Is a-b parallel to c-d? Explain

You spin a spinner and flip a coin. Find the probability of the compound event.

vampirchik [111]

Answer:

3/6 or 1/2

Step-by-step explanation:

There are 2 even numbers on the spinner. It would be 2/4 or 1/2 for the probability the spinner will land on one of the numbers. The coin is a 1/2 probability you will land on tales. If you add both sides of the coin and the 4 numbers on the spinner you would get 6. You would then add only the even and tales together. That would be 3 out of 6.

As the domain values approach infinity, the range values approach infinity. As the domain values approach negative infinity, the

Firdavs [7]

Limits at infinity truly are not so difficult once you've become familiarized with then, but at first, they may seem somewhat obscure. The basic premise of limits at infinity is that many functions approach a specific y-value as their independent variable becomes increasingly large or small. We're going to look at a few different functions as their independent variable approaches infinity, so start a new worksheet called 04-Limits at Infinity, then recreate the following graph.

plot(1/(x-3), x, -100, 100, randomize=False, plot_points=10001) \ .show(xmin=-10, xmax=10, ymin=-10, ymax=10) Toggle Explanation Toggle Line Numbers

In this graph, it is fairly easy to see that as x becomes increasingly large or increasingly small, the y-value of f(x) becomes very close to zero, though it never truly does equal zero. When a function's curve suggests an invisible line at a certain y-value (such as at y=0 in this graph), it is said to have a horizontal asymptote at that y-value. We can use limits to describe the behavior of the horizontal asymptote in this graph, as:

and

Try setting xmin as -100 and xmax as 100, and you will see that f(x) becomes very close to zero indeed when x is very large or very small. Which is what you should expect, since one divided by a large number will naturally produce a small result.

The concept of one-sided limits can be applied to the vertical asymptote in this example, since one can see that as x approaches 3 from the left, the function approaches negative infinity, and that as x approaches 3 from the right, the function approaches positive infinity, or:

and

Unfortunately, the behavior of functions as x approaches positive or negative infinity is not always so easy to describe. If ever you run into a case where you can't discern a function's behavior at infinity--whether a graph isn't available or isn't very clear--imagining what sort of values would be produced when ten-thousand or one-hundred thousand is substituted for x will normally give you a good indication of what the function does as x approaches infinity.

Which of the following are properties of a perfect square trinomial? Select all that apply.. A.Neither of the perfect squares ca

aliya0001 [1]

Definition 1: Perfect squares are numbers or expressions that are the product of a number or expression multiplied to itself (7 times 7 is 49, so 49 is a perfect square).

Definition 2: Binomials are algrebraic expressions containing only two terms.

Definition 3: Trinomials are algebraic expressions that contain three terms. 

Perfect square trinomials are algebraic expressions with three terms that are created by multiplying a binomial to itself. There are two formulas for perfect square trinomials:
$(a+b)^2=a^2+2ab+b^2, \\ (a-b)^2=a^2-2ab+b^2$ .
From these formulas you can see that:
A. "Neither of the perfect squares can have a minus sign" is true statement;

B. "The first and third terms must be perfect squares" is true statement;

C. "If the perfect square terms are $a^2$ and $b^2$ then the other term must be $(ab)^2$ " is false statement;

D. "None of the above is a property of a perfect square trinomial" is consequently false statement.
