Answer:
<h2><em>
1.75ft/s²</em></h2>
Step-by-step explanation:
The total change in elevation of the skier is its acceleration. Acceleration is the change in velocity of a body with respect to time.
Acceleration = Velocity/Time
Given velocity of the skier = 14feet/sec
Time taken = 8secs
Acceleration of the skier = 14/8
Acceleration of the skier = 1.75ft/s²
<em>Hence the total change in elevation after 8 seconds is 1.75ft/s²</em>
Answer:
- The population in 2001 is 23.1 million
- It will reach 28.3 million in 2013
Step-by-step explanation:
Given
Solving (a): Population in 2000.
This implies that
So, we have:
Solve the exponent
The population in 2001 is 23.1 million
Solving (b): When will it reach 28.3 million
This implies that:
So, we have:
Divide both sides by 23.1
Take natural logarithm of both sides
Rewrite as:
So:
Make t the subject
Add the value of t to 2013 to get the actual year
It will reach 28.3 million in 2013
Answer:
The answer is -6.
Step-by-step explanation:
You have to substitute x = -4 into the expressions :
3x - x + 2
= 3(-4) - (-4) + 2
= -12 + 4 + 2
= -6
Answer:
Scale Factor=2
Step-by-step explanation:
As the rectangle is enlarging from GHIJ to KLMN
then
Sacle Factor = Larger length / Smaller Length
Scale Factor = 5 cm / 2 cm = 2
Scale Factor = 20 cm / 10 cm = 2
The answer is 7606 and 5/8
Hope it helped!
