To be able to buy appliances etc
Answer:
D
Step-by-step explanation:
since p is an odd number choice C can't be the answer because 4 is even number
Q is an even number so that choice B can't be answers because 3 is an odd number .
and for A 6 isnot a prime number so that it proves tim is correct.
but when we see D 2 is a prime number so that it shows tim is wrong.
Answer:
a. √64=8
b. ∛1000=10
Step-by-step explanation:
64=8^2 Therefore, √64=8
1000=10^3 As a result, ∛1000=10
64=4^3 but each number can only be used once, so this is not possible answer.
Answer:
119.05°
Step-by-step explanation:
In general, the angle is given by ...
θ = arctan(y/x)
Here, that becomes ...
θ = arctan(9/-5) ≈ 119.05°

<em>Comment on using a calculator</em>
If you use the ATAN2( ) function of a graphing calculator or spreadsheet, it will give you the angle in the proper quadrant. If you use the arctangent function (tan⁻¹) of a typical scientific calculator, it will give you a 4th-quadrant angle when the ratio is negative. You must recognize that the desired 2nd-quadrant angle is 180° more than that.

It may help you to consider looking at the "reference angle." In this geometry, it is the angle between the vector v and the -x axis. The coordinates tell you the lengths of the sides of the triangle vector v forms with the -x axis and a vertical line from that axis to the tip of the vector. Then the trig ratio you're interested in is ...
Tan = Opposite/Adjacent = |y|/|x|
This is the tangent of the reference angle, which will be ...
θ = arctan(|y| / |x|) = arctan(9/5) ≈ 60.95°
You can see from your diagram that the angle CCW from the +x axis will be the supplement of this value, 180° -60.95° = 119.05°.
