Step-by-step procedure to simplify a square root on a calculator:

In order to take square root for a number, we must first press the secondary functional key on the calculator.

After that we must press " [ √ ] " symbol on the calculator.

"√" = radical symbol key which helps in taking square root for a number.

Now after pressing the square root symbol, enter the number for which you want to find square root for and then finally press enter.

Now the simplified square root value of the respective number can be obtained.

Given a triangle ABC such that AB = 4. AC = squareroot (41) and BC = 5.

Vsevolod [243]

Answer:

A = 51.3°, B = 90°, C = 38.7°

Step-by-step explanation:

The given lengths satisfy the Pythagorean theorem:

(√41)² = 4² +5² ⇒ 41 = 16 +25

so we know the triangle is a right triangle. The right angle is opposite the longest side, so is angle B, opposite side AC.

The remaining angles can be found using trig functions. For example, we know ...

tan(A) = BC/AB = 5/4

A = arctan(5/4) ≈ 51.3°

Then the other acute angle is ...

C = 90° -51.3° = 38.7°

Angles A, B, C are ...

(A, B, C) = (51.3°, 90°, 38.7°)

Find the explicit formula that produces the given sequence. <br> 3/2, 3/4, 3/8, 3/16,...

lara [203]

$\frac{3}{2};\ \frac{3}{4};\ \frac{3}{8};\ \frac{3}{16};\ ...\\\\a_1=\frac{3}{2}\\\\a_2=\frac{3}{4}=\frac{3}{2}\cdot\frac{1}{2}\\\\a_3=\frac{3}{8}=\frac{3}{4}\cdot\frac{1}{2}=\frac{3}{2}\cdot\left(\frac{1}{2}\right)^2\\\\a_4=\frac{3}{16}=\frac{3}{8}\cdot\frac{1}{2}=\frac{3}{2}\cdot\left(\frac{1}{2}\right)^3\\\vdots$
$a_n=\frac{3}{2}\cdot\left(\frac{1}{2}\right)^{n-1}=\frac{3}{2}\cdot\left(\frac{1}{2}\right)^{-1}\cdot\left(\frac{1}{2}\right)^n=\frac{3}{2}\cdot2\cdot\left(\frac{1}{2}\right)^n=3\cdot\left(\frac{1}{2}\right)^n$
