In Exercises 13-15, use f(x) = x² and g(x) = 4x - 6 to find h(x).
13. h(x) = f(x) - g(x)
14. h(x) = f(g(x))
15. h(x) is the inverse of g(x)
The value of the function h(x) is x² - 4x +6 and 4-6 x².
What is a formula for a function?Any function's x-intercept, y-intercept, and slope can be calculated using function formulas. You could also determine a quadratic function's vertex. Additionally, the function can be graphed for various x values.
Simply adding the values of the functions f(x) and g will yield the value of the function f(x) and g(x).
Therefore, we get
f(x) = x² and we have g(x) = 4x - 6
h(x) = f(x) - g(x)
h(x) = x² - 4x +6
h(x) = f(g(x))
= x²( 4x - 6)
= 4-6 x²
h(x) is the inverse of g(x)
= inverse of 4x - 6
= 1/ 4x - 6

From the exponential function, the average rate of change from year 1 to year 4 is 62.43, the average rate of change from year 5 to year 8 is 67.57 and the rate of change per year is 65
What is Exponential FunctionAn exponential function is a type of function that involves a variable in an exponent. It is of the form f(x) = a⋅b^x where a and b are constants and b > 0, b ≠ 1. The input to the function, x, is the exponent that the base, b, is raised to. The output, f(x), is the result of raising the base to the exponent.
In this problem, we have to calculate the rate of increase per year.
Data;
rate = 2%
P = 3000
The exponential growth can be calculated by;
A = P(1 + r)ⁿ
In year 1
A = 3000(1 + 0.02)¹

° Draw a segment {ST} of length 9 cm.
°Draw the circle with center T and radius 4 cm
.
° Draw the circle with diameter {ST}
° The two circles intersect at A and B. Without measuring, give the length of the segments {TA} and {TB}:
The length of segments TA and TB are both 4 cm.
How to determine the diagram and the lengthsTo solve this problem, we can use the properties of circles and the relationship between the radius and the diameter.
Since the radius of the circle with center T is 4 cm, the diameter of this circle is 2 * 4 = 8 cm.
Since the length of segment ST is 9 cm, the diameter of the second circle is also 9 cm.
Since the radius of the circle with center T is 4 cm, the radius of the second circle is also 4 cm.
Since the two circles intersect at points A and B, the segments TA and TB are equal in length.The length of segment TA and TB is the radius of the second circle, which is 4 cm.
Therefore, the length of segments TA and TB are both 4 cm.

In triangle JKL, angles J and L each measure 51° and JK = 18. Triangle PQR is similar to triangle JKL, where J corresponds to P, K corresponds to Q, and QR = 36. Which expression represents the length of segment PR?
Answer:
Step-by-step explanation:
Triangle JKL is a 51-51-78 triangle, since the angles in a triangle must add up to 180°. Since triangle PQR is similar to triangle JKL, it must also be a 51-51-78 triangle. Since corresponding sides in similar figures are in proportion, we can set up a proportion to find the length of PR:
(PR)/(JK) = (PQ)/(JL) = (36)/(18)
Cross multiplying and solving for PR, we find:
PR = (JK) * (PQ)/(JL) = 18 * 36/18 = 36

Answer:
both are right
Step-by-step explanation:
2/5x = 14
multiply both sides by 5/2:
(5/2)(2/5)x = 14(5/2)

The measurement of the hypotenuse is obtained as 9 units using the Pythagoras theorem.
What is Pythagoras Theorem?
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side.
According to the graph -
The perpendicular measures 4 units.
The base measures 3 units.
To find the hypotenuse g apply the Pythagoras theorem -
(hypotenuse)^2=(base)^2+(perpendicular)^2
(g)^2=(3)^2+(4)^2
(g)^2=9+16

Please solve the ques below:
Answer:
510 miles
Step-by-step explanation:
A B
Rate 80 120
Time x x - 2
Distance
Distance = rate x time
A's distance
d = 80x
B's distance
d = 120(x -2)
The distances equal each other when B catches up to A. Set the equations equal to each other and solve for the time
80x = 120(x -2) Distribute the 120
80x = 120x - 240 Subtract 120x from both sides
-40x = -240 Divide both sides by -40
x = 6
After 6 hours, B caught up with A. Substitute 6 for t and find the distance. You can use A or B.
d= 80x
d = 80(6)
d = 480
We need to add another 30 miles to get to the next town.

