Step-by-step explanation:
16. Length of a line = sqaureroot of ((x1-x0)^2 - (y1- y0)^2)
C (2,-3) D (6,3)
CD = sqaureroot of ((6-2)^2 + (3-(-3))^2)
CD = sqaureroot of ( 16 + 36)
CD = sqaureroot of 52 = 2 root 13 = length
17. E (5, - 1) because the point is under the x axis.
Midpoint = ((x1+ x0)/2 , (y1 +y0) /2)
B (8,1) C (2, - 3)
Midpoint of BC = ((2+8)/2 , (-3+1)/2)
= (10/2 , - 2/2)
= (5, - 1)
18. Length of AE
A (4,5) E(5,-1)
Square root of ((5-4)^2 + (-1-5)^2)
Square root of (1^2 + - 6^2)
Square root of ( 1 + 36)
Square root of 37 = root 37

A. z = 0.74
The z-score of 0.74 translates to a percentile of 0.77035. Hence, the area under the standard normal curve to the left of z-score 0.74 is ~0.77.
b. z = -2.16
This z-score translates to a percentile of 0.015386 which is also the numerical value of the area under the curve to the left of the z-score
c. z = 1.02
The percentile equivalent of the z-score above is 0.846. The area is also 0.846.
d. z = -0.15
The percentile equivalent and the area is equal to 0.44.
Answer: The perimeter is 17.52
Step-by-step explanation:
1. You can plot the points, as you can see in the graph attached.
2. As you can see in the graph, the points are:
And the lenghts <em>AB</em> and <em>EA</em> are:
3. To find the other lenghts, you can apply the formula for calculate the distance between two points:
4. Thefore, you have:
5. The perimeter is:
<em>(2a - 3x - 3y)(2a + 3x + 3y)</em>
- Step-by-step explanation:
<em>Hi there !</em>
use formula
<em>a</em><em>² - </em><em>b</em><em>² = (a - b)(a + b)</em>
<em>a</em><em> = 2a</em>
<em>b</em><em> = 3(x + y)</em>
<em />
<em>4a² - 9(x+y)² =</em>
<em>= [2a - 3(x + y)][2a + 3(x + y)]</em>
<em>= (2a - 3x - 3y)(2a + 3x + 3y)</em>
<em />
<em>Good luck !</em>
