(C)11 and every whole number greater than 11

(D)a rational number infinitely close to 10 but greater than 10, and all other whole numbers greater than 10

Answer:

C)

Step-by-step explanation:

To find area, You use the equation (Length × Width). If you need to find the perimeter By using the Area, You need to Divide one of the Equal Sides, since it is a square you can use either length or width, So Since it is a square, You Can also use the Square Root method. Square root is basically Dividing the number by the number it was multiplied by.

EX:

9 × 9 = 81

because

81 ÷ 9 = 9

So, If both the Length and width are 9, You add them together to get eighteen. Though since it's a square, You Can't only Count The Half of the Shape, So you multiply that by two, Leaving you with 36

Answer: C) 36 ft

To solve this equation, we need to fin out how long each side is. To do this, find the square root of 81, since it is a perfect square.

[tex]\sqrt{81 ft} = 9 ft[/tex]

So now we know that each side is 9 feet, we need to find the perimeter of the square using these dimensions.

9 ft · 4 sides = 36 ft of fencing

Therefore, Ariel needs 36 ft of fencing for her garden.

Answer:

-7 + a = 37

Step-by-step explanation:

The value of 'a' is 44 and the equation for the statement "The sum of -7 and a is equal to 37" is -7 + a = 37

Let's start by writing the equation for the given statement:

-7 + a = 37

To find the value of 'a', we need to isolate 'a' on one side of the equation. We can do this by performing inverse operations. The inverse of subtracting 7 is adding 7. So, we will add 7 to both sides of the equation:

-7 + a + 7 = 37 + 7

On the left side, the -7 and +7 cancel out, leaving us with:

a = 44

Therefore, the value of 'a' that satisfies the given equation is 44.

Step-by-step explanation:

Unit vector is a vector with mangnitue 1 and we can find out the magnitude of the vector [tex]u = (x , y)[/tex] with the following formula

[tex]magnitude = \sqrt{x^{2}+y^{2}}[/tex]

So in the given options whichever vector has magnitude 1 it will be a unit vector.

So if we put the values in the above mentioned formula

1.Magnitude of option A is not 1 so it is not a unit vector

2.Magnitude of option B is  1 so it is a unit vector

3.Magnitude of option C is  1 so it is a unit vector

4.Magnitude of option D is not 1 so it is not a unit vector

A unit vector is of length 1 and is used to represent the positive direction on an axis in a Cartesian system. In mathematics, the i, j, and k unit vectors denote the positive directions on the X, Y, and Z axes, respectively. The magnitudes of all unit vectors are one, and they are crucial in representing directions in space.

In mathematics, a unit vector is a vector of length 1. The unit vectors in a Cartesian system are typically denoted as i, j, and k. Unit vector i signifies the positive direction on the X-axis, while unit vector j represents the positive direction on the Y-axis. In three-dimensional space, unit vector k denotes the positive direction on the Z-axis.

For example, Consider any vector A in a Cartesian coordinate system (figure 2.16). The scalar x-component of vector A is its dot product with the unit vector i, while the scalar y-component of that vector is its dot product with the unit vector j. This approach effectively expresses A in terms of the unit vectors of the axes. By their very definition, these unit vectors are dimensionless, such as their direction allows precise representations of vectors in space.

In summary, unit vectors essentially establish the directions for the system of coordinates in question. These vectors assist in expressing the direction of physical entities, such as the projection of vector A onto the x-axis or the y-axis. The magnitudes of these unit vectors are always one, so their principal significance comes from the directions they represent.

Step-by-step explanation:

Answer:

The slope is 14/1, meaning you rise 14, then run 1. This is a steep slope.

Step-by-step explanation:

The slope equation is y=mx+b. The "m" in the equation is equal to the slope. In your case, 14 takes the place of the "m", making it the slope.

The slope of the equation y = 14x + 10 is 14, which means the line has a positive slope, indicating a rise of 14 units in y for each unit increase in x. The y-intercept of the line is 10.

The equation given is y = 14x + 10. To understand the slope of this linear equation, we can refer to the formula y = mx + b, where m represents the slope and b represents the y-intercept. In this case, the number 14 is the coefficient of x, which means the slope of the line is 14. This indicates that for each unit increase in x, the value of y will increase by 14 units. Therefore, the line represented by this equation has a positive slope, which tells us that as x increases, y also increases at a constant rate. The slope is important in many fields, including economics, as it measures the relationship between two variables.

The y-intercept is the point where the line crosses the y-axis, which occurs when x equals 0. In our equation, the y-intercept is 10, indicating that the line crosses the y-axis at the point (0, 10).

System of equations have infinitely many solution for x and y.

We have to given that,

System of equation are,

3x + 2y = 12

3x + 2y = 12  .. (i)

12x + 8y = 48  .. (ii)

Multiply by 4 in (i) and subtract from (ii);

[tex]\tt length=\cfrac{area}{width}\\\\\\ length=\cfrac{24x^3-76x^2-28x}{12x^2+4x}=\cfrac{4x(6x^2-19x-7)}{4x(3x+1)}=\\\\\\=\cfrac{6x^2+2x-21x-7}{3x+1}=\cfrac{2x(3x+1)-7(3x+1)}{3x+1}=\\\\\\=\cfrac{(3x+1)(2x-7)}{3x+1}=2x-7[/tex]

The length of the rectangle can be found by dividing the area given as (24x³-76x²-28x) by the width given as (12x²+4x). This simplifies to 2x - 7 units which is the expression for the length of this rectangle.

