Find The Area Of The Shaded Region. Use 3.14 As An Approximation.

Answers

Answer 1

Answer:

shaded area = 113.64 cm²

Step-by-step explanation:

To find the shaded area, subtract the area of the circle from the area of the triangle.

Area of a triangle = 1/2 x base x height

⇒ area of triangle = 1/2 x 25 x 21.4 = 267.5 cm²

Area of a circle = [tex]\pi r^2[/tex] (where r is the radius)

From inspection, we can see that the diameter of the circle = 14 cm

Therefore, as the diameter = 2r, then r = 14 ÷ 2 = 7 cm

⇒ area of circle = 3.14 x 7² = 153.86 cm²

Shaded area = area of triangle - area of circle

⇒ shaded area = 267.5 - 153.86 = 113.64 cm²

Step-by-step explanation:

A cell phone company conducted a survey to determine if customers were satisfied with their cell phone service. The survey sample consisted of all customers who had contacted the company within the past year and who agreed to participate. Of the 420 customers surveyed, 65% reported that they were not satisfied with their service.

Which statement about this sample is true?


A Exactly 65% of all customers are not satisfied with the cell phone service.

B The sample includes all customers who made complaints to the company within the last year, and therefore is representative of the population. ,

C The sample might not be representative of the population because, in general, satisfied customers have no reason to contact the company.

D No generalizations can be made from this sample because the sample size is too small.

Answers

The statement that is true about the given sample is that;

B. The sample includes all customers who made complaints to the company within the last year, and therefore is representative of the population. ,

Sample Statistics Interpretation

We are given;

Sample size; n = 420

Sample proportion; p^ = 65%

Now, from the sample size and proportion, we can say that;

Exactly 65% of the surveyed customers were not satisfied with the cell phone service. Now, this only represents those surveyed and not the entire population. Thus it is not exactly 65% of all customers that are not satisfied with the cell phone service.

Option B is correct because the 420 customers surveyed is a sample from the population of all their customers within the last year.

Answer:

The length of the missing leg is six

Step-by-step explanation:

Assuming that this is a right triangle, you can use the Pythagoras theorem

12^2+x^2=sqrt180^2

144+x^2=180

x^2=36

x=6

Therefore, the length of the missing leg is six.

Answer:

Taking the above as a right angled triangle...

Pythagoras' rule can be applied to get the Missing side.

It goes...

Hyp² = Opp² + Adj²

Which translates to Hypotenuse, Opposite and Adjacent respectively.

Hyp = √180

Opp= 12

So we're missing Adj

Making adj the subject.

Adj = √ Hyp² – Opp²

= √[(√180)² – (12)²

= √ [ 180 – 144]

= √36

Adj = 6ft.

Steve manages a skate park and he has been analyzing the attendance data. Steve finds that the number of visitors increases exponentially as the temperature increases, and this situation is represented by the function f(x) = 5x. Steve also finds a linear equation that models the number of people who leave the park early depending on the change in temperature, and it is represented by g(x) = −x 6. The graph of the two functions is below. Find the solution to the two functions and explain what the solution represents.

Answers

Answer:

See the Analysis

Step-by-step explanation:

Solution: From the problem

[tex]\left \{ {{f(x)=5^{x} } \atop {g(x)=-x+6}} \right.[/tex]

From 1 and 2

[tex]5^{x}=-x+6\\ x=1, y=5[/tex]

It means that the temperature is leaving as many people as it is increasing.

Use the function: g(x) = (x + 2)(x - 1)(x - 2) a) Find the zeros of the function. b) Find the y-intercept of the function.

Answers

Answer:

The zeros are -2, 1, and 2

Step-by-step explanation:

You have to set each individual equation equal to zero.

ex: (x+2) x+2=0 move the number to the right hand side to get x alone x=-2

as for the y intercept I don't know

Answer:

see explanation

Step-by-step explanation:

g(x) = (x + 2)(x - 1)(x - 2)

To find the zeros let g(x) = 0 , then

(x + 2)(x - 1)(x - 2) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 1 = 0 ⇒ x = 1

x - 2 = 0 ⇒ x = 2

The zeros are x = - 2, x = 1, x = 2

To find the y- intercept substitute x = 0 into g(x)

g(0) = (0 + 2)(0 - 1)(0 - 2) = 2(- 1)(- 2) = 2 × 2 = 4

The y- intercept is 4 or (0, 4 )

The theater group sold adult and student tickets for the play. They sold a total of 560 tickets. Each adult ticket was $8 and each student ticket was $3.50. The group took in a total of $3166. How many of each type of ticket was sold for the play?

Answers

Answer:

268 adult and 292 student tickets sold

Step-by-step explanation:

a = number  adult tickets sold

s =  number student tickets sold

a + s = 560

8a + 3.50s = 3166

a = 268 adult tickets

s = 292 student tickets

help me with angle sum theorem please what is y

Answers

Answer:

y = 140

Step-by-step explanation:

All angles inside the triangle will equal 180

Set your formula up as

180 = x + 120 + 20

180 - 120 - 20 = x

40 = x

y+x will also equal 180, therefore

180 = y + x

180 = y + 40

180 - 40 = y

140 = y

C.) Add 5 to both sides.

Step-by-step explanation:

Add five to both sides.

x - 5 = 6

What is the area of a rectangle?

Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,

[tex]A=a\times b[/tex]

Here, (a)is the length of rectangle and (b) is the width of the rectangle

The area of the given rectangle is,

[tex]A=(x^4 +4x^3 +3x^2 - 4x - 4),[/tex]

The length of the given rectangle is,

[tex]L=x^3+ 5x^2 +8x+ 4).[/tex]

As, the area of a rectangle is the product of the length and the width of the rectangle. Let suppose the width of the rectangle is f(x). Therefore,

[tex](x^4 +4x^3 +3x^2 - 4x - 4)=(x^3+ 5x^2 +8x+ 4)\times f(x)[/tex]

Solve it further as,

[tex]f(x)=(x^4 +4x^3 +3x^2 - 4x - 4)-(x^3+ 5x^2 +8x+ 4) \\f(x)=(x^4 +4x^3 +3x^2 - 4x - 4-x^3+ 5x^2 +8x+ 4[/tex]

Separate the like terms with same power of variable as,

[tex]f(x)=x^4 +4x^3-x^3 +3x^2 + 5x^2- 4x +8x- 4 + 4\\f(x)=x^43x^3+8x^2+4x[/tex]

Hence, the width of the rectangle, for which area and length provided in polynomial equation form is,
