Answer:
7
Step-by-step explanation:
So to find the x vertex u have to apply the formula x= -b/2a so it will be
x= -(-4)/2(1)
x= 4/2
x= 2
and to find the y vertex u just substitute the x value into the original equation so it will be
y= (2)^2-4(2)+1
y= 4-8+1
y= -3
so the coordinates of the vertex are (2,-3)
Answer:
So x changes by 10 and the you do 25-6.25
then y/x =1.875x
Using the formula for the Pythagorean theorem a^2 +b^2 = c^2, where a and b are the sides and c is the hypotenuse, we can rplace a and b with the side lengths and solve for c.
7^2 + 3^2 = c^2
49 + 9 = c^2
58 = c^2
c = √58 ( Length of hypotenuse)
If you need it as a decimal: √58 = 7.615773 ( Round answer as needed.)
