Answer:

If the x-6 is all under the sqrt, the last answer is right:

6<= x <= infinity

If only x is under the sqrt and - 6 is NOT under the sqrt, then:

0 <= x <= infinity is the correct answer.

Step-by-step explanation:

You can look at the equation and or graph to determine the domain of a function. The domain is all the x's that may go into the equation or all the x's on the graph of the function. Inside of a squareroot symbol the number inside there must be positive. While considering the equation, only x's that keep that inside positive can be used.

For sqrt(x-6), x has to be 6 or bigger.

For sqrt(x) - 6, x has to be 0 or bigger.

Answer

Sal spent 43 minutes jogging per day last week.

Elena spent 45 minutes jogging per day last week.

Step-by-step

Part 1: Find the number of minutes Sal jogged.

1. Find the number of minutes out of the week that were spent jogging.

240 - 25 = 215

Sal spent 215 minutes jogging.

2. Find the number of minutes per day he spent jogging.

215 / 5 = 43

Sal spent 43 minutes jogging per day last week.

Part 2: Find the number of minutes Elena jogged.

1. Find the number of minutes out of the week that were spent jogging.

300 - 15(5) = 300 - 75 = 225

Elena spent 225 minutes jogging.

2. Find the number of minutes per day she spent jogging.

225 / 5 = 45

Elena spent 45 minutes jogging per day last week.

Answer and Step-by-step explanation:

The two statements that are true are statement 1 and statement 4:

- The sum of pi and 0 is irrational.

- The product of \frac{9}{5} and \sqrt{19 } is irrational.

Pi is an irrational number, and the square root of 19 is irrational. That's because these numbers can't be put into a simplified fraction to encompass all the digits it contains.

QUESTÃO 01
Korvikt [17]

Responder:

2³

5⁴

10³

a^6

Explicação passo a passo:

Quando um certo valor é multiplicado repetidamente,

Por exemplo,

a * a * a * a = a⁴ (a multiplicado 4 vezes)

Por isso,

2 x 2 x 2 = 2³

5 x 5 x 5 x 5 = 5⁴

10 x 10 x 10 = 10³

a x a x a x a x a x a = a^6

what TRANSFORMATIONS take place to the parent graph f(x)= log(x) to achieve the graph g(x)=log(-2x-4)+5?
Leona [35]

The -4 will translate the graph of f(x) 4 units to the right.
Then the -2 before the x will stretch it vertically with factor 2, then reflect it in the y -axis.
Finally the + 5 will translate the graph 5 units vertically upwards
