Kiran read for x minutes, and Andre read for 58 more than that. Write an equation that relates the number of minutes Kiran read

bogdanovich [222]

Answer:

$0.017y=0.017x+0.97$

Step-by-step explanation:

Let us assume that,

number of minutes read by Kiran is = x minutes.

number of minutes read by Andre is = y minutes.

Andre read for 58 minute more than that of Kiran.

Converting minute to hour we get,

$x\text{ minutes}=\dfrac{x}{60}=0.017x\text{ hour}$

$y\text{ minutes}=\dfrac{y}{60}=0.017y\text{ hour}$

$58\text{ minutes}=\dfrac{58}{60}=0.97\text{ hour}$

So the relationship between x and y will be,

$0.017y=0.017x+0.97$

Find the exact values of cos 3 pi/4 radians sin 3 pi/4 radians.

Liula [17]

If you consult the unit circle, you will see that:

$cos(\frac{3\pi}{4}) = -\frac{\sqrt{2}}{2}\\\\sin(\frac{3\pi}{4}) = \frac{\sqrt{2}}{2}$

3pi/4 in degrees is 3pi/4 * 180/pi = 3/4 * 180 = 135 degrees. And please refer to the attachment to how you can obtain the values above.

Now, lets multiply it together.

$-\frac{\sqrt{2}}{2} \cdot \frac{\sqrt{2}}{2} =\\\\-\frac{2}{4} =\\\\ \boxed{\bf{-\frac{1}{2}}}$

So, <span>cos(3pi/4)sin(3pi/4) = -1/2</span>

Which of the following is a binomial?. c2 + c + 6. c2 - 16. -8c. c3 + 4c2 - 12c + 7. Which of the following is a monomial?. c2 +

vlabodo [156]

A monomial has one term, binomial has two terms, trinomial has three terms, and a polynomial has four or more terms.

Therefore, in the first question, c2-16 is the binomial while -8c is the monomial in the second question.
