the equation y=26.2x represents the number of miles y Conrad runs in x marathons. determine if there is a constant of variation. if so, explain what it represents:/
Final answer:
Yes, there is a constant of variation in the given equation y = 26.2x. The constant of variation represents the rate at which the number of miles y increases for every marathon x completed by Conrad.
Explanation:
Yes, there is a constant of variation in the given equation y = 26.2x. A constant of variation is represented by the coefficient or the number multiplied by x in the equation, which in this case is 26.2. It represents the rate at which the number of miles y increases for every marathon x completed by Conrad. So, for every marathon Conrad runs, the number of miles he runs increases by 26.2.

2. On rectangle ABCD below, if A is located at
(3, 4) and B is located at (7,6), is the slope
of BC ?
Answer: The slope of BC is -2.
Step-by-step explanation:
We know that a rectangle has all opposite sides equal and parallel.
Each interior angle is a right angle.
Therefore , if rectangle ABCD is a rectangle then , AB should perpendicular to BC. [ ∵ Angle between AB and BC is 90° .] (1)
Also , slope of line passing through (a,b) and (c,d) : [tex]\dfrac{d-b}{c-a}[/tex]
If A is located at (3, 4) and B is located at (7,6) .
Then , The slope of AB = [tex]\dfrac{6-4}{7-3}=\dfrac{2}{4}=\dfrac{1}{2}[/tex]
Also, the product of slopes of two perpendicular lines is -1.
Then , (Slope of AB) x (Slope of BC) = -1 [From (1)]
[tex]\Rightarrow\ \dfrac{1}{2}\times (\text{Slope of BC})= -1\\\\\Rightarrow\ \text{Slope of BC}=-2[/tex]
Hence, the slope of BC is -2.
A TV sells for 290$. If it's discounted at 15%, what is the discount
The discount is $43.50, making the price of the discounted TV $246.50.
15% = .15

The cost of 7 journals is $5 greater than the cost of 4 journals.
The cost of 7 journals is less than the cost of 4 journals plus a $5 novel.
The cost of 7 journals is less than the cost of 4 journals with a $5 off coupon. The cost of 7 journals is greater than the cost of 4 journals plus a $5 novel.
Answer:
The cost of 7 journals is less than the cost of 4 journals plus a $5 novel.
Step-by-step explanation:
Let
x -----> the cost of a journal
Verify each case
case 1) The cost of 7 journals is $5 greater than the cost of 4 journals
In this case the equation would be
[tex]7x=4x+5[/tex]
case 2) The cost of 7 journals is less than the cost of 4 journals plus a $5 novel.
so
[tex]7x<4x+5[/tex]
solve for x
subtract 4x both sides
[tex]3x<5[/tex]
divide by 3 both sides
[tex]x<\$1.67[/tex]
so
The cost of one journal must be less than $1.67
case 3) The cost of 7 journals is less than the cost of 4 journals with a $5 off coupon.
so
The inequality would be
[tex]7x<4x-5[/tex]
case 4) The cost of 7 journals is greater than the cost of 4 journals plus a $5 novel.
so
The inequality would be
[tex]7x>4x-5[/tex]

Find the product of 2x2(6x + 3). 12x3 12x3 + 3 12x3 + 6x2 2x2 + 6x + 3
Answer:
C. 12x³ + 6x²
Step-by-step explanation:
I'm an FLVS kid and got the question right, so I wanted to explain my answer:
You just have to use the distributive property for this one. Multiply 2x² by each term in the brackets.
2x²(6x + 3) ← original question for ref.
2x²(6x) = 12x³
2 · 6 = 12x² · x = x³("x" techniqually has a placeholder exponent of 1. To multiply two exponents with the same base, you just add the exponents. So x2 + x1 = x3.)2x²(3) = 6x²
2 · 3 = 6Keep the variable and exponent the sameSo the new terms are 12x³ + 6x²

Complete Question:
Option 1: $30 an hour plus a non-refundable deposit of $50.
Option 2: $20 an hour plus a non-refundable deposit of $75.
Kyle is renting a jetski for the day. If he can rent the jetski in 1-hour increments, what is the minimum number of hours must he rent the jetski for option 2 to be a better deal than option 1?
Answer:
Kyle must rent the jetski for three hours for option 2 to be a better deal than option 1
Solution:
Let "x" be the number of hours
Option 1: $30 an hour plus a non-refundable deposit of $50.Therefore,
Charge for option 1: 50 + 30x
For 1 hour,
Charge = 50 + 30(1) = 80
For 2 hours,
Charge = 30(2) + 50 = 110
For 3 hours,
Charge = 30(3) + 50 = 140
For 4 hours,
Charge = 30(4) + 50 = 160
Option 2: $20 an hour plus a non-refundable deposit of $75Charge for option 2 : 75 + 20x
For 1 hour,
Charge = 20(1) + 75 = 95
For 2 hours ,
Charge = 20(2) + 75 = 115
For 3 hours,
Charge = 20(3) + 75 = 135
For 4 hours,
Charge = 20(4) + 75 = 155
For the first two hours , the charge of option 2 is more than the rent of option 1
From 3 hours, option 2 will be better deal than option 1

