Problem 4
I recommend to draw a number line. Place the baseball park at 0 on the number line.
Then place Luke's house at -3. The distance from -3 to 0 is 3 units, to represent the 3 miles.
Place Logan's house at 2 on the number line.
To go from -3 to 2, move 5 units to the right. This is the longest distance possible because each person's house is on opposite sides of the baseball park.
To get the shortest distance possible, we'll place each person's house to the right of 0. This time each person's house is on the same side.
We'll move Luke from -3 to +3. Keep Logan at 2. The distance from 2 to 3 is 1 unit. This is the shortest distance possible.
Answers:
Shortest distance = 1 mile
Longest distance = 5 miles
===============================================
Problem 5
d = distance between Luke's house and Logan's house
Refer to the result of problem 4, where we found d = 1 the smallest possible value of d. And also d = 5 the largest possible value.
In other words: d is between 1 and 5, including each endpoint.
The compound inequality to set up is [tex]1 \le d \le 5[/tex]
The graph involves closed filled in circles at 1 and 5 on the number line. Shade the region between these endpoints. Closed endpoints visually tell the reader "include this endpoint".
Answers:
Inequality: [tex]\boldsymbol{1 \le d \le 5}[/tex]
Graph: Closed filled in circles at 1 and 5; shading in between
===============================================
Problem 6
The largest distance we previously found was 5 miles.
Luke traveled 0.5 miles so far, meaning he has at most 5-0.5 = 4.5 miles left to go.
Answer:
4.5 miles
Answer:
Q4
Shortest distance = 1 mile
Longest distance = 5 miles
Q5
1 ≤ d ≤ 5
Q6
4.5 miles
Step-by-step explanation:
A diagram does help for these questions
Q4
If both Luke and Logan's houses are on the same straight line in the same direction then the difference between their individual distances from the field will be the shortest distance.
See the first diagram
Shortest distance = 3 - 2 = 1 mile
However, if they lived in exactly opposite directions on a straight line then the distance would be the longest and would be 2 + 3 = 5 miles
--------------------------------------------------------------------------------
Q5
The compound inequality would be 1 ≤ d ≤ 5 where d represents all possible distances from the two homes.
(We can also write this as [1, 5] which is called interval notation)
See second figure for how this would be represented on a number line
------------------------------------------------------------------------------
Q6
Since we have determined the greatest distance between the two houses as 5 miles, and Luke has already biked 0.5 mile he has 5 - 0.5 = 4.5 miles left to bike

What is a quadratic function?Generally, A quadratic function is a type of polynomial function that has the form
f(x) = ax^2 + bx + c,
where
a, b, and c are constants and x is the variable.
The graph of a quadratic function is a parabola that opens either upward or downward, depending on the value of a. The vertex of the parabola is the point (h, k), where h = -b/2a and k = f(h). The roots of the quadratic function, or the x-coordinates of the points where the parabola crosses the x-axis, can be found using the quadratic formula: x = (-b ± √(b^2 - 4ac)) / 2a.
The range of a quadratic function in the form of y = ax^(2) + bx + c is all real numbers for a ≠ 0, and for a = 0,
the range is {c}. In this case, a = 2, so the range of y = 2x^(2) + 12x - 13 is all real numbers.

The range of the given quadratic equation is y ≤ 5.
What is a Quadratic Function?The quadratic function can represent a quadratic equation in the Standard form: ax²+bx+c=0 where: a, b and c are your respective coefficients. In the quadratic function, the coefficient "a" must be different than zero (a≠0) and the degree of the function must be equal to 2.
For solving a quadratic function you should find the discriminant: Δ=b²-4ac . And after that, you should apply the discriminant in the formula:[tex]x=\frac{-b\pm\sqrt{\Delta} }{2a}[/tex] .
The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined. While the domain is related to the values of x, the range is related to the possible values of y that the function can have.
For a quadratic function, the range is defined from the y-coordinate of the vertex ( [tex]y_v=\frac{-\Delta}{4a}[/tex]).
If a<0, the range is y≤ yv
If a>0, the range is y≥ yv
The question gives the following quadratic equation: -2x²+12x-13, then:
a=-2
b=12
c=-13
Δ= b²-4ac=12²-4*(-2)*(-13)=144-104=40
Therefore,
[tex]y_v=\frac{-\Delta}{4a}=\frac{-40}{4*(-2)}=\frac{-40}{-8}=5[/tex]
Thus, yv=5 and the range is ≤ 5.

To calculate the sale price, we need to find out how much the TV is discounted by, which we can do by multiplying the original price by the percentage discount (expressed as a decimal).
35% of the original price can be expressed as 0.35.
so,
Discount = 540 omr * 0.35 = 189 omr
To find the sale price, we can subtract the discount from the original price:
Sale price = Original price - Discount
Sale price = 540 omr - 189 omr
So the sale price is 351 omr.
