PLEASE HELP ASAP, PUT INTO NORMAL NUMBERS, STANDARD FORM?

Answers

Answer 1

Given:

The numbers are written in scientific notation.

To find:

The standard form of given numbers.

Solution:

Formula used:

[tex]a^{-n}=\dfrac{1}{a^n}[/tex]

(a)

[tex]7.2\times 10^{-8}=7.2\times \dfrac{1}{10^8}[/tex]

[tex]7.2\times 10^{-8}=\dfrac{7.2}{1000000000}[/tex]

[tex]7.2\times 10^{-8}=0.000000072[/tex]

(b)

[tex]6.3\times 10^{-9}=6.3\times \dfrac{1}{10^9}[/tex]

[tex]6.3\times 10^{-9}=\dfrac{6.3}{10000000000}[/tex]

[tex]6.3\times 10^{-9}=0.0000000063[/tex]

(c)

[tex]4.54\times 10^{-5}=4.54\times \dfrac{1}{10^5}[/tex]

[tex]4.54\times 10^{-5}=\dfrac{4.54}{100000}[/tex]

[tex]4.54\times 10^{-5}=0.0000454[/tex]

(d)

[tex]7.041\times 10^{-10}=7.041\times \dfrac{1}{10^{10}}[/tex]

[tex]7.041\times 10^{-10}=\dfrac{7.041}{100000000000}[/tex]

[tex]7.041\times 10^{-10}=0.0000000007041[/tex]

Therefore, [tex]7.2\times 10^{-8}=0.000000072, 6.3\times 10^{-9}=0.0000000063, 4.54\times 10^{-5}=0.0000454,[/tex]

[tex]7.041\times 10^{-10}=0.0000000007041[/tex].

arcsin0=? arccos0=? arctan1=?​

Answers

Answer:

arcsin0= 0 degrees

arccos0= 90degrees

arctan1= 45 degrees

Step-by-step explanation:

To get arcsin0, let the unknown value be x

sin x = 0

Take arcsin of both sides

arcsin(sinx) = arcsin 0

x = arcsin0

x = 0 degrees

Hence arcsin0 = 0degrees

For cos x = 0

Take arccos of both sides

arccos(cosx) = arccos 0

x = arcscos0

x = 90 degrees

Hence arccos0 = 90degrees

For tan x = 1

Take arctan of both sides

arctan(tanx) = arctan 1

x = arctan1

x = 45 degrees

Hence arctan1 = 45degrees

The measure of Angle 1 is 35º and it is complementary to Angle 2. The
measure of Angle 2 is 5x. What is the value of x?

Answers

Answer:

x = 11

Step-by-step explanation:

35 + 5x = 90    {Complementary angles}

Subtract 35 from both sides

   5x = 90 - 35

  5x = 55            {Divide both sides by 5}

    x = 55/5

    x = 11

Answers

Answer:

105°

Step-by-step explanation:

An angle is created by West First Street and South Main Street. Call this angle <1. m<1 = x, an unknown.

An angle is created by West First Street and North Main Street. Call this angle <2. This angle measures 30° less than <1, so it measures x - 30.

The two angles form a linear pair, so they are supplementary.

The sum of the measures of supplementary angles is 180 deg.

x + x - 30 = 180

2x - 30 = 180

2x = 210

x = 105

m<1 = 105

The angle we are looking for, created by North Main Street and East First Street is vertical to angle 1, so it is congruent to angle 1.

Answer: 105°

Solve the equation: 12(x + 8) = 11x - 5 What is the solution?

Answers

Answer:

We conclude that the solution is:

[tex]x = -101[/tex]

Step-by-step explanation:

Given the equation

[tex]12\left(x\:+\:8\right)\:=\:11x\:-\:5[/tex]

Expand 12(x + 8):  12x + 96

[tex]12x+96=11x-5[/tex]

Subtract 96 from both sides

[tex]12x+96-96=11x-5-96[/tex]

Simplify

[tex]12x=11x-101[/tex]

Subtract 11x from both sides

[tex]12x-11x=11x-101-11x[/tex]

Simplify

[tex]x=-101[/tex]

Therefore, we conclude that the solution is:

[tex]x = -101[/tex]
