Each day, a salesperson earns $25 plus 5% of their total sales for the day. The salesperson's goal is to earn more than $50 on T
Lera25 [3.4K]

The true statement about the inequality is that Total sales per day is greater than $250

<h3>How to write and solve inequality equation?</h3>

  • Total sales per day = x

  • Amount earned per day = 25 + 5% of x

= 25 + 0.05x

  • Thursday = 4th day of the week

The inequality:

4(25 + 0.05x) > 50

100 + 0.2x > 50

100 - 50 > 0.2x

50 > 0.2x

x > 50/0.2

x > $250

331 students went on a field trip. six buses were filled and 7 students traveled in cars. How many were in each bus? Write an eq
mart [117]
So this problem would be written as this(:

so you start with 331 students together, but then you lose 7 who travel in the cars.

331-7=324

then it would be 324 divided by the 6 buses. that would look like this

324/6
that equals 54.
so in conclusion the answer is 54 students went into each bus:) hope that helps you!

What is the derivative of the following function? f(x) = 4x^6/cos^5(x)
KIM [24]

Answer:

f'(x) = \frac{24x^{5} \cos x + 20x^{6}\sin x}{\cos^{6}x }

Step-by-step explanation:

We have to find the derivative of the following function:

f(x) = \frac{4x^{6} }{\cos^{5} x }

Now, differentiating both sides with respect to x we get,

f'(x) = \frac{\cos^{5}x (24x^{5}) - 4x^{6}(5\cos^{4}x )(- \sin x)}{(\cos^{5}x )^{2}}

⇒ f'(x) = \frac{ 24x^{5} \cos x + 20 x^{6}\sin x}{\cos^{6}x } (Answer)

{Since, we know that, \frac{d(mx^{n} )}{dx} = m \times n x^{(n - 1)} and \frac{d(\cos^{n} x)}{dx} = n \cos^{(n - 1)} x(- \sin x) }
