Answer:
(x - 7)² + (y - 4)² = 49
Step-by-step explanation:
Given
Equation: x² + y² = 49
Required:
New Equation when translated 7 units right and 4 units up
Taking it one step at a time.
When the equation is translated 7 units right, this implies a negative unit along the x axis.
The equation becomes
(x - 7)² + y² = 49
When the equation is translated 4 units up, this implies a negative unit along the y axis.
(x - 7)² + (y - 4)² = 49
The expression can be further simplified but it's best left in the form of
(x - 7)² + (y - 4)² = 49
The coefficient in this term is x^0
The answer is 216
Step by step
8+7*8+10*7+6*7
48+56+70+42
=216
From the given question we already know that Francois earns a weekly salary of $475 and also a commission of 5.5% on the total amount of goods sold in the week. Francois sold goods worth a total of $700 in the week.
Now we have to calculate first the amount of commission earned from the sales of goods.
Commission earned = (700 * 5.5/100) dollars
= 38.5 dollars.
So francois earns 38 dollars and 50 cents as commission for the goods sold during the week.
Total earning of Francois in the week = (475 + 38.5) dollars
= 513.5 dollars
So the total earning of Francois during the week is 513 dollars and 50 cents.
