A phone plan charges $15.95 per month and $0.10 for every minute, m, that the phone is used. Mr. Kordemsky wants his phone bill
aleksandrvk [35]

Answer:

The inequality that could be used to model this situation is 15.95+0.10m<40. Also, the number of minutes has to be less than 240.5 for Mr. Kordemsky's phone bill for the month to be less than $40.

Step-by-step explanation:

From the information provided, the inequality would indicate that the phone bill for the month that is equal to the result of the fixed fee plus the price per minute for the number of minutes has to be less than $40, which can be expressed as:

15.95+0.10m<40

Now, you can solve for m:

15.95+0.10m<40

0.10m<40-15.95

0.10m<24.05

m<24.05/0.10

m<240.5

According to this, the answer is that the inequality that could be used to model this situation is 15.95+0.10m<40. Also, the number of minutes has to be less than 240.5 for Mr. Kordemsky's phone bill for the month to be less than $40.

Find all points on the curve that have the given slope.x = 2cost, y= 8sint, slope =-1
tatuchka [14]

Answer:

t_{1} = 0.422\pi \pm \pi\cdot i, \forall \,i \in \mathbb{N}_{O}

t_{2} = 1.422\pi \pm \pi\cdot i, \forall \,i \in \mathbb{N}_{O}

Step-by-step explanation:

In the case of parametric equations, the slope of the curve is equal to:

\frac{dy}{dx} = \frac{\frac{dy}{dt} }{\frac{dx}{dt} }

Where \frac{dx}{dt} and \frac{dy}{dt} are the first derivatives of x and y regarding t. Let be x(t) =2\cdot \cos t and y(t) = 8\cdot \sin t, their first derivatives are found:

\frac{dx}{dt} = -2\cdot \sin t and \frac{dy}{dt} = 8\cdot \cos t

Thus, equation for the slope is:

\frac{dy}{dx} = -\frac{8\cdot \cos t}{2\cdot \sin t}

\frac{dy}{dx} = -\frac{4}{\tan t}

If \frac{dy}{dx} = -1, then:

-1 = -\frac{4}{\tan t}

\tan t = 4

Tangent is positive at 1st quadrant and is a function with a periodicity of \pi, the set of solutions are:

t_{1} = 0.422\pi \pm \pi\cdot i, \forall \,i \in \mathbb{N}_{O}

t_{2} = 1.422\pi \pm \pi\cdot i, \forall \,i \in \mathbb{N}_{O}