In mathematics, to find the length of a rectangle when given the area and the width, you have to divide the area by the width. The area A is given as 24x³-76x²-28x square units, and the width w is given as (12x²+4x) units. Following the formula A = lw, where l is length and w is width, the length can be found by rearranging this formula to l = A/w.

Applying this to the given values: l = (24x³-76x²-28x) / (12x²+4x) simplifies to l = 2x - 7 units. Therefore, the expression for the length of the rectangle is 2x - 7 units.

Answer:

Option A) y=1000(1.15)^6   2313 bacteria

Step-by-step explanation:

The initial value is 1,000 and the growth factor would be the the 15%.

15% can be rewritten to .15, but you have to have to add 1 for the start to make the equation easier. Thus making the growth factor 1.15

After multiplying 1000(1.15)^6 you will get 2313.06076562 which is simplified to 2,313 bacteria.

Hope this is helpful. :)

The population of the culture 6 days after inoculation is y = 1,000(1.15) 2,313 bacteria.

According to the given statement, a growth medium exists inoculated with 1,000 bacteria.

Bacteria grow at a rate of 15% = 0.15

Add 1 to create it easier = 0.15 + 1 = 1.15

We have to estimate the population of the culture 6 days after inoculation.

[tex]= 1000(1.15)^6[/tex]

= 1000(2.313)

= 2313 bacteria

The population of the culture 6 days after inoculation = 2313 bacteria

c = 6t + 19.60

Step-by-step explanation:

   Let t = the time in hours for which Beth rented the bike. Then  

       6t = the rental cost for the bike and

$19.60 = the up-front cost

The expression for the total cost (c) is

c = 6t + 19.60

The expression for the total cost is C = 19.60 + 6t. According to the given statements, time t is the variable term.

An expression is the combination of variables, coefficients, and constants. These are separated by operators like addition or subtraction. Each combination is called a term.

Given that,

Beth rented a bike from Julia's Bikes.

It cost $19.60 plus $6 per hour.

So, here the variable is time because as the time increases the cost also increases.

Step-by-step explanation:

You first need to find the area of the circle.

4 is radius. r*r*3.14=50.24

Now the triangle is 4*4=16.

50.24-16= 34.24

Answer:

B.

Step-by-step explanation:

The area of the shaded region will be the area of the circle minus the area of the triangle inside the circle. Then:

The circle has radius 4 cm (distance from the center to the edge of the circle), so the area of the circle is

[tex]A=\pi r^2 = 3.14(4cm)^2 = 3.14(16cm^2) = 50.24 cm^2.[/tex]

Now, the area of the triangle is

[tex]A_2 = \frac{b*h}{2}[/tex].

The base of the triangle is the diameter of the circle (as you can see in the image) and the height is the radius of the circle. Then the are of the triangle is

[tex]A_2 = \frac{8*4}{2} = \frac{32}{2} = 16cm^2[/tex].

840+42=882

We will have a total of 882 employees.

The percentage is defined as a ratio expressed as a fraction of 100.

For example, If Misha obtained a score of 67% on her exam, that corresponds to 67 out of 100. It is expressed as 67/100 in fractional form and as 67:100 in ratio form.

Last year at this time we had 840 employees.

Since that time our staff has increased by 5%.

We have to determine the employees will we have in total

The total employees = 840 + 5% of 840

The total employees = 840 + 0.05 × 840

The total employees = 840 + 42

The total employees = 882

Hence, there are 882 employees will we have in total.

Answer:

[tex]y-5=\frac{-1}{2}(x+2)[/tex] point-slope form

[tex]y=\frac{-1}{2}x+4[/tex]  slope-intercept form

Step-by-step explanation:

The slope-intercept form of a line is y=mx+b where m is the slope and b is the y-intercept.

The slopes of perpendicular lines are opposite reciprocals.

The slope of y=2x-5 is 2.

So we are looking for a line perpendicular to y=2x-5 which means we first to the take the opposite reciprocal of it's slope giving us:

opposite reciprocal of (2) is opposite (1/2)=-1/2.

So the slope of the line we are looking for is -1/2.

This means are equation for our line is in this form:

[tex]y=\frac{-1}{2}x+b[/tex]

To find b we will use a point (x,y) that is on our line.

We are given a point (x,y)=(-2,5).

Plug this into our equation:

[tex]5=\frac{-1}{2}(-2)+b[/tex]

[tex]5=1+b[/tex]

Subtract 1 on both sides:

[tex]4=b[/tex]

So the equation for our line that we are looking for is:

[tex]y=\frac{-1}{2}x+4[/tex]  (slope-intercept form).

You could also go for point-slope form [tex]y-y_1=m(x-x_1)[/tex] where m is the slope and [tex](x_1,y_1)[/tex] is a point on the line.

We have m=-1/2 and (x1,y1)=(-2,5) so our equation in point slope-form is:

 [tex]y-5=\frac{-1}{2}(x-(-2))[/tex]

Simplifying just a hair:

[tex]y-5=\frac{-1}{2}(x+2)[/tex].
