Answer:
How 'bout them apples?
Step-by-step explanation:
Answer:
x = - 1
Step-by-step explanation:
Given
3x + 2 = y and y = - 1
Substitute y = - 1 into the equation and solve for x, that is
3x + 2 = - 1 ( subtract 2 from both sides )
3x = - 3 ( divide both sides by 3 )
x = - 1
This is verified by the point on the graph with coordinates (- 1, - 1)
Answer:
The third angle is 65 degrees
Step-by-step explanation:
The three angles of a triangle add to 180 degrees
One angle is 25
The second is a right angle which is 90 degrees
The third we will call x
25+90+x = 180
Combine like terms
115+x=180
Subtract 115 from each side
115-115 +x=180-115
x =65
Answer:
12=12
Step-by-step explanation:
4.2÷0.35=420÷35
12=12
12-12=0
0=0
Exact value:
Approximate value: c = 0.08387
Round the approximate value however you need to
==============================================
Work Shown:
Let x = 1+c
We have an infinite geometric series here. The first term is a = 1/(x^2). The common ratio is r = 1/x.
Each new term is found by multiplying the previous term by 1/x.
Assuming -1 < r < 1 is true, the infinite geometric sum is
Plug in S = 11 and solve for x
Use the quadratic formula to find the two solutions
Using these x values, we find that the corresponding r values are
r = 1/x = 1/(1.08387) = 0.92262
r = 1/x = 1/(-0.08387) = -11.92321
The first r value makes -1 < r < 1 true, but the second r value does not. So we will be ignoring the solution x = -0.08387
----------------------------------------------
Using the solution that corresponds to x = 1.08387, we find the value of c is
