so f ' (x) = 0 and f ' ' (x) = 0 for the same x . so f '(x) = f '' (x) f ' = 4x^3 + 2bx + 8 = f '' (x) = 12x^2 + 2b

Some kangaroos can cover 30 feet in a single jump if a kangaroo counts jump like that 150 times in a row how much farther wound
Svetradugi [14.3K]

Answer:

Distance farther the Kangaroos need to go to cover a mile = 780 feet

Step-by-step explanation:

Given:

Kangaroos cover 30 feet in a single jump.

Kangaroos can make such jumps 150 times in a row.

To find the distance farther it needs to go to cover a mile.

Solution:

Using unitary method to find distance covered by kangaroos in a row.

If in a single jump Kangaroos cover = 30 feet

So, in 150 jumps it will cover = 30\ ft \times 150 = 4500 feet

We know 1 mile = 5280 feet

Thus, distance farther the Kangaroo needs to go to cover a mile will be = 5280\ ft-4500\ ft = 780 feet

BRAINLIEST!!<br> Please at least take a look
Bad White [126]

Answer:

The answer to your question is below

Step-by-step explanation:

1) The triangles are similar by the AA postulate so use proportions to find x.

          x/207 = 170/90

solve for x

          x = 207(170/90)

          x = 207(1.89)

         x = 391 ft

2) These triangles are similar so use proportions to solve it

          x/138 = (x + 60)/207

         207x = 138(x + 60)

         207x = 138x + 8280

          207x - 138x = 8280

                      69x = 8280

                         x = 8280/69

                         x = 120
