Answer:

  (-∞, -5/2) ∪ (1, ∞)

Step-by-step explanation:

"Increasing" means the graph goes up to the right. It is increasing from the left up to the local maximum--the peak at left.

It is increasing again from the local minimum on the right to the right side of the graph.

The two sections where the graph is increasing are ...

  (-∞, -5/2) ∪ (1, ∞)

Step-by-step explanation:

Given data :

89 , 74 , 100 , 86 , 74 , 67 , 86 , 72 , 60 , 93 , 83 , 86

Arranging the data in ascending order, we have,

60 , 67 , 72 , 74 , 74 ,83 , 86 , 86 , 86 , 89 , 93 , 100

Here, n ( total no.of observation ) = 12

Answer:

$271.00. Remember to put it in the right format

Step-by-step explanation:

So since its 35 dollars per day, we can first do 35*4 to get 140. So just for having the car, it costs 125 dollars.

Now to find the amount of money for the miles, we can do 730*0.20=146

Now we add those two amounts so we do 125+146=271.

So $271.00

Mean: $1.615

Median: $1.49

Mode: $1.49

Answer: First we will substitute the numbers in place of the variables in the equation, and then we will use order of operations to solve.

7x + 6y would be equal to:

7(2) + 6(10)

Now we will perform the multiplication:

7 * 2 = 14

6 * 10 = 60

The equation now looks like:

14 + 60

This is equal to 74. Your answer is therefore 74.

Hi there! Hopefully this helps!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First we need to evaluate the variables into the expression.

7x + 6y = 7(2) + 6(10).

6 x 10 = 60

7 x 2 = 14.

60 + 14 = 74

Answer:

Step-by-step explanation:

F1 = 1

F2 = 1 + 2

F3 = 1 + 2 + 3

--> The n(th) figure has the number of oranges = the sum of the first n natural numbers, which has the general form:

F(n) = 1 + 2 + 3 + ... + n = n(n+1) / 2

So, 8th figure has:

F(8) = 8.(8+1) / 2 = 8 . 9 / 2 = 36

Answer:

The solution of the system of equation in coordinate form is (2, 0)

Step-by-step explanation:

The given equation are;

2·x - y = 4....................(1)

5·x + 2·y = 10..............(2)

Multiplying equation (1) by 2 and subtract it from equation (2) gives;

5·x + 2·y - 2 × (2·x - y) = 10 - 2×4

5·x - 4·x + 2·y - 2·y = 2

x = 2

From equation (1), we have 2·x - y = 4, when x = 2, we get;

2×2 - y = 4

y = 2×2 -4 = 0

y = 0

Therefore;

The solution of the system of equation in coordinate form is (2, 0).

Answer:

n = -3

Step-by-step explanation:

Original Equation:

11 (n-1) + 35 = 3n

Distributive Property:

11n + 24 = 3n

Subtract 24 from both sides:

11n + 24 - 24 = 3n - 24

Simplify:

11n = 3n - 24

Subtract 3n from both sides:

11n - 3n = 3n - 24 - 3n

Simplify:

8n = -24

Divide both sides by 8:

[tex] \frac{8n}{8} = \frac{ - 24}{8} [/tex]

Simplify:

n = -3

Answer:

n=-3

Step-by-step explanation:

Answer: x=2

Step-by-step explanation:

Given

9(x+1)=25+x

Distributive property

9x+9=25+x

Subtract x on both sides

9x+9-x=25+x-x

8x+9=25

Subtract 9 on both sides

8x+9-9=25-9

8x=16

Divide 8 on both sides

8/8 x=16/8

x=2

Answer:

40ft

Step-by-step explanation:

√100=10

10*4=40ft

Answer:

The correct answer is 40 feet.

Step-by-step explanation:

We know that the area of the square is 100 square feet.  We also know that we can find the area of the square using the formula A = s^2, where s represents the side length of the square.

A = s^2

If we plug in the value for the area that we are given, we get:

100 = s^2

To find the side length, we take the square root of both sides.

10 = s

To find the perimeter of a square, we should add up four times the side length (since there are 4 equal sides to a square).

Thus, the perimeter of a square is given by:

P = 4s = 4(10) = 40 feet

Therefore, the correct answer is 40 feet.

Hope this helps!

Answer:

60°, 100° and 120°

Step-by-step explanation:

The angles x, y and z all lie on straight lines adjacent to other angles, thus

x = 180° - 120° = 60°

y = 180° - 80° = 100°

z = 180° - 60° = 120°

Answer:

Answer:

4 gallons of 15% ethanol

5 gallons of 78% ethanol

Step-by-step explanation:

Given that:

Two types of gases:

1st gas with 15% ethanol

2nd gas with 78% ethanol

The gases are to be mixed in such a way that the mixture of gases comes out to be with 50% ethanol with volume of 9 gallons.

Let amount of gas with 15% ethanol used = [tex]x[/tex] gallons

Now, we are given that total volume is 9 gallons, then

amount of gas with 78% ethanol used = 9 - [tex]x[/tex] gallons

As per the question statement:

[tex]x\times 15\% + (9-x)\times 78\%=9\times 50\%\\\Rightarrow x\times 15 + (9-x)\times 78=9\times 50\\\Rightarrow 9\times 78-9\times 50=63x\\\Rightarrow 9\times 28=63x\\\Rightarrow \bold{x = 4\ gallons}[/tex]

Therefore, the answers are:

4 gallons of 15% ethanol

9 - 4 = 5 gallons of 78% ethanol

The number of gallons required of both kind would be as follows:

4 gallons having 15% ethanol

5 gallons having 78% ethanol

Given that,

The 2 kinds of gases are:

One with 15% ethanol

Other with 78% ethanol

Given that,

The gases(ethanol and gasoline) are diluted in a such a manner that it involves a total of only 50% ethanol.

Number of gallons she wants to use = 9

This shows that only 50% of 9 gallons i.e. 4.5 gallons of ethanol can be used.

Assuming x being the gasoline's measure that is diluted with 15% ethanol.

Now,

The gasoline's measure that is diluted with 78% ethanol would be = 9 - x gallons

Therefore,

x × 15% + (9-x) × 78% = 4.5

On solving, we get

x = 4 gallons

Thus,

The measure of gallons having 15% ethanol = 4

The measure of gallons having 78% ethanol = (9 - x)

= (9 - 4)

= 5 gallons

Answer:−21x−8

Step-by-step explanation: All sides have the same measure in a square, therefore all sides are 3x-8. Area is equal to 3x-8 times 3x-8 which is −21x−8

If the side of the square is (3x - 8), the area of the square is 9x² -48x + 64

A square is a two-dimensional figure that has four sides and all four sides are equal.

The area of a square is given as side².

We have,

Square:

Side = (3x - 8)

The area of a square.

= Side²

= (3x - 8)²

Factorize using [(a + b)² = a² + 2ab + b²].

Now,

(3x - 8)²

= 9x² + 8² - 48x

= 9x² -48x + 64

Answer:

Here the mistake is that she drew a circle from the point A to intersect the line rather the drawing arcs from the point C

The next another circle was drawn from the point of the intersection of the first circle and the intersection of both circles was used to draw the perpendicular at the midpoint of the intersection of both circles.

Step-by-step explanation:

To construct a line perpendicular to another line through a point the following steps are required

1) From the point, with the compass, C draw  to intersect the line at points A and B

2) From A and B with the compass made wider, draw arcs above and below the line to intersect each other

3) With the straight edge Draw a line passing through the intersections of the arcs drawn from A and B and extend the line to pass through the point C

The line constructed above is the perpendicular to the line l passing through the point C.
