Let “a” represent Andrew’s age TODAY. Write an expression to represent the situation. Five years less than four times Andrew’s a

EleoNora [17]

Answer:

$y = 4a - 5$

Step-by-step explanation:

Let y represent the given situation.

Given:

Andrew's age = a

We need to find the expression for given abatement.

Solution:

The given statement: Five years less than four times Andrew’s age

Five years less than four times Andrew’s age = $4\times (Andrew's\ age) - 5$

Andrew's age is known, so we substitute Andrew's age = a

$y = 4\times (a) - 5$

$y = 4a - 5$

Therefore, the expression for the given situation $y = 4a - 5$

Two 1.60cm×1.60cm plates that form a parallel-plate capacitor are charged to ± 0.711nC . What is the potential difference across

lina2011 [118]

The surface charge density:
S(igma) = Q / A
A = 1.6 * 10^(-2) * 1.6 * 10^(-2) = 2.56 * 10^(-4) m²
The electric field: E = S / E(psilon) o
E = 0.711 * 10^^(-9) / ( 2.56 * 10 ^(-4) * 8.85 * 10 ^(-12) ) =
= 0.3138 * 10 ^6 = 3.138 * 10^5 V/m
a ) Δ V = E d
Δ V = 3.138 * 10^5 V/m* 1.2 * 10^(-3) m = 376.56 V
b ) When d = 2.40 mm:
Δ V = 3.138 * 10^5 V/m * 2.40 *10^(-3) m = 753.12 V

Scientific notation uses expression which gives easy access of order. The scientific notation of given number is: Option A: 1.6E-8

<h3>How to convert a number to scientific notation?</h3>

It is usually of the form $a.bc.. \times 10^k$ exponent of 10 starts)

(we have 1 ≤ |a| < 10 ) (where |a| is magnitude of a without sign)

This notation is used to get some idea of how large or small a number is in terms of power of 10.

<h3>What are some basic properties of exponentiation?</h3>

If we have $a^b$ then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).

Exponentiation(the process of raising some number to some power) have some basic rules as:

$a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\ a^b \times a^c = a^{b+c}$

The given number is converted in scientific notation as:

$0. 000000016 = \dfrac{1.6}{100000000} = \dfrac{1.6}{10^8} = 1.6 \times 10^{-8} = 1.6 E -8$

Thus, the scientific notation of given number is: Option A: 1.6E-8
