In June, you bought 14.5 gallons of gasoline for $3.18 per gallon. The following February, you bought the same amount of gasolin

e for $1.88 per
gallon. Select the expression(s) that you can use to find how much more you paid in June than in February. Then find this amount
14.5 (3.18 - 1.88)
14.5 x 1.88 - 14.5 x 3.18
14.5 x 3.18 - 14.5 x 1.88
14.5 x 1.88 +14.5 x 3.18

Answer:

14.5 × 3.18 - 14.5 x 1.88

You paid $18.85 more in june than in February

Step-by-step explanation:

In order to find the answer to this question you will need to find how much you paid in June and how much you paid in February.

ex.14.5 x 3.18 - 14.5 x 1.88

To solve this you need to find the product of 14.5 x 3.18 and 14.5 x 1.88 and then subtract them from eachother.

ex.14.5 x 3.18 =46.11

14.5 x 1.88=27.26

46.11-27.26=18.85

Jason jumped off of a cliff into the ocean in Acapulco while vacationing with some friends. His height above ocean measured in f
lbvjy [14]

Answer:

480 feet.

Step-by-step explanation:

We are told that the function h(t)=-16t^2+16t+480 models Jason's height above ocean measured in feet as a function of time and t is the time in seconds from jumping off.

To find the height of cliff we need to substitute t=0 in our given function as at t=0 we will get Jason's height above ocean which is same as the height of the cliff.

Upon substituting t=0 in our function we will get,

h(0)=-16(0)^2+16*0+480

h(0)=-0+0+480

h(0)=480

Since, the function gives Jason's height above ocean in feet, therefore, the cliff was 480 feet high.

What is the complete factorization of the polynomial below?<br> x3 + x2 + 9x+9
PIT_PIT [208]

Answer:

(x+1)(x-3i) (x+3i)

Step-by-step explanation:

x^3 + x^2 + 9x+9

We will use factor by grouping

Factor out x^2 from the first group and 9 from the second group

x^3 + x^2      + 9x+9

x^2( x+1)     + 9(x+1)

Factor out (x+1)

(x+1) ((x^2+9)

Now factor x^2+9

x^2 -(3i)^2 = (x-3i) (x+3i)

Replacing this

(x+1)(x-3i) (x+3i)
