A jeweler has 15 diamond pendants and will display 4 of them from left to right in a glass case. In how many ways can he select and display the 4 pendants?
This is a problem of permutations. In this case, with 15 diamond pendants and selecting 4 at a time, there are 32,760 ways to select and arrange these pendants.
Explanation:This question is about permutations of a set of objects. A permutation is an arrangement of objects in a specific order. The number of permutations of n distinct objects taken r at a time, denoted by P(n, r), can be calculated as: n! / (n-r)! where the '!' symbol represents a factorial, the product of all positive integers less than or equal to the number.
In this case, the jeweler has 15 diamond pendants (n=15) and is selecting and arranging 4 of them (r=4). We can plug these values into the formula to find the number of ways: P(15, 4) = 15! / (15-4)! = 32,760. So, there are 32,760 ways to select and display the 4 pendants.

A square grass field is being paved to convert it to a shopping mall. Each side of the field is 75 meters long. The plan is to reduce the side lengths of the grass field by 5
meters each week. Which function can be used to calculate the area of the grass field, A after T weeks?
(A)=75−(5t)^2
(A)=(75−5t)^2
(A)=75^2 −5
(A)=75^2 -(5t)^2
Answer: second option.
Step-by-step explanation:
The formula for calculate the area of a square is:
[tex]A=s^2[/tex]
Where "s" is the lenght of any side of the square.
You know that the square grass field is 75 meters long and they plan to reduce the side lengths of the grass field by 5 meters each week and the number of weeks is "t", then, the area after "t" weeks will be:
[tex]A=[s_{original}-(s_{eliminated})(number\ of\ week)]^2[/tex]
Substituting you get that the function that can be used to calculate the area of the grass field, "A" after "t" weeks is:
[tex]A=(75-5t)^2[/tex]
This matches with the second option.
The graph shown represents a the rule y=x+1.5
Final answer:
The answer explains the graph of y=x+1.5, a direct relationship with a positive slope, and the graphical representation of the dependence of y on x.
Explanation:
Mathematics: The graph represents the rule y=x+1.5, showing a straight line with a positive slope where the y-intercept is 1.5. As x-values increase, the line gradually rises on the graph.
Direct Relationship: The line's slope remains the same, indicating a direct relationship between x and y.
Slope and Graphical Representation: By connecting points like (1,5), (2,10), (3,7), and (4,14), the dependence of y on x can be graphically illustrated.

Which of the following functions is graphed below.
Answer: Option A
[tex]y=\left \{ {{x^2 +2;\ \ x<1 \atop {-x+2;\ \ x\geq1}} \right.[/tex]
Step-by-step explanation:
In the graph we have a piecewise function composed of a parabola and a line.
The parabola has the vertex in the point (0, 2) and cuts the y-axis in y = 2.
The equation of this parabola is [tex]y = x ^ 2 +2[/tex]
Then we have an equation line[tex] y = -x + 2 [/tex]
Note that the interval in which the parabola is defined is from -∞ to x = 1. Note that the parabola does not include the point x = 1 because it is marked with an empty circle " о ."
(this is [tex]x< 1[/tex])
Then the equation of the line goes from x = 1 to ∞ . In this case, the line includes x = 1 because the point at the end of the line is represented by a full circle .
(this is [tex]x\geq 1[/tex])
Then the function is:
[tex]y=\left \{ {{x^2 +2;\ \ x<1 \atop {-x+2;\ \ x\geq1}} \right.[/tex]
Find the point, M, that divides segment AB into a ratio of 3.1 if A is at (-4,-2) and B is at (4. -10).
Answer:
The coordinates of M are (2,-8)
Step-by-step explanation:
The coordinates of the point that divides the line segment joining
[tex]A(x_1,y_1)[/tex] to [tex]B(x_2,y_2)[/tex] in the ratio m:n is given by:
[tex](\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n})[/tex]
If A is at (-4,-2) and B is at (4. -10) and the ratio is 3:1.
Then
[tex](\frac{3(4)+1(-4)}{3+1},\frac{3(-10)+1(-2)}{3+1})[/tex]
[tex](\frac{8}{4},\frac{-32}{4})[/tex]
The coordinates of M are (2,-8)
To find point M that divides segment AB in a 3:1 ratio, we apply the section formula with m=3 and n=1. The coordinates of point M, given A (-4,-2) and B (4, -10), are found to be (2, -8).
To find the point M that divides the segment AB into a ratio of 3:1, where point A is at (-4,-2) and point B is at (4, -10), we can use the section formula.
This formula allows us to calculate the coordinates of point M that divides AB in the given ratio.
The section formula in two dimensions for a line divided internally in the ratio m:n is given by:
M(x,y) = ((mx2 + nx1)/(m + n), (my2 + ny1)/(m + n))
In this problem, m=3 and n=1, point A (-4,-2), and point B (4, -10). We can substitute these values into the formula:
M(x,y) = ((3*4 + 1*(-4))/(3 + 1), (3*(-10) + 1*(-2))/(3 + 1)) = (8/4, -32/4) = (2, -8)
Therefore, the coordinates of point M are (2, -8).

