Answer: -270

Step-by-step explanation:

First, simplify the exponent

$-6*(25+20)$

Then, distribute

$-150+-120$

Then, subtract(add a negative)

$-270$

Hope it helps <3 :)

-6(-5^2+20)

You’ll first need to evaluate the exponent

-6(-25+20)

Now you need to calculate the additional numbers

-6*-5

30, 30 is your answer. Therefore the value of the expression is 30

How do you divide this as a mixed number. <br> - 2/3 ÷ (- 1/2)

dezoksy [38]

Recipricol the -1/2 to 2 and change the sign to multiply
-2/3 x 2 = -4/3
-4/3 = -1 1/3

-1 1/3 is your answer

hope this helps

Does this graph have any vertical asymptotes? If so, where?

tresset_1 [31]

Answer:

There are no vertical asympotes for this rational function.

Step-by-step explanation:

For rational functions, a vertical asymptote exists for every value of the independent variable such that function become undefined, that is, such that denominator is zero. Let be the following rational function:

$C(p) = \frac{25000\cdot p}{100-p}$ , $0\le p < 100$

There is a vertical asymptote for this case:

$100-p = 0$

$p = 100$

Which is out of the interval given to the rational function. Hence, we conclude that there are no vertical asympotes for this rational function.

Two or zero expresses the possible number of positive real solutions for the given polynomial equation.

Answer: Option D

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

Given equation:

$x^{3}-4 x^{2}-7 x+28=0$

First, we put hit and trial method to find out the one solution. So, if we put x=4 then the above expression will become zero. We can also write the above expression as

$(x-4) \times\left(x^{2}-7\right)=0$
