Answer:

Step-by-step explanation:

C is the correct answer because it represents exactly what the graph shows with the bold lines.

As you can see in the graph, there is no interception between 7 and 12. Therfore, the answer can't be B(because it represents the area between the two numbers).

A isn't the correct answer either because it represents a dot, which is obviously not the case here since there is no dot.

I can't explain why C isn't the right answer, but I hope that explanation that I gave is enough for you to understand ;)

Which of the quadratic functions has the narrowest graph?

charle [14.2K]

Answer:

$y=\frac{1}{8}x^2$

Step-by-step explanation:

A quadratic function has the formula ax² + bx + c

To determine if a graph will be narrow or wide, the leading coefficient, a, will be the factor that determines this
The greater the coefficient, the narrower the parabola
The lesser the coefficient, the wider the parabola

Here all of the functions are in the form ax²

In $y=\frac{1}{8}x^{2}$ , our "a" term is $\frac{1}{8}$
In y = -2x², our "a" term is -2
In y = -3x², our "a" term is -3
In $y=\frac{1}{3}x^{2}$ , our "a" term is $\frac{1}{3}$

We can eliminate the two functions with the negative coefficients because they are much smaller than the two functions with the fractions as coefficients, and will therefore open much wider.

We can now compare the two remaining functions, $y=\frac{1}{8}x^2$ and $y=\frac{1}{3}x^2$

Giving the two fractions common denominators would turn them into $y = \frac{3}{24}x^2$ and $y=\frac{8}{24} x^2$
The equation with the larger fraction will be the parabola that is the narrowest. In this case, it is the $y=\frac{8}{24} x^2$ .
Therefore, $y=\frac{1}{8}x^2$ will have the narrowest graph

GEOMETRY HELP!! WILL MARK BRAINLIEST IF RIGHT!!

Scrat [10]

Answer:

y = 13

z = 11

Step-by-step explanation:

14. We know that if the two triangles are congruent, then the hypotenuses will be the same. So we can say that

6y = 5y + 13

We can solve for y by subtracting 5 y from both sides and find out that y = 13.

15. Again, we know if the triangles are congruent then the two shorter legs will be the same, so we can say that:

3z = z + 22

2z = 22

z = 11
