The distance between points A and B
(-1/8)-(-6/8) = 5/8
Answer:
B, D
Step-by-step explanation:
Solve all equations:
A.
This is false equality, so this equation has no solutions.
B.
This equality is true for all values of x, so this equation has infinitely many solutions.
C.
This equation has the unique solution.
D.
This equality is true for all values of x, so this equation has infinitely many solutions.
E.
This equation has the unique solution.
Answer:
find b: since the triangle is right angle triangle apply the Pythagorean theorem
c²+b²=d²
b²=d²-c²
b²=16²-12²
b²=256-144
b²=112
<h2>b=√112 = 4√7</h2>
the sum of the angle of the triangle=180
( in top Δ abd ) sin Ф=opp/hyp
sinФ=b/d=4√7/16= √7/4 radian
convert to degrees : √7/4 *180/π= 37.91 almost 38 degrees
<h2>which makes A= 38 degrees ( adjacent angles are equal when they have common side and do not overlap)</h2>
find a=?? apply law of cosine
a²= d^2 + c^2 − 2dc cosA
a²=16² + 12²-2(16)(12)cos38
a =√(16² + 12²-2(16)(12)cos38)
<h2>a=9.87 rounded to the nearest hundredth</h2>
(i hope it is right )
Answer:
154
Step-by-step explanation:
If the 7th term is 77 and the 8th term is 231, you have to subtract them and get your answer.
231-77=154
154 is the common ratio.
(if another person gets the same answer it is probably correct)
A:12/3 = -4
b:-12/3 = -4
c:-12/-12 = 4
e:-5/5 = -1
f:5/-5 = -1
g:-5/-5 = 1
