The nearest whole number the diameter of the circle is 5.0 cm.

<u>Given the following data:</u>

  • Circumference of a circle = 15.4 cm

To estimate to the nearest whole number the diameter of the circle:

In this exercise, you're required to solve for the diameter of a circle and round up its value to the nearest whole number.

<h3>How to calculate the circumference of a circle.</h3>

Mathematically, the circumference of a circle is given by the formula:

Circumference = \pi D

<u>Where:</u>

  • D is the diameter of a circle.

Making D the subject of formula, we have:

D =\frac{circumference}{\pi}

Substituting the given parameters into the formula, we have;

D =\frac{15.4}{3.142}

D = 4.90 cm

To the nearest whole number:

D = 4.90 ≈ 5.0 cm

Which polygon has an interior angle sum of 1080°?
Rus_ich [418]

Step-by-step explanation:

  • The sum of the interior angles in a regular polygon is given by the formula 180(n – 2), where n is the number of sides in the polygon. An octagon has eight sides, so the sum of the angles of the octagon is 180(8 – 2) = 180(6) = 1080 degrees. Because the octagon is regular, all of its sides and angles are congruent.

What is the rate of growth as a percent for the following function d(x)=23(1.0032)^x
spayn [35]

Answer:

g(x), the % growth rate function, is g(x)=(1.0032^{b-a}-1)*100\ percent

where b and a are x-values of the function d(x), b > a, and a ≠ 0.

Step-by-step explanation:

So,

Since no two values were specified, I will proceed to make a new function, the % growth rate function g(x), based on the one you have given.

We can define g(x) as follows:

g(x)=\frac{d(b)-d(a)}{d(a)}*100\ percent

Where b and a are x-values, b > a, and a ≠ 0.

Substituting the function for values a and b, we get:

g(x)=\frac{23(1.0032)^b-23(1.0032)^a}{23(1.0032)^a}*100\ percent

Simplifying, we get:

g(x)=\frac{1.0032^b-1.0032^a}{1.0032^a}*100\ percent\\ or\\ g(x)=(1.0032^{b-a}-1.0032^{a-a})*100\ percent

g(x)=(1.0032^{b-a}-1)*100\ percent

<span>P(x) = –x4 + x3 + 7x2 − x − 6

The graph will look like a bell, or a downward facing parabola, since the dominant term is -x^4

The graph has a y-intercept of -6, which can be considered the fixed cost (cost of zero trees cut) and moves upward from there, eventually reaching a maximum at some positive number of trees and dropping again. As x gets very large, profit becomes a very large negative number. Since we can't have negative trees cut, we're only interested in positive x values

The company breaks even at P(x) = 0
0 = </span> –x4 + x3 + 7x2 − x − 6, x greater than zero
0 = (x+2)(x+1)(x-1)(x-3)
The company breaks even at 1 tree and 3 trees.