Describe an easy way to find the square root
when the number is not a perfect square?
The product of a rational number multiplied by itself is called as a perfect square.,we can easily find out the square root for a number which is a imperfect square
Step-by-step explanation:
using the following formula we can find a square root for a number which is a imperfect square
X = Non perfect square
√x = (square root of nearest lower perfect square +(x - perfect square)÷2×(√perfect square )
[tex]√x = (square root of nearest lower perfect square +(x - perfect square)÷2×(√perfect square )[/tex]Example
√38
the nearest perfect root is 36
36 (√36=6)
so √38 = √36 + (38-36)/2√36
= 6 + 2/12
=6 + 1/6 = 6.166 (answer)
[tex]√38 the nearest perfect root is 36 36 (√36=6)so √38 = √36 + (38-36)/2√36 = 6 + 2/12=6 + 1/6 = 6.166 (answer)[/tex]
To find the square root of a non-perfect square, use estimation techniques or the quadratic formula if in relation to an equation. Use the imaginary unit i for square roots of negative numbers, and simplify by removing perfect squares when adding or subtracting radicals.
Finding the square root of a number that is not a perfect square can be done using a few different methods. One simple non-calculator method is to use estimation and refinement; start with an approximate guess and improve it. When dealing with negative numbers, remember that we use the imaginary unit i to denote the square roots of negative numbers. For example, a₂ can be written as 2i. Adding and subtracting radicals involves simplifying each radical by removing perfect squares and combining like terms.
For equations where the square root is part of a quadratic equation, ax²+bx+c = 0, if a, b, and c are non-zero, we should use the quadratic formula to find solutions. Estimation also applies when dealing with cube roots or higher, where we can start with an initial guess and use methods like calculus to refine it.
To estimate a surd like a₃ without a calculator, consider its place on the number line between two integers, knowing that a₃ is about 1.732. This helps get an approximate value which is often sufficient for many applications.
M=-2 (-3,4) how do you write it into slope intercept
Answer:
y = -2x - 2
Plug the x- and y-values into the appropriate spaces in the slope-intercept form and see which value for b would make the equation true:
4 = -2(-3) +/- ?
4 = 6 - 2
4 = 4
I don't know if this makes sense, I'm sorry if it doesn't but the answer is correct because it goes through the point (-3,4)
The answer is y = -2x - 2
You have to first plug the x- and y-values into the correct spots in the slope-intercept form and see which value for b would make the equation true.
4 = -2(-3) +/- ?
4 = 6 - 2

cos 2x - cos 8x
cos 2x + cos 8x
HELP PLS
Answer:
Cos 2x = Cos (5x-3x)
Cos(5x)Cos(3x) + Sin(5x)Sin(3x)
Cos 8x = Cos (5x + 3x)
Cos(5x)Cos(3x) - Sin(5x)Sin(3x)
Cos 2x - Cos 8x
= Cos(5x)Cos(3x) + Sin(5x)Sin(3x) -
[Cos(5x)Cos(3x) - Sin(5x)Sin(3x)]
= 2Sin(5x)Sin(3x)
Cos 2x + Cos 8x
= Cos(5x)Cos(3x) + Sin(5x)Sin(3x) +
[Cos(5x)Cos(3x) - Sin(5x)Sin(3x)]
= 2Cos(5x)Cos(3x)
= 2Sin(5x)Sin(3x) ÷ 2Cos(5x)Cos(3x)
2 gets cancelled out
Sin(5x)/Cos(5x) is Tan(5x)
Sin(3x)/Cos(3x) is Tan(3x)
Hence the fraction is identical to
Tan(5x)Tan(3x)

Ryan measures a rectangle that is 9 feet long and 5 feet wide. Teo measures a rectangle that has an area of 36 square feet. Which rectangle has the greater area/ explain
Answer:
Teo's rectangle has the greater area.
Step-by-step explanation:
Since a rectangle has the same opposite sides of parallel sides, you need to add or multiply 9 times 9 or 9 + 9 and 5 times 5 or 5 + 5. 9 x 9 or 9 + 9 equals 18, and 5 + 5 or 5 x 5 equals 10. Then, 18 and 10 is to be added. 18 + 10 is 28. So, that means Teo's rectangle has the greater area because, 28 is less than 36.
To compare the areas of the rectangles, calculate the area of each rectangle. Ryan's rectangle has a greater area of 45 square feet compared to Teo's rectangle which has an area of 36 square feet.
Explanation:To compare the areas of the two rectangles, we need to calculate the area of each rectangle. The area of a rectangle is found by multiplying its length by its width. For Ryan's rectangle, the length is 9 feet and the width is 5 feet, so the area is 9 feet × 5 feet = 45 square feet. For Teo's rectangle, we are given that the area is 36 square feet. Since 45 is greater than 36, Ryan's rectangle has the greater area.
