A. y=-2x+23
B. y=2x+11
C. y=-3x+26
D. y=2x-11
Answer:
B
Step-by-step explanation:
To write the equation of the line, use the slope formula to find the slope. Then substitute the slope and a point into the point slope form. Simplify using the distributive property to write in slope intercept form.
[tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{25 - 17}{7-3} = \frac{8}{4} = 2[/tex]

a baker makes cakes and sells them at county fairs his initial cost was $45 to reserve a booth and $25 traveling expenses. He figures that it costs $1.75 to make each cake and he charges $6.50 per cake. Let x represent the number of cakes sold. Express the revenue R and Cost C as functions of x. Then find how many cakes will he need to sell before he will make a profit
Final answer:
The baker's revenue R can be expressed as R = x * 6.50, and the cost C can be expressed as C = 45 + 25 + (x * 1.75). To find the number of cakes he needs to sell before making a profit, we set the revenue equal to the cost and solve for x. The baker will need to sell at least 15 cakes before making a profit.
Explanation:
To express the revenue R as a function of x, we can use the equation R = x * 6.50. This is because the revenue is the number of cakes sold multiplied by the price per cake. So, every cake sold contributes $6.50 to the revenue.
To express the cost C as a function of x, we can use the equation C = 45 + 25 + (x * 1.75). The initial fixed costs of $45 for reserving a booth and $25 for traveling expenses are added to the variable costs of $1.75 per cake multiplied by the number of cakes sold.
To find the number of cakes he needs to sell before making a profit, we need to set the revenue equal to the cost and solve for x:
R = C => x * 6.50 = 45 + 25 + (x * 1.75)
Combining like terms, we get:
4.75x = 70
x = 70 / 4.75
x ≈ 14.74
Since you cannot sell a fraction of a cake, the baker will need to sell at least 15 cakes before making a profit.

A college student borrow $1,500 for 3 months to pay for a semester of school. If the interest is $30.94, find the monthly payment (Round to the nearest cent.)
Answer:
Hence, the monthly payment to the nearest cent is 510.31
Step-by-step explanation:
Consider the provided information,
A college student borrow $1,500 for 3 months to pay for a semester of school.
Let us consider the monthly payment is $x.
If he pay $x for next 3 months, then the total amount student paid in 3 month is: 3x
The interest is $30.94 for 3 months.
Student pay all the borrowed money and interest in 3 months.
That means he pay $1,500 + $30.94 in 3 months while the monthly payment was 3x.
This can be written as:
[tex]3x = 1500+30.94[/tex]
[tex]3x = 1530.94[/tex]
[tex]x = \frac{1530.94}{3}[/tex]
[tex]x = 510.31[/tex]
Hence, the monthly payment to the nearest cent is 510.31
A fireman, 57.6 m away from a burning building, directs a stream of water from a fire hose at an angle of 35.2° above the horizontal. if the initial speed of the stream is 42.7 m/s, at what height will the stream of water strike the building?
First calculate the time it takes to reach the building using the x-component of the velocity.
t = 57.6 m / (42.7 m/s * cos35.2) = 1.65 s
Then we calculate the height y using the y-component of the velocity:
y = (42.7 m/s * sin35.2) * 1.65 s – 0.5 (9.81 m/s^2) (1.65 s)^2
y = 11.26 m
Final answer:
Using principles of projectile motion and given the initial speed, angle of projection, and horizontal distance, the stream of water from the fire hose will strike the building at a height of approximately 20.3 meters.
Explanation:
To determine at what height the stream of water will strike the building, we need to apply the principles of projectile motion. We are given the initial speed of the water stream (42.7 m/s), the angle of projection (35.2 degrees), and the horizontal distance from the fireman to the building (57.6 meters).
First, we separate the initial velocity into horizontal (ux) and vertical (uy) components:
ux = u * cos(θ) = 42.7 m/s * cos(35.2°) = 42.7 m/s * 0.8192 ≈ 35.0 m/s
uy = u * sin(θ) = 42.7 m/s * sin(35.2°) = 42.7 m/s * 0.5759 ≈ 24.6 m/s
Next, we use the formula for the horizontal motion to find the time (t) it takes for the water to reach the building:
x = ux* t => 57.6 m = 35.0 m/s * t => t ≈ 1.65 s
Finally, we can calculate the vertical distance (y) using the time and the vertical component of the velocity:
y = uy*t - (1/2) * g * t2 = 24.6 m/s * 1.65 s - (0.5 * 9.81 m/s2 * (1.65 s)2) ≈ 20.3 m
Therefore, the stream of water will strike the building at a height of approximately 20.3 meters above the ground.

Dr. Hong prescribed 0.019 liter more medicine than Dr. Tannenbaum. Dr. Evans prescribed 0.02 less than Dr. Hong. Who prescribed the most medicine. Who prescribed the least
Who prescribed the
most medicine?
It would be Dr. Hong. This is because Dr. Hong has prescribed more than Dr.Tannenbaum and Dr.Evans.
Who prescribed the least?
It would be Dr.Evans. Because he has prescribed 0.02
less than Dr.Hong and 0.01 less than Dr.Tannenbaum.
Dr. Hong prescribed most medicine and Dr. Evan prescribed less medicine among all other doctors.
Further explanation:
Given:
Dr. Hong prescribed 0.019 liter more medicine than Dr. Tannenbaum.
Dr. Evans prescribed 0.02 liter less than Dr. Hong.
Calculation:
Consider Dr. Tannenbaum prescribed x liter medicine.
It is given that the Dr. Hong prescribed 0.019 liter more than the Dr. Tannenbaum.
Therefore Dr. Hong prescribed [tex]x+0.019{\text{liter}}[/tex] medicine.
It is also given that the Dr. Evans prescribed 0.02 liter less than Dr. Hong.
Therefore, Dr. Evans prescribed [tex]\left({x+0.019-0.02}\right){\text{liter}}[/tex] medicine.
So the Dr. Evans prescribed exactly [tex]\left({x-0.001}\right){\text{liter}}[/tex].
Therefore the medicine prescribed by Dr. Hong is [tex]\left({x+0.019}\right){\text{liter}}\\[/tex].
The medicine prescribed by Dr. Tannenbaum is x liters.
The medicine prescribed by Dr. Evans is [tex]\left({x-0.001}\right){\text{liter}}[/tex].
Arrange all doctors in ascending order with their prescribed medicine.
Dr. Hong > Dr. Tannenbaum > Dr. Evans
So it is obtained from the above expression that the Dr. Evans prescribed less medicine and Dr. Hong prescribed most medicine than other doctor.
Thus, Dr. Hong prescribed most medicine and Dr. Evans prescribed less medicine among all other doctors.

Compute, in centimeters and in meters, the height of a basketball player who is 6 ft 6 in. tall.
Answer:
Height in cm =198.12 cm
Height in m =1.9812 m
Step-by-step explanation:
To make this conversion we have to get the conversion rate from feet and inches to centimeters.
Each feet is 30.48 cm. And each inch is 2.54 cm This is the rate of conversion.
So, to get the height of the basketball player we have to multiply the height in feet and inches by the rate.
6 ft x 30.48 cm= 182.88 cm
6 in x 2.54 cm= 15.24 cm
Adding both, height in cm =198.12 cm
Rate of conversion cm to m= 100 cm are a meter
We divide the height in cm by 100 to get the height in m
Height in m =1.9812 m
