Answer:
y = -(x + 5)² + 4
Step-by-step explanation:
The roots are -3 and -7, so:
y = a (x + 3) (x + 7)
Distribute and complete the square:
y = a (x² + 10x + 21)
y = a (x² + 10x + 25 − 4)
y = a (x² + 10x + 25) − 4a
y = a (x + 5)² − 4a
The vertex is (-5, 4), so a = -1.
y = -(x + 5)² + 4
Answer:
0.6
Step-by-step explanation:
Answer:
Rs.380
Step-by-step explanation:
Given data
Price= Rs 400.
Discount= 5%
Let us find the amount of the discount
=5/100*400
=0.05*400
=Rs. 20
Hence the amount that should be paid for it is
=400-20
=Rs.380
<h2><u>Answer</u> : </h2>
By observing the table we can conclude that for the number of years to travel back double the electricity is required .
i.e. for 5 years = 10 megawatts
therefore, the relationship between x and y can be depicted by the following equation :
Answer:
C)$1,117.61
Step-by-step explanation:
The balance on the credit card is $1187.92 with interest of 12.25%.
r = 12.25% = 12.25/100 = 0.1225
A late fee = $30
Amount = P(1 + r/12)^1 + late fee
Now plug in the given values in to the formula, we get
1187.92 (1 + 0.1225/12) + 30
= 1200.05 + 30
= $1230.05
During the next due date, you pay $125, so the new balance
1230.05 (1 + 0.1225/12) - 125
= $1117.61
Thank you.
