(45, 0); the time it takes to reach the bus stop

Answers
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.

Kamryn’s doctor recommended that she drink 64 fluid ounces of water every day. There are about 30 milliliters in 1 fluid ounce. Which measurement represents the number of milliliters in 64 fluid ounces?
help my teacher wants the answer in 15 minutes please help!!!
Answers
The 64 fluid ounces of water, as suggested by Kamryn's doctor to drink everyday, will be equal to 1920 millilitres.
Writing the equation as per the relation between millilitres and fluid ounces -
1 fluid ounce = 30 millilitres
Now, we will perform multiplication to find the number of milliliters in 64 fluid ounces. Writing the expression representing relation between millilitres and fluid ounces
Number of milliliters = 30×64
Performing multiplication between the numbers 30 and 64
Number of milliliters = 1920
Therefore, on drinking 64 fluid ounces by Kamryn on her doctor's recommendation will drink 1920 millilitres of water everyday.

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
Answers
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
Answers
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.

Write the equation of the line that goes between the two points (6, -5) and (2, 3).
Answers
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.

Answers
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.

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.
Answers
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
