Always simplify expressions in the order of PMDAS
(Parenthesis, Multiplication, Division, Addition, Subtraction)
(4-1) = (3)
[(1+6) + 2] = [7 + 2] = (9)
(3)x(9) = 27
The answer is 27
8-2(6-4:2)
8-2(6-2)
8-2*4
8-8=0
Its b, no matter what, he has to pay 18 dollars which effects the y intercept
We are given with the equation y"+ 9 y = t^2 * e^3 t + 6 and asked to determine the general solution to this equation. we convert the equation into r^2 + 9 = 0. The solution to this equation is r = +/- 3i. This solution converted to trigonometric function is equivalent to <span>y</span>= <span>C1 </span>cos3t + <span>C2 </span>sin<span>3t. </span>
Answer:
4√(5) i
Step-by-step explanation:
√(-80) = √(80)i
=√(16) √(5) i
= 4√(5) i
where the operator i = √-1
