I guess non of them, as all of them can be expressed by fractions.
Answer:
A = 90.25 pi in^2
Step-by-step explanation:
The circumference is given by
C = 2*pi*r
19pi = 2*pi*r
Divide each side by 2 pi
19pi / 2 pi = 2*pi*r/ 2pi
9.5 = r
The area is given by
A = pi r^2
A = pi ( 9.5)^2
A = 90.25 pi in^2
Answer:
angle 1 should equal to 54.
angle 2 should equal to 126.
Step-by-step explanation:
2x - 8 + 4x + 2 = 180
2x + 4x - 8 + 2 = 180
6x - 6 = 180
6x - 6 + 6 = 180 + 6
6x = 186
6x ÷ 6 = 186 ÷ 6
x = 31
---------------------------------------------
2x - 8 = A1
2(31) - 8 = A1
62 - 8 = A1
54 = A1
-----------------------------------------------
4x + 2 = A2
4(31) + 2 = A2
124 + 2 = A2
126 = A2
Answer:
Y = 3X. Y is Dependent, X is Independent. Table is below.
Step-by-step explanation:
y = 3x would be the equation. Y represents the amount of websites in total, and X represents the amount of weeks. This means that Y is the Dependent, while Y is the Independent.
X | 1 | 2 | 3 | 4 | 5
-----|-----|-----|-----|-----|------
Y | 3 | 6 | 9 | 12 | 15
If f = (1,2) , (3,4) , (5,6) and g = (2,3) , (4,6) , (6,8) . Find the composite of gof. does fog exist?
drek231 [11]
Answer:
.
does not exist.
Step-by-step explanation:
It is given that,
We need to find the composition gof.
Now,
So, .
We need to check whether exist of not.
If range of g(x) is subset of domain of f(x), then we can say composition function exists.
Now,
Range of g(x) = {3,6,8}
Domain of f(x) = {1,3,5}
Since range of g(x) is not a subset of domain of f(x), then we can say composition function does not exist.
