armand deposited $389.42 in a savings account that earns 3.2% simple interest. what is armand’s account balance after 7 years?

1 answer:

7 0

Okay so since we have $389.42 to start with, we will multiply that by 3.2% which gives us roughly $12.46. Knowing that he will get an additional $12.46 per year, we multiply 12.46 by 7, giving us $87.22. Now, we just add 87.22 to 389.42, which is 476.64. Therefore, Armand has $476.64 as his account after 7 years.

What are the vertical asymptote(s) of y= (x-6)/(x+8) (x-7)

White raven [17]

Answer:

x = -8 and x= 7

Step-by-step explanation:

recall that for a rational expression, the vertical asymptotes occur at x-values that causes the expression to become undefined. These occur when the denominator becomes zero.

Hence the asymptototes will occur in x-locations where the denominator , i.e

(x+8)(x-7) = 0

solving this, we get

(x+8) = 0 ----> x = -8

(x-7) = 0 ------> x = 7

hence the asymptotes occur x = -8 and x= 7

A surveyor measures the length of a surveying chain containing 1000 chain links. The length is 0.0533km. What is the length of a

Leya [2.2K]

Answer:

length of a single chain link = 5.33 cm

Step-by-step explanation:

Given data: chain contained 1000 chain links

total length was 0.0533km

1km = 1000m

1m = 100cm therefore 1km = 100000cm

total length in cm = 0.0533* 100000

total length in cm = 5330 cm

length of a single chain link = 5330/1000

length of a single chain link = 5.33 cm
