What is the value of the leading coefficient a, if the polynomial function P(x) = a(x + b)2(x − c) has a multiplicity of 2 at th

kirill115 [55]

If the polynomial function $P(x) = a(x + b)^2(x-c)$ has a multiplicity of 2 at the point (−1, 0) then the factor (x-(-1))=(x+1) twice enters the polynomial representation. So, you have known one part of the left side of the polynomial function that is $P(x) = a(x + 1)^2(x-c)$ .

If polynomial function passes through the point (7,0), then $0 = a(7+ 1)^2(7-c)$ and since $a\neq 0$ you have that c=7.

At last, if polynomial function passes through the point (0,-14), then $-14 = a(0+ 1)^2(0-7)$ and $-14=-7a$ , so a=2.
Answer: a=2.

What is the nth term of 4,9,16,25,36

konstantin123 [22]

Answer:

(n + 1)²

Step-by-step explanation:

note that 4, 9, 16, 25, 36 are square numbers

To generate the terms add 1 to the position n and square, that is

first term : n = 1 → n = 1 + 1 → 2² = 4

second term : n = 2 → n = 2 + 1 → 3² = 9

third term : n = 3 → n = 3 + 1 → 4² = 16

Hence n th term is (n + 1)²

Determine whether the equation below has a one solutions, no solutions, or an infinite number of solutions. Afterwards, determin

Serga [27]

Answer:

One Solution

$x = 8$

Step-by-step explanation:

Given

$-10x = -80$

Required

Determine the number of solution and the value of x

The equation is a linear equation and they have just one solution

Solving further [Divide both sides by -10]

$\frac{-10x}{-10} = \frac{-80}{-10}$

$x = \frac{-80}{-10}$

$x = 8$

Hence;

<em>x has only one value</em>
