Answer:
Therefore the two values required are 2.08 and -11.08.
Step-by-step explanation:
i) f(x) =
+ 10x - 12 is a quadratic equation and a quadratic equation will have two roots whose values when substituted in to the given quadratic equation will give the value.
ii) The question is therefore essentially asking us to find the roots of the given quadratic equation.
This can be done by equating the given quadratic equation to zero and then solving the equation for its roots.
∴
+ 10x -12 = 0 ⇒ x = (-10 ±
) ÷ 2
= (-10 ± 12.166)÷2 = 2.08, -11.08
Therefore the two values required are 2.08 and -11.08
Answer:
Step-by-step explanation?
8 feet 4 inches....12*8= 96, 96+4=100....so your answer is 8 foot 4 inches. because there is 12 inches in a foot, and have 4 left over for the 100.
The interquartile range is 20 you take Q3 in the graph which is 30 and the Q1 in the graph which is 10 then you subtract Q3-Q1 so 30-10 and get 20
Answer:
I believe it's <em>C</em>
Step-by-step explanation:
4 or less let it rest 5 or more go next door I think is how it goes lol
forgot to explain: 6 is more than 5 so we add one to the next place. that makes 2 + 1 which is 3 and 3 is less than 4 so we don't add to the next place.
