Answer:

x = 61 mph

the average speed on the level Road is 61 mph

Step-by-step explanation:

Let x represent Best's average speed on the level road. (In mph)

Best's average speed on the winding road = x-20

Given;

Total distance travelled = 571 miles

Time travelled on level road = 6 hours

Time travelled on winding road = 5 hours

Distance travelled = average speed × time taken

Total distance travelled can be written as

6 × (x) + 5×(x-20) = 571

6x+5x-100 = 571

11x = 571+100

11x = 671

x = 671/11

x = 61 mph

the average speed on the level Road is 61 mph

Q3) f(x) 2x^2 - 5x, g(x) = 3x^3 find g(4x)
mrs_skeptik [129]

Answer:

g(4x) = 192x^3

Step-by-step explanation:

For this problem, f(x) is irrelevant since we are simply are dealing with g(x).  We will simply replace the value of x in g(x) with 4x.  So let's do that.

g(x) = 3x^3

g(4x) = 3(4x)^3

g(4x) = 3(4^3)(x^3)

g(4x) = 3(64)(x^3)

g(4x) = 192x^3

Hence, g(4x) is 192x^3.

Cheers.

A horse farm is developing a new indoor arena in a rectangular buliding. They want the width of the building to be 3 wide feet a
erastovalidia [21]

Answer:

The area of the building in terms of y in its simplest form is 12(y + 2)

Step-by-step explanation:

Since the area of a rectangle is A = LW where L = length and W = width. From our question, the width of the rectangular building is 3 feet. So, W = 3 feet and its length is 4y + 8  feet. So, L = 4y + 8 feet.

So, the area of the building in terms of y is A = LW

= (4y + 8) × 3

Factorizing out 4 from the expression, we have

= 4(y + 2) × 3

= 12(y + 2)

So, the area of the building in terms of y in its simplest form is 12(y + 2)
