Answer:
Therefore it will take 
s for the object to reach the ground.
Step-by-step explanation:
Given function is
H(t) = -64 t²+169.
where H is height in feet, and t is time in second.
When the object touches the ground, the height of the object will be zero.
i.e H(t) = 0.
Therefore
H(t) = 0
⇒ -64 t²+169=0
⇒ -64 t²= -169
[ square root both sides]
Time can not be negative.
Therefore 
Therefore it will take s for the object to reach the ground.
Since a tax of 4% would be added to the cost price,
The total percentage = 100% + 4% = 104% of the cost
= 104% of 940
= (104/100) * 940
= 1.04 * 940
= 977.6
Total price = $977.60
The answer would be k = -89
Answer:
Slope: -1/2
y-intercept: 7
Step-by-step explanation:
The slope is the interger/number in front of x in a linear equation.
y-intercept is the constant after the slope, 7, which is the value of y when x is 0.
