A horse that is ill needs medication. The medication costs the veterinarian $17.50 to buy. He marked up the medication 54.2% before selling it to the customer. Find the final selling price of the horse’s medication.
Answer:
$26.99
Step-by-step explanation:
17.50 original cost plus a 54.2% increase
First, divide percentage by 100 to get a decimal to divide by 54.2/100=0.542
Then multiply the new decimal by the original cost to find the amount marked up. 17.50 x 0.542= 9.485
Now add 9.485 to the original cost
17.50+9.485=26.985-> 26.99 rounded for the final answer

The following table shows the distance from the bus stop as a function of time:
Time (in minutes) Distance (in meters)
(x) f(x)
0 45
3 40
6 35
9 30
12 25
Find and interpret the meaning of the x-intercept in this scenario. (4 points)
(45, 0); the distance away from the bus stop
(27, 0); the time it takes to reach the bus stop
(45, 0); the time it takes to reach the bus stop
(27, 0); the distance away from the bus stop
The x-intercept is (27,0). The time it takes to reach the bus stop
We first find the equation between time and distance as a linear function by finding the slope and y-intercept from the table values.
If we write the Time as x-values and Distance as y-values, we get the points,
(0,45), (3,40), (6,35), (9,30), (12,25)
We can find the slope from these points considering two points (0,45) and (3,40)
Slope = 45-40/0-3 = -5/3
The y-intercept of the function is the value of f(x) at x = 0.
Here, from the table, when x = 0, y = 45.
So y-intercept = 45
Then the equation of distance in terms of time is,
y = -(5/3)x+45
The x-intercept is the x-value when y = 0.
So when y = 0,
0 = -(5/3)x+45
⇒ (5/3)x=45
⇒ x = 45x 3/5
⇒ x = 27
Therefore, x-intercept = (27,0).
It is the time (in minutes) when distance = 0 meters.
So x-intercept is the time it takes to reach the bus stop.

The vertices of triangle SRQ have coordinates S (1, 1), R (3, 4), and Q (7, 0). If triangle SRQ is rotated about the origin 180°, what are the resulting coordinates of the point R?
Answer:
Step-by-step explanation:
its 3 4
R' (-3,-4) are the resulting coordinates of the purpose R.
A rotation may be a transformation in a plane that turns every point of a preimage through a specified angle and direction about a fixed point. The fixed point is named the center of rotation . The quantity of rotation is called the angle of rotation and it is measured in degrees. Use a protractor to live the specified angle counterclockwise.
Using the rule for a 180° rotation to seek out the vertices of the rotated triangle.
T: (x, y) ⇒ (-x, -y)
Given points of triangle: S(1,1) , R (3, 4) and Q (7, 0).
Rotation 180° about the origin.
S (1, 1) → S' (-1,-1)
R (3,4) → R' (-3,-4)
Q (7,0) → Q' (-7,0)
Hence, the coordinate of the R is: R' (-3,-4).

Write an equation in slope-intercept form of the line that passes through the given point and is parallel to the graph of the given equation. (-8, -5); y= -3x + 5
Step-by-step explanation:
a parallel line must have the same slope (otherwise it cannot be parallel).
a slope-intercept form looks like
y = ax + b
"a" (the factor of x) is always the slope, "b" is the y-intercept (the y-value when x = 0).
so, we know from y = -3x + 5 that the slope of the new line is also -3.
to get b we use the coordinates of the given point :
-5 = -3×-8 + b = 24 + b
-29 = b
that means the line equation is
y = -3x - 29

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.
A triangle ABC is shown. The base of the triangle extends into a straight line. The angle formed between this straight line and the edge of the triangle is marked as p. The angle adjacent to p is marked as o, and the other two angles inside the triangle are marked as m and n.
Step 1: m∠m + m∠n + m∠o = 180 degrees (sum of angles of a triangle)
Step 2: m∠p + m∠o = 180 degrees (adjacent supplementary angles)
Step 3: Therefore, m∠m + m∠n + m∠o = m∠n + m∠p
Step 4: So, m∠m + m∠n = m∠p
In which step did the student first make a mistake and how can it be corrected? (4 points)
Step 2; it should be m∠o − m∠p = 90 degrees (complementary angles)
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (corresponding angles)
Step 3; it should be m∠m + m∠n + m∠o = m∠o + m∠p
Answer:
Step 3; it should be angle m + angle n + angle o = angle o + angle p
Step-by-step explanation:
yes, the sum of the inner angles of the triangle, m, n, o must be 180°.
yes, the sum of supplementary angles (which the pair of inner and outer angles always is) p and o must be 180°.
so, step 3 wants to show that the sum of the 3 inner angles is the same as the sum of the inner/outer angle pair. m + n + o = o + p = 180.
but instead of o the student suddenly wrote n in the right side of the equation. and that is wrong. n + p can't be 180°, as both are inner angles, and that would make the third inner angle 0°, which is not really possible.
so, once n is replaced by o on the right side of the equating in step 3, all is correct again.
and step 4 is correct anyway (it fixed the mistake in step 3 of the original proof by another mistake, coming to the right conclusion just by coincidence), now that step 3 is corrected.

The inches that are expected more in September than in February is 3.94
What is average and how to calculate it?
Average is ratio of the sum of all elements of dataset and total number of elements in the dataset. To calculate first find the sum of all elements of the dataset and then divide it by total number of elements in the dataset
The average rainfall for key west is 1.52 inches in February and 5.45 inches in month of September

Write the equation of the line that goes between the two points (6, -5) and (2, 3).
The equation of the line that passes through points (6, -5) and (2, 3) is y = -2x + 7.
How to determine the equation of line from two points?The formula for equation of line is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
Given the data in the question;
Point 1 ( 6, -5 )
x₁ = 6y₁ = -5Point 2 ( 2,3 )
x₂ = 2y₂ = 3First, we determine the slope of the line.
Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope m = ( 3 - (-5) ) / ( 2 - 6 )
Slope m = ( 3 + 5 ) / ( 2 - 6 )
Slope m = ( 8 ) / ( -4 )
Slope m = -2
Now that the value of slope is known, we determine the y-intercept 'b' by plugging the slope and one point into equation of line formula.
y = mx + b
-5 = (-2)(6) + b
-5 = -12 + b
b = -5 + 12
b = 7
Now that the values of slope m and y-intercept b is known, plug these into y = mx + b to determine the equation of the line.
y = mx + b
y = (-2)x + 7
y = -2x + 7
Therefore, the equation of the line is y = -2x + 7.

If the bottom of the ladder slides away from the wall, then x changes by 12cosθ with respect to theta and when θ = π/6, x changes by 6[tex]\sqrt{3}[/tex] inches with respect to θ.
Here, we are given that a ladder 16 ft long rests against a vertical wall and theta is the angle between the top of the ladder and the wall.
We know that, sin of an angle = opposite / hypotenuse
Thus, sinθ = x/16
⇒ x = 16 sinθ
The rate of change of x with respect to θ will be given by dx/dθ
dx/dθ = d/dθ (12sinθ)
= 12 d/dθ (sinθ)
= 12cosθ
Now, we need to find the value of dx/dθ when θ = π/6,
= 12 cosπ/6
= 12 ([tex]\sqrt{3}[/tex]/2)
= 6[tex]\sqrt{3}[/tex]
Thus, when θ = π/6, x changes by 6[tex]\sqrt{3}[/tex] inches with respect to θ.
