Answer:

$-a^{18}$

Step-by-step explanation:

So we have $(-a^{3} ) ^{4} *-a^{6}$

First what we must do is do the rule of out exponent by in exponent. A.K.A in parenthesis and out parenthesis.

So $(-a^3) ^4$

3 * 4 = 12

$a^{12}$

Now do the additive property :

$-a^{12} * a^6$

12 + 6 = 18

$-a^{18}$

Answer:

skewed to the left

Step-by-step explanation:

when you look at the graph, you look for where the peaks are. if the peak is not centered, it is skewed. in this case, it leans towards the left. hope this helps :)

Which function has an inverse that is also a function? {(–4, 3), (–2, 7), (–1, 0), (4, –3), (11, –7)} {(–4, 6), (–2, 2), (–1, 6)

9966 [12]

Answer:

1. {(–4, 3), (–2, 7), (–1, 0), (4, –3), (11, –7)}

Step-by-step explanation:

Info to consider:
Inverse of a function: (x, y) → (y, x)
Definition of a function: Every input will have exactly one output.

Let's analyze the functions:

1. {(–4, 3), (–2, 7), (–1, 0), (4, –3), (11, –7)}

It has unique y- values, its inverse won't have repeat x-values, so the inverse is also a function

2. {(–4, 6), (–2, 2), (–1, 6), (4, 2), (11, 2)}

It has repeat y values of 6 and 2. Its inverse it is going to cause repeat input numbers with different output. This won't be a function

3. {(–4, 5), (–2, 9), (–1, 8), (4, 8), (11, 4)}

It has repeat y values of 8. Its inverse it is going to cause repeat input numbers with different output. This won't be a function

4. {(–4, 4), (–2, –1), (–1, 0), (4, 1), (11, 1)}

It has repeat y values of 1. Its inverse it is going to cause repeat input numbers with different output. This won't be a function

So the first set of data is the only correct one

How do i do this???????????????

Anna [14]

We can answer this question using sine rule, as I'm sure you're aware of since you have drawn out the opposite angles and sides.

In case you need reminding, the sine rule is as follows:

$\frac{sin(A)}{a} = \frac{sin(B)}{b} = \frac{sin(C)}{c}$

Using the information you have provided, we can set A to be x, a to be 33 (as it's the opposite), B to be 102, and b to be 73 (again, as it's the opposite).

If we plug these values in to the sine rule, we get:

$\frac{sin(X)}{33}= \frac{sin(102)}{73}$

Now all we have to do is rearrange to find X.

$arcsine(33(\frac{sin(102)}{73})) = 26.2$ to 1DP
