Slope is 2 .  

here is how you do the trick :  by reading on the graph

if you go forward of  1 on the X axis , how much did the line goes up or down ?  

Here at  0  on  X- axis, we are at 0 on the Y- axis.

If you go forward of  1 on X axis, you are at 2 on Y axis.  

So the slope is  + 2

Other technique by calculus  between two points.  

Take two diffents  point on the X axis.   Call them A and B  

Slope is  :   (  f(A) -f(B) )     /  A-B

exemple here :   we have two easy points . Take 0  as  A  and  1 as  B

We read on the graph :  

A = 0  and B = 1

f(A)= 0  and f(B) = 2

Now we apply  formula :    

(  f(A) -f(B) )     /  (A-B )

(0 -2 )  / (0-1)  =  -2/-1 =  2

Slope is 2

Easy, dont you think ?

Answer:

The value of x after simplification is 6, which when substituted in the given expression will make both the sides equal.

Step-by-step explanation:

It is given that the expression given below is to be simplified using the order of operations;

The given expression is;

=> (3×2)² + 8 = ___² + 8

Now, let us assume that the blank space is 'x' in the above-mentioned question;

Firstly,

We will solve the terms within brackets as per BODMAS rules that is multiplication of both the terms;

=> (3×2)² + 8 = x² + 8

=> 6²  + 8 = x² + 8

Now, we will solve the squares of the terms given above;

=> 36  + 8 = x² + 8

Now, we will add the terms as per BODMAS rules;

=> 44 = x² + 8

=> 44 - 8 = x²

Now, we will subtract the terms as per BODMAS rules;

=> 36 = x²

Now, we will square-root both the sides given above;

=> x = √36

=> x = 6

Therefore, the value of x after simplification is 6, which when substituted in the given expression will make both the sides equal.

Answer:

Step-by-step explanation:

1-    8

3 -    8+2= 10      

The range of the data set 1 and data set 2 is 4

Data set 1

The maximum value of the data set 1 = 7

The minimum value of the data set 1 = 3

The range is the difference between the maximum value and minimum of the data set

Range = Maximum value - Minimum value

Range of the data set 1 = 7 - 3

= 4

Data set 2

The maximum value of the data set 2 = 7
The minimum value of the data set 2 = 3

The range = Maximum value - Minimum value

The range of the data set 2 = 7 - 3

= 4

Hence, the range of the data set 1 and data set 2 is 4

Answer:

d

Step-by-step explanation:

Answer:

The series third has a sum of 5 option (C) is correct because the sequence represents the sum of the infinite terms.

What is a sequence?

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

We have a series shown in the picture.

The geometric sequence is shown in the options.

As we know, in the geometric sequence there is a first term and common difference

In the first sequence:

First term a = 2

Common difference = 2(0.1)/2

Common difference d = 0.1

The sum of the infinite series is:

S = a/(1 - r)

S = 2/(1 - 0.1)

S = 2.22

In the second sequence:

First term a = 15

Common difference = 15(0.3)/15

Common difference d = 0.3

The sum of the infinite series is:

S = a/(1 - r)

S = 15/(1 - 0.3)

S = 21.42

In the third sequence:

First term a = 4

Common difference = 4(0.2)/4

Common difference d = 0.2

The sum of the infinite series is:

S = a/(1 - r)

S = 4/(1 - 0.2)

S = 5

Thus, the series third has a sum of 5 option (C) is correct because the sequence represents the sum of the infinite terms.

Unitary method is a concept in which the value of a single unit is first found out and then multiplied by the necessary value to get the required answer.

Here, we are given that a grading machine can grade 96 multiple choice tests in 2 minutes.

This means that the machine will take 2/96 minutes to grade one multiple choice test

X = number of minutes taken by the machine to grade 300 multiple choice tests

Thus, we can use the proportion 2/96 to predict X in the following manner-

X = 2/96 (300)

The Surface area of a cone is 308.647 sq. inches.

What is the Surface area of cone ?

The area occupied by the surface / boundary of a cone. It is always measured in square units. Stacking many triangles and rotating them around an axis gives the shape of a cone. As it has a flat base, thus it has a total surface area as well as curved surface area.

The surface area of the cone can be given by finding the area of the sector by using the formula,

Area of the sector (in terms of length of arc) = (arc length x radius) / 2 = ((2πr) x l) /2 = πrl.

We are given the height and radius

h = 19 inches

r = 5 inches

The formula for Surface Area is:

Surface Area = πrl

We have to find slant height first:

[tex]l=\sqrt{h^{2}+r^{2} }[/tex]

[tex]l=\sqrt{19^{2}+5^{2} }\\ l=\sqrt{361+25}\\l= \sqrt{386}[/tex]

[tex]l=19.467 inches[/tex]

SA = πrl (π = 3.14)

Applying the triangle midsegment theorem, the length of BC is: 12 units.

The segment that connects the midpoints of two sides of a triangle is referred to as the midsegment of a triangle.

According to the triangle midsegment theorem, this midsegment is parallel to the third side of the triangle and also has a length that is half of the length of the third side of the triangle.

That is: length of midsegment = 1/2(length of the third side).

Given the following:

DE is a midsegment and is parallel to BC, a third side.

DE = 6 units

Thus, based on the triangle midsegment theorem, DE = 1/2(BC)

Substitute

6 = 1/2(BC)

2(6) = BC

12 = BC

BC = 12 units.

In conclusion, applying the triangle midsegment theorem, the length of BC is: 12 units.
