This  is written in vertex form:-

y = a(x - b)^2 + c   where  (b, c) is the vertex.

Comparing the function in the question to the above:-

b = -2 and c = 0 so the vertex is at the point (-2, 0)  answer

The y intercept occurs when x = 0 so here it is:-

-1.5( 0 + 2)^2 =  -6

y intercept is at ( 0, -6)  answer

Answer:

The vertex = (-2, 0)

The y-intercept of the equation is -6.

Step-by-step explanation:

Since, the vertex form of quadratic equation,

y=a(x-h)^2+k

Where, (h,k) is the vertex of the equation,

Here, the given equation,

y = -1.5(x + 2)^2

\implies y=-1.5(x-(-2))^2+0

By comparing,

The vertex = (-2, 0)

Now, for y-intercept,

x = 0,

y=-1.5(0+2)^2=-1.5(4)=-6

Hence, y-intercept of the equation is -6.

Answer:

8

Step-by-step explanation:

use pythagoras theorem

a^2+b^2=c^2

a^2+6^2=10^2

a^2=10^2-6^2

a^2=100-36

a^2=64

a=square root of 64

a=8

The length would be 16 ft on both sides.. The width would be 7 ft, I think since a wall is forming one side, and he 40 ft, so in order to make the other three side the maximum would be 39 ft, so I think you get it now. This is just my guess... I'm only in sixth grade :/
