The concept to answer this question can be bought from physics.
The Snell's law of refraction says that, the ration of sine of angle of incidence to the the sine of angle of refraction is constant for a given media.
This means;
(sinθ1)/(sinθ2) = k
Where θ1 = angle of incidence and
θ2 = angle of refraction
k = constant
(sinθ1)/(sinθ2) = k
sinθ2 = k/sinθ1
= k/sin25
= k/0.422618261
= 2.366k
The angle of refraction, θ2 = anti-sin(2.366k)
Answer:
3 1/11
Step-by-step explanation:
8 1/2 x 4/11
Change to an improper fraction
(2*8+1)/2 * 4/11
17/2 * 4/11
68 /22
Divide the top and bottom by 2
34/11
Change back to a mixed number
11 goes into 34 3 times with 1 left over
3 1/11
Answer:
d = sqrt(x2-x1)^2 + (y2-y1)^2
d = sqrt(4-3)^2 + (-3)^2
d=sqrt(1+9)
d=sqrt10
d=3.2
Let me know if this helps!
First plug 32 in for x 14(32)t=46
Now solve for t
448t=46
T=46/448 which can be simplified to 23/224
I think answer is y=7/8x-5/2
