Her findings are as follows: At 6 a. m., the temperature was 52° F. For the next 6 hours, the temperature rose 2° per hour. For the next 4 hours, it rose 1° per hour. The temperature then stayed steady until 6 p. m. For the next 2 hours, the temperature dropped 3° per hour. The temperature then dropped steadily until the temperature was 59° at midnight. I WILL GIVE BRAINLIEST JUST ANSWER PLS!!!

The parameters given are arranged in a tabular form as follows;

At

Time                                            Temperature

6 a. m.                                            56° F

7 a. m.                                             59° F

8 a. m.                                             62° F

9 a. m.                                             66° F

10 a. m.                                           70° F

11 a. m.                                            74° F

12 p. m.                                           74°F

1 p. m.                                             74°F

2 p. m.                                            74°F

3 p. m.                                            74°F

4 p. m.                                            74°F

5 p. m.                                            74°F

6 p. m.                                            74°F

7 p. m.                                            71°F

8 p. m.                                            68°F

9 p. m.                                            65°F

10 p. m.                                           62°F

11 p. m.                                            61.5°F

12 a. m.                                            61°F

With the above table as the data points, the graph can be drawn

From Excel, The Mean temperature is approximately 68.1°F

The standard deviation is 6.079 °F

the answer is f(x)=2x-1

step-by-step explanation:

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).
