Answer:

-0.04

Step-by-step explanation:

4.23-5= -0.77

-0.77*0.04= -0.03

-0.77*0.09= -0.07

-0.07 + -0.03= -0.04

What are the real or imaginary solutions of the polynomial equation x^4-52x^2+576?
klemol [59]
The roots of the polynomial for this case will be x1 = 6, x2 = -6, x3 = 4, x4 = -4.You can solve the polynomial using the resolver after making the variable change u = x ^ 2 so that you have a second degree polynomial. Then return the change to find the missing roots. Attached solution.

Sabena invests $250 in an account that earns 2.4% interest per year compounded continuously. How many years will it take the acc
g100num [7]

Answer:

It'll take 7.5967 years to have $300 on that account.

Step-by-step explanation:

This problem involves a compounded interest compounded continuously, so in order to solve it we must use the formula for those cases as shown below:

M = C*e^(i*t)

Where M is the final value, C is the initial capital, i is the interest rate and t is the total time. We have:

300 = 250*e^(0.024*t)

e^(0.024*t) = 300/250

e^(0.024*t) = 1.2

0.024*t = ln(1.2)

t = ln(1.2)/0.024 = 7.5967

It'll take 7.5967 years to have $300 on that account.

I need help with this problem ​
katrin [286]

Answer:

  (d)  y = -2x +8

Step-by-step explanation:

The parallel line will have the same x-coefficient, eliminating choices B and C. If it goes through point (4, 0), then (x, y) = (4, 0) will satisfy the equation.

  A: 0 = -2(4) +4 = -4 . . . . . not true

  D: 0 = -2(4) +8 . . . . . . . . true

The equation you're looking for is ...

  y = -2x +8

__

<em>Additional comment</em>

Since you know the slope is -2 and a point on the line is (4, 0), you can use the point-slope form of the equation for a line as a starting point.

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

For m = -2, and (h, k) = (4, 0), the equation becomes ...

  y -0 = -2(x -4)

Simplified to slope-intercept form, this is ...

  y = -2x +8

Here's a question for the day, it's simple but it needs explaining.
GuDViN [60]
It is used to see if a graph represents a function because if there is 2 dots or intersecting lines within the other lines then it is not a function. if there is only one line or dot, then yes, it is a function. hope i explained it well.
