So cos means adjacent over hypotenuse which would be 15/17 and you can’t simplify it down farther so 15/17 is your final answer.

$\cos X = \frac{\text{adjacent}}{\text{hypotenuse}} = \boxed{\frac{15}{17}}$

What is the inverse of the function g(x)=-\dfrac{2}{3}x-5g(x)=− 3 2 x−5g, left parenthesis, x, right parenthesis, equals, minu

Semenov [28]

Answer:

$g^{-1}(x)=-\frac{3}{2}x-\frac{15}{2}$

Step-by-step explanation:

Given function,

$g(x) = -\frac{2}{3}x-5$

Step 1 : Replace g(x) by y:

$y = -\frac{2}{3}x-5$

Step 2 : Swap x and y:

$x = -\frac{2}{3}y-5$

Step 3 : Solve the equation for y ( isolate y in the left side ):

$x +\frac{2}{3}y=-5$

$\frac{2}{3}y=-5-x$

$y=\frac{3}{2}(-5-x)$

$y=-\frac{15}{2}-\frac{3}{2}x$

$y=-\frac{3}{2}x-\frac{15}{2}$

Step 4: Replace y by $g^{-1}(x)$ :

$g^{-1}(x)=-\frac{3}{2}x-\frac{15}{2}$

Hence, the inverse of the function g(x) is $g^{-1}(x)=-\frac{3}{2}x-\frac{15}{2}$ .

The aircraft A330 flies at an average speed of 400 miles per hchor. The expression, 400t gives the distance traveled by the airc

Olenka [21]

The expression:

$d(t)=400t$

gives the distance traveled by the aircraft in t hours, so, for t = 6:

$\begin{gathered} t=6 \\ d(6)=400(6) \\ d(6)=\frac{2400mi}{h} \end{gathered}$

Look at the given angle.

mylen [45]

Other ways are m<1, YFP and m<F.

The angle is an acute angle because it is less than a right angle (less than 90 degrees).
