Given expression :

  • y = kx

let's plug the value of x as 0.4 and y as 20 in the given equation :

  • 20 = 0.4k

  • k = 20 ÷ 0.4

  • k = 50

correct choice - D. 50

\\ \sf\longmapsto y=kx

\\ \sf\longmapsto k=\dfrac{y}{x}

  • put values

\\ \sf\longmapsto k=\dfrac{20}{0.4}

\\ \sf\longmapsto k=50

Write each as a decimal. Round to the thousandths place.<br> 9) 78.4%<br> 10) 29%<br> Help
fomenos

Answer:

(a) 78.4\% = 0.784

(b) 29\% =0.290

Step-by-step explanation:

Required

As a decimal to nearest thousandth

Solving (a): 78.4%

78.4\%

Express as fraction

78.4\% = \frac{78.4}{100}

Solve fraction

78.4\% = 0.784 ----- This is already in thousandth place

Solving (b): 29%

29\%

Express as fraction

29\% =\frac{29}{100}

Solve fraction

29\% =0.29

Approximate

29\% =0.290

Verify sin2θ/1+cos2θ =tanθ
Andrej [43]

Answer:

LHS.= Sin 2x /( 1 + cos2x )

We have , sin 2x = 2 sinx•cosx

And. cos2x = 2cos^2 x - 1

i.e . 1+ cosx 2x = 2cos^2x

Putting the above results in the LHSwe get,

Sin2x/ ( 1+ cos2x ) =2 sinx•cosx/2cos^2x

=sinx / cosx

= Tanx

.•. sin2x/(1 + cos2x)= tanx
