Answer:

<h3> </h3><h3>\boxed{ -  \frac{2}{5} }</h3>

Option B is the correct option.

Step-by-step explanation:

\mathrm{ -  \frac{4}{5}  \div 2}

\mathrm{dividing \: a \: negative \: and \: a \: positive \: equals \: a \: negative \:. \: ( - )  \div ( + ) = ( - )}

\mathrm{ -  \frac{4}{5}  \div 2}

\mathrm{dividing \: is \: equivalent \: to \: multiplying \: with \: the \: reciprocal}

\mathrm{ -  \frac{4}{5}  \times  \frac{1}{2} }

\mathrm{reduce \: the \: numbers \: with \: G.C.F \: 2}

\mathrm{ -  \frac{2}{5} }

Hope I helped!

Best regards!

kondaur [170]

Answer:

W(t)=5.5t+79.5.

Step-by-step explanation:

Please consider the complete question.

A young sumo wrestler decided to go on a special high-protein diet to gain weight rapidly. He gained weight at a rate of 5.5 kilograms per month. After 11 months, he weighed 140 kilograms. Let W(t) denote the sumo wrestler's weight W(measured in kilograms) as a function of time t (measured in months).  

Since wrestler gained weight at a rate of 5.5 kilograms per month, so slope of line be 5.5.

Now, we will use point-slope form of equation as:

y-y_1=m(x-x_1), where,

m = Slope

(x_1,y_1) = Given point on the line.

Upon substituting coordinates of point (11,140) in above formula, we will get:

y-140=5.5(x-11)

y-140=5.5x-60.5

y-140+140=5.5x-60.5+140

y=5.5x+79.5

Therefore, our required function would be W(t)=5.5t+79.5.

Find the exact value of tan(sin^-1((-12/13))
lidiya [134]

Answer:

<em>2.399</em>

Step-by-step explanation:

Given the trigonometry expression:

tan(sin^-1((-12/13))

We are to find the exact value

tan(sin^-1((-12/13)) = tan(sin^-1((-0.9231))

tan(sin^-1((-12/13)) = tan(-67.38)

Also note that tan(-theta) = -tan theta

tan(-theta) = -tan67.38

tan(-67.38) = -2.399

<em>The exact value is 2.399</em>
