consider the functions f(x)=3x+30 and g(x)=x^2+20. at what positive integer value of x does the quadratic function, g(x) begin to exceed the linear function f(x)?

Step-by-step explanation:

The duadratic function begin to exceed the linear function when

Solve this inequality:

This inequality is equivalent to

x=5

Step-by-step explanation:

We are given that  

We have to find the positive  integer value of x for which the quadratic function g(x) begin to exceed the linear function f(x).

Interval (

Therefore , g(x) exceed f(x) in the interval (.

g(x) begin to exceed the linear function at x=5

b

step-by-step explanation:

if a was wrong then it has to be b it cant be c either because not all the y intercepts are the same!

ok now , i would like brainlest plz

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
