k= 6.64
assume that k pounds is the both percentile of breaking strength for this type of finishing line
p( x<k) = 0.60
p( x- 6.44/0.75 < k- 6.44/0.75)= 0.60
then k-6.44 /0.75 = 0.26

If f(x) =4x^6+ x^4+4,then what is the remainder when f(x) is divided by x-1
The remainder for the given polynomial is 9
A polynomial is an expression made up of variables, constants, and exponents that are combined using mathematical operations like addition, subtraction, multiplication, and division (No division operation by a variable). It is a function that only uses non-negative integer powers or positive integer exponents of a variable
Given f(x) = 4x^6+ x^4+4
Now f(x-1) = 0
X= 1
Substitute the x value in the function
f(x) = 4x^6+ x^4+4
f(x) = 4(1)^6+ (1)^4+4
f(x) = 4+ 1+ 4
f(x) = 9
Therefore the remainder for the given polynomial is 9

Find the dimensions of a rectangle with area 1000 m2 whose perimeter is as small as possible.
Both the length and width of the rectangle are approximately 31.62 m each.
The Area of a rectangle is calculated by multiplying the length by the width.
A = L x W
We have given that area of rectangle is 1,000 m²
1000 = W× L => W = 1000/L ---(1)
The circumference of rectangle is twice the sum of the dimensions. That is,
P = 2L + 2(1000/L)
Now, it is provided that perimeter is minimum so, we differentiate perimeter with respect to L then put first order derivative equal to zero.
dP/dL = 2 + 2000(-1/L²) = 0
=> 2-2000/L²=0
=>2000/L²=2
=> L²=2000/2
=> L²= 1000
=> L= 31.622
putting value of L in (1) we get , W= 31.622m
Therefore the length and width of the rectangle are both approximately 31.622m .

to find value of the particle moves right ,
we differentiate x(t) , with respect to "x" .
x'(t) = 12×2(a - t)×(-1)
v(t) = -24(a-t) ..... because x'(t) = v(t)
for particle to move right , v(t) > 0 .
-24(a-t) > 0
dividing both sides by "-24" , we get
a - t < 0
a < t

1). If Y Varies inversely as the square of X . If Y= 10 when X=4, Find Y when X=3
2). If Y Varies inversely as X and summing that Y=8 when X=6 find the relationship between X and Y. Also, find Y when X=3
The value of Y = 17.77 when X = 3, and the value of Y = 16 when X = 3
The equation which represents "Y varies inversely as the square of X" can be written as:
Y = k/X² where "k" is a constant.
Substitute the values of X=4 and Y= 10 in the variation equation and solve for k:
⇒ 10 = k/(4)²
⇒ 10 = k/16
⇒ k = 160
The variation equation :
⇒ Y = 160/X²
Substitute the values of X = 3 in the above equation and solve for Y:
⇒ Y = 160/(3)²
⇒ Y = 160/9
⇒ Y = 17.77
Thus, the value of Y = 17.77 when X = 3
The equation which represents "Y Varies inversely as X" can be written as:
Y = k/X where "k" is a constant.
Substitute the values of Y=8 and X=6 in the variation equation and solve for k:
⇒ 8 = k/(6)
⇒ k = 48
The variation equation :
⇒ Y = 48/X
Substitute the values of X = 3 in the above equation and solve for Y:
⇒ Y = 48/(3)
⇒ Y = 16
Thus, the value of Y = 16 when X = 3

How to determine the coordinates of P?In this exercise, line ratio would be used to determine the coordinates of the point on the directed line segment that partitions the segment into a ratio of 5 to 3.
Mathematically, line ratio can be used to determine the coordinates of P and this is modeled by this mathematical expression:
P(x, y) = [(mx₂ + nx₁)/(m + n)], [(my₂ + ny₁)/(m + n)]
Given the following parameters:
Point (x, y)= (-6, 8)Point (x, y) = (-2, -8)m:n = 5:3Substituting the given parameters into the line ratio formula, we have;
P(x, y) = [(mx₂ + nx₁)/(m + n)], [(my₂ + ny₁)/(m + n)]
P(x, y) = [(5(-2) + 3(-6))/(5 + 3)], [(5(-8) + 3(8))/(5 + 3)]
P(x, y) = [(-10 + (-18))/(5 + 3)], [(-40 + 3(8))/(5 + 3)]
P(x, y) = [(-10 - 18)/(8)], [(-40 + 24)/(8)]

Houa works at an electronics store as a salesperson. Houa earns a 4% commission on the total dollar amount of all phone sales she makes, and earns a 5% commission on all computer sales. Houa had $600 more in computer sales than in phone sales and earned a total of $129 in commission. Write a system of equations that could be used to determine the dollar amount of phone sales Houa made and the dollar amount of computer sales she made. Define the variables that you use to write the system.
The system of equations for determining the dollar amount of phone and computer sales are Sc = Sp + 600 and 0.05Sc + 0.04Sp = 1200
How to write a system of equations to determine the dollar amount of phone and computer sales?
A commission is defined as the compensation paid to a person or entity based on the sale of a product. It is calculated on a percentage basis
Given:
Phone sales commission = 4%
Computer sales commission = 5%
Total commission = $129
Let Sc and Sp represent the dollar amount of phone sales and computer sales respectively
If Houa had $600 more in computer sales than in phone sales, the equation can be written as:
Sc = Sp + 600
Since Houa earns a 4% commission on phone sales and a 5% commission on computer sales, and a total commission of $129. Thus, the equation for the commission can be written as:
0.05Sc + 0.04Sp = 1200
Note: 5% = 5/100 = 0.05 and 4% = 4/100 = 0.04
Therefore, the system of equations for determining phone and computer sales are Sc = Sp + 600 and 0.05Sc + 0.04Sp = 1200