A box without a top is made from a rectangular piece of cardboard, with dimensions 40 inches by 32 inches, by cutting out square corners with side length x inches.
Which expression represents the volume of the box in terms of x?
A.) (40−2x)(32−2x)x
B.) (40−2x)(32−2x)4x
C.) (40−x)(32−x)x
D.) (2x−40)(2x−32)x
Answer:
The expression is (40 − 2x)(32 − 2x)x ⇒ answe A
Step-by-step explanation:
* Lets study the information of the problem
- The rectangular piece of cardboard has dimensions 40 inches
and 32 inches
- A square of side length x is cutting from each corner
- That means we cut x from each sides of length and width,
x from left corner and x from right corner
∴ The new length = 40 - x - x = 40 -2x
∴ The new width = 32 - x - x = 32 - 2x
* Now when we fold the cardboard to make the box we will stick
the sides of length x together to make the heights of the box
∴ The height of the box = x
- The volume of the box = area of its base × its height
∵ The length of the base is (40 - 2x)
∵ The width of the base is (32 - 2x)
∴ The area of the base = (40 - 2x)(32 - 2x)
∵ The height of the box is x
∴ The volume of the box = (40 - 2x)(32 - 2x)x
* The expression which represent the volume is (40 − 2x)(32 − 2x)x
- The attached picture will help you to understand

A rectangular solid measures 4.9 m by 8.3 cm by 6.8 dm. Express its volume in cubic meters, liters, cubic inches, and cubic feet.
Answer:
Part 1) The volume is 0.276556 m³
Part 2) The volume is 276.556 l
Part 3) The volume is 16,886.94 in³
Part 4) The volume is 9.68 ft³
Step-by-step explanation:
A rectangular solid measures 4.9 m by 8.3 cm by 6.8 dm
Part 1) Express its volume in cubic meters
Convert the measures to meters
Remember that
1 m=100 cm
1 m=10 dm
4.9 m
8.3 cm=8.3/100=0.083 m
6.8 dm=6.8/10=0.68 m
Find the volume
V=4.9*0.083*0.68=0.276556 m³
Part 2) Express its volume in liters
Convert the measures to liters
Remember that
1 m³=1,000 l
we have
V=0.276556 m³
so
Convert to liters
0.276556 m³=0.276556*1,000=276.556 l
Part 3) Express its volume in cubic inches
Convert the measures to inches
we have
4.9 m, 0.083 m, 0.68 m
Remember that
1 m= 39.3701 in
so
4.9 m=4.9*39.3701=192.91 in
0.083 m=0.083*39.3701=3.27 in
0.68 m=0.68*39.3701=26.77 in
Find the volume
V=192.91*3.27*26.77=16,886.94 in³
Part 4) Express its volume in cubic feet
Convert the measures to feet
we have
4.9 m, 0.083 m, 0.68 m
Remember that
1 m=3.28084 ft
so
4.9 m=4.9*3.28084=16.08 ft
0.083 m=0.083*3.28084=0.27 ft
0.68 m=0.68*3.28084=2.23 ft
Find the volume
V=16.08*0.27*2.23=9.68 ft³
If you only have a 1/10 measuring cup and a recipe calls for
4 3/10 cups of flour, how many 1/10 cups would you need to use?
Answer:
Step-by-step explanation:
well let break it down
you have 1/10
you need 4 and 3/10
that can be changed to 43/10 because you need 4 WHOLE or 40/10 (40/10 = 4)
if you can pour 1/10 and you need a total of 43/10, you'd need to use 43 of the 1/10 measuring cups
To measure out 4 3/10 cups of flour using only a 1/10 measuring cup, you would need to fill the 1/10 measuring cup 43 times.
Explanation:To determine how many 1/10 cups are needed to measure out 4 3/10 cups of flour, start by converting the desired amount into tenths.
4 3/10 cups can be thought of as 4 cups plus 3/10 of a cup, which is equivalent to 40/10 cups plus 3/10 cups, giving us 43/10 cups in total.
Since you only have a 1/10 measuring cup, you would need to use this cup a total of 43 times to get 43/10 cups of flour. Therefore, you would need to use the 1/10 measuring cup 43 times to obtain the necessary flour for the recipe.

