50 points will mark brainiest match each exponential function to it's rate of change

Mathematics
1 answer:
nordsb [41]2 years ago
8 0

Step-by-step explanation:

An exponential function of a^x (a>0) is always ln(a)*a^x, as a^x can be rewritten in e^(ln(a)*x). ... The derivative shows, that the rate of change is similiar to the function itself. For 0<a<1, ln(a) becomes negative and so is the rate of change.

In a class of students, the following data table summarizes how many students passed a test and complete the homework due the da
Alexxandr [17]

20 / 27 is the probability that a student chosen randomly from the class passed the test or completed the homework.

<u>Step-by-step explanation:</u>

To find the probability that a student chosen randomly from the class passed the test or complete the homework :

Let us take,

  • Event A ⇒ a student chosen randomly from the class passed the test
  • Event B ⇒ a student chosen randomly from the class complete the homework

We need to find out P (A or B) which is given by the formula,

⇒ P (A or B) = P(A) + P(B) - P(A∪B)

<u>From the given table of data,</u>

  • The total number of students in the class = 27 students.
  • The no.of students passed the test ⇒ 15+3 = 18 students.

P(A) = No.of students passed / Total students in the class

P(A) ⇒ 18 / 27

  • The no.of students completed the homework ⇒ 15+2 = 17 students.

P(B) = No.of students completed the homework / Total students in the class

P(B) ⇒ 17 / 27

  • The no.of students who passes the test and completed the homework = 15 students.

P(A∪B) = No.of students both passes and completes the homework / Total

P(A∪B) ⇒ 15 / 27

Therefore, to find out the P (A or B) :

⇒ P(A) + P(B) - P(A∪B)

⇒ (18 / 27) + (17 / 27) - (15 / 27)

⇒ 20 / 27

∴ The P (A or B) is 20/27.

Help, I don’t know what I’m doing<br> Trigonometry
spin [16.1K]

Answer:

\frac{\sqrt{3} }{6}

Step-by-step explanation:

using the 30- 60- 90 triangle for exact values , then

tan60° = \sqrt{3} , and

cot60° = \frac{1}{tan60} = \frac{1}{\sqrt{3} }

cos60° = \frac{1}{2}

cot60° cos60°

= \frac{1}{\sqrt{3} } × \frac{1}{2}

= \frac{1}{2\sqrt{3} } ← rationalise the denominator by multiplying by \frac{\sqrt{3} }{\sqrt{3} }

= \frac{1}{2\sqrt{3} } × \frac{\sqrt{3} }{\sqrt{3} }

= \frac{\sqrt{3} }{6}
