Line AB is = to 180 so you know that angle a is equal to 70. And since the triangles are the same angle 1 =70°

If they are parallel and you extend the lines you can see that the angle A will be the same value as angle 1
180-110=angle 1
angle 1=70

After 6 years, what is the total amount of a compound interest investment of $35,000 at 4% interest, compounded quarterly?
sammy [17]

Answer:

<h2>$9441</h2>

Step-by-step explanation:

The interest will be compounded quarterly every year, it means in each year the interest will be calculated 4 times.

In 6 years in total 6 \times4 = 24 times the interest will be calculated.

The yearly interest rate is 4%. Hence, the quaterly interest rate will be \frac{4}{4} = 1%.

Hence, after calculating 24 times, the amount will be turned to 35000 \times (\frac{101}{100} )^{24} = 44440.7127≅  44441.

Hence, the total compound interest is $(44441 - 35000) = $9441

4. What is the system of equations that describes the following graph?
GarryVolchara [31]

Answer:

The system of inequalities is

y

y>0.25x

Step-by-step explanation:

step 1

Find the equation of the dashed line with negative slope

The line passes through the points

(0,-2) and (-2,0)

Find the slope

m=(0+2)/(-2-0)=-1

Find the equation of the line in slope intercept form

y=mx+b

we have

m=-1\\b=-2

substitute

y=-x-2

The solution of the inequality is the shaded area below the dashed line

therefore

The equation of the inequality A is

y

step 2

Find the equation of the dashed line with positive slope

The line passes through the points

(0,0) and (4,1)

Find the slope

m=(1-0)/(4-0)=0.25

Find the equation of the line (direct variation)

y=kx

we have

k=0.25

substitute

y=0.25x

The solution of the inequality is the shaded area above the dashed line

therefore

The equation of the inequality B is

y>0.25x

therefore

The system of inequalities is

y

y>0.25x
