Evaluate the limit of ((1/4 + 1/x)/(4+x)) as x -> -4​
photoshop1234 [79]

Hello from MrBillDoesMath!

Answer:

-1/16

Discussion:

Rewrite   ((1/4 + 1/x)/(4+x))  as

(1/4 + 1/x)  *  (1/(4+x)) =                 => put num. over common denom,

( (x+4)/4x) *  (1/(4+x)) =                 => cancel (x+4) from num. and denom.

(1/4x)

So as x ->-4, (1/4x) approaches ( 1/ ( 4 * (-4) )   ) = -1/16

Thank you,

MrB

Ahat [919]

Answer: $58,088.57

Step-by-step explanation:

The investment is compounded weekly so you need to change the parameters of the equation to a weekly figure:

Interest rate is yearly so:

= 3.75%/52

= 3.75/52% per week

Number of periods is 4 years so:

= 4 * 52

= 208 weeks

Future value in 4 years is:

= 50,000 * ( 1 + 3.75/52%)²⁰⁸

= $58,088.57

2470.28277045 To 3 decimal places
jeka57 [31]

To run the these figures to 3 decimal places

you need to count from the digit after the decimal point until you reach the 3rd number which is 2

so now the answer is 2470.283

This is because the decimal point lies between 2 and 7 and since 7 is great than 5 we add 1 to the 2 making it 3
