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

How many real solutions exist for this system of equations?
Rom4ik [11]

Answer:

One

Step-by-step explanation:

Set each equations equal to each other

{x}^{2}  + 4 = 4x

{x}^{2}  - 4x + 4

Find the discrimant.

{ - 4 {}^{2} - 4(1)(4) } = 0

This means there is one real solution. Since the discramnt equal 0.

PROVE :<br><br>sin^2(-300°).cos^2 (120)+ cos^2(-240 ).sin^2(390)=1/4​
leva [86]

Step-by-step explanation:

\sin {}^{2} ( - 300)  \cos {}^{2} (120)  +  \cos {}^{2} ( - 240)  \sin {}^{2} (390)  =  \frac{1}{4}

\sin {}^{2} (60)  \cos {}^{2} ( {}^{} 120)  +  \cos {}^{2} (120)  \sin {}^{2} (30)

\frac{3}{4}  \frac{1}{4}  +  \frac{1}{4}  \frac{1}{4}

\frac{3}{16}  +  \frac{1}{16}  =  \frac{4}{16}  =  \frac{1}{4}

Answer:

\frac{4x+2}{x^2 - 9x + 8} = \frac{4x}{(x-8)(x-1)} + \frac{2}{(x-8)(x-1)}

Step-by-step explanation:

Given

\frac{4x+2}{x^{2}-9+8 } = \frac{A}{()(x-1)} + \frac{B}{()(x-8)}

Required

Fill in the gaps

Going by the given parameters, we have that

\frac{4x+2}{x^{2}-9+8 } = \frac{A}{()(x-1)} + \frac{B}{()(x-8)}

x^2 - 9x + 8, when factorized is (x-1)(x-8)

Hence; the expression becomes

\frac{4x+2}{(x-1)(x-8)} = \frac{A}{(x-8)(x-1)} + \frac{B}{(x-1)(x-8)}

Combine Fractions

\frac{4x+2}{(x-1)(x-8)} = \frac{A + B}{(x-8)(x-1)}

Simplify the denominators

4x + 2 = A + B

By direct comparison

A = 4x

B = 2

Hence, the complete expression is

\frac{4x+2}{x^2 - 9x + 8} = \frac{4x}{(x-8)(x-1)} + \frac{2}{(x-8)(x-1)}
