the weight of a cylindrical can varies jointly with the height of the can and the square of the cans radius. A 4-inch high can w

Bess [88]

With the information given we have:
$W=k.h.r^2$
Where W is the weight, k is the proportionality constant and r is the radius of the can's radus. Remember that the weight varies jointly so this key word means that you need to multiply the mentiones parameters by a proportionality constant k.
We simply need to reorganize the expression and isolate k for the frst answer:
$k=\frac{W}{h.r^2}$
Replacing by all the appropiate values we get:
$k=\frac{16}{(1.5)^2.4}\approx1.78$
For the second part knowing k we have:
$W=\frac{16\times 4.5\times 2^2}{(1.5)^2\times 4}=32 ounces$

Write an algebraic expression for:<br><br> The product of 12 and the sum of a number and negative 3

lbvjy [14]

The product of 12 and the sum of a number and negative 3 is 12(x - 3)

<h3>How to represent algebraic expression?</h3>

An algebraic expression is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, multiplication etc.).

In other words, an algebraic expression is a mathematical statement that contains a combination of numbers, symbols, variables and mathematical operators.

Therefore, the product of 12 and the sum of a number and negative 3 is as follows:

let

the number = x

Hence,

12 × (x + (-3))

12 × (x - 3) = 12(x - 3)

What method(s) would you choose to solve the equation: x^2 + 2x - 6 = 0

BlackZzzverrR [31]

It would be B. "Regular" factoring without the quadratic formula can't be done. Completing the square will work easily since the coefficient on the squared term is a 1. I personally wouldn't graph this to find the solutions, although you could with and x/y chart to give you enough coordinates to plot the graph correctly.
