tekilochka [14]

Answer:

16/81

Step-by-step explanation:

the probability that they are both even is the probability that the first is even then multiplied by the probability that the second is even:

Formula is:

P(A and B) = P(A) * P(B)

the P(something) is probability of something

so

1 digit: P(even) = 4 possibilities (2,4,6,8) out of 9 total (1,2,3,4,5,6,7,8,9) = 4/9

2 digit:P(even) = 4 possibilities (2,4,6,8) out of 9 total (1,2,3,4,5,6,7,8,9) = 4/9

which is 4/9 * 4/9 =16/81

Find a formula for the inverse of the function f(x)=3x^3 + 2sinx + 4cosx

Explicit Functiony = f(x) is said to define y explicitly as a function of x because the variable y appears alone on one side of the equation and does not appear at all on the other side.

Assign letters to all quantities that vary with time and any others that seem relevant to the problem. Give a definition for each letter.

2. Identify the rates of change that are known and the rate of change that is to be found. Interpret each rate as a derivative.

3. Find an equation that relates the variables whose rates of change were identified in Step 2. To do this, it will often be helpful to draw an appropriately labeled figure that illustrates the relationship.

4. Differentiate both sides of the equation obtained in Step 3 with respect to time to produce a relationship between the known rates of change and the unknown rate of change.

5. After completing Step 4, substitute all known values for the rates of change and the variables, and then solve for the unknown rate of change.</span>Local Linear Approximation formula<span>f(x) ≈ f(x₀) + f'(x₀)(x - x₀)
