Answer:
-35
Step-by-step explanation:
:D
The given equation is
We need to determine the type of solution and the number of solutions.
<u>Solving the equation:</u>
Let us solve the equation to determine the number of solution and the type of solution.
Subtracting both sides of the equation by 16c, we get;
Adding both sides of the equation by 32, we have;
Let us solve the equation using the quadratic formula.
Thus, we have;
Simplifying, we get;
Thus, the solution of the equation is 4.
Hence, the equation has one rational solution.
Therefore, Option A is the correct answer.
Answer:
Step-by-step explanation:
The discriminant is what's under the square root sign in the quadratic equation. The equation for the discriminant is , where b is the coefficient of x, a is the coefficient of , and c is the number with no variable attatched to it. If we plug in the numbers () it gives you 241, which is the discriminant. Since 241 is more than zero, it has 2 zeros. If the discriminant was 0, there'd be 1 zero, and less then zero there would be zero zeros.
Answer:
The velocity is the speed in a given direction hence the units are the same as that of speed, m/s. Thus the answer is 30 m/s.
Step-by-step explanation:
I do not understand the second option.
You just put the answers into the equation so a) 10x1.1 + 5 = 16
7.5x1.1 + 25 = 33.25
b) 10x1.7 + 5 = 22
7.5x1.7 +25 = 37. 75
c) 10x8 + 5 = 85
7.5x8 + 25 = 85
In c ^ they both have the same amount of money (85) so the answer is c
