Mr. Mole left his burrow that lies below the ground and started digging his way at a constant rate deeper into the ground.

Marizza181 [45]

Answer:

$A(t)=-1.8t-4.5$

Step-by-step explanation:

Mr.Mole's digging can be described by a linear model of general equation:

$A(t)=m*t+c$

Where "m" is the rate at which he descends. Note that since the function A(t) measure his altitude relative to the ground, the rate "m" must be negative.

$(m=-1.8)$

$A(t)=-1.8*t+c$

The constant "c" is his starting position. To find this value, assign the given data at t = 5 min to the equation above

$-13.5=-1.8*5+c\\c=-4.5m$

Therefore, the function A(t) is described by the following formula:
$A(t)=-1.8t-4.5$

What is the answer to this problem<br> 8x-2=-9+7×

Ksenya-84 [330]

8x−2=−9+7x

Simplify:

8x−2=−9+7x

8x+−2=−9+7x

8x−2=7x−9

Subtract 7x from both sides.

8x−2−7x=7x−9−7x

x−2=−9

Add 2 to both sides.

x−2+2=−9+2

x=−7

<h3><u>48 people</u> is the right answer.</h3>

Step-by-step explanation:

Let the number of male and female be 3x and 5x

There are twelve more females than males

According to the above problem,

$5x - 3x=12\\ 2x = 12\\ x = \frac{12}{2} \\ \boxed{x = 6}$
