For what value of x does mz1 = 90° ? 100° x + 10)

Answer:

You can solve this with common sense, but I'll do it for you and read my explanation before you demand an answer.

Step-by-step explanation:

When you look at a right angle, one forms 90°

A square has 4 sides, each should measure 90°.

That is how we know that point C measures 90°.

Now let's solve for x.

100+(x+10)+90°=90°

Solve the equation:

100+x+10+90=90

Step 1 : Solve for both sides.

100+x+10+90=90

(x)+(100+10+90)=90 ADD LIKE TERMS!

x+200=90

Step 2: Subtract 200 from both sides so you can make them equal.

x+200−200=90−200

x=−110

So, we get that <em>x=-110</em>. So <em>the blank side</em> should measure <em>90 degrees</em>.

Ah! Okay, need help solving 14, and just checking for 16 and 4.
Allisa [31]
4. Correct. You also could have used the limit test for divergence for the same conclusion (the summand approaches infinity).

14. I'm guessing the instructions are the same as for 16. Rewrite as

f(x)=\dfrac4{2x+3}=\dfrac{\frac43}{1-\left(-\frac{2x}3\right)}

Now recall that for |x|, we have

\dfrac1{1-x}=\displaystyle\sum_{n\ge0}x^n

so that for this function, we get

f(x)=\dfrac43\displaystyle\sum_{n\ge0}\left(-\frac{2x}3\right)^n

Because this is a geometric sum, this converges when \left|-\dfrac{2x}3\right|, or |x|. This would be the interval of convergence.

Your hunch about checking the endpoints is correct. Checking is easy in this case, because at the endpoints (-3/2 and 3/2) the series obviously diverges.

16. This one is kind of tricky, and there's more than one way to do it. The standard method would be to take the antiderivative:

F(x)=\displaystyle\int f(x)\,\mathrm dx=\int\frac{\mathrm dx}{(1+x)^2}=-\frac1{1+x}+C

We also have

\displaystyle-\frac1{1+x}=-\frac1{1-(-x)}=-\sum_{n\ge0}(-x)^n\implies F(x)=C-1-\sum_{n\ge1}(-x)^n

and differentiating this gives

f(x)=-\displaystyle\sum_{n\ge1}n(-x)^{n-1}=-\sum_{n\ge0}(n+1)(-x)^n=\sum_{n\ge0}(n+1)(-1)^{n+1}x^n

By the ratio test, this converges when

\displaystyle\lim_{n\to\infty}\left|\frac{(n+2)(-1)^{n+2}x^{n+1}}{(n+1)(-1)^{n+1}x^n}\right|

The limit reduces to

\displaystyle|x|\lim_{n\to\infty}\frac{n+2}{n+1}=|x|

and so the series converges absolutely for |x|. Checking the endpoints is also easy in this case. The factor of n+1 is a clear sign that the series will diverge at either extreme.
