Answer:

Step-by-step explanation:

The altitude of ΔYES is the geometric mean between 'n' and 'm'

Proportion → $\frac{m}{a}=\frac{a}{n}$

The shorter leg 'a' is the geometric mean between 'h' and 'm'

Proportion → $\frac{h}{a}=\frac{a}{m}$

The longer leg 'b' is the geometric mean between 'h' and 'n'

Proportion → $\frac{h}{b}=\frac{b}{n}$

The function Q(x)=2x^2-kx+18. For what value of k does Q(x) have one distinct real solution? (NEEDS TO BE DONE WITHIN 2 HOURS!)

Aliun [14]

Answer:

k = 12

Step-by-step explanation:

Given:

The equation $Q(x)=2x^2-kx+18$

To find:

Value of $k = ?$ for which the given equation has one distinct real solution.

Solution:

The given equation is a quadratic equation.

There are always two solutions of a quadratic equation.

For the equation: $ax^{2} +bx+c=0$ to have one distinct solution:

$b^2 - 4ac = 0$

Here,

a = 2,

b = -k and

c = 18

Putting the values, we get:

$(-k)^2 - 4\times 2\times 18 = 0\\\Rightarrow k^2 = 18\times 8\\\Rightarrow k^2 =144\\\Rightarrow k = 12$

The equation becomes:

$Q(x)=2x^2-12x+18$

And the one root is:

$2(x^2-6x+9 ) = 0\\\Rightarrow 2(x-3)^2=0\\\Rightarrow x = 3$

gayaneshka [121]

Answer:

x+4y is not change because it's parallel what changes is the result 8 + 4 × 2 = 16 so the equation is x + 4y = 16

What’s the multipcative inverse of 1/4

LuckyWell [14K]

Hey!

Answer:

4/1

Step-by-step explanation:

The multiplicative inverse of a number is the reciprocal of it. (a/b → b/a).

Basically you divide 1 by the other number. (1 ÷ 1/4 = 4 or 4/1).

Hope This Helps :)