What are the distance formula and midpoint of a segment?
The distance formula is a mathematical formula that can be used to determine the distance between two points in a coordinate plane. The distance between two points (x1, y1) and (x2, y2) is given by the formula:
[tex]d = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]
The midpoint of a segment is a point that is exactly in the middle of a line segment. Given the endpoints of the line segment, (x1, y1) and (x2, y2) the coordinates of the midpoint, (x, y) can be calculated using the following formulas:
x = (x1 + x2) / 2
y = (y1 + y2) / 2
The given points are (-8, 6) and (-2, -2).
Given two points A(x1, y1) = (-8, 6) and B(x2, y2) = (-2, -2), we can use the distance formula to find the length of the line segment AB. The distance formula is:
[tex]d = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}\\\\d= \sqrt{((-2) - (-8))^2 + ((-2) - (6))^2}\\\\d=\sqrt{36 + 64}\\\\d=\sqrt{100}\\\\d=10[/tex]
The length of AB would be 10.
To find the coordinates of the midpoint of AB, we can use the midpoint formula:
x = (x1 + x2) / 2
y = (y1 + y2) / 2
Plugging in the values for A and B, we get:
x = (-8 + (-2)) / 2 = -5
y = (6 + (-2)) / 2 = 2
The coordinates of the midpoint of AB are (-5, 2).
Hence, the length of AB would be = 10 units and the midpoint of segment AB would be (-5, 2).

Given A(0, a) and B(b, 0) , find coordinates of C so that the orthocenter of triangle ABC lies on the triangle.
The coordinate of the point C is (0, a)
How to determine the coordinates of point CFrom the question, we have the following parameters that can be used in our computation:
A = (0, a)
B = (b, 0)
As a general rule, the orthocenter of a triangle is a point located at the intersection of the lines containing the altitudes of the triangle.
This means that we start by calculating the equation of the altitude from B to line AC.
A linear equation is represented as
y = mx + c
Where
slope = m
y-intercept = c
Using the above as a guide, we have the following:
slope = (y₂ - y₁)/(x₂ - x₁)
This gives
m(BC) = (0 - 0)/(b - 0) = 0
y-intercept (c) = a
So the equation of the line BC is
y = 0 * x + a
y = a
For line AC, we have
m(AC) = (a - 0)/(0 - 0) = a/0 = undefined.
This means that the equation of the line AC is
x = 0
The equation x = 0 implies that the x-coordinate is always 0, irrespective of the y-coordinate e.g. (0, a)
At this stage, we have the coordinates of the points from lines AC and BC to be
(0, a) and (0, a)
Next, we calculate the C as follows
C = Midpoints of (0, a) and (0, a)
This gives
C = 1/2 * (0 + 0, a + a)
Evaluate
C = (0, a)
Hence, the coordinate of C is (0, a)

An online store charges $5 for shipping on all orders. They are having a sale on all t-shirts, $7 each! You and your friends are going to order some shirts. Write an expression that you could use to find the cost of the order.
Answer:
which one is correct about HRM?
The cost of the order can be expressed as 7x + 5, where x is the number of t-shirts ordered.
In this expression, "7x" represents the cost of the t-shirts, where each shirt is $7 and the number of shirts is represented by "x". The "$5" represents the flat shipping fee for the entire order, which does not change regardless of the number of shirts being ordered.
By adding the cost of the shirts and the shipping fee, we can find the total cost of the order. It's important to understand that the value of "x" must be specified to evaluate the expression.
For example, if 3 shirts are ordered, then x = 3 and the expression becomes:
7 * 3 + 5 = 26So the total cost of the order would be $26.
