Explain, in words, how you can identify a perfect square trinomial whose leading coefficient is 1
liberstina [14]
When the leading coefficient is 1,
If the constant ( c term) is a perfect square and the b term is 2* the square root of the c term.
Ex.
x*2 + 10x + 25
2*5 = 10 5*5=25
Ex.
x^2 - 12x + 36
2 * -6 = -12 6*6=36

The formula κ​(x)= f′′(x) 1+f′(x)23/2 expresses the curvature of a​ twice-differentiable plane curve as a function of x. Use thi
Katyanochek1 [597]

Answer:

K(x) =  \frac{-10}{[1 + (-10x)^2]^{\frac{3}{2} } }    ( curvature function)

Step-by-step explanation:

considering the Given function

F(x) = -5x^2

first Determine the value of F'(x)

F'(x) = \frac{d(-5x^2)}{dy}

F'(x) = -10x

next we Determine the value of F"(x)

F"(x) = \frac{d(-10x)}{dy}

F" (x) = -10

To find the curvature function we have to insert the values above into the given formula

K(x)  = \frac{|f"(x)|}{[1 +( f'(x)^2)]^{\frac{3}{2} } }

 K(x) =  \frac{-10}{[1 + (-10x)^2]^{\frac{3}{2} } }    ( curvature function)

Which statements can be represented by this equation? Select three options.<br><br> 2n-9.2 =n+4/5
Nookie1986 [14]

Answer:

1, 3, 5

Step-by-step explanation:

Let the number be n

1.Twice a number minus nine and two tenths is the same as the number plus four fifths.

Twice a number is 2n. nine and two tenth = 9.2. Therefore twice a number minus nine and two tenths = 2n - 9.2. the number plus four fifths = n + 4/5

The resulting equation is 2n-9.2 =n+4/5

2.Nine point two decreased by double a number is the same as the number added to four fifths.

Nine point two = 9.2, double a number = 2n. Therefore, Nine point two decreased by double a number is 9.2 - 2n

The resulting equation gives  9.2 - 2n = n + 4/5

3.Nine point two less than twice a number is equal to the number added to four fifths.

Nine point two = 9.2, twice a number = 2n. Therefore Nine point two less than twice a number = 2n - 9.2

The resulting equation is 2n-9.2 =n+4/5

4.Two times the difference of a number and nine and two tenths is equal to the number plus four fifths.

The difference of a number and nine and two tenths is given by n - 9.2. Therefore, Two times the difference of a number and nine and two tenths is 2(n - 9.2).

The resulting equation is 2(n - 9.2) = n + 4/5

5.Double a number decreased by nine and two tenths is the same as the sum of four fifths and the number.

Double a number decreased by nine and two tenths is 2n - 9.2

The resulting equation is 2n-9.2 =n+4/5
