The answer is D. 1.601 * 10^9
bezimeni [28]2 years ago

Answer:

Step-by-step explanation:

We start by finding what is inside the parenthesis, following the rules of pemdas we do 10 to the 6th power first, which comes out to be 1000000, we substitute this in instead of 10 to 6.

so we now have:

800.5x(2x1000000 )

Than finishing the parenthesis we multiply by 2

800.5x 2000000

than all you do is convert 800.5 to a decimal and 2000000 to an exponent, your teacher should have given you a chart or step by step directions for this part.

Have a great day!

A scientist is studying the growth of a particular species of plant. He writes the following equation to show the height of the
Savatey [412]

Answer:

(A) The reasonable domain to plot the growth function is (0 ≤ <em>n</em> < 5).

(B) The <em>y-</em>intercept of the function is 10 cm. It represents the height of the plant at the beginning of the experiment.

(C) The slope of 0.21 implies that the plant is growing 0.21 cm every day.

Step-by-step explanation:

The equation representing the height of the plant is:

f (n)=10\cdot (1.02)^{n}

(A)

It is provided that at the end of the study the height of the plant was approximately 11.04 cm.

Compute the range of values of <em>n</em> as follows:

f (n)=10\cdot (1.02)^{n}\\11.04 = 10\cdot(1.02)^{n}\\1.104 = 1.02^{n}\\\ln (1.104) = \ln (1.02^{n})\\\ln (1.104) = n \ln (1.02)\\\\n = \frac{\ln (1.104)}{ \ln (1.02)}\\\\n = 4.99630409516\\n\approx 5

Thus, the reasonable domain to plot the growth function is (0 ≤ <em>n</em> < 5).

(B)

The <em>y</em>-intercept, in this case would represents the height of the plant when they began the experiment.

That is, the <em>y</em>-intercept of the function is the value of f (n) for <em>n</em> = 0.

Compute the value of f (<em>n</em> = 0) as follows:

f (0)=10\cdot (1.02)^{0}=10

Thus, the <em>y-</em>intercept of the function is 10 cm. It represents the height of the plant at the beginning of the experiment.

(C)

Compute the values of f (n = 1) and f (n = 5) as follows:

f (1)=10\cdot (1.02)^{1}=10.2\\\\f (5)=10\cdot (1.02)^{5}=11.0408\approx 11.04

Compute the average rate of change as follows:

\text{Average rate of change}=\frac{f(n_{2})-f(n_{1})}{n_{2}-n_{1}}

                                    =\frac{11.04-10.20}{5-1}\\\\=\frac{0.84}{4}\\\\=0.21

Thus, the average rate of change of the function f(n) from n = 1 to n = 5 is 0.21.

The average rate of change is known as the slope of the function. The slope represents how much the plant is growing every day.

Thus, the slope of 0.21 implies that the plant is growing 0.21 cm every day.
