Find the square root of 3.6 upto 2 decimal places. *With Solution I need*
almond37 [142]

Answer:

The square root is 1.90

Step-by-step explanation:

Given

x = \sqrt{3.6}

Required

Find x

Express 3.6 as 36/10

So, we have:

x = \frac{\sqrt{36}}{\sqrt{10}}

This gives

x = \frac{6}{\sqrt{10}}

Rationalize

x = \frac{6}{\sqrt{10}}*\frac{\sqrt{10}}{\sqrt{10}}

x = \frac{6\sqrt{10}}{10}

Using a calculator

\sqrt{10} \approx 3.16

So, we have:

x = \frac{6*3.16}{10}

x = \frac{18.96}{10}

x = 1.896

Approximate

x = 1.90

Box all final answers. Little to no work will reccive little to no credit! I. (5 points) Let A and B be 4 x 4 matrices, with det
FinnZ [79.3K]

Answer: a) -6, b) 32, c) -48, d) 9, e) -12

Step-by-step explanation:

Since we have given that

A and B are 4 × 4 matrices.

Here,

det (A) = -3

det (B) = 2

We need to find the respective parts:

a) det (AB)

\mid AB\mid=\mid A\mid.\mid B\mid\\\\\mid AB\mid=-3\times 2=-6

b) det (B⁵ )

\mid B^5\mid=\mid B\mid ^5=2^5=32

c) det (2A)

Since we know that

\mid kA\mid =k^n\mid A\mid

so, it becomes,

\mid 2A\mid =2^4\mid A\mid=16\times -3=-48

d) \bold{det(A^TA)}

Since we know that

\mid A^T\mid=\mid A\mid

so, it becomes,

\mid A^TA\mid=\mid A^T\mid \times \mid A\mid=-3\times -3=9

e) det (B⁻¹AB)

As we know that

\mid B^{-1}\mid =\mid B\mid

so, it becomes,

\mid B^{-1}AB}\mid =\mid B^{-1}.\mid \mid A\mid.\mid B\mid=2\times -3\times 2=-12

Hence, a) -6, b) 32, c) -48, d) 9, e) -12

OleMash [197]

Answer:

11 /13 = t

Step-by-step explanation:

5/13  = t -6/13

Add 6/13 to each side

5/13 + 6/13  = t -6/13+ 6/13

11 /13 = t

Determine the value of x
Tomtit [17]

Answer:

the answer will be Root 2

Step-by-step explanation:

x^2 = 1^2 + 1^2

We take the unmentioned side as 1 because it is an isosceles triangle and thus 2 of the sides will have the same measure

x^2 = 1 + 1

x^2 = 2

taking square root on both the sides

x = root of 2
