Answer:
B
Step-by-step explanation:
Answer:
It will take 22 seconds for the thermometer to hit the ground.
Step-by-step explanation:
A thermometer falls from a weather balloon at a height of 7,744 ft.
This means that the initial height is of 7744ft.
h(t) = -16t2 + initial height
So

How many seconds will it take for the thermometer to hit the ground?
This is t for which
. So





It will take 22 seconds for the thermometer to hit the ground.

Okie, so you have an whole number subtracted by a fraction of a number. The way to approach this problem is to convert whole number to the LCD (least common denominator) of the fraction. In this case it would be 6.
6 would be 36/6 (same number just different form)
now just subtract the numerators over the denominator
(36-1)/6 = 35 / 6 is your answer as an improper fraction. As a mixed number, it would be 5 5/6.
I hope this helps :-)
Since we know the slope is 3 we have part of the equation already (y=3x+b). Now we need to find the y-intercept. To do that we plug in the point that was given to us in the question and solve for b.
0=3(-5)+b
0=-15+b
15=b
Now that we have the y intercept we can put the equation together.
Answer: y=3x+15
Hope this helps :)
