Answer:
Step-by-step explanation:
<u>Given</u>
- Investment P = $16800
- Interest rate r = 5% = 0.05
- Final amount A = $18900
- Time t = ?
<u>Use the formula</u>
- A = P(1 + rt), where A - final amount, P - investment, r- interest rate, t- time
<u>Substitute the given numbers and solve for t:</u>
- 18900 = 16800( 1 + 0.05t)
- 1 + 0.05t = 18900/16800
- 1 + 0.05t = 1.125
- 0,05t = 0.125
- t = 0.125/0.05
- t = 2.5 years
I’m pretty sure the scale factor is 1/3 since it’s dilating. Cause 9/3=3 and 6/3= 2
The slope of a line is 
where 
is the difference and 
and 
are the values.
In this case, the difference in is 10 and the difference in is 0
And division where the denominator being 0 leads to the answer being Undefined or Infinity as the line is directly on the axis.
C. D(1/2) (W XY Z)
the dilation factor is 1/2 because the new shape is half the size
If the company used rectangular prisms it would take 40 boxes (2400/60) to hold 2,400 pencils which would cost $20 (40 times 0.50). If they used cylindrical containers, they would need 30 containers (2400/80) for a total of $22.50 (30*0.75).
To minimize the cost the company should go with rectangular prisms as they are the most cost effective.
