Wow that's a big threat. Don't want you to fail or loose your girlfriend so I'll help you out...

We know that x is 3 and y is -6 so replace the x and y with their corresponding numbers in the equation: 36x-8 $y^{2}$ . So...

36(3) - 8 $(-6)^{2}$

Multiply 36 and 3 together:

108 - 8 $(-6)^{2}$

Square -6

108 - 8(36)

Multiply -8 by 36

108 - 288

Subtract them and you get...

-180

Hope this helped! And tell your gf not to break up with you since you got this question right lol

The vertex of this parabola is at (3,-2). when the x-value is 4, the y-value is 3. whatis the coefficient of the squared express

zubka84 [21]

Answer:

<em>The coefficient of the squared expression in the parabolas equation will be 5.</em>

Step-by-step explanation:

<u>The vertex form of parabola</u> is: $y=a(x-h)^2 +k$ , where $(h,k)$ is the vertex point and $a$ is the coefficient of $x^2$ term.

The vertex is given as $(3,-2)$ . That means, $h=3$ and $k=-2$

So, the vertex form will be: $y=a(x-3)^2-2$

Given that, when the x-value is 4, the y-value is 3. So, plugging these values into the above equation, we will get.....

$3=a(4-3)^2-2\\ \\ 3=a(1)^2-2\\ \\ a=3+2=5$

Thus, the coefficient of the squared expression in the parabolas equation will be 5.

Four girls and six boys are in a Spanish club. Three of the people will be chosen at random to represent the group in a photogra

snow_tiger [21]

Answer:50 %

Step-by-step explanation:

Given

There are 4 girls and 6 boys in a club

Probability of choosing 1 girl and 2 boys is

$=\dfrac{\text{No of ways of choosing 1 girl and 2 boys }}{\text{No of ways of choosing 3 member out of 10 member}}$

No of ways of choosing 1 girl and 2 boys $=^4C_1\times ^6C_2$

$P=\dfrac{^4C_1\times ^6C_2}{^{10}C_3}$

$P=\dfrac{4\times 15}{10\times 3\times 4}$

$P=\dfrac{15}{30}=\frac{1}{2}$

i.e. $50\%$
