In 2016, there were approximately 4.46 x 10° people in Asia. On average, a person takes 8.4 x 106 breaths
serious [3.7K]

Answer:

3.75 x 10^7

a = 3.745 (rounded) or 3.7464 (exact)

b = 7

Step-by-step explanation:

Assuming you meant "a person takes 8.4 x 10^6 breaths

per year" we would multiply the number of people 4.46 x 10° by the number of breaths each person takes 8.4 x 10^6 and we get 37464000 and in scientific notation it would be 3.75 x 10^7

Classify the model as Exponential GROWTH or DECAY. <br> A=10(1.01)^3
Masteriza [31]

Answer:

GROWTH

Step-by-step explanation:

Given the Exponential function;

A=10*1.01^{3}

As we can see in the given function above:

the base number is 1.01 which is greater than 1 hence the quantity increases,

slowly at first and then very rapidly over its domain. The rate of growth becomes faster as time passes.

The growth "rate" (r) is determined as b = 1 + r.

In this situation, the rate growth is = 1.01 -1  = 0.01

Hope it will find you well.

Help please!!! <br> Thank you
konstantin123 [22]

Answer:

136

Step-by-step explanation:

Formula for area of a trapezoid = A=\frac{a+b}{2} h

where a and b = bases and h = height

The trapezoid has the following dimensions

Base 1 = 12 cm

base 2 = 22 cm

Height = 8 cm

Using these dimension, we plug in the values into the formula

A=\frac{12+22}{2} 8\\12 +22=34\\\frac{34}{2} =17\\17*8=136\\A=136

Hence, the area of the trapezoid is 136cm²
