Answer:

[3, -1]

Step-by-step explanation:

The computation is performed element by element, as you appear to have figured.

2f -g = 2[4, 1] -[5, 3] = [2·4 -5, 2·1 -3] = [8-5, 2-3]

2f -g = [3, -1]

A small square garden has an area of 25 square yards. How long is each side of the garden?

insens350 [35]

<h3>♫ :::::::::::::::::::::::::::::: // Hello There ! // :::::::::::::::::::::::::::::: ♫</h3>

➷ Area = l x w

We already have the area so substitute that in:

25 = l x w

For a square, all sides have the same length

Therefore, to get the length, simply square root 25

This would give you an answer of 5 yards.

What best describes the asymptote of an exponential function of the form f(x)=b^x?

horrorfan [7]

It depends on the value of b

Exponential functions are defined for positive values of the base [ŧex] b [/tex]. Also, they're not defined if $b=1$ , or at least let's say that this is a trivial case, since it is the constant function 1.

Case 0<b<1:

If the base sits between 0 and 1, the exponential function is constantly decreasing. The explanation is quite intuitive, assume for the sake of simpleness that b is rational. If it sits between 0 and 1, it means that it can be written as a fraction p/q, with p<q. So, if you give a large exponent to b, you obtain

$\frac{p^x}{q^x},\quad p^x \ll q^x \text{ as } x \to \infty$

On the other hand, if you consider negative exponents, you switch numerator and denominator and then raise to the same exponent the fraction q/p, which gets larger and larger.

So, if 0<b<1, we have

$\lim_{x \to -\infty} b^x = \infty,\qquad \lim_{x \to \infty} b^x = 0$

and thus 0 is a horizontal asymptote as x tends to (positive) infinity.

Case b>1:

This case is very similar, except all roles are inverted. Now you start with a fraction p/q where p>q. So, with positive, large exponents you get

$\frac{p^x}{q^x},\quad p^x \gg q^x \text{ as } x \to \infty$

And as before, negative exponents switch numerator and denominator, so the fraction becomes q/p and thus you have

$\lim_{x \to -\infty} b^x = 0,\qquad \lim_{x \to \infty} b^x = \infty$

So, again, 0 is a horizontal asymptote, but this time for x tending towards negative infinite.

Nostrana [21]

Answer:

D) the standard error for her sample is 15

Step-by-step explanation:

Samantha is 95% certain that between 50% and 70% of the first year students agree that they should be able to bring a car to campus.

Here

95% is the confidence level.
The range between 50% and 70% indicates 95% confidence interval.
60% is the average proportion of the first year students at her university think they should be able to bring a car to campus.
10% (0.1) is the margin of error from the mean

Since standard error can be obtained by dividing margin of error by the z-statistic of the confidence level which is 1.96. The standard error for her sample $\frac{0.1}{1.96}$ does not equal to 15.
