Answer: 4
Step-by-step explanation:
Distance between two points is calculated by:
Step 1: locate the coordinates points
Point 1- (x1,y1) = (-9, 17)
Point 2- (x2,y2)= (-9, 13)
Formular to find distance between two given points on a line
= √(x2−x1)2 + (y2−y1)2
Distance between two points =
√(−9− −9)2 + (13 −17)2
=√02 + (−4)2
= √0 + 16
= √16
= 4
Therefore, distance between points (-9, 17) and (-9, 13) is 4

Answer:
4.9361
Step-by-step explanation:
Rieman sum = ∫∫ΔA
ΔA = ΔxΔy
Δx = = = pi/2 = Δy
ΔA = pi/2 * pi/2 =
Evaluating at the four corners
=
= 2
∫∫ΔA = 2 * = = 4.9361
Step-by-step explanation:
30 days period multiply by 7 days
=210 therefore our answer is =210
3x - 13 = 8
<em><u>Add 13 to both sides.</u></em>
3x = 21
<em><u>Divide both sides by 3.</u></em>
x = 7
Now that we have the value of x we can solve x - 4.
7 - 4 = 3
The value of x is 7, and the answer to the second expression is 3.
