The answer to this equation​
12345 [234]

Answer:

x=3

Step-by-step explanation:

We are given the equation

log5x=log(2x+9)

This can be rewritten as

log5x-log(2x+9)=0

Now using the quotient rule for logarithms we can combine these two

log(\frac{5x}{2x+9} )=0

Next we can remove the log by using an inverse operation

10^{log(\frac{5x}{2x+9} )} =10^0\\\\\frac{5x}{2x+9}=1

Now we can solve for x

\frac{5x}{2x+9}=1\\\\5x=2x+9\\\\3x=9\\\\x=3

Find all 6 trig functions given the terminal side goes through point (0,-3)
d1i1m1o1n [39]
So hmm notice the picture below

that's (0, -3)

now, keep in mind, adjacent is 0, opposite is -3, and hypotenuse, or radius, is 3

and recall  sin(\theta)=\cfrac{opposite}{hypotenuse}&#10;\qquad \qquad &#10;% cosine&#10;cos(\theta)=\cfrac{adjacent}{hypotenuse}&#10;&#10;\\ \quad \\\\&#10;% tangent&#10;tan(\theta)=\cfrac{opposite}{adjacent}&#10;\qquad \qquad &#10;% cotangent&#10;cot(\theta)=\cfrac{adjacent}{opposite}&#10;\\ \quad \\&#10;&#10;% cosecant&#10;csc(\theta)=\cfrac{hypotenuse}{opposite}&#10;\qquad \qquad &#10;% secant&#10;sec(\theta)=\cfrac{hypotenuse}{adjacent}
