A cell phone tower has a range of 4 miles. The area covered by the tower is 130.09 km².

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies.

An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure. The square unit, which is frequently expressed as square inches, square feet, etc., is the accepted unit of area.

Given,

A cell phone tower has a range of 4 miles.

Converting miles into kilometer,

1 miles = 1.609

4 miles = 6.437

Answer:

answer is A Step-by-step explanation

Answer:

If you accept a job with a salary of $37,300 and receive a 6% raise after 6 months, your new salary will be $37,300 x 6/100 = $2,238. This is the amount of your raise. To determine your new salary, we can add the raise to your original salary, which gives us:

New salary = $37,300 + $2,238 = $39,538

Therefore, your new salary after receiving a 6% raise will be $39,538.

Step-by-step explanation:

The linear equation can be written as:

y = -5*(x + 3) - 4

And its graph can be seen at the end of the answer.

Here we want to graph a line with a slope of -5 that contains the point (-3, -4).

Particularly, for a line with a slope a and a known point (h, k) can be written in the point-slope form as:

y = a*(x - h) + k

So our line can be written as:

y = -5*(x + 3) - 4

Now let's graph it. To graph the line we need to know two points on the line. We already know one that is (-3, -4)

Let's find another, if we evaluate the line in x = 0 we will get:

y = -5*(0 + 3) - 4

y = -5*3 - 4

y = -15 + 4

y = -19

Then the linear equation also contains the point (0, -19), now just let's graph the two known points and connect them with a line. The graph of the g can be seen below.

The measure of distance RS, if The sides QU = 140 m, US = 115 m, TU = 104.55 m, rounding to the nearest hundredth of a meter, is 200 m.

Triangles are basic three-sided polygons with three internal angles. It is one of the basic geometric shapes, symbolized by the symbol, and has three vertex connections.

Given:

The sides QU = 140 m, US = 115 m, TU = 104.55 m

As you can see, the triangle QRS and triangle QTU are similar, thus the ratio of their sides will be equal,

QU / QS = TU / RS

The length of side X in the simplest radical form exists 22/√3.

Trigonometry is the study of angles and the angular connections between figures in two and three dimensions. The trigonometric functions that make up trigonometry are cosecant, cosine, cotangent, secant, sine, and tangent. These are also known as the circle functions.

Trigonometric Identities are equality statements involving trigonometry functions that hold true for all values of the input variables in the equation. The side length and angle of a triangle are both subject to a variety of distinctive trigonometric identities.

The triangle is right angled, therefore we can apply trigonometry :

To obtain the value of X which is the hypotenuse :

Using trigonometric identities,

Cosθ = adjacent / hypotenuse

Substitute the values in the above equation, we get

Cos 30 = 11 / X

√3/2 = 11 / X

simplifying the above equation, we get

√3 / 2 × X = 11

X = 11 ÷ √3 / 2

X = 11 × 2 / √3

X = 22/√3

Therefore, the length of side X in the simplest radical form is 22/√3.

A) The population P after t hours as a function of t p(t) = 820 [tex]e^{0.3465t}[/tex]  k = 0.3465 , B)The population after 8 hours of

bacteria is p(8) = 13120 , C) The population to reach 2450, time will be t= 3.15 hour

A linear relationship between two amounts or variables is shown by proportionality. Both quantities increase in size when one doubles, and both decrease in size when one drops to a tenth of its original amount.

It is given that  

dp/dt ∝ p

dp/dt = kp

dp/p = kdt

log p = kt +c

p(t) = c[tex]e^{kt}[/tex]

when t = 0 then p = 820

therefore c = 820

p(t) = c[tex]e^{kt}[/tex]

when t = 2hours then p = 1640

1640 = 820[tex]e^{2k}[/tex]

2k = ln2

k = ln2/2

k = 0.3465

p(t) = 820[tex]e^{0.3465t}[/tex]  bacteria

B)

when t = 8hours

p(8) = 820[tex]e^{0.3465* 8}[/tex]

p(8)= 820*16

p(8) = 13120 bacteria

c)

when p = 2450 then t = ?

