Mathematics

Answer:

287/2π

Step-by-step explanation:

We know that the equation for the circumference is πd, so with πd=287, we can divide both sides by π to get d, the diameter, equal to 287/π. Then, we can divide both sides by 2 to get d/2, or the radius, equivalent to 287/2π

General Formulas and Concepts:

<u>Trigonometry</u>

  • [Right Triangles Only] cos∅ = adjacent over hypotenuse

Step-by-step explanation:

<u>Step 1: Define</u>

We are given a right triangle. We can use trig to find the ratio.

<u>Step 2: Identify</u>

<em>POV from angle S</em>

Adjacent = 8

Hypotenuse = 17

<u>Step 3: Write</u>

  1. Substitute [cosine]:                    cos(s) = 8/17

How do the gcf and the lcm help you when multiplying and adding or subracting fractions
kari74 [83]
<h3>Explanation:</h3>

GCF: the greatest common factor of numerator and denominator is a factor that can be removed to reduce the fraction.

  <em>Example</em>

The numerator and denominator of 6/8 have GCF of 2:

  6/8 = (2·3)/(2·4)

The fraction can be reduced by canceling those factors.

  (2·3)/(2·4) = (2/2)·(3/4) = 1·(3/4) = 3/4

___

LCM: the least common multiple of the denominators is suitable as a common denominator. Addition and subtraction are easily performed on the numerators when the denominator is common.

  <em>Example</em>

The fractions 2/3 and 1/5 can be added using a common denominator of LCM(3, 5) = 15.

  2/3 + 1/5 = 10/15 + 3/15 = (10+3)/15 = 13/15

Determine if the function f is an exponential function. If so, identify the base. If not, why not? f(x) = 2^2x
const2013 [10]
Answer: c) The base is 2.

Reason: It is an exponential function because the variable (2) depends on the x.

Solve 2(4x + 5) &gt; 7x + 20.
choli [55]
2(4x+5)>7x+20  perform indicated multiplication on left side

8x+10>7x+20  subtract 7x from both sides

x+10>20  subtract 10 from both sides

x>10

or in interval notation, x=(10, +oo)
