Answer:
d
Step-by-step explanation:
The values of the x that satisfies the equation 2x² + 7x +3 = 0 is -1/2 and -3 .
<h3>What is a polynomial function?</h3>
A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.
2x² + 7x +3 = 0
2x² + 6x + x + 3 = 0
2x (x+3) + 1(x + 3) = 0
(2x + 1)(x + 3) = 0
2x+ 1 = 0 ; x + 3 = 0
x = -1 / 2 ; x = -3
Thus, the values of the x that satisfies the equation 2x² + 7x +3 = 0 is -1/2 and -3 .

Answer:
0.78125 m
Step-by-step explanation:
First term of this geometric series is 50 m, and the common ratio is 1/2.
Thus, a(n) = (50 m)(1/2)^(n-1)
After the 7th bounce, the ball will reach a height of a(7) = (50 m)(1/2)^(7 - 1), or
a(7) = 50 / (2^6) m = 0.78125 m
