L 2.4.5 Quiz: Converting Parabolic Equations Question 8 of 10
The standard form of the equation of a parabola is y= x2 - 6x + 14.
What is the vertex form of the equation?
A. y= (x - 3)2 + 5
O B. y=(x-3)2 + 15
C. y = (x+3)(x-3) + 5
O D. y=(x-3)2 + 23

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

3

60 + 3

63
