Answer:
f(r) = 2πr
Step-by-step explanation:
You know the formula for circumference in terms of radius is ...
C = 2πr
You are being asked to write this as a function named "f". That will be ...
f(r) = 2πr
Answer:
14
Step-by-step explanation:
Since all sides are half of greater triangle.Then 7 × 2 = 14 is length of greater hypotenuse.
Suppose two triangles with similar conditions
1^2+1^2=2
Hypotenuse=2^1/2
We assume another triangle which is exactly double of previous triangle I.e
2^2+2^2=8
Hypotenuse=2×2^1/2
Which is exactly twice of previous triangle.
Hence proved hyootenuse is double of smaller triangle I.e 14
Area of a triangle= bh/2b=4in h=8in8x4/2=16in
there are 4 triangles
4x16=64
area of a rectangle=bh
4x4=16
64+16=80in^2
Answer:
Step-by-step explanation:
A) 4x + 6 = 2x - 12
Subtract 6 from both sides
4x + 6 - 6 = 2x - 12 -6
4x = 2x - 18
Subtract 2x form both sides
4x - 2x = 2x - 18 - 2x
2x = -18
B) 24 = 6x - 18
6x - 18 = 24
6x - 6*3 = 24
6(x - 3) = 24
Divide both sides by 6
x - 3 = 4
Use the given slope and point and put it into the point-slope formula
y - y1 = m ( x - x1 )
1 is your x value (x1) and 9 is your y value (y1). M = -3
In point slope form, the answer is
y - 9 = -3 ( x - 1 )
