No because ex:1times5=5 because 1 goes into 5 fiverimes

Answer:
x=πn, n∈Z
Step-by-step explanation:
if sin²2x=1-cos²2x, then
1-cos²2x-2cos2x+2=0; ⇒ cos²2x+2cos2x-3=0; ⇔ (cos2x+3)(cos2x-1)=0;
Answer:
23 x + 62
Step-by-step explanation:
Simplify the following:
5 (4 x + 12) + 3 x + 2
5 (4 x + 12) = 20 x + 60:
20 x + 60 + 3 x + 2
Grouping like terms, 60 + 20 x + 3 x + 2 = (20 x + 3 x) + (60 + 2):
(20 x + 3 x) + (60 + 2)
20 x + 3 x = 23 x:
23 x + (60 + 2)
60 + 2 = 62:
Answer: 23 x + 62
There's a lot of information missing here, and the given list of choices is basically incomprehensible.
Suppose J (a, b) and K (c, d) are two points in the plane. We can trace out the line segment JK joining these points with the function
r(t) = (1 - t) (a, b) + t (c, d)
where 0 ≤ t ≤ 1.
Let P be the point that divides JK into line segments JP and PK having a length ratio of 2:5. Then JP is the point 2/7 of the way along JK, so that the coordinates of P are
P = r(2/7) = 5/7 (a, b) + 2/7 (c, d) = ((5a + 2c)/7, (5b + 2d)/7)
and in particular the x-coordinate of P is (5a + 2c)/7.
