There are 60 minutes in 1 hr, so in 1 hour, her heart beats 65(60)
24 hours in 1 day, so it beats in 1 day 24(65 * 60)
365 days in 1 year, so it beats in 1 year, 365(24 * 65 * 60)
how much will it be in 10 years then? 10(365 * 24 * 65 * 60).
Answer:A function transformation takes whatever is the basic function f (x) and then "transforms" it (or "translates" it), which is a fancy way of saying that you change the formula a bit and thereby move the graph around. Moving the function down works the same way; f (x) – b is f (x) moved down b units.

Answer:
420 cm²
Step-by-step explanation:
Given the width is x then the length is x + 8 ( 8 longer than width )
Given the perimeter = 90 cm
Sum the lengths of the sides stating at the top left corner and going clockwise
Noting that the indentation small part is 8 - x
x + 8 + x + x + 8 - x + 8 + x + x + 8 + x + x + 8 - x + 8 + x
= 6x + 48
Equating perimeters
6x + 48 = 90 ( subtract 48 from both sides )
6x = 42 ( divide both sides by 6 )
x = 7
Thus width = 7 cm and length = 7 + 8 = 15 cm
The figure is made of 4 rectangles, thus
area = 4 × (7 × 15) = 4 ×105 = 420 cm²
Hi !
|-9| represents the module of the number -9 or the absolute value of this number.
We know that every module is positive, so |-9| = 9
Here's the general formula :
|x| = x for x>0
|x| = -x for x<0
