Step-by-step explanation:

P(t) = 12,000 (2)^(-t/15)

9,000 = 12,000 (2)^(-t/15)

0.75 = 2^(-t/15)

ln(0.75) = ln(2^(-t/15))

ln(0.75) = (-t/15) ln(2)

-15 ln(0.75) / ln(2) = t

t = 6.23

Tell whether each scale reduces enlarges or preserves the size of an actual object

mr_godi [17]

Given:

1 m : 25 cm

8 in : 1 ft

12 in : 1 ft

First, we convert each variable given on the right:

1 m : 0.25 m (this means that 1 meter is made to represent 25 cm)

8 in : 12 feet (this means that 8 in is made to represent 1 feet)

12 in : 12 in (this means that 12 in is made to represent 1 feet)

After converting the variables, we can now know if the ratios are enlargement, reduction or preservation. Therefore:

1 m : 25 cm = Enlarge

8 in : 12 feet = Reduce
12 in = 1 ft = Preserve

Answer:

Angle

Step-by-step explanation:

Since, the figure is in the final step of construction. So, it will have only two rays which as we can see are emerging from a common point.

So, it represents an angle.

An angle has two rays arising out of a common vertex point.
