Answer:
The total change in the altitude of the parachute after 4 minutes is 92 ft
Step-by-step explanation:
Here, we want to calculate the total change in the altitude of the parachute.
The rate of change per minute = 28 ft/m
Now in 4 minutes, the total altitude change will be;
28 ft/min * 4 min = 92 ft
In 4 minutes, there would have been a change of 92 ft in the altitude of the parachute
The speed is 66.33 miles per hour
Step-by-step explanation:
Given
Total distance = 325 miles
They still have 126 miles to go. In order to find the distance they have covered, we will subtract the remaining miles from the total
So,
![Distance\ covered=325-126=199\ miles](https://tex.z-dn.net/?f=Distance%5C%20covered%3D325-126%3D199%5C%20miles)
the car has been driving for 3 hours
So,
t= 3 hours
d = 199 miles
![Speed=\frac{d}{t}\\=\frac{199}{3}\\=66.33\ miles\ per\ hour](https://tex.z-dn.net/?f=Speed%3D%5Cfrac%7Bd%7D%7Bt%7D%5C%5C%3D%5Cfrac%7B199%7D%7B3%7D%5C%5C%3D66.33%5C%20miles%5C%20per%5C%20hour)
The speed is 66.33 miles per hour

Answer:
FV= $3,726.93
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $2,500
Interest rate (i)= 0.04/12= 0.003333 monthly
Number of periods (n)= x months
<u>To calculate the future value giving any number of months, we need to use the following formula</u>:
FV= PV*(1 + i)^n
<u>For 10 years:</u>
n=10*12= 120 months
FV= 2,500*(1.003333^120)
FV= $3,726.93
Answer:
y = 6x-4
Step-by-step explanation:
3x - 1/2 y =2
We need to solve for y to get the equation in slope intercept form
Subtract 3x from each side
3x-3x - 1/2 y =-3x+2
-1/2 y = -3x+2
Multiply each side by -2
-2*-1/2 y = -2*(-3x+2)
y = -2*(-3x+2)
Distribute
y = 6x-4
The slope is 6 and the y intercept (where it crosses the y axis) is -4
