Write a cosine function that has a midline of 2, an amplitude of 4 and a period of 4/7

ella [17]

Answer:

$y= 4cos(\frac{7\pi }{2}x)+2$

Step-by-step explanation:

We know that the transformations of a cosine equation can be shown as:

y=±a(b(x-h))+k

Where 'a' is the amplitude

'b' is the horizontal change (Do 2π/b to find the period)

'h' is the horizontal shift

and 'k' is the vertical shift or midline.

------------------------------------------------------

If the amplitude is 4, we can assume a=4.

Since the period is 4/7, we can solve for the 'b' value by:

$2\pi /\frac{4}{7}= \frac{7\pi }{2}$

Next, since the midline is 2, we know that a vertical shift of 2 occurred. Thus, the 'k' value is 2.

Writing this equation gives us:

$y= 4cos(\frac{7\pi }{2}x)+2$

I’ll give brainliest

faust18 [17]

Step-by-step explanation:

Let

c = 11.5 cm

a = 8.9 cm

b = ?

Since this is a right triangle, we can use Pythagorean theorem to find the length of side b:

$c^2 = a^2 + b^2$

$\Rightarrow b^2 = c^2 - a^2$

Taking the square root of the equation above, we get

$b = \sqrt{c^2 - a^2} = \sqrt{(11.5\:\text{cm})^2 - (8.9\:\text{cm})^2}$

$\:\:\:\:=7.3\:\text{cm}$
