a c over 2 a) you get
t = 4.237 seconds
So the horizontal distance is 85t = 85 * 4.237 = 360.145 feet
4+3+1+1+1+1+1 =12
4x3x1x1x1x1x1=12
This question is an example of d = r * t
r = rate
r = 3*10^8 m/s
t = ??
d = 7.5 * 10^6 meters.
Sub and solve
d = r * t
7.5 * 10^6 = 3 * 10^8 * t Divide both sides by 3 * 10^8
7.5 * 10^6 / (3 * 10^8) = t
2.5 * 10^(6 - 8) = t
2.5 * 10^-2 seconds = t or
0.025 seconds = t
Answer: moderate positive correlation
Step-by-step explanation: If your correlation coefficient is positive, that means that your slope which is how steep the line is or your line of best fit must also be positive.
Remember that the correlation coefficient is just a number that indicates the direction and closeness of points of a line of best fit.
If it has a correlation coefficient of 0.89, the points would be close together but not very very close.
