Answer:

The bottom one on the right is a function.

Step-by-step explanation:

Its the bottom one on the right because it is the only one which passes the vertical line test for a function.

This test states that if we draw any vertical line through the graph and it only passes through the graph at one point only then the graph is a function.

What is the following simplified product? Assume x 0.<br> (sqrt6x^2+4sqrt8x^3)(sqrt9x-xsqrt5x^5)

e-lub [12.9K]

Answer:

Step-by-step explanation:

Keep in mind, whatever is inside of the square root, stays inside of the square root, and whatever is outside, stays outside, they don't multiply together. With parenthesis, exponents multiply, if there's no parenthesis, the exponents don't multiply. In this case, the exponents add.

Multiply each one together:

sqrt(6x^2) x sqrt(9x) = sqrt(54x^3)

sqrt(6x^2) x -(x sqrt(5x^5)) = -x sqrt(30x^7)

4 sqrt(8x^3) x sqrt(9x) = 4 sqrt(72x^4)

4 sqrt(8x^3) x -(x sqrt(5x^5)) = -4x sqrt(40x^8)

Then simplify:

sqrt(54x^2) = 3x sqrt(6x)

x sqrt(30x^7) = -x^4 sqrt(30x)

4 sqrt(72x^4) = 24x^2 sqrt(2)

-4x sqrt(40x^8) = -8x^5 sqrt(10)

In the figure below, BD and EC are diameters of circle P. What is the arc measure of AE in degrees?

Snowcat [4.5K]

Answer:

27°

Step-by-step explanation:

Since BD is a diameter then arc BD = 180°

∠ APE = 180° - (90 + 63)° = 180° - 153° = 27°

The measure of the arc AE is equal to the angle at the centre subtended by it.

arc AE = ∠ APE = 27°

What is the unit ratio for a button of 16 grams and 2 milliliters?

Reika [66]

Answer:

The unit ratio would be 8 grams per milliliters

Step-by-step explanation:

Since, the unit ratio is a fraction with denominator 1,

In other words, the amount of one quantity in unit amount of other quantity is called unit rate or unit ratio.

Here, the amount first quantity = 16 grams,

The amount of second quantity = 2 milliliters,

Thus, unit ratio = $\frac{\text{First quantity}}{\text{Second quantity }}$

$=\frac{16}{2}$ = 8 grams per milliliters
