Mathematics

maxonik [38]4 years ago

Answer:

Minimum: (1,4) Maximum: None

Step-by-step explanation:

The vertex 1,4 is the minimum because the equation opens upwards. You can simply graph the equation at desmos.com calculator

There is no maximum because the equation continues upward forever

You can also look up symbolab's maximum/minimum calculators.

Answer: 11.5

Step-by-step explanation:

It’s delta y over delta x so you would take any two combination of coordinates and subtract and divide. I used 57.50-23 over 5-2... this gets you 34.5 over 3. This is also equal to 11.5 :)

If p is true andº q is false, then p-&gt; "qis<br> false.<br> always<br> never<br> sometimes
Nataliya [291]

Answer:

Always.

Step-by-step explanation:

If p is true and q is false, the p -> q is never true.

The logic gates are used here.

Here, the symbol -> is for implication. Implication p-> q means that if p is true then q must be true.

So let us look at all the questions one by one.

If p is true and q is false, the p -> q is always, sometimes, never true.

p -> q

true -> false

The true should imply true so the given statement will never be true.

Writing an equation of a probably given the vertex and focus
White raven [17]

The equation of the vertical parabola in vertex form is written as

y=\frac{1}{4p}(x-h)^2+k

Where (h, k) are the coordinates of the vertex and p is the focal distance.

The directrix of a parabola is a line which every point of the parabola is equally distant to this line and the focus of the parabola. The vertex is located between the focus and the directrix, therefore, the distance between the y-coordinate of the vertex and the directrix represents the focal distance.

p=1-6=-5

Using this value for p and (3, 1) as the vertex, we have our equation

y=-\frac{1}{20}(x-3)^2+1
