The number of ounces of jam that each jar can hold is 4 large jars and 2 small jars.

<h3>What is Matrix?</h3>

A matrix is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns, which is used to represent a mathematical object or a property of such an object.

Here, from the given matrix by comparing the equations, we have:

l + 2s = 8 ...........(i)

l - s = 2 .............(ii)

Subtract the second equation from the first, to eliminate l

3s = 6

s = 2

Substitute 2 for s in l - s = 2

l - 2 = 2

Add 2 to both sides

l = 4

Thus, the number of ounces of jam that each jar can hold is 4 large jars and 2 small jars.

The number of ounces of jam that each jar can hold is 4 large jars and 2 small jars

<h3>How to solve for the variables?</h3>

The matrix is given as:

$\left[\begin{array}{cc}1&2&1&-1\end{array}\right] \left[\begin{array}{c}l&s\end{array}\right] = \left[\begin{array}{c}8&2\end{array}\right]$

Evaluate the product of the matrices

$\left[\begin{array}{c}l+ 2s&l -s\end{array}\right] = \left[\begin{array}{c}8&2\end{array}\right]$

By comparing the equations, we have:

l + 2s = 8

l - s = 2

Subtract the second equation from the first, to eliminate l

3s = 6

Divide both sides by 3

s = 2

Substitute 2 for s in l - s = 2

l - 2 = 2

Add 2 to both sides

l = 4

Hence, the number of ounces of jam that each jar can hold is 4 large jars and 2 small jars

The solution to 3x2 – 12x 24 = 0 is

zzz [600]

$3x^2 - 12x + 24 = 0 \\ x^2 - 4x + 8 = 0 \\ x= \frac{-b \pm \sqrt{ b^{2} -4ac} }{2a} 
$ ; where a = 1, b = -4 and c = 8
$x= \frac{-(-4) \pm \sqrt{ (-4)^{2} -4 \times 1 \times 8} }{2 \times 1} \\ = \frac{4 \pm \sqrt{ 16 -32} }{2} \\ =\frac{4 \pm \sqrt{ -16} }{2} \\ =\frac{4 \pm 4i }{2} \\ =2+2i \ or \ 2-2i$

A boy flying a kite lets out 300 feet of string, which makes an angle of 38o with the ground. Assuming that the string is straig

Greeley [361]

Answer:

The answer is 184.7 ft

Step-by-step explanation:

You need to find the distance from kite to ground

sin38°/1 = x/300

x = 300 · sin 38

Therefore your answer is 184.7

This is the best way I could explain it....Hope this helps:)

Help needed on this composition math problem

Marrrta [24]

Given that f(x) = x/(x - 3) and g(x) = 1/x and the application of <em>function</em> operators, f ° g (x) = 1/(1 - 3 · x) and the domain of the <em>resulting</em> function is any <em>real</em> number except x = 1/3.

<h3>How to analyze a composed function</h3>

Let be f and g functions. Composition is a <em>binary function</em> operation where the <em>variable</em> of the <em>former</em> function (f) is substituted by the <em>latter</em> function (g). If we know that f(x) = x/(x - 3) and g(x) = 1/x, then the <em>composed</em> function is:

$f\,\circ\,g \,(x) = \frac{\frac{1}{x} }{\frac{1}{x}-3}$

$f\,\circ\,g\,(x) = \frac{\frac{1}{x} }{\frac{1-3\cdot x}{x} }$

$f\,\circ\,g\,(x) = \frac{1}{1-3\cdot x}$

The domain of the function is the set of x-values such that f ° g (x) exists. In the case of <em>rational</em> functions of the form p(x)/q(x), the domain is the set of x-values such that q(x) ≠ 0. Thus, the domain of f ° g (x) is $\mathbb{R} - \{\frac{1}{3} \}$ .
