The cost to carpet the bedroom of size 11 feet × 11 feet will be equal to $1332.90.

What is area of rectangle ?

Area of rectangle is the region occupied by a rectangle within its four sides or boundaries.

It is given that size of bedroom is 11 feet by 11 feet.

Carpet costs $33.05 per square yard.

Firstly, we need to find out the the area of bedroom in feet. The room has the shape of a rectangle.

We know that , the area of rectangle is given by :

A = Length x Width.  

So ,

Area of room will be :

= 11 x 11

= 121 square feet

Convert this area of the room in square feet to square yards.

We know that , 1 feet = 1/3 yards

So , 121 square feet will be :

= 121 /3

= 40.33 square yards

So , the cost to carpet the bedroom will be :

= 40.33 x $33.05

= $1332.90

Therefore , the cost to carpet the bedroom of size 11 feet × 11 feet will be equal to $1332.90.

the slope of the linear equation is 120, then the correct option is the third counting from the top.

For any linear equation with two points (a, b) and (c, d), the slope (or rate of change) of that line is given by:

s = (d - b)/(c - a)

So here we can use the first two points so we get:

(0.5, 60)

(1.5, 180)

With these two points we will get the slope:

s = (180 - 60)/(1.5 - 0.5) = 129

We conclude that the slope is 120, then the correct option is the third counting from the top.

The bird is 1 feet below the pond relative to the surface of the water.

It is given that the bird is flying 11 feet above the pond.

So, the distance between flying bird and surface of pond = 11 Feet

Plunge steeply downward through the air or plunge head first into water.

After diving 15 feet down, it means that the bird is 4 feet under the pond as bird was flying 11 feet above the surface of pond.

So, the distance between surface of pond and the bird after diving down = 4 Feet

After that, it says that bird rises 3 feet to catch the fish,

So, after rising 3 feet above in the pond the distance between surface of pond and the bird is 1 feet.

Answer: See the diagram below

Explanation:

Start at -4 on the number line. Then move 6 units to the right to arrive at 2 on the number line.

This shows us that -4+6 = 2

Let

[tex]\displaystyle f(x) = \sum_{n=1}^\infty (-1)^{n-1} \frac{x^{2n-1}}{(2n-1)! (2n+1)}[/tex]

The exponent is indeed [tex]2n-1[/tex] - not a typo!

Take the antiderivative of [tex]f[/tex], denoted by [tex]F[/tex]. This recovers a factor of [tex]2n[/tex] in the denominator, which lets us condense it to a single factorial.

[tex]\displaystyle F(x) = \int f(x) \, dx = C + \sum_{n=1}^\infty (-1)^{n-1} \frac{x^{2n}}{(2n+1)!}[/tex]

Recall the series expansion of sine,

[tex]\displaystyle \sin(x) = \sum_{n=0}^\infty (-1)^n \frac{x^{2n+1}}{(2n+1)!}[/tex]

Then with a little algebraic manipulation, we get

[tex]\displaystyle F(x) = \int f(x) \, dx = C + 1 - \frac{\sin(x)}x[/tex]

Differentiate to recover [tex]f[/tex].

[tex]f(x) = \dfrac{\sin(x) - x\cos(x)}{x^2}[/tex]

Finally, [tex]f(\pi) = \frac1\pi[/tex], so our sum is

[tex]\displaystyle \pi^2 f(\pi) = \sum_{n=1}^\infty (-1)^{n-1} \frac{\pi^{2n+1}}{(2n-1)! (2n+1)} = \boxed{\pi}[/tex]

Answer:

13.

Step-by-step explanation:

1) if the required number of years is 'x', then it is possbile to make up the equation:

43+x=2(15+x);

2) finally, x=13 [years].

The relationship c(x) = 4.5+ 0.32x it is a linear relationship.

The factor 0.32 is used to reduce the cost of the weight before adding to the fixed cost of  4.5

Given data

c(x) = 4.5+ 0.32x

The relationship c(x) = 4.5+ 0.32x it is a linear relationship.  It can be compared to the equation of a straight line which is

y = mx + c

m is the slope and c is the y intercept

The comparison shows that

y = c(x)

c = 4.5

m = 0.32

If the cost is related with the relationship c(x) = 4.5+ 0.32x.

it can be seen that even when there is no weight or no salad that is at    x = 0 the cost is c = 4.5.

