Answer:

-x + 2y + 1 > 0

Step-by-step explanation:

Let's find the equation of the dashed line first. From the graph, we can see that it has a slope of 1/2 and a y-intercept of -1/2 so using slope-intercept form, the equation of the line is y = 1/2x - 1/2. Since the line is dashed and not solid, we know that we will use either < or > instead of ≤ or ≥, and because we can see that the shaded region is above the dashed line, we know that the linear equation is y > 1/2x - 1/2. However, we want the answer to be in the form ax + by + c > 0 where a, b, and c are integers so therefore:

y > 1/2x - 1/2

= 2y > x - 1

= -x + 2y + 1 > 0

We firstly calculate the angle at the bottom left of the triangle(theta)..,

; Angle theta...

tan theta = 9/11

Angle theta = tan^-1(9/11)

; Angle theta = 39.3°

Then height x...we then use the smaller triangle..,

; tan (39.3°) = x/5.5

; x = 5.5 tan(39.3°)

Hence... x = 4.5

Part A: The sun produces 3.9 ⋅ 10^33 ergs of radiant energy per second. How many ergs of radiant energy does the sun produce in
expeople1 [14]
(3.9 * 10^33)(1.55 * 10^7) 
3.9 * 1.55 = 6.045
10^33 * 10^7 = 10^40
6.045 * 10^40 <=== ur answer for the 1st one

1.6 * 10^-3 = 1.6 * 1 / 10^3 = 1.6/1000 = 0.0016 <== its probably this one...the 1.6 * 10^-3
