If u(x)=-2x^2+3 and v(x)=1/x what is the range of (u*v)(x) **the picture should help
nasty-shy [4]
We have that
u(x)=-2 x^{2} +3 \\ \\ v(x)= \frac{1}{x}
u(v(x))=u( \frac{1}{x})=-2( \frac{1}{x} )^{2}  +3 \\ u( \frac{1}{x})= \frac{(3 x^{2} -2)}{ x^{2} }

using a graph tool
see the attached figure

The horizontal asymptote of this function is at <span>y=3</span><span>.
So,
the range of this function is from </span><span>(−∞,3<span>)</span></span>

Samantha’s college runs on a trimester schedule so she receives a bill 3 times a year for tuition. Each trimester costs $1,450,
matrenka [14]

3 times a year for 2 years is equal to 3 x 2, or 6. So we know that she will have to pay her bill 6 times.

The cost for each trimester is $1450, but we still have to add the book costs ($350). So, 1450 + 350 = 1800.

Now we know that she has to pay $1800 six times. So the equation will be:

1800 x 6 = 10800.

It will cost Samantha $10,800 to get her degree.

Cyrus is inviting 11 friends over for pizza. He would like to have enough pizza so each friend can have 1/4 of a pizza. About ho
ExtremeBDS [4]

Answer:

Cyrus needs to order 3 full pizzas to feed his 11 friends .

Step-by-step explanation:

The number of friends invited  = 11

Share of pizza for each friend = 1/4 pizza

Now,  as  1 friend eats 1/4 of  a pizza.

⇒  11 friends eat  = 11 \times \frac{1}{4}  = 2.75

So, 11 friends can eat 2 .75 pizza.

Since pizza come as a whole number.

And 2. 75 is nearly equal to 3.00

Hence,  Cyrus needs to order 3 full pizzas to feed his 11 friends .

In​ 2012, a health insurance plan for a​ 35-year-old and his or her spouse costs ​$301 per month. That rate increased to ​$430 p
katrin2010 [14]

Answer: See explanation

Step-by-step explanation:

Let the cost for insuring the applicant = a.

Let the cost for insuring the spouse = b

Let the cost for insuring the first child= c

Let the cost for insuring the second child = d

A 35-year-old health insurance plan and that of his or her spouse costs ​$301 per month. This means that:

a + b = $301.

That rate increased to ​$430 per month if a child were included. This means the cost of a child will be:

= $430 - $301

= $129

The rate increased to $538 per month if two children were included. This means the cost for the second child will be:

= $538 - $430

= $108

The rate dropped to ​$269 per month for just the applicant and one child. His will be the cost of the applicant and a single child. This can be written as:

a + $129 = $269

a = $269 - $129

a = $140

Since a + b = $301

$140 + b = $301

b = $301 - $140

b = $161

Applicant = $140

The spouse = $161

The first​ child = $129

The second child = $108
