Ken predicts that the average temperature will be -5°c in december. if he predicts the temperature will rise 6°c in
january and fall 3°c in february, which of the following equations can he use to find the sum of the temperatures for those months? check all that apply.
(6 + 3] + 5 = 14
(-5) + (3 + 6] =-4
[(-5) + (-3)] + 6 = -2
5+[(-6) + (-3)] = -4
[6 + (-5)] + (-3) = -2
[(-5) + 6 ]+(-3) = 4

step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
