Answer:
Step-by-step explanation:
if these are diagonals ,then
area=(product of diagonals)/2
=(6*14)/2=42 ft²
Answer:
y=-2x^2-4
Step-by-step explanation:
The parabola is wider than it's parent function, y = x^2. Therefore the coefficient, of x^2 (when you refer to quadratic equations it's a) should be greater than 1. Let's take 2.
y = 2x^2
Now it is reflected across the x-axis, so the equation turns to y = -2x^2. The vertex is shifted down 4. Note that it is shifted down, along the y-axis. This makes 'c' (again quadratic equations) -4.
Final Equation: y=-2x^2-4
if u multiply a negative and a negative sign you will get a positive so the answer will be 276
To find the area you do A=bh(basexheight) 12x8=96
