you know that (0,3) is a point and (1,1) is another point.
so now you have to replace them in the follow equations.
i did that and the right answer is the first equation => y=-2x+3
Tax= 85 times 7% = 85 times 0.07
tax =85 times 0.07 = 5.95
tax = 85 = 5.95 2= 90.95
the answer is 90.95

Answer:
c
Step-by-step explanation:
<u>We are given:</u>
The function: y = -16t² + 64
where y is the height from ground, t seconds after falling
<u>Part A:</u>
when the droplet would hit the ground, it's height from the ground will be 0
replacing that in the given function:
0 = -16t² + 64
16t² = 64 [adding 16t² on both sides]
t² = 4 [dividing both sides by 16]
t = 2 seconds [taking square root of both sides]
<u>Part B:</u>
for second droplet,
height from ground = 16 feet
time taken = t seconds
acceleration due to gravity = 10 m/s²
initial velocity = 0 m/s
h = ut + (1/2)at² [second equation of motion]
16 = (0)(t) + (1/2)(10)(t²)
16 = 5t²
t² = 16/5
t = 1.8 seconds (approx)
Therefore, the second droplet takes the least amount time to hit the ground
