Answer:
Step-by-step explanation:
I believe that what you want to do here is to "differentiate" cos (2x - 1).
We must use the rule for differentiating cos x and also the chain rule, since the input to cos x here is (2x - 1).
(d/dx) is the derivative operator.
(d/dx) (cos x) = -sin x
(d/dx) cos (2x - 1) = - sin (2x - 1) * (d/dx) (2x -1) = -sin (2x - 1)(2) = -2sin (2x - 1)
Answer:
6x ≥ 500
Step-by-step explanation:
I took the test but also it means that in six months, you have to save that amount of money to get exactly or more than 500, so this would be the correct answer!
Answer:
the sales tax rate is 8.59%
Step-by-step explanation:
The computation of the sales tax rate is as follows:
= Tax value ÷ Total taxes
= $10.80 ÷ ($150.52 - $24.72)
= $10.80 ÷ $125.80
= 8.59%
Hence, the sales tax rate is 8.59%
We simply applied the above formula to determine the sales tax rate
The equivalent expression of 14r^4y^6/7r^8y^2 is 2y^4/r^4
<h3>How to determine the equivalent function?</h3>
The expression is given as:
14r^4y^6/7r^8y^2
Start by dividing 14 by 7
2r^4y^6/r^8y^2
Next divide y^6 by y^2
2r^4y^4/r^8
Lastly divide r^4 by r^8
2y^4/r^4
Hence, the equivalent expression of 14r^4y^6/7r^8y^2 is 2y^4/r^4
