Discriminant is b^2 - 4ac  

Here its value is 8^2 - 4*1*12 =  64 - 48 = 16

Determine whether the following problem involves a permutation or a combination and explain your answer. How many different ​-le
Alex_Xolod [135]

Answer:

B. The problem involves a combination because the order in which the letters are selected does not matter.

Step-by-step explanation:

Computation technique is a method of statistics to find possible ways of combination. In computation technique it is assumed that order does not matter and letters will be selected at random. Permutation is a statistics technique to find possible ways of combination when the order does matter. Permutation technique cannot be used when order does not matter.

Evaluate the function rule for the given value. y=15*3^x for x = -3
DENIUS [597]

Answer: y=\frac{5}{9}

Step-by-step explanation:

It is important to remember that an Exponential function has the following form:

f(x) =a* b^x

Where  “b”  is b > 0 and b \neq 1 , "a" is a coefficient, "x" is the Independent variable and f(x) is the Dependent variable.

In this case, you have the following Exponential Function given in the exercise:

y=15*3^x

If the value of Dependent variable is -3, then:

x=-3

So, you must substitute that value of "x" into the function:

y=15*3^{(-3)}

And now you must evaluate:

1. According the Negative exponent rule:

a^{-n}=\frac{1}{a^n}

Then:

y=\frac{15}{3^{3}}

2. Simplifying, you get:

y=\frac{15}{27}\\\\y=\frac{5}{9}
