Let y = -1/3x - 5
1/3x = -y - 5
multiply through by 3
x = -3(y + 5)
so
inverse of f(x) = -3(x + 5)

In circle O, m∠R = 30.8°. Find m∠NOQ.

nordsb [41]

Given:

In circle O, m∠R = 30.8°.

To find:

The m∠NOQ

Solution:

Central angle theorem: According to this theorem, the central angle is always twice of subtended angle on the same arc.

Angle NOQ and angle NRQ are on the same arc but ∠NOQ is the central angle and ∠NRQ is the subtended angle on the arc NQ.

Using central angle theorem, we get

$m\angle NOQ=2\times m\angle NRQ$

$m\angle NOQ=2\times m\angle R$

$m\angle NOQ=2\times 30.8^\circ$

$m\angle NOQ=61.6^\circ$

Therefore, $m\angle NOQ=61.6^\circ$ .

Write the numbers in order from greatest to least.<br> -4, 2 1⁄5, -2 3⁄4, 1⁄10

Leviafan [203]

Answer:

2 1/5, 1/10, - 2 3/4, -4

Step-by-step explanation:

If you're ever confused about whether a number is greater than another number, think about them on a number line. If the number is further to the left than another number, it is less (for example, 0 is further to the left than 2).

Simplify completely: 8x+4/x^3+23÷4x^2-10x-6/9-x^2

Helen [10]

Answer:

The simplified form is: $-x^2-2x+\frac{4}{x^3}+\frac{23}{4x^2}-\frac{2}{3}$

Step-by-step explanation:

To simplify the expression given we, need to open the brackets, and if there is power term. Then we need to group all the like terms and then arrange in the descending order of powers of the given expression.

Now the expression that is given to us is:

$8x+\frac{4}{x^3}+\frac{23}{4x^2}-10x-\frac{6}{9}-x^2$

Here we will simplify it by grouping the like terms, as follows:

$8x+\frac{4}{x^3}+\frac{23}{4x^2}-10x-\frac{6}{9}-x^2\\=-x^2+8x-10x+\frac{4}{x^3}+\frac{23}{4x^2}-\frac{6}{9}=-x^2-2x+\frac{4}{x^3}+\frac{23}{4x^2}-\frac{2}{3}$

So this is the required simplified form.
