Answer:
Yes it is a polynomial.
It is a trinomial.
The degree is 4.
Step-by-step explanation:
So polynomial is an expression that has variables, constants, and exponents. And all of these are connected through things like addition and subtraction. In this question, you have x as your variable, 0 as your constant, and 4,3,1 as your exponents.
A term is the part of the polynomial that is separated by + or - sign. So in this question, you have 5m^3, -3m^4, and -7m as your terms. Because you have three terms, therefore this is a trinomial.
The degree of polynomial is represented by the variable with the largest exponent, so in your case, 4 is your largest exponent, therefore the degree of the polynomial is 4.
To find a specified term in a geometric sequence, you can use the formula: an = a1r^(n-1), where a1 = first term, n = position number of given term, r = common ratio, and an = value of term in given position.
Since we're only given a4 and r, I'm assuming a1 would be 1 since that would correspond to the rate (If we start off with one, a2 would be 1 * 2 = 2, a3 would be 2 * 2 = 4, and a4 would be 4 * 2 = 8). So now just plug in the numbers for the variables and solve.
a13 = 1(2)^(13-1)
a13 = 1(2)^(12)
a13 = 1(4096)
a13 = 4096
The 13th term of this geometric sequence would be 4096. I hope this answers your question.
3 3/8 × 3 = x
distribute
3×3 + 3×3/8=x
9+9/8=x
9+1+1/8=x
10 1/8=x
Answer:
729/15625
Step-by-step explanation:
1. Evaluate the power
( (27/125) ÷ 1 )^2
2. divide
( 27/125 )^2
evaluate the power
( 27^2 / 125^2 )
729/15625
Hope this helps!!!!!!!!!!!!!!!!!!!
