The answer is m = 7/5 (decimal form is 1.4)
Simplify both sides of the equation and isolate the variable!
The answer would be 3.6
1. first parabola is up, so a are going to be positive
y = a(x-r)(x-s),
roots -7,-3, so we can write y=a(x+7)(x+3) [1]
we can take point (-5,-2), substitute into equation [1], and find value of a
-2=a(-5+7)(-5+3)
-2=a*2*(-2)
a=1/2
so first parabola has an equation
y=1/2(x+7)(x+3)
2. second parabola
y=a(x-r)(x-s) roots are 2 and 4 so we ca write
y=a(x-2)(x-4) take point (3,4) and substitute into this equation
4 =a(3-2)(3-4)
4=-a
a=-4, and it will look down
y=-4(x-2)(x-4)
Answer:
The surface area of the model is 
Step-by-step explanation:
we know that
The surface area of the square pyramid is equal to the area of the square base plus the area of four lateral triangles
so
