Answer:
45.6°
Step-by-step explanation:
The attached result was found by typing "arccos(7/10) in degrees" into a web browser search box.
Your calculator can give you the same result. The inverse cosine function often shares a key with the cosine function. It is often marked as cos⁻¹. Be sure that the angle mode is set to degrees, not radians.

The income of a computer analyst varies directly as the number of hours worked. If the analyst earned $256 for working 8 hours, what is the constant variation?
Answers
Answer:
$32 per hour
Step-by-step explanation:
if a person makes $256 per 8 hours then we can divide 256 by 8 so that we get the unit of dollars per hour.
$256/8 hour= $32 per hour
you can write this as k=y/x
which can also be 32=256/8

A sample of 100 women is obtained, and their heights (in inches) and pulse rates (in beats per minute) are measured. The linear correlation coefficient is 0.239 and the equation of the regression line is y = 18.5 + 0.890x, where x represents height. The mean of the 100 heights is 62.9 in and the mean of the 100 pulse rates is 73.4 beats per minute. Find the best predicted pulse rate of a woman who is 65 in tall. Use a significance level of α=0.01 The best predicted pulse rate of a woman who is 65 in tall is_______beats per minute.. (Round to two decimal places as needed.) Answer
Answers
Answer:
54.07 inches
Step-by-step explanation:
Given the regression equation :
y = 18.5 + 0.890x
y = pulse rate in beats per minute
x = height
The best predicted pulse rate of a woman who is 65 inches
Put y = 65 in the regression equation :
65 = 18.5 + 0.890x
65 - 18.5 = 0.890x
46.5 = 0.890x
Divide both sides by 0.890
46.5 / 0.890 = 0.890x / 0.890
54.0697 = x
The best predicted pulse rate for a woman wo is 65 inches tall is 54.07 inches

What happens to the volume of a sphere if its radius is multiplied by 6?
Answers
Answer:
216 times the original
Step-by-step explanation:
Volume 1 = 4/3 πr³
volume 2 = 4/3 π(6r)³
v 2 / v 1 = 6³ = 216
When the radius of a sphere is multiplied by 6, the volume is multiplied by 216
How to determine the volume?Let the radius of the sphere be r
The volume of a sphere of radius, r is calculated as:
v = 4/3 πr³
When multiplied by 6, the radius becomes:
R = 6r
The new volume is then calculated as:
V = 4/3 π(6r)³
Divide both volumes
V/v = 4/3 π(6r)³ / 4/3 πr³
Evaluate the quotient
V/v = 6³
V/v = 216
Hence, when the radius of a sphere is multiplied by 6, the volume is multiplied by 216

What was the total distance, in miles, Eil has biked when he finally reached the library?
Answers
Answer:
Distance covered by Eli is [tex]5\frac{19}{20}[/tex] miles.
Step-by-step explanation:
Eli biked the distance from his home initially = [tex]1\frac{1}{10}[/tex] miles
Then he remembered that he had left a book at home.
He came back home and traveled the distance = [tex]1\frac{1}{10}[/tex] miles
Then he reached the library by traveling the distance = [tex]3\frac{3}{4}[/tex] miles
Total distance covered by him = [tex]1\frac{1}{10}+1\frac{1}{10}+3\frac{3}{4}[/tex]
= [tex]1 + \frac{1}{10}+1+\frac{1}{10}+3+\frac{3}{4}[/tex]
= 5 + [tex]\frac{1}{10}+\frac{1}{10}+\frac{3}{4}[/tex]
= [tex]5+\frac{2}{20}+\frac{2}{20}+\frac{15}{20}[/tex]
= [tex]5+\frac{19}{20}[/tex]
= [tex]5\frac{19}{20}[/tex] miles
Therefore, distance covered by Eli is [tex]5\frac{19}{20}[/tex] miles.

Answer:
D: (-∞,2) (2,∞)
R:(-∞,0),(0,∞)
Step-by-step explanation:
From the graph we can see that the graph is approaching 0 horizontally and 2 vertically but not crossing so we can assumer these are the asymptotes. So the domain goes all the way from -∞ to 2 but does not cross 2 so we have to stop there and create another bracket for 2 to ∞. It is the same process for the range but in the y direction.
