Step-by-step explanation: 228/4 = 57, so 57/1 = 57:1.

Answer:

57: 1

Step-by-step explanation:

You take 228 divided by 4 which will give you 57 you do it to this side so you did the same thing to the other which mean you take 4 divided by 4 which is 1 therefore the unit rate is 57: 1

Answer:

1)27.25 feet

2)-0.2774,2.027

3)Domain = All real numbers

Range = y∈R : [tex]y \leq \frac{109}{4}[/tex]

Step-by-step explanation:

The height of the football, h, at time t seconds is modeled by the equation [tex]h(t) = -16t^2 + 28t + 15[/tex]

General quadratic equation : [tex]ax^2=bx+c=0[/tex]

1) Maximum height will be at [tex]\frac{-b}{2a}=\frac{-28}{2(-16)}=\frac{7}{8}[/tex]

To find maximum height Substitute [tex]t = \frac{7}{8}[/tex] in the given equation

[tex]h(t)=-16(\frac{7}{8})^2+28(\frac{7}{8})+15\\h(t)=27.25 feet[/tex]

2)

Substitute h(t)=6

So, [tex]-16t^2+28t+15=6[/tex]

[tex]-16t^2+28t+9=0\\t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\t=\frac{-28\pm \sqrt{28^2-4(-16)(9)}}{2(-16)}\\t=\frac{-28+ \sqrt{28^2-4(-16)(9)}}{2(-16)},\frac{-28- \sqrt{28^2-4(-16)(9)}}{2(-16)}\\t=-0.2774,2.027[/tex]

3)

Domain = All real numbers

Range = y∈R : [tex]y \leq \frac{109}{4}[/tex]

Answer:

The sum of interior angles of given polygon is 900°

Step-by-step explanation:

A regular polygon is a n-sided figure with n sides and the length of all sides is same.

In the diagram, we have a polygon with 7 sides.

The formula given is used to calculate the sum of interior angles of a polygon

[tex]Sum\ of\ interior\ angles = (n-2)*180[/tex]

Here n is the number of sides of polygon

In the given polygon

n = 7

So,

[tex]Sum = (7-2)*180 = 5*180 = 900[/tex]

Hence,

The sum of interior angles of given polygon is 900°

Answer: 1 inch equals 4 feet

Step-by-step explanation:

By an online search, I´ve found that:

The park is 48 ft long.

Caitlin´s drawing is 12 inches long.

To find how much each inch represents, we need to take the quotient between those lengths:

48ft/12in = 4ft/in.

We also can write this amount as:

4 feet per inch.

This means that each inch represents 4 feets.

Then the correct option is the first one:  1 inch equals 4 feet

Answer:

A. (1/2)(4+i)= 2+ (1/2)i

Step-by-step explanation:

The equation 1/2(4+i) = 2+(1/2)i is the transformation if we multiply the complex number 4 + i with 1/2 option first is correct.

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

We have a complex number:

= 4+i

Multiply it by 1/2

[tex]= \rm \dfrac{1}{2}(4+i)\\\\\rm =2+ \dfrac{1}{2}i[/tex]

[tex]\rm \dfrac{1}{2}(4+i) =2+ \dfrac{1}{2}i[/tex]

Thus, the equation 1/2(4+i) = 2+(1/2)i is the transformation if we multiply the complex number 4 + i with 1/2 option first is correct.

Answer:

(8-n=4)/4 click brainliest please and click thanks

Step-by-step explanation:

The mathematical expression which represents the phrase four equals the difference between eight and a number and the result is divided by four is (4 = 8 - x)/4.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

As per the given,

Difference of 8 and a number x = 8 - x

4 equal to 8 - x

4 = 8 - x

Now,

The result is divided by 4

Therefore,(4 = 8 - x)/4

Hence "The mathematical expression which represents the phrase four equals the difference between eight and a number and the result is divided by four is (4 = 8 - x)/4".

The description of the transformation of z on the complex plane gives the quotient is B. scale z by a factor of 1 and rotate it 5 degrees clockwise.

It should be noted that a quotient simply means the number that obtained when division of numbers takes place.

In this case, the description of the transformation of z on the complex plane gives the quotient of 2 = 8cos30° + i sin30° and w = 2cos5° + i sin5° is to scale z by a factor of 1 and rotate it 5 degrees clockwise.
