A = 6

tn = a + (n - 1)d

t4 = 6 + 3d = 12

3d = 12 - 6 = 6

d = 6/3 = 2

f(n + 1) = f(n) + 2

tn = a + (n - 1)d

t4 = 6 + 3d = 12

3d = 12 - 6 = 6

d = 6/3 = 2

f(n + 1) = f(n) + 2

**Answer:**

The graph of the circle and function g(x) intersects at the positive and negative x-coordinates as well as at the origin.

**Step-by-step explanation:**

The equation of circle is given as:

also the graph of the function g(x) is given by:

We are given a set of values in a table as:

x g(x)

−4 −4

−2 −2

2 2

Hence, the function g(x) could be computed with the help of slope intercept form of a equation as:

y=mx+c; where m denotes the slope of the line and c denotes the y intercept.

when x=-4 g(x)=y=-4

-4=-4m+c

also when x=-2 then y=g(x)=-2

-2=-2m+c

on solving the above two equations using elimination method we get,

m=1 and c=0

hence, y=g(x)=x

Now we are asked tgo find whether the graph of the circle and g(x) intersect each other or not.

**Clearly from the graph we could see that the graph of the circle and function g(x) intersects at the positive and negative x-coordinates as well as at the origin.**

**Answer: The length of the median from angle B is 8 units.**

**Step-by-step explanation: **As shown in the attached figure, A(-6, 7), B(4, -1) and C(-2, -9) are the vertices of ΔABC.

We are to find the **length of the median BD from angle B to side AC.**

Since BD is the median on side AC. **So, D will be the mid-point of side AC.**

**Therefore, the co-ordinates of the point 'D' are**

**Now, the length of median BD is equal to the distance between the vertex 'B' and the point 'D'.**

**Therefore, the length of median BD calculated using distance formula is**

**Thus, the length of the median from angle B is 8 units.**

4x^2-8x=8x-8x

4x^2-8x=0

4x(x-2)=0

x=0 or x=2

Therefore x=2

4x^2-8x=0

4x(x-2)=0

x=0 or x=2

We have two unknowns from the equation therefore, two equations are needed. These equations are:

3x + y = 9

y = –4x +10

To solve for y, we first substitute the second equation to the first one.

3x + –4x +10= 9

x = 1

We substitute the value of x to either of the equations and solve for y.

y = –4(1) +10

**y = 6**
