You can see it's a geometric sequence because the ratio is constant (
).
The nth term of a geometric sequence:
It has to be the sum for term 4 through term 15, so n=4 and the number above the sigma is 15.
Your answer:
Answer:
its corresponding angles postulate
Step-by-step explanation:
Elevation per minute
elevationchange=-8212
timechange=214
elevation per minute=-8212/214=
-8132/214-80/214=
-38-40/107=
-38 and 40/107
answer is -38 and 40/107 ft per minute
Answer:
55 degrees
Step-by-step explanation:
Given that a circle and inside two chords with same arc length.
We are to find the angle between the two chords.
Given that two arcs subtend angle 125 degrees at the centre.
Let us join the two ends of chords to make the figure as a triangle inside a circle.
The triangle is isosceles as two arcs and hence chords are equal.
By central angle theorem we have the two equal angles as 1/2 (125) = 62.5
Hence we have a triangle with two equal angles 62.5 and another angle 1.
By triangle sum of angles theorem
angle 1+62.5+62.5 = 180
Hence angle A = 180-62.5-62.5 = 55 degrees.
Answer:
slope-intercept form: y=5x-3 point-slope form: y-7=5*(x-2)
Step-by-step explanation:
Y-y1=m(x-x1)
plug in the values and you get y=5x-3
