Brandi jogged for 2/1:2 mikes in 30 minutes sharana jogged 3/1:2 miles in 3:4hours who jogged at a slower rate
Based on the information provided, neither Brandi nor Sharana jogged at a slower rate.
What is rate?Rate can be defined as the speed at which an event happens or an object moves over a particular period of time.
It is also known as the ratio at which two or more term, quantities or objects with different units are compared.
The formula for rate is expressed as;
Rate = distance/ time
From the information given, we have that;
Brandi jogged a distance = 2/1 : 2 = 2 × 1/ 2 = 1 mile in 30 minutesSharana jogged a distance = 3/1 : 2 = 3/ 2 = 1. 5 miles in 3/ 4 × 60 minutes = 45 minutesSubstitute the values
Brandi's rate = 1/ 30 = 0. 03
Sharana's rate = 1. 5/ 45 = 0. 33
From the values gotten, we can see that neither Brandi nor Sharana jogged at a slower rate.
Thus, neither Brandi nor Sharana jogged at a slower rate.

B
v=D
y = -x +2 an equation in slope-intercept form of the line that bisects the angle.
What exactly does slope intercept mean?
A method of formulating a line's equation that makes it simple to identify the slope and y-intercept is known as the slope-intercept form. The point where the line crosses the y-axis is known as the y-intercept, and the slope refers to how steep the line is.Given:
Angled formed by ray BA and ray BC is 90 degrees.
To find:
The equation of line that bisects the angle formed by ray BA and ray BC.
If a line bisects the angle formed by ray BA and ray BC, then it must be passes through point B and makes angles of 45 degrees with ray BA and ray BC.
It is possible if the line passes though point B(-1,3) and other point (-2,4).
Equation of line is
y - y₁ = y₂ - y₁/x₂ - x₁ ( x - x₁)
y - 3 = 4 - 3 / - 2 - ( -1) ( x - ( -1)
y - 3 = 1/-1 ( x + 1 )
y - 3 = -x -1
Add 3 on both sides
y = -x -1 + 3
y = -x +2

The sum of two numbers is 14. One number is two less than three times the other. Write an equation to represent the situation
using as a variable.
Answer:
Number 1 is 4
Number 2 is 10
Step-by-step explanation:
Number 1 is x
Number 2 is 3x - 2
so x + (3x - 2) = 14
x + 3x - 2 = 14
4x = 14 + 2
4x = 16
x = 4
so
Number 1 is 4
Number 2 is 3(4) - 2 = 10
Write a function that gives the length of the hypotenuse of an isosceles right triangle with side length s. Evaluate the inverse of the function to find the side length of an isosceles right triangle with a hypotenuse of 6 in.
A function that gives the length of the hypotenuse of an isosceles right triangle with side length s is given by h(s)=s√2 and the length of the side of the triangle is approximately 4.24 inches.
The hypotenuse of a right angled triangle is defined as the longest side of the triangle. The hypotenuse is also located opposite the right angle.
From the Pythagorean Theorem we know that for a right angled triangle, the sum of the square of the legs of the triangle is equal to the square of the hypotenuse.
Given legs of the right triangle is s. Let us consider a function h(s) for the hypotenuse.
Therefore we can define the function h(s) as
h(s)=s√2
The inverse of the function can be written as
y=s√2
or, s=y²/2
Hence the inverse function is:
h⁻¹(s)=s²/2
Now for hypotenuse = 6 inches.
Each side can be calculated using the inverse function h⁻¹(s)=s²/2.
s=6÷√2
or, s=4.242...
Hence the length of the side of the triangle is approximately 4.24 inches.

