Find the value of x. Round to the nearest whole number.
Use trigonometry.
sin x = opposite ÷ hypotenuse
sin x = 7/9
Take the arcsin on both sides.
arcsin(sin x) = arcsin(7/9)
x = 51.057558731
Rounding to the nearest whole number means to round to the ones place.
Answer: x = 51 degrees

If the correlation coefficient in an ordinary least squares regression = 1.00, then A. all the data points must fall exactly on a straight line with a positive slope. B. all the data points must fall exactly on a straight line with a slope that equals 1.00. C. all the data points must fall exactly on a horizontal straight line with a zero slope. D. all the data points must fall exactly on a straight line with a negative slope.
Answer: Option A is correct.
Step-by-step explanation:
The correlation coefficient(r) is a statistical measure that computes the strength of the relationship between two variables.It lies between -1 and 1.
If the correlation coefficient in an ordinary least squares regression = 1.00.
That indicates that there is a perfect relationship between the variables.
i.e. all the data points must fall exactly on a straight line with a positive slope. .
[when r is positive, the slope of the line is positive].
i.e. option A is correct.
All the data points must fall exactly on a straight line with a positive slope. Then the correct option is A.
What is the correlation coefficient?It is a statistical concept that helps in establishing a relation between the predicted and actual value obtained in a statistical experiment. It explains the exactness of the predicted value and actual value.
If the correlation coefficient in an ordinary least squares regression = 1.00.

Step-by-step explanation:
You park your car, and start walking west on Robinson Street at a speed of 2.1 m/s. After 16 minutes, you turn left. It really is a beautiful day out, and so you slow your speed to 1.1 m/s and continue walking to the south on Rosalind Avenue for another 12 minutes. At this point, you realize that you have a library book on hold at the downtown branch, and decide to make a quick detour to pick it up. You turn right and jog west at a speed of 3.4 m/s for 28 seconds to cross the street before the light changes. At this point, how far (in meters) are you from your car?
Answer:
The distance is 2077.77m
Step-by-step explanation:
Given
Represent speed with s and time with t
[tex](s_1, t_1) = (2.1m/s,16min)[/tex] ---- Left
[tex](s_2, t_2) = (1.1m/s,12min)[/tex] --- South
[tex](s_3, t_3) = (3.4m/s,28sec)[/tex] ---- Right
Required
How far are you from your car?
[tex]distance=speed * time[/tex]
To solve this question, I will use the attached image to illustrate the movement.
First, we calculate distance AB
Using: [tex](s_1, t_1) = (2.1m/s,16min)[/tex] ---- Left
[tex]d_1 = s_1 * t_1[/tex]
[tex]d_1 = 2.1m/s * 16min[/tex]
Convert min to secs
[tex]d_1 = 2.1m/s * 16*60s[/tex]
[tex]d_1 = 2016m[/tex]
[tex]AB = 2016m[/tex]
Next, we calculate the distance BC
Using: [tex](s_2, t_2) = (1.1m/s,12min)[/tex] --- South
[tex]d_2 = 1.1m/s * 12min[/tex]
[tex]d_2 = 1.1m/s * 12*60s[/tex]
[tex]d_2 = 792m[/tex]
[tex]BC = 792m[/tex]
Next, we calculate distance CD
Using: [tex](s_3, t_3) = (3.4m/s,28sec)[/tex] ---- Right
[tex]d_3 = 3.4m/s * 28s[/tex]
[tex]d_3 = 95.2m[/tex]
[tex]CD = 95.2m[/tex]
The distance between you and the car is represented as AD.
Considering triangle AOD, we have:
[tex]AD^2 = AO^2 + OD^2[/tex]
Where:
[tex]AO = AB - BO[/tex]
and
[tex]BO = CD[/tex]
So:
[tex]AO = AB - CD = 2016m - 95.2m[/tex]
[tex]AO = 1920.8m[/tex]
[tex]OD = BC[/tex]
[tex]OD = 792m[/tex]
The equation becomes:
[tex]AD^2 = AO^2 + OD^2[/tex]
[tex]AD^2 = 1920.9^2 + 792^2[/tex]
[tex]AD^2 = 4317120.81m^2[/tex]
[tex]AD= \sqrt{4317120.81m^2[/tex]
[tex]AD= 2077.76822817 m[/tex]
[tex]AD= 2077.77 m[/tex] --- approximated

Find a formula for the general term an of the sequence, assuming that the pattern of the first few terms continues. (Assume that n begins with 1.)
{1, 7, 13, 19, 25, . . . }
Answer:
the formula is a_n = 6n - 5
Step-by-step explanation:
The formula is
Given that
{1, 7, 13, 19, 25, . . . }
The difference between the numbers is
7 - 1 = 6
13 -7 = 6
19 - 13 = 6
a = 1
d = 6
Now the formula is
a_n = a + (n - 1)d
= 1 + (n - 1)6
= 1 + 6n - 6
= 6n - 5
So, the formula is a_n = 6n - 5

In a circle, a 315 sector has area 504piin2. What is the radius of the circle?
Answer:
Step-by-step explanation:
θ = 315°×π/180° = 1.75π radians
area of circle = (area of sector)2π/θ
= (504π)2π/θ
