Well 10 times 80 is 800 and dividing it by 9.8 gives us 81.63
Answer:
<em>The zeros of the polynomial are -1 and 5</em>
Step-by-step explanation:
<u>Quadratic Equation Solving</u>
The standard representation of a quadratic equation is:

where a,b, and c are constants.
Solving with the quadratic formula:

We have the following equation to solve:

Before attempting to solve it, we must simplify the equation.
Collecting like terms and reordering:

Here: a=1, b=-4, c=-5
The discriminant of this quadratic equation is:


Given d is positive, the equation has two roots, and since d is a perfect square, both roots are rational.
Applying the formula:


Dividing by 2:

Separating both roots:
x = 2 + 3 = 5
x = 2 - 3 = -1
The zeros of the polynomial are -1 and 5
I want an answer to this too, I would love some help as well
Answer:
6 < u < 8
Step-by-step explanation:
10 > 5u/4 > 15/2
To solve this, we need to isolate the variable u
10(4) > 5u/4(4) > 15/2(4)
40 > 5u > 30
40/5 > 5u/5 > 30/5
8 > u > 6
It probably wants you to write it in order so,
6 < u < 8
