Rápido y fácil, trigonometría. Urgente porfavor
enot [183]

Answer:

The angle \theta measures approximately 28.81^o

Step-by-step explanation:

Since this problem involves the finding of an angle in a right angle triangle for which we know the opposite side and the adjacent side, the trigonometric function that relates them is the tangent:

tan(\theta)=\frac{opposite}{adjacent}

Then, for our case we get a starting equation that reads:

tan(\theta)=\frac{opposite}{adjacent} \\tan(\theta)=\frac{7.7}{14}

and for which we need to solve for \theta. Then we use the arctangent function to get the final answer:

tan(\theta)=\frac{7.7}{14} \\\theta=arctan(\frac{7.7}{14})\\\theta= 28.81^o

Which expression below gives the average rate of change of the function g(x) = -x2 - 4x on the interval 6 ≤ x ≤ 8 ?
Scrat [10]

Answer:

the first selection (see below)

Step-by-step explanation:

The average rate of change (m) on the interval [x1, x2] is given by ...

... m = (g(x2) -g(x1))/(x2 -x1)

For g(x) = -x²-4x and (x1, x2) = (6, 8), the expression is the one attached.

Which set of ordered pairs represents a function?
mel-nik [20]
The one that doesn't have an "x" repeated, that is an X-REPEAT
notice, the pair is just an x,y  pair.. .so if the "x" is repeated, is NOT a function

let's see

\bf \{(2, -2), (\boxed{1}, 5), (-2, 2), (\boxed{1}, -3), (8, -1)\}\impliedby \textit{has an "x" rep}eated\\\\&#10;\{(3, -1), (7, 1), (-6, -1), (9, 1), (2, -1)\}\\\\&#10;\{(6, 8), (5, 2), (\boxed{-2}, -5), (1, -3), (\boxed{-2}, 9)\}\impliedby \textit{has an "x" rep}eated\\\\&#10;\{(\boxed{-3}, 1), (6, 3), (\boxed{-3}, 2), (\boxed{-3}, -3), (1, -1)\}\impliedby \textit{an "x" rep}eated
