Well first if he buys 24 a month that equation is 24n n = months and if he already has 523 the explicit rule is an = 24 | 24 | 24 |
--------------------
523
Step-by-step explanation:
d^3=d*d*d=10*10*10=1000
450=c*1000
450/1000=c
9/20=c
Answer:
x = 4
Step-by-step explanation:
14x - 15 + 139 = 180
(Alternate & Supplementary angles)
14x = 56
x = 4
Answer:
b 14.5
Step-by-step explanation:
Ok 25+4=29 then half of 29 is 14.5
2cosx=2sin2x. Sin2x is an identity for 2sinxcos. So 2[2sinxcosx] gives you 4sinxcosx. 2cosx=4sinxcosx. Divide 2cosx on both sides and gives you 2sinx=0 and divide again, sinx=0. Sinx is 0 at 0 and 360 degrees, or pi and 2pi. So thats what x would be. 0,360,pi,2pi.
