Consider the function f ( x ) = cos ( 0.65 x ) f(x)=cos(0.65x). How much does x x have to vary for the argument of f f to vary by 2 π 2π?
We want to see how much must vary x so the argument of f(x) varies by 2 pi. We will see that x must vary (2π)/0.65.
So let's take the variation from 0 to 2π.
The argument is zero when x = 0
Argument = 0.65*x
if x = 0
Argument = 0.65*0 = 0
Now let's see which must be the value of x such that the argument is equal to 2π, so we must solve:
2π = 0.65*x
(2π)/0.65 = x
So we can see that x must vary from 0 to (2π)/0.65, or just a variation of (2π)/0.65.

The radius of the earth is approximately 6400 km. The equator is the circle around the earth dividing it into the northern and southern hemisphere. (The center of the earth is also the center of the equator.) What is the length of the equator?
Use 3.14 for .Round your answer to the nearest ten thousand.
Answer:
Length of equator = 40212.39 km
Step-by-step explanation:
Hope this helps! Please mark brainliest for you can! :)
Answer:
40,000 km
Step-by-step explanation:
The circumference is given by the formula ...
C = 2πr
For the given values of π and radius, the circumference is ...
C = 2·3.14·6400 km = 40,192 km
Rounded to the nearest 10,000, the length of the equator is 40,000 km.

Additional comment
The original definition of the meter was 1/10,000,000 of the distance from the north pole to the equator, through Paris. Essentially, the polar circumference of the earth was defined as about 40,000 km. The polar distance in the southern hemisphere will differ from that in the northern hemisphere, and apparently, the chosen longitude also makes a difference. All of these are different from the equatorial circumference. That definition has long been superseded.

whats the greatest common factor of 18 and 27 and 54
Answer: 9
Step-by-step explanation:
From doing the math I think it should be 9
Start with the smallest number, 18:
The factors of 18 are: 1, 2, 3, 6, 9, 18.
So the GCF for all three must be one of those.
Now consider the next smallest number. Of the factors of 18, only these are also factors of 27:
1, 3, 9
Now consider the last number, 54. Of the remaining factors, 9 is the greatest and 9 goes into 54.
The GCF is 9.
By starting with the smallest number, you usually limit how many factors you'll ever need to consider.

Answer:
226
Step-by-step explanation:
In the given picture,
Trapezoid PQRS has two points T and U as the midpoints of sides PS and RQ.
Segment TU joins the midpoints of the sides PS and RQ.
Mid-segment theorem states that "If a line joining midpoints of a trapezoid is parallel to the bases, length of this segment is half the sum of lengths of the bases."
Therefore, m(TU) =
7x - 26 =
7x - 26 = 6x + 10
7x - 6x = 26 + 10
x = 36
m(TU) = 7x - 26
= 7(36) - 26
= 252 - 26
= 226
Therefore, Option (1) will be the answer.

if the first equation is -5x+21=18y, then:
[tex]\left \{ {{y=2x+8} \atop {-5x+21=18*(2x+8)}} \right. \ => \ \left \{ {{y=2x+8} \atop {-5x+21=36x+144}} \right. \ => \ \left \{ {{y=2x+8} \atop {41x=-123}} \right. \ => \ \left \{ {{y=2} \atop {x=-3}} \right.[/tex]
The finishing times for a race happen to be normally distributed with a mean of 10.2 seconds and a standard deviation of 1.4 seconds. Find the cut off score for the top 10%. Interpret this result.
Using the normal distribution, it is found that the cut off score for the top 10% is of 8.4 seconds. It means that a person with a time of 8.4 seconds or lower is in the faster 10% of runners.
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem:
Mean of 10.2 seconds, hence [tex]\mu = 10.2[/tex]Standard deviation of 1.4 seconds, hence [tex]\sigma = 1.4[/tex].The lower the times, the faster the runners are, hence, the cut off score for the top 10% is the 10th percentile, which is X when Z has a p-value of 0.1, so X when Z = -1.28.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1.28 = \frac{X - 10.2}{1.4}[/tex]
[tex]X - 10.2 = -1.28(1.4)[/tex]
[tex]X = 8.4[/tex]
The cut off score for the top 10% is of 8.4 seconds. It means that a person with a time of 8.4 seconds or lower is in the faster 10% of runners.

Evaluate the expression when x = 1/4 and y = 1/2
2 (1/16 + x2) + 5y
Answer:
2 3/4
Step-by-step explanation:
x = 1/4
y = 1/2
so we have to plug in these numbers wherever we see x and y
2 (1/16 + (1/4)^2) + 5(1/2)
using pemdas we solve what's in the parenthesis first
(1/16 + (1/4)^2) = (1/8)
next is multiplication so
2 (1/8) = 1/4 and 5(1/2) = 5/2
lastly we add so
1/4 + 5/2 = 11/4 or 2 3/4
