We have to calculate the area of the square.

⠀⠀⠀⠀⠀★ Area of square = (Side)² ★

[tex] \dashrightarrow \quad \rm { Area = [10 - 3x(-2)]^2 \; cm^2} \\ [/tex]

[tex] \dashrightarrow \quad \rm { Area = [10 + 6x]^2 \; cm^2} \\ [/tex]

[tex] \dashrightarrow \quad \rm { Area = (10)^2 + (6x)^2 + 2(10 \times 6x) \; cm^2} \\ [/tex]

[tex] \dashrightarrow \quad \rm { Area = 100 + 36x^2 + 2(60x) \; cm^2} \\ [/tex]

[tex] \dashrightarrow \quad \underline{\boxed{\bf { Area = 100 + 36x^2 + 120x \; cm^2}}} \\ [/tex]

[tex]\rule{200}2[/tex]

Answer:

36x^2 + 120x + 100 cm^2.

Step-by-step explanation:

[10 - 3x (-2)]

= 10 + 6x

The area = (10 + 6x)^2

= (10 + 6x)(10 + 6x)

= 10*10 + 10*6x + 10*6x + 6x*6x

= 100 + 60x + 60x + 36x^2

= 100 + 120x + 36x^2.

Answer:

  D.  72sin(α)cos(α)

Step-by-step explanation:

Given two sides and the angle between, the area of a triangle can be found from the formula ...

  Area = (1/2)ab·sin(C)

Here, that translates to ...

  Area = (1/2)(12)(y)sin(α)

Using the trig relation ...

  Cos = Adjacent/Hypotenuse

we can find y:

  cos(α) = y/12

  y = 12·cos(α)

__

Substituting this into the area calculation above, we have ...

  Area = (1/2)(12)(12·cos(α))sin(α)

  Area = 72sin(α)cos(α)

It's the slope of the secant line to f(x) through the points (-3, f (-3)) and (9, f (9)),

[tex]\dfrac{f(9) - f(-3)}{9 - (-3)} = \dfrac{-7 - 1}{12} = -\dfrac8{12} = \boxed{-\dfrac23}[/tex]

Using function concepts, we have that:

The actual percentage of smokers in 2010 was of 23%, while the estimated was of 13%, thus, the model underestimated the percentage by 10%.

-----------------------------

The function is:

[tex]p + \frac{x}{2} = 33[/tex]

In which

The percentage can be written as a function of the number of years, that is:

[tex]p(x) = 33 - \frac{x}{2}[/tex]

-----------------------------

2010 is 2010 - 1970 = 40 years after 1970, thus, the estimate of the percentage in 2010 is:

[tex]p(40) = 33 - \frac{40}{2} = 33 - 20 = 13[/tex]

The actual percentage of smokers in 2010 was of 23%, while the estimated was of 13%, thus, the model underestimated the percentage by 10%.

Answer:

I am almost positive that the answer is 64 miles in one hour.

Step-by-step explanation:

In an hour the truck driver will cover the distance of 64 miles.

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. The speed is a scalar quantity and does not require direction to represent it.

Given that a truck driver drove 48 miles in 45 minutes. The distance covered by the truck in an hour will be calculated as below:-

45 minutes ⇒ 48 miles

1 minute ⇒ 48 / 45

60 minute ⇒ ( 48 x 60 ) / 45

1 hour ⇒ 64 miles

Therefore, in an hour the truck driver will cover the distance of 64 miles.

The simplified expression for the area of the frame of the photo is 8x4 = 32 sq inches.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it is given that,

Length of the photo = 4 inches

Width of the photo = 8 inches

Since, frame around the photo is the same width all the way around.

Therefore, area of the frame of the photo = Length x width

⇒ area of the frame of the photo = 8x4 = 32 square inches

which is the required expression for the area of the frame of the photo.

Thus, the simplified expression for the area of the frame of the photo is 8x4 = 32 sq inches.

Parameterize S by

Take the normal vector to S to be

Based on the information given, Arpi drinks 48.38 ounces of water.

Since the glass that holds 10.75 fluid ounces and Arpi drinks 4.5 glasses of water in one day, then the amount of water that Arpi drinks will be calculated thus:

= 10.75 ounces × 4.5 glasses

= 48.375 ounces

= 48.38 ounce to the nearest hundredths

In conclusion, Arpi drinks 48.38 ounces of water.
