What is 300 to the power of 10?

Answer:

The simplified expression to represent the scenario is Y = 4·X - 0.48·X

Step-by-step explanation:

The given parameters are;

The number of tickets required = 4

The amount of discount offered = 12%

Let the selling price = X

Therefore the amount paid for each ticket = X - X×12 %

Which gives;

The amount paid for each ticket = X - X×0.12

The amount paid for the four tickets = 4 × (X - X×0.12) = 4·X - 4×0.12·X =  4·X - 0.48·X

Whereby the amount paid for the four tickets = Y, we have;

Y = 4·X - 0.48·X

Which gives, the simplified expression to represent the scenario as Y = 4·X - 0.48·X.

Answer:

(5 + 3y)(25 - 15y + 9y²)

Step-by-step explanation:

This is a sum of cubes and factors in general as

a³ + b³ = (a + b)(a² - ab + b²), thus

125 + 27y³

= 5³ + (3y)³ with a = 5 and b = 3y

= (5 + 3y)(5² - 5(3y) + (3y)² )

= (5 + 3y)(25 - 15y + 9y²)

Answer:

8.726%

Step-by-step explanation:

Purchase price = $45.23

Current selling price of stock = $52.00

Intended increase before sale = 25%

25% of purchase price :

100% + 25% = 125%

125% of $45.23

1.25 × 45.23 = $56.5375

$56.5375 is the price at which Mason intends to sell the stock after purchase.

If current price = $52.00;

What percentage increase above the current price is $56.5375.

Let the percentage increase = p

Therefore,

p% of $52 = $56.5375

(p/100) * 52 = 56.5375

52p/100 = 56.5375

52p = 5653.75

p = 5653.75 / 52

P = 108.72596

Therefore p = 108.72596% - 100%

The percentage increase above the current price is thus :

8.72596%

= 8.726%

Answer:

The correct option is;

720 unit²

Step-by-step explanation:

The given dimension of square pyramid is given as follows;

The length and width of the square prism = w = 12 units

The height of the square prism = x = 7 units

The base width of the pyramid = w = 12 units

The formula of the area of the square prism = 2 × w² + w × x × 4

∴ The area of the square prism = 2 × 12² + 12 × 7 × 4 = 624 unit²

The area of the square pyramid = w² + 1/2×4×w ×√((w/2)² + y²)

The area of the square pyramid = 12² + 1/2×4×12×√((12/2)² + 8²) = 12² +240 unit²

The formula for the surface area of the figure = The slant surface area of the square prism  + The area of the base of the square prism + The slant surface area of the square pyramid

The surface area of the figure = 12² + 12 × 7 × 4 + 1/2×4×12×√((12/2)² + 8²) = 720 unit²

The surface area of the figure = 720 unit².

The cost for 4 hours is 850, the cost for 7 hours is 1300 then the cost for 12 hours will be equal to 1906.8.

The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers. Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.

As per the data given in the question,

Cost for 4 hours = 850

4 × 212.5 = 850

Cost for 7 hours = 1300

7 × 185.7 = 1300

The rate at which it is increasing,

212.5 - 185.7 = 26.8

For 12 hours,

185.7 - 26.8 = 158.9

12 × 158.9 = 1906.8

NOTE: NEGATIVE EXPONENTS DOES NOT MEAN IT IS A NEGATIVE NUMBER, IT IS STILL A POSITIVE NUMBER IF THE BASE IS POSITIVE.

The domain, which will be the value of x.

x can be any real number, except 0, because 0 can't go to negative exponents or else it will be undefined.

{x|x<0 or x>0}

-------------------------------------

The range, which will be the value of y.

Since the x value is being squared, it is always positive

{y|y>0}

Answer:

A. The first choice.

Step-by-step explanation:

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

Let's rewrite the function in a more familiar way.

[tex] f(x) = \dfrac{1}{x^2} [/tex]

Domain:

We know that a denominator cannot equal zero, so we set the denominator equal to zero to find the values of x that must be excluded from the domain.

x^2 = 0

x = 0

The only value excluded from the domain is x = 0.

The domain is all reals except for zero.

Range:

Now that we know the domain is all real numbers except for 0, we look closely at the denominator.

