B since you can rewrite it as (2x+7)(x-4)=0 and you can solve it and you get B
5/2.5 = 2
10*2 = 20ft
The flagpole is 20ft tall.
Answer:
g(x) has the greater max: 11 versus 6
Step-by-step explanation:
One can readily discern the max value of the graph; it is 6 and occurs at x =1.
Regarding the function g(x) = (-1/2)x^2 + 4x + 3: Find the vertex, which also represents the max value:
Here the coefficients are a = -1/2, b = 4 and c = 3, so that the axis of symmetry is:
x = -b/(2a), which here is x = -4 / ( 2·[-1/2] ) = -4 / (-1) = 4
At x = 4, the function (y) value is
g(4) = (-1/2)(4)² + 4(4) + 3, or
g(4) = -8 + 16 + 3, or 11
This is greater than the max value of the graphed function.
Answer:
The following statement below are reasons why random sampling are preferred over other sampling:
O. A random sample is a fair way to select a sample because each member of the population has an equal chance of being selected.
O. A random sample is always the easiest way to select a sample from a population.
O. A random sample is likely to give you a sample that is representative of the population.

Answer:

Step-by-step explanation:
we are given a quadratic equation
we know that quadratic equation is same as equation of parabola
so, we can use formula

Focus is

now, we can compare it with given focus
=(8,-8)
we get


Directrix is

we are given directrix =-6

we got two equations as


now, we can add both equations
and we get




now, we can find 'a'


now, we can plug back all values
and we get
So, equation of parabola is
