Answer:
$1407.15
Step-by-step explanation:
$1,770.00*0.25= $442.5
$1.770-$442.50 = $1327.5
$1327.5*0.06 = $79.65
$1327.50+$79.65 = $1407.15
Answer:

Step-by-step explanation:
I will begin with part two, first.
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius.
Given
x² - 18x + y² - 10y = - 6
Using the method of completing the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(- 9)x + 81 + y² + 2(- 5)y + 25 = - 6 + 81 + 25, that is
(x - 9)² + (y - 5)² = 100 ← in standard form
with centre = (9, 5 ) and r =
= 10
Answer:
20%
Step-by-step explanation:
We can start by finding out how much the price of the television was reduced by.
250 - 200 = 50
Now, we need to know what percent of 250 is 50? Let x represent the percent of 250 that is 50. Using this, we can set up an equation:
<u />
Notice that a percentage can also be written as that number over 100.


Reduce the fraction (250 and 100 have a common factor of 10)

Reduce the fraction again (25 and 10 have a common factor of 5)

Multiply both sides by two

Divide both sides by 5

Therefore the price of the television was reduced by 20%.
Answer:
(x, y) → (kx, ky)
Step-by-step explanation:
The number of rabbits that there will be in 3 years is 14,580.
<h3>What is the number of rabbits in 3 years?</h3>
The growth rates of the rabbits is an exponential growth. The formula that can be used to represent the population of the rabbits in 3 years is:
f(x) = 20(3^x)
Where x represents the number of years. The number of years is 6(3 x 2)
20 x 3^6 = 14,580
