The solution to the matrix equation is x = 2.6

<h3>What is the solution?</h3>

Following the matrix as given, all the elements in the right hand side would have to be multiplied by X hence we have;

-x   4x            -8    17

6x  3x     =      21   -21

Taking the determinant of both matrices;

-3x^2 - 24x^2 = 168 - 357

-27x^2 = -189

x^2 = -189/-27

x = 2.6

A particle travels along the x-axis such that its velocity is given by v(t) = (t^0.7 + 4t) cos (t^2). What is the average accele
Airida [17]

It's not clear to me what the given interval is supposed to be, so I'll use a generic one, [a, b] with a < b.

The average acceleration of the particle over this interval is given by the average rate of change of v(t),

a_{\rm ave} = \dfrac{v(b) - v(a)}{b - a} = \boxed{\dfrac{(b^{0.7}+4b)\cos(b^2) - (a^{0.7}+4a)\cos(a^2)}{b - a}}

The combined volume of all the tanks at an aquarium is 1.25 X 106 gallons. The aquarium plans to install a new dolphin tank with
DaniilM [7]

1. The combined volume of all the tanks at the aquarium is written in Scientific notation. Keeping this on mind, you can write it as following:

(1.25)(10^{6})=1,250,000gallons

2. Now, you must sum the combined volume of all the tanks and the volume of  the new tank to calculate the total volume of all of them:Vt=1,250,000gallons+250,000gallons\\Vt= 1,500,000gallons

3. Now, you can write the result in Scientific notation, as following:

Vt=(1.5)(10^{6}) gallons

The answer is: (1.5)(10^{6}) gallons
