Answer:

Enoch is 30
Martin is 15

Step-by-step explanation:

The difference in ages remains the same over time. Enoch, at twice Martin's age, is still 15 years older. That means Martin is 15 and Enoch is 30.

If I observe a bed of mussels on the coast of California in which five species live where the abundances of each species are 100

babymother [125]

Answer:

The Probability of randomly picking the third species=0.316

Step-by-step explanation:

In a bed of mussels on the coast of California in which five species live,

The Abundance of each Species are 100, 500, 998, 12, and 1548

Total Value=100+500+998+12+1548=3158

Abundance of third Species=998

Probability $=\frac{Abundance of Selected Species}{Total Abundance}$

Probability (randomly picking the third species) $=\frac{998}{3158}$ = $\frac{499}{1579}$ =0.316

A small company's net income for the first six months of the year was 76,500 for the last six months it was 100,000 what is the

Stells [14]

Answer:

The ratio of net income in the first 6 months, to the last six months is $76,500 / $100,000. This simplifies intuitively as follows:

76500/100000

Dividing by 100: 765/1000

Dividing by 5: 153/200

The denominator 200 is only divisible by the prime numbers 2 and 5, and since the numerator 153 is not divisible by either 2 or 5, this means that this is in simplest form, and the final answer is 153/200.

Eduardo bought 2-liter sports drink for soccer practice.During practice,Eduardo drank 250 millimeters of the sports drink.Then h

adelina 88 [10]

Answer:

1,250 millileters

Step-by-step explanation:

The computation of the number of milliters of the sports drink left is shown below:

Given that

The 2-liter sports drink is purchased

And, drank 250 millimeters and than drank one-half liter of the drink

Now convert liter to millileter

1 litre = 1000 milliliter.

2 liters = 2 × 1000 milliliters.

= 2000 milliliters.

Now the left drink would be

= (2000 - 250) - (250 × 2)

= 1,750 - 500

= 1,250 millileters

Which conclusion about f(x) and g(x) can be drawn from the table

NeTakaya

<h2>Answer:</h2>

The conclusion that is true about f(x) and g(x) based on the table of values is:

The function f(x) and g(x) are reflections over the y-axis.

<h2>Step-by-step explanation:</h2>

We know that the rule that describes the reflection over the y-axis is:

(x,y) → (-x,y)

Hence, if we have a function f(x) as:

$f(x)=2^x$

Then it's reflection over the y-axis is:

$f(-x)=2^{-x}\\\\\\f(-x)=(2^{-1})^x\\\\\\f(-x)=(\dfrac{1}{2})^x\\\\i.e.\\\\\\g(x)=(\dfrac{1}{2})^x$

Hence, they are reflection over the y-axis.

Also, we know that the exponential function of the type:

$y=ab^x$

where a>0 is a increasing function if b>1

and is a decreasing function if: 0<b<1

Hence, f(x) is a increasing function and g(x) is a decreasing function.

Also, the initial value of a function is the value of function when x=0

when x=0 we see that both f(x)=g(x)=1

i.e. Both f(x) and g(x) have same initial value.

Also,by the graph we may see the relation.
