x=swrt(64)=8

By applying the Pythagorean Theorem, we find out that the width of Blake's living room is 8 meters. This theorem helps to calculate the unknown side of a right triangle when the other two sides are known.

To answer this question, we can apply the Pythagorean Theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, the diagonal across the rectangular room is the hypotenuse of a right triangle, with the length and width of the room as the remaining sides.

Given that the length of the room is 6 meters and the hypotenuse is 10 meters, we can substitute these values into the formula of the Pythagorean Theorem:

Width² = Hypotenuse² - Length²

Substituting the known values gives:

Width² = 10² - 6²

Width² = 100 - 36

Width² = 64

Then, taking the square root of both sides:

Width = 8 meters

Therefore, the width of Blake's living room is 8 meters.

Answer:

The average rate of change for this quadratic function is -2.

Step-by-step explanation:

In this question, we have f(x) = y = x^{2} + 4x + 5.

Given a function y, the average rate of change S of y=f(x) in an interval  [x_s, x_f] will be given by the following equation:

S = \frac{f(x_{f}) - f(x_s)}{x_f - x_s}

So, in  your problem, f(x) = x^{2} + 4x + 5, x_{f} = -2 and x_{s} = -4.

Applying these informations to the equation S above, we have:

S = \frac{f(-2) - f(-4)}{-2-(-4)}

Where

f(-2) = (-2)^{2} + 4(-2) +5 = 4-8+5 = 9-8 = 1

f(-4) = (-4)^{2} + 4(-4) +5 = 16-16+5 = 5

So, the average rate of change S will be

S = \frac{1-5}{2} = -4

Step-by-step explanation:

a.  here you are to multiply the two functions together:

[tex](3x-1)(2x^{2} )=6x^{3}-2x^{2}[/tex]

b.  here you are to subtract g from f:

[tex](3x-1)-(2x^{2})=-2x^{2}+3x-1[/tex]

c.  here you are to compose g into f.  In other words, pick up the whole g function and plug it into f wherever you see an x:

[tex]3(2x^{2} )-1=6x^{2} -1[/tex]

d.  here you are compose f into g.  In other words, pick up the whole f function and plug it into g wherever you see an x:

[tex]2(3x-1)^2[/tex]

You now have to FOIL out the (3x-1) like so:

[tex]2[(3x-1)(3x-1)][/tex]

which gives you

Given:

Problem-solving:

Let us prepare the leading terms, constant terms, and the coefficients of the polynomial are being asked.

[tex]\boxed{ \ 7x^5 + bx^4 + cx^3 + dx^2 + ex + 6 \ }[/tex]

Now we make the first polynomial, for example:

Thus, the result is [tex]\boxed{\boxed{ \ 7x^5 + 3x^4 - 2x^3 + 2x^2 - 5x + 6 \ }}[/tex]

Then we make the second polynomial as an alternative. For example:

Thus, the polynomial is [tex]\boxed{\boxed{ \ 7x^5 - 6x^4 + 4x^2 + 6 \ }}[/tex]

Of course, you can form another polynomial using the procedure above. Try to vary the coefficients.

Notes:

Let us rephrase the following definitions.

For example, consider the polynomial [tex]\boxed{ \ 2x^4 - 3x^2 - 4x - 5 \ }[/tex]

A polynomial is said to be in standard form if the terms are written in descending order of degree. For example:

Keywords: a polynomial of the 5th degree, a leading coefficient of 7, a constant term of 6, a monomial, terms, the leading coefficient, constant, in a standard form, rational function, whole number power, integer

A polynomial of the 5th degree with a leading coefficient of 7 and a constant term of 6 could take the form of 'f(x) = 7x^5 + 6'. The other coefficients (b, c, d, e) can be any real numbers, but for simplicity, they can be set to zero in this instance.

