Andre45 [30]

Answer:

180 different combinations

Step-by-step explanation:

To find the number of different combinations possible, We first find the number of possibilities for each place, and then multiply all possibilities.

Number of possibilities for president: 5

Number of possibilities for vice-president: 6

Number of possibilities for secretary: 2

Number of possibilities for treasurer: 3

Number of different combinations: 5*6*2*3 = 180

(We can form 180 different groups of 1 president, 1 vice-president, 1 secretary and 1 treasurer)

7. (07.02 MC)

Evgesh-ka [11]

Answer:

$y = 52.02$

Step-by-step explanation:

Given

The attached triangle

Required

Find y

Taking y as a reference , we have:

$Adjacent = 8$

$Hypotenuse = 13$

So:

$\cos(y) = \frac{Adjacent}{Hypotenuse}$

This gives

$\cos(y) = \frac{8}{13}$

$\cos(y) = 0.6154$

Take arccos of both sides

$y = \cos^{-1}(0.6154)$

$y = 52.02$

$(a+b)^2=a^2+2ab+b^2 \\ \\ \sqrt{2-7x} - \sqrt{x+3} =3 \\ (\sqrt{2-7x})^2 =(3 + \sqrt{x+3})^2\\2-7x=9+6\sqrt{x+3}+x+3 \\ 2-7x-9-x-3=6\sqrt{x+3} \\ (-8x-10)^2=(6\sqrt{x+3})^2 \\64x^2+160x+100=36(x+3) \\ 64x^2+160x+100=36x+108\\ 64x^2+160x-36x+100-108=0 \\ 64x^2+`124x-8=0 \\ 4( 16x^{2} +31x-2)=0 \\$
$16x^{2} +31x-2=0 \\(x-2)(16x-1)=0 \\ x+2=0 \\ x=-2 \\ 16x-1=0 \\ x= \frac{1}{16}$

$\sqrt{2-7 \cdot\frac{1}{16} } - \sqrt{\frac{1}{16} +3} \neq 3 \\ x=-2$
