(co<br> Write a cosine function that has an amplitude of 2, a midline of 5 and a period of 8.
tatyana61 [14]

Answer:

<em>y=2 cos (π/4x-π/4)</em>

Step-by-step explanation:

<em>Given</em>

<em>A cosine function has an amplitude of 2, a midline of 5 and a period of 8.</em>

<em>To find: </em>

<em>A cosine function.</em>

<em>Explanation:</em>

<em>Let the function be,</em>

<em></em>y=Acos(ws+p)

<em>Since amplitude is 2.</em>

<em>Then,</em>

<em></em>A=2

<em>Also, since the period is 8.</em>

<em>Then,</em>

<em></em>w=\frac{2\pi }{8}

w=\frac{\pi }{4}

<em>And, since midline is 5.</em>

<em>Hence, the cosine function is,</em>

<em>y=2 cos (</em>\frac{\pi }{4}<em>x-</em>\frac{\pi }{4}

<em></em>

So far, 37 miles of a new highway have been completed. This is one mile less than two thirds of the entire length. How long will
blagie [28]
37 = 2/3x - 1
37 + 1 = 2/3x
38 = 2/3x
38 / (2/3) = x
38 * 3/2 = x
114/2 = x
57 = x <=== when complete, the highway will be 57 miles

Solve using quadratic formula<br> 5x^2-4x+3=0
Semenov [28]

Answer:

Impossible

Step-by-step explanation:

In 5x^2-4x+3=0, standard form, substitute these values in the quadratic formula:

a = 5; b = -4; c = 3

The quadratic formula is x = \frac{ -b ± \sqrt{b^{2} - 4ac}}{2a}

(ignore the weird capital A)

Substitute a b and c:

x = \frac{-(-4) ± \sqrt{(-4)^{2} - 4(5)(3)}}{2(5)}

Simplify:

x = \frac{4) ± \sqrt{16 - 60}}{10}

Because \sqrt{16-60} is the square root of a negative number, the answer would be imaginary.

Therefore, there are not solutions to this equation.

A solution is the same as the roots or zeroes, where the graph would cross the x-axis when graphed.

The graph never meets the x-axis. It looks like this:
