Properties of Real Numbers ...

Step-by-step explanation:

Commutative Property of Multiplication (Numbers) 2 • 10 = 10 • 2

Associative Property of Addition (Numbers) 5 + (6 + 7) = (5 + 6) + 7

Associative Property of Multiplication (Numbers) 6 • (3 • 2) = (6 • 3) • 2

Additive Identity (Numbers) 6 + 0 = 6

The equation demonstrates the Associative Property of Addition, stating that the grouping of numbers being added does not affect the sum.

The property shown in the equation 3 + (5 + 7) = (3 + 5) + 7 is the Associative Property of Addition. According to this property, the grouping of numbers being added does not affect the sum. In other words, when adding three or more numbers, it doesn't matter how they are grouped in parentheses.

In this specific equation, we are adding 5 and 7 first, which gives us 12. Then, adding 3 to 12 gives us a sum of 15. On the other side of the equation, we first add 3 and 5 to get 8, and then add 8 to 7 to get the same sum of 15.

Answer:

The radius of the base of the cone is 2 units

The slant height of the cone is 4 units

The height of the cone is 2√3 units

The volume of the cone is [tex]\frac{8\sqrt{3}\pi}{3}[/tex]units³

Step-by-step explanation:

* Lets revise the total surface area and the lateral area of a cone

- The lateral area of cone = π r l , where r is the radius of the base

  and l is the slant height of the cone

- The surface area of the cone = π r l + π r², where π r l is the lateral

  area and π r² is the base area

- The cone has three dimensions radius (r) , height (h) , slant height (l)

- r , h , l formed right triangle, r , h are its legs and l is its hypotenuse,

 then l² = r² + h²

- The volume of the con = [tex]\frac{1}{3}[/tex] (π r² h)

* Now lets solve the problem

- We will use the total area to find the radius of the base

∵ TA = 12π

∵ TA = LA + πr²

∵ LA = 8π

- Substitute the value of the lateral area in the total area

∴ 12π = 8π + π r² ⇒ subtract 8π from both sides

∴ 12π - 8π = π r²

∴ 4π = π r² ⇒ divide both sides by π

∴ r² = 4 ⇒ take square root for both sides

∴ r = 2

* The radius of the base of the cone is 2 units

- We will use the lateral area to find the slant height

∵ LA = π r l

∵ LA = 8π

∵ r = 2

∴ π (2) l = 8π ⇒ divide both sides by π

∴ 2 l = 8 ⇒ divide both sides by 2

∴ l = 4

* The slant height of the cone is 4 units

- Use the rule l² = r² + h² to find the height of the cone

∵ r = 2 and l = 4

∵ l² = r² + h²

∴ (4)² = (2)² + h²

∴ 16 = 4 + h² ⇒ subtract 4 from both sides

∴ 12 = h² ⇒ take square root for both sides

∴ h = √12 = 2√3

* The height of the cone is 2√3 units

∵ The volume of the con = [tex]\frac{1}{3}[/tex] (π r² h)

∵ r = 2 and h = 2√3

∴ V = [tex]\frac{1}{3}[/tex] (π × 2² × 2√3) = [tex]\frac{1}{3}[/tex] (π × 4 × 2√3) = [tex]\frac{1}{3}[/tex] (π × 8√3)

∴ V = [tex]\frac{8\sqrt{3}\pi}{3}[/tex]

* The volume of the cone is [tex]\frac{8\sqrt{3}\pi}{3}[/tex]units³

Answer:

Step-by-step explanation:

We need to find the value of log4(768).

768 can be written as 3*256

which further can be simplified to 3*4^4

so using the log property log(AB)=log A+ log B

we can write

log4(768) = log4(3)+log4(4^4)

                 =0.7925+4log4(4)

                 =0.7925+4

                  =4.7925

Answer:

150

Step-by-step explanation:

Given that;

Company A offers;

Salary= $ 17000

commission= $100 per tv set

Company B offers;

Salary= $29000

Commission = $ 20 per tv set

Let the number of tv set sold to be= x

To solve this problem, the amount obtained after selling for A option should be equal to B option

Form equations

[tex]17000 +100 x = 29000 + 20x\\\\\\100x-20x= 29000-17000\\\\\\80x=12000\\\\\\x=12000/80 = 150[/tex]

The number of televisions sold for the options to be equal = 150

Answer:

Amara needs to sell 150 televisions to make both options earnings equal.

Step-by-step explanation:

Let the number of television sold be = x

For company A:

Salary is $17,000 plus a $100 commission for each television she sells.

Equation becomes:

[tex]f(x)=17000+100x[/tex]

For company B :

Salary is $29,000 plus a $20 commission for each television she sells.

Equation becomes:

[tex]f(x)=29000+20x[/tex]

So, to calculate how many televisions would Amara need to sell for the options to be equal, we will equal both the equations.

[tex]17000+100x=29000+20x[/tex]

=> [tex]100x-20x=29000-17000[/tex]

=> [tex]80x=12000[/tex]

x = 150

So, Amara needs to sell 150 televisions to make both options earnings equal.

