Answer: 22/3 or 7,(3)

Solution:

h(a)=3a+5

h(a)=27

3a+5=27

3a=27-5

3a=22

a=22/3

a=7,(3)

Hey there!

Okay, so when you get a problem like this, all you need to do in insert the given value into the function and solve.

For example:

As you can see, they state that <em>(a) = 27, </em>so you insert 27 in for a in the function and it will look like this:

h(27) = 3(27) + 5

Now you solve on the right side of the equal sign:

3(27) = 81 (you multiply them)

81 + 5 = 86

When you plug the value of 27 in for a in this function, your output is equal to 86.

Classify the polynomials by its degree and the number of terms.

Answer:

1.) 7th degree trinomial

2.) 5th degree binomial

Step-by-step explanation:

The degree of a term of a polynomial is the sum of the exponents of all the variables of that term. The degree of a polynomial is the same as the term with highest degree. Remember that a plain variable has degree 1. FOr example, 5x is a term of first degree because x is the same as x^1, so its degree is 1.

1.) m^5n^2 +mn^2 + n^6

Look at each term:

m^5n^2: degree = 5 + 2 = 7

mn^2: degree = 1 + 2 = 3

n^6: degree = 6

The highest degree of any term is 7, so the degree of the polynomial is 7.

The polynomial has 3 terms, so it's a trinomial.

Answer: 7th degree trinomial

2.) 12a^3b + 9a^2bc^2

Look at each term:

12a^3b: degree = 3 + 1 = 4

9a^2bc^2: degree = 2 + 1 + 2 = 5

The highest degree of any term is 5,so this is a 5th degree polynomial.

The polynomial has two terms, so it's a binomial.

9k - 6k + 7k - 8 simplify the expression

Kamila [148]

I will gladly simplify it.

9k - 6k + 7k - 8

9k - 6k = 3 k

3k + 7k - 8

3k + 7k= 10k

10k - 8 = 2k

So the simplified form of 9k - 6k + 7k - 8 is 2k

Large Number Calculations

Answer:

19.2 kg

Step-by-step explanation:

Amount of Bananas consumed in US per year = 5.77 million metric tons

Since 1 million = $10^{6}$ and 1 metric ton = 1000 kg, we can write:

Amount of Bananas consumed in US per year = $5.77 \times 10^{6}$ metric tons

Amount of Bananas consumed in US per year = $5.77 \times 10^{6} \times 1000 = 5.77 \times 10^{9}$ kg

Number of people in US = 301 million = $301 \times 10^{6}= 3.01 \times 10^{8}$

We have to find how many kilograms of bananas are consumed per person in 1 year in US. For this we have to divide the total amount of bananas eaten in US per year with total number of people in US, which will be:

$\frac{5.77 \times 10^{9}}{3.01 \times 10^{8}} \\\\ = 19.2$
