The area of a square is length*width and since a square has the same side measurements, √1225 or 35 is one side. (35 * 35 = 1225)

There are 4 sides so 35*4 = 140ft² as the perimeter

I hope this helps!

Answer:

140 ft

Step-by-step explanation:

Here, A = 1225 ft² = s², where s represents the length of one side of the room.  Here, s = √( 1225 ft² ) = 35 ft.

Thus, the perimeter, P = 2L + 2W, is 4(35 ft) = 140 ft

Answer:

D, x = 3

Step-by-step explanation:

to know if a line is parallel, we need to know what kind of line x = 6 is

we can use the mnemonic VUX/HOY to determine the slope, the type of line, and which axis it corresponds to. VUX/HOY stands for:

Vertical line

Undefined slope

X axis

Horizontal line

0 is the slope

Y axis

according to this, the equation x = 6 is a vertical line

now we can start eliminating answer choices

A. a line containing the point (6,2)

the point lies on the line x = 6, as the x-coordinate in the ordered pair is 6. this  is not parallel to the line

B. y = 6

this intersects x = 6 and is not parallel

C. y = 4

this intersects x = 6 as well and is not parallel

D. x = 3

this leaves us with x = 3, which is a vertical line as seen by the equation and therefore x = 3 is our answer

Supplementary angles are angles that add up to 180 degrees, aka one straight line. The supplementary angles here are:

1 and 2, 1 and 3, 2 and 4, 3 and 4, 5 and 6, 6 and 8, 7 and 8, and 6 and 7. Well, those are the more obvious ones. 1 and 7 are supplementary because if you envision them next to each other, you’ll see that they create a straight line. So, with that logic, 3 and 5 are supplementary because when you put them together, they create a straight line

Angle ∠5 and angle ∠3 are supplementary angles. Then the correct option is C.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.

From the figure, the supplementary are given below.

x + 2x + 15 = 63

Combine like terms:

Answer:

[tex]x_1=4\\x_2=-3[/tex]

Step-by-step explanation:

Multiply both sides of the equation by -1:

[tex](-1)(-x^2+x+12)=0(-1)\\x^2-x-12=0[/tex]

Now, you can Factor the quadratic equation to solve it:

Choose two number that when you multiply them you get -12 and when you add them you get -1. These numbers are: -4 and 3

Therefore, you get:

[tex](x-4)(x+3)=0\\x_1=4\\x_2=-3[/tex]

For this case we have the following quadratic equation:

[tex]-x ^ 2 + x + 12 = 0[/tex]

We can solve it by:

[tex]x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2 (a)}[/tex]

Where:

[tex]a = -1\\b = 1\\c = 12[/tex]

Substituting:

[tex]x = \frac {-1 \pm \sqrt {1 ^ 2-4 (-1) (12)}} {2 (-1)}\\x = \frac {-1 \pm \sqrt {1 + 48}} {- 2}\\x = \frac {-1 \pm \sqrt {49}} {- 2}\\x = \frac {-1 \pm \sqrt {49}} {- 2}\\x = \frac {-1 \pm7} {- 2}[/tex]

We have two roots:

[tex]x_ {1} = \frac {-1 + 7} {- 2} = \frac {6} {- 2} = - 3\\x_ {2} = \frac {-1-7} {- 2} = \frac {-8} {- 2} = 4[/tex]

Answer:

[tex]x_ {1} = - 3\\x_ {2} = 4[/tex]

The answer is 2/5. (or 0.4 if you need a decimal answer.)

For this case we have that by definition, the slope of a line is given by:

[tex]m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}[/tex]

We must find two points through which the line passes:

[tex](x_ {1}, y_ {1}) :( 2,3)\\(x_ {2}, y_ {2}}: (- 3,1)[/tex]

Substituting:

[tex]m = \frac {1-3} {- 3-2} = \frac {-2} {- 5} = \frac {2} {5}[/tex]

Answer:

[tex]m = \frac {2} {5}[/tex]

Answer:

First option: You start with $3 and save $1 each month.

In this case, the relationship is linear. So the corresponding equation is: y=x+3. Where 'x' represents the month. For example, the amount of money that you will have after 7 months is going to be: y = 7 + 3 = 10. (Ten dollars).

Second option: You save $3 the first month, and then each month the amount triples.

In this case, the relationship is exponential. If each month the amount triples, it means that the first month you have $3, the second month $9 and the third month $27. The equation that correctly models this situation is [tex]y=3^{x}[/tex]. For example, the amount of money that you will have after 7 months is going to be [tex]y=3^{7} = 2187[/tex] (2187 dollars)

Third option: Your total savings is 3 times the number of months multiplied by itself.

