Answer:

C

Step-by-step explanation:

not enough information to prove they are congruent. the postulates need 3 things that are congruent, unless it's a right triangle, you only need two. However, in this image, they are not shown to be right triangles.

Sin (3x) dx = ?<br> find the integral
AVprozaik [17]

Answer:

\displaystyle \displaystyle \int {sin(3x)} \, dx = \frac{-cos(3x)}{3} + C

General Formulas and Concepts:

<u>Calculus</u>

Antiderivatives - Integrals

Integration Constant C

Integration Property [Multiplied Constant]: \displaystyle \int {cf(x)} \, dx = c \int {f(x)} \, dx

Trig Integration: \displaystyle \int{sin(x)} \, dx = -cos(x) + C

U-Substitution

Step-by-step explanation:

<u>Step 1: Define</u>

\displaystyle \int {sin(3x)} \, dx

<u>Step 2: Identify Substitution Variables</u>

u = 3x

du = 3dx

<u>Step 3: Integrate</u>

  1. [Integral] Rewrite:                                                                                           \displaystyle \frac{1}{3}\int {3sin(3x)} \, dx
  2. [Integral] U-Substitution:                                                                                \displaystyle \frac{1}{3}\int {sin(u)} \, du
  3. [Integral] Trig Integration:                                                                              \displaystyle \frac{1}{3}[-cos(u)] + C
  4. [Expression] Multiply:                                                                                     \displaystyle \frac{-cos(u)}{3} + C
  5. [Expression] Back-Substitute:                                                                        \displaystyle \frac{-cos(3x)}{3} + C

Suppose the weather forecast calls for a 60% chance of rain each day for the next 3 days. What is the probability that it will N
erastovalidia [21]

Answer:

Probability that it'll not rain during the next three days = 0.064

Step-by-step explanation:

Given

Let:

P(R) represent the probability that it'll rain each day

P(R') represent the probability that it'll not

P(R) = 60\%

Required

Probability that it'll not rain during the next three days

From concept of probability;

P(R) + P(R') = 1

Substitute 60% for P(R)

60\% + P(R') = 1

Subtract 60% from both sides

60\% - 60\% + P(R') = 1 - 60\%

P(R') = 1 - 60\%

Convert % to decimal

P(R') = 1 - 0.6

P(R') = 0.4

The probability that it'll not rain during the next 3 days is:

P(R') * P(R') * P(R')

P(R') * P(R') * P(R') =0.4 * 0.4 * 0.4

P(R') * P(R') * P(R') = 0.064
