HELP NEEDED IMMEDIATELY! I'M GETTING DESPERATE!

TiliK225 [7]

Answer:

The number of different possible values are {-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7}.

Step-by-step explanation:

Given : For an integer n, the inequality $x^2 + nx + 15 < 0$ has no real solutions in x.

To find : The number of different possible values of n ?

Solution :

The given inequality is $x^2 + nx + 15 < 0$ have no solution then the discriminant must be less than zero.

i.e. $b^2-4ac$

Here, a=1, b=n and c=15

${n}^{2} - 4 \times 1 \times 15 \: < \: 0$

${n}^{2} - 60 \: < \: 0$

$n^2$

$n$

i.e. $- 7.75 \: < \: n \: < \: 7.75$

The integer values are {-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7}.

If 1800ml of a juice drink is 15% grape juice, how much grape juice should be added to make a drink that is 20% grape juice?

Svetach [21]

Answer:

112.5 mL

Step-by-step explanation:

Let x represent the amount of grape juice to add. Then the total amount of grape juice in the mix is ...

0.15(1800) +x = 0.20(1800+x)

270 +x = 360 + 0.2x . . . . . . eliminate parentheses

0.8x = 90 . . . . . . . . . . . . . . . subtract 270+0.2x

x = 90/0.8 = 112.5 . . . . . . . . divide by the coefficient of x

112 mL of grape juice should be added to make a mix that is 20% grape juice.

what is the height of a rectangular prism that has a length of 4 cm width od 5 cm and a volume of 120 cm3?

Stella [2.4K]

h = 6 cm

The formula for the volume of a rectangular prism is $V = lwh$ . In order to figure out the height you need to divide $wh$ from both sides of the equation. As a result, you'd get $\frac{V}{lw}=h$ . Then you'd rearrange the equation so that it's $h=\frac{V}{lw}$ .
