Answer:
C =3.33x
Step-by-step explanation:
The cost of 1 barrette is
9.99/3 sine it is 9.99 for 3 barrettes
or 3.33 per barrette
We want x barrettes
or 3.33*x
C is the total cost
C =3.33x
Answer:
m∠A = 144°, m∠B = 36°
Step-by-step explanation:
Supplementary angles are angles that add up to 180 degrees.
Substitute 4(m∠B) for m∠A.
4(m∠B) + m∠B = 180
5(m∠B) = 180
<u>m∠B = 36°</u>
Substitute 36 for m∠B.
4(36) = m∠A
<u>m∠A = 144°</u>
On a Cartesian plan & from the origin, draw a cercle & a radius(r) that intersect the cercle in P so that to form angle Ф, with the horizontal, then you will notice that the coordinate of P are rsinФ & rcosФ, which are the polar coordinate of P(rsinФ, rcosФ)
If f = (1,2) , (3,4) , (5,6) and g = (2,3) , (4,6) , (6,8) . Find the composite of gof. does fog exist?

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.
