1 second = 2 megabytes

1\frac{1}{2}\ seconds=3\ megabytes

2 seconds = 4 megabytes

Step-by-step explanation:

Given,

Time taken to download 5 megabytes = 2\frac{1}{2}=\frac{5}{2} seconds

\frac{5}{2}\ seconds = 5\ megabytes

Multiplying both sides by \frac{2}{5} to find unit rate

\frac{2}{5}*\frac{5}{2}\ second = \frac{2}{5}*5\\1\ second = 2\ megabytes

1 second = 2 megabytes

1\frac{1}{2}\seconds = \frac{3}{2}\ seconds

\frac{3}{2}\ seconds = \frac{3}{2}*2

\frac{3}{2}\ seconds = 3\ megabytes

1\frac{1}{2}\ seconds=3\ megabytes

2 seconds = 2*2 megabytes

2 seconds = 4 megabytes

What are the ratios of sine, cosine, and tangent for angle Y? sin(Y) = StartFraction X Z Over X Y EndFraction; cos(Y) = StartFra
Sholpan [36]

Answer:

\sin Y= \frac{XZ}{XY}

\cos Y= \frac{YZ}{XY}

\tan Y= \frac{XZ}{YZ}

Step-by-step explanation:

Given

See attachment for triangle

Required

Find \sin, \cos and \tan of angle Y

For angle Y:

Opposite = XZ

Adjacent = YZ

Hypotenuse = XY

The \sin of an angle is calculated as:

\sin\theta = \frac{Opposite}{Hypotenuse}

So:

\sin Y= \frac{XZ}{XY}

The \cos of an angle is calculated as:

\cos\theta = \frac{Adjacent}{Hypotenuse}

So:

\cos Y= \frac{YZ}{XY}

The \tan of an angle is calculated as:

\tan\theta = \frac{Opposite}{Adjacent}

So:

\tan Y= \frac{XZ}{YZ}
