Definition: A set of points that form a line are called a ___ pattern.

Answer:

2.35 m²

Step-by-step explanation:

Divide the shape into shapes you can calculate the area of: a rectangle with a semi-circle on top, minus a square.

1. Calculate the area of the rectangle. Formula for area of a rectangle is length · width

1 m · 2 m = 2 m²

2. Calculate the area of the semi-circle. Formula for a semi-circle is [tex]\frac{\pi r^{2} }{2}[/tex] (use 3.14 for π) (radius is equal to half the diameter)

3.14(0.5)² = 0.785

0.785 ÷ 2 = 0.3925 m²

3. Combine the total area

2 + 0.3925 = 2.3925

4. Calculate the area of the square that will not be painted. Formula for area of a square is s² (side · side)

0.2² = 0.04 m²

5. Subtract the area of the square from the total area

2.3925 - 0.04 = 2.3525

2.3525 rounds to 2.35 m²

Answer:

  infinitely fast

Step-by-step explanation:

To have double the average speed, he must complete the two laps in the same amount of time that he spent completing the first lap. That is, he must complete the second lap in zero time.

Hamilton's average speed for the second lap should be infinite. (He needs to finish it in zero time.)

_____

  speed = distance/time

Multiplying by 2, we get ...

  2×speed = 2×distance/time . . . . . the time hasn't changed

Answer:

B. The variable s represents the number of students in each class.

C. The coefficient 14 represents the number of classes in the 9th grade.

Step-by-step explanation:

The total number can be found by multiplying the number of the things with the number of people producing it. For example if 5 boys make 5  colored ropes the total number of ropes will be 5*5= 25.

In this question the combinations rule is used for variuos number of classes which are 14. Now we have to find the number of students which are s (s-1). Suppose s= 6 so the number of students would be 6(6-1) = 6(5) = 30

We will multiply the number of classes 14 with the number of students s(s-1) to get the total number of cards produced.

Answer:

8x+8=7x

Step-by-step explanation:

The variable is supposed as x where ever the exact number is not mentioned.

n*8 + 8 = n*7 --> the answer must be n = -8 because:

8n + 8 = 7n

8n - 8n + 8 = 7n - 8n

8 = -1n

-8 = n

Step-by-step explanation:

The 7 and the 9.

Look closely

Answer:

<BAC = 20°

Step-by-step explanation:

It is given in the question that all 9 triangle which are formed are congruent, which means that in all triangles, the angle which is formed at point A is same.

Which means 9 angles collectively can be written as 9 · <BAC

If we consider all the 9 triangles, we can see in the figure that it forms a semicircle.

A semicircle has a total sum of angles equal to 180°

So we can write that:

9 · <BAC = 180°

Simplify for <BAC

<BAC = 20°

Answer:

1 zero:  Answer C

Step-by-step explanation:

Keep in mind that the polynomial value is zero at any root.  Therefore each point that is a root must lie precisely on the x-axis (where y = 0).  In the graph given there is only one such point  (Answer C)

Answer:

(a) Local Maximum (x,y) = (0,12)

    Local Minimum (x,y) = (-9,6) (smaller x-value)

    Local Minimum (x,y) = (6,3) (Larger x-value)

(b) Increasing = [tex](-9,0)\cup (6,\infty)[/tex]

    Decreasing = [tex](\infty,-9)\cup (0,6)[/tex]

Step-by-step explanation:

(a)

Local Maximum: The function gives maximum value in small neighborhood.

From the given graph it is clear that the maximum value of the function is 12 at x=0. So,

Local Maximum (x,y) = (0,12)

Local Minimum: The function gives minimum value in small neighborhood.

It is clear that the minimum value of the function is -6 and 3 at x=-9 and x=6. So,

Local Minimum (x,y) = (-9,6) (smaller x-value)

Local Minimum (x,y) = (6,3) (Larger x-value)

(b)

The function is increasing on -9<x<0 and after 6.

Increasing = [tex](-9,0)\cup (6,\infty)[/tex]

The function is decreasing on 0<x<6 and before -9.

Decreasing = [tex](\infty,-9)\cup (0,6)[/tex]

Answer:

m=2

Step-by-step explanation:

When you put a number into the inverse of a function (f^-1) you get the original number back.

