Answer:

9x2-y2 + 8xy -1

Step-by-step explanation:

9x2 -1 - y2 +8xy

9x2-y2 + 8xy -1

The sum of these two given quadratic function is (9x² - y² + 8xy - 1).

A quadratic function is a function that has a variable with the highest power of the variable is 2.

A quadratic function may contain more than one variable. However, the highest degree of any variable must be 2.

Given, two function are 8x² + 12 - y² and x² - 13 + 8xy.

Therefore, the sum of these two given function are:

(8x² + 12 - y²) + (x² - 13 + 8xy)

=  8x² + x² - y² + 8xy +12 - 13

= 9x² - y² + 8xy - 1

Step-by-step explanation:

logx²y² - logxy

= log(x²y²/xy)

= logxy

= logx + logy

= (3) + (5)

= 8.

The value of logx²y² - logxy when log x = 3 and log y = 5 is 8.

The logarithm is the opposite of exponentiation as a function. The exponent to which b must be raised in order to obtain a number x is hence the logarithm of a number x to the base b.

Given:

log x = 3 and log y = 5

logx²y² - logxy

Calculate the above expression as shown below,

logx²y² - logxy = log x²y² / xy

logx²y² - logxy = log xy

logx²y² - logxy = logx + logy

logx²y² - logxy = 3 + 5

logx²y² - logxy =  8

Therefore, the value of logx²y² - logxy when log x = 3 and log y = 5 is 8.

Step-by-step explanation:

1/2 is greater than 1/4 because 1/4 is 1/2 of a 1/2

Hey there! I'm happy to help!

The Greatest Common Factor is self-explanatory: it is the largest factor that both numbers have in common. Let's look at the factors of each of these numbers:

30: 1, 30, 2, 15, 3, 10, 5, 6

45: 1, 45, 3, 15, 5, 9

We see that the largest number they both have in common is 15, so the GCF is 15.

Answer:

Step-by-step explanation:

Step one

Given the coordinates

ABCD with vertices A(−4, 2), B(8,2), C(11, 7), and D(-1, 7).

AB=(−4, 2), (8,2)

BC=(8,2), (11, 7)

CD=(11, 7),(-1, 7)

DA=(-1, 7),(-4,2)

The distance between points AB=

[tex]AB= \sqrt (x_2-x_1)^2+(y_2-y_1)^2[/tex]

[tex]AB= \sqrt (8+4)^2+(2-2)^2\\\\AB= \sqrt 12^2+(0)^2\\\\AB= \sqrt144\\\\AB=12[/tex]

The distance between points BC=

[tex]BC= \sqrt (11-8)^2+(7-2)^2\\\\BC= \sqrt 3^2+(5)^2\\\\BC= \sqrt34\\\\BC=5.8[/tex]

The distance between points CD

[tex]CD= \sqrt (-1-11)^2+(7-7)^2\\\\CD= \sqrt -12^2+(0)^2\\\\CD= \sqrt144\\\\CD=12[/tex]

The distance between points DA

[tex]DA= \sqrt (-4+1)^2+(2-7)^2\\\\DA= \sqrt -3^2+(-5)^2\\\\DA= \sqrt34\\\\DA=5.8[/tex]

Hence the perimeter of the footpath= 12+5.8+12+5.8
