The area of a circle is 201cm² . what is the diameter ?

Answers

Answer 1

The answer is 16 cm approx.

Diameter= 2[tex]\sqrt{a/pi}[/tex]

=>2[tex]\sqrt{201 / 22/7}[/tex]

=>2[tex]\sqrt{201*7/22}[/tex]

=>15.997.......

=> 16 approx

Hope this helps you!!

Answer 2

Answer:

The diameter of the circle  is 16

Step-by-step explanation:

[tex]\pi = 3.14[/tex]

Area = [tex]\pi r^{2}[/tex] you will have to use this formula to find the radius

[tex]\pi r^{2} = 201[/tex]   =   [tex]3.14r^{2}=201[/tex] (divide 3.14 into both sides)

[tex]\frac{3.14r^2}{3.14} = \frac{201}{3.14}[/tex]   cross out 3.14 leaves you with [tex]r^2[/tex]  and divide 201/3.14= 64.01

[tex]r^2 = 64.01\\r = \sqrt{64.01}\\r = 8[/tex]  square root 64.01 which equals 8

Diameter = [tex]2r[/tex]    2(8) = 16

To check answer use Area formula [tex]\pi (8)^{2}[/tex] = 201. 0619298

A sequence is defined by the formula f(n+1)=f(n)−3. If f(4)=22, what is f(1)? 10 13 31 34

Answers

Answer:

C:31

Step-by-step explanation:

Considering the given recursive function, it is found that the value of f(1) is of f(1) = 31.

What is the definition of the recursive function?

It is given by:

f(n + 1) = f(n) - 3.

Which means that each term is the previous term subtracted by 3, hence:

f(4) = 22, f(3) = 25, f(2) = 28, f(1) = 31.

a. P= 29.95 + 2.95

P= 29.95 + 0.05m +2.95
d. P= (29.95 + 0.05)m +2.95. What equation should I use?

Answers

Answer:

[tex]P=29.95+0.05m+2.95[/tex]

Step-by-step explanation:

The monthly plan costs starts at $29.95, so we're not changing that.

For each monthly plan, we have to pay a tax of $2.95, so we're not changing that.

If we go over 1,000 minutes, we have to pay $0.05 for every minute we go over, and with the fact that [tex]m[/tex] represents each minute over 1,000, we're going to have to represent minutes over 1,000 as [tex]0.05m[/tex] in our equation.

Set up your equation:

[tex]P=29.95+0.05m+2.95[/tex]

Which expression could be used to represent a 45% increase? (Question 9)

Answers

Answer:

Options (A) and (B)

Step-by-step explanation:

Question (9)

Let a number = x

45% increase in the given number will be = x + (45% of x)

                                                                     = x + [tex]\frac{45x}{100}[/tex]

                                                                     = x + 0.45x

                                                                     = x(1 + 0.45)

                                                                     = 1.45x

Therefore, there will be the two expressions,

A). 1.45x

B). x + 0.45x

Options (A) and (B) will be the correct options.

Evaluate the function f(x)=6x+2 at the given values of the independent variable and simplify.
a. f(8) b. f(x+6) c. f(−x)
. f(8)= (Simplify your​ answer.)

Answers

[tex]f(x) = 6x+2[/tex]

A.

To evaluate f(8), we substitute x with 8 in our expression.

[tex]f(8) = 6*8 + 2\\f(8) = 48 +2\\f(8) = 50[/tex]

Answer: f(8) = 50

B.

To evaluate f(x+6), we do the same but substitute x with x+6 instead.

[tex]f(x+6) = 6(x+6) + 2[/tex]

Expand the parenthesis by multiplying 6 with x and 6.

[tex]f(x+6) = 6x + 6*6 + 2\\f(x+6) = 6x+36+2\\f(x+6) = 6x+38[/tex]

Answer: f(x+6) = 6x + 38

C.

Again, we're doing the same thing, just substituting x with -x.

[tex]f(-x) = 6 * (-x) + 2\\ f(-x)=-6x+2[/tex]

Answer: f(-x) = -6x+2

Answer:

_____________________________________________

[tex] \longmapsto \: f(x) = 6x + 2[/tex]

_____________________________________________

A. [tex]f(8) = 6(8) + 2 = 48 + 2 = \boxed{ 50}✓[/tex]

_____________________________________________

B. [tex]f(x + 6) = 6(x + 6) + 2 \\ = 6x + 36 + 2 \\ = \boxed{ 6x + 38}✓[/tex]

What is the relationship between Za and Zb?

Answers

Answer: B

Step-by-step explanation:

∠a and ∠b are complementary angles. Complementary angles are two angles adjacent to each other that add up to 90°. We know this is true because of the 90° angle that is labelled.

Vertical angles are not adjacent to each other. They are across from each other, connected by the angle. They are equal in angles. It is clear that ∠a and ∠b are not equal in angles. Therefore, they are complementary angles.

The midpoint of AB is M(2, -1). If the coordinates of A are (1,6), what are the
coordinates of B?

Answers

Answer:

work is attached and shown

The coordinate of point B will be (3, -8) for the given line segment.

What are coordinates?

A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).

Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.

For example (5,3) here 5 will be for the x and 3 will be for the y.

Another example is (9,0) here 9 is for x and 0 is for y.

Given the line segment, AB

If the M(2, -1) is the midpoint of A(1,6) and B(x,y)

Then,

(1 + x)/2 = 2 ⇒ x = 3

(6 + y)/2 = -1 ⇒ y = -8

So B(3, -8).

Hence "The coordinate of point B will be (3, -8) for the given line segment".

Which number line shows the points −12/5 and –2.8?

Answers

The answer will be a

The number line that shows the points −12/5 and –2.8 is Option A.

What is a number line?

Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever. Some will have a defined beginning and end. It refers to those as closed number lines. Number lines might be alternatively left empty or blank. A number ladder is a vertical number line.

The given numbers are: −12/5 and –2.8

As we can re-write -12/5 in decimal form= -2.4

Now, we need to mark the number on the number line.

As the number -2.4 lies between -2 and -3 on the left side of zero.

and, -2.4 lies between -the numbers 2.5 and -3.0 on the left side of zero.

Simplify 12edf – 13def. State a property that you can use.

Answers

Answer:

-def. In multiplication, the order doesn't matter.

Step-by-step explanation:

A crucial property you can use to simplify this is the fact that, in multiplication, order doesn't matter.

3 * 2 = 6

2 * 3 = 6

5 * 2 * 3 = 30

2 * 3 * 5 = 30

3 * 2 * 5 = 30

Thus,

edf, or

e * d * f

is the same as def,

d * e * f

e * d * f = d * e * f

edf = def

Thus, 12edf is the same as 12def. We can put this in our expression:

12edf - 13def

12def - 13def

Now, we can see that this will equal -1def or -def

12def - 13def

-1def

-def

Answer: -def. In multiplication, the order doesn't matter.
