Speed of Bruce for the rest of the trip is 30 miles/hour.

Step-by-step explanation:

  • Step 1: Total distance = 170 miles. In the trip Bruce's speed = 55 miles/hour. So, in 1 hour, distance covered = 55 miles. Find distance covered in 2 hours and the distance of the last part.

Distance covered in 2 hours = 2 × 55 = 110 miles

Remaining part of the trip = 170 - 110 = 60 miles

  • Step 2: Find the speed of Bruce in the remaining part of the trip when time = 2 hours and distance = 60 miles.

Speed = Distance/Time = 60/2 = 30 miles/hour

Which statement accurately describes how to perform a 90° counterclockwise rotation of point A (−1, −2) around the origin? Creat
Anastaziya [24]

Answer:

last one

Step-by-step explanation:

You are swinging A(-1,-2) around the center which in this case is the origin. Keep in mind that points on a circle all have a equal distance from the origin.  We don't want the distance from the center to change.

We want the center of that circle to be the origin.

So the answer is the last one:

"Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 90° counterclockwise from point A. ​"

Use the long division method to find the result when 6x^3 + 19x2^2 + 17x + 3 is
skelet666 [1.2K]

Answer:

\frac{6x^3 \ + \ 19x^2 \ + \ 17x \ + \ 3}{2x \ + \ 3}  \ = \ 3x^2 \ + \ 5x \ + \ 1

Step-by-step explanation:

Given;

F(x) = 6x³  +  19x²   +   17x   +  3

Factor of F(x) = 2x + 3

Using long division method;

                                   3x²  + 5x  +   1

                                 ------------------------------------

               2x + 3    √  6x³  +  19x²   +   17x   +  3

                             -  (6x³   +   9x²)

                                ----------------------------------------

                                               10x²    +    17x   +  3

                                          -   (10x²     + 15x)

                                             -------------------------------

                                                                  2x   +  3

                                                               - (2x   +  3)

                                                                 ---------------

                                                                         0

Thus, \frac{6x^3 \ + \ 19x^2 \ + \ 17x \ + \ 3}{2x \ + \ 3}  \ = 3x^2 \ + \ 5x \ + \ 1

Answer:

A) 15 cm B) 1292 cm^2

Step-by-step explanation:

A) height can be used by using Pythagoras theorem

Height^2+base^2=slant^2

height^2+8^2=17^2

height=15 cm

B) The amount of cardboard used can be found by calculating the area

Area=2*(area of triangle) + 3*(area of rectangles)

17*16+3*(20*17)=1292 cm^2
