Find the vertex of the parabola and indicate if it is a minimum or maximum for the function f(x) = 3(x - 8)2 + 9 a. vertex at (-8, -9) is a maximum b. vertex at (8, 9) is a maximum c. vertex at (-8, -9) is a minimum d. vertex at (8, 9) is a minimum

Step-by-step explanation:

Sometimes the best thing you can do with this kind of question is just to graph it. The graph is below.  Done on Desmos.   It shows that the min is at (8,9)

So the answer is B.

D

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

f(x) = 3(x - 8)² + 9 is in this form with (h, k) = (8, 9)

• If a > 0 then vertex is a minimum

• If a < 0 then vertex is a maximum

here a = 3 hence

vertex (8, 9 ) is a minimum → D

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

d

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
