Answer:

33 - 2x =  {x }^{2}  + 2x + 1 \\  {x}^{2}  + 4x - 32 = 0 \\ x = 8 \\   \\ x = 4

Answer:

x = 4

Step-by-step explanation:

(33-2x)^(1/2) = x + 1

33-2x = x^2 + 2x + 1           [square both sides]

x^2 + 2x + 1 - 33 +2x = 0

x^2 + 4x - 32 = 0

(x - 4)(x + 8) = 0

x = 4

Which equation represents a circle with the same radius as
sattari [20]

Answer :

(x+1)^2+(y-1)^2=4^2 and (x+1)^2+(y-1)^2=16

Step-by-step explanation:

Given : A circle with the same radius as  the circle shown but with a center at (-1.1).

To find : Which equation represents a circle ?

Solution :

The equation of a circle with center (h,k) and radius r is given by :

(x-h)^2+(y-k)^2=r^2

Here, we are given (h,k)=(-1,1)

and radius r=4 units

So, equation of circle will be :

(x-(-1))^2+(y-1)^2=4^2

(x+1)^2+(y-1)^2=4^2

or (x+1)^2+(y-1)^2=16

Therefore, the required equations of circle are

(x+1)^2+(y-1)^2=4^2 and (x+1)^2+(y-1)^2=16

The price of products may increase due to inflation and decrease due to depreciation. Derek is studying the change in the price
iren [92.7K]
Part A.

1) Function given:

f(x)=0.69(1.03)^x

2) Interpretation:

initial value: => x = 0 => f(x) = 0.69

table:

x                f(x)
year          price

0              0.69

1             0.69 * 1.03 = 0.7107 => increase = 3%

2             0.69 * (1.03)^2 = 0.732021 => increase = 3%

So, the answer is that the function is increasing at 3% per year.

Part B.

3) table

<span> t (number of years)      1             2              3                  4
f(t) (price in dollars)     10,100    10,201     10,303.01   10,406.04

Percent change:

Year 2: 10,201 / 10,100 = 1.01 => 1% increase

Year 3: 10,303.01 / 10,201 = 1.01 => 1% increase

Year 4: 10,406.04 / 10,303.01 = 1.01 => 1% increase.

Answer: the </span><span>product of the part A recorded a greater percentage change in price over the previous year (3% vs 1%).</span>
