Answer:

${ \underline{ \sf{\int\limits^2_1 {x^{2}-8x+8 } \, dx} \: = \: - 1}}$

Step-by-step explanation:

${ \tt{\int\limits^2_1 {x^{2}-8x+8 } \, dx}} \\ \\ = { \tt{[ \frac{ {x}^{3} }{3} - 4 {x}^{2} + 8x ] {}^{2} _{1}}}$

Substitute x with the limits:

$= { \tt{( \frac{ {2}^{3} }{3} - 4( {2)}^{2} + 8(2)) - ( \frac{ {1}^{3} }{3} - 4( {1)}^{2} + 8(1)) }} \\ = { \tt{( \frac{8}{3} - \frac{11}{3} )}} \\ \\ = { \tt{ - 1}}$

A mountain climber started at sea level and descended down a cliff. Her location can be represented by -75 feet. How many feet d

mariarad [96]

The mountain climber has travelled 75 feet below sea level while descending down a cliff.

Given:

A mountain climber at sea level starts descending down a cliff.
Her location can be represented by -75 ft.

To find:

The distance travelled by a mountain climber.

Solution

Distance ascending above sea level is taken in a positive direction.
Distance descending down sea level is taken in a negative direction.
This negative and positive only represents the direction

The location of mountain climber after descending from cliff = -75 ft

The distance covered by the mountain climber = 75 ft

The mountain climber has travelled 75 feet below sea level while descending down a cliff.

Which is a zero of the quadratic function f(x) = 16x?? + 32x - 9?

STALIN [3.7K]

Answer:

f(x) = 16x2 + 32x - 9

To find the "zeros", set f(x) = 0:

0 = 16x2 + 32x - 9

The equation is solvable by factoring or by using the quadratic formula. The factors (use the "ac" method) are:

0 = (4x-1)(4x+9)

x = 1/4 = 0.25 and x = -9/4 = -2.25