13) through: (1, 2), slope = 7
A) y = -5x+4 B) y = -5x+7
C) y = 4x - 5 D) y = 7x - 5
Answer: D
Step-by-step explanation:
if the slope is 7, mx + b =y the slope is m. that’s the only one that makes sense. hope this helps!
Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here slope m = 7, thus
y = 7x + c ← is the partial equation
To find c substitute (1, 2) into the partial equation
2 = 7 + c ⇒ c = 2 - 7 = - 5
y = 7x - 5 → D

Step-by-step explanation:
3 3/4 +1 1/2
Need to find the common denominator for 1 1/2
Multiply by 2 for denominator and numerator for 1 1/2
=3 3/4+ 1 2/4
=4 6/4
= 5 2/4
= 5 1/5
Even though there is no multiple choice. I still know the answer.
For this case we must find an expression equivalent to:
[tex]3 \frac {3} {4} +1 \frac {1} {2}[/tex]
We have to:

Why would someone want to factor a polynomial? Provide real-world examples of different questions we can answer or facts we can determine from factoring a polynomial.
-To simplify fractions.
Ex. (2x+10)/2 we factor 2 to simplify so 2(x+5)/2=x+5
Answer:
Step-by-step explanation:
Factoring a polynomial is one important way to find the roots (or x-intercepts) of the polynomial. It's not always the easiest method, particularly when the roots are mixed numbers.
If you take calculus later, you'll see that finding the derivative of a function, setting this derivative = to 0 and solving for the roots is one way in which we can identify the x-value(s) at which we have either a maximum or a minimum.

Answer:
r=9
Step-by-step explanation:
We can use the Pythagorean to solve, since this is a right triangle
The leg lengths are r and 12
The hypotenuse is (r+6)
a^2 + b^2 = c^2
r^2 + 12^2 = (r+6)^2
Foiling out the right hand side
(r+6)(r+6_ = r^2+6r+6r+36
r^2 +144 = r^2 +12r+36
Subtracting r^2 from each side
r^2-r^2 +144 = r^2-r^2 +12r+36
144 = 12r+36
Subtract 36 from each side
144-36 = 12r+36-36
108 = 12r
Divide each side by 12
108/12 = 12r/12
9=r
AC=AB+BC
AC=6+r
AD=12
DC=r
by Pythagorus theorem
AC*2=AD*2+DC*2
(6+r)*2=12*2+r*2
36+12r+r*2=144+r*2
12r+r*2-r*2=144-36
12r=108
r=108/12
r=9
The number of paper clips that crystal has is 42 divided by the number of paper clips that gayle has. If gayle has 11 more paper clips than crystal does, how many paper clips does each have
Answer:
• Gayle: 14
• Crystal: 3
Step-by-step explanation:
Let g represent the number of paperclips Gayle has. Then 42/g is the number Crystal has. The relationship between the two numbers is said to be ...
g - (42/g) = 11
Multiplying by g gives ...
g^2 -42 = 11g
g^2 -11g -42 = 0 . . . . subtract 11 g to put into standard form
To factor this, you are looking for two factors of -42 that sum to -11.
-42 = -42·1 = -21·2 = -14·3 = -7·6
You can see that -14 and 3 sum to -11, so the factoring is ...
(g -14)(g +3) = 0
g = 14 . . . . . . . . . . makes the product zero. (The g=-3 solution is extraneous.)
Gayle has 14 paperclips and Crystal has 3.

