Exponential:
 
It is called the exponential function of base a, to that whose generic form is f (x) = a ^ x, being a positive number other than 1.
 Every exponential function of the form f (x) = a^x, complies with the followingProperties:
 1. The function applied to the zero value is always equal to 1: f (0) = a ^ 0  = 1
 2. The exponential function of 1 is always equal to the base: f (1) = a ^ 1  = a.
 3. The exponential function of a sum of values is equal to the product of the application of said function on each value separately.
 f (m + n) = a ^ (m + n) = a ^ m · a ^ n
 = f (m) · f (n).
 4. The exponential function of a subtraction is equal to the quotient of its application to the minuend divided by the application to the subtrahend:
 f (p - q) = a ^ (p - q) = a ^ p / a ^ q
 Logarithm:
 
In the loga (b), a is called the base of the logarithm and b is called an argument, with a and b positive.
 Therefore, the definition of logarithm is:
 loga b = n ---> a ^ n = b (a> 0, b> 0)

Solve for x mathematics
Bas_tet [7]

Answer:

x = 6

Step-by-step explanation:

9 / 6 = (2x - 6) / 4 (by the side splitter theorem)

6(2x - 6) = 36

12x - 36 = 36

12x= 72

x = 6

15 + (5-x)/x=30 solve for x
elixir [45]

Answer:

5/16

Step-by-step explanation:

15+(5-x)/x=30

1) Subtract 15 from both sides:

(5-x)/x=15

2) Multiply both sides by x:

5-x=15x

3) Add x to both sides:

16x=5

4) Divide both sides by 16:

x=5/16

Among 35 students in a class, 20 of them earned A's on the midterm exam, 13 earned A's on the nal exam, and 12 did not earn A's
enyata [817]

Answer:

The correct answer is "\frac{2}{7}".

Step-by-step explanation:

According to the question,

Number of students,

= 35

A ! mid term A,

n(A) = 20

B : final A,

n(B) = 13

Didn't start,

n(A^c \cap B^c) = 12

Now,

⇒ n(A \cup B)=35-12

                   =23

then,

⇒ n(A \cup B)=20+13-23

                   =10

hence,

The probability will be:

⇒ P(A \cap B)=\frac{10}{35}

⇒                 =\frac{2}{7}
