how is the radius and area of a circle proportional

Answers

Answer 1

Answer:

The factor '2 pi' is simply the constant of proportionality between C and R. So the area of a circle is proportional to R2 and pi is the constant of proportionality between the area and the radius of a circle.

Answer 2

Answer: The relationship between the area of a circle and the radius of the circle can be stated as follows: The area of a circle is proportional to the square of the radius.   Written in symbolic notation: A = R 2 RELATIONSHIP 5.1 Area = x (radius) squared OR A = R 2

Answer:

(- 3, 0 ) and (5, 0 )

Step-by-step explanation:

To find the x- intercepts let f(x) = 0 , that is

x² - 2x - 15 = 0

Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (- 2)

The factors are - 5 and + 3 , since

- 5 × 3 = - 15 and - 5 + 3 = - 2 , then

(x - 5)(x + 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 5 = 0 ⇒ x = 5

x + 3 = 0 ⇒ x = - 3

The x- intercepts are (- 3, 0 ) and (5, 0 )

Answer:

a.

Scale Factor = 2

Reason:

Since, B is a scaled copy of A it's corresponding sides must be in proportion with that of A, and that proportion would be its scale factor.

I held their horizontal sides and compared them.

in case of A, the side is 2.5 and in case of B it's 5.

so, 5 divided by 2.5 gets you 2, that is the scale factor.

b.

3, 5 (from left to right)

Solution:

[tex] \boxed{ \mathsf{ \frac{crsp. \: side \: of \: b}{crsp. \: side \: of \: a} = scale \: factor }}[/tex]

this also means

[tex] \boxed{ \mathfrak{crsp. \: side \: of \: b =( scale \: factor) \times \: crsp. \: side \: of \: a }}[/tex]

Scale factor = 2

Using this we'll get the answer to the question marks

The corresponding side to 1.5 is the vertical one in B.

=> corresponding side in B = 2 × 1.5

= 3

(this is the first question mark in order from left to right)

The corresponding side to 2.5 is:

= 2 × 2.5

= 5

c.

53° and 37° (from top to bottom)

Solution:

Scaled shapes have the same angle measures.

Reason:

When we scale two line segments meeting at a point, the lengths of the segments change but they still are part of the same pair of rays making the same angle.

Find the perimeter of the triangle whose vertices are (−4,4), (−4,1), and (−8,−4). Write the exact answer. Do not round.

Answers

Answer:

Step-by-step explanation:

The perimeter of the triangle is [tex]3 + \sqrt{41} + 5\sqrt{5}[/tex] units

How to determine the perimeter?

The coordinates are given as:

(−4,4), (−4,1), and (−8,−4).

Calculate the distance between the vertices using:

[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2[/tex]

So, we have:

[tex]AB = \sqrt{(-4 + 4)^2 + (4-1)^2} = 3[/tex]

[tex]BC = \sqrt{(-4 + 8)^2 + (1+4)^2} = \sqrt{41[/tex]

[tex]AC = \sqrt{(-4 + 8)^2 + (4+4)^2} = \sqrt{80[/tex]

The perimeter is the sum of the side lengths.

So, we have:

[tex]P = 3 + \sqrt{41} + \sqrt{80}[/tex]

Expand

[tex]P = 3 + \sqrt{41} + 4\sqrt{5}[/tex]

Hence, the perimeter of the triangle is [tex]3 + \sqrt{41} + 5\sqrt{5}[/tex] units

Devin owes $26,000 in students loans for college. The interest rate is 8.75% and the loan will be paid off over 15 years. How much will Devin pay altogether?

Answers

Using simple interest, it is found that Devin will pay $60,125 altogether.

The amount paid in simple interest is:

[tex]A = P(1 + rt)[/tex]

In which:

P is the principal.r is the interest rate, as a decimal.t is the time, in years.

In this problem:

Owes $26,000 in student loans, thus [tex]P = 26000[/tex]Interest rate of 8.75%, thus [tex]r = 0.0875[/tex]Paid off in 15 years, thus [tex]t = 15[/tex].

The amount he will pay is of:

[tex]A = 26000[1 + 0.0875(15)][/tex]

[tex]A = 60125[/tex]

Devin will pay $60,125 altogether.

5 years ago, the average age of ishan and his father was 27 years old. If ishan is now 1/3 of his father’s age, how old os ishan now?

Answers

Answer:

9

Step-by-step explanation:

3x9=27

Let the age of son be x.
Thus, age of father is 4x.
After 5 years, their ages will be x+5 and 4x+5 years respectively.
As per the question, we have
4x+5=3(x+5)
⇒4x+5=3x+15
⇒x=10
Age of father will be 4x=4×10=40 years.
Thus when son is 10 years old, father is 40 years

According to the calculations made through cross multiplication, 25% of the muffins were chocolate.

Given that a bakery makes different flavors of muffins, and on Tuesday, the bakery made 30 chocolate muffins and 90 blueberry muffins, to determine what percentage of the sandwiches were chocolate, the following cross multiplication calculation must be performed:

90 + 30 = 100 30 = X 120 = 100 30 = X 30 x 100/120 = X 3000/120 = X 25 = X

Therefore, 25% of the muffins were chocolate.
