Which expression is equivalent to the given expression? Assume the denominator does not equal zero.

MatroZZZ [7]

Answer:

Step-by-step explanation:

$\dfrac{a^{m}}{a^{n}}=a^{m-n} \ if \ m > n\\\\\\
\dfrac{a^{m}}{a^{n}}=\dfrac{1}{a^{n-m}} \ if \ n > m\\$

$\dfrac{16r^{6}z^{3}}{8r^{2}z^{6}}=\dfrac{2r^{6-2}}{z^{6-3}}\\\\
=\dfrac{2r^{4}}{z^{3}}$

How do you know if a square root of something is rational or irrational? like i know it can be represented by a fraction or a ra

ra1l [238]

The square root of a whole number will be rational if the whole number is a perfect square (i.e 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144 etc) and irrational otherwise.

Rational number is a number that can be described as m/n

so a fraction can be a rational number, 0.8=4/5
Irrational numbers can't be written as a fraction

The part about the number having to be a perfect square is still correct, if it's not a prefect square than it will just keep going(a decimal that never ends)

for example the square root of 0.64 is 0.8
and the square root of 10 is 3.162277...
as you can see the 0.64 one ends and is rational, whereas the 10 one just keeps going and is irrational.

The linear equation B. y = -x +7.5 best describes the given model. The mood rating for a student that spent 5.5 hours online would be 2.

Step-by-step explanation:

Step 1; We plot the points that fall on the line and that lie on an exact x or y coordinate. The following 4 points are plotted (0.5, 7), (2, 5.5), (2.5, 5) and (3.5, 4). We substitute the values of x in the given equations to see which best describes the model.

Step 2; When y = x + 7.5, we get the coordinates as (0.5, 8), (2, 9.5), (2.5, 10) and (3.5, 11).

When y = -x + 7.5, the coordinates are (0.5, 7), (2, 5.5), (2.5, 5) and (3.5, 4).

When y = $\frac{-1x}{2}$ + 7.5, the coordinates are (0.5, 7.25), (2, 6.5), (2.5, 6.25) and (3.5, 5.75).

So equation 2 has the closest values to the actaul graph.

Step 3; By substituting x = 5.5, y = -(5.5) + 7.5 = 7.5 - 5.5 = 2.

Find the value of x in the given<br> right triangle.

VMariaS [17]

Answer:

x = 10.6 units

Step-by-step explanation:

We can use sine to solve this since sine is opposite over hypotnuse.

sin(62) = x/12

.883 = x/12

x = .883 * 12

x = 10.6
