We are asked to give the exact value of <span>cos(arcsin(one fourth)). In this case, we shift first the setting to degrees since this involves angles. we determine first arc sin of one fourth equal to 14.48 degrees. then we take the cos of 14.48 degrees equal to 0.9682. Answer is 0.9682.</span>
F(4)=(4-1)+2*4=11...
This seems a bit too easy though, did you mean f(n)=f(n-1)+2n ? In this case :
f(1)=16
f(2)=16+2*2=20
f(3)=20+2*3=26
f(4)=26+2*4=34
Answer:
4
Step-by-step explanation:
(A+B+C+D) / 4 = 10 .... average=sum/number of item
(A+B+C)/3 = 3D ... average of first 3 (A,B,C) is triple of forth (D)
A+B+C = 9D
(9D+D)/4=10
10D = 40
D = 4
