The correct option is Amplitude: 5; midline: y = 1.

Explanation:
Amplitude is the greatest distance/position from the axis. Since the top of the curve, strikes the y-axis at y= 5. Thus, amplitude is 5.
Midline is the point where the centre line (symmetry line passes). Clearly, in this curve the symmetry line is y= 1. So, midline is 1

Answer:

A

Amplitude: 4; midline: y = 1

Step-by-step explanation:

Amplitude = (min-max/2)

= 8/2

= 4

midline is just the middle which = 1

a bookshelf holds 43 books on each shelf is the total number of books proportional to the number of shelves in the bookshelf
Mama L [17]
If every shelf has the same amount of books, then it can be seen as proportional because one shelf has 43 and 2 have 86, and it keeps going up in a consistent way. 
so 43/1 = 86/2 .
Happy studying ^-^

given that sin theta= 1/4, 0 is less than theta but less than pi/2, what is the exact value of cos theta
lapo4ka [179]

Answer:

\cos{\theta} = \frac{\sqrt{15}}{4}

Step-by-step explanation:

For any angle \theta, we have that:

(\sin{\theta})^{2} + (\cos{\theta})^{2} = 1

Quadrant:

0 \leq \theta \leq \frac{\pi}{2} means that \theta is in the first quadrant. This means that both the sine and the cosine have positive values.

Find the cosine:

(\sin{\theta})^{2} + (\cos{\theta})^{2} = 1

(\frac{1}{4})^{2} + (\cos{\theta})^{2} = 1

\frac{1}{16} + (\cos{\theta})^{2} = 1

(\cos{\theta})^{2} = 1 - \frac{1}{16}

(\cos{\theta})^{2} = \frac{16-1}{16}

(\cos{\theta})^{2} = \frac{15}{16}

\cos{\theta} = \pm \sqrt{\frac{15}{16}}

Since the angle is in the first quadrant, the cosine is positive.

\cos{\theta} = \frac{\sqrt{15}}{4}

For which value of x must the expression square root of 19x be further simplified? A. 15. B 21. C 28. D 41
algol [13]
<span>The expression of the square root of 19x must be simplified when x is equal to 28. This is because possible factors of 28 can be seen to be 4 and 7, and 4 is a perfect square. This means it can be pulled outside of the square root when evaluated. The other options include only prime factors that could not be pulled out. (3,5), (3,7), (1,41)
   28 simplifies as such:
 Sqrt(19*28) = Sqrt(19*4*7) = 2*Sqrt(19*7) = 2*Sqrt(133).</span>
