if a domain is "all real numbers" can it be a function?

Answers

Answer 1

Hello!

Answer:

Yes

Step-by-step explanation:

Functions assign outputs to inputs. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.

Hope this helps!

Answer 2

Answer:

Yeah

Step-by-step explanation:

you know real numbers are the combination of. the rational and irrational number so they domain over all other functions

For given question,

Jamal wants to find the length of 'd'

For right triangle in the figure, 'd' is the hypotenuse.

Jamal should find the other two sides of the triangle.

And then using Pythagoras theorem, Jamal can find the length of 'd'

So, Jamal need to find the length of each leg by subtracting x coordinate and y coordinate.

Therefore, Jamal's next step is : Jamal should find the length of each leg by subtracting x coordinate and y coordinate

A bird was sitting 8 meters from the base of an oak tree. It then flew in a straight line 9 meters to reach the top of the tree.
How tall is the tree?
The tree is
meters tall.
Note: Round your answer to the nearest hundredth.

Answers

Answer:

wouldn't it be 17 meters?

Answer:  4.12

=========================================================

Explanation:

Draw a right triangle. The horizontal leg is 8 meters. The hypotenuse is 9 meters. The vertical height is unknown, so we'll call it x.

Apply the pythagorean theorem to solve for x

[tex]a^2 + b^2 = c^2\\\\8^2 + x^2 = 9^2\\\\64 + x^2 = 81\\\\x^2 = 81-64\\\\x^2 = 17\\\\x = \sqrt{17}\\\\x \approx 4.1231056\\\\x \approx 4.12\\\\[/tex]

The tree is approximately 4.12 meters tall

Plz help this is for a grade‼️ the ratio of males to females in the middle school is 6:8. If there are 126 make students,how many female students are there?​​

Answers

Answer:

168 girls

Step-by-step explanation:

126 boys and 168 girls.

Answer:

The answer should be 168 female students.

Step-by-step explanation:

Since the ratio of males to females is 6:8 and there's 126 male students, by dividing 126 by 6 you can get 21 then using that 21 you can multiply it by 8 to find how many female students there are which is 168 and dividing 126:168 by 21 you can get 6:8.

126 divided by 21=6

168 divided by 21=8

A function f(x) = x^2 - 4 has a domain as the set of integers
of from 1 through 10, inclusive (including 1 and 10). For
how many values of x is f(x) positive?

Answers

Answer:

8

Step-by-step explanation:

f(x) = (x+2)(x-2)

Substituting x=1 into f(x):

f(1) = 3*-1

     = -3

Since -2 & 2 touch the x-axis, 1 has a negative y value, 2 has a y value of 0, and all values from 2, are positive.

Hence,

3, 4, 5, 6, 7, 8, 9, 10 are all positive. Therefore, the answer is 8

This can be confirmed with a graph, as attached below.

Paul mixes nuts worth $1.40 per pound with oats worth $1.70 per pound to get 30 pounds of trail mix worth $1.50 per pound. How many pounds of nuts and how many pounds of oats did he use?

Paul used pounds of nuts and pounds of oats.

Answers

The quantity of pounds of nuts and oats used by Paul is 20 and 10 pounds respectively.

According to the question:

Let pounds of nuts used = x Let pounds of oats used = y

Total quantity of trail mix used = 30 pounds and Overall cost of trail mix = 30 × 1.50 = $45.

The information above can be used to generate two equations as follows;

1.4x + 1.7y = 45.............eqn(1)x + y = 30.......................eqn(2)

Consequently, by solving the equations simultaneously; we have;

Pounds of nuts, x = 20 pounds.

Pounds of oats, y = 10 pounds.
