Answer:

Anna is 43 years old and Jacob is 41 years old

Step-by-step explanation:

x + 1 + x + 3 = 92

2x + 4 = 92

2x = 92 - 4

2x = 84

x = 41

Lady bird [3.3K]

Given :

Marisa wants to buy a home in Atlanta with a 30-year mortgage that has an annual interest rate of 4.9%.

The house she wants is $250,000 and she will make a $55,000 down payment and borrow the remainder.

To Find :

What is Marisa's monthly mortgage payment to the nearest dollar.

Solution :

Money remains, m = $( 250000 - 55000 ) = $195000 .

Total price after interest, T = m( 1 + rt )

T = 195000×( 1 + 0.049×1)

T = $204555

Monthly payment,

M = \dfrac{m}{12}\\\\M = \dfrac{204555}{12}\\\\M =\$ 17046.25

Therefore, monthly payment is $17046.25 .

Hence, this is the required solution.

Find sin(2x), cos(2x), and tan(2x) from the given information. sin(x) = 5 13 , x in quadrant i
IgorC [24]

The value of trigonometry terms sin(2x) is 120/169 and cos(2x) is 119/169 and tan(2x) is 120/119.

According to the statement

We have given that the sin(x) = 5/13 , x in quadrant iii

And we have to Find the value of cos x using the following:

So, For this purpose, we know that the trigonometry terms are:

sin2(x) + cos2(x) = 1;  

or cos2(x) = 1-sin2(x)

And

cos2(x) = 1-(-5/13)2 =

cos2(x) = 144/169;  

We know that the

In quadrant III both the sin and cos are negative so

cos(x) = -12/13 (after taking square roots).

And

Then tan(x) = sin(x)/cos(x) = (-5/13)/(-12/13) = 5/12.

Now you can use the angle addition formulas to find sin(2x), cos(2x), and tan(2x).

Now

sin(x + x) = sinx * cosx + cosx * sinx

              = (-5/13)*(-12/13) + (-12/13)(-5/13) = 120/169

And

cos(x + x) = cosX * cos(x) - sinx*sinx

               = (-12/13)(-12/13) - (-5/13)(-5/13)

               =  119/169

So,

You could use the tan double angle formula, but it is easiest to use  

tan(2x) = sin(2x)/cos(2x)  = (120/169) / (119/169)

          = 120/119.

So, The value of trigonometry terms sin(2x) is 120/169 and cos(2x) is 119/169 and tan(2x) is 120/119.
