Answer:
2.25
Step-by-step explanation: Replace the z with the value given (-18) and then multiply that by 1.1 you can then add it to 21.3 and then do the exponent
H=14 for this particular instance so:
14=2+29t-16t²
14-2=2-2+29t-16t²
12=29t-16t²
0=-16t²+29t-12
that's as factored as possible so you should use the quadratic formula for the rest and check for extraneous answers
B
If you need help to visualize it, think of 48 circles. Circle groups of 6 circles. Grouping the circles, is the same as plain dividing 48 by 6 without the pictures.
To answer the
problem, you must the formula in finding the interest and after that we will
add it to the principal to get the future value.
The formula is: I =
Prt
Interest = Principal
x rate x time
= 200 x 0.062 x 6/12
= $6.2 is the interest for 6 six months.
Future Value =
Principal + Interest
FV = 200 + 6.20
FV = $206.20 is the amount to be paid at the end of 6 months.
