Answer:

The monthly bill for Roxy will be = 40+0.20t

Step-by-step explanation:

Let 't' represents the number of text messages sent in a month.

A cell phone company charges $40 per month for unlimited calling

The company charges $0.20 per text message sent. So, for 't' messages, the amount will be = 0.20t

So, the monthly bill for Roxy will be = 40+0.20t

Jacey obtains a 30-year 6/2 ARM at 4% with a 2/6 cap structure in the amount of $224,500. What is the monthly payment during the
beks73 [17]
In this case we have an ARM fixed for 6 years and adjust after the initial first 6 years every 2 years after. The basic idea behind a ARM is that the interest changes periodically, but since our ARM is fixed for 6 years, our going to calculate the monthly payment during the initial period using the formula: m= \frac{P( \frac{r}{12}) }{1-(1+ \frac{r}{12})^{-12t}  }
where
m is the monthly payment
P is the amount
r is the interest rate in decimal form 
t is the number years

First we need to convert our interest rate of 4% to decimal form by dividing it by 100%:
\frac{4}{100} =0.04
We also know from our question that P=224500 and t=30, so lets replace those values into our formula to find the monthly payment:
m= \frac{224500( \frac{0.04}{12}) }{1-(1+ \frac{0.04}{12})^{-(12)(30)}  }
m=1071.80

We can conclude that the monthly payment during the initial period is $1071.58<span />

What’s the answer?!!!!
mel-nik [20]

Answer: YES

Step-by-step explanation:

<u>Concept</u>

In a right triangle, the square of both legs is equal to the length of hypotenuse squared. This is the Pythagorean theorem: a²+b²=c². For more graphical explanation, please refer to the attachment below.

<u>Given</u>

Leg a = 36 in

Leg b = 48 in

Hypotenuse c = 60 in

<u>Solve</u>

a² + b² = c²

(36)² + (48)² = 3600

(60)² = 3600

3600 = 3600

Therefore, the answer is <u>YES</u>

Hope this helps!! :)
