State the vertex and axis of symmetry of the graph of y=ax2+c.
Neporo4naja [7]

State the vertex and axis of symmetry of the graph of y=ax^2+c

General form of quadratic equation is y=ax^2 + bx +c

There is no bx in our given equation, so we put 0x

Given equation can be written as y=ax^2 + 0x +c

a=a , b=0

Now we use formula to find vertex

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

x=\frac{-0}{2a}=0

Now we plug in 0 for 'a' and find out y

y=a(0)^2 + 0x +c= c

So our vertex is (0,c)

The axis of symmetry at x coordinate of vertex

So x=0 is our axis of symmetry

Find the length of WY
DENIUS [597]

Answer:

WY = 180

Step-by-step explanation:

the diagonals of an isosceles trapezoid are congruent , so

ZX = WY , that is

8y - 4 = 7y + 19 ( subtract 7y from both sides )

y - 4 = 19 ( add 4 to both sides )

y = 23

Then

WY = 7y + 19 = 7(23) + 19 = 161 + 19 = 180

47° X Find the unknown angle measure​
Mariana [72]

Answer:

The angle measure is 43 degrees

Step-by-step explanation:

The right angle adds up to 90 degrees in whole, you already have 47 degrees so you want to subtract 47 from 90, then you will get your answer.
