Answer:
C, D and E
Step-by-step explanation:
Assuming
f(x) = √(9−8x)
and the options are:
A. p(x) = √(-8x) and q(x)=9+x
B. p(x) = √(9+x) and q(x)=8x
C. p(x) = √(-x) and q(x)=8x−9
D. p(x)=√(9−x) and q(x)=8x
E. p(x)=√x and q(x)=9−8x
F. p(x)=9−8x and q(x)=√x
G. All of the above
H. None of the above
Substituting in f(x)=p(q(x)) we get:
A. √(-8(9+x)) = √(-72 - 8x)
B. √(9+(8x)) = √(9+8x)
C. √(-(8x−9
)) = √(-8x + 9)
D. √(9−(8x)) = √(9−8x)
E. √(9−8x
)
F. 9−8(√x
) = 9 - 8√x
Answer:
1/4
Step-by-step explanation:
3 divided by 3 is 1, 1 divided by 1 is just a fraction or .25
Answer:
see explanation
Step-by-step explanation:
A
given
= 
( cross- multiply )
5.7f = 34.2 ( divide both sides by 5.7 )
f = 6
-----------------------------------------------------
B
given
= 
( cross- multiply )
3.6g = 92.34 ( divide both sides by 3.6 )
g = 25.65
The tangent secant theorem says
PR × PS = PQ²
4 × (4+5) = PQ²
36 = PQ²
PQ=6
Answer: 6
