Answer:

2x² + 12x + 10

Step-by-step explanation:

Area of a rectangle = width x length

Therefore,

Area = (x + 1)(2x + 10)

Expand the brackets:    2x² + 10x + 2x + 10

Combine like terms:      2x² + 12x + 10

A quadratic expression is an expression with the variable with the highest power of 2

The pennies placed on the squares D, E, F, G, and H will be 8, 16, 32, 64, and 128 pennies.

Given

There are 8 rows and 8 columns, which means 64 squares on a chessboard.

We are placing 1 penny on Row 1 Column A, 2 pennies on Row 1 Column B, 4 pennies on Row 1 Column C, and so on.

A matrix (plural matrices) is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns, which is used to represent a mathematical object or a property of such an object.

So, we are increasing the number of pennies twice the amount of the previous square.

So, the pennies on next squares will be,

[tex]\rm Column \ D = 2\times 4=8\\\\Column \ E = 2\times 9=16\\\\Column \ F= 2\times 16=32\\\\Column \ G= 2\times 32=64\\\\Column \ H = 2\times 64=128[/tex]

Therefore, the pennies placed on the squares D, E, F, G, and H will be 8, 16, 32, 64, and 128 pennies.

Answer:

0.13

Step-by-step explanation:

to change a percent to a decimal you just move the decimal 2 places to the left

Answer:

13% = 0.13 in decimal form.

Step-by-step explanation:

Percent means 'per 100'. So, 13% means 13 per 100 or simply 13/100.

If you divide 13 by 100, you'll get 0.13 (a decimal number). Read more below on this webpage.

As you can see, to convert from percent to decimal just divide the percent value (13) by 100, and remove the "%" sign.

Answer:

it's D because

So you then divide 15/3=5

Answer:

1. Dots

2.Blank

3. Stripes

4. Stars

Step-by-step explanation:

Well the total is 30 and we just have to see the fraction of each time in landed on a specific part of the spinner. So first the probability of landing on dots is 6/30 = 1/5

Then the experimental probability of getting a blank is 8/30 = 4/15

Continuing in the same manner getting stripes would have a chance of  12/30 which is 2/5

Finally I'm gonna let you think about how I got the last one and why I did what I did :)

Since PS = RS, the triangle PRS is isosceles. This means the angles SPR and SRP are congruent.

The interior angles of any triangle sum to 180° in measure. So we have

∠SPR + ∠SRP + 90° = 180°

2 ∠SPR + 90° = 180°

2 ∠SPR = 90°

∠SPR = a = 45°

The sequence of number of color and black and white photos would look like this: 5 color/2 black and white, 15 color/6 black and white, 20 color/8 black and white, and 30 color/12 black and white.

To calculate the number of photos that follow in the sequence, it is necessary to take into account that for every 5 in color there are 2 in black and white.

We can also rely on the graph since it shows the constant relationship between both values. In it we can identify the equivalence between both types of photos.

Step-by-step explanation:

Given

3(2x+1)=9

Distribute left side

3(2x+1)=9

3(2x)+3(1)=9

6x+3=9

Subtract 3 on both sides

6x+3=9

6x+3-3=9-3

6x=6

Divide both sides by 6 to isolate "x"

6x=6

6x/6=6/6

x=1

Final answer

x=1

Answer:

x=1

The perimeter of the area of the pen the farmer intends to build for his

ship includes the length of the permanent stone wall.

Response:

i) The length and width of the rectangular pen are; x, and [tex]\dfrac{100 - x}{2}[/tex], therefore;

[tex]ii) \hspace{0.5 cm}\dfrac{dA}{dx} = 50 - x[/tex]

[tex]\dfrac{d^2A}{dx^2} = -1[/tex]

iii) The value of x that makes the area as large as possible is x = 50

Given:

The length of fencing the farmer has = 100 m

Part of the area of the pen is a permanent stone wall.

Let x represent the length of the stone wall, we have;

2 × Width = 100 m - x

Therefore;

Width, w, of the rectangular pen, [tex]w = \mathbf{\dfrac{100 - x}{2}}[/tex]

Area of a rectangle = Length × Width

Area of the rectangular pen, is therefore;

[tex]ii) \hspace{0.5 cm} \mathbf{\dfrac{dA}{dx}}[/tex], and [tex]\mathbf{\dfrac{d^2A}{dx^2} }[/tex] are found as follows;

[tex]\dfrac{dA}{dx} = \mathbf{\dfrac{d}{dx} \left( \dfrac{1}{2} \cdot x \cdot (100 - x) \right)} = \underline{50 - x}[/tex]

[tex]\dfrac{d^2A}{dx^2} = \mathbf{ \dfrac{d}{dx} \left( 50 - x\right)} = \underline{-1}[/tex]

iii) The value of x that makes the area as large as possible is given as follows;

Given that the second derivative, [tex]\dfrac{d^2A}{dx^2} =-1[/tex], is negative, we have;

At the maximum area, [tex]\dfrac{dA}{dx} = \mathbf{0}[/tex], which gives;

[tex]\dfrac{dA}{dx} = 50 - x = 0[/tex]

x = 50

Answer:

The function is not continuous on the interval, so the extreme value theorem does not apply

Step-by-step explanation:

Recall that the Extreme Value Theorem states that if a function is continuous on a closed interval [a,b], then the function must have a maximum and a minimum on the interval. Given that the function is discontinuous at x=0 which gives off a vertical asymptote, this does not meet the requirements of the theorem.
