Find sin(u/2) if tan(u)=-7.721 and u is in quadrant 4

morpeh [17]

Answer:

.6601

Step-by-step explanation:

to find u, which we assume is an angle of course, we can take arctan of both sides. so arctan(-7.721) = -1.4420. this angle is in quadrant 4, but it is not in the range. In this instance you just go around the circle again, or add 2pi, which gets us 4.8412. You can check and you get the same answer if you take the tangent of either.

So now we have a number in the appropriate range in the appropriate quadrant. That means we have the correct angle. The question asks what is sine of that angle cut in half. so sin(4.8412/2), which gets you your answer. let em know if something didn't make sense.

An equipment rental company charges a flat rate of $25,plusc$13 per day for insurance.kyle has $121.write an inequality to repre

Sergio [31]

13d+25≤121 represent the inequality to find the number of days.

Step-by-step explanation:

Flat rental fee of equipment = $25

No. of days = d

Per day fee = $13

Amount Kyle has = $121

According to given statement,

$13d+25\leq 121$

As the amount is $121, therefore, the total cost can either be a total of $121 or less.

13d+25≤121 represent the inequality to find the number of days.

63% of what number is 252

storchak [24]

Answer:

We have, 63% × x = 252

or,

63/100 × x = 252

Multiplying both sides by 100 and dividing both sides by 63,

we have

$x = 252 \times \frac{100}{63 }$

x = 400
