Answer:

Step-by-step explanation:

The order of the top three are

Silver
Copper
Gold

In that order. Copper is used where there is some tolerance for corrosion for it much cheaper than the other two. Gold is used where corosion is a consideration because Gold does not tarnish. Silver is used when conductivity is the primary concern.

Aluminum was tried in house wiring. It is very brittle. I think it was abandoned.

Answer:

Pure silver is best conductor of electricity.

Step-by-step explanation:

Conductivity is the property of materials to which extent a material allows electric current to flow through it.

Metals is defined as the substance which is good conductor of heat and electricity.

Given are list of highly conductive metals,

Pure silver

Pure copper

Pure gold

Aluminium

The presence of free electrons determines a metal’s conductivity.

Silver and copper are metals with single, free-moving electrons.

Pure silver is the most conductive metal of all metals

Find the smallest number by which the following numbers should be multiplied to obtain a perfect cube. (a) 3087 (b) 2560

Daniel [21]

Check each number's prime factorization, then add any factors necessary to make each one a cube.

(a) 3

$3087 = 3^2 \times 7^3 \implies \boxed{3}\times3087 = (3\times7)^3 \implies 9261=21^3$

(b) 25

$2560 = 2^9\times5^1 \implies \boxed{5^2}\times2560 = \left(2^3\times5\right)^3 \implies 64000 = 40^3$

The function f(x) = -x2 - 4x + 5 is shown on the graph. Which statement about the function is true? V 14 2 (-2.9) 10 8+ O The do

ikadub [295]

Answer:

we have

using a graph tool

see the attached figure

the domain of the function is all real numbers------> the interval is (-∞,∞)

the range of the function is --------------------------------> the interval (-∞,9]

therefore

the answer is

The range of the function is all real numbers less than or equal to 9

suppose 7,330 dollars is invested at 14.8% per annum for 10 years compounded monthly, how many dollars will be earned in interes

s2008m [1.1K]

Answer:

$24,580.12

Step-by-step explanation:

Lets use the compound interest formula to solve:

$A=P(1+\frac{r}{n} )^{nt}$

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

First, change 14.8% into a decimal:

14.8% -> $\frac{14.8}{100}$ -> 0.148

Since the interest is compounded monthly, we will use 12 for n. Lets plug in the values now:

$A=7,330(1+\frac{0.148}{12})^{12(10)}$

$A=31,910.12$

Now subtract that number from our original amount invested:

$31,910.12-7,330=24,580.12$

The dollars earned in interest is $24,580.12
