The question isn't correctly given, a possible format is in the comment below, however, the explanation will cover then concept which can be applied to different but similar

Answer:

10048576 ways

Step-by-step explanation:

We are given a question, from which we can choose aby of 4 options, this gives ua 4 possible choices for 1.

This will also apply if we have more than 1 question with the same number of options.

This can be called the product rule, as each possibility is the same of each question given :

Therefore, given 10 questions:

. We have

4 * 4 * 4 * 4 * 4 * 4 * 4 * 4 * 4 * 4 = 4^10 = 10048576 ways

if a second function is defined by the formula g(x)=2x-7/3, then what is the value of g(f(1))? show the work that leads to your

nydimaria [60]

YOU NEED THE VALUE OF f(1), OR THERE IS MORE MERIT TO THE QUESTION, BUT HERE IS HOW IT WOULD BE BASED ON THE MERITS GIVEN

$g(x) = 2x - \frac{7}{3} \\ g(f(1)) = 2(f(1)) - \frac{7}{3} \\ g(f(1)) = (2 \times f(1)) - ( \frac{7}{3} )$

Standing at a trailhead, you look up at a 54 degree angle and see your friend's cell phone reflecting the sun. You know that she

So check the picture below

recall your SOH CAH TOA $\bf sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad \qquad 
% cosine
cos(\theta)=\cfrac{adjacent}{hypotenuse}

\\ \quad \\\\
% tangent
tan(\theta)=\cfrac{opposite}{adjacent}$

which identity uses only
angle
opposite
adjacent?

well, is Ms Tangent.. thus $\bf tan(\theta)=\cfrac{opposite}{adjacent}\implies tan(54^o)=\cfrac{1200}{x}$

solve for "x", make sure your calculator is in Degree mode, since the angle is in degrees
