What is the leading coefficient of the polynomial? 7x + 10x2 + 3x3 − 5 A) −5 B) 10 C) 3 D) 7
valkas [14]

Answer:

The answer to your question is: 3, letter C

Step-by-step explanation:

Leading coefficient is the coefficient that is written in front of the variable with the highest power.

                                           7x + 10x² + 3x³ − 5

In this polynomial the term with the highest power is 3, so the coefficient that is in front of the variable with this power is also 3.

Write the first five terms of a sequence. Don't make your sequence too simple. Write both an explicit formula and a recursive fo
Marina CMI [18]

Let the first five terms of a sequence be, 4,8,12,20,24

Ok, let me explain the meaning of term explicit and Recursive formula.

Explicit formula ,is the general formula to find any  term of the sequence.

And, Recursive formula, is the method by which, we can find the nth term of the sequence if (n-1)th term of the sequence is known.

So,the explicit formula for the sequence is,

y = 4 n, where , n is any natural number.

And the recursive formula is .

y = 4 (n-1), with the help of (n-1)th term we can find nth term.

First term =4=4 × 1

Second term =8 =4 × 2

Third term =12=4×3

Fourth term =16 =4 × 4

.....................

...........................

.................................

(n-1) th term =4 × (n-1)

nth term =4 × n

Applying the simple procedure by looking at the first , second and the way the next term goes , the general and recursive formula is obtained.

As, you said you don't want simpler sequence

Consider the first five terms of the sequence, 0, 3,8,15, 24.

Explicit formula =n² + 2 n

Recursive formula=(n-1)²+2(n-1)

If,you will look at the sequence, it is neither Arithmetic nor geometric .

First term =0=0²+0×0

Second term =3=1+2=1²+2 × 1

Third term =8=4+4=2²+2×2

Fourth term =15=9+6=3²+2×3

Fifth term =24=16 +8=4²+2×4

So, Explicit formula= n²+ 2 n, where n is a whole number.

HOPE THIS HELPS!
