Current temperature = -2°C
Rise in temperature = 15°C
New temperature = (-2 + 15)°C = 13°C
Given that the roots of the equation x^2-6x+c=0 are 3+8i and 3-8i, the value of c can be obtained as follows;
taking x=3+8i and substituting it in our equation we get:
(3+8i)^2-6(3+8i)+c=0
-55+48i-18-48i+c=0
collecting the like terms we get:
-55-18+48i-48i+c=0
-73+c=0
c=73
the answer is c=73
Answer: $5,828.28
<u>Step-by-step explanation:</u>
Use the Compound Interest formula: where
- A is the accrued amount (balance)
- P is the principal (initial amount invested)
- r is the interest rate (in decimal form)
- n is the number of times compounded each year
- t is the time of the investment (in years)
Given: P = 4,900
r = 3.5% (0.035)
n = 2
t = 5
Answer:
Yes
Step-by-step explanation:
To see if (2,0) works as a solution to the systems of equations, we plug in the values of x and y and simplify. If the results are equal, then (2,0) is a solution.
3x + y = 6:
-
-
-
- (2,0) is a solution to this equation.
3x - y = 6:
-
-
-
- (2,0) is a solution to this equation.
Therefore, the answer is yes, it does work as a solution.