What happens when you replace x with negative numbers? Since you are squaring x, all denominators will be positive. When you replace x with positive numbers, all denominators will also be positive. For values of x with a large absolute value, for example 1000, -1000, 1,000,000 or -1,000,000, as the absolute value of x increases, f(x) approaches zero. For values of x with a small absolute value, such as 0.0001, -0.0001, -0.00000001, or 0.00000001, as x approaches zero, f(x) approaches positive infinity.

The range is all positive real numbers.

Answer:

Domain: all real numbers except 0.

Range: all positive real numbers.

[tex]\bold{x=\dfrac{-3\pm i\sqrt{7}}{2}}[/tex]

Step-by-step explanation:

Given quadratic equation is:

[tex]-x^2 - 3x = 4[/tex]

Rewriting the given equation:

[tex]-x^2 - 3x - 4 = 0[/tex]

OR

[tex]x^2 + 3x + 4=0[/tex]

Solution of a quadratic equation represented as [tex]ax^2+bx+c=0[/tex] is given as:

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

Comparing the given equation with standard equation:

a = 1

b = 3

c = 4

So, the roots are:

[tex]x=\dfrac{-3\pm\sqrt{3^2-4\times 1 \times 4}}{2\times 1}\\\Rightarrow x=\dfrac{-3\pm\sqrt{9-16}}{2}\\\Rightarrow x=\dfrac{-3\pm\sqrt{-7}}{2}[/tex]

[tex]\sqrt{-7 }[/tex] can be written as [tex]7\sqrt{-1}[/tex]

and [tex]\sqrt{-1} = i[/tex]

So, [tex]\sqrt{-7} = i\sqrt7[/tex]

The numbers containing [tex]i[/tex] in them, are called as complex numbers.

Therefore, the roots of the equation can be written as:

[tex]\Rightarrow \bold{x=\dfrac{-3\pm i\sqrt{7}}{2}}[/tex]

The correct option is;

10.25 + (-3.5) = 6.75

Step-by-step explanation:

We note that when adding numbers the negative sign is equivalent to the minus sign which is a mathematical operator. Therefore, when we subtract one number from another, it is equivalent to adding the negative of the other number to the first number

The given expression is 10.25 - (3.5)

The result of the given expression is 10.25 - (3.5) = 6.5

Therefore, we have;

10.25 + (-3.5) = 6.75

Answer:

Step-by-step explanation:

Let x = number of 50.00 notes.

They are worth 50x

Then, 2x = number of 20.00 notes.

They are worth 2x * 20 = 40x

50x + 40x < 1100

90x < 1100

9x < 110

x < 12.2

Answer: 12

Check:

x = 12   (number of 50.00 notes)

2x = 24    (number of 20.00 notes)

12 * 50 + 24 * 20 = 1080

If she used one more 50.00 note, she'd go over 1,100, so 12 is correct.

Step-by-step explanation:

Al + O2 → Al2O3

first step to balance the equation is :

multiply AL by 2 to match the amount of aluminum on the other side

but then you have to deal with the amount of O from both sides, we need to find the least common multiple between 2 and 3 which is 6

the best thing to balance the equation is to multiply O2 by 3 and O3 by2, then deal with the amount of AL which is 4 on the other side. last step is to multiply AL by 4 to balance the equation.

Answer:

(- 4, 2 )

Step-by-step explanation:

Under a reflection in the x- axis

a point (x, y )→ (x, - y ), thus

(- 4, - 2 ) → (- 4, 2 )

The image of the coordinate after a reflection over the x-axis is (-4, 2).

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the x-axis is (x, -y).

The given coordinate point is (-4, -2).

The rule of reflection is (x, y)→(x, -y)

Here, (-4, -2)→(-4, -(-2))

= (-4, 2)

Therefore, the image of the coordinate is (-4, 2).

Answer:

[tex]LO = OT = 8cm[/tex]

Step-by-step explanation:

Given

LT = 16cm

Required

Determine LO and OT

First, we have:

[tex]LO + OT = LT[/tex]

From the question, we understand that O is the middle of LT

This implies that LO = OT

Substitute OT for LO in the above formula

[tex]OT + OT = LT[/tex]

[tex]2OT = LT[/tex]

Divide both sides by 2

[tex]OT = \frac{1}{2}LT[/tex]

Substitute 16cm for LT

[tex]OT = \frac{1}{2} * 16cm[/tex]

[tex]OT = 8cm[/tex]

Recall that LO = OT

So;

[tex]LO = OT = 8cm[/tex]
