What is the length of BC¯¯¯¯¯ ? Enter your answer in the box. units Triangle A B C with horizontal side B C. Vertex A lies above
OlgaM077 [116]

Answer: The length of BC is 22 units.

Explanation:

It is given that the Triangle ABC with horizontal side BC. Vertex A lies above side BC. Angle B and angle C are marked congruent. The length of side AC is labeled as 2x-24. The length of side AB is labeled as x-2. The length of side B C is labeled as x.

If two angles of a triangle are same it means the triangle is an isosceles triangle.

Since the angle B and C are congruent therefore the lines AB and AC are same.

2x-24=x-2

2x-x=-2+24

x=22

Since the side BC=x therefore the measure of BC is 22 units.

If f(x)=3x5−10x3+5, on what intervals is f″(x)>0?
Ksivusya [100]

Answer:

(0.7937,\infty)

Step-by-step explanation:

we are given an algebraic function in x, such that

f(x) = 3x^5-10x^3+5

To find when second derivative >0

For this let us find first and second derivative by successive differentiation.

f(x) = 3x^5-10x^3+5\\f'(x) =15x^4-30x^2\\f'(x)=60x^3-30

when ii derivative >0 we have

60x^3-30>0

x^3>0.5\\x>0.7937

f"(x)>0 in

(0.7937,\infty)
