What is the length of the third side of the window frame below? (Figure is not drawn to scale.)

Answers

You can solve this using the Pythagorean theorem which states that the square of the length of the hypotenuse is the sum of the square of the lengths of the two legs. In equation form:
c2 = a2 + b2
If the third side is b,
b2 = c2 - a2
b = sqrt(c2 - a2)

Using the given values:
b = sqrt (65^2 - 60^2)
b = 25 in

2x^2 + 108 = 42x NEED HELP SOLVING QUADRATIC EQUATION

Answers

Answer:

x = 18

x = 3

Step-by-step explanation:

2x² - 42x + 108 = 0

common factor is two, so take it out to simplify equation

2 (x² - 21x + 54) = 0

0/2 = 0

x² - 21x + 54 = 0

Factors of 54 which add up to 21 is 18 and 3

(x - 18)(x - 3) = 0

Hence,

x = 18

x = 3

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

Answer:

See below

Step-by-step explanation:

● (7x^3 - 2x^2 -12) + (-3x^3 - 8x^2 +10x)

● 7x^3 - 2x^2 - 12- 3x^3 - 8x^2 + 10x

Combine like terms

● 7x^3 - 3x^3 -2x^2 - 8x^2 -12 + 10x

● 4x^3 - 10x^3 +10x -12
