The answer would be 81.2 because all you gotta do it 20.3 times 4

5.075 because if 20.3 is 4 times larger than a number, you would divide 20.3 by 4; giving you 5.075.

Explain Pe^(rt) How do I use this formula ?
Montano1993 [528]

Answer:

The equation for "continual" growth (or decay) is A = Pert, where "A", is the ending amount, "P" is the beginning amount (principal, in the case of money), "r" is the growth or decay rate (expressed as a decimal), and "t" is the time (in whatever unit was used on the growth/decay rate).

Step-by-step explanation:

Find the equation of a line that is perpendicular to 4x+6y=1 that has a greater y intercept compared to 2x+3y=18
Marina86 [1]

Answer:

4y = 6x + 40

Step-by-step explanation:

The general equation of a straight line is y = mx + b

m is the slope and b is the y-intercept

let us write both equations in this form;

we have this as;

6y = -4x + 1

y = -4x/6 + 1/6

and;

2x + 3y = 18

3y = -2x + 18

y = -2x/3 + 6

So firstly we want to find an equation that is perpendicular to the first

When two lines are perpendicular, their slopes has a product of -1

The slope of the first line is -4/6

let the slope of the line we want be m

As per they are perpendicular;

-4/6 * m = -1

-4m/6 = -1

-4m = -6

m = 6/4

So now, we want the y-intercept greater than that of the second equation which is a y-intercept of 6

we can choose 10

and we have the equation as:

y = 6x/4 + 10

multiply through by 4

4y = 6x + 40

How do you simplify (-1 - 3 √(3) × (-1 - 3 √(3)
harina [27]

Answer:

4 + 6√(3)

Step-by-step explanation:

Two right parentheses seem to be missing here.  I think you meant:

(-1 - 3 √(3) ) × (-1 - 3 √(3) )

and this is the square of a binomial.  The resulting square is:

1 + 6√3 + 3, or 4 + 6√(3)
