Answer:

Time t = 3.02 hours

Step-by-step explanation:

Given;

Distance d = 350 km

Speed v = 72 mi/h

Since 1 mile ≈ 1.61 km

Converting the speed to km/h

Speed v = 72 mi/h × 1.61km /mi

Speed v = 115.92 km/h

Speed = distance/time

Time t = distance/speed = d/v

Substituting the values;

Time t = 350 km/115.92 km/h

Time t = 3.019 hours

Time t = 3.02 hours (to the nearest hundredth.)

Find an equation of a line containing the point (-6,3) and has slope<br> - 1/3
AfilCa [17]

Answer: y=-1/3x+1

Step-by-step explanation:

To find an equation that contains the given point and has the same slope, we can plug it into slope-intercept form to find the y-intercept.

3=-1/3(-6)+b         [multiply]

3=2+b                   [subtract both sides by 2]

b=1

Now that we know the y-intercept, we know that the equation is y=-1/3x+1.

Write the product in simplest form: 3w^4 * (-5w^2)
Grace [21]

3w^{4} (-5w^{2} ) = -15w^{6}

I think this is what you want? When multiplying with exponents, you either add or multiply the exponents.

When you multiply the exponent:

(x²)³ = x^{6}

(3x^{4} )^{2} = 9x^{8}

When you add the exponents:

(x²)(x³) = x^{5}

(x²)(x²) = x^{4}

(x^{4} )(x^{3} ) = x^{7}

Organize the following polynomial expressions from least to greatest based on their degree: x 2xyz 3x y z 2x3y y2x − 3x 4 9x3yz
bazaltina [42]

Using polynomial concepts, it is found that the sorting of the polynomial expressions from least to greatest based on their degree is given by: I, III, II, IV.

<h3>What is the degree of a polynomial?</h3>

The degree of a polynomial is given by it's largest exponent.

In this problem, the <em>polynomials </em>are given by:

  • I: x + 2xyz.
  • II: 9x³y².
  • III: 18x² + 5ab - 6y
  • IV: 4x^4 + 3x^2 - x - 4

Hence, the respective degrees are: 1, 3, 2, 4, and the ordering from least to greatest is: I, III, II, IV.
