Answer:
it will take 5.5 seconds to hit the ground
Step-by-step explanation:
A projectile is shot vertically from the ground level. It’s height h, in feet, after t seconds is given by 
When the projectile hits the ground then the height becomes 0
GCF is -8t
now set each factor =0 and solve for t
So it will take 5.5 seconds to hit the ground
Think of this situation as a system of equations.
let y be the price of hotdogs
let x be the price of hamburgers
5y + 2x = 8
2y + 5x = 9.50
now use your solution method of choice
substitution, elimination, matrices, etc
Answer: During the second hour it could travel either 4,5,6,7,8,9 hours
Step-by-step explanation:
Answer:
The answer is y= -4x-14
Step-by-step explanation:
y= 1/4x - 7 (-2, -6)
y=1/4x - 7
y=mx+b
y=-4/1x+b
-6=-4(-2)+b
-6=8+b
-8 -8
-14=b
Answer:
$18,432
Step-by-step explanation:
After the first year, the speedboat is now worth $36,000 because 20% of 45,000 is 9,000, and 45,000 - 9,000 = 36,000. After the second year, it is now worth $28,800. After the third year, it is worth $23,040 since 20% of 28,800 is 5,760 and 28,800 - 5,760 = 23,040. After four years, the boat that once was worth $45,000 is now worth $18,432.
