Temperatures and Elevation
Choose the letter for the best answer.
Use the scatter plot for Exercises 4–6.

Elevation (ft)
4 What does the point (0, 400)
represent in this scatter plot?
A the temperature at an elevation
of O feet
B the elevation at a temperature of
58°F
C the elevation at a temperature of
0°F

Temperature (°F)
D the temperature at an elevation
of 500 feet
5. Which best describes the correlation
between the temperatures and the
elevations in the scatter plot?
F strong positive
Gweak positive
H strong negative
J weak negative
6. Which equation best represents the
line of best fit?
A y=-16x + 400
B y = -15x + 300
C y = 15x - 300
D y= 16x – 400

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q

a≈380.13mi² would be your answer if the radius was 11 miles

simplifying

7ln(x + 2.8) = 11.2

reorder the terms:

7ln(2.8 + x) = 11.2

(2.8 * 7ln + x * 7ln) = 11.2

(19.6ln + 7lnx) = 11.2

solving

19.6ln + 7lnx = 11.2

solving for variable 'l'.

move all terms containing l to the left, all other terms to the right.

reorder the terms:

-11.2 + 19.6ln + 7lnx = 11.2 + -11.2

combine like terms: 11.2 + -11.2 = 0.0

-11.2 + 19.6ln + 7lnx = 0.0

the solution to this equation could not be determined.

step-by-step explanation:

i searched it on google but it says that the solution to this equation could not be determined but i hope that it you a little.
