Graph y=cos(x)+3. y=cos(x)+3. Use the form acos(bx−c)+d a c o s ( b x - c ) + d to find the variables used to find the amplitude, period, phase shift, and vertical shift. a=1.

Answer:

Given function: f(x) = cos x + 3

To Draw: Graph of f(x)

As we know graph of trigonometric function cos x is a continuous graph with amplitude 1 .i.e., graph is 1 unit above and 1 unit down from the middle of graph.

If we add a constant to the trigonometric function it does not change any thing it just shift the function up or down according to value of constant.

Here 3 is added to cos x ⇒ Gr pah of cos x will be shifted 3 units upward.

Therefore, The graph we obtain is attached.

N is an odd number.

Answer:

True:

Step-by-step explanation:

First, you should know that the square of any odd number is also odd.

The easiest way to go about this is to plug in an odd number for n. Lets use 3:

Plug 3 into A:

$3^{2} -1=9-1=8$

Plug 3 into B:

$3(3-1)=9-3 = 6$

Plug 3 into C:

$(3-2)^{2} = 2^{2} = 4$

Plug 3 into D:

$3^{2} +2 = 9+2=11$

Plug 3 into E:

$3(3-2) = 9-6 = 3$

Plug 3 into F:

$(3-2)^{2}=1^{2} =1$

Kayla is a basketball player who makes 50 of her 2 point shots and 20 of her 3 point shots find Kayla expected value for a 2 poi

Mumz [18]

Kayla's expected value for a 2- point shot is 1 point.

What is expected value?

The expected value, also known as expectation, expectancy, arithmetical expectation, mean, average, first or moment, is a generalization of the weighted average in the field of probability theory. Informally, the estimation is the arithmetic mean of a significant number of values of a random variable that were independently chosen. A weighted average of all potential outcomes constitutes the expected value of the a random variable with such a finite number of outcomes. When there is a continuum of potential outcomes, integration defines the expectation. The expectation is provided by Lebesgue integration in the measure theory-based axiomatic foundation for probability.

Sol- The expected value is calcuated using the formula:

EV= x.P(x)

where x is the weight/value of the event, and P(x) is the probability of the event occurring.

For a 2-point shot, we have:

X=2

P(x) = 50/100 = 0.5

There for the expected value will be -

EV = 2×0.5 = 1

Thus,

The expected value will be 1 point.

Answer: $3+\sqrt{2}$

Step-by-step explanation:

Given the following expression shown in the picture:

$\frac{7}{3-\sqrt{2} }$

You need to use a process called "Ratinalization".

By definition, using Rationalization you can rewrite the expression in its simplest form so there is not Radicals in its denominator.

Then, in order to simplify the expression, you can follow the following steps:

Step 1. You need to multiply the numerator and the denominator of the fraction by $3+\sqrt{2}$ , which is the conjugate of the denominator $3-\sqrt{2}$ .
