You need to break this into smaller shapes. This shape consists of 4 smaller shapes: 3 triangles and 1 rectangle.

Formulas:
Triangle: A = 1/2 bh
Rectangle: A= bh

Let's start with the triangle on top with the points B, C and D.
Base = 6
Height = 3

A = 1/2 (6)(3)
Multiply base by height
A = 1/2 (18)
Multiply.
A= 9

The triangle on the left:
Base= 4
Height = 4

A= 1/2 (4)(4)
A= 1/2 (16)
A= 8

The triangle on the right:
Base= 2
Height= 4

A= 1/2 (2)(4)
A= 1/2 (8)
A= 4

The rectangle in the middle:
Base= 6
Height=4

A= (6)(4)
A= 24

Now add all the areas together:
9 + 8 + 4 + 24 = 45 cm²

Hope this helps! :)

An auto parts chain asked customers to complete a survey rating the chain's customer service as average, above average, or below

Mandarinka [93]

Answer:

The right answer is "0.33".

Step-by-step explanation:

As per the question,

n = 15

Average will be "x = 5"

Now,

The required proportion will be:

⇒ $p=\frac{x}{n}$

By putting the values, we get

⇒ $=\frac{5}{15}$

⇒ $=0.33$

Thus, the above is the appropriate solution.

Graph the functions on the same coordinate axis. {f(x)=−2x+1g(x)=x2−2x−3

NikAS [45]

Answer:

(2,-3) and (-2,5)

Step-by-step explanation:

Let us graph the two equations one by one.

1. $f(x)=-2x+1$

If we compare this equation with the slope intercept form of a line which is given as

$y=mx+c$

we see that m = -1 and c =1

Hence the slope of the line is -2 and the y intercept is 1. Hence one point through which it is passing is (0,1) .

Let us find another point by putting x = 1 and solving it for y

$y=-2(1)+1$

$y=-2+1 = -1$

Let us find another point by putting x = 2 and solving it for y

$y=-2(2)+1$

$y=-4+1 = -3$

Hence the another point will be (2,-3)

Let us find another point by putting x = -2 and solving it for y

$y=-2(-2)+1$

$y=+1 = 5$

Hence the another point will be (-2,5)

Now we have two points (0,1) ,(1,-1) , (2,-3) and (-2,5) we joint them on line to obtain our line

$g(x)=y=x^2-2x-3$

$y=x^2-2x+1-1-3$

$y=(x-1)^2-4$

$(y+4)=(x-1)^2$

It represents the parabola opening upward with vertices (1,-4)

Let us mark few coordinates so that we may graph the parabola.

i) x=0 ; $y=y=(0)^2-2(0)-3=0-0-3=-3$ ; (0,-3)

ii)x=-1 ; $y=(-1)^2-2(-1)-3=1+2-3=0$ ; (-1,0)

iii) x=2 ; $y=(2)^2-2(2)-3 = 4-4-3 =-3$ ;(2,-3)

iii) x=1 ; $y=(1)^2-2(1)-3 = 1-2-3 =-4$ ;(1,-4)

iii) x=-2 ; $y=(-2)^2-2(-2)-3 = 4+4-3 =5$ ;(-2,5)

Now we plot them on coordinate axis and line them to form our parabola

When we plot them we see that we have two coordinates (2,-3) and (-2,5) are common , on which our graphs are intersecting. These coordinates are solution to the two graphs.
