11) Given that the points (-1, 6), (3, 6), (3, 1), and (-1, 1) are vertices of a rectangle, how much shorter is the width than the length?
A) -5 units
B) -4 units
C) -3 units
D) -2 units
E) -1 unit
-1 unit is the correct answer.
By calculating the distances between the horizontal and vertical points of the rectangle, we find that the width is 1 unit shorter than the length.
Explanation:To determine how much shorter the width is than the length of the rectangle formed by the points (-1, 6), (3, 6), (3, 1), and (-1, 1), we can calculate the distances between the points.
The length can be measured either between the first and second point or the third and fourth, as they have the same y-value but different x-value, which is a horizontal distance on the graph.
The width can be measured between the first and fourth point or the second and third point since they share the same x-value but differ in y-values, constituting a vertical measurement.
Length is distance between (-1, 6) and (3, 6) or (3, 1) and (-1, 1) which is |3 - (-1)| = 4 units. Width is the distance between (-1, 6) and (-1, 1) or (3, 6) and (3, 1) which is |6 - 1| = 5 units.
The width is longer than the length, so to find out how much shorter the width is compared to the length, we subtract the two: 4 - 5 = -1 unit.

Which shows the rational expression written using the least common denominator? X+1/4x^2+x+1/x^2
The rational expression [tex]\dfrac{x + 1}{4x^2} + \dfrac{x + 1}{x^2}[/tex] using the least common denominator is [tex]\dfrac{5 + 5x}{4x^2}[/tex]
How to express the rational expression using the least common denominator?
From the question, we have the following parameters that can be used in our computation:
[tex]\dfrac{x + 1}{4x^2} + \dfrac{x + 1}{x^2}[/tex]
Take the LCM of the expression
So, we have
[tex]\dfrac{x + 1}{4x^2} + \dfrac{x + 1}{x^2} = \dfrac{x + 1 + 4(x + 1)}{4x^2}[/tex]
Expand the bracket
[tex]\dfrac{x + 1}{4x^2} + \dfrac{x + 1}{x^2} = \dfrac{x + 1 + 4x + 4}{4x^2}[/tex]
So, we have
[tex]\dfrac{x + 1}{4x^2} + \dfrac{x + 1}{x^2} = \dfrac{5 + 5x}{4x^2}[/tex]
Hence, the rational expression using the least common denominator is [tex]\dfrac{x + 1}{4x^2} + \dfrac{x + 1}{x^2} = \dfrac{5 + 5x}{4x^2}[/tex]
you invested your allowance of $270 which gets 15% compounded annually for 3 years. How much will you have in 3 years
____________________________________________________
Answer:
Your answer would be $410.64
____________________________________________________
Step-by-step explanation:
In order to find the amount of money you would have in 3 years, you would have to multiply the principal each time by 15% 3 times.
We would start with our starting allowance, and multiply that by 1.15, and so on:
270 × 1.15 = 310.50
310 × 1.15 = 357.075
357.073 × 1.15 = 410.636
Since we have three numbers after the decimal, we would want to round up to the nearest hundredth because that's how the value of money works. Cents only go up to the hundredths place.
We would round the 6 to the three, in which would make the three turn into 4. When you round, the numbers 1-4 would keep the number before it the same, 5-9 would make the number before it go up by 1.
410.636 would turn into 410.64.
You would have $410.64 dollars in three years.
____________________________________________________
With a principal of $270 and an annual compound interest rate of 15%, your investment will grow to approximately $410.64 in 3 years.
To determine how much your investment of $270 will grow in 3 years with an annual compound interest rate of 15%, you can use the compound interest formula:
A = P(1 + r/n)ⁿᵗ
Where:
A = the future value of the investment/loan, including interestP = the principal investment amount ($270)r = the annual interest rate (decimal) (0.15)n = the number of times that interest is compounded per year (1, since interest is compounded annually)t = the number of years the money is invested or borrowed for (3)Now plug in the values:
A = 270(1 + 0.15/1)¹*³Simplify inside the parenthesis:
A = 270(1 + 0.15)³Then:
A = 270(1.15)³Calculate the exponent:
A = 270 * 1.520875Finally, multiply:
A ≈ 410.64After 3 years, your investment will grow to approximately $410.64.
This demonstrates the power of compound interest, which is an important concept to understand when investing.

