Draw a vertical line through 1 on the x axis. Extend this vertical line as far up and down as you can.
Notice how the vertical line crosses the blue curve. Mark this point. Then draw a horizontal line from this point to the y axis. The horizontal line will touch -4 on the y axis. So that means the point (1,-4) is on the curve.
If the input it is x = 1, then the output is y = -4
So that's why the answer is choice A

y= 3.25x- 1
y= 9.75x- 14

Answer:
[tex]y=3.25x-1[/tex]
Step-by-step explanation:
step 1
Find the slope
we have the points
(2,5.5) and (5,15.25)
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
substitute
[tex]m=\frac{15.25-5.5}{5-2}[/tex]
[tex]m=\frac{9.75}{3}=3.25[/tex]
step 2
Find the equation of the line in slope intercept form
y=mx+b
we have
[tex]m=3.25\\point\ (2,5.5)[/tex]
substitute
[tex]5.5=3.25(2)+b[/tex]
solve for b
[tex]b=-6.5+5.5=-1[/tex]

In recent years, 23.8% of all registered doctors were female. If there were 57,800 female registered doctors that year, what was the total number of registered doctors?
Answers
To find out the number of registered doctors, we divide the number of female doctors by 23.8% as a decimal (which is just 0.238):
57,800 ÷ 0.238 = 242,857
-------------------------------------------------------------------------------------------------------------
Answer:
So there are 242,857 registered doctors.
Final answer:
To determine the total number of registered doctors, one can use the percentage of female doctors and the number of female doctors to calculate the overall total. By dividing 57,800 by 0.238, you find there were approximately 242,857 registered doctors.
Explanation:
The question asks for the total number of registered doctors, given that 23.8% are female and there are 57,800 female registered doctors. To find this, we use the formula:
Percentage (%) = (Part/Total) × 100
First, we express the percentage as a decimal by dividing it by 100, so 23.8% becomes 0.238. Next, we will rearrange the formula to solve for the Total:
Total = Part / Decimal Percentage
So we have:
Total = 57,800 / 0.238
Doing the calculation:
Total = 242,857 (approx.)
Therefore, the total number of registered doctors is approximately 242,857.

Answers
Frank’s electric bill has a cycle day of the 3rd
And the due date of the bill is 8 days later
that is 3+8 = 11th of that month is the due date
The bill is to be paid by 11th
But 1 day grace period is given
So
11+1
=12

Answers
Answer:

2/9 yd2
hope i helped :)
The required area of the rectangle with dimensions 13 yards long and 23 yards wide is 299 square yards.
How to calculate the area of the rectangle?In order to evaluate the area of the rectangle we must know the length and width of the rectangle and put this measure of length and width of the rectangle in the formula of area,
Area of the rectangle = length × width
Here,
From the question,
we have length = 23 yard and width = 13 yards
Area of the rectangle = 23 × 13
= 299 square yards
Thus, the required area of the rectangle with dimensions 13 yards long and 23 yards wide is 299 square yards.

Answers
answer
7/3
Answer:
Option C is correct
7/3
Step-by-step explanation:
Formula for slope is given by':
[tex]\text{Slope} = \frac{y_2-y_1}{x_2-x_1}[/tex] ....[1]
As per the statement:
The graph shows the best fit line scatter-plot.
Consider two points i.e
(3,12) and (6, 19)
Substitute these points in [1] we have;
[tex]\text{Slope} = \frac{19-12}{6-3}[/tex]
⇒[tex]\text{Slope} = \frac{7}{3}[/tex]
Therefore, the slope of the line of best-fit in the scatter plot is, 7/3

which number dose 5 represent a value 10 times the value represented by 5 in 35,187
Answers
In 35,187, the digit 5 represents 50,000. Ten times this value is 500,000. Therefore, in the new number, the digit 5 represents 500,000.
To find the value represented by the digit 5 in the number 35,187, we need to consider its place value. In the given number, 5 is in the ten-thousands place, which means it represents 5 * 10,000 or 50,000.
Now, we're asked to find a number where 5 represents a value ten times that of its representation in 35,187. So, we need to multiply 50,000 (the value represented by 5 in 35,187) by 10.
50,000× 10 = 500,000.
Therefore, in the new number, the digit 5 represents 500,000.
To summarize, the number where 5 represents a value ten times its representation in 35,187 is 500,000.

This cylindrical fish tank has a height of 36 inches and a diameter of 30 inches. What is the volume of the fish tank?
Answers
area of cross-section x the height.
First lets work out the area of the cross-section. Since the cross-section is a circle, we use the formula π x r²
Halve the the diameter to get the radius, so we can use the formula:
30 / 2 =15
Area of cross-section
π x 15² = 706.8583471 inches²
Now that we know the area of the cross-section, we multiply this by the height to get the volume.
706.8583471 x 36 = 25446.90049
= 25446.90 (2dp)
So the volume of the cylindrical fish tank is 25446.90
The volume of the cylindrical fish tank is 25446.90 inches cube.
What is the volume of a right circular cylinder?Suppose that the radius of considered right circular cylinder be 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
The formula for the volume of a cylinder is:
The area of cross-section x the height.
Since the cross-section is a circle, we use the formula π x r²
Radius= 30 / 2 =15
Thus, Area of cross-section
π x 15² = 706.8583471 inches²
Now that we know the area of the cross-section,
706.8583471 x 36 = 25446.90049
= 25446.90 (2dp)
So. the volume is 25446.90
