Answer:
-7k + 14
Step-by-step explanation:
(k² - 7k + 2) - (k² - 12)
k² - 7k + 2 - k² + 12
k² - k² - 7k + 2 + 12
-7k + 14
Good for chelsa. Whats the question here lol. comment it so I can help
Answer:
0.5 A
Step-by-step explanation:
Hi,
I believe the question is incomplete. However, as per the information provided:
The simplest way to calculate the Current (unit is Amperage), is understanding the relationship between the three: Power, Voltage and Current.
<em>(Quick Tip: </em><em>W=AV</em><em>; where W -> Watts (Power), A -> Ampere (Current), V -> Volts (Voltage))</em>
Using the formula we calculate the Ampere:
W = A x V
60 = A x 120
60/120 = A (We divide the equation be 120)
0.5 = A (Simply reduce the fraction 60/120 = 1/2 = 0.5)
Tip:
Given are several terms in a quadratic pattern:
a1 = ?
a2 = 1
a3 = -16
a4 = ?
a5 = -14
let:
x y
1 ?
2 1
3 -16
4 ?
5 -14
considering the 2nd term and 3rd term, we can determine a quadratic function:
y = -17x + 35
therefore,
a1 = 18
a4 = -33
