Step-by-step explanation:

First factorizat the equation u will het

x^2+2x+3x+6

x(x+2)+3(x+2)

(x+3)(x+2) now

Either

(x+3)=0 or (x+2)=0

x=-3 x=-2

Therefore,possible values of x are -3 and -2

Solve question 3 for <br> 41 points

Sever21 [200]

Answer:

(2)

Step-by-step explanation:

Our logarithmic expression is: $ln(\frac{\sqrt{e} }{y^3} )$ .

Remember the logarithmic property that ln(a/b) = lna - lnb. So, we can write this as:

$ln(\frac{\sqrt{e} }{y^3} )=ln(\sqrt{e} )-ln(y^3)$

Also, we can write square roots as powers of one-half, so √e = $e^{1/2}$ . There's another log property that: $ln(a^b)=b*ln(a)$ . We can apply that here for both the √e and the y³:

$ln(\sqrt{e} )-ln(y^3)=\frac{1}{2} ln(e)-3ln(y)$

Finally, note that ln(e) is just 1, so we have:

$\frac{1}{2} ln(e)-3ln(y)=\frac{1}{2} -3ln(y)=\frac{1-6ln(y)}{2}$

The answer is thus (2).

Find the exact trigonometric ratios for the angle x whose radian measure is given. (if an answer is undefined, enter undefined.)

Inga [223]

Given the angle $\frac{3\pi}{4}$

angle $\frac{3\pi}{4}$ is equivalent to angle 135 degrees and angle 135 degrees is equvalent to angle 45 degrees in the second quadrant, thus sine is positive but cosine and tangent are negative.

$\sin \frac{3\pi}{4} =\sin \frac{\pi}{4} = \frac{1}{ \sqrt{2} } \\ \\ \csc\frac{3\pi}{4}= \frac{1}{\sin\frac{3\pi}{4}} = \frac{1}{\frac{1}{ \sqrt{2} }} = \sqrt{2} \\ \\ \cos\frac{3\pi}{4} =-\cos \frac{\pi}{4} = -\frac{1}{ \sqrt{2} } \\ \\ \sec\frac{3\pi}{4}= \frac{1}{\cos\frac{3\pi}{4}} = \frac{1}{-\frac{1}{ \sqrt{2} }} =- \sqrt{2} \\ \\ \tan\frac{3\pi}{4} =-\tan \frac{\pi}{4} = -1 \\ \\ \cot\frac{3\pi}{4}= \frac{1}{\tan\frac{3\pi}{4}} = \frac{1}{-1} =- 1$

There are 30 students in the school chorus and 12 of these students can stay after school to help prepare the stage for the conc

Angelina_Jolie [31]

The denominator has to be the total number of kids and the numerator is the kids that can stay after school. so 12/30 then simplify. 12/30 divided by 6/6 = 2/5

If a^1/n = ^n √a What is an equivalent form of ^7 √a

Ray Of Light [21]

Answer:

The answer is a^(1/7)

Step-by-step explanation:

The formula is, a^(1/b) = b√a

e.g

2^(3/4) = 4√(2)³

4^(1/2) = √4 ( 2 is not required to write as the symbol, √ , represents 2 or square )
