<h3>Answer: 0.6 grams per cm</h3>

===================================================

Explanation:

Pick any column and divide the weight over the length

column 1: 9/15 = 0.6

column 2: 12/20 = 0.6

column 3: 18/30 = 0.6

column 4: 30/50 = 0.6

The weight per cm is 0.6 grams per cm

---------

Another way you could look at is like so

9 g = 15 cm

9/15 g = 15/15 cm

0.6 g = 1 cm

We divided both sides by 15 to turn "15 cm" into "1 cm". Think of "per cm" as "per 1 cm". This works for any other column as well.

Answer:

[See Below]

Step-by-step explanation:

___________________________________________________

✦ To figure out the rule of this table you must Add, Subtract, Multiply, and Divide each line to find similarities.

___________________________________________________

✧ Line 1:

$15+9=24$

$15-9=6$

$15*9=135$

$15$ ÷ $9=1.66r$

___________________________________________________

✧ Line 2:

$20+12=32$

$20-12=8$

$20*12=240$

$20$ ÷ $12=1.66r$

___________________________________________________

✧ Line 3:

$30+18=48$

$30-18=12$

$30*18=540$

$30$ ÷ $18=1.66r$

___________________________________________________

✧ Line 4:

$50+30=80$

$50-30=20$

$50*30=1500$

$50$ ÷ $30=1.66r$

___________________________________________________

So with this, we can conclude that each line has a similarity when we did:

$cm$ ÷ $g$

$=1.66r$ (Repeating)

___________________________________________________

So the weight per $cm$ is $1.66$ or $g*1.66r$ .

Answer:

$y=13x+32$

149 engines in 9th year

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

From a look at the photo and the data plot can be represented by the function, so we can pick 2 points in our given graph

(x1, y1) = (2,60)
(x2, y2) = (5,99)

The standard form of a linear equation is:

y = mx + b where:

m is the slope
b is the y-intercept

We know the slope of the function can be found as following:

$m = \frac{y2 - y1}{x2 - x1}$ so in this situation we have:

<=> $m=\frac{99-60}{5-2}=\frac{39}{3}=13$

=> y = 13x + b (1)

Because the line goes through point (2,60) so we substitute it into (1):

60 = 13*2 + b

<=> b = 60 - 26 = 34

=> y = 13x + 34

Now we will substitute x=9 to find the engines produced by company in 9th year as:

$y=13(9)+32\\y=117+32=149$

Hence, the company will produce 149 engines in 9th year

Find the area of the shape shown<br> below.

steposvetlana [31]

Answer:

The area of the figure is 28 units².

Step-by-step explanation:

Find the area of the full rectangle, ignoring the triangle.

$a = lw \\ a = 4 \times 8 = 32$

Then, find the area of the triangle:

$a = \frac{bh}{2} \\ a = \frac{2 \times 4}{2} \\ a = 4$

Finally, subtract:

$32 - 4 = 28$

FinnZ [79.3K]

Answer:

Step-by-step explanation:

Given is a function of x

$f(x) = xe^{-x}$

When y=0 we get x=0 and infinity

Hence x intercept is 0 and one asymptote is x axis.

When x=0 , y =0

$f'(x) = e^{-x}(-x+1)$

$f''(x) = e^{-x}(x-1-1)$

Maxima at x=1, and point of inflection is at x=2

Increasing upto x=1 and then decreases
