X+2 =0
x= -2
subs x= -2 in the equation
(-2)^3 - k(-2)^2 +3(-2) +7k = 0
-8 - 4k - 6 +7k =0
3k = 14
k= 14/3
Answer:
Option A.
Step-by-step explanation:
In the given graph there are four intervals in which we have to find the nature of function.
1). In the interval (-∞, -0.7)
f(x) < 0
Because for every value of x, value of the function is negative.
2). In the interval (-0.7, 0.76)
f(x) > 0
For each value of x, value of the function is greater than 0.
3). In the interval (0.76, 2.5)
f(x) < 0
Because in this interval value of the function is negative.
4). Interval (2.5, ∞)
f(x) > 0
Because value of the function for every value of x, is greater than 0.
When we compile all four properties Option A. comes out to be the right option.

An inscribed circle is tangent to
all 3 sides of the triangle it is inscribed in.
The correct option is the second option
Explanation
A circle is inscribed in the triangle if the triangle's three sides are all tangents to a circle. In this situation, the circle is called an inscribed circle, and its center is called the inner center, or incenter.
Since the triangle's three sides are all tangents to the inscribed circle, the distances from the circle's center to the three sides are all equal to the circle's radius
