For this case we have that by definition, the circumference of a circle is given by:

[tex]C = \pi * d[/tex]

Where:

d: It is the diameter of the circle

We have as data that:

[tex]C = 6 \pi[/tex]

So:

[tex]6 \pi = \pi * d[/tex]

Thus, the diameter of the circle is 6, therefore the radius is 3.

The area of a circle is given by:

[tex]A = \pi * r ^ 2[/tex]

Where:

r: It is the radius of the circle

[tex]A = \pi * 3 ^ 2\\A = 9 \pi[/tex]

Answer:

Option B

Answer:

9π in. ²

Step-by-step explanation:

The circumference of a circle is diameter times pi.

To find the area of a circle, you multiply the radius by itself, and the product by pi.

Diameter (6 in.) divided by two equals the radius (3 in.).

3 x 3 = 9 in.²

Then multiply by pi to get, 9π in.²

Step-by-step explanation:

Using the rule of exponents

• [tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex]

• [tex]a^{-m}[/tex] ⇔ [tex]\frac{1}{a^{m} }[/tex]

[tex](\frac{1}{9}) ^{a+1}[/tex] = [tex]9^{-(a+1)}[/tex] = [tex]3^{-2(a+1)}[/tex]

and right side

= [tex]3^{4(a+1)}[/tex] × [tex]3^{3(2-a)}[/tex]

Hence

[tex]3^{-2a-2}[/tex] = [tex]3^{4a+4}[/tex] × [tex]3^{6-3a}[/tex]

[tex]3^{-2a-2}[/tex] = [tex]3^{a+10}[/tex]

Equating exponents on both sides gives

a + 10 = - 2a - 2 ( add 2a to both sides )

3a + 10 = - 2 (subtract 10 from both sides )

3a = - 12 ( divide both sides by 3 )

a = - 4

Step-by-step explanation:

Answer:

Required probability is 0.3025.

Step-by-step explanation:

Given that probability of landing heads up in a toss of bent coin = 0.55

Then probability of getting head in 1st toss = 0.55

2nd toss is independent of the first toss.

Then probability of getting head in 2nd toss = 0.55

Hence probability of getting head in two tosses of the coin = (0.55)(0.55) =0.3025

Hence required probability is 0.3025.

Answer:

0.3025

Step-by-step explanation:

Given:

The probability of landing heads P(h) = 0.55  

The probability of landing heads when the coin is tossed again is 0.55 as both the events are independent and we are given the probability of heads P(h) = 0.55

So,

The probability of getting 2 heads in a row=0.55*0.55

                                                                   =0.3025

Answer:

$97.75

Step-by-step explanation:

since its 15% off, the price would be 85% of its original price.

85/100 x $115 = $97.75

Jeanine paid $97.75 for the hiking boots after receiving a 15% discount on the regular price of $115.00. The discount was calculated by converting the percentage to a decimal and multiplying it by the regular price, then subtracting it from the regular price.

Jeanine bought hiking boots with a 15% discount off the regular price of $115.00. To calculate how much Jeanine paid for the hiking boots, we first need to find the amount of the discount. The discount amount is calculated as 15% of the regular price.

The calculation for the discount is as follows:

Convert the percentage to a decimal by dividing by 100: 15% / 100 = 0.15.

Multiply the regular price by the decimal: $115.00  imes 0.15 = $17.25.

Subtract the discount from the regular price: $115.00 - $17.25 = $97.75.

Thus, Jeanine paid $97.75 for the hiking boots.

Answer:

Step-by-step explanation:

The value of the function f(x) at x=a can be determined by substituting a instead of x into the function expression.

1. When x=-1, then

f(-1)=2\cdot (-1)^3-3\cdot (-1)^2+7=-2-3+7=2.

2. When x=1, then

f(1)=2\cdot 1^3-3\cdot 1^2+7=2-3+7=6.

3. When x=2, then

f(-1)=2\cdot 2^3-3\cdot 2^2+7=16-12+7=11.

Answer:

f(-1)=2

f(1)=6

f(2)=11

Step-by-step explanation:

The given function is [tex]f(x)=2x^3-3x^2+7[/tex]

Substitute x = -1 to find the value of f(-1)

[tex]f(-1)=2(-1)^3-3(-1)^2+7\\\\=-2-3+7\\\\=2[/tex]

Thus, f(-1)=2

Substitute x = 1 to find the value of f(1)

[tex]f(1)=2(1)^3-3(1)^2+7\\\\=2-3+7\\\\=6[/tex]

Thus, f(1)=6

Substitute x = 2 to find the value of f(2)

[tex]f(2)=2(2)^3-3(2)^2+7\\\\=16-12+7\\\\=11[/tex]

Thus, f(2)=11

the measure of those two angles equals 180 since it forms a line

so you add up both angles and set that equal to 180.

(I'll use x as the variable but it's still the same answer)

5x-3+9+x=180

combine like terms

6x+6=180

subtract 6

6x=174

then divide by 6

x=29

To find the value of angle H in a triangle, you subtract the sum of the other two angles from 180. This is based on the triangle angle theorems which state that the sum of the angles in a triangle always equals 180 degrees.

