Rewrite each geometry formula using function notation. Use the same variables as the formula in your function. Evaluate each function when r=5 feet. Do not round; write answers in terms of pi, if necessary. Explain the meaning of the result.

a. Diameter, d=2r
The formula using function notation is _______; The value when r=5 is _______; The diameter of the circle is ______ feet when the radius is ________ feet.

b. Area, A=pi x r^2
The formula using function notation is _______; The value when r=5 is _______; The area of the circle is ______ feet when the radius is ________ feet.

c. Circumference C=2 x pi r

The formula using function notation is _______; The value when r=5 is _______; The Circumference of the circle is ______ feet when the radius is ________ feet.

Answers

Answer:

A) d(r) = 2r

Value when r = 5 is 10 ft.

diameter is 10 ft when the radius is 5ft

B) A(r) = πr²

Value when r = 5 is 25π ft²

Area is 25π ft² when radius is 5 feet

C) C(r) = 2πr

Value when r = 5 is 10π

Circumference is 10π when radius is 5 feet

Step-by-step explanation:

A) Using function notation, since d = 2r

d(r) = 2r

d(5) = 2(5)

d(5) = 10 feet

This means that the diameter is 10 ft when the radius is 5ft

B) Area = πr²

In function notation, its;

A(r) = πr²

When radius is 5 feet,

Area is; A(5) = π(5²) = 25π

It means Area is 25π ft² when radius is 5 feet

C) Circumference is 2πr

In function notation, it's;

C(r) = 2πr

When r = 5 feet,

Circumference is;

C(5) = 2π(5)

C(5) = 10π

Giovanni went to the Lowe’s looking for supplies. He bought three pounds of cement for $27.75 per pound. A plant for $12.58. He paid $8.99 is sales taxes. How much did he pay in total at Lowe’s?

Answers

Step-by-step explanation:

Hey there! Let's break this answer down.

1. If he bough 3 pounds of cement for $27.75 each, that 3x27.75, which is $83.25. So he spent $83.25 on cement.

2. Next, add $12.58 for the cost of the plant to $83.25, which $95.83.

3. Finally, he paid $8.99 for the sales tax. When adding that to $95.83, we get $104.82.

So, his total was $104.82.

Have a great day!

Answer:

104.82

1Step-by-step explanation:

27.75 times 3 equals 83.25 plus 12.58 equals 95.83 then add 8.99 which is $104.92

Convert 3x - 5y = 30 into Slope-Intercept Form

The given equation can be rearranged to equate both side of the equation and thus we can get equivalent on both side as 6 (2y-3) = 6 (2y-3). Therefore, y can have any values from 0.

What are algebraic equations?

Algebraic equations are expression used to represent the relation between two values by some letters or alphabets whose values are not specified in the equation.

In general, the letters x and y are used in the algebraic equations. They can linear or non-linear equation. By rearranging this equations we can determine the values of x and y.

Given the expression 12 y - 18 = 6 (2y - 3). From the left hand side, divide the part 12 y - 18 by 6. Thus we obtain the expression equivalent to the right hand side as 6 (2y - 3).

Therefore, 6 (2y - 3) = 6 (2y - 3). Which means both sides are equal and have equal value of y. means y can have any values from zero since all the terms including y is zero both side.

Thus, giving any value to y will always remains the same equation.

Be sure to address counterclaims in your essay and include reasons and evidence to support your argument.(this is the essay)Imagine you are part of the colonies in 1765 the stamp act was just enacted. Your enraged so you go along with the constant chant of "Taxation without representation is tyranny". Then people start talking about freedom an Escape from Britain not long after the Revolutionary War is happening. Once 7 years passed the war is over.declaring independence was justified especially after the Intolerable Acts. However the war may had been avoided if they just let them have their freedom in instead of having a war that lasted 7 years. yet the whole thing could have been avoided, if the British did not keep such a tight hold on the colonists, gave them representation in parliament, and gave them the birthrights they desperately wanted. A counterclaim may be that the war was justified and declaring independence was not. The British were the first ones to fire sparking the war therefor making it justified. may be considered Declaring independence was not justified given they could have stayed and then everything would have stayed the same.however looking at the details you can see that declaring independence was very much justified particularly because they wanted to get away from the Intolerable Acts and the Boston Massacre and they had every right to. The war COULD have been avoided if they had just recognized american as independence it would have never happened.in conclusion: ideazalso ill give you 50 points just cause im nice :) all functions are relations but why not all relations are functions 2/3 of 1/2 What is the answer.
