Explain why the function is discontinuous at the given number a. (select all that apply.) f(x) = x2 − 5x x2 − 25 if x ≠ 5 1 if x = 5 a = 5 lim x→5+ f(x) and lim x→5− f(x) are finite, but are not equal. f(5) is defined and lim x→5 f(x) is finite, but they are not equal. lim x→5 f(x) does not exist. f(5) is undefined. none of the above

no, because the sides are not congruent

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
