Jasmine purchased a laptop worth $1,500 in 2007. It loses its value by %32 each year. What is the value of the laptop in 2010? R

Lunna [17]

Answer:

$471.65

Step-by-step explanation:

-The value of the laptop after each year is calculated by the formula:

$P_t=P_o(1-d)^t$

where:

$P_t$ is the value at time t

$P_o$ is the initial value

$d$ is the rate of depreciation

$t$ is the time

#We substitute the values to solve for the value after 3 years(2010-2007=3):

$P_t=P_o(1-d)^t\\\\=1500(1-0.32)^3\\\\=\$471.65$

Hence, the value of the laptop in 2010 is $471.65

Which of the following answer choices is an equation for the circle with a center of (-2, 3) and a radius of 3?

mamaluj [8]

Answer:

Step-by-step explanation:

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

Here (h, k) = (- 2, 3) and r = 3 , then

(x + 2)² + (y - 3)² = 9 ← expand left side using FOIL

x² + 4x + 4 + y² - 6y + 9 = 9 ( subtract 9 from both sides )

x² + y² + 4x - 6y + 4 = 0 → A

Your answer to this is:

$\sf{= \frac{1}{2} \: + \frac{2}{1 \: + \: x^2} \: + \: \frac{1}{1 \: + \: x^4} \: + \: \frac{2^1^0^0}{1 \: + \: x^2^0^0}$

<h2>→ <u>EXPLANATION :-</u></h2>

<u /> $\sf{= \frac{1}{2} \: + \frac{2}{1 \: + \: x^2} \: + \: \frac{1}{1 \: + \: x^4} \: + \: \frac{2^1^0^0}{1 \: + \: x^2^0^0} \: (1)$

$\sf{Apply \: rule:} \: (a) = a$

$\sf{(1) = 1$

$\sf{= \frac{1}{2} \: + \frac{2}{1 \: + \: x^2} \: + \: \frac{1}{1 \: + \: x^4} \: + \: \frac{2^1^0^0}{1 \: + \: x^2^0^0} \: ^. \: 1$

$\sf{\frac{1}{1 \: + \:1} = \frac{1}{2}$

$\sf{\frac{2^1^0^0}{1 \: + \: x^2^0^0} ^.^ \: 1 \: = \: \frac{2^1^0^0}{1 \: + \: x^2^0^0}$
