If the zeros of a quadratic function, F, are -2 and 4, what is the equation of the axis of symmetry of F
vagabundo [1.1K]

Answer:

x=1

Step-by-step explanation:

if the zeroes are (-2,0) and (4,0), then the axis of symetry is going to be right in the middle of those two, with the graph reflected equally on either side.

so you get:

(4-2)÷2=1

therefore the equation of the axis of symetry is x=1

Given

Base\ Area = 7yd * 2yd

Height = 14yd

Required

The volume

The volume is given as:

Volume = Base\ Area * Height

Where:

Base\ Area = 7yd * 2yd

Height = 14yd

So, the equation becomes

Volume = 7yd * 2yd * 14yd

Express in simplest radical form.<br> V40
Andrews [41]

Answer:

\huge\boxed{2 \sqrt{10}}

Step-by-step explanation:

When taking a square root and making it a radical, we need to list out it's factors and find which one we can take the square root of.

The factors of 40 are:

1, 2, 4, 5, 8, 10, 20, 40.

Out of these, we need to look for one that we can find the square root of.

We know that the square root of 4 is 2.

Therefore, we can make \sqrt{40} into \sqrt{4 \cdot 10}.

The square root of 4 is 2. Therefore, we can put that outside the radical.

2 \sqrt{10}.

Hope this helped!
