16. What is the sum of 8x2 +12 - y2
and x2 - 13+8xy?
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).
What is a quadratic function?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

the price of a calculator is decreased by 21% and now is £207.77. Find the original price
Answer:
£251.40 (rounded to 1 decimal place)Step-by-step explanation:
20% of 207.77 = 41.554
1% of 207.77 = 2.0777
21% of 207.77 = 41.554+2.007=43.6317
207.77+43.6317 = 251.4017

footpath is to be constructed in a park in the shape of a parallelogram. When a coordinate plane is laid over a map of the park, the vertices of the footpath are (−4, 2), (8, 2), (11, 7), and (−1, 7).
Answer:
35.7Step-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

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.

Given that log x = 3 and log y = 5, find log (x^2)(y^2)- log xy
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.
What is a logarithm?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.
