The equation of tangent is,
⇒y = -1.4x + 28.8
Given that,
Centre of circle is at origin,
And it passes through (14, 7)
We know that the general equation of a circle is (x - h)² + (y - k)² = r²,
Where (h, k) is the center of the circle and r is the radius.
Since the circle passes through the point (14, 7) and has the origin (0, 0),
Now use the distance formula to find its radius,
radius = √((14 - 0)² + (7 - 0)²)
= √(14² + 7²)
= 221
Since the center is equidistant from (14, 7) and (0, 0),
The the midpoint of these two points:
⇒ (h, k) = ((14 + 0)/2, (7 + 0)/2)
= (7, 3.5)
Substitute the values we found for the radius and center into the general equation of a circle,
⇒ (x - 7)² + (y - 3.5)² = 221
Now the derivative of this circle equation:
⇒ d/dx [(x - 7)² + (y - 3.5²)] = d/dx [221]
⇒ [2(x - 7) + 2(y - 3.5)] dy/dx = 0
⇒ dy/dx = - (x - 7) / (y - 3.5)
Use the point (14, 7) to find the slope of the tangent line:
⇒ dy/dx = - (x - 7) / (y - 3.5)
⇒ dy/dx = - (14 - 7) / (7 - 3.5)
⇒ dy/dx = - 1.4
Use the point-slope form of a line to write the equation of the tangent line:
⇒ y - 7 = (-1.4)(x - 14)
Simplifying this equation, we get:
⇒ y = -1.4x + 28.8
This is the required equation of tangent.

im giving my friends 9 cupcakes thats 60 percent of my order how many more cupcakes do i need to get my order to 100 percent
Answer:
6 more cupcakes.
Step-by-step explanation:
60% of 15 is 9, so 15-9 is 6.
The number of cupcakes needed to get the order to 100% is 6 cupcakes.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
60% = 9 cupcakes
Multiply 100/60 on both sides.
100/60 x 60% = 100/60 x 9 cupcakes.
100% = 5 x 3 cupcakes
100% = 15 cupcakes
Thus,
6 more cupcakes are needed.

find the square root of 3.6 upto 2 decimal places. *With Solution I need*
Answer:
The square root is 1.90
Step-by-step explanation:
Given
\(x = \sqrt{3.6}\)
Required
Find x
Express 3.6 as 36/10
So, we have:
\(x = \frac{\sqrt{36}}{\sqrt{10}}\)
This gives
\(x = \frac{6}{\sqrt{10}}\)
Rationalize
\(x = \frac{6}{\sqrt{10}}*\frac{\sqrt{10}}{\sqrt{10}}\)
\(x = \frac{6\sqrt{10}}{10}\)
Using a calculator
\(\sqrt{10} \approx 3.16\)
So, we have:
\(x = \frac{6*3.16}{10}\)
\(x = \frac{18.96}{10}\)
\(x = 1.896\)
Approximate
\(x = 1.90\)

Ana works 25 hours a week at the library. If she is paid $10 an hour, and her net salary each week is $212.50, what percent of her salary is withheld for taxes?
Approximately 17.65% of Ana's salary is withheld for taxes.
To calculate the percentage of Ana's salary that is withheld for taxes, we need to determine the amount of tax withheld and then express it as a percentage of her net salary.
Number of hours worked per week (H) = 25 hours
Hourly wage (W) = $10
Net salary (S) = $212.50
Calculate the total earnings before taxes:
Total earnings = Hours worked * Hourly wage
Total earnings = 25 hours * $10/hour
Total earnings = $250
Determine the amount of tax withheld:
Tax withheld = Total earnings - Net salary
Tax withheld = $250 - $212.50
Tax withheld = $37.50
Calculate the percentage of salary withheld for taxes:
Percentage withheld = (Tax withheld / Net salary) * 100
Percentage withheld = ($37.50 / $212.50) * 100
Percentage withheld ≈ 17.65%
Therefore, approximately 17.65% of Ana's salary is withheld for taxes.

