I) Find the first 4 terms in the expansion of

Katyanochek1 [597]

Answer:

(i) $64+192 x^2+240 x^4+160x^6$

(ii) 1072

Step-by-step explanation:

<u>Part (i)</u>

Using Binomial series formula:

$(2+x^2)^6=2^6+6C1 \cdot 2^{6-1}\cdot x^2+6C2 \cdot 2^{6-2}\cdot(x^2)^2+6C3 \cdot 2^{6-3}\cdot(x^2)^3$

$=64+6 \cdot 32\cdot x^2+15 \cdot 16\cdot x^4+20 \cdot 8 \cdot x^6$

$=64+192 x^2+240 x^4+160x^6$

<u>Part (ii)</u>

<u /> $(1-\frac{3}{x^2})^2=(1-\frac{3}{x^2})(1-\frac{3}{x^2})$

$=1-\dfrac{6}{x^2}+\dfrac{9}{x^4}$

$(2+x^2)^6(1-\frac{3}{x^2})^2=(64+192 x^2+240 x^4+160x^6)\left(1-\dfrac{6}{x^2}+\dfrac{9}{x^4} \right)$

$=64-\dfrac{384}{x^2}+\dfrac{576}{x^4}+192x^2-1152+\dfrac{1728}{x^2}+240x^4-1440x^2+2160+...$

There is no need to keep expanding since the remaining will include the variable.

Therefore, the term independent of x = 64 - 1152 + 2160 = 1072

Geometry Please Help (will mark brainliest)

SOVA2 [1]

The answer is 14 because you have to substitute every answer with x and find which one both are equal to each other because both sides of the triangle are equal it is an equilateral triangle so the angles need to be congruent.

Answer:

(For the first two questions I do believe that you will need a protractor to calculate the angles.)

15) $-(\frac{7\pi }{18} )\\$ measures out to -70° in order to display that the angle would be in quadrant IV (the bottom right quadrant.)

The first image attached shows where the angle should be located.

16) $\frac{\pi }{3}$ is equal to 60° (the line you draw will be in quadrant 1 (the top right quadrant))

17) 350° is $\frac{35\pi }{18}$ or 6.11 (the answer depends on the format the professor wants.)

18) 240° is $-(\frac{4\pi }{3})$ radians or -4.19 (I am rounding to the nearest hundredths place the unsimplified answer is −4.18879020...)
