The function f(x) = -3cos(3x+ x/4 ) has amplitude of what

Mathematics
1 answer:
Pepsi [2]3 years ago
5 0

Answer:

amplitude = 3

Step-by-step explanation:

The standard form of a cosine function is

f(x) = a cos(bx + c) + d

amplitude = | a |, period = \frac{2\pi }{b}

phase shift = - \frac{c}{b}, d is the vertical shift

Given the above function, then

amplitude = | - 3 | = 3

Please help I'll give 100 points to whoever is correct
levacccp [35]

Answer:

110.5 yd²

Step-by-step explanation:

Separate the figure into 1 triangle and 3 rectangles.

(see attached image)

<u>Area 1</u>

Area of a triangle = 1/2 × base × height

                             = 1/2 × (7 + 2 + 2) × 7

                             = 1/2 × 11 × 7

                             = 38.5 yd²

<u>Area 2</u>

Area of a rectangle = width × length

                                 = 3 × (5 + 2 + 2)

                                 = 3 × 9

                                 = 27  yd²

<u>Area 3</u>

Area of a rectangle = width × length

                                 = 5 × (5 + 2)

                                 = 5 × 7

                                 = 35  yd²

<u>Area 4</u>

Area of a rectangle = width × length

                                 = 2 × 5

                                 = 10  yd²

<u>Total Area</u>

Area 1 + Area 2 + Area 3 + Area 2 = 38.5 + 27 + 35 + 10

                                                        = 110.5 yd²
