Growth means a base for exponentiation bigger than 1 (in absolute value), otherwise it's decay.

Only the first choice has a base biggerthan 1. The last choice is equivalent to $f(x)=5 ( \frac 1 6)^x$ so has a base less than 1.

Answer: A

Note how answer A has the form (constant)(constant greater than 1)^exponent. This is how you recognize expo growth. The other 3 answer choices are disqualified because their bases {0.11, 1/2, 1/6} are fractions between 0 and 1.

The correct answer is A.

Answer:

basketball= 66.66 infinite%

baseball=42.86%

Step-by-step explanation:

if you divide 14 by 21 you get .66 infinite which is 66.66 infinite%

divide 9 by 21 you get around .4286 which is 42.86%

Hezekiel runs 1000 m at a rateof 3 minutes per km. how long does he take to run 500 m

lana66690 [7]

Step-by-step explanation:

1 km = 1000 m

(hence the term "kilo" which means 1000).

so. he runs 1000 m at the rate of 3 minutes per km, that means 3 minutes per 1000 m.

now, we can see the solution already with our eyes.

but let's do it formally :

the rate or ratio between time and distance must be the same for the same speed.

so,

3 min / 1000 m = x min / 500 m

500 m × 3 min / 1000 m = x min

1/2 × 3 min = x min

3/2 = 1.5 min = x min

so, it takes him 1.5 minutes (90 seconds) to run 500 m.

dalvyx [7]

Answer:

(a)|MA|, |MB| and |MC|

(b) |BD|

Step-by-step explanation:

An adapted diagram of this question is attached. You can vary the labelled letters as required.

Definition

A radius is a line drawn from the center of a circle to its circumference.
A segment is a line that connects two points.
A diameter is a chord which passes through the center of the circle.
A chord is any line joining two points on the circles' circumference.

By these definitions:

(a)Segments that are radii of this circle.

We have: |MA|, |MB| and |MC|

(b)Segment that is a diameter of this circle.

|BD|

(c)A chord of this circle that is not a diameter.

|BC|
