Answer: Suppose you're given the two points (–2, 1) and (1, 5), and they want you to find out how far apart they are. You can draw in the lines that form a right-angled triangle, using these points as two of the corners. It's easy to find the lengths of the horizontal and vertical sides of the right triangle: just subtract the x-values and the y-values.
Step-by-step explanation: Then use the Pythagorean Theorem to find the length of the third side (which is the hypotenuse of the right triangle):
c2 = a2 + b2
...so:
c

=(5−1)
2
+(1−(−2))
2
c = \sqrt{(5 - 1)^2 + (1 - (-2))^2}c=
(5−1)
2
+(1−(−2))
2
c = \sqrt{(4)^2 + (3)^2}c=
(4)
2
+(3)

c = \sqrt{16 + 9} = \sqrt{25} = 5c=
16+9
=
25

all triangles are similar but B and D may be the answer
You know y=mx+ b in slip intercept for which means the y intercept is positive but when it is y=mx-b that means the y intercept is negative
Answer:
Circumference = 10π
Step-by-step explanation:
First identify the circumference formula as such:
2πr (where r ⇒ radius, π ⇒ pi)
Knowing 2 times the radius (2r) in the formula can be rewritten as the diameter, the formula itself can be rewritten as:
πd (where d ⇒ diameter, π ⇒ pi)
If we know the diameter = 10 inches, substitute in the circumference formula πd to get:
π * 10 inches = 10 * π inches = 10π inches
Answer:
Well, if Jenny starts out with 43 apples but then gives 12 to John that would leave Jenny with 31 apples.
Step-by-step explanation:
43 - 12 = 31
(40 - 10) + (3 - 2)
40 - 10 = 30
3 - 2 = 1
30 + 1 = 31
Here is your answer, have a nice day!
