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:

2p+6a=$14
3p+9a=$21

3p+9a=21
Subtract 9a
3p=21-9a
divide all by 3
p=7-3a
plug it into start equations

2p+6a=14
2(7-3a)+6a=14
14-6a....+6a=14

this zeroes out...

Kobotan [32]

Answer:

30,40,50

Step-by-step explanation:

If it is a right triangle then the pythagorean theorum would work

a^2+b^2=c^2

30^2+40^2=50^2

900+1600=2500

2500=2500

this means that 30,40,50 is the right answer

*******extra********

also 30,40,50 is a pythagorean triplet

pythagorean triplets form right angles

this one came from the original triplet of 3,4,5---just multiply by 10
