20 Points- Which of the following is true for f of x equals the quotient of the quantity x squared plus 9 and the quantity x min

tangare [24]

Answer:

There is a non-removable discontinuity at x = 3

Step-by-step explanation:

We are given that

$f(x)=\frac{x^2+9}{x-3}$

We have to find true statement about given function.

$\lim_{x\rightarrow 3}f(x)=\lim_{x\rightarrow 3}\frac{x^2+9}{x-3}$

= $\infty$

It is not removable discontinuity.

x-3=0

x=3

The function f(x) is not define at x=3. Therefore, the function f(x) is continuous for all real numbers except x=3.

Therefore, x=3 is non- removable discontinuity of function f(x).

Hence, option B is correct.

As part of a new advertising campaign, a beverage company wants to increase the dimensions of their cans by a multiple of 1.10.

Firdavs [7]

Answer:

New can holds $112.25\,\,cm^3$ more than the old can

Step-by-step explanation:

Given: Diameter of the can is 6 cm and height is 12 cm such that volume of can is $339.12\,\,cm^3$

Dimensions of the can are increased by a multiple of 1.10

To find: Difference between the volume of new can and volume of old can

Solution:

Volume of can (v) = $339.12\,\,cm^3$

Let r, h denote radius and height of the can.

Let R, H denotes radius and height of the new can.

r = diameter/2 = $\frac{6}{2}=3\,\,cm$

h = 12 cm

R = $3(1.1)=3.3.\,\,cm$

H = $12(1.1)=13.2\,\,cm$

New volume (V) = $\pi (R)^2H=\pi(3.3)^2(13.2)=451.37\,\,cm^3$

So,

$V-v=451.37-339.12=112.25\,\,cm^3$

Use the Division Property of Equality to complete the following statement. If 4x = 5y, then x = ?

SpyIntel [72]

Answer:

$\boxed {\tt x=\frac{5y}{4}}$

Step-by-step explanation:

We are given the equation:

$4x=5y$

We want to solve for x, so we must isolate x.

x is being multiplied by 4. The inverse of multiplication is division. Use the Division Property of Equality and divide both sides of the equation by 4.

$\frac{4x}{4} =\frac{5y}{4}$

$x=\frac{5y}{4}$

Using the Division Property of Equality, x is equal to 5y/4
