The area of the arrow given in the figure is 610 square cm
<h3>Area of composite figure</h3>
The given figure is made up of rectangle and triangle. The area is expressed as:
Area = Area of rectangle + area of triangle
Substitute the given parameters
Area of the arrow = (15*20) + 0.5(31 * 20)
Area of the arrow = 300 + 310
Area of the arrow = 610 square cm
Hence the area of the arrow given in the figure is 610 square cm

It is the first question u are looking for
A is INCORRECT because here we have degrowth and growth
B is INCORRECT because the decay factor is 2% or 0.02 , not 0.2
C is CORRECT, the function is which is used to calculated the area of rainforest at time t is given by 1156.25(1 -0.02 )^t
D is INCORRECT, if we plug in t=100 in the above equation , we get = 1156*(1-0.02)^100 = 153 square miles of forest. So it will not be wiped out
E is CORRECT, if we plug in t =35, we get = 1156*(1-0.02)^35 = 570 square miles. So more than half will be cut in 35 years
F is INCORRECT becuase domain goes beyond 100 years as shown by option D
So, correct options are C and E
Answer:
126
Step-by-step explanation:
3.5 times 12 = 126
Answer:
70
Step-by-step explanation:
The angle is equal to the degree of the arc, so the angle, 2x, is equal to 140°.
140 = 2x
140/2 = x
70 = x
x is equal to 70.
