Question 12 (Multiple Choice Worth 5 points)

Mathematics
1 answer:
Norma-Jean [14]3 years ago
8 0

Answer:

y = 5x - 18

Step-by-step explanation:

Points:

Equation of the line:

y = ax + b

(5; 7) and (8; 22)

(5; 7)

7 = 5a + b

(8; 22)

22 = 8a + b

a and b are the same values:

{- 5a - b = - 7

{8a + b = 22

3a = 15

a = 5

5a + b = 7

5.5 + b = 7

25 + b = 7

b = 7 - 25

b = - 18

Equation:

y = 5x - 18

I Hope I've helped you.

Find the points on the curve y=(cosx)/(2 sinx) at which the tangent is horizontal
Lynna [10]
y=\dfrac{\cos x}{2\sin x}=\dfrac12\cot x\implies y'=-\dfrac12\csc^2x=-\dfrac1{2\sin^2x}

The tangent lie is horizontal whenever y'=0. But this is never the case, since \sin^2x>0 and so y' for all x, so horizontal tangents exist.
