Gas prices are projected to increase by 124% by april 2015. a gallon of gas currently costs $3.80. what projected cost of a gallon of gas for april 2015?

$8.51

Step-by-step explanation:

Remember that

we know that

For April 2015 the projected cost of a gallon of gas is equal to multiply the currently cost by the percentage increase

so

The linear equation is equal to

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.
