Answer:

The answer to your question is: g(3) = 34

Step-by-step explanation:

Function                   g(x) = 4(x)² - 3(x) + 7

                                 g(3) = 4(3)² - 3(3) + 7               substitution

                                 g(3) = 4(9) - 3(3) + 7                 simplify

                                 g(3) = 36 - 9 + 7

                                 g(3) = 36 - 2

                                  g(3) = 34

What is the fully factored form of the expression 45x²y2 + 18x3
Llana [10]

Answer:

9x^2(5y^2 + 2x).

Step-by-step explanation:

First find the Greatest Common Factor of the 2 terms.

GCF of 18 and 45 = 9

GCF of x^2 and x^3 = x^2.

The complete GCF is therefore 9x^2.

So, dividing each term by the GCF, we obtain:

9x^2(5y^2 + 2x).

A sequence is defined recursively by the formula f(n+1)=-2f(n). The first term of the sequence is -1.5. Whis is the next term in
podryga [215]
We are told that f(1) = -1.5, and that f(n+1) = -2f(n).
                                                 Then: f(2) = -2f(1) = -2(-1.5) = +3 (answer)

A _[blank 1]_ is a number whose only factors are 1 and itself. If a number has other factors besides 1 and itself, it is called
kykrilka [37]

Numbers whose only factors are 1 and itself is known as prime numbers , numbers whose factors besides 1 and itself are composite numbers, we can use the sieve of Eratosthenes to determine whether the number is prime or composite.

Given a paragraph in which there are blanks:

A _____ is a number whose only factors are 1 and itself. If a number has  factors besides 1 and itself, it is called a _____. You can use divisibility rules or _______ to help you determine whether a number is prime or composite.

We are required to fill the blank with appropriate options.

We have to fill "prime numbers" in the first blank.

We have to fill "composite numbers" in the second blank.

We have to fill "the sieve of Eratosthenes" in the third blank.

Hence numbers whose only factors are 1 and itself is known as prime numbers , numbers whose factors besides 1 and itself are composite numbers, we can use the sieve of Eratosthenes to determine whether the number is prime or composite.
