Congrats!
Step-by-step explanation:
87000 is the rounded number u round down
A triangles degrees add up to 180.
well first 180-138 for angle u which is 42
then do 42+(6y-2)+(8y+14)=180
solve for y.
42+(6y-2)+(8y+14)=180
42+6y-2+8y+14=180
54+14y=180
-54 -54
14y=126
/14 /14
y=9
Answer:
Hard to calculate first one is -1/2
Next one is 2.5/1.5 or 2 its hard to tell because of line (not clear)
Next one is -1/2 I think the numbers are small.

Step-by-step explanation:
We know that L(t) is the tangent to the line A(t) at t = 30
At t = 30:
A (30) ≈ 0.783 →(30, 0.783) = (t, A(t))
A¹ (30) ≈ -0.56
let -0.56 = M
For a linear function, a straight line equation applies which leads to
(y-y₁) = m (x-x₁) ...1
So for this problem we have;
A (t)-0.783 = -0.56 (t - 30)
when there is 0.5 pounds of grass, A (t) - 0.5, then using the equation (1)
(0.5 - 0.783) = -0.56 (t-30)
t = 35.054
≈ 35 days