The following box-and-whisker plots represent the fuel economy rates (combined city and highway) for the entire fleet of two major car manufacturers. Which of the following statements is not true? The median fuel economy rate of Car Manufacturer A is about 7 miles per gallon higher than the median fuel economy rate of Car Manufacturer B. The range of the middle half of the rates for both manufacturers is about the same. One of the vehicles in Car Manufacturer B's fleet has the lowest fuel economy rate of either manufacturer. Car Manufacturer A's fleet has a larger range of fuel economy rates than Car Manufacturer B's fleet.
Final answer:
Car Manufacturer B does not have the lowest fuel economy rate in the fleet, making this statement false.
Explanation:
Car Manufacturer A:
The median fuel economy rate of Car Manufacturer A is about 7 MPG higher than Car Manufacturer B.
Car Manufacturer A's fleet has a larger range of fuel economy rates than Car Manufacturer B's fleet.
Car Manufacturer B:
The range of the middle half of the rates for both manufacturers is about the same.
One of the vehicles in Car Manufacturer B's fleet has the lowest fuel economy rate of either manufacturer.
From the given box-and-whisker plots, it can be observed that the statement 'One of the vehicles in Car Manufacturer B's fleet has the lowest fuel economy rate of either manufacturer' is not true.

f(x) = x^2 what is g(x)
ANSWER
[tex]g(x) = 9 {x}^{2} [/tex]
EXPLANATION
The given function is:
[tex]f(x) = {x}^{2} [/tex]
The function g(x) is a vertical compression of f(x).
This implies that:
[tex]g(x)=a\bullet f(x)[/tex]
[tex]g(x)=a\bullet {x}^{2} [/tex]
The function g(x) goes through (1,9).
[tex]g(1)=9[/tex]
[tex]a\bullet {(1)}^{2} = 9[/tex]
[tex]a = 9[/tex]
Hence the function is:
[tex]g(x) = 9 {x}^{2} [/tex]
This can be rewritten as:
[tex]g(x) = {(3x)}^{2} [/tex]
The correct choice is A.
Answer: g(x)=(3x)^2

The population of fish in a certain lake follows the logistic growth function , where t is the time in years.
When will the population reach 20,000?
Answer:
46 years
Step-by-step explanation:
We have the logistic growth function [tex]f(t)=\frac{25,000}{1+8.25e^{-0.076t}}[/tex] and we want to find the time when the population will reach 20,000, to do it we just need to replace [tex]f(x)[/tex] with 20,000 and solve for [tex]t[/tex]:
[tex]f(t)=\frac{25,000}{1+8.25e^{-0.076t}}[/tex]
[tex]20,000=\frac{25,000}{1+8.25e^{-0.076t}}[/tex]
Divide both sides by 25,000
[tex]\frac{20,000}{25,000} =\frac{1}{1+8.25e^{-0.076t}}[/tex]
[tex]0.8=\frac{1}{1+8.25e^{-0.076t}}[/tex]
Multiply both sides by [tex]1+8.25e^{-0.076t}[/tex] and divide them by 0.8
[tex]1+8.25e^{-0.076t}=1.25[/tex]
Subtract 1 from both sides
[tex]8.25e^{-0.076t}=0.25[/tex]
Divide both sides by 8.25
[tex]e^{-0.076t}=\frac{0.25}{8.25}[/tex]
[tex]e^{-0.076t}=\frac{1}{33}[/tex]
Take natural logarithm to both sides
[tex]ln(e^{-0.076t})=ln(\frac{1}{33} )[/tex]
[tex]-0.076t=ln(\frac{1}{33} )[/tex]
Divide both sides by -0.076
[tex]t=\frac{ln(\frac{1}{33} )}{-0.076}[/tex]
[tex]t[/tex] ≈ 46
We can conclude that the population will reach 20,000 after 46 years.
