Answer:

480 students want more field trips.

60 students is 10%.

Step-by-step explanation:

There are 600 students, and 80% want more field trips.

80% of 600 is 0.8*600 = 8*60 = 480 students.

480 students want more field trips.

Firdavs [7]

there are 4 Aces and 4 8's for a total of 8 cards

52 cards in a deck

so probability of picking an Ace or 8 = 8/52

What does it mean if the x-coordinate in an ordered pair is zero? What if the y-coordinate is zero? Both? Explain.

Harman [31]

If the x-axis ordered pair is (0,0) and the y-axis ordered pair is (0,0), it is just where the lines intersect or also known as the origin. Both x and y can have a (0) in it.

for example let's say that you have an ordered pair on the X-axis of (5,0) and a ordered pair on the y-axis of (-3,0) it would look like that^^

or if it was just (0,0) it would be a dot in the middle

Don't know if it helped much, but there ya go

Which of the following choices lists the correct values of a,h, and k for the function f(x)=5x^2

Tju [1.3M]

Answer:

For a general quadratic equation like:

y = a*x^2 + b*x + c

a is the leading coefficient.

And we define the vertex of this as (h, k)

Where h is:

h = -b/(2*a)

and k is the y-value given when we use x = h.

Now, in this case we have:

f(x) = 5*x^2

We can see that the leading coefficient is 5, then a = 5.

To find the value of h we use:

h = -b/(2*a)

there is no lineal term, thus b = 0, then:

h = -0/(2*5) = -0/10 = 0

and k is given by

f(h) = f(0) = 5*0^2 = 0

then k = 0.

Concluding:

a = 5

h = 0

k = 0
