Answer:
47 -6√10
Step-by-step explanation:
As you know, the area of a square is the square of the side length. It can be helpful here to make use of the form for the square of a binomial.
(a -b)² = a² - 2ab + b²
(√2 -3√5)² = (√2)² - 2(√2)(3√5) + (3√5)²
= 2 - 6√10 + 3²(5)
= 47 -6√10

<em>Check</em>
√2-3√5 ≈ -5.29399 . . . . . . . . note that a negative value for side length makes no sense, so this isn't about geometry, it's about binomials and radicals
(√2-3√5)² ≈ 28.02633
47 -6√10 ≈ 28.02633
The answer is : 2)line segment wy
Answer:
Step-by-step explanation:
For this case we want to find this probability:
Because they want the area to the left of the value. We need to remember that the normal standard distribution have a mean of 0 and a deviation of 1.
We can use the following excel code: =NORM.DIST(-1.55,0,1,TRUE)
And we got:
The other possibility is use the normal standard table and we got a similar result.
Answer:
a. 45° and 135
The non-horizontal rays of ∠ and ∠ will not intersect to form a triangle; the rays will be parallel to each other.
b. 45° and 45°
The non-horizontal rays of ∠ and ∠ will intersect to form a triangle
c. 45° and 145°
The non-horizontal rays of ∠ and ∠ will not intersect to form a triangle.
