For no. 62 the answer is A.
Answer:
$515.21
Step-by-step explanation:
Because you're compounding monthly, use the formula:
where A(t) is the amount after the compounding,
P = $500
r = .03 (always in decimal form!)
n = 12 (monthly is every month, and there are 12 months in a year) and
t = time in years
Filling in our given info:
which simplifies to
A(t) = 500(1 + .0025)¹² which simplifies to
A(t) = 500(1.0025)¹² which simplifies to
A(t) = 500(1.030415957) so
A(t) = $515.21
Answer:
15•4 mm
Step-by-step explanation:
using sine rule
a÷ sinA=c ÷sinC
15•4÷sin90=0•5÷sinC
sinC =0•5 × sin90 ÷ 15•4
C =1•9°
A+B+C= 180
90+B+1•9=180
B= 88•2°
b÷sinB = a÷sinA
b÷sin88•2= 15•4÷sin90
b=sin88•2 ×15•4 ÷sin90
b =15•39
to 1 dp
b =15•4 mm
Answer:That is incorrect. 12.8 is greater than 12.68 because .8 is greater than .68
Step-by-step explanation: Since “68” has been placed after the decimal, it is actually “.68” which is less than 1. From here, you have to figure out if .8 or .68 is closer to the number 1 and since .8 is closer, point 12.8 is greater than 12.68
No, because in order to have an exponential function the value ‘e’ should be raised to a value of x. Since ‘e’ is not in this function, is is not an exponential function
