Step-by-step explanation:
oh, come one ! you can literally see that one ...
a full rotation on a clock is a full circle and stands therefore for 360°.
for the minute hand these 360° represent 60 minutes.
4 minutes of 60 is a fraction, a ratio, and the same ratio applies then also to 360°.
4/60 = 1/15
360 × 1/15 = 24°
so, 4 minutes represent 24°.
Answer:
8
Step-by-step explanation:
64 / 8 = 8
Answer:
a
Step-by-step explanation:
it is all doubles
<span>3x''+3x'+7x = 9sin 3t - to begin
then </span>Use the method of undetermined coefficients
Then you need to find <span><span>x′p</span> and <span>x′′p and sub them into equation, that will help you to solve A and B.
</span></span>
And finally you will have this :
<span><span><span>3<span>x′′</span>+3<span>x′</span>+7x=9sin(3t)</span><span>[−27Asin(3t)−27Bcos(3t)]+[9Acos(3t)−9Bsin(3t)]+[7Asin(3t)+7Bcos(3t)]</span><span>=9sin(3t)</span><span>(−20A+9B)sin(3t)+(−20B+9A)cos(3t)=9sin(3t)</span></span></span>
Answer:
-22*F
Step-by-step explanation:
The answer is -22*F because you are subtracting -7*F from -29*F.