2450 = 820[tex]e^{0.3465t}[/tex]

2450/820 = [tex]e^{0.3465t}[/tex]

t =1.0945/0.3465

t= 3.15hours

Thus

A) The population P after t hours as a function of t p(t) = 820 [tex]e^{0.3465t}[/tex]  k = 0.3465 , B)The population after 8 hours of

Answer:

y = -x + 11

Step-by-step explanation:

y = mx + b

m is the slope and b is the y-intercept so m = -1

y = -x + b

Now substitute x = 8 and y = 3:

3 = -8 + b

b = 11

Thus the final equation is y = -x + 11.

Answer: The function would have a minimum value because the least you will ever have is 0$. It cannot go below 0, so that is the minimum. However, depending on how much time has passed, the maximum amount of money you have can change. It can always go up more, so there is no set maximum.

What does division of fractions mean?

A fraction is divided into additional equal pieces when it is divided into fractions. For instance, if you had three-fourths of a pizza remaining and divided each slice into two pieces, you would have received six slices, which would be equivalent to six-eighths of the entire pizza.

Top expression = 5/8 + 3/4

                          = (5 + 6)/ 8 = 11/8  ( 8 is the lcm of 4 and 8 )

Bottom expression = -2/3 - 5/6

                                = (-4 - 5)/ 6

                                = -9/6 = -3/2

Top expression/ Bottom expression = (11/8)/ (-3/2  )

                                                            = - (11/8) * (2/3)

3. y int= 6

4. m=6

5. y=-2x-8

Step-by-step explanation:

3.  since the y intercept is when x=0 the table shows the y=6.

4.  to find m we use          change in y/change in x

the change in y is 6 because 6-0=6

change is x is 1 because 0--1=1

6/1=6

5.  y=mx+c

c is y intercept thus c= -8

m is function rate/ gradient of the line = -2

this is because:

change in y= -8--2=-6

change in x= 0--3=3

-6/3= -2

thus y=-2x-8

Answer:

In the third quadrant, the sine of an angle is negative, so the angle itself must be between 180 and 270 degrees. This means that the cosine of the angle, and therefore the cosine of half the angle, is also negative.

To find the exact value of the cosine of half the angle, we can use the double angle formula for cosine, which states that cos(2A) = 1 - 2sin^2(A). Since the sine of half the angle is sin(B/2) = sqrt((1 - cos(B))/2), we can plug this into the double angle formula to get:

cos(B/2) = sqrt(1 - cos(B))/sqrt(2) = sqrt((1 - (-1/3))/2) = sqrt(4/6)/sqrt(2) = sqrt(2/3)/sqrt(2) = sqrt(1/3)

Therefore, the value of cos(B/2) is sqrt(1/3), which is positive because B/2 is between 0 and 90 degrees. The exact value of the cosine of half the angle B in the third quadrant is sqrt(1/3).

Shape would the resulting distribution have very symmetric distribution with a single peak was found to be the corrected long-jump distances in centimeters distribution's shape.

In common parlance, the term "symmetry" describes a sense of lovely proportion and balance. A more exact meaning of "symmetry" can be found in mathematics, where it typically refers to an object that is unaffected by certain transformations like translation, reflection, rotation, or scaling.

Given,

100 cm = 1 m

Xₙ = 557.3 cm

Divide each centimeter number by 100 to convert the corrected long jump distances from centimeters to meters.

A very symmetric distribution with a single peak was found to be the corrected long-jump distances in centimeters distribution's shape.

The distribution's structure is unaltered when each value in the data is divided by 100 since there are no changes to the relationships between any two pieces of data.

Since there is just one peak in this example, the corrected long-jump distances in meters distribution likewise has an almost symmetric form.
