You’re gonna have to use the quadratic formula here and a bit of thinking. We know y is height, and once it touches the ground, it will be 0.
(-b +- sqrt b^2 - 4ac)/2a
2 +- sqrt(4 + 48(400))/-32
(2 +- 138.58)/-32
We don’t want a negative time because it’ll make no sense. So do subtraction
(2-138.58)/-32 = 4.27 seconds aka 4.3 seconds

Step-by-step explanation:
negative three x squared
ANSWER TO QUESTION ONE IS 5
5x2+5=15
5-4=1
15x1=15
QUESTION 2
X = 20
IDK 3 :(
1. "the graph has the same zeros" : so let a be the "triple" root of the cubic polynomial function.
2. So f(x)=

3. Don't forget that the expression might have a coefficient b as well, and still maintain the conditions:

4. Now, f(0)=-5 so




5. the function is

where a can be any real number except 0
Answer:A. 3x^2-2x-1+9x+2x^2-3=5x^2+7x-4
B. 5x^3+4x^2-x-3-5x^2-7x+4=5x^3-x^2-8x+1
C. Polynomials are closed under addition and subtraction...
Step-by-step explanation:
