Dr adams measures the daily height of a sunny yellow sunflower, beginning when the sunfliwer is 60 days old. at 60 days, the height is 205 centimeters. after the first 60 days dr. adams finds that the growth rate is 2 centimeters per day. write an expression for the height of d days past 60 days.

Our expression is 205+2d where d is days past 60.

Step-by-step explanation:

Since the sunflower is 205 centimeters at 60 days, every day after 60 will be greater than 205. We will start with 205 in our expression.

205

Now, each day after 60 the sunflower grows 2 centimeters per day. So day 61 will be:

205+2

Day 62 will be:

205 +2+2

Notice, that for two days past 60, the sunflower has grown 2 times as much.

Our expression is 205+2d where d is days past 60.

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.

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