We can check this :

[tex]17000+100(150)=29000+20(150)[/tex]

=> [tex]17000+15000=29000+3000[/tex]

=> [tex]32000=32000[/tex]

[tex]y=a(x-p)(x-q)[/tex]

[tex]\text{x-intercepts:}\ p\ \text{and}\ q\\\\\text{y-intercept}:\ a(-p)(-q)[/tex]

We have the equation:

[tex]y=2x^2-9x-5=(2x+1)(x-5)[/tex]

[tex]2x+1=2\left(x+\dfrac{1}{2}\right)\to y=2\left(x+\dfrac{1}{2}\right)(x-5)[/tex]

Therefore

[tex]a=2\\\\x-intercepts:\ p=-\dfrac{1}{2}\ \text{and}\ q=5\\\\\text{y-intercept:}\ (2)\left(-\dfrac{1}{2}\right)(5)=-5[/tex]

The x-intercepts are -1/2 and 5, and the y-intercept is -5.

The factored form of a quadratic equation is y=(2x+1)(x-5). To find the x-intercepts, we set y=0 and solve for x. Therefore:

The y-intercept is found by setting x=0 and solving for y. So:

Therefore, the correct statement is:

The x-intercepts are -1/2 and 5, and the y-intercept is -5.

d = dⁿ - dⁿ-¹

The common difference of the given sequence will be 5, i.e. option D.

Arithmetic progression is the sequence of numbers in order, in which the difference between any two consecutive numbers is a constant value. The common difference is the value between each successive number in an arithmetic sequence

i.e. Common difference (d) = Successive term - Previous term

We have,

0, 5, 10, 15, 20, . . .

Here,

a₁ = 0

a₂ = 5

a₃ = 10

a₄ = 15

a₅ = 20

Now,

Find the common difference,

i.e.

Common difference (d) = a₂ - a₁ = 5 - 0 = 5,

Now,

Common difference (d) = a₃ - a₂ = 10 - 5 = 5

Now,

Common difference (d) = a₄ - a₃ = 15 - 10 = 5

Now,

Common difference (d) = a₅ - a₄ = 20 - 15 = 5

Now,

The Common difference is same for all i.e. 5.

Final answer:

The discriminant of the equation 4x^2+16x+16=0 is 0, indicating that there is one real, repeated root.

Explanation:

To find the discriminant and the number of real roots for the equation 4x^2+16x+16=0, we first recognize it as a quadratic equation of the form ax^2+bx+c=0. The discriminant of a quadratic equation is given by the formula b^2-4ac. In our equation, a=4, b=16, and c=16. Substituting these values into the formula gives us 16^2 - 4(4)(16), which simplifies to 256 - 256, yielding a discriminant of 0. A discriminant of 0 indicates that there is exactly one real root, which is also a repeated or double root.

ANSWER

5.2387 and 5.2437

EXPLANATION

To round a decimal to the nearest hundredth means we should round to two decimal places.

To round to two decimal places we consider the third decimal place.

When we round 5.2387 to the nearest hundredth, we obtain 5.24 because the third decimal place is greater than or equal to 5 so we round up.

When we round 5.2437 to the nearest hundredth, we get 5.24 because the third decimal place less than 5 so we round off.

In fact there are infinitely many decimals that will round to 5.24 when rounding to the nearest hundredth.

Answer:

8 inches

Step-by-step explanation:

To find the area of a triangle, we use the formula

A = 1/2 bh where b is the length of the base and h is the height

A = 24 and b = 6

24 = 1/2 (6) * h

24 =3h

Divide each side by 3

24/3 = 3h/3

8 =h

The height is 8 inches

The answer is:

The height of the triangle is equal to 8 inches.

[tex]height=8in[/tex]

To find the height of the triangle, we need to use the formula to calculate the area of a triangle, it's given by the following expression:

[tex]Area=\frac{base*height}{2}[/tex]

So, since we already know the area and the base, we need to isolate the height from the formula, so, isolating we have:

[tex]Area=\frac{base*height}{2}\\\\\frac{Area*2}{base}=height[/tex]

We know that:

[tex]Area=24in^{2} \\base=6in[/tex]

Now, substituting we have:

[tex]height=\frac{Area*2}{base}[/tex]

[tex]height=\frac{24in^{2} *2}{6in}=8in[/tex]

Hence, we have that the height of the triangle is equal to 8 inches.

[tex]height=8in[/tex]

Have a nice day!

For this case we have by definition, that each of the four internal angles of a square measure 90 degrees.

If we draw the diagonals of the square then the angles are divided by two, that is:

[tex]\frac {90} {2} = 45[/tex]

Thus, angle 3 measures 45 degrees.

[tex]A3 = 45[/tex]

By definition, the sum of the internal angles of a triangle is 180 degrees.

So:

[tex]A2 + A3 + 90 = 180\\A2 = 180-90-A3\\A2 = 180-90-45\\A2 = 45[/tex]

Thus, angle 2 measures 45 degrees.

Step-by-step explanation: Because of the Distributive property, you would multiply the 6 by the’x’ and 3, as they are in the parenthesis.

The distributive property is the ability of one operation to "distribute" over another operation contained inside a set of parenthesis. So, all we (you) need to do is "distribute" the 6 to the x and 3. Observe.

6(x + 3) =

6x + 18 is the rewritten equation using the distributive property.

Perimeter: 2W +2L = 48

Area = L x W = 140

Rewrite the area to solve for L: L = 140/W

Now replace that in the perimeter formula:

2W + 2(140/W) = 48

Divide all terms by 2:

W + 140/W = 24

Divide both sides by W:

140 + w^2 = 24w

Subtract 24w from both sides:

w^2 - 24w + 140 = 0

Factor:

(w-10) (w-14) = 0

Solve for each w for 0:

10-10 - 10 and 14-14 = 0

So the 2 dimensions are 10 and 14 cm.

14 isn't a choice so the answer is B. 10 cm.
