If g(x) = 3 - 2x find, g(-1)

pogonyaev

Steps to solve:

g(x) = 3 - 2x when g(-1)

~Substitute

g(-1) = 3 - 2(-1)

~Simplify

g(-1) = 3 - (-2)

~Simplify

g(-1) = 3 + 2

~Add

g(-1) = 5

Best of Luck!

PLEASE HELP HYPERBOLAS What is the length of the transverse axis ?<br> (x-1)^2/25-(y+3)^2/9=1

Sav [38]

Given equation of hyperbola is

$\frac{(x-1)^{2}}{25}-\frac{(y+3)^{2}}{9}=1$

Given hyperbola is the horizontal hyperbola

The standard form of the horizontal hyperbola is

$\frac{(x-h)^{2}}{a^{2}}-\frac{(y-k)^{2}}{b^{2}}=1$

When we compare these two equations, we get

h = 1, a = 5 , k = -3 and b = 3

Length of the transverse axis = 2a

Plug in the value of 'a' as 5

So,Length of the transverse axis = 2(5) = 10

Simplify.<br> -sqrt m^4n^7

Delvig [45]

Answer:

-m^2 |n|^3 sqrt(n)

Step-by-step explanation:

-sqrt( m^4n^7)

We know that sqrt(ab) = sqrt(a) sqrt(b)

-sqrt(m^4) sqrt(n^7)

The sqrt(m^4) = m^2

The sqrt(n^7) = sqrt(n^6) sqrt(n) = |n|^3 sqrt(n) We take the absolute value because if n is negative, n^6 is postive, but n^3 is negative

-sqrt(m^4) sqrt(n^7)

-m^2 |n|^3 sqrt(n)
