Given that the sec A = 13/5 and A is in QIV, determine exact value for the sin A.
AysviL [449]

Answer:

The exact value of sin A is opp/hyp = -12/13

Step-by-step explanation:

If A is in Quadrant IV then the "opposite side" is negative and the "adjacent side" is positive.  Since sec A = hyp / adj = 13 / 5 and since opp^2 + adj^2 must add up to hyp^2,   Therefore y = √(hyp^2 - adj^2), or

y = -√(13^2 - 25) = -√144 = 12.

The exact value of sin A is opp/hyp = -12/13

The mass of a cylinder made of barium with a height of 2 inches depends on the radius of the cylinder as defined by the function
svp [43]

Answer:

r=22.07\ in

Step-by-step explanation:

<em><u>The correct function is</u></em>

m(r)=7.188\pi r^{2}

we have

System of equations

m=7.188\pi r^{2} -----> equation A

m=11,000 -----> equation B

Solve by substitution method

substitute equation B in equation A

11,000=7.188\pi r^{2}

Solve for r

Divide by 7.188π both sides

r^{2}=\frac{11,000}{7.188\pi}

square root both sides

r=22.07\ in
