Answer : 4th option

A equation is given to us and we need to find out its graph from the options . The given equation is ,

→ y = -2x + 1

Comparing this equation to the slope intercept form of the line which is y = mx + c , where m is the slope and c is y intercept. We have ,

  • m = -2
  • c = 1

So the equation of the line will cut y axis at (0,1) and will have a negative slope .

  • Since the slope is negative , it will make an obtuse angle in anti clockwise direction with the x axis .

And the graph which satisfies the above conditions is in 4th option .

<u>Hence</u><u> the</u><u> </u><u>correct</u><u> answer</u><u> is</u><u> </u><u>4</u><u>t</u><u>h</u><u> </u><u>option</u><u> </u><u>.</u>

<em>I </em><em>hope</em><em> this</em><em> helps</em><em>. </em>

Question 7
serg [7]

\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}

  • Given - <u>a </u><u>cone</u><u> </u><u>with </u><u>volume</u><u> </u><u>7</u><u>6</u><u>9</u><u>?</u><u>3</u><u> </u><u>ft³</u><u> </u><u>,</u><u> </u><u>having </u><u>a </u><u>height </u><u>of </u><u>1</u><u>5</u><u> </u><u>ft</u>

  • To calculate - <u>radius </u><u>of </u><u>the </u><u>cone</u>

We know that ,

\bold{Volume \: of \: cone =  \frac{1}{3}\pi \: r {}^{2}  h }\\

<u>substituting</u><u> </u><u>the </u><u>values </u><u>in </u><u>the </u><u>formula</u><u> </u><u>stated </u><u>above </u><u>,</u>

\bold{769.3 =  \frac{1}{3}  \times 3.14 \times r {}^{2}  \times 15} \\  \\\bold{\implies r {}^{2}  =  \frac{769.3 \times 3}{3.14 \times 15} } \\  \\\bold{\implies  r {}^{2}  =  \cancel\frac{2307.9}{47.1}}  \\  \\\bold{ \implies \: r {}^{2}  = 49} \\  \\ \bold{\implies \: r = 7 \: ft}

therefore ,

<u>radius </u><u>=</u><u> </u><u>7</u><u> </u><u>cm</u>
