If x = 2 calculate the value of x squared- x

Answer:

392 ft²

Step-by-step explanation:

Break this area into two parts, that is, into two trapezoids.  The first trapezoid, on the left, has length 8 ft and average length (30 ft + 27 ft)/2, so its area is (8 ft)(28.5 ft) = 228 ft ².

The second trapezoid has width 8 ft and average length (19 + 22)/2 ft, or 8 ft by 20.5 ft).  The area of this part is 164 ft².

Thus, the total area is 164 ft² + 228 ft², or 392 ft²

Answer:

4/21

Step-by-step explanation:

⇒This question is on probability

⇒Number of boys=3

⇒Number of girls=4

⇒P(S)= 4+3=7

Probability for a girl to win is= 4/7

We have 3 awards a free movie ticket, a collectible poster, or a free popcorn

P(S)= 3

Probability of being awarded a free popcorn = 1/3

The probability that a girl will win free popcorn =

Step-by-step explanation:

This statement is true.

When you buy a share in a company, you are investing your money, and you may earn more money if the share’s value rises, or you may lose money if the share’s value falls.

Investing in a company by buying shares makes you a shareholder, with potential income from dividends and stock appreciation. However, it carries risk as there is no guarantee for profits. Diversification is a key strategy when investing in stocks to mitigate risks.

Buying shares in a company is a common method of investment, wherein you become a shareholder and own a part of the company's equity. As a shareholder, you have a claim to the company's assets and profits proportional to the amount of stock you own. There are two primary ways that shareholders can earn money from their investments. One way is through dividends, which are payments distributed from the company's profit to shareholders. The other way is through appreciation in the stock's value, as the company grows and becomes more profitable; this increases the stock's market price, and you can sell your shares for a profit. It's important to understand that purchasing stock does involve risk, as there is no guarantee of dividends or stock appreciation. However, for many, owning stock is preferred over other investments like bonds because of the potential for higher returns. Lastly, when buying stock, especially that of your employer, it's advisable to follow general rules of portfolio investing, such as diversification, not to expose yourself to undue risk.

x=28 (Yup you're correct)

Step-by-step explanation:

As this problem is involving the Opposite angle and the Hypotenuse, we can use the sin function in order to solve this. The setup is as follows

[tex]sin(30)=\frac{14}{x}[/tex]

Now we can solve for x

[tex]sin(30)=\frac{14}{x}\\\\x=\frac{14}{sin(30)}[/tex]

Now we can plug it into a calculator to get

[tex]x=28[/tex]

Answer:

Step-by-step explanation:

(Look at the picture)

We have the triangle 30° - 60° - 90°. The sides are in ratio 1 : √3 : 2.

We have a = 14. Therefore x = 2a ⇒ x = 2(14) = 28

Answer:

$482.11 in interest

Step-by-step explanation:

Use the compound amount formula.  Calculate the compound amount and then subtract the principle to find the amount of interest earned.

A = P(1 + r)^t, where r is the interest rate as a decimal fraction

This becomes:

A = $575(1 + 0.07)^9, or A = $1057.11.

Subtracting the principal:  A - P:  $1057.11 - $575 = $402.11

The total interest earned is $482 on a principal of $575 invested at an interest rate of 7% compounded annually for nine years

Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.

We know the formula for compound interest is,

A = P(1 + r/100)ⁿ.

Where, A = amount, P = principle, r = rate, and n = time in years.

Given, P = $575, n = 9 and r = 7%.

∴ A = 575(1 + 7/100)⁹.

A = 575(1.07)⁹.

A = 575(1.84).

A = 1057.

So, Interest earned is (A - P) = (1057 - 575) = $482.

The correct answer is 6

Answer:

Option B is the correct answer

Step-by-step explanation:

Both collections follow arithmetic progression.

Back then, they had the same number of rare coins, which means their first term of AP is same. Let it be a.

Miguel's AP have a common difference 5 and Grace's AP have a common difference 3.

Let the number of weeks completed be n.

We have

           a + ( n-1 )x 5 = 38  -------- eqn 1

           a + ( n-1 )x 3 = 24  -------- eqn 2

eqn 1 - eqn 2

          a + ( n-1 )x 5 - (a + ( n-1 )x 3) = 38 - 24

          ( n-1 )x 2 = 14

          n-1 = 7

          n = 8

Substituting in eqn 1

           a + ( 8-1 )x 5 = 38

                     a = 38 - 35 =3

So at starting they both have 3 rare coins.

Total rare coins = 3 + 3 = 6

Option B is the correct answer

-3+m/9=10

Add 3 to both sides:

m/9 = 13

Multiply both sides by 9:

m = 13 * 9

m = 117

domain : x ∈ R

321

Look for a pattern: The term is 11 more than the number before. this means 11 is added each time.

Since you start with 2 and the number goes up by 11 per term, the equation you would use to find the nth term would be 11n+2

To find the 29th term, simply plug in 29

11n+2

11(29)+2

321 

The 29th term is 321.

First you have to find the rate of change. It would be 11 because 35 - 24 = 11, 24 - 13 = 11 and 13 - 2 = 11.

These are the first 4 terms so just keep adding on 11 until you get 29 terms.

2, 13, 24, 35, 46, 57, 68, 79, 90, 101, 112, 123, 134, 145, 156, 167, 178, 189

Solution

In Δ A OD

Represent the center of circle by O.

The mapping for a reflection in the line y=x is

The line y=x is the mirror line for a function and it's inverse.

The x and y coordinates swap position.

The reflection of point P(−1, 6) across the line y = x is

P'(6,-1)

Answer: [tex]g(x)=(3)^{-x}[/tex]

Step-by-step explanation:

We know that if a figure is reflected across y axis then its y coordinate remains same but the x coordinate changes its polarity.

i.e. the function [tex]f(x)[/tex] will become [tex]f(-x)[/tex] .

Now, the given function :[tex]f(x)=(3)^x[/tex]

Then , after reflection across y axis the new function will become:

Answer:

x⁸y³

Step-by-step explanation:

x⁵ ÷ y² × x³ × y⁵

It will be easier to solve this problem if you first rearrange the expression to associate like terms.

(x⁵ × x³) × (y⁵ ÷ y²)

Now, you can use the rules of exponents: When multiplying, you add exponents; when dividing, you subtract exponents.

x⁵ × x³ = x⁵⁺³ = x⁸  

y⁵ ÷ y² = y⁵⁻² = y³

Thus,

(x⁵ × x³) × (y⁵ ÷ y²) = x⁸y³

ANSWER

The y-intercept is (0,-11)

The x-intercepts are:

(-1,0) and (11,0)

EXPLANATION

The given function is

[tex]f(x) = {x}^{2} - 10x - 11[/tex]

To find the y-intercept, we put x=0 into the function.

[tex]f(0) = {0}^{2} - 10(0) - 11[/tex]

[tex]f(0) = - 11[/tex]

The y-intercept is (0,-11)

To find the x-intercepts, we put f(x)=0.

[tex]{x}^{2} - 10x - 11 = 0[/tex]

[tex](x + 1)(x - 11) = 0[/tex]

This implies that,

[tex]x = - 1 \: or \: x = 11[/tex]

The x-intercepts are:

(-1,0) and (11,0)
