sin(6.5)=7,000/x
solve for x
x=7,000/sin(6.5)
using a calculator
x=61,835.70 ft
Convert to miles
Remember that
1 mile=5,280 ft

Challenge A family wants to rent a car to go on vacation. Company A charges $75.50 and14¢ per mile. Company B charges $30.50 and 9¢ per mile. How much more does Company Acharge for x miles than Company B?For x miles, Company A charges dollars more than Company B.(Simplify your answer. Use integers or decimals for any numbers in the expression.)
Answers
Company A charges $75.50 and 14¢ per mile, then for x miles, Company A charges 75.5 + 0.14x dollars
Company B charges $30.50 and 9¢ per mile, then for x miles, Company B charges 30.5 + 0.09x dollars
Subtracting the second equation to the first one,

How many degrees was ABCDE rotated? (submit your answer as a number)
Answers
If a figure has a vertex, (x, y) and it is rotated 180 degrees counterclockwise, the corresponding vertex of the new image would have a coordinate of (- x, - y)
Looking at the given figure, we would compare the corresponding coordinates of a given vertex. Looking at vertex A,
For the original figure, the coordinate is (1, 3)
For the ratated figure, the coordinate of A' is (- 1, - 3)
This corresponds to what was we stated earlier
Thus, it was rotated 180 degrees in the counterclockwise direction

ANSWER
[tex]\begin{equation*} -3,1 \end{equation*}[/tex]EXPLANATION
The graphical solution to the given equation is obtained at the points where the two graphs of the two functions intersect each other on the coordinate plane.
To graph f(x), we simply draw a straight horizontal line at the point y = -5.
To graph g(x), we have to find coordinate points by substituting values of x into the function and obtaining values for g(x).
Let us find the value of g(x) when x = -3, -1, 1:
[tex]\begin{gathered} x=-3: \\ g(-3)=(-3)^2+2(-3)-8=9-6-8 \\ g(-3)=-5 \\ x=-1: \\ g(-1)=(-1)^2+2(-1)-8=1-2-8 \\ g(-1)=-9 \\ x=1: \\ g(1)=(1)^2+2(1)-8=1+2-8 \\ g(1)=-5 \end{gathered}[/tex]Now, we have three points to plot the graph with: (-3, -5), (-1, -9), (1, -5)

b. Solve the system of linear equations y = x + 2 and y = 3x – 4 by graphing.
Answers
To find the solution we need to graph both lines on the plane. To do this we need to find two points for each line.
First we graph the line y=x+2. To find a point we give x a value, whichever value we like, and then find y.
Let x=0, then:
[tex]\begin{gathered} y=0+2 \\ y=2 \end{gathered}[/tex]Then we have the point (0,2).
Let x=1, then:
[tex]\begin{gathered} y=1+2 \\ y=3 \end{gathered}[/tex]Then we have the point (1,3).
Then we plot this points in the plane and join them with a line:
Now let's plot eh second line, y=3x-4.
Let x=0, then:
[tex]\begin{gathered} y=3(0)-4 \\ y=-4 \end{gathered}[/tex]So we have the points (0,-4).
Let x=1, then:
[tex]\begin{gathered} y=3(1)-4 \\ y=3-4 \\ y=-1 \end{gathered}[/tex]so we have the point (1,-1).
Now we plot this points and join them with a line:
Once we have both lines graph in the plane the solution is the intersection of the lines. Looking at the graph we conclude that the solution of the system is x=3 and y=5.

Answer:
• (a)X ~ N(16, 5)
,• (b)0.4207

Explanation:
(a)
• The mean amount of time = 16 days
,• The standard deviation = 5 days.
Therefore, the distribution of X is:
[tex]X\sim N(16,5)[/tex](b)P(X>17)
To find the required probabability, recall the z-score formula:
[tex]z=\frac{X-\mu}{\sigma}[/tex]When X=17
[tex]z=\frac{17-16}{5}=\frac{1}{5}=0.2[/tex]Next, find the probability, P(x>0.2) from the z-score table:
[tex]P(x>0.2)=0.4207[/tex]The probability that a randomly selected person with a kidney stone will take longer than 17 days to pass it is 0.4207.
(c)The upper quarter is the value under which 75% of data points are found.
The z-score associated with the 75th percentile = 0.674.
We want to find the value of X when z=0.674.
[tex]\begin{gathered} z=\frac{X-\mu}{\sigma} \\ 0.674=\frac{X-16}{5} \\ \text{ Cross multiply} \\ X-16=5\times0.674 \\ X=16+(5\times0.674) \\ X=19.37 \end{gathered}[/tex]The minimum number for the upper quarter of the time to pass a kidney stone is 19.37 days.

I need help with homework . BC=5, angle A=25 degree.
Answers
AC = 2.332
AB = 5.517
Explanation:
Given:
BC = 5.
Angle B = 25 degree.
Angle C = 90 degree.
The objective is to find AC and AB.
By the trigonometric functions, Consider AB as hypotenuse, AC as opposite and BC as adjacent.
Then, the relationship between opposite (AC) and adjacent (BC) cnbe calculated by trigonometric ratio of tan theta.
[tex]\begin{gathered} \tan \theta=\frac{opposite}{adjacent} \\ \tan 25^0=\frac{AC}{5} \\ AC=\tan 25^0\cdot5 \\ AC=2.332 \end{gathered}[/tex]Now, the length AB can be calculated by Pythagorean theorem,
[tex]\begin{gathered} AB^2=AC^2+BC^2 \\ AB^2=2.332^2+5^2 \\ AB^2=5.436+25 \\ AB^2=30.436 \\ AB=\sqrt[]{30.436} \\ AB=5.517 \end{gathered}[/tex]Let's check the value using trigonometric ratios.
For the relationship of opposite and hypotenuse use sin theta.
[tex]\begin{gathered} \sin \theta=\frac{opposite}{hypotenuse} \\ \sin 25^0=\frac{2.332}{y} \\ y=\frac{2.332}{\sin 25^0} \\ y=5.517 \end{gathered}[/tex]Thus both the answers are matched.
Hence, the length of the side AC = 2.332 and the length of the side AB = 5.517.

Also, let's find the width in centimeters:
[tex]\frac{45}{30}=1.5\operatorname{cm}[/tex]Thus, we have:
Length of scale drawing = 3 cm
Width of scale = 1.5 cm
To find the Area of the scale drawing, use the area of a rectangle:
A = Length x Width
[tex]A=3\times1.5=4.5\operatorname{cm}^2[/tex]Therefore, the length of the scale drwing is = 4.5 cm²
ANSWER:
[tex]4.5\operatorname{cm}^2[/tex]translate the following into an equation:6 less decreased by twice a number results in 8
Answers
Let the number be x.
Twice the number means 2 * x = 2x
Twice the number decreased by 6 means
2x - 6
Given that the result is 8, we have
2x - 6 = 8
