Answer:
answer is 15 and second one i dont know yet sorry am doing scoo
Step-by-step explanation:
F(2)=42(2)-100
f(2)= -16
f(2)/-16= -8
3.35kg is minimum and max is 3.44kg
The remaining area that the grass will cover will be given by:
Area=[area of rectangle]-[area of the triangle]
area of rectangle will be:
A1=length*width
=20*8
=160 square feet
The area of the triangle will be:
A2=1/2absin theta
since the triangle is equilateral, all the angles are equal and the size of each angle is 60°. Thus the area will be:
A2=1/2*5*5sin 60
=18.3
thus the remaining area of the grass will be:
Area=160-18.3
=149.7 square feet
Answer:
the answer would be 8s -8
