which rate of change represents the graph shown
a: -200 feet per minute
b: 15 feet per minute
c: 200 feet per minute
d: -15 feet per minute

D

Step-by-step explanation: Since this is depth, we know the answer should be negative. According to the y-axis, the submarine’s “depth below sea level” increases in negativity fast, so it could be answer choice A. BUT, the answer choices also include “per minute,” whereas the graph goes by 10 minutes. Therefore, D is the best option.

the nearest power is 1.651.

means 7482 to the 1.651th power is almost equal to 2489287

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).
