The vertex of this parabola is at (2.-3). When the yvalue is -2, the xvalue is 5. What is the coefficient of the squared term in

tatiyna

Answer:

The coefficient of squared term is 1/9

Step-by-step explanation:

The vertex of parabola is (2.-3)

We know the vertex form of a standard parabola

$y=a(x-h)^2+k,\text{ where (h,k) is vertex}$

Plugging values of h and k, h= 2, k = -3

$y=a(x-2)^2-3$

Now, x=5, y=-2

$-2=a(5-2)^2-3$

$-2=9a-3$

$9a=1$

$a=\frac{1}{9}$

Thus, the coefficient of squared term is 1/9

Julli [10]

Angle sum of a triangle = 180°

Therefore:

Equation No. 1 -
2 ( 2x - 4 ) + 5y = 180°
2 ( 2x - 4 ) + 5 [ ( 2x - 4 ) / 5 ] = 180
4x - 8 + [ 5 ( 2x - 4 ) / 5 ] = 180
4x - 8 + 2x - 4 = 180
4x + 2x = 180 + 8 + 4
6x = 192
x = 192 / 6
x = 32°

Equation No. 2 -
5y = 2x - 4
y = ( 2x - 4 ) / 5

ANSWER:
x = 32°

meriva

Simple....

you have: $(3.2* 10^{3} )+(5.78* 10^{5} )$

Simplify....

$(3.2* 10^{3} )=3200$

and

$(5.78* 10^{5} )=578,000$

3,200+578,000=581,200

=581,200

Thus, your answer.
