4 (3a+2) = 5
12a + 8 = 5
12a = -3
a = -3/12 = -1/4
a = -1/4

Answer:

a= -1/4

Step-by-step explanation:

4(3a+2)=5

distribute the 4 to both 3a and 2

12a+8=5

subtract 8 on both sides

12a=-3

divide by 12 on both sides

a= -1/4

Suppose we want to choose 5 objects,without replacement from 16 distinct objects
lesya692 [45]

Answer:

4368 ways

Step-by-step explanation:

We want to choose 5 objects,without replacement from 16 distinct objects.

We can use combination in this case. The formula for the combination is given by :

_{n}C_r=\dfrac{n!}{r!(n-r)!}

We have, n = 16 and r = 5

So,

_{16}C_5=\dfrac{16!}{5!(16-5)!}\\\\_{16}C_5=\dfrac{16!}{5!11!}\\\\=4368

So, there are 4368 ways in which we want to choose  5 objects,without replacement from 16 distinct objects.

Pls help i don’t know how to do this
algol [13]

Answer: \displaystyle\\\frac{2\pi }{3},\ \frac{5\pi }{3}  .

Step-by-step explanation:

\displaystyle\\tan\theta=-\sqrt{3}\ \ \ \  0\leq \theta\leq 2\pi \\\theta =\frac{2\pi }{3}+\pi N\ \ \ (N=0,\ 1,\ 2,\ 3\ ...)\\ N=0\\\theta=\frac{2\pi }{3} +\pi *0\\\theta=\frac{2\pi }{3}\ \ \ \ ( 0\leq \theta\leq 2\pi)\\ N=1\\\theta=\frac{2\pi }{3}+\pi *1 \\\theta=\frac{2\pi }{3} +\pi \\\theta=\frac{2\pi +3\pi }{3} \\\theta=\frac{5\pi }{3} \ \ \ (  0\leq \theta\leq 2\pi)\\

N=2\\\theta=\frac{2\pi }{3}+2\pi \\ \theta=\frac{2\pi +3*2\pi }{3}\\ \theta=\frac{2\pi +6\pi }{3} \\\theta=\frac{8\pi }{3} \\\theta=2\frac{2}{3} \pi \ \ \ \  (\notin0\leq \theta\leq 2\pi).\\
