Answer:

p(x - 4) = x³ - 12x² + 48x - 69

Step-by-step explanation:

To evaluate p(x - 4), substitute a = x - 4 into p(a), that is

p(x - 4) = (x - 4)³ - 5

= (x - 4)(x - 4)(x - 4) - 5 ← expand 2nd/ 3rd factors using FOIL

= (x - 4)(x² - 8x + 16) - 5 ← distribute parenthesis

= x³ - 8x² + 16x - 4x² + 32x - 64 - 5 ← collect like terms

= x³ - 12x² + 48x - 69

What is the length of EF in the right triangle below?

Tema [17]

Answer:

Step-by-step explanation:

Since the triangle is right use Pythagoras' identity to find EF

The square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

EF² + DF² = DE² ← substitute values

EF² + 12² = 18², that is

EF² + 144 = 324 ( subtract 144 from both sides )

EF² = 180 ( take the square root of both sides )

EF = $\sqrt{180}$ → A

The sequence an = one third (3)n - 1 is graphed below: coordinate plane showing the points 2, 1; 3, 3; and 4, 9 Find the average

charle [14.2K]

9514 1404 393

Answer:

Step-by-step explanation:

The slope of the line between (3, 3) and (4, 9) is given by the slope formula:

m = <average rate of change> = (y2 -y1)/(x2 -x1)

m = (9 -3)/(4 -3) = 6/1

m = 6

The average rate of change on the interval [3, 4] is 6.
