The vertex of a parabola is (-1.5, -12.5), and its y-intercept is (0, -8)

1 answer:

4 0

Best to find the equation of the parabola first:

Its equation is y+12.5 = (x+1.5)^2, or y = -12.5 + (x+1.5)^2

Check the first possible x-intercept: let x = -2. Does y come out to 0?

y = -12.5 + (-0.5)^2 = -12.5 + 0.25. This is not equal to 0, so (-2,0) is not an x-intercept of this parabola. Continue checking each possible x-intercept until you find the right one (or ones).

Cups come in packages if 12 and lids come in packages of 15. What is the least number of cups and lids that corrine can buy if s

Valentin [98]

What you need to do is find the smallest multiple that they both have (i forgot what that is called) list them like this:
12: 24 36 48 60 72
15: 30 45 60 75
60 is the lowest number that they both can multiply to
60 cups/lids is the answer

This circle is centered at the origin, and the length of its radius iS 6. What is

VikaD [51]

$\sf{\qquad\qquad\huge\underline{{\sf Answer}}}$

The equation of circle in standard form can be represented as :

$\qquad \sf \dashrightarrow \:(x - h) {}^{2} + (y - k) {}^{2} = r {}^{2}$

where,

h = x - coordinate of centre = 0

k = y - coordinate of centre = 0

r = radius of circle = 6 units

now, let's plug in the values :

$\qquad \sf \dashrightarrow \:(x - 0) {}^{2} + (y - 0) {}^{2} = 6 {}^{2}$

$\qquad \sf \dashrightarrow \: {x}^{2} + {y}^{2} = 36$

That's the required equation of circle.

The graph Plot of the given results shown represents; A relation only

<h3>How to interpret a scatter plot?</h3>

For it to be a function, then no x-value can produce more than 2 y-values. However, we see that at x = 25, y has 2 values. Similarly, at x = 15, y has two values.

Thus, the graph plot can only be a relation as it is not a function as seen from the points plotted in the graph.

The complete question is;

Mrs. Anderton is giving a test in her third-period class. She has decided to record the amount of time that each student takes to finish the test (in minutes) and compare that to the grade each student receives on the test (out of 100). A plot of her results is below. Which of the following does this situation represent?

A. both a relation and a function

B. a function only

C. neither a relation nor a function

D. a relation only
