Answer:

Option D. 37¼ ft

Step-by-step explanation:

The perimeter of the figure above can be obtained by adding all the lengths of each sides together. This can be obtained as follow:

The lengths of each sides are given below:

Top = 6¼ ft

Left = 9⅛ ft

Bottom = 9½ ft

Right = 7¾ ft

Top horizontal = 9½ – 6¼

= 19/2 – 25/4

= 13/4 ft

Top height = 9⅛ – 7¾

= 73/8 – 31/4

= 11/8 ft

Perimeter = 6¼ + 9⅛ + 9½ + 7¾ + 13/4 + 11/8

= 25/4 + 73/8 + 19/2 + 31/4 + 13/4 + 11/8

= 149/4

= 37¼ ft

Thus, the perimeter of figure is 37¼ ft

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).

Find the volume of the sphere
romanna [79]
V = \frac{4}{3}\pir^{3} is the formula to find the volume of a sphere.

First cube the radius (12)

12^{3} = 1728

Now multiply 1728 by 4/3 by multiplying it by 4, and then dividing the result by 3.

1728 x 4 = 6912

\frac{6912}{3} = 2304
 
Now, we multiply this number by \pi to get our final answer.
You typically use 3.14 to approximate \pi.

2304 x 3.14 = 7234.56

Therefore, the volume of a sphere with a radius of 12 will be approximately 7234.56

Hope this helps!!
Let me know if there's anything you don't understand and I'll try to explain as best I can.

Aleonysh [2.5K]

Answer:

Hence The composition (fog)(x) of the given function is x^2+12x+29.

Step-by-step explanation:

Given:

f(x) = x^2+2x-6

g(x)=x+5

We need to find (f o g)(x).

Solution:

Now we can say that;

(f o g)(x) = f(g(x))

(fog)(x) = (x+5)^2+2(x+5)-6

Now Applying distributive property we get;

(fog)(x) = (x+5)^2+2\times x+2\times5-6\\\\(fog)(x) = (x+5)^2+2x+10-6\\\\(fog)(x) = (x+5)^2+2x+4

Now Solving the exponent function we get;

(fog)(x) = x^2+2\times x\times 5+5^2+2x+4\\\\(fog)(x) = x^2+10x+25+2x+4\\\\(fog)(x) = x^2+12x+29

Hence The composition (fog)(x) of the given function is x^2+12x+29.