Ex: f^-1(11) = (11-3)/2 = 4

f(4) = 2×4+3 = 11

So, f(-5)=-2

So, when x is -5,

f(x) = -2

f(x)=m(-5)+8

-2=m(-5) + 8

m=2

We decreased by 37%

Step-by-step explanation:

Let x be the starting temperature

We decrease by 10 percent which means we are left with 100-10 =90 percent

.90 x

Then we decrease by 30 percent, 100 - 30 = 70

( .90x) * .70

.63x

We  have .63 of the original left or 63%

100 -63 = 37

Answer:

Option A: P ≈ 38.7 in, A ≈ 63.7 in²

Step-by-step explanation:

We are told that △MNO ~△DEF. This means that they are similar triangles.

We can solve for this using scale factor.

a) Perimeter of △MNO

The scale factor of two similar triangles is equal to the ratio of the perimeter of the triangles

Scale factor(k) = ratio of the sides of the triangles

In the diagram we are given

Side of △MNO = 6.7in

Side of △DEF = 9in

Perimeter of △MNO = X

Perimeter of △DEF = 52in

Scale factor (k) = 6.7/9

Hence,

6.7/ 9 = X/52

Cross Multiply

9X = 6.7 × 52

X = 6.7 × 52/9

X = 38.711111111 inches

To the nearest tenth, Perimeter of △MNO = 38.7 inches

b) Area of △MNO

The square of the scale factor of two similar triangles is equal to the ratio of area of the triangles

Scale factor(k) = ratio of the sides of the triangles

In the diagram we are given

Side of △MNO = 6.7in

Side of △DEF = 9in

Area of △MNO = Y

Area of △DEF = 115in²

Scale factor (k) = 6.7/9

Hence,

(6.7/ 9)² = Y/115

6.7²/9² = Y / 115

Cross Multiply

9² × Y = 6.7² × 115

Y = 6.7²× 115 /9²

Y = 63.732716049 square inches

To the nearest tenth, Area of △MNO = 63.7 in²

Answer:

The last one

Step-by-step explanation:

The zeros of a function f(x) are the values of x such that f(x)=0. Since the coordinate y equals f(x), we must look for the values where y=0 (x-intersect).

Since f(x) is factorized, f(x)=0 only when one of its factors equals zero.

So we have

f(x) = 0 ===> x+2 = 0 OR x+1 = 0 OR x+4 = 0

and we have

x = -2 or x = -1 or x = -4

Hence the function must intersect the x-axis at these points.

The only graph that matches the requirements is the last one.

Answer:

B) 122 degrees.

Step-by-step explanation:

Consider the kite :- the 2 angles at the tangents are 90 degrees so we have:

9x - 5 + 14x + 24 + 90 + 90 = 360

9x - 5 + 14x + 24  = 180

23x + 19 = 180

23x = 161

x = 7

So the obtuse angle = 14(7) + 24

= 98 + 24

= 122 degrees.

Answer:

i

Step-by-step explanation:

The pattern is as follows

i^1 = i

i^2 = -1

i^3 = -i

i^4 = 1

Following this pattern, i^45 = i.

The value of the expression [tex]i^{45[/tex] is equal to i

Complex numbers are the square root of negative numbers. For instance:

[tex]\sqrt{-1} = i\\i^2 = -1[/tex]

Given the complex number:

[tex]i^{45}\\= (i^2)^{22} \times i\\= (-1)^{22} \times i[/tex]

Since any value raise to the even values will give a positive value hence;

[tex]=(-1)^{22} \times i\\=1 \times i\\= i[/tex]

This shows that the value of the expression [tex]i^{45[/tex] is equal to i

Answer:

The number of non-congruent triangles that can be formed by connecting 3 of the vertices of the cube is 3 non-congruent triangles

Step-by-step explanation:

From the three dimensional shape of a cube, triangles can be constructed from;

1) 6 side faces

2) 4 front face to opposite vertices triangles

3) 4 rear face to opposite vertices triangles

Each face can produce ₄C₃ = 4 triangles

Therefore;

The total number of triangles that can be formed = 4 × 6 + 4 × 4 + 4  × 4 = 56 triangles

Of the 56 triangles, it will be found that all 24 triangles from the different 6 direct faces will have the same dimension of 1, 1, √2 are congruent

The 24 triangles formed by the sides of the faces and an adjacent diagonal have the same dimension of 1, √2, √3 and are congruent

The 8 triangles formed by joining the three diagonals have the same dimension of √2, √2, √2 are congruent

Therefore, the 56 triangles comprises of a combination of three non-congruent triangle.

There are only 3 observed non congruent triangles formed by connecting three of the vertices of the cube.
