Answer:
23°
Step-by-step explanation:
The angle a vector makes relative to the +x axis is found as ...
α = arctan(y/x) = arctan(4.30/10.3) ≈ 22.66°
The angle is about 23°.
__
<em>Additional comment</em>
This vector resides in the first quadrant, so no adjustment of the angle is needed. In other quadrants, 180° may need to be added or subtracted from the angle given by the arctan function to arrive at the correct value. (Some calculators and spreadsheets have an ATAN2(x, y) function that takes signs into account.)
Answer:
0.4 l of purple sand
Step-by-step explanation:
<u>Volume to be filled in:</u>
<u>Red sand</u>
<u>Blue sand</u>
- 35 centiliters = 35*10 ml = 350 ml
<u>Yellow sand</u>
- 2.5 deciliters = 2.5*100 ml = 250 ml
<u>Total volume filled:</u>
- 1000 + 350 + 250 = 1600 ml
<u>Purple sand needed:</u>
- 2000 - 1600 = 400 ml = 0.4 l
<u>Answer is</u> 0.4 l of purple sand required
Answer:
- 66
Step-by-step explanation:
Evaluate g(- 4) then substitute the value obtained into f(x) , that is
g(- 4) = - 2(- 4)² = - 2 × 16 = - 32, then
f(- 32) = 2(- 32 - 1) = 2 × - 33 = - 66
