Remember the pythagorean theorem.
a^2 + b^2 = c^2
The complex number is a+bi, the absolute value is 'c'
Answer:
The answer to your question is 2.8 x 10¹¹
Step-by-step explanation:
Data
1 tree produces 2.6 x 10² pounds of oxygen/year
number of trees = 3.9 x 10¹¹
pounds of oxygen per day = ?
Process
1.- Divide the pounds of oxygen by 365, to get the pounds of oxygen per day.
2.6 x 10² / 365 = 0.712
2.- Multiply the number of trees by the pounds of oxygen per day
3.9 x 10¹¹ x 0.712 = 2.8 x 10¹¹ pounds of oxygen
Answer:
Blablabka
Step-by-step explanation:
Blablabla
y = her salary,
m = rate of commission,
x = amount of merchandise sold
b = monthly base pay
sets of data to calculate the formula
(500, 405) and (900, 489)
use the slope formula to find m:
(489 - 405) / (900 - 500)
m= 84 / 400 = 0.21 (21% commission)
find the base pay by substituting known values for x,y, and m, then solve for b:
405 = (0.21)(500) + b
405 = 105 + b
b = 300
now we know the equation for her salary is:
y = 0.21x + 300
To find the salary when she sells $1,700 worth of merchandise, put 1700 for x and solve for y:
y = 0.21(1700) + 300 = 657
