The coordinates of the endpoints of
DE
are D(–13,–10) and E(3,14). Point F is on
DE
and divides it such that DF:EF is 5:3.
What are the coordinates of F?
Write your answers as integers or decimals.
Using proportions, the coordinates of F are given as follows: F(-3,5).
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
Point F divides the segment such that DF:EF is 5:3, hence the point F is 5/8 of the way, that is:
F - D = 5/8(E - D).
The x-coordinate of F is given by:
x + 13 = 5/8(3 + 13)
x + 13 = 10
x = -3.
The y-coordinate of F is given by:
y + 10 = 5/8(14 + 10)
y + 10 = 15
y = 5.
The coordinates of F are given as follows: F(-3,5).

A rectangular field is 15m longer than it is wide.
The area of the field is 800m²
Work out the length of the field.
Give your answer to 1 decimal place.
The length of rectangular field is 36.76 m.
What is a length?Distance is quantified by length. A quantity with the dimension of distance is called length in the International System of Quantities. Most measurement systems choose a length base unit from which all other units are derived. The fundamental unit for length in the International System of Units is the metre.
The term "length" refers to the measurement or size of something from end to end. In other terms, it is the greater of the upper two or third dimension of a geometric shape or object.
Area of rectangle is L × W = 800
given L = 15 + W
W × ( 15+ W) = 800
15W + [tex]W^{2}[/tex] = 800
[tex]W^{2}[/tex] + 15W - 800 = 0

What is an isoquant?A contour line formed across a set of locations where the same quantity of output is produced while changing the quantities of two or more inputs is called an isoquant (derived from quantity and the Greek word iso, meaning equal). A factor of production, like as labor, money, land, or organization, is typically represented by the x and y axes on an isoquant. Another name for an isoquant is a "Iso-Product Curve" or a "Equal Product Curve."
The isoquant mapping deals with the cost-minimization, profit, and output maximization problems of producers, whereas an indifference curve mapping helps consumers address the utility-maximizing problem. Indifference curves and isoquants diverge much more.

Oliver and his friends like to collect and trade cards from a certain combat card game. Oliver used his allowance to purchase 5 booster packs and 4 premade decks, which included a total of 178 cards. For his birthday, he received 4 booster packs and 7 premade decks, which included a total of 264 cards. How many cards come in every booster pack and every premade deck?
Solving system of equations in two variable gives that the number of cards in every booster pack are 10 and number of cards in every premade deck are 32
What is system of equations in two variables and how to find its solution by substitution?
Let x and y be two variables and
a₁x+b₁y =c₁
a₂x+b₂y =c₂
Where a₁, a₂, b₁, b₂, c₁, c₂ are constants then we can solve these simultaneous equations by substitution take value of x from equation (1) and then put it in (2) to get an equation for y only and then solve for y. put value of y in equation (1) to get value of x.
Let the number of cards in every booster pack are x and the number of cards in every premade deck be y
Number of cards in 5 booster packs will be 5x and Number of cards in 4 premade deck will be 4y
As Oliver purchases 5 booster packs and 4 premade decks, which included a total of 178 cards.
Thus we get 5x + 4y = 178 .....(1)
Number of cards in 4 booster packs will be 4x and Number of cards in 7 premade deck will be 7y
As Oliver received 4 booster packs and 7 premade decks, which included a total of 178 cards.
Thus we get 4x +7y = 264 ...(2)
System of equations to be solved is
5x + 4y = 178 .....(1)
4x +7y = 264 ...(2)
From (1) , we get x = [tex]\frac{178-4y}{5}[/tex]
Put this value in (2)
[tex]4(\frac{178-4y}{5}) +7y= 264\\\frac{712}{5} -\frac{16y}{5} +7y = 264\\\frac{712}{5}-264=\frac{16y}{5} -7y\\ y= 32\\x= \frac{178-4(32)}{5 }\\ x=50/5\\x=10[/tex]
Therefore x=10 and y= 32
The number of cards in every booster pack are 10 and number of cards in every premade deck are 32

Step-by-step explanation:
Taylor makes $13 per hour at the grocery store. she always works between 10-15 hours per week to leave time for her homework and band practice. her gross wages can be modeled as w(h) = 13h, where h is the number of hours worked per week.
1. how much will her gross wages be if she works 12 hours this week?
2. what is the domain of this function?
3. what is the range of this function?
a) Her gross pay will be $156
b) The domain is D: [10, 15]
c) The range is R: [$130, $195]
What will be her gross wage if she works 12 hours this week?
We know that Taylor earns 13 dollars per hour on her job at the grocery store.
Then, if she works x hours in the week, her gross wage will be given by the linear equation:
g(x) = $13*x
So, if she works 12 hours, her gross pay will be:
g(12) = $13*12 = $156
what is the domain of this function?
we know that she works between 10 and 15 hours peer week, so the domain (set of the possible inputs of the function) is:
10 ≤ x ≤ 15 or [10, 15] in interval notation.
what is the range of this function?The range is the set of the outputs, the minimum of the rane is:
g(10) = $13*10 = $130
The maximum of the range is:
g(15) = $13*15 = $195
The range of the linear function is: [$130, $195]

Use version 2 of the arc length formula to find the length of the curve defined by 16xy^2 - y^6 = 9 from (9/16,1) to (9/8,2)
The arc length of the curve is 1.3125
What do you understand by length of the curve?The length of an arc is the separation of two locations along a segment of a curve.
A defined integral between the two points is used to calculate the area under a curve between two points. Integrate y = f(x) between a and b's limits to find the area under the curve y = f(x) between x = a & x = b. Integration within the defined bounds can be used to calculate this area.

Find the quadratic function with vertex (1,-2.9) and no intercepts.
Please help me I really just don't understand how to get the answer y+2.9 = -12(x-1)^2 as I need to mathematically prove this equation works.
Answer:
[tex]y+2.9=-12(x-1)^2[/tex]
Step-by-step explanation:
Vertex form of a quadratic function:
[tex]\boxed{y=a(x-h)^2+k}[/tex]
where:
(h, k) is the vertex.a is some constant.Given vertex: (1, -2.9)
Therefore:
h = 1k = -2.9Substitute the values of h and k into the formula:
[tex]\implies y=a(x-1)^2-2.9[/tex]
As the function has no x-intercepts, and the vertex is in Quadrant IV, the parabola will open downwards. Therefore, "a" will be negative. Without any further information, any number can be substituted for "a". Therefore, according to the given answer, let a = -12:
[tex]\implies y=-12(x-1)^2-2.9[/tex]
Note: If "a" was positive, the parabola would open upwards, which means there would be two x-intercepts (two points at which the curve intercepts the x-axis).
Finally, add 2.9 to both sides of the equation so that the equation is in the format of the given answer:
[tex]\implies y+2.9=-12(x-1)^2-2.9+2.9[/tex]
[tex]\implies y+2.9=-12(x-1)^2[/tex]

the store has a speaker equipment listed for a price of $100 per set of speakers there is a sale, the current selling price is 89.99 how much money does the customer save ?
The amount of money saved by the customer is $10.01
If the selling price is greater than the cost price, then the difference between the selling price and cost price is called profit or the money saved.
If the selling price is less than the cost price, then the difference between the cost price and the selling price is called loss or the money loss.
Profit/ Loss= Cost Price(CP)- Selling Price(SP)
When CP> SP, then we can say there is a profit.
When CP<SP, then we can say there is a loss.
When CP=SP, then we can say neither there is a loss nor profit.
Given data, CP= $100
SP= $89.99
Profit/Loss= CP- SP
= $100- $89.99
= $10.01
As we can see our result is positive, so there is a profit.
