Answer:

Step-by-step explanation:

1) False: The function is decreasing (because the base, 1/3, is between 0 and 1).

2) True: The function is decreasing (see #1, above)

3) False: There is no x-intercept.

4) True: If x is 0, then y = (1/3)^0 = 1.

5) False: the range consists of the set of all real numbers greater than zero.

Answer:

$2551\dfrac{1}{2}$

Step-by-step explanation:

$\bf l = 20\dfrac{\sf 1}{4} \ in = \dfrac{81}{4} \ in$

$\bf w = 10\dfrac{1}{2} = \dfrac{21}{2} \ in\\\\\\h = 12 \ in$

Volume of rectangular prism = l*w*h

$= \dfrac{81}{4}*\dfrac{21}{2}*12\\\\\\= 81 *\dfrac{21}{2}*3\\\\\\= \dfrac{5103}{2}\\\\\\= 2551 \dfrac{1}{2} \ cubic \ inches$

A line is perpendicular to y=2/3x+2/3 and intersects the point (-2,4). What is the equation of this perpendicular line?

alexira [117]

Answer:

y = - $\frac{3}{2}$ x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = $\frac{2}{3}$ x + $\frac{2}{3}$ ← is in slope- intercept form

with slope m = $\frac{2}{3}$

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{\frac{2}{3} }$ = - $\frac{3}{2}$

Using the point- slope form

with m = - $\frac{3}{2}$ and (x₁, y₁ ) = (- 2, 4) , then

y - 4 = - $\frac{3}{2}$ (x - (- 2) ) , that is

y - 4 = - $\frac{3}{2}$ (x + 2) ← distribute

y - 4 = - $\frac{3}{2}$ x - 3 ( add 4 to both sides )

y = - $\frac{3}{2}$ x + 1 ← in slope- intercept form
