How do you identify the roots of a parabola on a graph?

Mathematics
1 answer:
Phoenix [80]3 years ago
3 0

Answer:

Step 1:

Find the vertex. Since the equation is in vertex form, the vertex will be at the point (h, k).

Step 2:

Find the y-intercept. To find the y-intercept let x = 0 and solve for y.

Step 3:

Find the x-intercept(s). To find the x-intercept let y = 0 and solve for x. You can solve for x by using the square root principle or the quadratic formula (if you simplify the problem into the correct form).

Step 4:

Graph the parabola using the points found in steps 1 – 3.

If XYZ ~ EDF, the measure of angle F is _____ a0°.
hoa [83]

Answer:

63° (same as Z)

Step-by-step explanation:

The question indicates that ΔXYZ is similar to ΔEDF.

By definition, when we indicate that triangle XYZ is similar to the triangle EDF, the order of the letters is important and match the congruent angles.

So, ∠X = ∠E, ∠Y = ∠D and ∠Z = ∠F

It's hard to see because the angles are quite similar in opening (56°, 63° and 61°), and the drawing doesn't seems to be to scale.

But according to the naming convention: ∠Z = ∠F

Since ∠Z = 63°, ∠F = 63°

There are 14 tops you’d like to purchase, but you can only afford six. If you select tops at random, how many different groups o
Slav-nsk [51]

Answer:

3003 different groups of 6tops

Step-by-step explanation:

Using the combination formula, generally, when selecting r number of objects out of a pool of n numbers, this can be done in nCr number of ways.

nCr = n!/(n-r)!r!

If there are 14 tops I'd like to purchase and I can only afford six, the number of ways I can choose this six at random from the 14tops can be done in 14C6 number of ways.

14C6 = 14!/(14-6)!6!

14C6 = 14!/8!6!

14C6 = 14×13×12×11×10×9×8!/8!×6×5×4×3×2

14C6 = 14×13×12×11×10×9/6×5×4×3×2

14C6 = 14×13×12×11/8

14C6 = 3003ways

Why does the equation y=3x+5 Not represent a proportional relationship?
Afina-wow [57]

Answer:

see the explanation

Step-by-step explanation:

we now that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>

In this problem we have

y=3x+5

This is the equation of the line in slope intercept form

where

m=3\\b=5

The given equation not represent a proportional relationship, because the line not pass through the origin

In a proportional relationship the value of b (y-intercept) is equal to zero
