Answer:
2nd option is the correct answer
Step-by-step explanation:
Hope it helps you in your learning process.
The slope of a line and the perpendiular line that intercept will always have a product of -1
If the slope k=-1/6, the perperndicular line can be found by finding the product of the slope and -1
-1= (slope)(perpendicular line slope)
perpendicular line slope= slope(-1)
= -1/6(-1)
= 6
In the chart of the triangle it shows that the variable b is the base. It also give us the equation for area 1/2bh (half of base * height)
Now we just plug in the values we are given
1/2bh
1/2(10*13)
1/2(130)
65
The area of the triangle is 65 ft

Answer:
59.357
Step-by-step explanation:
Ft= αAt-1+ (1-α)Ft-1
Let's take F1=56
F2=0.9(56)+(1-0.9)(56)
F2=56
F3=0.9(59)+(1-0.9)(56)
= 58.7
F4=0.9(53) + (1-0.9)(58.7)
F4=53.57
F5= 0.9(60) + (1-0.9)(53.57)
F5=59.357
