Answer:
0.9
Solution:
First remember that a negative times a negative is positive (-)(-)=(+) and that a positive times a negative is a negative (+)(-)=(-)
Solve
-1.424+2.9-0.576=0.9
The correct answer solved by indices and the value of the expression (-3.69)⁰ is: 1
What is indices based expression?
In mathematics, the indices expression are those whose base values are either same or constant can be solved with this method. This property states that the when the power is zero for any value or variable, then the output is 1.
According to the question, the given data states that the value of the expression (-3.69)⁰ can be calculated with the concept of indices:
As per indices property: any value or variable whose power is zero, can be consider as 1 in the answer.
Therefore, the value of the expression (a)⁰ = (-3.69)⁰ = 1.

Answer:
a. k = 24 b. y =
Step-by-step explanation:
a. Find the value of the constant k
Since is a solution of d²y/dt² -10dy/dt + ky = 0, then must satisfy the equation.
So, d²y/dt² = and dy/dt =
So, d²y/dt² -10dy/dt + ky = 0
- 10() + k() = 0
- + = 0
- + = 0
- = -
So, k = 24
b. Find the general solution to this equation.
Since k = 24, our equation is
d²y/dt² -10dy/dt + 24y = 0
The characteristic equation is thus
m² - 10m + 24 = 0
Factorizing this we have
m² - 6m - 4m + 24 = 0
m(m - 6) - 4(m - 6) = 0
(m - 6)(m - 4) = 0
m - 6 = 0 or m - 4 = 0
m = 6 or m = 4
Since we have real roots for the characteristic equation, then, the general solution is
y =
