Write a Function rule for the table.

Mathematics
2 answers:
Brut [27]3 years ago
6 0

f(x) = x + 3

when x = 0, f(x) = 3

when x = 1, f(x) = 1 + 3 = 4

when x = 2, f(x) = 2 + 3 = 5

when x = 3, f(x) = 3 + 3 = 6

answer is D

f(x) = x + 3

Answer:

D. f(x)=x+3

Step-by-step explanation:

We have been given a table of values. We are asked to write a function rule for our given table.

We can see from our given table that f(0)=3. This means that the y-intercept of our given function is 3.

We can see that with each increase in x, the value of f(x) increases by 1.

f(1)=4

f(2)=5

5-4=1

This means slope of our given function is 1.

Upon substituting m=1 and b=3 in slope intercept form of equation, we will get:

y=mx+b

f(x)=x+3

Therefore, our required function is f(x)=x+3 and option D is the correct choice.

Element X is a radioactive isotope such that every 30 years, its mass decreases by half. Given that the initial mass of a sample
Lena [83]

Answer:

19.3 years

Step-by-step explanation:

Given that the initial mass of a sample of Element X is 100 grams,

The formula is given as:

N(t) = No × (1/2) ^t/t½

Element X is a radioactive isotope such that every 30 years, its mass decreases by half.

N(t) = Mass after time (t)

No = Initial mass = 100 grams

t½ = Half life = 30 grams

N(t) = 100 × (1/2) ^t/30

How long would it be until the mass of the sample reached 64 grams, to the nearest tenth of a year?

This means we are to find the time

N(t) = 100 × (1/2) ^t/30

N(t) = 64 grams

64 = 100(1/2)^t/30

Divide both sides by 100

64/100 = 100(1/2)^t/30/100

0.64 = (1/2)^t/30

Take the Log of both sides

log 0.64 = log (1/2)^t/30

log 0.64 = t/30(1/2)

t = 19.315685693242 years

Approximately = 19.3 years

Please help i suck at these
vaieri [72.5K]

Answer:

1st Option;

j = 4.5

k = 2

Step-by-step explanation:

Let's solve for "j" first:

=> We know that by the definition of midpoint segment theorem we can say;

3j = 5j - 9

0 = 5j - 3j - 9

0 = 2j - 9

0 + 9 = 2j

9 = 2j

9/2 = j

4.5 = j

=> Now that we have j-value we use the same method to solve for k-value;

6k = k + 10

6k - k = 10

5k = 10

k = 10/5

k = 2

Therefore;

j = 4.5

k = 2

<u>So the first option would be correct!</u>

Hope this helps!
