A: The right triangle formed by point C and B and point (1,63) is similar to the one formed by C, A and point 2,63 by doubling the sides. That implies that the slope of CB is the same as the slope of CA.

B: The initial value at t=0 tells us that the shark is initially at a depth of 63 meters and is diving at a constant rate of (105-63)/1= 42 meters per minute.

3.The legs of a right triangle are equal. Given the length of the legs, find the length of the hypotenuse. Round

Zepler [3.9K]

Answer:

1.41a

Step-by-step explanation:

Let ABC is a right triangle with equal legs AB =BC.

Hence, ∠B is 90° and CA is the hypotenuse.

Now, applying Pythagoras Theorem, we can write

CA² = AB² + BC²

Let us assume that each legs AB = BC = a.

Therefore, CA² = a² +a² = 2a²

⇒Hypotenuse or CA = a√2 = 1.41a { Round to the nearest tenth} (Answer)

A regulat pentagon has side lenghts of 5.8cm and apothem of 4cm. calculate its perimeter and area

Kryger [21]

PENTA = 5.

a regular polygon has all equal sides, so if one side is 5.8, all are, so the perimeter for this pentagon with 5 sides is 5.8 + 5.8 + 5.8 + 5.8 + 5.8 = 29.

$\bf \textit{area of a regular polygon}\\\\ A=\cfrac{1}{2}ap~~ \begin{cases} p=perimeter\\ a=apothem\\ \cline{1-1} p=29\\ a=4 \end{cases}\implies A=\cfrac{1}{2}(4)(29)\implies A=58$
