Prove that there exists a unique real number solution to the equation x3 + x2 − 1 = 0 between x = 2/3 and x=1

ziro4ka [17]

Replace each of the x values given to see if they give 0.

0=(2/3)³+(2/3)²-1
0=(8/27)+(4/9)-1
0≠-0.259

0=(1)³+(1)²-1
0≠1

Therefore, you can see that the solution would have to be between 2/3 and 1.

Hope I helped :)

David is driving on the highway. He begins the trip with 14 gallons of gas in his car. The car uses up one gallon of gas every 2

ehidna [41]

Answer:

$G = -D/20 + 14$

Graph in the image attached.

Step-by-step explanation:

Using the model of a linear equation, we have:

$G = aD + b$

'b' is the y-intercept of the equation, that is, the inicial value of G, when D = 0.

So if David starts the trip with 14 gallons of gas, we have b = 14.

'a' is the slope of the line, that is, an increase of 1 in the value of D causes an increase of 'a' in the value of G.

So if the car uses one gallon every 20 miles, the value of a is -1/20 (an increase of 20 in D causes a decrease of 1 in G).]

So our equation is:

$G = -D/20 + 14$

The graph of this equation is in the image attached.

Dividing whole numbers 22 divided by 300

dezoksy [38]

Answer:

22 divided by 300 will be equal to 0.07333.

Step-by-step explanation:

Dividing 22 by 300

$\frac{22}{300}=\frac{2\times 11}{2\times 2\times 5\times 5\times 3}$

$\frac{22}{300}=\frac{11}{2\times 5\times 5\times 3}=\frac{11}{150}$

$\frac{11}{150}=\frac{11}{15}\times \frac{1}{10}$

The value of $\frac{11}{15}=0.7333$

$\frac{22}{300}=\frac{11}{150}=0.7333\times \frac{1}{10}=0.07333$

So, the value of 22 divided by 300 will be equal to 0.07333.
