Use the parabola tool to graph the quadratic function f(x)=−12x2+7. Graph the parabola by first plotting its vertex and then plo
Fudgin [204]
First we find the vertex of parabola f(x)=-12 x^{2} +7

The vertex of parabola is ( \frac{-b}{2a},f( \frac{-b}{2a}))
Here,
b = coefficient of x term
a = coefficient of x² term

For given parabola, b = 0 , a = -12

So,
\frac{-b}{2a}= \frac{0}{-24} =0

And,

f( \frac{-b}{2a} )=f(0) = -12(0)+7=7

Thus the vertex of parabola is (0, 7)

To find another point on parabola, substitute x by 1.

f(1)=-12( 1^{2}) +7=-12+7=-5

So the second point on parabola is (1,-5)

The plot of parabola is shown in image below:

Oxana [17]

Answer:

Step-by-step explanation:

6(x+1) = -2(3x+9)

6x+6 = -6x-18

6x+6x+6-6 = -6x+6x-18-6

12x=-24

x= -2

An arrow is shot straight up from a cliff 58.8 meters above the ground with an initial velocity of 49 meters per second. Let up
Papessa [141]

Answer:

s(t)=-9.8t^2+49t+58.8

Step-by-step explanation:

We have been given that an arrow is shot straight up from a cliff 58.8 meters above the ground with an initial velocity of 49 meters per second. Let up be the positive direction. Because gravity is the force pulling the arrow down, the initial acceleration of the arrow is −9.8 meters per second squared.

We know that equation of an object's height t seconds after the launch is in form s(t)=-gt^2+v_0t+h_0, where

g = Force of gravity,

v_0 = Initial velocity,

h_0 = Initial height.

For our given scenario g=-9.8, v_0=49 and h_0=58.8. Upon substituting these values in object's height function, we will get:

s(t)=-9.8t^2+49t+58.8

Therefore, the function for the height of the arrow would be s(t)=-9.8t^2+49t+58.8.
