Answer:

z = 1/2

Step-by-step explanation:

Step 1: Write equation

22z + 6 - 10 = 6z + 4

Step 2: Solve for z

Combine like terms: 22z - 4 = 6z + 4
Subtract 6z on both sides: 16z - 4 = 4
Add 4 to both sides: 16z = 8
Divide both sides by 16: z = 8/16
Simplify: z = 1/2

Step 3: Check

Plug in z to verify it's a solution.

22(1/2) + 6 - 10 = 6(1/2) + 4

11 - 4 = 3 + 4

Answer: 2285.71

Step-by-step explanation:

Rearranging the simple interest formula, we have P = A / (1 + rt), where P is the Principal, r is the annaul rate and t is the time period.

r = R/100 = 5%/100 = 0.05 per year.

Solving the equation:

P = 3200 / ( 1 + (0.05 × 8)) = 2285.7142857143

Solve the differential equation. (y^2 + xy^2)y' = 1

stira [4]

$(y^2 + xy^2)y' = 1 \ \Rightarrow\ (y^2 + xy^2)\frac{dy}{dx}= 1 \ \Rightarrow\\ \\
y^2(1 + x) \frac{dy}{dx} = 1 \ \Rightarrow\ y^2 dx = \frac{dx}{1 + x}\ \Rightarrow \\ \\
\int y^2 dx =\int \frac{dx}{1 + x} \ \Rightarrow\ \frac{1}{3}y^3 = \ln|1+x| + C\ \Rightarrow \\ \\
y^3 = 3 \ln|1 + x| + 3C\ \Rightarrow\ y = \sqrt[3]{3\ln|1+x| + K},\ \text{where $K = 3C$}
