the figure below shows andrews plan for a deck. Explain how to use triangles and rectangles to determine the area of the deck.
ELEN [110]

To find the area of the deck, we need to calculate the area of triangle and rectangles

Lets find the area of triangle A

Area of triangle = \frac{1}{2} * base * height

base = 9 and height =10

So area of triangle A = \frac{1}{2} * 9 * 10= 45

Area of rectangle = Base * height

Base of rectangle B = 9ft

Height of rectangle B = 12ft

Area of rectangle B = 9*12 = 108 square feet

Base of rectangle C = 24ft

Height of rectangle C = 22ft

Area of rectangle C = 24 * 22 =528 square feet

Area of the deck = Area of A + area of B + area of C

= 45 + 108 + 528

= 681 square feet

An object oscillates 4 feet from its minimum height to its maximum height. The object is back at the maximum height every 3 seco
bulgar [2K]

Answer:

y=2\text{cos}((\frac{2\pi}{3})t)

Step-by-step explanation:

We have been given that an object oscillates 4 feet from its minimum height to its maximum height. The object is back at the maximum height every 3 seconds. We are asked to find the cosine function that can be used to model the height of the object.

We know that standard form of cosine function is y = A\cdot \text{cos}(Bt-C)+D, where,

|A| = Amplitude,

Period = \frac{2\pi}{|B|},

C = Phase shift,

D = Vertical shift.

Since distance between maximum and minimum is 4, therefore, amplitude will be half of it, that is, A = 2.

Since objects gets back to its maximum value in every 3 seconds, therefore, period of the function is 3 seconds. We know that period is given by \frac{2\pi}{|B|}, therefore, we can write \frac{2\pi}{|B|}=3, therefore, B = \frac{2\pi}{3}.

We haven't been given any information about phase and mid-line, we can assume the values of C and D to be zero .

Therefore, our function required function would be y=2\text{cos}((\frac{2\pi}{3})t).

Answer:

{x}^{2}  - 2x + 3 =  - 6x \\  =  {x}^{2}  - 2x + 6x + 3 = 0 \\  \\  =  {x}^{2}  + 4x + 3 = 0 \\  = (x + 1)(x + 3) \\  = x =  - 1and \: x =  - 3
