Answer:
<u>Hence final answer is B: Step 2.</u>
Step-by-step explanation:
Step 1: Find the total points needed to score in six games: 96x6=576
Justification:
Product of 96 and 6 is 576 which is same number found by Brenda. So step 1 is correct.
Step 2: Find the total points scored: 92+110+85+78=365
Justification:
Sum of total points scored by Brenda is 92+110+85+78= 461.
But she got different value 365.
Hence step 2 is wrong.
<u>Hence final answer is B: Step 2.</u>
Apply the "FOIL" method here. (m+1)(m+1) = m^2 + 1m + 1m + 1, or m^2 + 2m + 1.
Answer:
It will take the boulder approximately 4.28 seconds to hit the road
Step-by-step explanation:
The given height of the cliff from which the boulder falls, h = 90 feet
The equation that can be used to find the time it takes the boulder to fall is h = u·t + (1/2)·g·t²
Where;
h = The height of the cliff = 90 ft.
u = The initial velocity of the boulder = 0 m/s (The boulder is assumed to be at rest when it falls)
g - The acceleration due to gravity ≈ 9.81 m/s²
t = How long it will take for the boulder to hit the road below
Plugging in the values gives;
90 = 0 × t + (1/2)×9.81×t² = 4.905·t²
∴ t = √(90/4.905) ≈ 4.28
The time it takes the boulder to hit the road, t ≈ 4.28 seconds.
