A polynomial p has zeros when I = 0.2 = -

Mathematics

Rainbow [258]3 years ago

Answer:

p(x) = (5x - 1) (x + 3)

Step-by-step explanation:

I apologize if I couldn't answer correctly, the question was a bit hard to understand because of the formatting.

Also I didn't see my answer in the list of answer choices but here it is:

if the polynomial has zeros at 0.2 and -3 the equation would have to be:

p(x)=(x-0.2)(x+3)

This is because plugging either of those numbers into the polynomial would cause it to equal 0.

(x-0.2) can be simplified by multiplying everything in the parenthesis by 5, getting rid of all of the decimals, making the final answer:

p(x) = (5x - 1) (x + 3)

The gas tank of a 2015 Nissan Sentra holds 13.2 gallons. How many pounds of carbon dioxide are produced by burning an entire tan
OLEGan [10]
<span>13.2 gallons=49.9 liters
the gas is the octan C8H18
the combustion of Octan equation is 
C8H18    +   25/2 O2-------------------> 8CO2         +  9 H2O
1mole                                                    8 moles
n(C8H18)=a                                              n(CO2)=b
so 
1 mole/a  = 8moles /b
and b= 8molesx a

we must find the value of a, molar volume of a gas is  v= 22.4l/mol=V/a, so a=V/v= 49.9/22.4= 2.23 moles

and b=8 x a=8x 2.23=17.85 moles
M(CO2)=m(CO2)/n(CO2)====> m=n x M=17.85 * (12+2x16)=  785.4 g

m(CO2)=785.4g = 1.57 pound</span>

Marco has $75 to spend on new clothes for a job interview. He buys a shirt for $18.28, pants for $42.39, and a tie for $12.97. H
dedylja [7]

Answer:

$1.36

Step-by-step explanation:

First, add together the prices of all the clothes:

18.28 + 42.39 + 12.97

= 73.64

Then, subtract this from 75:

75 - 73.64

= 1.36

So, he will have $1.36 left after buying the clothes

A rectangular solid with a square base has a volume of 5832 cubic inches. (Let x represent the length of the sides of the square
Aleks04 [339]

Answer:

a) 18 in x 18 in x 18 in

b) S = 1944\ in2

Step-by-step explanation:

a) Let's call 's' the side of the square base and 'h' the height of the solid.

The surface area is given by the equation:

S = 2s^2 + 4sh

The volume of the solid is given by the equation:

V = s^2h = 5832

From the volume equation, we have that:

h = 5832/s^2

Then, using this value of h in the surface area equation, we have:

S = 2s^2 + 4s(5832/s^2)

S = 2s^2 + 23328/s

To find the side length that gives the minimum surface area, we can find where the derivative of S in relation to s is zero:

dS/ds = 4s - 23328/s^2 = 0

4s = 23328/s^2

4s^3 = 23328

s^3 = 23328/4 = 5832

s = 18\ inches

The height of the solid is:

h = 5832/(18)^2 = 18\ inches

b) The minimum surface area is:

S = 2(18)^2 + 4(18)(18)

S = 1944\ in2
