An equation for the function graphed above is \(y = \frac{4(x - 1)}{(x + 1)(x - 4)}\).
What is a vertical asymptote?In Mathematics and Geometry, the vertical asymptote of a function simply refers to the value of x (x-value) which makes its denominator equal to zero (0).
By critically observing the graph of this rational function shown above, we can logically deduce that its vertical asymptotes include the following;
x = -1 ⇒ x + 1 = 0.
x = 4 ⇒ x - 4 = 0.
In this context, an equation that represent its denominator is given by the following quadratic function:
Q(x) = (x + 1)(x - 4)
Assuming the leading coefficient of the function P(x) is represented by a;
P(x) = a(x - 1)
By evaluating and solving for the leading coefficient "a" in this function, we have;
f(x) = P(x)/Q(x)
f(x) = a(x - 1)/[(x + 1)(x - 4)]
f(0) = a(0 - 1)/[(0 + 1)(0 - 4)]
f(0) = -a/[(1)(-4)]
f(0) = a/4
Since the y-intercept of this graph is located at (0, 1), the value of the leading coefficient (a) can be calculated as follows;
1 = a/4
1 = a/4
a = 4 × 1
a = 4
By substituting the value of the leading coefficient (a) into the function, we have the following;
f(x) = P(x)/Q(x)
f(x) = y = 4(x - 1)/[(x + 1)(x - 4)]
\(f(x) = y = \frac{4(x - 1)}{(x + 1)(x - 4)}\)

Seventy percent of the children went on the excursion. If 27 stayed at school, how many went?
By using the Unitary Method we get the number of children who went on an excursion was 63. Thus, the total number of children at school is 90.
We are given that,
No. of children who stayed at school is 27,
Also, 70% of the children went on an excursion.
Suppose, the total number of children in percentage is 100%
Out of which 70% went on an excursion
Thus, the children who stayed at school is 100% - 70% = 30%
By using the Unitary method, we can find out the number of 70% of children.
If 30% of the children are 27
Then 70% of the children are = 27 × 100
30
= 63
∴ the total no. of children in the school = 27 + 63
= 90

The basic rate pay is K8.20. If the overtime is paid at time-and-a-quarter, what is the overtime rate of pay?
The overtime rate of pay is K10.25.
The overtime rate of pay can be calculated by multiplying the basic rate pay by the time-and-a-quarter factor. In this case, the basic rate pay is K8.20.
To determine the overtime rate of pay, we need to calculate one-quarter (1/4) of the basic rate pay, and then add that amount to the basic rate pay. One-quarter of K8.20 is calculated as (1/4) * K8.20 = K2.05.
By adding the calculated overtime amount to the basic rate pay, we get the overtime rate of pay: K8.20 + K2.05 = K10.25.
Therefore, the overtime rate of pay is K10.25.

A map shows the vertices of a campsite are (25,10), (25,-5), (-5,-5), and (-5,10). The vertices of your tent are (0,-3), (0,6), (10,6), and (10,-3). The coordinates are measured in feet. What percent of the campsite is not covered by your tent?
The percent of the area that is not covered is 80 percent
How to calculate the area that is not coveredIn mathematics area is defined as the absolute or total space that an object or shape occupies. It is usually measured using centimeters, cm ² square or the use of meter square m ².
area of tent
= (10 - 0) * (6 - (-3))
= 90
The area of the campsite would be:
(25 - (-5) x (10 - (-5))
= 450
Then the area would be 450 - 90
= 360
the percentage that is not covered by tent = 360 / 450 x 100

Given f(x)=x², after performing the following transformations: shift upward 98 units and shift 93
units to the right, the new function g(x) =
The new function g(x) after performing the given transformations is g(x) = (x - 93)² + 98
How to determine the new functionFrom the question, we have the following parameters that can be used in our computation:
f(x) = x²
The transformation that shifts it upward 98 units is g(x) = f(x) + 98,
While the transformation that shifts it 93 units to the right is g(x) = f(x - 93).
To apply both transformations, we can first shift the function f(x) to the right by 93 units:
g(x) = f(x - 93) = (x - 93)²
Then we can shift the resulting function upward by 98 units:
g(x) = (x - 93)² + 98
Hence, the new function g(x) is: g(x) = (x - 93)² + 98

i) The point is shifted 3 units up.
So, the point becomes,
\(P^{\prime}(-1,7)\)ii) The point is shifted 3 units left.
So, the point becomes,
\(P^{\prime}(-4,4)\)iii) Since it is stretched vertically by the scale factor of 3.

The given expression expressed in the form (x+A)^2+B is (x - 6)² + 65
A = -6 and B = 65
Completing the squareFrom the question, we are to express the given expression in the form (x + A)^2+B by completing the square
The given expression is
x² -12x + 101
Using the completing the square method
x² -12x + 101
Divide the coefficient of x by 2 and then square it
The coefficient of x is -12
Dividing by 2, we get
-12/2 = -6
Squaring
(-6)²
Now, add and subtract this value from the expression
x² -12x + (-6)² + 101 - (-6)²
Then, we can write that
(x - 6)² + 101 - (-6)²
(x - 6)² + 101 - 36
(x - 6)² + 65
Thus,
The given expression expressed in the form (x+A)^2+B is (x - 6)² + 65
By comparison,
A = -6

Answer:

Step-by-step explanation:
1. First, we should know the slope-intercept form of any equation: y = mx + b.
y = y-coordinatem = slopex = x-coordinateb = y-intercept2. In the equation y = -2/3(x), it appears that the variables we can see are y, m, and x. However, the y-intercept, b, is still there with the value of 0.
Additionally, this is a proportional relationship because it follows the format y = kx. Proportional relationships always have a y-intercept of 0.Therefore, the y-intercept is 0.

The perimeter of the rectangle below is 76 units. Find the value of y.
The solution is : the value of y is 7.
Here, we have,
The perimeter of a rectangle is found by
P = 2 (l+w)
P = 2( 3y+3+2y)
Combine like terms
P = 2(5y+3)
We know the perimeter is 76
76 = 2(5y+3)
Divide each side by 2
76/2 = 2/2(5y+3)
38 = 5y+3
Subtract 3 from each side
38-3 = 5y+3-3
35 = 5y
Divide each side by 5
35/5 = 5y/5
7 =y
We want the length of AD = BC = 2y
AD = 2y=2*y = 14
Hence, The solution is : the value of y is 7.
