90 in terms of pi is .
<u>Step-by-step explanation:</u>
We know that ,
- Degrees are a unit of angle measure. A full circle is divided into 360 degrees. For example, a right angle is 90 degrees. A degree has the symbol ° and so ninety degrees would written 90°. Another unit of angle measure is the radian.
- The radian is the SI unit for measuring angles, and is the standard unit of angular measure used in many areas of mathematics. The length of an arc of a unit circle is numerically equal to the measurement in radians of the angle that it subtends; one radian is just under 57.3 degrees.
We have to convert 90 in terms of pi i.e. degree to radians:
⇒

Therefore, 90 in terms of pi is .
Answer:
domain of y = sqrt (x+4) is [-4, +inf)
Step-by-step explanation:
[-4, +inf), -4 is included because sqrt(-4 + 4) is defined but is undefined at the points from (-inf, -5].
My guess is C because that’s what makes the most sense
Answer:
A.10
B.10
C. 10,000
D. 8 hours
Step-by-step explanation:
Firstly, we should know that the numbers are labeled 0-9.
A. 10 digits
B. We already took one digit , but we still have 10 choices left again as numbers can be repeated.
C. For the first number, we have 10C1 choices since we are selecting 1 out of 10 numbers. This is the case for all the 3 renaming numbers. Hence the total number of possible passwords are
(10C1)^4 = 10,000 possible password combinations
D. That is (10,000*3)/60 in minutes = 500 minutes = 500/60 = 8.3333 , approximately 8hrs
Answer:
(-1, 1), (-1, 2), (0, 1)
Step-by-step explanation:
It appears as though letter designations have become confused. If not, your question answers itself, as a, b, c are given and you're asking for a, b, and c.
___
Reflecting the given points across the line y=-x transforms them like this:
(x, y) ⇒ (-y, -x)
That is, you swap the coordinates and negate them both. The result will be as shown above and in the attachment.
