Personally for proving questions especially trigo, i reckon u memorise all of the formulas, esp double angle and half angle.

also, for other types of proving qn like prove d = 1/2 in an a.p, u can always go back to your basics, which is U1 + d = U2.

but, i would say that as long as u practice a lot of questions u should be able to recognise how to prove the questions

The figure shows the front side of a metal desk in the shape of a trapezoid.
Alenkinab [10]

Answer:

Area of trapezoid is 16ft^2.

Therefore, option 2nd  is correct.

Step-by-step explanation:

We have been given both the sides a=3 and b=5.

And height that is h=4

We will use the formula find the area of trapezoid is:

\frac{a+b}{2}\cdot h

Substitute the formula we get:

\frac{3+5}{2}\cdot 4

\Rightarrow \frac{8}{2}\cdot 4

\Rightarrow 16.

Area of trapezoid is 16ft^2.

Therefore, option 2nd  is correct.

What are the potential solutions of log4x+log4(x+6)=2?
lions [1.4K]

The potential solutions of log_4x+log_4(x+6)=2 are 2 and -8.

<h3>Properties of Logarithms</h3>

From the properties of logarithms, you can rewrite logarithmic expressions.

The main properties are:

  • Product Rule for Logarithms - log_{b}(a*c)=log_{b}a+log_{b}c
  • Quotient Rule for Logarithms - log_{b}(\frac{a}{c} )=log_{b}a-log_{b}c
  • Power Rule for Logarithms - log_{b}(a^c)=c*log_{b}a

The exercise asks the potential solutions for  log_4x+log_4(x+6)=2. In this expression you can apply the Product Rule for Logarithms.

                                  log_4x+log_4(x+6)=2\\ \\ x*(x+6)=4^2\\ \\ x^2+6x=16\\ \\ x^2+6x-16=0

Now you should solve the quadratic equation.

 

 Δ=b^2-4ac=36-4*1*(-16)=36+64=100. Thus, x will be x_{1,\:2}=\frac{-6\pm \:\sqrt{100} }{2\cdot \:1}=\frac{-6\pm \:10}{2}. Then:

x_1=\frac{-6+10}{2}=\frac{4}{2} =2\\ \\ \:x_2=\frac{-6-10}{2}=\frac{-16}{2} =-8

The potential solutions  are 2 and -8.

The question is below:​
Sonja [21]

Answer:

x = 19.5, RQS=43

Step-by-step explanation:

It is important to note that RQS and TQS are supplementary, meaning their angles will add up to 180. Knowing this, we can create and solve the equation to find x..

(2x+4) + (6x+20) = 180

8x + 24 = 180

8x = 156

x = 19.5

Now that we know the value of x, we can substitute it into the equation for RQS, 2x+4.

2(19.5)+4

39+4

43

Hope this helped!
