45/5 = 9minutes/wall = 1wall/9minute/4 people = (1/36) per minute per person
(1/36)*6 = 1/6 wall per minute per 6 people * 24 = 4 walls in 24 minutes
24 Minutes total
Answer:
{ln 4, (2 + 2e^ln 4 − 4 ln 4)} or (1.39, 4.45)
Step-by-step explanation:
From this equation 4x − y = 3
-y = 3 - 4x
then, y = 4x - 3
From line equation y = mx + b
Therefore, the slope is 4
Since the are parallel line, they will have same slope
Finding the derivative of y = 2 + 2e^x − 4x
y = 2 + 2e^x − 4x
y' = 0 + 2e^x - 4
Therefore,
4 = 2e^x - 4
4 = e^x
x = ln 4 = 1.39
To find the y coordinate
y = 2 + 2e^x − 4x
y = 2 + 2e^ln 4 − 4 ln 4
y = 4.45
Hence, they are parallel at point (1.39 and 4.45)
Answer:
−
311.44
Step-by-step explanation:
I'm not sure about my answer but i tried
To solve for y, apply the distributive property:
Then, subtract 12 from both sides and you will get:
Then solve for y, by dividing both sides by 10.
Your final answer will be y=1.2
