Answer:
-5
Step-by-step explanation:
Set up 2 proportions
562.5 over 12.3 = x over 1
and
353.6 over 8 = x over 1
then cross multiply both of them
12.3x = 562.5
and
8x = 353.6
then divide both of them
round
x = 45.73
and
x = 44.2
based on those answers the petersons were driving faster
Answer:
x is equal to 2
Step-by-step explanation:
2x+4=8
2x=4
x=2
Sine and Cosine are defined over every real number, really over every complex number if you want to go there. So the answer is never.
Pardon me but this seems like a slightly confused question.
When we talk about sinθ , the θ is an angle. θ is just a real number that’s used in the common parameterization of the unit circle,
(x,y)=(cosθ,sinθ)
θ is interpreted as the angle between two rays, one the positive x axis, and one the ray originating at the origin and intersecting the unit circle at (x,y). The angle is given by the arc length of the unit circle cut by the two rays.
There are other ways to parameterize the circle, the most important being
(x,y)=(1−t21+t2,2t1+t2)
which is on the unit circle because of the easily verifiable identity known to Euclid, (1−t2)2+(2t)2=(1+t2)2
The parameterization is defined for all real t but doesn’t quite get the entire unit circle. It’s missing (−1,0). We can allow t=∞ , essentially treating t as a projective parameter, a ratio, and get the entire circle.
Answer:
Linear
Step-by-step explanation:
If you graph this, you start at 1500 on the y-axis. Every time the x-axis increases by 1, the y-axis increases by 200. This forms a straight line, making it exponential since it increases by a constat amount.
