Answer:

(a) How many are there to select 2 pairs of gloves?

10 ways

(b) How many ways are there to select 4 gloves out of the 10 such that 2 of the 4 make a pair. (a pair consists of any right glove and left glove.)

130 ways

Step-by-step explanation:

We solve the above questions using Combination

Combination = C(n, r) = nCr

= n!/n! ×(n - r)!

(a) How many are there to select 2 pairs of gloves?

We have 5 pairs of gloves. Therefore, the number of ways to select 2 gloves =5C2

= 5!/2! × (5 - 2)!

= 5!/2! × 3!

= 5 × 4 × 3 × 2 × 1/(2 × 1) × (3 × 2 × 1)!

= 10 ways.

(b) How many ways are there to select 4 gloves out of the 10 such that 2 of the 4 make a pair. (a pair consists of any right glove and left glove.)

We are told to select 4 gloves out of the 10 gloves = 10C4

We have 5 pairs, we need to make sure that two out of the selected 4 make a pair = 5 × 2⁴

= 80

Hence,

10C4 - 5C4

= [10!/4! × (10 - 4)!] - 80

= 210 - 80

= 130 ways

Find the prime factors of each term

Answer:

Plato

Step-by-step explanation:

The line segment chosen is HI. Its image is H'I'. The slope of preimage HI is -1.25 and the slope of the image H'I' is -1.25.

The Scale Factor is used to scale shapes in different dimensions. We study different geometrical shapes in geometry, both two-dimensional and three-dimensional. The scale factor is a metric for comparing figures with similar appearances but differing scales or metrics.

The image of a transformation is the shape after the transformation. The preimage of a transformation is the shape before the transformation. The image is scale factor times preimage.

A line passing through the points (x₁, y₁) and (x₂, y₂) will have a slope

m = (y₂ - y₁)/(x₂ - x₁).

We are asked to select a line segment other than LK, which is not a vertical or horizontal line segment, for the scale factor n = 3.

So, we have to select a preimage( other than LK), and its image (3 times the preimage).

So we select the preimage as HI and its image as H'I', as the scale factor between them is n = 3, and HI is not a vertical or horizontal line segment.

Now, we calculate their slopes.

For the preimage HI (slope is m₁):

HI passes through the points (2, 0) and (0, 2.5). Substituting these values in the slope formula, we get

m₁ = (2.5-0)/(0-2) = -2.5/2 = -1.25.

For the image H'I' (slope is m₂):

HI passes through the points (6, 0) and (0, 7.5). Substituting these values in the slope formula, we get

m₂ = (7.5-0)/(0-6) = -7.5/6 = -1.25.

∴ The line segment chosen is HI. Its image is H'I'. The slope of preimage HI is -1.25 and the slope of the image H'I' is -1.25.

NOTE: The slopes of images and preimages are always the same as the image is just an enlarged or diminished form of the preimage.

[tex]\huge\boxed{(2x+8)(x-3)=2x^2+2x-24}[/tex]

Step-by-step explanation:

[tex]\text{Use FOIL:}\ (a+b)(c+d)=ac+ad+bc+bd\\\\(2x+8)(x-3)=(2x)(x)+(2x)(-3)+(8)(x)+(8)(-3)\\\\=2x^2-6x+8x-24\qquad\text{combine like terms}\\\\=2x^2+(-6x+8x)-24\\\\=2x^2+2x-24[/tex]

Answer:

2x^2+2x-24

Step-by-step explanation:

when you see two parentheses, you should first think : FOIL!

you take the First terms in each of the parentheses which is 2x and x and multiply them. (2x^2)

then you take the Outer terms in the parenthesis which is 2x and -3 and multiply them. (-6x)

then you take the Inside terms which is +8 and x and multiply them. (+8x)

lastly, you take the Last terms which is +8 and -3 and multiply them. (-24)

you should get this : 2x^2-6x+8x-24. combine like terms and there's your answer!

i also advise you to write down all your terms until you are familiar with this foil stuff. don't be ashamed if you need to write them down! you'll get the hang of it! :)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given the differential equation dy/dx = 5y/x subject to the condition y = 4 and x = 1. Using the variable separable method of solving differential equation, we will have;

dy/dx = 5y/x

Separate the variables

dy/5y = dx/x

Integrate both sides of the expression

[tex]\frac{1}{5}\int\limits \frac{1}{y} \, dy = \int\limits \frac{dx}{x} \\ \\\frac{1}{5}lny = lnx + C\\\\lny = 5lnx+5C\\[/tex]

using the initial condition y = 4 while x = 1

ln4 = 5ln1 + 5C

ln4 = 0+5C

C = ln4/5

Substituting the value of C back into the expression;

[tex]lny = 5 lnx+5(ln4/5)\\lny = 5lnx+ln4\\lny = lnx^5+ln4\\lny = ln(4x^5)\\y = 4x^5[/tex]

Hence the solution to the differential equation is y = 4x⁵

b) Given 4(du/dt) = u²

du/dt = u²/4

du/ u² = dt/4

u⁻²du = 1/4 dt

integrate both sides of the equation

[tex]\int\limit {u^{-2}} \, du = \int\limits\frac{1}{4} \, dt\\\\\frac{u^{-1}}{-1} = \frac{t}{4} + C\\\\\frac{-1}{u} = \frac{t}{4} + C[/tex]

Imputing the initial condition u(0) = 7 i.e when t = 0, u = 7

[tex]\frac{-1}{7} = \frac{0}{4} + C\\\\\frac{-1}{7} = C\\[/tex]

[tex]\frac{-1}{u} = \frac{t}{4} - \frac{1}{7}[/tex]

Hence the solution to the DE is [tex]\frac{-1}{u} = \frac{t}{4} - \frac{1}{7}[/tex]

This demonstrates the associative property of addition which states that a + (b + c) = (a + b) + c. Basically, it states that it doesn't matter which order you add numbers in, you will always get the same result.

