The greater root is -4.
<u>Step-by-step explanation:</u>
- The given equation is
- This a quadratic equation which can be solved using the factorizing method.
- The general form of the quadratic equation is given by
where,
- a is the coefficient of x².
- b is the coefficient of x.
- c is the constant term.
In the given equation, a = 1, b = 10, c = 24.
- Sum of the roots ⇒ b
- Product of the roots ⇒ c
To find the roots of the equation :
- Sum of the roots ⇒ 6+4 = 10 (where b = 10).
- Product of the roots ⇒ 6×4 = 24 (where c = 24).
The solution is given by (x+6)(x+4) = 0.
The roots are given by (x+6) = 0 and (x+4) = 0.
Therefore, x= -6 and x = -4 are the roots of the equation
The greater root is -4.
Percentage error is calculated by
Percentage error = (estimate-real)/real*100%=(115-82.5)/82.5*100%=28.26%
An over-estimate gives a positive error percent, and an underestimate gives a negative error.
Also, dividing by the real value makes it possible to have more than 100% error.
For example, if real cost is $50, and estimated cost is $150, then error percent is (150-50)/50*100%=200%!
A
Step-by-step explanation:
You cant verify the similarity of triangles through their sides, as only angles stay the same, so that eliminates options B and D. Option C is wrong because reflection would be reflecting a figure over someting, say the x-axis. This leaves option A as the only correct choice. Good Luck on the Quiz!
Divide 8/5 by 5/6 and you will get 1 and 23/25 is greater than v
So v is less than
1 23/25
The answer is Option A. Because the rate of change is that the tire loses 3 air pressure every hour, it is a constant, making it a linear relationship.
