What is the value of polynomial 5x 4x2 3 at x =- 1?

Answers

Answer 1

The value of the polynomial 5x- 4x²+3 at x=-1 is -6 by using the substitution method.

Given that,

The polynomial is 5x- 4x²+3

We have to find the value of the polynomial when x=-1.

We know that,

What is polynomial?

A polynomial is an algebraic expression whose exponents are all whole numbers. There must be non-negative integer variable exponents in all polynomials.

Take the polynomial P(x) = 5x- 4x²+3

P(x) = 5x- 4x²+3

So, we take x=−1,

P(−1)=5×(−1)−4×(−1)²+3

P(−1)=−5−4+3

P(−1)=−6

Therefore, The value of the polynomial 5x- 4x²+3 at x=-1 is -6 by using the substitution method.

The 5th term in a geometric sequence is 120. The 7th term is 30. What are the possible values of the 6th term of the sequence.

Answers

Answer:

± 60

Step-by-step explanation:

aₙ = a₁ * rⁿ⁻¹

a₇ = 30 = a₁ * r⁷⁻¹ = a₁ * r⁶     (1)

a₅ = 120 = a₁ * r⁵⁻¹ = a₁ * r⁴     (2)

(1)/(2): 30/120 = 1/4 = r²

r = ± 1/2   or ± 0.5

a₁ = a₇/r⁶ = 30/0.5⁶ = 1920

a₆ = 1920 * (± 1/2)⁶⁻¹ = 1920 * ± 1/32 = ± 60

The possible values of the 6th term of the sequence ± 60.

The 5th term in a geometric sequence is 120.

The 7th term is 30

We have to determine the 6th term of the sequence.

What is the formula for the nth term of the sequence?

[tex]a_n = a* r^n[/tex]

a₇ = 30 = a₁ * r⁷⁻¹ = a₁ * r⁶  ......   (1)

a₅ = 120 = a₁ * r⁵⁻¹ = a₁ * r⁴   ...  (2)

(1)/(2): 30/120 = 1/4 = r²

r = ± 1/2   or ± 0.5

a₁ = a₇/r⁶ = 30/0.5⁶ = 1920

a₆ = 1920 * (± 1/2)⁶⁻¹ = 1920 * ± 1/32 = ± 60.

Step-by-step explanation:

The measure of angle O is 75 because the angle is always half of the arc, so knowing that, and also cd and abs are congruent, the other side of o is probably the same as the other, so it’d be 75, multiply by 2 and itll be 150.

A coat has an original price of $48.99. Gloria wants to calculate the final cost of the coat including the 7% sales tax. She could use the expression 0.07 (48.99) + 48.99 to determine the final cost. Which other express could she also use to determine the final cost?

(0.07) ($48.99)
(1.07) ($48.99)
(1.93) ($48.99)
(0.93) ($48.99)

Answers

Answer (1.07)(48.99)
Ex
Since the first expression was
(0.07 x 48.99) + 48.99
Then multiply 0.07 by 48.99 =3.4293 + 48.99 = 52.4193

Try

1.(0.07)(48.99) =3.4293

2.(1.07)(48.99)=52.4193

3.(1.93)(48.99)= 94.5507