What is the present age of Alex if he is one- fourth the age of a his father and if the age of the father is doubled, it is 20 years less than 100 years?
take father's age as x
if it is doubled i.e 2x .we get the answer as 20 less than 100 which means 100-20=80
accordingly the equation will be 2x=80
x=40
given that ,
son is 1/4 th of his father
hence ,
son = 1/4×(x)
I.e, 1/4×40 =10
Hope it helps
Using a system of equations, it is found that Alex's present age is of 10 years.
For the system, we consider that:
Alex's present age is of x.His father's age is of y.He is one-fourth the age of a his father, hence:
\(x = \frac{y}{4}\)
If the age of the father is doubled, it is 20 years less than 100 years, hence:
\(2y = 100 - 20\)
\(2y = 80\)
\(y = \frac{80}{2}\)
\(y = 40\)
Then:
\(x = \frac{y}{4} = \frac{40}{4} = 10\)
Alex's present age is of 10 years.

graph the line passing through (−4,−1) whose slope is m=-4/5
Answer:
\(y=-\frac{4}{5}x-\frac{21}{5}\)
Step-by-step explanation:
The fastest way is to use point-slope form with \(m=-\frac{4}{5}\) and \((x_1,y_1)=(-4,-1)\):
\(y-y_1=m(x-x_1)\\y-(-1)=-\frac{4}{5}(x-(-4))\\y+1=-\frac{4}{5}(x+4)\\y+1=-\frac{4}{5}x-\frac{16}{5}\\y=-\frac{4}{5}x-\frac{21}{5}\)
To graph the line passing through (-4,-1) with slope m = -4/5, we can use the slope-intercept form of the equation of a line, which is:
y = mx + b
where m is the slope and b is the y-intercept.
Substituting m = -4/5, x = -4, and y = -1, we can solve for b:
-1 = (-4/5)(-4) + b
-1 = 3.2 + b
b = -4.2
Therefore, the equation of the line is:
y = (-4/5)x - 4.2
To graph the line, we can plot the given point (-4,-1) and then use the slope to find additional points. Since the slope is negative, the line will slope downwards from left to right. We can find the y-intercept by setting x = 0 in the equation:
y = (-4/5)x - 4.2
y = (-4/5)(0) - 4.2
y = -4.2
So the y-intercept is (0,-4.2).
Using this point and the given point (-4,-1), we can draw a straight line passing through both points.
Here is a rough sketch of the graph:

The total weight of the wall and the average dead load per foot of wall length can be calculated.
The total weight of the wall can be calculated by finding the weight of the bricks and frame, then adding the weight of the glass and sash. The total weight of the wall (W) is calculated as follows:
W = (0.25*40ft*11ft)*(weight of bricks + weight of frame) + (0.75*40ft*11ft)*(weight of glass + weight of sash)
The average dead load (F) per foot of wall length is calculated by dividing the total weight of the wall by the total length of the wall (L):
F = W/L = (0.25*40ft*11ft)*(weight of bricks + weight of frame) + (0.75*40ft*11ft)*(weight of glass + weight of sash) / (40ft)

There are 9.5 ounces of juice in a container. An additional 1.75 ounces of juice are poured into the container each second. How many ounces of juice are in the container after 6 seconds? Enter your answer in the box
By concept of capacity and the assumption of constant flow rate, the amount of ounces of juice in the container after 6 seconds is 20 ounces.
How to determine the final capacity of a container
Given that the additional juice is added to the container at constant rate. Hence, the final capacity (C'), in ounces is equal to the sum of the initial capacity (C), in ounces, and the product of the flow rate (q), in ounces per second, and time (t), in seconds.
C' = C + q · t (1)

After analyzing, it can be concluded that the functions f and g are:
A. f(0) is larger than g(0).
B. f(3) is larger than g(3).
Two Functions is LargerTo determine which of the two functions is larger at any given point, one must compare the heights of the two functions at the same point on the x-axis. At point x=0, the height of the f(x) function is larger than the height of the g(x) function, so f(0) is larger than g(0).
Similarly, at point x=3, the height of the f(x) function is larger than the height of the g(x) function, so f(3) is larger than g(3).
To compare which of two functions is larger at any given point, we need to compare the heights of the two functions at the same point on the x-axis. For example, at x=0, the height of the f(x) function is larger than the height of the g(x) function, so f(0) is larger than g(0). The same comparison can be made at any other point on the x-axis.
For example, at x=3, the height of the f(x) function is larger than the height of the g(x) function, so f(3) is larger than g(3). This comparison can be done for any point on the x-axis, which will allow us to determine which of the two functions is larger at any given point.
