III.
Olenka [21]

Answer:

  • The y-intercept is - 372 and it means that if the manufacturers do not produce and sell any blenders they will have a loss of $ 372.

Explanation:

The polynomial that represents the function is:

  • P(x)=8x+0.3x^2-0.0013x^3-372

Where the variable, x, represents the number of blenders produced and sold monthly, and P(x) is the monthly profit in dollars obtained for the sale of x blenders.

As for the question, the y-intercept is the point on the graph where the function crosses the y-axis, i.e. where the input of the function is x = 0.

Therefore, the y-intercept is the value of the function for x = 0, P(0), and it is found by substituting 0 for x in the polynomial function, which is shown next:

  • P(0)=8(0)+0.3(0)^2-0.0013(0)^3-372=-372

The meaning of this value is that the firm loses $372 when it does not produce and sell any blenders.

Solve each system.<br> y=7-3x<br> 3x+y=10
ad-work [718]

Answer: 0 = 3

Step-by-step explanation: If y = 7 - 3x, we can plug that in for y in the equation 3x + y = 10 by writing it as 3x + 7 - 3x = 10.

                                                                    - 7            - 7

                                                               --------------------------

                                                               3x - 3x        = 3

                                                                       0          = 3

Simplify the expression: sin (2x) cos (5x) − sin (5x) cos (2x).
pantera1 [17]

<u>Given</u>:

The given expression is sin (2x) \ cos (5x) - sin (5x) \ cos (2x)

We need to determine the simplified value of the given expression.

<u>Simplification</u>:

Since, the given expression is in the form of sin a \ cos b-\cos a \ sin b, the given expression can be simplified using the identity \sin (a-b)=\sin a \cos b-\cos a \sin b

Comparing the given expression with the identity, we get;

a=2x and b=5x

Using this in the identity, we get;

sin (2x) \ cos (5x) - sin (5x) \ cos (2x)=sin(2x-5x)

Simplifying, we get;

sin (2x) \ cos (5x) - sin (5x) \ cos (2x)=sin(-3x)

Thus, the simplified value of the given expression is sin (-3x)

Hence, Option c is the correct answer.