The student's question relates to constructing a polynomial of the 5th degree with specific characteristics in the field of Mathematics, specifically in algebra. One can present such a polynomial with the general form:

f(x) = ax^5 + bx^4 + cx^3 + dx^2 + ex + f

Where the leading coefficient a is 7 and the constant term f is 6. In this case, since the only information provided is the leading coefficient and the constant term, and not any constraints on the other coefficients (b, c, d, e), they can be any real numbers, including zero. Thus, one example of a polynomial fitting these constraints is:

f(x) = 7x^5 + 0x^4 + 0x^3 + 0x^2 + 0x + 6

To simplify the algebra and make calculations easier, one can eliminate terms wherever possible, which in this example has been executed by setting the coefficients of x^4, x^3, x^2, and x to zero. After forming any polynomial, it is also important to check the answer to ensure that it matches the given criteria, which in this case it does.

The expected gain or loss for this store is a gain of $79,750.

Gain is defined as the profit occurred by a store or a shopkeeper when an item is sold at a higher price than it was originally bought.

Loss is defined as the money lost by a store or a shopkeeper when an item is sold at a lower price than it was originally bought.

Both gain or loss is calculated by the formula -

Cost Price (CP) - Selling price (SP)

It is given that the company estimates that there is an 80% chance the store will have a profit of $100,000, a 10% chance of the store will break even, and a 10% chance of the store will lose $2,500.

Calculating the net gain or loss or the company -

= (80% * $100,000) + (10% * $0) - (10% * $2,500)

= (80/100 * $100,000) - (10/100 * $2,500)

= $80,000 - $250

= $79,750

Thus the net gain involved in the business by the company is $79,750 .

Therefore, the expected gain or loss for this store is a gain of $79,750.

Step-by-step explanation:

Using Pascal's triangle, the expansion, although EXTREMELY lengthy, will help you find the 7th term.  I am going to type out the expansion only up til the 7th term (although there are actually 10 terms because we are raised to the power of 9).  If you would like to learn how to use Pascal's Triangle for binomial expansion, you will need to visit a good website that explains it because it's just too difficult to do it via this website.

The expasion is as follows (up to the 7th term):

[tex]1(3c)^{9} +9(3c)^{8}(2d)^{1} +36(3c)^{7}(2d)^{2} +84(3c)^6(2d)^3+126(3c)^5(2d)^4+126(3c)^4(2d)^5+84(3c)^3(2d)^6[/tex]

That last term is the 7th term.  You find out its value by multiplying all the numbers together and adding on the c^3d^6.  Again those come from Pascal's triangle, and it's one of the coolest math things ever.  I encourage you to take the time to explore how it works.

Answer:

  (d)  $1120.70

Step-by-step explanation:

You want the total of deposited checks as shown on the deposit slip.

The total value of checks is shown on the line "Subtotal." This is amount of the deposited checks. The same deposit slip shows a withdrawal of $80 cash, so the net deposit is $80 less than that subtotal.

Vera deposited $1120.70 in checks, choice D.

The correct total amount of all checks Vera deposited is $664.30, and the deposit ticket reflects a subtotal of $1040.70, which includes both checks and cash. Therefore, option (b) $664.30 is the accurate representation of the total amount of all checks.

To determine the total amount of all checks Vera deposited, we need to add the amounts of the individual checks listed on the deposit ticket.

1. Check #184: $138.09

2. Check #308: $312.15

3. Check #298: $214.14

Adding these amounts: $138.09 + $312.15 + $214.14 = $664.38

Therefore, the correct answer is option (b) $664.30. This represents the total amount of all checks Vera deposited. The deposit ticket indicates the subtotal of checks as $1120.70, but this includes the cash amount received as well. To find the total amount of all checks, we subtract the cash amount received, which is $80.00, from the subtotal: $1120.70 - $80.00 = $1040.70.

Answer: 144°

Step-by-step explanation:

It is a regular pentagon which means all five sides are the same length. This also means that the angle between any two adjacent vertices is the same. So to find the angle between two adjacent vertices we take 360° and divide it by 5 which equals 72°. But A and D are not adjacent to each other, they have E in the middle (it also has B and C in the middle on the other side, but that's the bigger angle, and we usually label angles through their smaller angle. ex: a 30° angle is 30° if you look at it on the smaller angle (∠ ← here), but if you look at the bigger side of the angle (here →∠) it is 330°, yet we still call it a 30° angle). So, between A and D are two equal angles A to E, and E to D. So we multiply 72° by 2 which equals 144°.

