Answer:

sin x° = Opposite / Hypotenuse

x = 3.38

Step-by-step explanation:

sin 70° = x / 3.6

sin 70° × 3.6 = x

x = 0.93969262079 × 3.6

x = 3.38289343483 ~ 3.38

Kathy Parker's employer pays 65% of the total cost of her $5,489 health insurance premium. What is her biweekly deduction for th

zzz [600]

Answer:

$73.89

Step-by-step explanation:

We have been given that Kathy Parker's employer pays 65% of the total cost of her $5,489 health insurance premium.

This means Kathy pays 35% of her health insurance premium.

Let us find 35% of $5489.

$\text{Amount of health insurance premium paid by Cathy per year}=\frac{35}{100}\times\$5489$

$\text{Amount of health insurance premium paid by Cathy per year}=0.35\times\$5489$

$\text{Amount of health insurance premium paid by Cathy per year}=\$1921.15$

As we are asked to find Cathy's biweekly deduction for the insurance we will divide amount of premium paid by Cathy by 26 as biweekly is paid 26 times per year.

$\text{Cathy's biweekly deduction}=\frac{\$1921.15}{26}$

$\text{Cathy's biweekly deduction}=\$73.89$

Therefore, Cathy's biweekly deduction for the insurance is $73.89.

Let A(t) represent the amount of money in a bank account at time t years. The rate at which the account is increasing is proport

nikdorinn [45]

Answer:

Step-by-step explanation:

If A(t) represent the amount of money in a bank account at time t years.

The rate at which the account is increasing is proportional to the amount of money in the account, which is modeled by the differential equation:

$\dfrac{dA}{dt}=kA$

First, we solve this differential equation

$\dfrac{dA}{A}=kdt\\$Taking Integrals\\ln A =kt+C, C a constant of integration\\Taking exponents of both sides\\A(t)=Ce^{kt}\\When t=0, A(t)=\$500\\500=C\\Therefore:\\A(t)=500e^{kt}$

At the moment when the amount of money in the account is $1000, the amount is increasing at a rate of $50 per year.

When A(t)=$1000, $\dfrac{dA}{dt}=50$

Therefore:

$50=1000k\\k=50/1000=0.05$

Substituting into our result from A(t) above:

$A(t)=500e^{0.05t}$
