Answer:

∠B = 36.87

Step-by-step explanation:

Since you are trying to find the angle measurement, you must use the inverse of cosine: $cos^{-1}$ (you're using cosine because you have the opposite side and adjacent side):

$cos^-1(4/5)$

≈36.87

What is the answer to this question?

sukhopar [10]

First plug in f and g:
$3 x^{2} +1- [1-x]$
Then distribute $3 x^{2} +1-1+x$
Combine like terms
$3 x^{2} +x$
Now plug in 2 for x
$3( 2^{2} )+2$
3(4)+2=12+2=14

Hope that helps

2. Provide the next three terms in the sequence and

vivado [14]

The next three terms of -243, 81, -27, 9 is $-3,1, \frac{-1}{3}$ The given series is geometric series

<u>Solution:</u>

Given, series is -243, 81, -27, 9, …

We have to find the next three terms of the above given series.

Now, the given series can also be written as

$-243,-243 \times\left(\frac{-1}{3}\right)^{1},-243 \times\left(\frac{-1}{3}\right)^{2},-243 \times\left(\frac{-1}{3}\right)^{3}$

We can say that, above series is in Geometric Progression with first term = -243 and common ratio = $\frac{-1}{3}$

Then, next three term would be,

$-243 \times\left(\frac{-1}{3}\right)^{4},-243 \times\left(\frac{-1}{3}\right)^{5},-243 \times\left(\frac{-1}{3}\right)^{6} \rightarrow-3,1, \frac{-1}{3}$

Hence, the next three terms of given G.P series are $-3,1, \frac{-1}{3}$
