The daily low temperature in Guangzhou, China, varies over time in a periodic way that can be modeled by
a trigonometric function.
The period of change is exactly 1 year. The temperature peaks around July 26 at 78°F, and has its
206
minimum half a year later at 49° F. Assuming a year is exactly 365 days, July 26 is per of a year after
January 1.
Find the formula of the trigonometric function that models the daily low temperature T in Guangzhout
years after January 1, 2015. Define the function using radians.
T(t) =(

question

what is the value of the third quartile of the data set represented by this box plot? a. 19 b. 21 c. 26 d. 29

answer

c

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

just pick what you think i need more time let me know if this
