Answer:
504 miles
Step-by-step explanation:
you would do 756÷12 which equals 63.... For every hour that you drive its 63 miles. Then you do 63×8 to get 504
Given: y = 100 - 2x
New: y = 100 - 2(x + 3)
= 100 - 2x - 6
= 94 - 2x
The original equation had a y-intercept of 100. The new equation has a y-intercept of 94. The y-value changes -6 units
Answer: -6
Answer:
that it should be the last alined coordinates.
Step-by-step explanation:
Answer:
The rate at which both of them are moving apart is 4.9761 ft/sec.
Step-by-step explanation:
Given:
Rate at which the woman is walking, = 3 ft/sec
Rate at which the man is walking, = 2 ft/sec
Collective rate of both, = 5 ft/sec
Woman starts walking after 5 mins so we have to consider total time traveled by man as (5+15) min = 20 min
Now,
Distance traveled by man and woman are and ft respectively.
⇒
⇒
As we see in the diagram (attachment) that it forms a right angled triangle and we have to calculate .
Lets calculate h.
Applying Pythagoras formula.
⇒
⇒
Now differentiating the Pythagoras formula we can calculate the rate at which both of them are moving apart.
Differentiating with respect to time.
⇒
⇒
⇒ ...as
⇒ Plugging the values.
⇒ ...as ft/sec
⇒ ft/sec
So the rate from which man and woman moving apart is 4.9761 ft/sec.
I say it could surely be d not sure
