Answer:
Option 4
Step-by-step explanation:
-½ means it's -0.5, and then -0.4 then -3/10 = -0.3 and then -0.23, therefore it goes -½, -0.4, -3/10, then -0.23
Since this is not a rational function (with undetermined values in the denominator), but just a normal expression, we can just substitute t with the value toward which the function is approaching. Since this is a continuous function, it doesn't matter from which side it's approaching 0. In this case, let t=0, then sin(4t)=0, cos(4t)=1, then -2 sin^2(4t)+2tcos(4t)=0.
10π=2πr
Divide both sides by 2π
10π/2π=r
Simplify
5=r
Is a decimal number that can be transformed into a fraction or vice versa.
How do you write 39/100 into a decimal form is by simply dividing 39 to 100.
<span>Hence, </span>
1. 39 / 100 = 0.39
<span>0.39 is the decimal form of the given value. </span>
