Answer:
How to calculate and derive the formula for the Chord Length of a circle. The formula for the chord length is: 2rsin(theta/2) where r is the radius of the circle and theta is the angle from the centre of the circle to the two points of the chord.
Answer:
the three even integers are -28, -26 and -24.
Step-by-step explanation:
Represent the three numbers as follows:
n
n+2
n+4
Their sum is n + n+2 + n+4 = -78.
Combining the n terms, we get:
3n + 6 = -78, or
3n = -84
Then n = -84/3, or n = -28.
Then the three even integers are -28, -26 and -24.
The answer is <span>amplitude = 2 feet; period = 24 hours; midline: y = 3
x1 - the lowest point
x2 - the highest point
x1 = 1 ft
x2 = 5 ft
t1 = 0
t2 = 24
The amplitude is: (x2 - x1)/2 = (5 - 1)/2 = 4/2 = 2 ft
The period is: t2 - t1 = 24 - 0 = 24 h
The midline is: (x1 + x2)/2 = (5 + 1)/2 = 6/2 = 3 ft</span>
Here, √7 (√14 + √3)
= √7*14 + √7*3
= √98 + √21
= 7√2 + √21
In short, Your Answer would be: 7√2 + √21
Hope this helps!
