Answer:
you have to add them all together to get the right answer.
Step-by-step explanation:
The standard equation is y=ax^2+bx+k and the vertex way is y=a(x-h)(x-h)+x
so the coordinate for x is -b/2a, for your problem a=-4 b=-16 so the coordinate for x is -(-16)/(2*(-4))=-2. Now you have to replace x=-2 in your equation y=-4(-2)^2-16(-2)-11= 5.
The vertex is (-2, 5)
Answer:
The linear function is 
The reasonable domain is 
Step-by-step explanation:
Let
x ----> the time in hours
y ---> the distance in miles
we know that
The linear equation in slope intercept form is equal to
where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem
The slope is 
The y-intercept is 
substitute
<em>Find the domain for x</em>
For y=120 miles
Find the value of x
substitute the value of y in the linear equation and solve for x
therefore
The domain is the interval [0,2]

Step-by-step explanation:
Suppose in a math class of 22 students, 14 are boys and 8 are girls. ... for a girl you have a 8 out of 22 students chance....for an A you have an additional ... 8/22+4/22 = 12/22 = 6/11. for a boy there is a 14 out of 22 chance of being a boy and an ... 14/22 + 6/22 = 20/22= 10/11 ...
