It's an irrational number so that means it's value is virtually indiscernible. That's why it seems to go on forever but its most basic form is 3.14.
Answer:
Step-by-step explanation:
f(x) = 2x - 3
f(-2) = 2(-2) -3 = -4 - 3 = -7
f(-1) = 2(-1) -3 = -2 - 3 = - 5
f(0) = 2(0) -3 = 0 - 3 = -3
f(1) = 2(1) -3 = 2 - 3 = -1
f(2) = 2(2) -3 = 4 - 3 = 1
f(3) = 2(3) -3 = 6 - 3 = 3
Given that Pythagorean Theorum is
A^2 + B^2 = C^2, you need to do the opposite.
To find for A^2, you need to:
Subtract B^2 from C^2. This creates the equation of:
C^2 - B^2 = A^2. This works because A^2 + B^2 is C^2, so the opposite must work.
Now if you're looking for A and not A^2, you need to subtract B^2 from C^2 and then square root the difference.
I hope this helps!
Answer:
d=4
Step-by-step explanation:
SUM OF 15 terms = 615
T5 = 53
T5 = a+(n-1)d
53 = a + 4d
4d = 53 - a
d = (53-a)/4
S15 = 15/2 (2a+14d) =615
15/2 [2a + 14×(53-a)/4 ]
=15/2 [ 2a +(53×14 - 14a )/4 ]
=15/2 [ (8a +742 - 14a ) /4]
615×8 = 15(-6a +742)
-6a+72=615×8/15 =41
-6a+72=42
-6a = - 72 + 42 = -30
a = 30/6= 5
a = 5
T5 = 5 + 4×d = 53
4d= 53 - 5 = 48
4d=48
d=4
Common difference is 4
