192 miles divided by 3 hours = 64 miles per hour

448 miles / 64 miles per hour = 7 hours total for the trip

Answer:

Trip will take 7 hours to complete.

Step-by-step explanation:

Kelly drives 192 miles in the first 3 hours.

Speed of Kelly to cover 192 miles = \frac{\text{Distance}}{\text{Time}}

                                                        = \frac{192}{3}

                                                        = 64 miles per hour

Kelly travels with the same speed to cover the whole distance.

Therefore, time taken to cover 448 miles = \frac{\text{Distance}}{\text{Speed}}

= \frac{448}{64}

= 7 hours

Kelly will meet his cousin after 7 hours.

Answer:

m∠3 = 2x - 10° and m∠6 = 3x + 20

m∠3 = 58°          ;    m ∠6 = 122°

Step-by-step explanation:

a ║ b

m∠2 = m∠6                     If ║ cut by a transversal, then corresponding angles

                                         are ≅ and =

m∠7 = m∠3                   If ║ cut by a transversal, then corresponding angles

                                       are ≅ and =

m∠2 = 3x + 20              Given

m∠7 = 2x - 10                 Given    

m∠6 + m∠3 = 180°         If ║ cut by a transversal, then each pair of same-side

                                       interior angles (also called consecutive interior angles

                                       are supplementary (sum = 180°) .    

3x + 20 + 2x - 10 = 180°

5x + 10 = 180°

5x = 170°

x = 34°

Answer:   m∠3 = 2x - 10° and m∠6 = 3x + 20

                m∠3 = 2(34) - 10  ;    m∠6 = 3(34) + 20

                 m∠3 = 58°          ;    m ∠6 = 122°

Determine the total number of roots of each polynomial function.
Kitty [74]
Base on my research there are ways to get the number of roots. If you are looking for negative roots and even the positive one has their own ways. But in this problem, we just need to determine the total number of roots of a polynomial. In determining the total number of roots, you just need to find the degree of the polynomial function. The degree refers to the highest exponent of the polynomial. Therefore, in the function given, 6 is the degree of the polynomial function. The total number of roots is 6.
