Answer:

The required equation is y=-\frac{1}{3}x+2.

Step-by-step explanation:

The equation of line cd is

y=3x-3

Slope intercept form of a line is

y=mx+b

Where, m is slope and b is y-intercept.

Slope of line cd is 3.

The product of slopes of two perpendicular lines is -1.

m_1\times m_2=-1

3\times m_2=-1

m_2=-\frac{1}{3}

Therefore slope of perpendicular line is -\frac{1}{3}.

Point slope form of a line is

y-y_1=m(x-x_1)

Slope of perpendicular line is -\frac{1}{3} and line passing through the point (3,1).

y-1=-\frac{1}{3}(x-3)

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

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

Therefore the required equation is y=-\frac{1}{3}x+2.

Y=3x-3 => slope=m=3
The new line perpendicular has slop = -1/m=-1/3
y=-1/3x+b, b is intercept point (3,1)
=>b=y+1/3x=1+(1/3)3=2
=> y=-1/3x+2

fter production, a computer component is given a quality score of A, B, and C. On the average U of the components were given a q
RoseWind [281]

Answer:

Follows are the solution to this question:

Step-by-step explanation:

In the given question some of the data is missing so, its correct question is defined in the attached file please find it.

Let

A is quality score of A

B is quality score of B

C is quality score of C

\to P[A] =0.55\\\\\to P[B] =0.28\\\\\to P[C] =0.17\\

Let F is a value of the content so, the value is:

\to P[\frac{F}{A}] =0.15\\\\\to P[\frac{F}{B}] =0.12\\\\\to P[\frac{F}{C}] =0.14\\

Now, we calculate the tooling value:

\to p[\frac{C}{F}]

using the baues therom:

\to p[\frac{C}{F}] =  \frac{p[C] \times p[\frac{F}{C} ]}{p[A] \times p[\frac{F}{A}] + p[B] \times p[\frac{F}{B}]+p[C] \times p[\frac{F}{C}] }  

            =  \frac{ 0.17  \times 0.14 }{0.55 \times 0.15 + 0.28 \times 0.12 + 0.17 \times 0.14  } \\\\=  \frac{0.0238}{0.0825 + 0.0336 + 0.0238} \\\\=  \frac{0.0238}{0.1399} \\\\=0.1701

Line t passes through points (10, 1) and (2, 6). Line u is perpendicular to t. What is the slope of line u?
diamong [38]

Let's find the slope for line t first.

We can use the given points 2,6 and 10,1 to find the slope using the slope formula.

\frac{y.2 - y.1}{x.2 - x.1} = m

1 - 6 / 10 - 2

-5/8

The slope is -5/8.

Because we know the slope of this line, we can find the slope of the next line instantly, as they are perpendicular.

When a slope is perpendicular to another, it is equal to the negative reciprocal.

Negative reciprocal of -5/8 = 8/5

<h3>The slope of line u is 8/5</h3>

Answer:

<h2><u><em>46 cm²</em></u></h2>

Step-by-step explanation

the figure is composed of a square with an isosceles right triangle inside, we find the area of ​​the square and we take away the area of ​​the triangle.

Triangle area = lxl, right-angled triangle area side by side divided by two.

  • square area

8 * 8 = 64cm²

  • Triangle area

6 * 6 : 2 = 18 cm²

Area of the shaded region

64 - 18 = 46 cm²

How much fabric is needed to create the lateral faces of the tent?
jek_recluse [69]
Left and right side: 6.4*7=44.8
44.8+44.8=89.6
front (where the zipper is) and back: half of 5*8=20
20+20=40

40+89.6=129.6

the area of the bottom is 7*8=56

the total area is 129.6+56=185.6

I am not sure what lateral area includes. To me, the answer should be 129.6, but 129.6 is not a choice. 
I'd suggest 185.6, the total surface area.
