Answer:

Step-by-step explanation:

1). Let the circumference C and area A of the circle are proportional,

   C ∝ A

   C = kA

   Here k = proportionality constant

   k = [tex]\frac{C}{A}[/tex]

   From the given table,

   For C = 25 cm, A = 50 cm²

   Then the value of k = [tex]\frac{25}{50}[/tex]

                                  k = [tex]\frac{1}{2}[/tex]

    For C = 50 cm, A = 201 cm²

    k = [tex]\frac{50}{201}[/tex] ≈ [tex]\frac{1}{4}[/tex]

    In both the cases proportionality constant is giving the different values.

    Therefore, Circumference and Area of the circular objects are not proportional.

2). If A = [tex]\frac{1}{2}\times r\times C[/tex]

    Then this equation will be true for all the values of r and C given in the table.

    For r = 4 cm and C = 25 cm

    A = [tex]\frac{1}{2}\times 4\times 25[/tex] = 50 cm²

    For r = 8 cm and C = 50 cm

    A = [tex]\frac{1}{2}\times 8\times 50[/tex]

    A = 200 cm²

    True for all values of 'r' and 'C'.

Answer:

[tex]4d^2-12d+9[/tex]

Step-by-step explanation:

Okay, so lets break this problem down. We are given two binomials to multiply together. The simplest way to get our answer is by using the F.O.I.L method. This is done by the following:

F:  First

O: Outer

I: Inner

L: Last

To say simply, the first term in the first parenthesis or 2d will be multiplied the first term in the second parenthesis 2d.

Here are the steps:

[tex](2d-3)(2d-3)\\2d*2d=F\\2d*-3=O\\-3*2d=I\\-3*-3=L\\Now:\\2d*2d=4d^2\\2d*-3=-6d\\-3*2d=-6d\\-3*-3=9\\$4d^2-6d-6d+9\\Combine Terms\\4d^2-12d+9[/tex]

I would be happy to help you again in the future, and hope that this provided some clarification for you. Have a nice day! :D

Answer:

38 degrees

Step-by-step explanation:

If the line is tangent that means it forms a 90 degree angle. The angle measure of the inside of a triangle is equal to 180 degrees. If you add 52 and 90 you get 142. Subtract this amount from 180 and you will get the measure of m TMS

Answer:

b=[tex]\sqrt{95}[/tex]

Step-by-step explanation:

a^2+b^2=c^2

7^2+b^2=12^2

49+b^2=144

b^2=95

b=[tex]\sqrt{95[/tex]

Answer:

(2, 2)

Step-by-step explanation:

In this case, elimination would be the most efficient means of solving.

Simply, add the two equations, and you will be left with only one variable to solve for. (In this case y) You are then able to take your solution and plug it into an equation and solve for x, therefore giving you their intercept.\

5x + 10y = 30

+

-5x + 15y = 20

(x's cancel) 25y = 50

25y = 50

y = 2

5x + 10(2) = 30

5x + 20 = 30

5x = 10

x = 2

The solution to this equation is (2, 2)

Answer:

-[tex]\sqrt{5}[/tex], or about -2.24 in decimal form

Step-by-step explanation:

Add -3 and 2 and keep the [tex]\sqrt{5}[/tex]. -3+2 is -1, so the answer is -[tex]\sqrt{5}[/tex].

Answer:

x= 10/3

Step-by-step explanation:

=> -10+x1.5= -5

=> x1.5= -5 +10

=> x1.5= 5

=> x= 5/1.5

=> x= 10/3

Answer: The first option (A)

Step-by-step explanation:

Answer:

It is A.

Step-by-step explanation:

AC=DF, AB=DE

Answer:

DF= 9.8

Angle F= 42.6 degrees

Angle E= 23.1 degrees

Step-by-step explanation:

so for the sides we can use the pythagorean theorem

23^2+b^2=25^2

   23 squared is 529 and

   25 squared is 625

529+b^2=625

    subtract 529 from both sides

b^2=96

    the square root of 96 is ~9.8

b=9.8

To find the angles you use sin, cos, or tan. Now that we know all three sides it doesn't matter which one you use so... pick your favorite.

sinf=23/25

f= ~66.9 degrees

tane= 23/25

e= ~23.1

Answer:thanks for the points I needed them

Step-by-step explanation:

the terms of geometric sequence are 3, -15, 75

given,

1st term (a) = 3

second term (t2)=-15

common ratio (r) = t2/t1

=-15/3

=-5

then

t13= ar^n-1

=3×(-5)^13-1

=3×244140625

=3×244140625

=732421875.

The [tex]13^{th}[/tex] term of the geometric sequence is - 732421875.

A geometric sequence is given ; 3 , -15 , 75....

We have to find the [tex]13^{th}[/tex]  term of the geometric sequence.

What is the formula for calculation of nth term of geometric Sequence ?

The formula for calculation of nth term of geometric progression is [tex]a_{n}[/tex] = [tex]a_{1}[/tex] × [tex](r)^{n-1}[/tex] where r is the common ratio of geometric sequence.

Given geometric sequence is 3 , -15 , 75....

and

Common ratio is r.

i.e., r = -15 ÷ 3 = -5

∵ [tex]n^{th}[/tex] term of a geometric sequence is given by  ;

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] × [tex](r)^{n-1}[/tex]  

where [tex]a_{1}[/tex] is the first term.

So,

[tex]13^{th}[/tex] term of the geometric sequence will be ;

[tex]a_{13}[/tex] =  3 × [tex](-5)^{12}[/tex]

[tex]a_{13}[/tex]   =  - 732421875

Thus ,  the [tex]13^{th}[/tex] term of the geometric sequence is - 732421875.
