Find the difference 9/11-5/12

Answers

Answer 1

Answer: First we need to find a common denominator. For this one, the easiest way to do that is multiply 11 x 12 = 132

now convert the numerator

9x12 = 108
5x11 = 55

108/132 - 55/132 =

now just subtract the numerators

108/132 - 55/132 = 53/132

Answers

divide both sides by 10
x+3=0.9
minus 3
x=2.1

Solutions

Divide both sides by 10

x+3=9 / 10

Subtract 3 from both sides

x=9 / 10 −3

Simplify 9 / 10 −3 to −21 / 10

x=−21 / 10

Answers

Answer:

−3x3−16x2−14x+8

Step-by-step explanation:

first times the first x in parentheses by everything in the second

(x)(-3x^2) and (x)(-4x) and (x)(2)

-3x^3-4x^2+2x

Then times the 4 by the other variables in the parentheses

(4)(-3x^2) and (4)(-4x) and (4)(2)

-12x^2-16x+8

now the whole equation:

-3x^3-4x^2+2x -12x^2-16x+8

now you must simplify or add like terms

-3x^3-16x^2-14x+8 is your answer, which is the first one.

Lim -> 0 sin(2x) /(x*cos(x) )

help

Answers

sin (2x) can be written like:sin (2x) = 2sin(x)cos(x)
substituting this expresion in the original one:sin(2x) /(x*cos(x) =2sin(x)cos(x)/x*cos(x)=2sinx/x
taking limits, and noticing that lim as x->0 of sinx/x=1:lim 2sinx/x=2*1=2x->0

In an area of the Midwest, records were kept on the relationship between the rainfall (in inches) and the yield of wheat (bushels per acre). The data for a 9 year period is given in the table. The equation of the line of best fit for this data is y = 47.3 + 0.78x. How many bushels of wheat per acre can be predicted if it is expected that there will be 17 inches of rain?

Answers

Answer:

Step-by-step explanation:

Given: Data is in terms of rainfall (in inches) and Yield of wheat (bushels

per acre)

Equation of Best fit line for 9 year of data is Y = 47.3 + 0.78X

To find: Bushels of wheat per acre when 17 inches of rain expected.

Given problem is of Regression analysis as we are given with best fit line.

From the Equation of Best fir line we can conclude that it is equation of line Y on X because when put value of X we get value of Y.

From Given Data, let say X be Rainfall length and Y be Yield of wheat.

So, to find the Bushels of wheat (yield) when 17 inches of rainfall is expected.

we put value X = 17 in given equation.

⇒ Y = 47.3 + 0.78 × ( 17 )

⇒ Y = 47.3 + 13.26

⇒ Y = 60.56

Therefore, 60.56 bushels of wheat per acre can be predicted if 17 inches of rain is expected.

Assuming x is the rainfall, you simply plug in 17 for x and solve for y.

47.3 + .78(17)
= 47.3 + 13.26
= 60.56