So the answer is 144°.

A. 2 to 5

Step-by-step explanation:

x is being multiplied by 2.

y is being multiplied by 5.

Although there is an infinite amount of ratios we can use when we know the values,we don't have that right now, so we have to stick to 2 to 5, which is our answer.

Answer:

B.The area of the base of the pyramid is 24cm^2.

C.A rectangular prism with the dimensions of 9 cm by 4 cm by 6 cm will have 3 times volume of this pyramid.

E.The volume of this pyramid is 72cm3.

Step-by-step explanation:

Area of base of the pyramid = l × w = 4 × 6 = 24 cm^2

Volume of rectangular pyramid = (l × w × h)/3 = (4 × 6 × 9)/3 = 72 cm^3

Volume of rectangular prism = w × h × l = 9 × 4 × 6 = 216 cm^3

So according to these calculations, the correct answer options are:

B.The area of the base of the pyramid is 24cm^2.

C.A rectangular prism with the dimensions of 9 cm by 4 cm by 6 cm will have 3 times volume of this pyramid.

E.The volume of this pyramid is 72cm3.

Final answer:

The true statements about the rectangular pyramid are B, C, and E.

The base area is 24 cm² (Statement B), the volume of the pyramid is 72 cm³ (Statement E), and the volume of a similarly dimensioned rectangular prism is three times that of the pyramid (Statement C).

Explanation:

To determine which statements are true about the rectangular pyramid with given dimensions, we need to calculate the base area and the volume of both the pyramid and the rectangular prism and compare them.

The base area of the pyramid, denoted as B, is the area of the rectangle formed by the base's dimensions.

Therefore, B = length x width = 4 cm x 6 cm = 24 cm².

Thus, statement B is true.

For the volume of the pyramid (V), we use the formula V = (1/3) x B x height.

Plugging the values, we get V = (1/3) x 24 cm² x 9 cm, which equals 72 cm³.

So, statement E is true.

The volume of a rectangular prism with the same height and base dimensions is volume of the prism = length x width x height = 4 cm x 6 cm x 9 cm = 216 cm³.

Since the volume of the prism is three times the volume of the pyramid, statement C is true.

Statements A, D, and F are not true based on the above calculations and explanations.

Step-by-step explanation:

1) According to the given statement Bradley dropped the ball from a roof 16 feet high.Each time the ball hits the ground, it bounces3/5 the previous height

Therefore,

First bounce = 16*3/5 = 9.6

Second bounce = 9.6 *3/5 = 5.76

Third bounce =  5.76*3/5=3.456

Fourth bounce = 3.456*3/5=2.0736

The height the ball will bounce after hitting the ground the fourth time = 2.0736ft....

2) The 2002 Denali earthquake in Alaska had a Richter scale magnitude of 6.7.

Denali earthquake = 6.7 * 70 =469

The answer is R0, 90° and (x , y) → (-y , x) ⇒1st and 4th

Step-by-step explanation:

* Lets revise the rotation rules

- If point (x , y) rotated about the origin by angle 90° anti-clock wise

 (+90° or -270°)

∴ Its image is (-y , x)

- If point (x , y) rotated about the origin by angle 90° clock wise

 (-90° or +270°)

∴ Its image is (y , -x)

- If point (x , y) rotated about the origin by angle 180°

 (+180° or -180°)

∴ Its image is (-x , -y)

* There is no difference between rotating 180° clockwise or  

  anti-clockwise around the origin

* Lets solve the problem

∵ Δ XYZ has vertices⇒ X (0 , 0) , Y (0 , -2) , Z (-2 , -2)

∵ Δ X'Y'Z' has vertices X' (0 , 0) , Y' (2 , 0) , Z' (2 , -2)

* From them

# Y = (0 , -2) and Y' = (2 , 0), that means the image is (-y , x)

# Z = (-2 , -2) and Z' = (2 , -2), that means the image is (-y , x)

∴ The rotation is around the origin with angle 90° anti-clockwise

V.I.N: Anti-clock wise means positive angle , clockwise means

negative angle (90° means anti-clockwise , -90° means clockwise)

∴ The answer is: R0, 90° and (x , y) → (-y , x)
