The cities are 12.2 miles apart
<u>Step-by-step explanation:</u>
The scale of the map is,
5cm = 10 miles
The distance between the 2 cities in map is 6.2 cm
The actual distance between the 2 cities = (6.2 x 10) / 5
= 62/5
= 12.4
The 2 cities are 12.4 miles apart.
Answer:
<em>M(13)=14.3 gram</em>
Step-by-step explanation:
<u>Exponential Decay Function</u>
The exponential function is used to model natural decaying processes, where the change is proportional to the actual quantity.
An exponential decaying function is expressed as:

Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
The element has an initial mass of Mo=970 grams, the decaying rate is r=27.7% = 0.277 per minute.
The equation of the model is:


Operating:

After t=13 minutes the remaining mass is:

Calculating:
M(13)=14.3 gram
Answer:
Step-by-step explanation:
1. Perimeter: 8cm + 8cm + 3cm + 3cm = 22cm
Area: 8cm x 3cm = 24cm
2. Perimeter: 5m + 5m + 5m + 5m = 20m
Area: 5m x 5m = 25m
3. Perimeter: 4m + 4m + 18m + 18m = 44m
Area: 4m x 18m = 72m
The opposite number closest to negative five is positive 5
