Expand And Simplify The Following:

Georgia [21]

For all the questions, we will be using the FOIL pattern.
1. $(x+3)(x-3)(3x+2)$
$(x^2-3x+3x-9)(3x+2)$
$(x^2-9)(3x+2)$
$3x^3+2x^2-27x-18$
2. $(2x+1)(x-2)(x+3)$
$(2x^2-4x+x-2)(x+3)$
$(2x^2-3x-2)(x+3)$
$2x^3+3x^2-11x-6$
3. $(x-3)(2x+1)(3x-2)$
$(2x^2+x-6x-3)(3x-2)$
$(2x^2-5x-3)(3x-2)$
$6x^3-19x^2+x+6$
Hope this helped!

Which set of ordered pairs could be generated by an exponential function ?

lawyer [7]

Answer:

The third choice is the correct answer

Step-by-step explanation:

The set of ordered pairs which could be generated by an exponential function is

$(1,\frac{1}{2}),(2,\frac{1}{4}),(3,\frac{1}{8}),(4,\frac{1}{16})$

If we examine the y-values of this set of ordered pairs, we can see that they have a common ratio of

$r=\frac{1}{4}\div \frac{1}{2}$

$r=\frac{1}{4}\times 2$

$r=\frac{1}{2}$

This makes it exponential.

Helppppppp pleaseee

Viktor [21]

Answer:

$x=2\sqrt{5}$

Step-by-step explanation:

If that is a square, then all sides are the same. Therefore, it's a $\sqrt{10}$ by $\sqrt{10}$ shape. We'll use Pythagorean Theorem to find the diagonal.

$a^2+b^2=c^2\\\sqrt{10}^2+ \sqrt{10}^2=x^2\\10+10=x^2\\20=x^2\\\sqrt{20}=x\\\sqrt{4*5}=x\\ 2\sqrt{5}=x$

Since it's not a fraction, there is no denominator to rationalize. Let me know if you have any other questions!

On a coordinate plane, a curved line crosses the y-axis at (0, 1), crosses the x-axis at (.25, 0), turns at point (2, negative 3

Artyom0805 [142]

Answer:

All real numbers greater than or equal to -3

Step-by-step explanation:

we know that

The curved line could be a vertical parabola opening upwards with vertex at (2,-3)

The vertex is a minimum

The y-intercept is the point (0,1)

The x-intercepts are the points (0.25,0) and (3.75,0)

The domain is the interval -----> (-∞,∞)

All real numbers

The range is the interval ----> [-3,∞)

All real numbers greater than or equal to -3