if p= (-2,7) find: Rx-axis(P)
Answer:
P(-2,7)
P'(-2,-7), ANSWER
reflection across the x-axis rule:
(×,y) ===> (x,-y)
Easy way to do this is draw the point on graph paper and count the same units above/below the x-axis. This example you are 7 units above the x-axis so you would count 7 units below the x-axis giving you the point.
Reflection of a point across an axis involves flipping the sign of the coordinate for that axis. So the reflection of point P(-2,7) on the x-axis is P'(-2,-7).
Explanation:The concept described in your question refers to the reflection of a point across the x-axis. Given a point P(-2,7), the reflection of this point across the x-axis, denoted as Rx-axis(P), reverses the sign of the y-coordinate. This happens because a reflection is a transformation that flips a figure across an axis of reflection.
So, if we consider P(-2,7) to reflect about the x-axis, we just switch the sign of y-coordinate. Therefore reflection of point P(-2,7) about x-axis will be P'(-2,-7).

Amanda says that a human fingernails has a thickness of about 4.2 x 10^-4 meter. Justin says that a human fingernails has a thickness of about 0.42 millimeters .
What is the width in meters written in standard notation?
Do Justin’s and Amanda’s measurements agree? Explain .
Explain why Justin’s estimate of the thickness of a human fingernail is made appropriate than Amanda’s estimate.
Answer:
See below
Step-by-step explanation:
1. Standard notation
4.2 × 10⁻⁴ m
A negative exponent indicates
A number between 0 and 1. That the decimal point is shifted that number of places to the left.4.2 × 10⁻⁴ tells you that the decimal number is 4.2, with the decimal point moved four places to the left.
The number becomes 0.000 42 .
2. Metres to millimetres
[tex]4.2 \times 10^{-4}\text{ m} \times \dfrac{10^{3}\text{ mm}}{\text{1 m}} = 4.2\times 10^{-1}\text{ mm = 0.42 mm}}[/tex]
3. Measurements agree?
Yes, because both measurements are the same as 0.42 m.
4. More appropriate measurement
Most measurements should be expressed as a number between 0.1 and 1000, because most people aren’t particularly good at visualizing larger or smaller numbers.
Justin's measurement of 0.42 mm is more appropriate than Amanda's measurement of 4.2 × 10⁻⁴ m.

A marketing firm tracks data on grocery store visits. In one study, it finds that the probability that a shopper buys bread during a visit to the grocery store is 0.60, and the probability that a shopper buys cheese is 0.25. Event A A shopper buys bread. Event B- A shopper buys cheese. A and B are independent events if____.
Answer: A and B are independent events if P(A∩B)=P(A).P(B)=0.15.
Step-by-step explanation:
Let A be the event that a shopper buys bread.
Let B be the event that a shopper buys cheese.
So, P(A∪B)=100
Probability that a shopper buys bread during a visit to the grocery store =n 0.60
P(A) = 0.60
Similarly, Probability that a shopper buys bread = 0.25
P(B) = 0.25
Since A and B are independent then,
[tex]P(A\cap B)=P(A).P(B)=0.60\times 0.25=0.15[/tex]
So, A and B are independent events if P(A∩B)=P(A).P(B)=0.15.
A textbook has a length of 6 inches, a height of y inches, and a width of x inches. If the length of the diagonal of the front cover is 8 inches and the length of the diagonal of the width is 7 inches, find the values of x and y.
Answer:
x = 2√7, y = √21
Step-by-step explanation:
The textbook has right angles, so we can use Pythagorean theorem to find the missing lengths.
For the triangle on top of the textbook:
c² = a² + b²
8² = 6² + x²
64 = 36 + x²
28 = x²
x = √28
x = 2√7
For the triangle on the side of the textbook:
c² = a² + b²
7² = x² + y²
49 = 28 + y²
21 = y²
y = √21

