Write g(x) = 4x2 + 88x in vertex form. The function written in vertex form is g(x) = (x +11)2 + .
romanna [79]

Answer:

y = 4(x + 11)² - 484

Step-by-step explanation:

y = 4x² + 88x

factor the expression

y = 4(x² + 22x)

complete the square

y + ? = 4(x² + 22x + ?)

y + ? = 4(x² + 22x + 121)

add 4 • 121 to the left side

y + 4 • 121 = 4(x² + 22x + 121)

multiply

y + 484 = 4(x² + 22x + 121)

y + 484 = 4(x + 11)²

subtract both sides by 484

y = 4(x + 11)² - 484

What are the expressions to fin the radius of an object having a circumference of 46 feet
dolphi86 [110]
Since the equation for solving circumference is 2\pir, you can see that 2\pir = 46. Dividing 2\pi on both sides will give you r, or the radius.
Hope this helped! :)

Match each operation involving f(x) and g(x) to its answer.
galben [10]
F(x)=1-x² and g(x)=√(11-4x)

(g+f)(2)=>

 1-(2)²+√(11-4(2))

=√3-3

(f/g)(-1)

(1-(-1)²)/(√(11-4(-1))

=0

(g-f)(-1)

√(11-4*-1)-(1-(-1)²

=√15

(g×f)(2)

1-(2)²×√(11-4(2))
