In which number does the digit 4 have a value that is \dfrac{1}{10} 10 1 start fraction, 1, divided by, 10, end fraction times

MrRissso [65]

Answer:

The digit 4 should be in the thousand position in the number sought;

Examples

9.304,

9.004

Step-by-step explanation:

Here, we are required to consider decimal places of numbers

The digit 4 in the number 3.8463 is in the hundredth position

That is 0.04

We are asked to look for the number with a digit 4 that has the same value as $\frac{1}{10} \times$ the digit 4 in 3.8463

That is

$\frac{1}{10} \times 0.04 = 0.004$

Therefore, the digit 4 in the number sought should be in the thousandth position, that is 0.004

Example includes 9.304 or 9.004.

zloy xaker [14]

Answer:

The ordered pair is $(-2,3)$

Step-by-step explanation:

$y=x+5\\y=-2x-1\\\implies x+5=-2x-1\\\implies 3x=-6\\\boxed{x=-2}\\\implies y=-2+5=\boxed {3}\\$

The annual interest rate on a $10,000 loan is 18%. The exponential function that represents this is y = 10000(1.18t). Write the

Yuki888 [10]

Answer:

$y=10000(1.015)^{12t}$

option-B......Answer

Step-by-step explanation:

We are given

amount taken for loan =$10000

so, P=10000

annual interest rate =18%

r=0.18

now, we can use formula

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

Since, it is compounded monthly

so, n=12

we can plug values

$y=10000(1+\frac{0.18}{12} )^{12t}$

$y=10000(1.015)^{12t}$
