Rápido y fácil, trigonometría. Urgente porfavor

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

LenaWriter [7]

Answer: $310,000

Step-by-step explanation:

In 40 additional years, the amount she made less than her college counterparts was;

= 10,000 * 40

= $400,000

She however made $90,000 more than them as they went to college;

= 400,000 - 90,000

= $310,000

The long-term financial cost was $310,000.

What is the maximum number of relative extrema a polynomial function can have?
creativ13 [48]
Relative extrema occur where the derivative is zero (at least for your polynomial function). So taking the derivative we get

<span>20<span>x3</span>−3<span>x2</span>+6=0

</span><span> This is a 3rd degree equation, now if we are working with complex numbers this equation is guaranteed to have 3 solutions by the fundamental theorem of algebra. But the number of real roots are 1 which can be found out by using Descartes' rule of signs. So the maximum number of relative extrema are 1.</span>
