1. You con solve the quadratic equation x^2+20x+100=50<span> by following the proccedure below:
2. Pass the number 50 from the right member to the left member. Then you obtain:
x^2+20x+100-50=0
</span><span> x^2+20x+50=0
</span><span>
3. Then, you must apply the quadratic equation, which is:
x=(-b±√(b^2-4ac))/2a
</span><span>x^2+20x+50=0
</span><span>
a=1
b=20
c=50
4. Therefore, when you simplify, the result is:
-10</span><span>±5</span>√2 (It is the last option).<span>
</span>
Answer:
Step-by-step explanation:
Domain of the function will be,
{x ∈ R | x ≠ -2}
Range of the function is,
{y ∈ R | y ≠ -4}
Intercepts of the function,
Their are no intercepts of the given rational function.
Horizontal asymptotes:
Horizontal line parallel to x-axis representing discontinuity.
y = -4
Vertical asymptotes:
Vertical line parallel to y-axis representing discontinuity.
x = -2
No oblique asymptotes.
Surface area of the pyramid= 4*(area of the triangle) + area of the square
Area of the triangle = (1/2)*base*height=(1/2)*5*5= 25/2 in²
Area of the square = 5*5 =25 in²
Surface area of the pyramid = 4*(25/2) + 25=2*25 + 25=75 in²
