Answer:
40 feet to the nearest foot.
Step-by-step explanation:
The tree , the distance from the base of the tree on the ground (30 ft) and the distance from this point to the top of the tree form a right triangle.
So if the height of the tree is h:
tan 53 = h / 30
h = 30 tan53
h = 39.81 feet.
Answer:
y = -x + 17
Step-by-step explanation:
Gradient of the normal:
(8-5)/(9-6) = 3/3 = 1
Gradient of the tangent:
-1/1 = -1
y = -x + c
8 = -9 + c
c = 17
y = -x + 17
Answer:
87
Step-by-step explanation:
3×9 + 10×36/6
27 + 10×6
27 + 60
87
a square as the distance between the lengths and widths are 3
Answer:
1000. 100x10=1000 100+100+100+100+100+100+100+100+100+100=1000
100/1000=1/10
