PLLSSS REALLY URGENT <br> If g(x)=3x+4, determine n that g(-3)=g^-1(n).

grigory [225]

Answer:

we have:

g(-3) = 3.(-3) + 4 = -5

$g {}^{ - 1} (n) = \frac{1}{3n + 4}$

because

$g( - 3) = g {}^{ - 1} (n)$

$- 5 = \frac{1}{3n + 4} \\ \\ < = > - 5(3n + 4) = 1 \\ \\ < = > - 15n - 20 = 1 \\ \\ < = > n = \frac{ - 21}{15} \\ \\ < = > n = \frac{ - 7}{5}$

Help!

GaryK [48]

Answer:

The computation of the angles show that the value of sin x and cos y will be 4/5 and 3/5 respectively.

How to calculate the angles?

From the information, we've to compute the length of the hypothenuse using Pythagoras theorem.

Therefore, 4² + 3² = hypothenuse²

hypothenuse² = 16 + 9

hypothenuse² = 25

hypothenuse = ✓25.

hypothenuse = 5

Therefore, sin x = opposite/hypothenuse = 4/5

cos y = adjacent/hypothenuse = 3/5

In conclusion, the values are 4/5 and 3/5.

4. What is the measure of each interior angle of a regular 28-gon?

melomori [17]

Step-by-step explanation:

Measure of each interior angle of 28 sided polygon

$\frac{(28 - 2) \times 180 \degree}{28} \\ \\ = \frac{26 \times 180 \degree }{28} \\ \\ = \frac{4680 \degree }{28} \\ \\ = 167.14\degree \\$

He did not perform enough trials. The more trials you perform, the closer it gets to the predicted outcome.