In this case, the relation is quadratic. So the equation that models this situation is: [tex]y=3x^{2}[/tex]. For example, the amount of money that you will have after 7 months is going to be [tex]y=3(7)^{2} = 147[/tex] (147 dollars)

The equation of the parabola with vertex (2, -4) and directrix y = -6 is y = 0.25(x - 2)² - 4.

The equation of a parabola in vertex form is y = a(x - h)² + k, where (h, k) is the vertex, and a is a constant that determines the shape and direction of the parabola. Given the vertex (2, -4) and the directrix y = -6, we can determine the value of a using the formula a = 1 / 4(c), where c is the distance from the vertex to the directrix. Since the vertex lies two units above the directrix, the constant c = 2; hence, a = 1 / 4(2) = 0.25 or 1/4.

Thus, the equation of the parabola is y = 0.25(x - 2)² - 4.

Answer:

72fl

Step-by-step

For this case we must find the inverse of the following function:

[tex]f (x) = x ^ 2-1[/tex]

For them we follow the steps:

We change f (x) to y:

[tex]y = x ^ 2-1[/tex]

We exchange variables:

[tex]x = y ^ 2-1[/tex]

We solve for "y":

[tex]y ^ 2-1 = x[/tex]

We add 1 to both sides of the equation:

[tex]y ^ 2 = x + 1[/tex]

We apply square root to eliminate the exponent:

[tex]y = \pm \sqrt {x + 1}[/tex]

We change y by [tex]f ^ {- 1} (x)[/tex]:

[tex]f ^ {- 1} (x) =\pm \sqrt {x + 1}[/tex]

Answer:

Option D

Answer:

Step-by-step explanation:

Given:  f(x)=5x^3-51x^2+77x+100/x^2-11x+24

Please use parentheses to eliminate any ambiguity:

      f(x) = (5x^3-51x^2+77x+100) / (x^2 - 11x + 24)

or (better yet):

                  5x^3-51x^2+77x+100

        f(x) = ---------------------------------

                      x^2 - 11x + 24

The vertical asymptotes here are at the zeros of the denominator:

x^2 - 11x + 24 = 0,  This quadratic equation has coefficients a = 1, b = -11 and c = 24.  Thus, its roots (zeros) are:

       -(-11) ± √( 121 - 4(1)(24) )

x = -------------------------------------

                    2(1)

or:

        11 ± √( 25 )

x = --------------------

                 2

or:  x = 8 and x = 3

The vertical asymptotes are x = 8 and x = 3.

If we attempt to divide x^2 - 11x + 24 into 5x^3 - 51x^2 + 77x + 100, we see that the first term of the quotient is 5x.  As x increases or decreases without bound, 5x goes to either ∞ or -∞, so we conclude that there is no horiz. asymptote.  Continuing this division results in:

5x + 4 + a fraction

This represents the slant asymptote, y = 5x + 4

Colin will have £1344 in his bank account after 4 years. This is calculated using the simple interest formula I = PRT (Interest = Principal x Rate x Time) yielding an interest earned of £144 over four years, which was then added to the initial investment.

First, understand that simple interest is calculated as (principal amount × interest rate × time in years). The principal amount here is £1200, the interest rate is 3%, and the time period is 4 years.

Before doing the calculation, convert the 3% interest rate into decimal form by dividing by 100, yielding 0.03.

War is represented by the formula I = PRT, which means Interest = Principal x Rate x Time. So, use these values in the formula: £1200 * 0.03 * 4. This gives you £144, which is the interest earned after 4 years.

To find the total amount in Colin's account after 4 years, you need to add the interest earned to the principal amount. Therefore, £1200 (original amount) + £144 (interest) = £1344.

So, after 4 years, Colin will have £1344 in his bank account.

After 9 movies they will have paid the same amount

Step-by-step explanation:

We must write an equation for Duke's expenses and an equation to represent Tennessee's expenses.

For Duke expenses we have:

A fixed expense of $ 111.60 per year

A variable expense of $ 4.00 for each movie.

The equation that represents the expenses is a linear equation like the one shown below

[tex]C = 111.60 + 4.00x[/tex]

Where C represents the cost and x the number of movies.

For Tennessee expenses we have:

A variable expense of $ 16.40 for each film.

The equation that represents the expenses is a linear equation like the one shown below

[tex]C = 16.40x[/tex]

Where C represents the cost and x the number of movies.

To know after how many movies have paid the same amount, we equate both equations and solve the variable x

[tex]111.60 +4.00x=16.40x\\\\16.40x - 4x = 111.60\\\\12.40x =111.60\\\\x =\frac{111.60}{12.40}\\\\x =9[/tex]
