Please solve the question below 88
RideAnS [48]

Answer:

7361.56 yards

Step-by-step explanation:

Height of the tower = 906 yards

Mauricio's height = 2 yards

Angle of elevation = 7^{o}

Let the distance between Mauricio and the base of the tower be represented by x.

The difference between the height of tower and Mauricio's height = 906 - 2

                                               = 904 yards

So that applying the appropriate trigonometric function, we have;

Tan θ = \frac{opposite}{adjacent}

Tan 7^{o}  = \frac{904}{x}

0.1228 = \frac{904}{x}

x = \frac{904}{0.1228}

  = 7361.5635

x = 7361.56 yards

The distance between Mauricio and the base of the tower is 7361.56 yards.

I need help on these three questions I’m so confused on how to answer them
GalinKa [24]

Answer:

  1.  S(1) = 1; S(n) = S(n-1) +n^2

  2. see attached

  3. neither

Step-by-step explanation:

1. The first step shows 1 square, so the first part of the recursive definition is ...

  S(1) = 1

Each successive step has n^2 squares added to the number in the previous step. So, that part of the recursive definition is ...

  S(n) = S(n-1) +n^2

__

2. See the attachment for a graph.

__

3. The recursive relation for an arithmetic function is of the form ...

  S(n) = S(n-1) +k . . . . . for k = some constant

The recursive relation for a geometric function is of the form ...

  S(n) = k·S(n-1) . . . . . . for k = some constant

The above recursive relation is not in either of these forms, so it is neither geometric nor arithmetic.

1 2 3 4 5 6 7 8 9 10 Susan plans to use 120 feet of fencing to enclose a rectangular area for a garden. Which equation best mode
Troyanec [42]

Answer:

Area = 60x - x^2

Step-by-step explanation:

Given

Perimeter = 120

Side\ 1 = x

Required

The area of the garden

First, we calculate the length of the other side using:

Perimeter = 2 *(Side\ 1 + Side\ 2)

This gives:

120 = 2 *(x + Side\ 2)

Divide both sides by 2

60 = x + Side\ 2

Make Side 2 the subject

Side\ 2 = 60 - x

So, the area of the garden is:

Area = Side\ 1 * Side\ 2

Area = x * (60 - x)

Expand

Area = 60x - x^2
