An old coin is sold for $2 and its value increases by 8% each year after it is sold. What is the value of the coin, in dollars,

spayn [35]

Principal=P=$2
Rate of interest=8%=R
Time=T=10years

Interest be I

$\\ \sf\Rrightarrow I=\dfrac{PRT}{100}$

$\\ \sf\Rrightarrow I=\dfrac{2(8)(10)}{100}$

$\\ \sf\Rrightarrow I=\dfrac{280}{100}$

$\\ \sf\Rrightarrow I=2.8\$$

Now

Value of coin after 10years =2+2.8=4.8$

Indicate in standard form the equation of the line passing through the given point and having the given slope

Naddik [55]

ANSWER

The equation is

$y - 5x + 20 = 0$

EXPLANATION

Let the equation be
$y = mx + c$

where
$m = 5$
is the slope of the line.

We substitute this value to obtain,

$y = 5x + c$

Since the line passes through
$(4,0)$
we can use this point to determine the value of c.

We substitute this point to obtain,

$0 = 5(4) + c$

$0 = 20 + c$

$c = - 20$

Our equation now becomes

$y = 5x - 20$

We can write this in standard form as

$y - 5x + 20 = 0$

Write 100,000 as a power of 10. A) 103 B) 104 C) 105 D) 106

mamaluj [8]

A) $10^3$ = 10 * 10 * 10 = 1,000
It is not A

B) $10^4$ = 10 * 10 * 10 * 10 = 10,000
It is not B

C) $10^5$ = 10 * 10 * 10 * 10 * 10 = 100,000
It could be C

D) $10^6$ = 10 * 10 * 10 * 10 * 10 * 10 = 1,000,000
It is not D

Your answer is C) $10^5$

Hope I helped!
