$8x-4y=-16\\\\x-intercept\ for\ y=0:\\\\8x-4(0)=-16\\\\8x-0=-16\\\\8x=-16\qquad\text{divide both sides by 8}\\\\\boxed{x=-2\to(-2,\ 0)}\\\\y-intercept\ for\ x=0:\\\\8(0)-4y=-16\\\\0-4y=-16\\\\-4y=-16\qquad\text{divide both sides by (-4)}\\\\\boxed{y=4\to(0,\ 4)}$

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

What are the solutions to x^2-5x+3=0?

Viktor [21]

Answer:

Step-by-step explanation:

You need to use the quadratic equation

x = $\frac{-b +/- \sqrt{b^2 - 4ac} }{2a}$

Givens

a = 1
b = - 5
c = 3

x = $\frac{5 +/- \sqrt{5^2 - 4a*1*3} }{2} \\$

x =( 5 +/- sqrt(25 - 12) ) / 2

x = (5 +/- sqrt(13) )/2

x = (5 + sqrt(13) / 2

x = 4.303 rounded

x = (5 - sqrt(13) ) /2

x = .6972
