Answer:
Step-by-step explanation:
Mass m=25 g
Volume V=1.29 cm³
density D=M/V
=25/1.29
≈19.38
≈19 g/cm³
For this case we have an exponential expression of the form:

We can rewrite the exponential expression using power properties.
We have then:

From here, we take the square root of 36.
We have then:
Answer:
The exponential function is given by:
Answer:
85,1 ft^2
Step-by-step explanation:
Semicircle area : 4^2π / 2 = 8π = 25,1 ft^2
Triangle area : (8 x 15) / 2 = 60 ft^2
Total Area = 60 + 25,1 = 85,1 ft^2
Since there are 100 squares and 6 aren’t colored in, the answer should be .94. It’s kind of like counting a dollar since 100 pennies = a dollar.
