Answer:
m = -x
Step-by-step explanation:
x +y = y-m
subtract y on both sides which will cancel them out, we are left with
x = -m
multiply both sides by -1 to get rid of the -m
x × -1 = -x, -m × -1 = m
final answer: m = -x
Sequence will look like this:
Term 1: 20 --------- 20 + 5(0)
Term 2: 25 --------- 20 + 5(1)
Term 3: 30 --------- 20 + 5(2)
Term 4: 35 --------- 25 + 5(3)
ETC.
It cab noted that the numbers in the bracket (that is, 0, 1, 2, 3, 3, etc) = n-1
Then, the explicit formula will be;
an = 20 + 5(n-1).
The correct answer is D.
Answer: (B) 130 cm
Proof: If a chord and a line from the centre meet, they must be perpendicular. The line from the centre to the chord also bisects the chord. If the distance from the centre of the circle to the chord is 52 cm and the distance of half of the chord is 39 cm, then you can work out using Pythagoras' Theorem the distance of the radius.
r² = 52² + 39²
r² = 4225
r = 65
Thus, the diameter is 2r = 130 cm
Answer:
A
Step-by-step explanation:
By adding both the x and y coordinates individually and dividing them by two u get the mid point
Step-by-step explanation:
angle measure a =48/2=24°
the arc measure =360°-48°=312°
