option C <B = 54° ( answer is attached )
Answer:
The equation in vertex form is:

Step-by-step explanation:
Recall that the formula of a parabola with vertex at
is given by the equation in vertex form:

where the parameter
can be specified by an extra information on any other point apart from the vertex, that parabola goes through.
In our case, since the vertex must be the point (2, 1), the vertex form of the parabola becomes:

we have the information on the extra point (0, 5) where the parabola crosses the y-axis. Then, we use it to find the missing parameter
:

The, the final form of the parabola's equation in vertex form is:

Answer:
x=7
Step-by-step explanation:
Opposite of subtraction is adding so you do 4+10=14 so that means that x equals seven because 2x7 equals 14.
A. C (6) = 15.24; C 11 = 22.09.
C (6) represents the cost, $15.24, of delivering flowers to a destination that is 6 miles
from the shop.
C (11) represents the cost, $22.09, of delivering flowers to a destination that is 11 miles
from the shop.
b.
Answer:
if the smaller one with ratio 4 cost 272 then eat will the larger one of ratio 5cost how much so u cross multiply 4 is for 272 so wat Abt 5 n u get 340 for the cost of the larger one
