Write the expression in algebraic form. [hint: sketch a right triangle.] tan(arcsec(x/3))
WARRIOR [948]

Sketch  a right triangle having adjacent side(A) is given as “3”, hypotenuse side (H) is “x” and assigning angle “a” as the angle between A and H. Using Pythagorean theorem, you will get “square root of x-squared minus 9” as the opposite side (O). Using SOH CAH TOA function, and since secant is the reciprocal of cosine, sec(a) = x/3. Thus, a = arcsec(x/3). The remaining expression tan(a) is Opposite side over Adjacent side which is equal to “square root of x^2 - 9” over "3". Therefore, the algebraic expression would be: tan(arcsec(x/3)) = “sqrt (x^2 -9)” /3. Different answers can be made depending on which side you consider the “3” and “x”.

Need with number 7!
topjm [15]

Answer: 6

SOLUTION

∵segment\frac{}{AB}is tangent to the circle at point C.

∴∠MCA=∠MCB=90°

Suppose \frac{}{MC} =x

From the Pythagorean theorem

MA²=9²+x²

MB²=4²+x²

∴MA²+MB²=AB²

i.e. x^{2} +9^{2} +4^{2} +x^{2} =(9+4)^{2} \\2x^{2} +97=169\\2x^{2} =72\\x^{2} =36\\x=6

We conclude that x=6=\frac{}{MC}

Use rounding or compatible numbers to estimate the difference 762- 332
Ber [7]
You would round 762 to 800, then you would round 332 to 300. You would take those 2 numbers and put them in the questions and it should look like this:
800-300, then you would subtract
Good luck!
