Answer:

d=i√7, -i√7

Step-by-step explanation:

-2d^2 -4=10     add 4 to both sides

-2d^2 = 14        divide each term by -2

d^2= -7              take the square root of each side to get rid of the exponent

d= = √-7           ( put a slash(short line above that = sign ) in the second equal sign)

d = =i√7

Suzie's Slushes has increasing profits each week during the hot summer months. Suzie finds that
Assoli18 [71]

Answer:

Approximately to the nearest cent :

$1856

Step-by-step explanation:

We are told in the above question that:

Suzie's profit increases every month by 30%

We are told that in the first month her profit is $300

Step 1

We are to find the profit for the other weeks:

First week Profit = $300

b) Second week =

$300 × 30/100 = $90

Total amount for the second week= $90 + $300

= $390

c) Third week

$390 × 30/100 = $117

Total amount for the third week = $117 + $390

= $507

d) Fourth week

$507 × 30/100 = $152.1

Total amount for the fourth week = $152.1 + $507

= $659.1

Total Amount of money she would make after 4 weeks =

Profit of the first week + Total Amount for the first week + Total Amount for the second week + Total Amount for the third week + Total Amount for the fourth week

= $300 + $390 + $507 + $659.1

= $1856.10

Approximately to the nearest cent the amount of money will she make in all over 4 weeks is :

$1856
