Applying the law of indeces for the fraction with radicals, the value of A=3, b=14 and c=-5
What are radicals?In mathematics, the term radical expressions such that contain a square root. In this question, we have fractions at both sides of the equation with radicals.
To solve this question, let's see some laws below that will help us:
[tex] \sqrt[x]{a} = {a}^{ \frac{1}{x} } [/tex]
[tex] \frac{ {a}^{x} }{ {a}^{y} } = {a}^{x - y} [/tex]
[tex] \frac{1}{ {a}^{x} } = {a}^{ - x} [/tex]
From the given equation; the left hand side will be simplified as follows;
[3^(1/7)]÷[3^(1/2)]=[3^[(2-7)/14]=3^(-5/14)
And the right hand side will be simplified as follows;
1÷[A^(c/b)]=A^-(c/b)
Hence, by comparing both sides of the equation after simplifying the fractional radicals, the value of A is 3, b is 14 and c is -5.

A ball, dropped vertically falls d metres in t seconds
d is directly proportional to the square of t
The ball drops 125 metres in the first 5 seconds
How far does the ball drop in nthe next 9 seconds?
Answers
The distance covered in the next 9 seconds is 405 meters
How to determine the distance coveredThe variation statement is given as
d is directly proportional to the square of t
This means that
d = kt²
Where k represents the constant of variation
Using the parameters in the question, we have
When d = 125, t = 5
Substitute d = 125, t = 5 in d = kt²
This gives
125 = k x 5²
Evaluate
k = 5
So, we have
d = 5t²
After 9 seconds, we have
t = 9
Substitute t = 9 in d = 5t²
Here, we have
d = 5 x 9²
This gives
d = 405
Hence, the distance is 405 meters

Point T is located at (2, 5). Point A is located at (-3, 1.5). Point A is the midpoint of segment TB.
Point B is the midpoint of segment TY. What are the coordinates of point Y?
Answers
Using the midpoint, the coordinates of point Y in the line segment TY is (-18, -9).
How to use midpoint to find coordinates?Point T is located at (2, 5). Point A is located at (-3, 1.5). Point A is the midpoint of segment TB.
Therefore, the mid point formula can be represented as follows:
(xₙ, yₙ) = (x₁ + x₂ / 2, y₁ + y₂ / 2)
Hence, let's find the coordinates of point B.
(-3, 1.5) = (2 + x₂ / 2 , 5 + y₂ / 2)
2 + x₂ / 2 = - 3
cross multiply
2 + x₂ = -6
x₂ = -6 -2
x₂ = - 8
1.5 = 5 + y₂ / 2
3 = 5 + y₂
y₂ = 3 - 5
y₂ = -2
Therefore, the coordinates of B is (-8, -2)
Hence, let's find the coordinate of point Y. The coordinates of point B is the mid point of segment TY.
(-8, -2) = (2 + x₂ / 2 , 5 + y₂ / 2)
(-8, -2) = (2 + x₂ / 2 , 5 + y₂ / 2)
2 + x₂ / 2 = - 8
-16 = 2 + x₂
x₂ = -18
-2 = 5 + y₂ / 2
-4 = 5 + y₂
-4 - 5 = y₂
y₂ = -9
Therefore, the coordinates of y is (-18, -9)

The company uses the formula T = 35.00 + 18.75m to calculate the total charges, where T is the total charges, and m is the number of months of storage. How many months of storage would cost a new customer $260.00?
Answers
Answer:
12 months
Explanation:
Given the function that models the total chacrge of a company as T = 35.00 + 18.75m where;
T is the total charges,
m is the number of months of storage
Given
T = $260.00
we are to find the value of m
Substitute
260 = 35 + 18.75m
18.75m = 260 - 35
18.75m = 225
m = 225/18.75
m = 12
Hence it will take 12 months to cost a new custimer $260.00

2. According to the function given, what is the maximum profit that the company can make?
3. What are the break-even points (the selling prices for which the profit is 0)? Give the answer to the nearest cent.
Answers
Answer:
Below in bold.
Step-by-step explanation:
P(x) = -0.3x² + 75x - 2000
Convert this to vertex form:
p(x) = -0.3(x^2 - 250)^2 - 2000
= -0.3[(x - 125)^2 - 125^2] - 2000
= -0.3[(x - 125)^2 - 15625] - 2000
= -0.3(x - 125)^2 + 4687.5 - 2000
= -0.3(x - 125)^2 + 2687.5
2687.5 is the maximum value of the profit.
1. This corresponds to a selling price of $125 for the stands.
2. Maximum profit is $2687.5.
3. At the breaking points P(x) = 0:
-0.3(x - 125)^2 + 2687.5 = 0
(x - 125)^2 = 2687.5 / -0.3 = 8958.33
x - 125 = +/- sqrt( 8958.33)
x = 125 +/- sqrt( 8958.33)
x = 30.352, 219.648,
So, the breaking even points are $30.35 and $219.65 to nearest cent.

the length and width of a rectangle are consecutive integers. the area of the rectangle is 210 square meters. find the length and width of the rectangle
Answers
The length and the width of the rectangle are 14 and 15 meters, respectively
How to determine the dimension of the rectangle?From the question, the statement is given as
Length and width are consecutive integers
Where
Area = 210 square feet
Represent the dimensions with x and y
Where Length = x and Width = y
And also, we have
y = x + 1
The area of a rectangle is
Area = Length x width
Mathematically, this can be represented as
Area = x * y
So, we have
x * y = 210
Substitute y = x + 1 in x * y = 210
x * (x + 1) = 210
Express 210 as 14 * 15
x * (x + 1) = 14 * 15
This means that
x = 14
Substitute x = 14 in y = x + 1
y = 14 + 1
Evaluate
y = 15
So, we have
x = 14 and y = 15
Hence, the length and the width are 14 and 15 meters

As per the given three coordinate of the triangle, the area of the triangle is 9.5 square units.
Area of triangle:
In the triangle ABC as with vertices or coordinates are A(x1, y1), B(x2, y2), and C(x3, y3), has the area,
Area(ΔABC) = (1/2){x1(y2 − y3) + x2(y3 − y1) + x3(y1 − y2)}
As the area is always positive.
Given,
Here we have the triangle VWX,
And their coordinates are V (-9,-7), W(-4,-5), and X(-6,-2).
Now we have to find the area of the triangle.
To find the area of the triangle, let us consider the coordinates (x1,y1) as v(-9,-7), (x2,y2) as W(-4,-5) and (x3,y3) as X(-6,-2).
Now, we have to apply the values on the formula, in order to get the area of the triangle,
=> A = 1/2 |(-9 [-5-(-2)] + (-4)[-2 - (-7)] + (-6)[-7 - (-5)]|
When we expand the terms, then we get,
=> A = 1/2 |(-9)[-3] + (-4)[5] + (-6)[-2]|
Further simplify the expression will gives you the following,
=> A = 1/2 |27 - 20 + 12|
=> A = 1/2 |19|
Therefore, the area of the triangle is 9.5 square units.
