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”.
Answer:
ps is congruent to qr if that's what your asking
Answer: 0.74
Step-by-step explanation:
A= "The person is sick
"
B= "The test gives a positive result"
P(A)=0.03
P(B|A)=0.92
P(B|A')=0.01
P(A')=1-P(A)=1-0.03=0.97
P(B)=P(B|A)P(A)+P(B|A')P(A')=0.92*0.03+0.01*0.97=0.0373
Based in Bayes Rule
P(A|B)=P(B|A)P(A)/P(B)=0.92*0.03/0.0373=0.74

hii I wanna ask something
Answer:
the answer is X=-8 or X= 2
Step-by-step explanation:
subtract 10 from both sides in order to eliminate 10.
x^2 + 6x -16
find two factors of -16 that sum up to 6.
-2 and 8 are two factors of -16 that sum up to 6.
(x-2)(x+8)
x-2= 0, x= 2
x+8= 0, x = -8
