Answer:

by definition, an exponential function with base c is defined by h (x) = ac^x  

where a ≠0, c > 0 , b ≠1, and x is any real number.

The base, c, is a constant and the exponent, x, is a variable.  

so if we have  f(x)=3(3\8)^2x, this equivalent to f(x)=3(3\8)^y(x),  

where y (x)=2x,  

therefore, the base is  3/8, and the variable is the function y (x)=2x,  it is 4

Step-by-step explanation:

Answer:

X + Y could equal to [tex]1 \frac{2}{5}X[/tex] or [tex]3 \frac{1}{2}Y[/tex].

Step-by-step explanation:

2X = 5Y

Y = [tex]\frac{2}{5}X[/tex]

X = [tex]\frac{5}{2}Y[/tex]

Hence, X + Y could equal to X + [tex]\frac{2}{5}X[/tex] = [tex]1 \frac{2}{5}X[/tex] or Y + [tex]\frac{5}{2}Y[/tex] = [tex]3 \frac{1}{2}Y[/tex].

Hence, X + Y could equal to [tex]1 \frac{2}{5}X[/tex] or [tex]3 \frac{1}{2}Y[/tex].

Answer: B (-2)

Step-by-step explanation:

[log base b of a = c] turns into [b^c = a]

You have log base 5 of 1/25 = ?, so it turns into 5^? = 1/25

This part is sort of guess and check, but we can look at it to find the answer pretty easily. First, it's 1/n, so we should use a negative power: 5^-1 = 1/5

In addition to being in the denominator, it's 25, which is 5^2.

So, if we want to put it in a reciprocal as well as square it, we can use -2:

5^(-2) = 1/(5^2) = 1/25

Since -2 (B) is the exponent we place on 5 to get 1/25, it is also the answer to log base 5 of 1/25.

The value of log5 (1/25) is -2.

To evaluate the expression log5 (1/25), we need to determine the exponent to which we must raise 5 to get 1/25.

In other words, we need to find the value of x in the equation 5ˣ = 1/25.

We can rewrite 1/25 as 5⁻², since 5⁻² is equal to 1 divided by 5².

Now, we have the equation 5ˣ = 5⁻².

To find the value of x, we can equate the exponents:

x = -2.

Therefore, the value of log5 (1/25) is -2.

Option B) -2 is the correct answer.

The logarithm base 5 of 1/25 is -2 because -2 is the exponent to which we must raise 5 to obtain 1/25. In general, the logarithm function provides the exponent needed to produce a specific value as the result of raising the base to that exponent.

The parts of algebraic expression are monimal, polynimial, binomial, trinomial, and multinomial. An algebraic expression represents all the possible values of variable it consist.

Algebraic Expression- Algebraic expression is the combination of variables, coefficient, constant or all three in a mathematical form  where both side set equal to each other.

Parts of algebraic expression-

The way algebraic expression can express are categorizes in 5 different parts. These are,

        For example  [tex]ax^2[/tex]

         For example  [tex]2b+5c[/tex]

        For example   [tex]5X^2-10y^2[/tex]

        For example   [tex]ax^2+by^3-xy^2[/tex]

        For example [tex]a^2+b+c^3+d[/tex]

An algebraic expression represents all the possible values of variable it consist. We use algebraic equation when we do not know the value of variable or unknown things. To find out the values of these variables the algebraic expression are useful.

Hence the parts of algebraic expression are monimal, polynimial, binomial, trinomial, and multinomial. An algebraic expression represents all the possible values of variable it consist.

Standard deviation of given data = 3.16227

Step-by-step explanation:

Step(i):-

Given sample size 'n' = 5

Given data  4, 6,8,10,12

[tex]Mean = \frac{4+6+8+10+12}{5} = 8[/tex]

Mean of the sample x⁻ = 8

Standard deviation of the sample

Answer:

88 adult tickets and 77 student tickets were sold.

Step-by-step explanation:

Let the number of adult tickets sold be 8x and the number of student tickets sold be 7x.

adult tickets + student tickets = 165 tickets

8x + 7x = 165

15x = 165

x = 165 ÷ 15

  = 11

No. of adult tickets sold (8x) = 11 × 8

                                               = 88

No. of student tickets sold (7x) = 11 × 7

                                                   = 77

88 adult tickets were sold and 77 student tickets were sold.

Two or more expressions with an Equal sign is called as Equation.

Given,

A theater sells adult tickets and student tickets.

Let us consider number of adult tickets sold be 8x and the number of student tickets sold be 7x.

8x + 7x = 165

15x = 165

Divide both sides by 15

x = 165/15

= 11

No. of adult tickets sold (8x) = 11 × 8= 88

No. of student tickets sold (7x) = 11 × 7= 77

Hence, 88 adult tickets were sold and 77 student tickets were sold.
