Answer:

p(1) = 6

Step-by-step explanation:

The basic idea is to put 1 wherever you see x. That gives you ...

p(1) = 2·1² +3·1 +1

The powers of x are all 1 when x=1, so the value of p(1) is just the sum of the coefficients:

p(1) = 2 + 3 + 1

p(1) = 6

What is the vertex of the parabola

Answers

Answer:

lallalalaal hiiiiii

Step-by-step explanation:

The standard form is written as y = ax ^2 + b + c

Using the given equation:

A = -5, b = 30 and c = 7

The x value of the vertex = -b/ 2/a = -30/2(-5) = -30/-10 = 3

To find the y value replace x with the x value and solve for y:

Y = -5(3)^2 + 30(3) + 7

Y = -45 + 90 + 7

Y = 52

The vertex is (3,52)

-
m(x) = -2(x - 6)² + 18
m(x) = -2(x - 3)(x-9)
Write one of the zeros.

Answers

Answer:

m(x) = -2(x - 3)(x - 9)

One of the zeros of the function is x = 3

Step-by-step explanation:

The form that most quickly reveals the zeros (or "roots") of the function is:

m(x) = -2(x - 3)(x - 9)

To find the zeros of the function, we set m(x) equal to zero:

-2(x - 3)(x - 9) = 0

From this equation, we can see that the zeros (roots) of the function occur when either (x - 3) equals zero or (x - 9) equals zero. Solving these equations gives us the zeros:

x - 3 = 0

x = 3

x - 9 = 0

x = 9

Therefore, one of the zeros of the function is x = 3.

Hope this helps!

A chocolate shop sells chocolates with a variety of different fillings.

hazelnut 68
caramel 8
orange 8

What is the probability that a randomly selected chocolate will have caramel filling?

Write your answer as a fraction or whole number.

Answers

Answer:

There is a [tex]\frac{2}{21}[/tex] chance of picking caramel-filled chocolate.

Step-by-step explanation:

To set this up, you need to make it a fraction. The denominator of the fraction is how many total chocolates you can pick from. You can figure this out by adding all of the chocolate choices together:

68 hazelnut + 8 caramel + 8 orange = 84 chocolates.

The numerator is defined by the number of caramel chocolates, in this case it is 8. That means the fraction will look like:

[tex]\frac{8}{84}[/tex]

Now that can be simplified down. I divided the top and bottom both by 4 to get [tex]\frac{2}{21}[/tex] and that is as far down as it can go. Therefore that is the probability you will get a caramel-filled chocolate.

Niamh runs 6 km in 30-minutes what is the average speed in km h

Answers

Answer:

12 km/hr

Step-by-step explanation:

The average speed is 12 km/hr.

It is to find the average speed in km /h.

What is speed?

Speed is measured as the ratio of distance to the time in which the distance was covered.

Given that :

Distance covered by Niamh = 6 km

Time =30minutes=30/60hour

=1/2hour

∴ The average speed=Total distance/Total time

The average speed=6*2/1

The average speed=12 km/hr.

So, the average speed is 12 km/hr.
