The answer is 280 use a calculator
Answer:6 = 6x -2
Step-by-step explanation: Solve for the first variable in one of the equations, then substitute the result into the other equation.
In the scenario above, the best method to use is A by the Addition of a chemical reagent to the pond to neutralize the pesticide. This chemical reagent removes the pesticide at the rate of 11 gal/hr.
<h3>What removes pesticides from water?</h3>
Pesticides can be removed from ponds water via chemical reagent through Chemical degradation and other ways.
Note that the first option is useful as the Addition of a chemical reagent to the pond to neutralize the pesticide because there are lot of chemical against that can eat up other chemicals that are harmful to the pond.

Answer:
One root is 90 degrees or π/2 radians.
Drawing a graph we get all the roots:
nπ and π(n - 1/2)
Step-by-step explanation:
Sin^3A.cos A + Cos^ 3 A = Cos A
Divide through by cos A
sin^3A + cos^2A = 1
sin^3 A = 1 - cos^2 A
sin^3 A = sin^2 A
sin A = 1
So one root is A = 90 degrees or π/2 radians.
Checking this result:
(sin 90^3 * cos 90 + (cos 90)^3 = 1 * 0 + 0 = 0
cos 90 = 0
So this is correct..
