The correct answer to this question is A. 9.4 x 10^{-8}, 9.25 x 10^{-6}, 2.5 x 10^{3}, 7 x

Explanation:

These numbers are written in scientific notation. In this system, the exponent shows the number of spaces the period has been moved to make the number shorter. Additionally, a positive exponent shows the number has a certain number of digits to the right, while a negative exponent shows the number has digits to the left. In this way, the numbers presented can be converted as:

9.4 x 10^{-8} = 0.000000094 (Exponent indicates eight spaces to the left)

9.25 x 10^{-6} = 0.00000925 (Exponent indicates six spaces to the left)

2.5 x 10^{3} = 2500 (Exponent indicates three spaces to the right)

7 x 10^{3} =  7000 (Exponent indicates three spaces to the right)

Which expression shows the area of the base of each pyramid? (One-fourth x) squared in.2 (One-third x) squared in.2 (One-half x)
777dan777 [17]

Answer:

(a) Area = (\frac{x}{4})^2

Step-by-step explanation:

The question is incomplete. (See comment for complete question).

From the completed question, we have:

Total\ base\ length = x

n = 8 --- number of pyramids

Required

An expression for the area of the base

The total base length of the pyramid represents the perimeter of the base.

And since the base is a square, then the following relationship exist.

Total\ base\ length = 4L

Where L represents the length of each side.

This gives

4L = x

Make L the subject

L = \frac{x}{4}

The area of the base is then calculated as:

Area = L^2

Area = (\frac{x}{4})^2

A type of plant is introduced into an ecosystem and quickly begins to take over. A scientist counts the number of plants after m
Artyom0805 [142]

With no limiting factors to the growth of the plants, the number of  months have passed since the plants were first introduced is 23.1.

<h3>What is an exponential function?</h3>

Exponential function is the function in which the function growth or decay with the power of the independent variable. The curve of the exponential function depends on the value of its variable.

A type of plant is introduced into an ecosystem and quickly begins to take over.

A scientist counts the number of plants after m months and develops the equation to model the situation, which is given as,

p(m)=19.3(1089)^m

Most recently, the scientist counted 138 plants.

138=19.3(1089)^m\\(1089)^m=7.15

Taking log both sides of the equation,

\log(1.089)^m=\log7.15\\m\log(1.089)=\log(7.15)\\m=\dfrac{\log7.15}{\log(1.089)}\\m\approx23.1

Thus, with no limiting factors to the growth of the plants, the number of  months have passed since the plants were first introduced is 23.1.
