Answer: D. 7^11

Step-by-step explanation:

For exponents with the same base, we just add the exponents and keep the same base. 7 is the same base; therefore 5+6=11 which means the answer is 7^11

Use the expressions that represent the length and width of the game board to write an equation that models the area of the figur
Ne4ueva [31]
The picture is incomplete and the width is missing.

I am going to show you how to do it using any width.

The length shown is x + 4 and the width starts with - x.

Assume the width is - x + a.

Then the area of the rectangle with dimensions x + 4 and - x + a is calculated in this way:

1) given: (x + 4) (- x + a)

2) use distribuitive property: (x)(-x) + (x)(a) + (4)(-x) + (4)(a)

= - x^2 +ax -4x + 4a

3) Combine like terms: - x^2 + (a -4)x + 4a

If the polynomial missing were - x + 7, the answer would be:

- x^2 + (7 -4)x + 4(7) = - x^2 + 3x + 28

With this you are able to get the answer using the real values.

Answer:

  29.7°

Step-by-step explanation:

In a right triangle representing the geometry of the problem, the side opposite the angle is the height of your observation (400 ft). The side adjacent to the angle is the distance from shore (700 ft).

You know the tangent ratio is ...

  Tan = Opposite/Adjacent

so your angle of depression satisfies ...

  tan(angle of depression) = (400 ft)/(700 ft)

Using the inverse function, we find ...

  angle of depression = arctan(4/7) ≈ 29.745°

The angle of depression is about 29.7°.