Answer:

a. [tex]Total = 4P[/tex]

b. [tex]Gas = 2P[/tex]

c. [tex]2P - 5[/tex]

d. [tex]P = 20[/tex]

Step-by-step explanation:

Given

[tex]Amount\ received = P[/tex]

[tex]Number\ of\ days = 4[/tex]

[tex]Coffee = \$5[/tex]

[tex]Amount\ Left = \$35[/tex]

Calculating (a); the total amount earned;

[tex]Total = Amount * Days[/tex]

[tex]Total = 4 * P[/tex]

[tex]Total = 4P[/tex]

Calculating (b): Money Spent on Gas

From the question, we understand that 1/2 of his earnings is spent on gas;

Hence;

[tex]Gas = \frac{1}{2} * Total[/tex]

Substitute 4P for Total

[tex]Gas = \frac{1}{2} * 4P[/tex]

[tex]Gas = 2P[/tex]

Calculating (c): Expression for coffee

First, we need to calculate the amount left after buying Gas;

[tex]Amount = Total - Gas[/tex]

[tex]Amount = 4P - 2P[/tex]

[tex]Amount = 2P[/tex]

From this amount, he bough coffee of $5;

Hence; he's left with

[tex]2P - 5[/tex]

Calculating (d): Calculating his daily earnings

After (c) above, he has $35 left

So, we have

[tex]2P - 5 = 35[/tex]

Add 5 to both sides

[tex]2P - 5 + 5= 35 + 5[/tex]

[tex]2P = 40[/tex]

Divide through by 2

[tex]P = 20[/tex]

Hence, his daily earnings is $20

Select each correct answer:

73 • 5 + 4

73 + 5 + 4

73 + 5 • 74

73 • 5 • 74

The answer to this question is  73 • 5 • 74

Explanation:

The symbol • represents multiplication, this implies the numbers 5 and 74 should be multiplied when solving this operation. Moreover, if the expression is simplified the same symbol or a multiplication symbol should be used.

Moreover, the lack of a symbol between these numbers and 73 indicates multiplication. Indeed, in algebra and some fields of mathematics, the multiplication symbol is omitted, and two numbers standing side by side with no symbol indicate the multiplication. Thus, it is correct to place a multiplication symbol between 73 and the other numbers.

Answer:

The average rate of function of f on the given interval is -1.

Step-by-step explanation:

Recall that the average rate of change is simply the slope of the function between two points.

We are given the function:

[tex]f(x)=x^2-4[/tex]

And we want to find its average rate of change on the interval [-4, 3].

Evaluate the two endpoints:

[tex]\displaystyle \begin{aligned} f(-4) & = (-4)^2 - 4 \\ \\ & = 16 - 4 \\ \\ & = 12\end{aligned}[/tex]

Likewise:
[tex]\displaystyle \begin{aligned} f(3) & = (3)^2 - 4 \\ \\ & = 9 - 4 \\ \\ & = 5\end{aligned}[/tex]

Recall that slope is given by:

[tex]\displaystyle m = \frac{\Delta y}{\Delta x}[/tex]

Hence, the average rate of change is:
[tex]\displaystyle\begin{aligned} \text{Avg Rate of Change} & = \frac{(5)-(12)}{(3)-(-4)} \\ \\ &= \frac{-7}{7} \\ \\ & = -1\end{aligned}[/tex]

Answer:

2 hours.

Step-by-step explanation:

From the question given,

Wade can do the work alone in 6 hours.

Rhonda can do the same work in 3 hours.

Next, we shall determine how much work is done by Wade and Rhonda in 1 hour each. This is illustrated below:

If Wade can do the work alone in 6 hours.

Then Wade can do 1/6 of the work in 1 hour.

If Rhonda can do the same work in 3 hours.

Then Rhonda can do 1/3 of the work in 1 hour.

Next, we shall determine the work done by Wade and Rhonda when they work together. This is illustrated below:

Wade's 1 hour work = 1/6

Rhonda's 1 hour work = 1/3

Therefore, work done by Wade and Rhonda together in 1 hour = 1/6 + 1/3 = 3/6 = 1/2

Since they completed 1/2 of the work in 1 hour, it means they will complete the work in 2 hours.

Answer:  (a) 720°,  (b)  120°

Step-by-step explanation:

A hexagon is a polygon with six sides.

Formula for finding the interior angle of a polygon = ( 2n - 4 )complementary

                                                                                    = ( 2n - 4 ) 90

complimentary angle is 90°  or

                                                                                     = ( n - 2 )supplementary

supplementary angle is 180° . Now solving the question now since n = 6

we now put it in any of the formula above

       ( 2 x 6 - 4 ) x 90  =  ( 12 - 4 ) x 90

                                   =   8 x 90

                                   = 720°     or

     ( 6 - 2 ) x 180        =  4 x 180

                                  = 720°.

The second part of the question, each size of the interior angle

                                  = ⁷²⁰/₆

                                  = 120°