In triangle angle theorems, the sum of the angles of a triangle always add up to 180 degrees. If you need to find the value of angle H in your triangle, you'll need to know the measures of the other two angles. For example, if one angle measures 60 degrees and the other measures 50 degrees, you would subtract the sum of these two angles from 180 to find the value of angle H.

Sum of angles in triangle = 180 degrees

So, Angle H = 180 - (60 + 50) = 70 degrees

Answer:

if it has two real repeated solutions then t=-9/8

if it has two real distinct solutions then t>-9/28

Step-by-step explanation:

Given:

tx^2+3x-7=0

Also above equation has two real solutions

Now what can deduced about the value of t?

For any quadratic equation "ax^2 +bx +c=0" the solution is given by the quadratic formula

x= [tex]\frac{-b+/-\sqrt{b^{2}-4ac } }{2a}[/tex]

The part under the square root i.e b^2 - 4ac is called the discriminant and it decides whether the equation will have 1 solution, 2 solution or no solution.

if discriminant is negative, i.e. <0 then equation will have no real solution

if discriminant is zero, i.e. =0 then equation will have two repeated real solution

if discriminant is positive, i.e >0 then equation will have two real distinct solution

As given equation has two real solutions:

if they are distinct then

b^2-4ac>0

Putting values of a=t, b=3, c=-7 in above we get,

9+28t>0

28t>-9

t>-9/28

if they are repeated then

b^2-4ac=0

Putting values of a=t, b=3, c=-7 in above we get,

9+28t=0

28t=-9

t=-9/28!

bearing in mind that the sum of all interior angles in a polygon is

180(n - 2)    n = number of sides in the polygon

a DECAgon, DECA=10, has 10 sides, and thus the sum of all its interior angles is 180(10 - 8) = 1440.

[tex]\bf 156+135+147+160+116+150+150.2+119.2+146.6+z=1440 \\\\\\ 1280+z=1440\implies z=1440-1280\implies z=160[/tex]

Final answer:

The angle z in the decagon is calculated by subtracting the sum of the given angles from the total interior angle sum of a decagon, which is 1440°. The measure of angle z is 159.8°.

Explanation:

In geometry, the sum of the interior angles of an n-sided polygon is given by the formula (n - 2) × 180°. For a decagon, which is a 10-sided polygon, this sum is (10 - 2) × 180° = 8 × 180° = 1440°. To find the measure of the unknown angle z in the decagon with the given angle measurements, we can subtract the sum of the known angles from this total.

First, let's add up the given angles: 156° + 135° + 147° + 160° + 116° + 150° + 150.2° + 119.2° + 146.6° = 1280.2°. Now, subtract that sum from the total sum of the angles for a decagon: 1440° - 1280.2° = 159.8°. Therefore, the measure of angle z is 159.8°.

The 3rd sequence could not be described by the following recursive definition tn+1 = tn + 6

Step-by-step explanation:

* Lets revise the recursive formula

1. Determine if the sequence is arithmetic (Do you add, or subtract, the

  same amount from one term to the next?)

2. Find the common difference. (The number you add or subtract.)

3. Create a recursive formula by stating the first term, and then stating

   the formula to be the previous term plus the common difference.

   a1 = first term;

   an+1= an + d

- Where:

# a1 = the first term in the sequence

# an = the nth term in the sequence  

# an+1 = the term after the nth term  

# n = the term number

# d = the common difference.

* Now lets solve the problem

∵ tn+1 = tn + 6

∴ d = 6 ⇒ common difference

he should round to the hundredths place so 17.32

Answer:

Karen should round to hundredth place.

Step-by-step explanation:

We are given that Kalen is trying to find the average of three measurements.

The measurements are 13.8, 15.64, and 22.51.

Now we are given that He adds the  numbers and divides by three. The result on the calculator shows 17.3167

Now we are asked Where should Kalen round the final answer.

Since the values in the given data is upto hundredth place

So, we are supposed to round the final answer to hundredth place.

So, final answer after round off = 17.32

Hence Karen should round to hundredth place.

To find the infinite geometric sum of the series 80 + 10 + 1.25 + ..., use the formula S = a / (1 - r), with 'a' as the first term and 'r' as the common ratio. Apply the significant figures principle for accurate rounding when approximating to a certain number of decimal places.

The student's question involves finding the infinite geometric sum of the series 80 + 10 + 1.25 + .... To determine this sum, we use the formula for the sum of an infinite geometric series, S = a / (1 - r), where 'S' is the sum of the series, 'a' is the first term, and 'r' is the common ratio between terms. In this series, 'a' is 80, and the common ratio 'r' can be found by dividing the second term by the first term, which is 10/80 or 1/8.

Plugging the values into the formula gives us S = 80 / (1 - (1/8)) which simplifies to S = 80 / (7/8) = 80 * (8/7) = 640/7. Calculating this yields an infinite sum which can be approximated to decimal places as needed.

For precise calculations, especially when rounding to a certain number of decimal places or significant figures, the rules of significant figures must be followed. As the sample information shows, if a number in the tenths place is to be dropped and it's greater than 5, we round up to ensure the final value adheres to the significant figures principle, consistently providing a more accurate and professional result.
