It is not an equation, it's a function & I guess you have to draw it

h(x) = - 2x/3 - 11/3

It's a linear function: To draw it, try to find 2 points, say A & B.

To find A, plug any (logical) number into x to find y. For instance , let x=0, if so y=-11/3 & the coordinate of the first point A(0, - 11/). Try to find B by following the same methodology

Answer:

(a) 552ft

(b) $220.8

= 2 (12*8+8*9+9*12) = 2 ( 276) = 552 square feet.

(b) Cost of covering the box = $0.40 * 552 feet

viktelen [127]

Answer:

13/28

Step-by-step explanation:

Given

5 red ball
3 blue ball

8 total balls

p(r and r) = 5/8*4/7 = 5/14
p(b and b) = 3/8*2/7= 3/28

Added up

5/14 + 3/28 = 10/28 + 3/28 = 13/28

Probability of 2 same colored balls is 13/28

What is the area of the figure to the nearest tenth?

pantera1 [17]

Area of a sector (s) = radius (r) · θ (in radians)

First, convert 168° into radians using the proportion π = 180°
$\frac{ \pi}{180} = \frac{x}{168}$
$\frac{168\pi }{180} = x$
$\frac{14 \pi }{15} = x$

Next, plug in x for θ
s = r · θ
   = 8 · $\frac{14 \pi }{15}$
   = $\frac{112 \pi }{15}$
   = 23.457
   ≈ 24.0
