Evaluate the expression (-6) squared
fiasKO [112]

\huge \boxed{\mathfrak{Question} \downarrow}

  • Evaluate the expression ⇨ (-6) squared.

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

\sf (-6)  \: squared

This will be equal to..

\sf( - 6 ) ^ { 2 }

Multiply -6 by itself (squaring a number means to multiply the number by itself twice)

\sf- 6 \times  - 6  \\

-6 multiplied by-6 will get you 36 as the answer.

=    \boxed{\boxed{\bf \: 36}}

A rectangle has a length of 2 6√<br> and width of 6√<br> . Find the perimeter of the rectangle.
Angelina_Jolie [31]
  • L=2root6
  • B=root6

\\ \rm\Rrightarrow Perimeter=2(L+B)

\\ \rm\Rrightarrow Perimeter=2(2\sqrt{6}+\sqrt{6})

\\ \rm\Rrightarrow Perimeter=2(3\sqrt{6})

\\ \rm\Rrightarrow Perimeter=6\sqrt{6}

1. A weight suspended from a spring is set into oscillating motion by compressing it to a
Naya [18.7K]

Question:

Complete question for this is to find the equation for this and may be the graph.

Explanation:

As for the oscillation motion, initially peak is occurring hence it will be a cosine function with peak value of 3(cm).

To calculate time period, the whole cycle should be 360°

i.e.

cos (Xπ.t) = cos (360)

as the cycle completes at 1.2 sec hence by putting t=1.2, answer should be 360.

i.e.

X*180*t=360

X*180*1.2=360

X=5/3

So, the required equation is

f(x)=3.cos(5\frac{\pi }{2}.t)

Graph for this equation is attached here with this answer.

In graph,

x-axis: t=0 ~ t=1.2

y-axis: f(x)=-4 ~ f(x)=4
