Explanation:
The pancreas is a glandular organ with many different functions. Let's analyze each answer choice.
A. Produce insulin and glucagon
This is a pancreatic function. These are hormones the pancreas secretes.
B. Produce hormones that control blood sugar levels.
This is also a function. The hormones mentioned in answer choice A control blood glucose. They communicate with the body to absorb or release sugar so homeostasis can be maintained.
C. Secrete digestive enzymes.
This is another function. The pancreas makes liquid called pancreatic juice. This has enzymes that help in digestion and breaking down food.
Choices A, B, and C are all correct. So, <u>choice D </u>must be correct.
Answer:
36.5 cm²
Explanation:
The perimeter of the smaller shape = 20 cm and The area of the smaller shape = 18.6 cm²
The perimeter of the bigger shape = 28 cm
The length and breadth of the smaller shape is increased by a factor of k to produce the larger shape.
If the length of the smaller shape = l and its width = w. The perimeter of the smaller shape = 2(l + w) = 20
Since The length and breadth of the smaller shape is increased by a factor of k to produce the larger shape, the length of the larger shape = kl and its width = kw. Therefore the perimeter of the larger shape = 2(kl + kw) = 2k (l + w) = 28 cm
To find k, divide the perimeter of the larger shape by the perimeter of the larger shape:
The area of the smaller shape = l * w = 18.6 cm²
The area of the larger shape = kl * kw = k² * l * w = 1.4² * 18.6 cm² = 36.5 cm²
