Find the value of c that makes each trinomial a perfect square<br> x^2-19x+c<br> Please Help! :)
tensa zangetsu [6.8K]

The value of c is \frac{361}{4}

Explanation:

Given that the trinomial is x^2-19x+c

We need to determine the value of c such that the trinomial is a perfect square.

The value of c can be determined using the formula,

c=(\frac{b}{2})^2

From the trinomial, the value of b is given by

b=-19

Substituting the value of b in the above formula, we have,

c=(\frac{-19}{2} )^2

Squaring both the numerator and denominator, we have,

c=\frac{361}{4}

Thus, the value of c is \frac{361}{4} which makes the trinomial a perfect square.

Factor out the GCF from the given polynomial. 10^3 + 16^2 - 18x 10^3 + 16^2 - 18x = (Type your answer in factored form.)​
Vesna [10]

Correct question is;

Factor out the GCF from the given polynomial. 10x³ + 16x² - 18x. (Type your answer in factored form.)​

Answer:

GCF = 5x² + 8x - 9

Step-by-step explanation:

The given polynomial is;

10x³ + 16x² - 18x

First thing is to inspect the coefficients and see the greatest number that all three can be divided by evenly without remainder.

The greatest number is 2.

Secondly let's inspect the variables to see what we can factor out.

They all contain x. Thus, x is a factor.

Thus, we will divide each term by 2x to obtain the GCF of the polynomial.

GCF = (10x³/2x) + (16x²/2x) - (18x/2x)

GCF = 5x² + 8x - 9

In a parallel circuit, ET = 120 V, R = 470 Ω, and XL = 500 Ω. What is the reactive power?
ddd [48]

Answer:

Reactive power is 28.8VARs

Step-by-step explanation:

We are given that in a parallel circuit, E_{T}=120V,R=470Ω and X_{L}=500Ω

And we area asked to find reactive power.

Reactive power is power dissipated due to reactive elements in the circuit and it occurs when voltage and current are not in phase.

Reactive power = \frac{E_{T}^{2}}{X_{L}}=\frac{120^{2}}{500}=28.8VARs
