Whay is the value of g (-3l when g(x)= 2x-2

butalik [34]

Answer & Step-by-step explanation:

When you see g(x), then the number found in the place of x represents the value of x for that equation. So, the value of x for this equation is -3.

g(-3) = 2(-3) - 2

g(-3) = -6 - 2

g(-3) = -8

So, the value of g(-3) is -8

Find the length of AC Use that length to find the length of

Gekata [30.6K]

Answer:

1. AC = 5 cm

2. CD = 10.7 cm

Step-by-step explanation:

Looking at the left triangle, we see that AC is the side "opposite" of the angle given and AB is the "hypotenuse".

Which trigonometric ratio relates "opposite" to "hypotenuse"?

Yes, that's SINE.

So we can write:

$Sin(30)=\frac{AC}{10}\\AC=10*Sin(30)$

We know from 30-60-90 triangle, Sin(30) = 0.5, so we have:

$AC=10*Sin(30)\\AC=10*0.5\\AC=5$

Thus,

AC = 5 cm

Now, looking at right side triangle, we know AC, side "opposite" and we want to find CD, side "adjacent". Which trig ratio relates these 2 sides?

Yes, that's tan!

Thus we can write:

$Tan(25)=\frac{5}{CD}\\CD=\frac{5}{Tan(25)}$

Now using calculator, we get our answer to be:

CD = $\frac{5}{Tan(25)}=10.7$

CD = 10.7 cm
