It has an infinite rotation symmetry because no matter how you rotate the object, it look the same.

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

Solve the equation ?

Morgarella [4.7K]

6m+1=-23. Do the inverse operation of adding 1 which is to subtract 1 to both sides =====> 6m+1-1= -23-1

You divide by 6 both sides
6m/6=-24/6

m= -4

A one day trip to new york, mary spent $6.25 for breakfast and 8.95 for lunch. She can spend no more than an average of $8.50. H

Mary spent $10.30 on dinner to stay in budget.

Step-by-step explanation:

Amount spent on breakfast = $6.25

Amount spent on lunch = $8.95

Amount spent on dinner = x

Average = $8.50

Average = $\frac{Sum\ of\ values}{No.\ of\ values}$
