PLESE SOMEONE HELP ME I DIDNT STUDY FOR THIS QUIZ

-6 ;

ax² + bx + c ;

-1

Step-by-step explanation:

1)

Give thequadratic equation :

4x² - 6x - 5

The values of a, b, c are the Coefficient of x², x and the constant respectively

Therefore, the value of b is the Coefficient of x = - 6

2.)

Standard form of a quadratic equation is :

ax² + bx + c

a = Coefficient of x² ; b = Coefficient of x ; c is a constant

3.)

2x² - 4x + 7

Axis of symmetry :

-b / 2a

a = 2 ; b = - 4, c = 7

-b / 2a = - 4 / 2(2)

= - 4 / 4

= - 1

f . i can go whenever i feel like it bc it is confidential meaning only i would know how much i deposited besides the bank and they wouldnt care bc when you make a deposit you are using their services which means they are using there competition and gaining more customers

and if they dont well then thats less customers for them in a less profitable way

plz mark brainliest

step-by-step explanation:

part a. the differences are decreasing, so we know the sequence is not arithmetic. the ratios are constant (=3/4), so we know the sequence is geometric.

part b. from part a, we know the common ratio is 3/4, so each term is 3/4 of the one before. the initial term is the number of gallons at h=1.

g[h] = (3/4)·g[h-1]

g[1] = 384 . . . . initial value required for a recursive definition

part c. the general formula for a geometric sequence is

a[n] = a[1]·r^(n-1)

we have a[1] = 384, r = 3/4, and the term number given by h. the formula that follows is

g[h] = 384·(3/4)^(h-1)

part d. filling in the value and doing the arithmetic, we have

g[12] = 384·(3/4)^11 ≈ 384·0.042235136 ≈ 16.2183 . . gallons

part e. each gallon is 4 quarts, so

16.2183 gal × 4 qt/gal = 64.8732 qt
