Answer:
A. 7
B. -3
C. 8
D. 13
E. 5a+17
F. 
+ 8a + 20
Step-by-step explanation:
A. f(1) = 5*1 +2, which equals 7
B. f(-1)= 5(-1)+2 which equals -3
C. g(-3)= (-3)^2+ 2(-3)+ 5 = 9- 6+ 5 = 8.
D. g(2)= (2)^2+ 2(2)+ 5= 4+ 4+ 5= 13.
E. f(a+3)= 5(a+3)+2 = 5a+ 15+ 2= 5a+ 17.
F. g(a+3)= (a+3)^2+ 2(a+3)+ 5= + 6a+ 9+ 2a+ 6+ 5= + 8a+ 20.
The one that is on the top right is the one which is not a linear function
The ratio is 3:5.
You have to divide 72, so the sum of x and y is 72.
Set both expressions equal to each other:
72 divided in a ratio of 3:5 is
27:45.
Answer:
The second one is correct
Step-by-step explanation:
(sorry if it not correct)
theta is in the fourth quadrant where the cosine is positive.
the third side in the triangle = sqrt (4 - 2) = sqrt2
So sin theta = -sqrt2/2 = Second choice (negative because sine is negative in 4th quadrant)
tan theta = - sqrt2 / sqrt2 = -1
