Answer:

-3

Step-by-step explanation:

You would find what the answer to (5•3) is then subtract that answer with 18. So it would be 15-18=-3

Answer:

The answer is -3

Step-by-step explanation:

The answer is -3 because of the order of operations PEMDAS (parenthesis, exponent, multiplication/division, addition/subtraction)

Therefore, you would multiply the two numbers inside the parenthesis first, which would give you 15-18, and from there you can subtract 18 from 15 which would give you -3.

at 111111:55\text{ p.m.}55 p.m.55, start text, space, p, point, m, point, end text, thomas ties a weight to the minute hand of a

Ahat [919]

The trigonometric function's formula, which simulates the torque (tau) that the weight applied t minutes after Thomas attached it is

$3 Sin (\frac{2\frac{22}{7} }{60} (t-51))$

The angular speed of the minutes hand is

$w = \frac{2 (\frac{22}{7}) }{60}$ rad/min

Following the application of weight, the torque as a function of time t is,

$t= t_{0} sin (w (t-5) min)\\ = (3 Nm) sin ((\frac{2 (\frac{22}{7} }{60} ) rad/min (t-5) min)$

$= (3 Nm) sin ( \frac{2 (\frac{22}{7} }{60} (t-5) rad ) \\= 3 sin (\frac{2 \frac{22}{7} }{60} (t-5)$

<h3>What is torque ?</h3>

Torque, which is also known as the moment of a force, is the propensity of a force to rotate the body to which it is applied. Force (F) x Distance (r) = Torque is how torque is calculated. The distance (r) between the pivot point and the force's action point. A vector quantity is a torque. As a vector quantity, torque always has a direction that is perpendicular to the plane that contains the vectors of force and displacement.

Assume that the profit generated by a product is given by where x is the number of units sold. If the profit keeps changing at a

scoray [572]

Answer:

21794.495 units/month

Step-by-step explanation:

Some data are missing which i can assume as per requirement of the Question.

Let us consider that profit generated by a product is given by

p(x) =4√x

Also, consider that the profit keeps changing at a rate of $1000 per month.

Now, Using the chain rule we can write

dp/dx=(dp/dt)÷(dx/dt).

So, we can calculate

dp/dx=2x^(-1/2)=2/√x.

As per question we have to find out dx/dt

Since, dx/dt= (dp/dt)/(dp/dx),

so plugging x=1900 we get 1000√1900/2=21794.495 units/month increase in sales.

7 . Cans of frozen OJ Total Cost ($) 1.25 1 2 2.50 3 3.75 4 5.00

aliina [53]

$\begin{gathered} x=\text{cans of frozen OJ} \\ f(x)=\text{Total cost(\$)} \\ f(x)=1.25x \\ f(1)=1.25(1)=1.25 \\ f(2)=1.25(2)=2.50 \\ f(3)=1.25(3)=3.75 \\ f(4)=1.25(4)=5.00 \end{gathered}$

Independent variable = x(Cans of frozen OJ)

dependent variable = y(total cost)
