I mean cause 2 x 2 is 4
So 2+2 is 4 you’re just putting 2 into 4 twice
Answer:
Perpendicular lines have a slope that is the negative reciprocal of the given line.
For example, if a given line has the slope 3/2, the the perpendicular line would have the slope -2/3.
For the given line: y = 4x - 7, the perpendicular line would have a slope of -1/4
There isn't enough info in the question to determine the y-intercept. Literally, any y-intercept could work and the line would still be perpendicular. Is the line supposed to pass through a certain point?
Your answer would be something like: y = -1/4 x + b
b is the y-intercept...if your question paper is multiple choice, choose the answer with the slope of -1/4. If it's supposed to pass through a certain point (x,y) replace x and y with the values in that point and solve for b to get the y-intercept.
So, since it is continuously, we need to think of PERT
So, we just plug our numbers in to solve for T

According to me these are the values missing in the question. Here you go with the values
Rain fall, x 10.5 8.8 13.4 12.5 18.8 10.3 7.0 15.6 16.0
Wheat, y 50.5 46.2 58.8 59.0 82.4 49.2 31.9 76.0 78.8
Answer:
1.440
Step-by-step explanation
9(7187.77)-(112.9)(532.8)/square root 9 (1521.39)-112.92 square root 9 (33,836.58)-532.8*532.8=453.6/square root 9.46 square root 2.06 =0.962

Answer: 11(7187.77)-(112.9)(532.8)/square root (1521.39-112.92*112.92 square root 11 (33,836.58532.8*532.8=189.1/square root 1.28 square root 1.82=1.440
Step-by-step explanation:
2.
(2 + √3)(2 - √3)
- x² - y² = (x + y)(x - y)
- x = 2, y= √3
- x² = 2² = 4
- y² = √3² = 3
- (2 + √3)(2 - √3) = 4 - 3 = 1
3.
(6 + √5)/(6 - √5)
- Multiply both numerator and denominator by (6 + √5) to simplify
- (6 - √5) ((6 + √5) = 6² - √5² = 36 - 5 = 31
- (6 + √5)/(6 +√5) = 6² + 2*6*√5 + √5² = 36 + 12√5 + 5 = 41 + 12√5
- (6 + √5)/(6 - √5) = (41 + 12√5)/31
