Answer:
-7 and -25
A and C are correct
Step-by-step explanation:
The graph of a certain quadratic function has no x-intercepts.
As we know if graph has no x-intercept then complete graph either above x-axis or below x-axis.
The zeros of this quadratic function are imaginary.
Discriminant = D
D must be negative for imaginary zeros.
In the given options A=-7 and C=-25 are negative.
Hence, -7 and -25 are discriminant which has no x-intercept.
Answer:
B
Step-by-step explanation:
The rational number is the number which can be written as where q is natural and p is integer.
Theorem: If m is a rational number, which can be represented as the ratio of two integers i.e. and the prime factorization of q takes the form , where x and y are non-negative integers then, it can be said that m has a decimal expansion which is terminating.
Theorem: If m is a rational number, which can be represented as the ratio of two integers i.e. and the prime factorization of q does not take the form , where x and y are non-negative integers. Then, it can be said that m has a decimal expansion which is non-terminating repeating (recurring).
The fraction is a rational number, because 1 is integer and 11 ia natural. So, options A and D are false.
Since we cannot represent 11 as a product , then is a rational number that has a repeating decimal expansion. Option B is true.
B) Function, an I put has 2 different outputs
Answer:
Option C
Step-by-step explanation:
By applying cosine rule in the given triangle,
BC² = AB² + AC² - 2(AB)(AC)cosA
(11)² = 8² + 7² - 2(8)(7)cosx
121 = 64 + 49 - 112cos(x)
cos(x) = -
x =
x = 94.1°
Therefore, Option C will be the correct option.
