Explanation:
When the dough is folded, it increases by a constant factor. We can model the growth of the thickness using the exponential growth model
Where:
Initial thickness, = 2mm
Growth factor, r =8%=0.08
We want to find the smallest number of times Soon Yi will have to roll and fold the dough so that the resulting dough is at least 2.5mm.
i.e When
Therefore, the smallest number of times Soon Yi will have to roll and fold the dough so that the resulting dough is at least 2.5mm thick is 3.
The length of x to the nearest tenth is; D: 38.6 m
<h3>Trigonometric ratios</h3>The image of the triangle is missing and so i have attached it.
From the image attached, we can find the value of x by using trigonometry ratio.
We see that;
- AB = x
- AC = 10
- ∠BAC = 75°
Thus;
10/x = cos 75
10/x = 0.2588
x = 10/0.2588
x = 38.64 m
Approximating to the nearest tenth gives;
x = 38.6 m
