Answer:
With what part?
Step-by-step explanation:
If planet Y is k times the mean distance from the sun than planet X, the right side of the equation becomes (kA)^3. which is k^3 times the left side, T^2. To equate both sides of the equation, multiply T by k^3/2 so that the left side becomes ((k^3/2) x T)^2 which simplifies into (k^3) x (T^2). Therefore, the answer is k^3/2.
Answer:
r=22.931374,−22.931374
Step-by-step explanation:
Let's solve your equation step-by-step.
1652/3.141593 = 3.141593r^2/3.141593
Step 1: Simplify both sides of the equation.
525.847932=r^2
Step 2: Subtract r^2 from both sides.
525.847932−r^2=r^2−r26
−r^2+525.847932=0
Step 3: Subtract 525.847932 from both sides.
−r^2+525.847932−525.847932=0−525.847932
−r^2=−525.847932
Step 4: Divide both sides by -1.
−r^2/−1 = −525.847932/−1
r^2=525.847932
Step 5: Take square root.
r=±√525.847932
r=22.931374,−22.931374
Answer:
r=22.931374,−22.931374
-2 because the line goes through -2
ANSWER
Find out the how many years can she keep the car.
To proof
As given
Daniela bought a car for $24,000
Each year the value of the car decreases by $1750.
let us assume that the number of years be x.
when daniela sells her car she wants to get at least 10,000 for it.
Than the inequality becomes in the form
24000 - 1750 x ≤ 10000
solve
1750x ≤ 14000
![x \leq \frac{14000}{1750}](https://tex.z-dn.net/?f=x%20%5Cleq%20%5Cfrac%7B14000%7D%7B1750%7D)
x ≤ 8 years
she keeps the cars 8 years .
Hence proved
