We take the equation <span>d = -16t^2+12t</span> and subtract d from both sides to get
                                         0<span> = -16t^2+12t - d
We apply the quadratic formula to solve for t. With a = -16, b = 12, c = -d, we have
                                         t = [ -(12) </span><span>± √( 12^2 - 4(-16)(-d) ) ] / [2 * -16]</span>
                                           = [- 12 ± √(144-64d) ] / (-32)
                                           = [- 12 ± √16(9-4d)] / (-32)
                                           = [- 12 ± 4√(9-4d)] / (-32)
                                           = 3/8 ±√(9-4d) / 8
The answer to your question is t = 3/8 ±√(9-4d) / 8

steve desposite $1800 per month in his saving bank account. If thi is 20% of the monthly income, find his monthly income​
Vikki [24]

Step-by-step explanation:

Hey there!

The amount deposited= $1800

And it's just 20% of total monthly amount.

Let total amount be "x".

Then;

$1800 = 20% of X

1800 =  \frac{20}{100}  \times x

or, 180000= 20x

or, X = 180000=/20

Therefore, total monthly amount or income was $9000.

Answer:

The product of 3a^2.2a^3\\ is 6a^6

Step-by-step explanation:

We need to find the product of 3a^2.2a^3\\

Using the exponent rule: a^m. a^n = a^{m*n}

So,

3a^2.2a^3\\

Applying above rule:

3.2 (a^{2*3})\\

6a^6

So, the product of 3a^2.2a^3\\ is 6a^6
