Answer:
Step-by-step explanation:
85=2x(x^2+3)(2x+5)
85=2x(2x^3+5x^2+6x+15)
85=4x^4+10x^3+12x^2+30x
4x^4+10x^3+12x^2+30x-85=0
2x^2(2x^2+5x+6)+30x-85=0
shoot, this isn't possible with quadratic, maybe you can get somewhere from here
Answer:
the slope is
Step-by-step explanation:
Given: 4y - 7x = 10; solve y
4y - 7x = 10; add 7x to both sides to isolate the 4y variable
4y = 7x + 10; now divide by 4
y = x + ; reduce the fraction
y = x + ; the slope is
(x-10)^2 + (y+4)^2 = 16
use the formula for equation of circle
(x-h)^2 + (y-k)^2 = r^2
<span>In 6 years, you will have $17,109.13 at 6% semiannually compounded.
</span><span>Plug the values into the following formula: A x [(1 + (R/2))^(N x 2)]. In the formula, "A" represents the initial investment amount, "R" represents the annual interest rate as a decimal and "N" represents the number of years you will own the investment. In this example, the formula would be $20,000 x [(1 + (0.06/2))^(5 x 2)].</span>
