Answer:

∠3=140°

Step-by-step explanation:

∠4 = 40°

∠3 + ∠4 = 180° (co-exterior angles are equal)

∠3 + 40° = 180°

∠3 = 180° - 40°

∠3 = 140°

                                                or^{}          

                                               

∠2 = ∠4 = 40° (corresponding angles)

∠3 + ∠2 = 180° (linear pair)

∠3 + 40° = 180°

∠3 = 180° - 40°

∠3 = 140°

Construct a polynomial function with the stated properties. Reduce all fractions to lowest terms.
drek231 [11]
<h3>Answer:</h3>

g(x) = (11/12)x³ +(11/2)x² +(55/12)x -11

<h3>Step-by-step explanation:</h3>

A polynomial with zero "a" will have (x -a) as a factor. Your 3rd-degree polynomial will have the three factors ...

... f(x) = (x -(-4))·(x -(-3))·(x -1)

This will have a y-intercept of (4·3·(-1)) = -12. In order to move it to -11, we need to vertically scale this function by a factor of 11/12. Then our poynomial is ...

... g(x) = (11/12)(x+4)(x+3)(x-1)

Multiplying this out, you get ...

... g(x) = (11/12)x³ +(11/2)x² +(55/12)x -11

Find the selling price if the cost price is $360 and the gain is 12.5% on cost
mario62 [17]
It is important to note the details already given in the question. Based on those details the answer to the question can be easily determined. Now let us focus on the question given.
Cost price of the product in question = $360
Percentage of gain on the product = 12.5%
Then
amount of gain made on the product = (12.5/100) * 360 dollars
                                                           = 450/10 dollars
                                                           = 45 dollars
So
The selling price of the product in question = (360 + 45) dollars
                                                                     = 405 dollars
