Answer:
x= 35
Step-by-step explanation:
Cos x = Sin( 20+x)
Sin ( 90 – x) = Sin(20+x)
90 – x = 20+x
2x = 70
x = 35
The answer is Y+1=-32(x-1)
Answer:
3n + 5
Step-by-step explanation:
You can't add 5 to 3n. So in 5 years he will 3n + 5.
Answer:

Step-by-step explanation:
Here, we have to convert the equation to slope-intercept form so we can find the perpendicular slope:




Since our slope is
, then that means the slope perpendicular to it is
.
Now we find our new y-intercept so that the line will pass through the point (-7,7):





Therefore, the equation of the new line is 
Min = 0; Q₁ = 0; Median = 2; Q3 = 2; Max = 8
Step-by-step explanation:
Assume that your sorted data are
0, 0, 0, 0, 0, 0, 0, 1, 1, 1, ´ 3, 3, 4, 5, 8 2, 2, 2, 2, 2, 2, 2, 3, 3,
1. Minimum
