-34 -3X= 3 Y =-5X -17 solved in a substitution

During a sale at the electronics store, movies sold for $3 and CDs sold for $2.50. Isla spent $19 and bought a total of 7 movies

Vinvika [58]

She bought 4 Movies and 3 CDs so she spend $19.50 bc 3+3+3+3=12 so 2.50+2.50+2.50=7.50 so 7.50+12=19.50

NO LINKS!!! This is NOT MULTIPLE CHOICE!!!

Answer:

Given equation: $y=(x+1)^2-2$

The function is a quadratic function in vertex form: $y=a(x-h)^2+k$

Translations

For $a > 0$

$f(x+a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units left}$

$f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}$

$f(x)+a \implies f(x) \: \textsf{translated}\:a\:\textsf{units up}$

$f(x)-a \implies f(x) \: \textsf{translated}\:a\:\textsf{units down}$

Parent function: $f(x)=x^2$

Translations

Translated 1 unit left: $f(x+1)=(x+1)^2$

Then translated 2 units down: $f(x)-2=(x+1)^2-2$

Therefore, translate the parent function by 1 unit left and 2 units down to produce the given equation.

A soccer ball is kicked toward the goal. the height of the ball is modeled by the function h(t) = −16t2 48t, where t equals the

mamaluj [8]

It takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground.

<h3>What is the axis of symmetry?</h3>

Axis of symmetry is a line that divides an object into two equal halves, thereby creating a mirror-like reflection of either side of the object.

1. The function is a parabola of the form . The the formula for the axis of symmetry of a parabola is . We can infer from our function that a= -16 and b = 48, so lets replace those values in our formula:

$x = \frac{-b}{2a}$

$x = \frac{(-48)}{-2(16)}$

$x = \frac{-48}{-32}$

x = 1.5

We can conclude that to the left of the line of symmetry the ball is reaching its maximum height, and to the right of the line of symmetry the ball is falling.

2. Lets check how much time the ball takes to reach its maximum height and return to the ground. To do that we are going to set the height equal to zero:

$-16t^{2} +48t = 0$

$-16t(t-3)=0$

t = 0, (t-3) = 0

t = 0, t = 3

From our previous point we know that the ball reaches its maximum time at , which means that it takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground.
