Step-by-step explanation:

Area of the square = 6^2 = 36 cm^2

radius = 6 : 2 = 3 cm

Area of the four semicircles = 3^2 * π * 2 = 18 π cm^2

Total area in terms of π= 36 + 18π = 18(2+π) cm^2

Total area = 18(5.141593) = 92.548668 = 92.5 cm^2

A set is a collection of well-defined objects.

A subset contains all the elements or a few elements of the given set.

The improper subset is when it contains all the elements of the given set and the proper subset is when it doesn't contain all the elements of the given set.

Let N(U) be the no. who likes at least one of the rides which is

N(U) = (60 - 8) = 52 as 8 people do not like either kind of ride.

Given, The number of people who like roller coasters is 42 and the number who do not like water rides is 23.

∴ The no. of people who only likes roller coasters is (42 - 23) = 19.

Given,

Chloe is in the business of manufacturing phones.

She pay a daily cost $300 to rent for the building and equipment.

and, also pays a cost of $75 per phone produced for materials and labor.

Now, According to the question;

How to make a table of values and the equation for C, in terms of p, representing the total cost, in dollars?

The given parameters are:

Cost per phone = $75

Fixed cost of labor and material = $300

The total cost is represented as;

C(p) = Fixed cost + Cost per phone x Number of phones

So, we have

C(p) = 300 + 75 * p

Evaluate

C(p) = 300 + 75p

Hence, Using the above equation, the table of values is

p        C(p)

0        300

Answer:

Step-by-step explanation:

The option that describes the similarity relationship between the triangles is the option; The triangles are not similar, no expression for x can be found.

Similar triangles are triangles that  have all three interior angles of one triangle, congruent to the three angles of the other triangle.

The parameters of the triangles can be presented as follows;

ΔABC

∠A = 47°

∠C = 62°

AC = y

AB = w

BC = x

The measure of angle  ∠B = 180° - 47° - 52° = 81°

ΔDEF

∠D = 71°

∠E = 47°

DE = z

EF = u

DF = r

Therefore;

∠F = 180°- 71° -  47° = 62°

The angles of triangle ΔABC are not congruent to the angles of triangle ΔDEF, therefore; triangle ΔABC  and triangle ΔDEF are not similar.

Therefore;

The triangles are not similar, no expressions for x can be found.

The area of the square increasing when the area of the square is 16 cm² by the rate of 48cm²/s.

The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a shape or planar lamina.

Here,

A = s²

(dA)/(dt)

(dA/ds)*(ds/dt)

(ds)/(dt) = 6 cm/s

When A = 16 cm²

16 = s²

s = √(16)

s = 4 cm

(dA)/(dt) = 2 × 4 × 6 = 48 cm²/s

When the square is 16 cm², its area grows by 48cm²/s, or one-fourth of its initial size.

The linear equation will be y=34x+12 and the slop is 34 and y intercept is 12. And the sunflower will be 420 inches tall after a year.

Here, the sunflower was 12 inches when first planted and it grows 34 of an inch each month

So, the linear equation will be

y=34x+12

Where,

y=height

x=month

now,

the slope-intercept equation is

y=mx+c

Where,

m=slope

c=y intercept

Comparing this equation with equation (1)

We will get

m=34

c=12

so, the slope is 34 and y intercept is 12.

now,

The tree is 12 inches when it first planted and since then it grows 34 of an inch every month

So,

Height of tree after a year =12+34×12

Height of tree after a year = 12+408

Height of tree after a year = 420 inches.

Hence,

The tree will be 420 inches tall after a year.

Here we have the triangle.

Now, we have to find the angle ∠C.

While we looking into the given diagram,

We have the length of,

AB = 6

AC = 9

∠B = 105°

So, based on the law of sine it can be written as,

=> sin 105° / 9 = sin x°/6

Apply the value of sin 105° = 0.97, then we get,

=> 0.97/9 = sin x° / 6

Cross multiply them, then we get,

The statement that two of the team members must have personal records that are within four inches of each other it is not true for three high jumpers, and true for four high jumpers.

1 foot =  12 inches

So, for three high jumpers the statement is not true. A counterexample,

First player = 6 feet

Second player = 6 feet 6 inches

Third player = 6 feet 11 inches

Thus, personal record each player have interval more than 4 inches of each other.

For four high jumpers the statement is true. Since there are 4 jumpers and 3 intervals by the pigeonhole principle, at least two of the four jumpers have intervals within four inches. For example, in the image, the new jumpers should be placed in areas A, B, C and this makes at least two of the four jumpers have an interval of four inches.

Thus, the statement is not true for three jumpers and true for four jumpers.
