Find the missing coefficients <br><br><br>y=ax^2-10x+c <br>vertex :(-5,20)
Citrus2011 [14]
Remember, for y=ax^2+bx+c the x value of the vertex is \frac{-b}{2a}

so
given
x value of vertex is -5
and
y=ax^2-10x+c
\frac{-b}{2a}=\frac{-(-10)}{2a}=\frac{10}{2a}=
\frac{5}{a}=-5
multiply both sides by a
5=-5a
divvide both sides by -5
-1=a
a=-1


y=-1x^2-10x+c
comlete the square
remember if we do
y=a(x-h)^2+k (h,k) is the vertex
I know, we can subsitute the known values of te vertex
-5 for h and 20 for k then expand

y=-1(x-(-5))^2+20
y=-1(x+5)^2+20
y=-1(x^2+10x+25)+20
y=-1x^2-10x-25+20
y=-1x^2-10x-5

a=-1
c=-5

Kelly has 236 feet of fence to use to enclose a rectangular space for her dog. She wants the width to be 23 feet. Select the cor
Setler [38]

Answer:

Length = x feet = 95 feet

Step-by-step explanation:

The labeled triangles are not included in the question, therefore, I will calculate the length of the rectangular space for Kelly's dog

Perimeter of a rectangle = 2(length + width)

Perimeter of a rectangle = 236 feet

Width = 23 feet

Length = x feet

Perimeter of a rectangle = 2(length + width)

236 = 2(x + 23)

236 = 2x + 46

236 - 46 = 2x

190 = 2x

x = 190/2

x = 95 feet

Length = x feet = 95 feet
