Answer:

Option A is correct that is Required additional information is ∠BDC and ∠AED are right angles.

Step-by-step explanation:

We need to find an additional information used to to prove ΔCEA ~ ΔCDB

In ΔCEA and  ΔCDB

    ∠ACE = ∠BCD  ( common angle in both triangle )

if,  ∠AEC = ∠BDC  ( both are right angles )

then ΔCEA ~ ΔCDB by AA similarity criteria.

Therefore, Option A is correct that is Required additional information is ∠BDC and ∠AED are right angles.

Answer:

  • $1,094,748.09
  • $8600.28
  • 11 years, 10 months

Step-by-step explanation:

a) The compound interest formula can be used:

  A = P(1 +r/n)^(nt)

where P is the principal invested at annual rate r compounded n times per year for t years.

  A = $750,000(1 +.038/4)^(4·10) ≈ $1,094,748.09

Tamsyn's account will have a balance of $1,094,748.09 when she retires.

__

b1) The amortization formula is good for this.

  A = P(r/n)/(1 -(1 +r/n)^(-nt))

where P is the amount earning interest at annual rate r compounded n times per year for t years.

  A = $1,094,748.09(0.049/12)/(1 - (1 +0.049/12)^(-12·15)) ≈ $8600.28

Tamsyn can withdraw $8600.28 per month for 15 years.

__

b2) The account balance after n months will be ...

  B = P(1 +r/12)^n -A((1+r/12)^n -1)/(r/12)

Filling in the known values and solving for n, we have ...

  300,000 = 1,094,748.09(1.1.00408333^n) -8600.28(1.00408333^n -1)/.000408333

  300,000 = 1,094,748.09(1.1.00408333^n) -2,106,191.02(1.00408333^n -1)

  -1,806,191.02 = -1,011,442.93(1.00408333^n)

  1.785757 = 1.00408333^n

  n = log(1.785757)/log(1.00408333) = 142.3

After about 11 years 10 months, the account balance will be $300,000.

Question 11 (5 points)
Semenov [28]

Hello :)

here you need to use the slope intercept formula to find your equation:

y= mx+b

b= the y- intercept

m= the slope

we are already given the slope and the x & y

y=-3x+(-2)

your answer would be a) y = -3x - 2
