What are the solutions to the equation and check for extraneous solutions:<br><br> 16=(x-2)^2/3

GuDViN [60]

Answer:

we have x = -62 or x = 66

Step-by-step explanation:

16=(x-2)^2/3

I would take square root first

4 = (x - 2)^ (1/3)

or -4 = (x - 2)^(1/3)

.....

4^3 = x - 2

64 = x - 2

x = 66

or -4 ^3 = x - 2

-64 = x - 2

x = -62

we have x = -62 or x = 66

If Aldo puts 400 into a savings account that paid an interest rate of 5.4 percent What was the total amount in his account at th

Ne4ueva [31]

Answer:

$\$421.60$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=1\ year\\ P=\$400\\ A=?\\r=5.4\%=5.4/100=0.054$

substitute in the formula above

$A=400(1+0.054*1)$

$A=400(1.054)$

$A=\$421.60$

Remember that Interest is equal to

$I=A-P$

$I=\$421.60-\$400=\$21.60$
