Identify the y intercept and asymtote for the exponential function f(x)=3^x+2

Feliz [49]

Y-intercept occurs at x = 0.
y = 1 + 2 = 3

$f(x) = 3^{x} + 2$
$\text{Asymptote: } \lim_{x \to \infty} 3^{x} + 2$
$= 2$

Thus, there is a horizontal asymptote at x = 2.

If the variance is 28 kg2 what is the standard deviation?

ikadub [295]

Answer:

The standard deviation is 5.29 kg.

Step-by-step explanation:

The standard deviation is the square root of the variance. Mathematically, we have that:

$S(X) = \sqrt{V(X)}$

In this problem, we have that:

$V(X) = 28$

$S(X) = \sqrt{V(X)}$

$S(X) = \sqrt{28}$

$S(X) = 5.29$

The standard deviation is 5.29 kg.

17. Consider the function f(x, y, z) = xy ln(yz).

Lelu [443]

We can expand

$f(x,y,z) = xy\ln(yz) = xy \ln(y) + xy\ln(z)$

Then using the product and chain rules,

$\dfrac{\partial f}{\partial x} = y\ln(y) + y\ln(z) + \boxed{y\ln(yz)}$

$\dfrac{\partial f}{\partial y} = x\ln(y) + \dfrac{xy}y + x\ln(z) = \boxed{x\ln(yz) + x}$

$\dfrac{\partial f}{\partial z} = \boxed{\dfrac{xy}z}$