Find the sum of all decent fractions whose denominator is equal to 20
a) 10
b) 20
c) 9.5
d) 8
Answer:
B,A
Step-by-step explanation:
hope that's right
The sum of all decent fractions with a denominator of 20 is 4.
Thus, option (d) is correct.
To find the sum of all decent fractions whose denominator is equal to 20, consider fractions with numerators that are coprime to 20 (i.e., the numerator and 20 have no common factors other than 1).
The decent fractions with a denominator of 20 can be written as:
1/20, 3/20, 7/20, 9/20, 11/20, 13/20, 17/20, and 19/20.
To find the sum, add up these fractions:
Sum = 1/20 + 3/20 + 7/20 + 9/20 + 11/20 + 13/20 + 17/20 + 19/20
Sum = (1 + 3 + 7 + 9 + 11 + 13 + 17 + 19) / 20
Sum = 80 / 20
Sum = 4
Therefore, the sum of all decent fractions with a denominator of 20 is 4.
Thus, option (d) is correct.

You can select the value of y when the function crosses the y-axes(y-intercept) and another point and follow the same procedure I am going to do here.
What is a linear function?A linear function is modeled in slope-intercept form by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, we have that when x = 0, y = 3, hence the slope is of b = 3. When x = -1, y = 5, hence the slope(change in y divided by change in x) is given by:
(3 - 5)/(0 - (-1)) = -2.
Hence the function is:

Does every function have an inverse which is a function? Does every relation have an inverse which is a relation?
No, all functions do not have an inverse functions. Those that do exists named invertible.
What is meant by inverse function?The inverse function of a function f in mathematics exists a function that reverses the operation of f. If the inverse of f exists, it is shown by the f⁻¹. The inverse of f exists if and only if f is bijective.
An inverse in mathematics is a function that "undoes" another function. In other words, if f(x) produces y, then y entered into the inverse of f produces x. An invertible function is one that has an inverse, and the inverse is represented by the symbol f ⁻¹.
In mathematics, an inverse function (or anti-function) exists as a function that "reverses" another function: if the function f used to an input x gives a result of y, then using its inverse function g to y gives the result x, i.e., g(y) = x if and only if f(x) = y.For a function f: X → Y to have an inverse, it must have the property that for every y in Y, there is exactly one x in X such that f(x) = y. This property ensures that a function g: Y → X exists with the necessary relationship with f.No, all functions do not have an inverse functions. Those that do are called invertible.

For each annual rate of change, find the corresponding growth or decay factor. -0.1%
The decay factor for the annual rate of change of -0.1 % is 0.999.
A quantity must vary by a specific percentage each time period in order for growth or decay to be exponential.
With the function displayed to the right, you may represent exponential growth or decay.
A(x) = a( 1 + r)ˣ
Where A is the amount after x time periods, a is the initial amount, x is the number of time periods, and r is the rate of change.
Now, we have the annual rate of change as:
r = - 0.1 % = - 0.1 / 100 = - 0.001
From the function A(x) = a( 1 + r)ˣ , the corresponding factor is 1 + r.
So, let B = 1 + r
B = 1 + r
B = 1 + (- 0.001)
B = 1 - 0.001
B = 0.999
Now, the value of B is less than 1 therefore, the corresponding decay factor is 0.999.

a. Han wrote (1/2, 0) as x-intercept of the line instead of (2, 0).
b. The x-intercept: (2, 0)
The y-intercept: (0, 5)
What is the X-intercept and Y-intercept of a Line?The y-intercept of a line is the corresponding value of y when the value of x is equal to zero.
On the other hand, the x-intercept of a line is the corresponding value of x when the value of y is equal to zero.
Y-intercept is (0, b), while x-intercept is (b, 0), where b is the value of the point on the axis that is being intercepted.
In slope-intercept form, y = mx + b or y = b + mx, the y-intercept is represented as b, which is (0, b).
Given the equation in slope-intercept form as y = 5 - 10/4x, the y-intercept, b = 5. Therefore, is expressed as (0, 5).
To find the x-intercept, substitute y = 0 into y = 5 - 10/4x:
0 = 5 - 10/4x
Solve for x
-5 = -10/4x
-20 = -10x
-20/-10 = x
x = 2
The x-intercept is (2, 0), while the y-intercept is (0, 5).
Therefore:
a. The Han got the x-intercept wrong, it should be (2, 0), not (1/2, 0).
b. The x-intercept is (2, 0), while the y-intercept is (0, 5).
