Answer:
The diver will be in free fall for 
seconds.
Step-by-step explanation:
The distance in feet, that an object falls in t seconds is given by the function 
.
Now, given that the height is 4800 feet and we have to calculate the number of seconds the diver was in a free fall.
Therefore, 
⇒ 
⇒ 
seconds.
Therefore, the diver will be in free fall for seconds. (Answer)

Answer:X + Y ≥ 4
$2.20X + $2.95Y ≤ $10.00
Strawberries cost $2.20 per pound
Raspberries cost $2.95 per pound
Jada only has $10.00 to spend
She wants to buy at least 4 pounds
Assumption: She buys X pounds of strawberries and Y pounds of raspberries.
<u />
<u>Solution:</u>
Number of pounds can't be less than 4
i.e X + Y ≥ 4
The cost of buying strawberries and raspberries has to be $10.00 or less than $10.00
i.e $2.20X + $2.95Y ≤ $10.00
So the system of equations is;
X + Y ≥ 4
$2.20X + $2.95Y ≤ $10.00

Answer:
The gradient is 3/7 make y the subject. Then put the coordinates in the equation.
Step-by-step explanation:
Answer:
<h2>x = 40</h2><h2 />
Step-by-step explanation:
fx=2x-50
Find x when fx=30
30 = 2x - 50
add 50 each side
30 + 50 = 2x - 50 + 50
80 = 2x
x = 80 / 2
x = 40
