1a. A regular polygon has 10sides. i)Name the polygon.
ii)How many triangles can be obtained from this polygon if cut into triangles.
iii)Find the sum of its interior angles.
iv)A polygon which has n sides is cut into triangles, write formula to find the sum of its interior angles in terms of n.

b)A student cycles 3km east from A to B and then 4km to C. Find the distance and bearing from C from A. scale: 1cm to 1km. tan60° =1.7.

2a. Find the height h, of the building if the scale is 1cm to 10km.

b)Find x, 2x and 3x from the diagram below.
2x+ 3x +82°+128°= 360°.Copy and complete.

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

we need to see the graph to know but

strong positive is if it is going up from left to right in a straight diagonal line (like this /)

strong negative is the same but from right to left (like this \)

weak negative is the same as strong negative but its more straight line still right to left

and weak positive is the same as strong positive but more a straight line still left to right though.
