Y=3x+2 scope and graphing

Mathematics
1 answer:
DedPeter [7]3 years ago

The general rule for a linear equation is y=mx+c where m is the slope or gradient... therefore the slope is 3.

Now we need to get 2 points on the line.

You can easily get the y-int by substituting x=0 into the equation... therefore the y-int is 11... you have one point on the line: (0,11)

Now that you have one point and we know the gradient or slope which is 3, go from the point you have found (0,11) and go up 3 and across 1 to find a second point... then simply rule a line in between the two points.

For their homecoming​ parade, the students of​ U-Math have created a colorful​ banner, 41 meters in​ length, that is made of two
Rudik [331]

Answer:

33

Step-by-step explanation:

let the shorter piece be x m

then the longer piece is 41-x

"The short piece is 25 meters shorter then the long piece"

or

the difference between the longer and the shorter is 19

--->

(41-x) - x = 25

41-x-x = 25

-2x = 25-41

-2x = -16

divide both sides by -2

x = 8

I defined x to be the short piece ---- 8

I defined 41-x to be the longer --- 41-8 = 33

The volume v of a cylinder is computed using the values 2.2 m for diameter and 6.8 m for height. use the linear approximation to
geniusboy [140]

A linear approximation to the error in volume can be written as

... ∆V = (∂V/∂d)·∆d + (∂V/∂h)·∆h

For V=(π/4)·d²·h, this is

... ∆V = 2·(π/4)·d·h·∆d + (π/4)·d²·∆h

Using ∆d = 0.05d and ∆h = 0.05h, this becomes

... ∆V = (π/4)·d²·h·(2·0.05 + 0.05) = 0.15·V

The nominal volume is

... V = (π/4)·d²·h = (π/4)·(2.2 m)²·(6.8 m) = 25.849 m³

Then the maximum error in volume is

... 0.15V = 0.15·25.849 m³ ≈ 3.877 m³

_____

Essentially, the error percentage is multiplied by the exponent of the associated variable. Then these products are added to get the maximum error percentage.