B. left parenthesis 3 comma 7 right parenthesis
C. left parenthesis negative 2 comma 7 right parenthesis
D. left parenthesis 5 comma 2 right parenthesis
Answer:
A. left parenthesis 3 comma 2 right parenthesis
Step-by-step explanation:
The point A is at (-2, 2) which is 2 units to the left and 2 units up from zero
We want 5 horizontal units from A. Horizontal means left and right
If we go 5 units to the right

If we go 5 units to the left
(-2 -5 , 2) = (-7,2)
a line parallel to a triangle’s side splits line AB into lengths of x-6 and x. the other side, line AC, is split into lengths of x+6 and x+20. what is the length of AC ?
Answer:
56
Step-by-step explanation:
Let's say that D is the point where AB is split, so AD = x-6 and DB = x.
And let's say that E is the point where AC is split, so AE = x+6 and EC = x+20.
Triangle ADE is similar to triangle ABC. Therefore:
(x-6) / (x-6 + x) = (x+6) / (x+6 + x+20)
Solving:
(x-6) / (2x-6) = (x+6) / (2x+26)
(x-6) (2x+26) = (x+6) (2x-6)
2x² + 26x - 12x - 156 = 2x² - 6x + 12x - 36
2x² + 14x - 156 = 2x² + 6x - 36
14x - 156 = 6x - 36
8x = 120
x = 15
So the length of AC is:
AC = x+6 + x+20
AC = 2x + 26
AC = 2(15) + 26
AC = 56

A box of candy is shaped like a triangular pyramid the volume of the candy box measures 120 in squared 3 the area of the base of the candy box is 18 in squared 2 what is the height of the candy box
When using the formula for the volume of a pyramid, substituting the given values of base area and volume results in a candy box height calculation of 20 inches.
Explanation:The question asks about the height of a box of candy shaped like a triangular pyramid, given the volume and the area of the base. The volume of a pyramid is given by the formula V = 1/3 * Base Area * height. In this case, the box volume equals 120 in³, and the base area equals 18 in². We can use these values to solve for the height.
By rearrangement of the formula, height = V / (1/3 * Base Area). If we plug in the values, height = 120 in³ / (1/3 * 18 in²) = 20in. Therefore, the height of the candy box is 20 inches.

The height of the candy box is 20 inches.
Explanation:To find the height of the candy box, we need to use the formula for the volume of a triangular pyramid, which is V = (1/3) * A * h, where V is the volume, A is the area of the base, and h is the height.
We are given that the volume is 120 in³ and the area of the base is 18 in², so we can plug these values into the formula and solve for h.
120 = (1/3) * 18 * h
Simplifying the equation, we get:
360 = 18h
Dividing both sides by 18, we find that h = 20.
Therefore, the height of the candy box is 20 inches.

What is the parent function of the following graph?
X^4 because it has 4 zeroes ( the graph crosses the x axis 4 times
The parent function of the given graph is:
Option: C
[tex]F(x)=x^4[/tex]
Step-by-step explanation:Since, the graph of the function has four real zeros this means that the parent function must be a function of degree four.
Also, we know that if the degree of the parent function would be odd then the end behavior of the graph ( i.e. the behavior of the graph when x tends to infinity and when x tends to minus infinity ) must be in opposite direction.
But here the graph is in the same direction.
Hence, the degree of the function is four i.e. even.
From the given choice the choice that best matches the condition is:

from f(x) = x - 9, we are told that the function is shifted 2 units up, this is a vertical shift. so we add 2 to -9
-9 + 2 = -7
we now have f(x) = x - 7
next we are told that the function is shifted 3 units to the left. this is a horizontal shift. a horizontal shift looks similar to this:
f(x) = (x ± b)
if a function is shifted to the left, we would use an addition sign. if it was going to the right, we would use a subtraction sign
the function looks like the following when we apply the above knowledge
f(x) = (x + 3) - 7 this would be our new function
The new function will be f(x) = (x + 3) - 9 + 2.
Explanation:The function given is f(x) = x - 9. When this function is shifted 2 units up and 3 units to the left, the new function is obtained by transforming the original function accordingly.
Shifting up by 2 units means adding 2 to the function, and shifting 3 units to the left means substituting x+3 for x.
Thus, the new function, after applying the transformations, is:
f(x) = (x + 3) - 9 + 2
Simplifying the above transformation, we get:
f(x) = x - 4
