Answer:

H. x = 1 , slope is undefined

Step-by-step explanation:

The slope of a vertical line is always undefined.

If you think about it, no matter what y value you use, the x will always be 1 (In this equation). Such as:

(1, 5)

(1, 8)

(1, -12914)

(1, 272)

With x always being one, it forms a vertical line parallel to the y-axis

5. Whitney deposits $9,000 for 2 years. She compares two different banks. State

Volgvan

Answer:

a. $ 381.969,

b. $ 369.171,

c. Kings Savings

d. Reliability.

Step-by-step explanation:

∵ Amount formula in compound interest,

$A=P(1+r)^t$

And, amount formula in continuously,

$A=Pe^{rt}$ ,

Where,

P = principal amount,

r = rate per periods,

t = number of periods,

a. In State bank,

P = $ 9000, r = 2.1% = 0.021, t = 2 years,

Also, interest earned compound annually,

Thus, amount,

$A=9000(1+0.021)^2 = 9000(1.021)^2 = \$ 9381.969$

So, interest earned = A - P = 9381.969 - 9000 = $ 381.969,

b. In Kings Savings,

P = $ 9000, r = 2.01% = 0.0201, t = 2 years,

Also, interest earned compound continuously,

Thus, amount,

$A=9000e^{0.0201\times 2} = \$ 9369.171$

So, interest earned = A - P = 9369.171 - 9000 = $ 369.171,

c. ∵ 369.171 > 381.969

Thus, King saving pays higher interest.

d. Since, the other factors might affect Whitney's choice besides interest would be reliability.

Last Saturday, the MoviePlex Iheater sold 1,456 tickets. The theater sold 6 times as many regular price tickets as it sold disco

blagie [28]

Well, one divides by 7, actually, because the total number of tickets is 6+1 times the # of discount tickets. That is, 1,456/7. You don't need to actually perform this division.
