Answer:
All of them are polynomial functions
Step-by-step explanation:
Remember that a polynomial function of x is a function whose value f(x) is always equal to for a fixed n≥0 (the degree of f) and fixed coefficients
For example, is a polynomial function, but
is not because
is not a nonnegative power of x. Another example of a non-polynomial function is
.
f(x)=4⋅11x is polynomial with degree 1 and . For the same reasons, f(x)=3⋅18x and f(x)=10⋅17x are polynomial functions.
f(x)=−4x³−4x²+5x+1 is a polynomial function of degree 3 with . and f(x)=−2x−1 is a polynomial function of degree 1 and coefficients
.
Answer:
7) x= 5, 8) x= 6, 9) x= 7
Step-by-step explanation:
As per the secant theoram, if two secant intersect outside the circle then the product of the exterior secant and total length of each secant are equal.
7) ∴
opening parethesis and distributing 3 with x and 3.
⇒
subtracting 9 on both side.
⇒
cross multiplying
∴ x= 5.
8)
Opening parethesis and distributing 4 with x and 4.
⇒
⇒
subtracting 16 on both side.
⇒
cross multiplying
∴ x= 6.
9)
opening parethesis and distributing 5 with x and 5.
⇒
subtracting 25 on both side.
⇒
cross multiplying
∴ x= 7.
