First you do -5t squared, you do -5*-5 to get positive 25t and add it to 25t to get 50t and 2. In order to get the answer you have to divide 50 by 2 since 2 needs to also get rid of, so 50/2=25t! So t=25

Step-by-step explanation:

I like to let a graphing calculator or spreadsheet do repetitive calculations. It is well worth the few minutes it takes to learn how to enter a formula into any of the available free spreadsheet programs. The Desmos graphing calculator is amazing in its versatility and usefulness.

There are a couple of things that can help make it easier to construct a table of values.

1) recognize the axis of symmetry for this quadratic is ...

x = -b/(2a) = -25/(2(-5)) = 2.5

So, choosing numbers either side of t=2.5 will cut your work in half.

h(2) = h(3)

h(1) = h(4) . . . for example

2) use Horner form to make manual evaluation easier.

h = (-5t +25)t +2 or = (5 -t)(5t) +2

3. What are the roots of the polynomial y = x³ - 8?

zzz [600]

Step-by-step explanation:

x^3 is a perfect cube, 8 is a perfect cube, so we use difference of cubes.

${a}^{3} - {b}^{3} = (a - b)( {a}^{2} + ab + {b}^{2} )$

Cube root of x^3 is x.

Cube root of 8 is 2

So

a=x

b= 2.

$(x - 2)( {x}^{2} - 2x + 4)$

Set these equations equal to zero

$x - 2 = 0$

$x = 2$

${x}^{2} - 2x + 4 = 0$

If we do the discriminant, we get a negative answer so we would have two imaginary solutions,

Thus the only real root is 2.

If you want imaginary solutions, apply the quadratic formula.

$1 + i \sqrt{ 3 }$

and

$1 - i \sqrt{3}$

Answer : A it is decreased by $70,000

Federal reserve sells $70,000 in treasury bonds to a bank.

Removing cash decreases the money supply . Money supply decreases when exchanging for bonds. That is the immediate effect on money supply.

Federal reserve sells $70,000 . so money supply is decreased by $70,000
