Answer:

Volume = 1.9 in3

Step-by-step explanation:

If the perimeter of the square base is 5 inches, we have that:

Perimeter = 4 * side

5 = 4 * side

side = 1.25 in

Then, to find the volume of the pyramid, we can use the formula:

Volume = (1/3) * side^2 * height

So we have that:

Volume = (1/3) * 1.25^2 * 3.6

Volume = 1.875 in3

Rounding to nearest tenth, we have Volume = 1.9 in3

Find ( f - g)(x).<br><br> f (x) = -2x2 - 2x - 3 and g(x) = 3x2 - 4x - 4
Kruka [31]

Answer:

\large\boxed{(f-g)(x)=-5x^2+2x+1}

Step-by-step explanation:

(f-g)(x)=f(x)-g(x)\\\\\text{We have}\ f(x)=-2x^2-2x-3\ \text{and}\ g(x)=3x^2-4x-4.\\\\\text{Substitute:}\\\\(f-g)(x)=(-2x^2-2x-3)-(3x^2-4x-4)\\\\(f-g)(x)=-2x^2-2x-3-3x^2+4x+4\qquad\text{combine like terms}\\\\(f-g)(x)=(-2x^2-3x^2)+(-2x+4x)+(-3+4)\\\\(f-g)(x)=-5x^2+2x+1

Assume that you randomly select 6 cards from a deck of 52. what is the probability that all of the cards selected are hearts?
Ira Lisetskai [31]
There are 13 hearts in a 52 deck.

You can think about it like this:

P = (13/52)*(12/51)*(11/50)*(10/49)*(9/48)*(8/47) = 0.00008428903476

In what ways does adding a constant or coefficient to a quadratic equation affect the graph?
erastova [34]
<span>If you are adding a constant, then the graph is either raised or lowered k units.

For example.... If you have the graph of y = x^2 and now you add 3, so your new graph of x^2 + 3, will be the same graph as x^2 but raised vertically 3 units.
 
The graph of x^2 - 7 will be the graph of x^2 lowered vertically 7 units.


I hope my answer has come to your help. God bless and have a nice day ahead!</span>

State whether the slope of the line is positive, negative, zero, or undefined.
Rudiy27

The slope of the line is equal to \tan \alpha, where angle \alpha is angle of line incline to the positive x-direction.

  • When \alpha is acute, then slope is positive;
  • When \alpha is obtuse, then slope is negative;
  • When \alpha is right, then slope is undefined;
  • When \alpha is zero, then slope is equal to 0.

In your case angle of inclination is obtuse and slope is negative.

Answer: correct choice is B

Answer:

g(-3) = 1

Step-by-step explanation:

We use the top piece of the function since x = -3

g(-3) = x+4 and x = -3

g(-3) = -3 +4 = 1
