Answer is 15 combinations of 2 people from 6 will be able to sit on front row.

The formula used is Formula for Combinations.
Where N = Objects equal to 6 people
and r = Sample or 2 Samples

We are to form the combination of 6 objects taken 2 at a time. This can be expressed as 6C2

$6C2= \frac{6!}{2!*4!} \\ \\ 
= \frac{6*5}{2} \\ \\ 
=15$

This means, there can be 15 different combinations of 2 members that can sit in the front row.

So, the answer to this question is option A

What is the decimal form for ten and 54 hundredths

irinina [24]

Answer: 10.54

Step-by-step explanation:

$10 \frac{54}{100}$

Multiply 10 by 100 and add 54

$\frac{10*100+54}{100}=\frac{1000+54}{100} =\frac{1054}{100} =10.54$

3. Graph y=-4x² – 2 and its inverse. (1 point)

madam [21]

Function and its inverse was graphed.

<u>Step-by-step explanation:</u>

y = -4x²- 2

To find the inverse function of y = -4x²- 2 we have to transform the formula to calculate x in terms of y.

y = -4x²- 2

-4x² = y - 2

x = √(y-2) / -4

Now we can change the letters to follow the convention that x is the independent variable and y is the function's value:

y = √(x-2) / -4

Now we have to draw the graph as,

It was side by side that is LHS is the function and the RHS is its inverse.

Answer number 1 please.

Minchanka [31]

$\sf {a}^{2} = {13}^{2} - {5}^{2}$

Formula :

Base²= Hypotenuse² - Perpendicular ²

$\\ \\$

$\hookrightarrow\sf {a}^{2} = {13}^{2} - {5}^{2}$

$\\ \\$

$\hookrightarrow\sf {a}^{2} =169 - 25$

$\\ \\$

$\hookrightarrow\sf {a}^{2} =144$

$\\ \\$

$\hookrightarrow\sf {a} = \sqrt{144}$

$\\ \\$

$\hookrightarrow\sf {a} = \sqrt{12 \times 12}$

$\\ \\$

$\hookrightarrow\sf {a} = 12$

Remember the a² in formula has nothing to do with the a we have to find. :)

10 POINTS IDENTIFY THE SLOPE, Y-INTERCEPT AND GRAPH.<br> 1. Y = 2x + 3<br> 2. Y = 3/4x - 2

Alenkasestr [34]

Answer for problem 1: slope = 2, y intercept = 3

Answer for problem 2: slope = 3/4, y intercept = -2

Explanation:

Both equations are in the form y = mx+b. This is known as slope intercept form. This is because we can read off the values of the slope and y intercept very quickly. We have y = 2x+3 match up with y = mx+b. The m is the slope and b is the y intercept. So m = 2 and b = 3 for this equation. A similar situation happens with the other equation as well. It might help to rewrite the second equation into y = (3/4)x + (-2).
