ar(n)=total a is the first number which is 7000 r is the common ratio which is 100%+2%=102 102 divided by 100 giving u 1.02(interest) so ar(n)=sum n is written as power.....and is the number of years so 7000*1.02(n)=(7000+420) 1.02(n)=7420/7000 1.02(n)=1.06 log10 1.02(n)=log10(1.06) ( multiply log10 with both) n=log10(1.06)/log10 (1.02) u get 2.94 which is round off to 3 so 3 years.. hope This helps :)
Answer:
since the decay rate constant of0.0 250 min.
hence the time required for the sample to decay to one forth of it's initial value is
Step-by-step explanation:
The constant proportionality is the proportionality of 59. Because it is the price, you just move the decimal point two places over to the left.
If you do this correctly you will get .59
Answer:
No.The answer should be -4.1
Step-by-step explanation:
1+4(3x-10)-12
5(3x-10)-12
15x-50-12
15x-62
x=-62/15
x=-4.1
Answer:
a=1 and b=13
do you need the working out?
