${\qquad\qquad\huge\underline{{\sf Answer}}}$

Here we go ~

$\qquad \sf \dashrightarrow \: scale \: \: factor = \cfrac{new \: \: measure}{original \: measure}$

$\qquad \sf \dashrightarrow \: s = \dfrac{6}{2}$

$\qquad \sf \dashrightarrow \: s = 3$

so, correct choice is D

Question 19

atroni [7]

Answer:

When Jon determined A(12), it means he must have found the amount in the account after 12 years. i.e. the amount when t = 12 years.

Hence, option (A) is true.

Step-by-step explanation:

BACKGROUND KNOWLEDGE ABOUT EXPONENTIAL GROWTH

We know that an exponential increase in Math can be termed as the rapid increase of an amount by percentage over a certain period of time.

It can be expressed using the formula

y = a (1+b)ˣ

here

y represents the final amount

a represents the original amount

b represents the growth factor

x represents the time that has passed

Now, let is us map our problem because it indicates the same concept.

SOLVING THE QUESTION

Given the function

$A\left(t\right)=2000\left(1+0.0412\right)^{12t}$

Here

A(t) represents the final amount

2000 represents the original amount

0.0412 represents the growth rate

t represents the number of years

Thus,

When Jon determined A(12), it means he must have found the amount in the account after 12 years. i.e. the amount when t = 12 years.

Hence, option (A) is true.

Rectangular classroom seats 72 students. If the seats were rearragned with 3 more seats rows in each row, the classroom would ha

Gre4nikov [31]

Let the original number of seats in a row be x;
Let the number rows be y;

( x + 3) * (y - 2 )= 72 and x * y = 72 => 72 + 3 * y - 2 * x = 72 => 3 * y = 2 * x;
=> x is divisible by 3;

1. x = 3 => y = 72 / 3 => y = 24;
2. x = 6 => y = 72 / 6 => y = 12;
3. x = 9 => y = 72 / 9 => y = 8;
4. x = 12 => y = 72 / 12 =. y = 6;
5. x = 24 =. y = 72 / 24 => y = 3;
6. x = 36 => y = 72 / 36 => y = 2;
7. x = 72 => y = 72 / 72 => y = 1;

My analysis tell me that the right answer is 9 seats in a row and 8 rows;
The original number in each row is 9.

Would the -5 go to the left or the right on the number scale?

jeyben [28]

The number -5 would go to the left of a number scale. Typically because all negatives move to the left of zero on the number scale.
