Answer:

Cos 74°= Sin 16°

Sin 20°= Cos 70°

Sin A°=Cos (90°- A°)

Step-by-step explanation:

This is because the three pairs are complementary i.e they add up to 90° and in trigonometric ratios, complementary ratios are equal.

What is the simplified form of x+9/2x+3+x+4/x+2?
Mice21 [21]
The answer is C because multiply and divide by (x+2)(2x+3) 
= ( (x+9)(x+2) + (x+4)(2x+3) ) ( (x+2)(2x+3)) 
= ( (x^2+11x+18) + (2x^2+11x+12) ) / ( 2x^2+7x+6) 
= (3x^2+22x+30) / (2x^2+7x+6)

Express the given quantity as a single logarithm:
Naya [18.7K]
Hello,

1) Conditions:

 x+2>=0==>x>-2
  x>=0
So x>=0

1/5 ln(x+2)^5 +1/2 [ln x -ln(x^2+3x+2)^2]
=ln(x+2)+ ln√x - ln(x+1)(x+2)
=ln (x+2)+ln(\dfrac{ \sqrt{x} }{(x+1)(x+2)}) \\\\

= ln(\dfrac{ \sqrt{x} }{x+1} )

What is the equation of the line x–3y=18 in slope-intercept form? Drag and drop the appropriate number, symbol, or variable to e
Sunny_sXe [5.5K]
Simple...

you have: x-3y=18

You want to convert it into slope-intercept form or y=mx+b form-->>>

x-3y=18

Isolate the variable-->>

x-3y=18
-x      -x

-3y=-x+18

Now simply divide...

\frac{-3y}{-3} = \frac{-x+18}{-3}

y=\frac{1}{3}x -6

Thus, your answer.

Jed places the letters A, B, C, D, E, F, G, H and I into a bag and picks 2 at random. What is the probability he chooses at leas
Nadya [2.5K]

Answer:

<h2>0.583333333333</h2>

Step-by-step explanation:

we have 9 letters

3 vowels: A , E , I

6 consonant: B, C, D, F, G , H

Consider the event V : «choosing at least 1 vowel»

\Longrightarrow \overline{V} \  \colon \  \text{choosing 2 consonant}

p(V) =1-p\left( \overline{V} \right)  =1-\frac{C^{2}_{6}}{C^{2}_{9}}=0.583333333333
