Answer:

Answer C is the only one in function notation.

Step-by-step explanation:

To find something in function notation, we look for 2 different criteria.

On the left side, it must say f( ), with a variable in the parenthesis.
On the right side, the variable being used must match that from the left side.

Since C is the only one that satisfies both of those needs, we know it is the answer.

Write the polar equation as a set of parametric equations.<br><br> r=3sinθ<br> Show all work.

AVprozaik [17]

Answer:

$x=t$

$y=\pm\sqrt{3t-t^2}$

Step-by-step explanation:

The given polar equation is;

$r=3\sin \theta$

We multiply both sides by r

$r^2=3r\sin \theta$

The corresponding rectangular equation is

$y^2+x^2=3x$

$y^2=3x-x^2$

$y=\sqrt{3x-x^2}$

Let x=t,

Then;

$y=\pm \sqrt{3t-t^2}$

Natasha's sculpture was 5 3/16 inches tall. Mayas was 4 times as tall.How much shorter was Natasha's sculpture than Mayas

Serjik [45]

Answer:

Natasha's sculpture is 249/16 or 15.5625 or 15 9/16 inches shorter than Mayas sculpture

Step-by-step explanation:

The height of Natasha sculpture is 5 3/16 inches tall. Let us convert the height to an improper fraction.

5 3/16 = 83/16 inches tall. Therefore,

Natasha's sculpture is 83/16 inches tall.

According to the question Mayas own sculpture was 4 times as tall as Natasha's own sculpture. Mathematically, Mayas sculpture height can be expressed as follows

Mayas sculpture height = 4(83/16)

Mayas sculpture height = 4 × 83/16

Mayas sculpture height = 332/16

Mayas sculpture height = 20.75 inches or 83/4 inches

To know how much shorter was Natasha's sculpture we subtract Natasha sculpture height from Mayas sculpture height.

Therefore,

83/4 - 83/16 = (332 - 83) /16 = 249/16 or 15.5625 or 15 9/16

Natasha's sculpture is 249/16 or 15.5625 or 15 9/16 inches shorter than Mayas sculpture