This means that there is a fixed cost of 4.5 for any salad weight, in ounces bought.

The factor 0.32 is used to reduce the cost of the weight before adding to the fixed cost of  4.5.

The 0.32 is a reduction factor because the value is less than 1 and will reduce any number it multiplies.

The correct option is (3) 5/2

The slope of a line perpendicular to m is 5/2.

The slope of a line can be find by dividing its vertical change, or the rise of line by its horizontal change or the run . No matter which two locations on the line you choose, the slope of a line is always constant (it never varies). The word "slope" is represented by the letter "m," and it describes how steep a line is.

In the given question,

from the graph take any two points on the line say point A (2,1) and point B (-3,3)

now using the slope formula,

slope = m1 = [tex]\frac{delta \ Y}{delta \ X} = \frac{y2-y1}{x2-x1}[/tex]

=> m1 = [tex]\frac{3-1}{-3-2} = - \frac{2}{5}[/tex]

Now, for perpendicular lines:

m1.m2 = -1

=> m2 = 5/2

Thus, slope of a line perpendicular to m is 5/2.

The solution to the system of linear equations is (x, y) = (2, 3).

Graphic methods are useful to solve systems of two linear equations with two variables, as it is seen in the statement of the problem. In accordance with geometry, a line can be constructed by knowing the coordinates of two distinct points on Cartesian plane. First, rewrite each linear equation into its explicit form:

y = 2 · x - 1                      (1)

y = - 3 · x + 9                  (2)

Second, look for two points lying on each line:

y = 2 · x - 1

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

y = - 3 · x + 9

(0, 9) and (- 3, 6)

Third, plot the points on a Cartesian plane and pass each line through corresponding pair of points. The result is presented by the image attached below.

The solution to this system is the point of intersection of the two lines. The point of intersection is (2, 3).

The value of 1,999,999 with an exponent of 0 is 1,999,999 × 10⁰

Exponentiation is a mathematical process that involves the base b and the exponent or power n. It is represented as bn and is pronounced as "b to the n."

Knowing that every number raised to the power of zero equals one is necessary before we can simplify using a zero exponent. Hence:

1,999,999 = 1,999,999 × 1

Since 1 can be expressed as 10⁰, the value becomes:

1,999,999 = 1,999,999 × 10⁰

W=[tex]\frac{1}{2} k(x-x_{0} )^{2}[/tex] , where W is the work done, x is the final length of the spring

We have to find out the work done to get to 7cma nd 9cm separately and then subtract one from the other to get the work done to stretch from 7cm to 9cm. We repeat the process for 9cm and 11cm and we will find the final result which is the natural length.

There’s a simple formula which governs the three, and it can be expressed with either variable as the subject of the equation:

Distance = speed * time

Time = distance/speed

Speed = distance/time

So, as long as we have a couple of those, we can plug them into one of the equations.

Time = distance/speed. So, a nice easy one would be how many hours does it take to cover 30km when you are travelling at 120km/h.

Time = 30km/120km/h = 0.25 hours.

If you need to figure out how many minutes that is, simply multiply it by 60, which gives you 15 minutes.

You’re going to drive at an average of 70km/h for 4 hours.

Distance is speed multiplied by time, so:

70km/h * 4 hours = 280km.

Easy so far, but what about if you’re going to be driving for 4 hours and 15 minutes? Now you either need to figure out how much 15 minutes is as a decimal number of hours, or you need to convert the hours figure into minutes and, at the end, convert it back.

The first option is fairly simple: take the 15 minutes and divide it by 60 minutes so that we know what proportion of an hour 15 minutes is.

15 minutes / 60 minutes = 0.25 hours

Add that onto the 4 hours you already have and it’s 4.25 hours. Plug it into the same equation:

70km/h * 4.25 hours = 297.5km

The other way around of doing this is converting the time into minutes. Four hours in minutes is 4 * 60 = 240 minutes.
