Bad White [126]

Answer:

Step-by-step explanation:

Given the quadratic

d = - 16t² + 12t ← subtract d from both sides

- 16t² + 12t - d = 0 ← in standard form

with a = - 16, b = 12, c = - d

Use the quadratic formula to solve for t

t = ( - 12 ± $\sqrt{12^2-(4(-16)(-d))}$ ) / - 32

= ( - 12 ± $\sqrt{144-64d}$ ) / - 32

= ( - 12 ± $\sqrt{16(9-4d)}$ ) / - 32

= ( - 12 ± 4 $\sqrt{9-4d}$ ) / - 32

= $\frac{-12}{-32}$ ± $\frac{4}{-32}$ $\sqrt{9-4d}$

= $\frac{3}{8}$ ± $\frac{1}{8}$ $\sqrt{9-4d}$

= $\frac{3}{8}$ ± $\frac{\sqrt{9-4d} }{8}$ → D

How many roots does this has?<br>x^2+(2√5x)+2x=-10<br>find Discriminant

Alexxandr [17]

Given:

The equation is

$x^2+(2\sqrt{5})+2x=-10$

To find:

The number of roots and discriminant of the given equation.

Solution:

We have,

$x^2+(2\sqrt{5})x+2x=-10$

The highest degree of given equation is 2. So, the number of roots is also 2.

It can be written as

$x^2+(2\sqrt{5}+2)x+10=0$

Here, $a=1, b=(2\sqrt{5}+2), c=10$ .

Discriminant of the given equation is

$D=b^2-4ac$

$D=(2\sqrt{5}+2)^2-4(1)(10)$

$D=20+8\sqrt{5}+4-40$

$D=8\sqrt{5}-16$

$D\approx 1.89>0$

Since discriminant is $8\sqrt{5}-16\approx 1.89$ , which is greater than 0, therefore, the given equation has two distinct real roots.

A new health drink has 130% of the recommended daily allowance (RDA) for a certain vitamin . The rad for this vitamin is 45 mg.

Maslowich

Answer:

58.5 mg

Step-by-step explanation:

Drink: 130% of RDA of vitamin X

RDA vitamin X = 45mg

130% of 45 = mg in the drink

130% = 130/100 = 1.3

130% of 45 = 1.3*45 = 58.5

So, this new drink has 58.5 mg of vitamin
