Answer: The answer is (A) y = sinx.

Step-by-step explanation: We are given to select the correct function from the options that has a domain of all real numbers.

We know that only some function and cos function has a domain of all real numbers.

Thus, out of the given options, only the since function has a domain (-\infty,\infty) and range of [-1,1].

The domain of the other three functions are different from some function.

Thus, the correct option is (A) y = sinx.

Use multiples to write two fractions equivalent to 7/9.
Nitella [24]

Answer:

\frac{14}{18} , \frac{21}{27}

Step-by-step explanation:

To create equivalent fractions multiply the numerator and denominator of the fraction by the same multiples.

Using a multiple of 2, then

\frac{7}{9} = \frac{7(2)}{9(2)} = \frac{14}{18}

Using a multiple of 3, then

\frac{7}{9} = \frac{7(3)}{9(3)} = \frac{21}{27}

Pls help if you can Thx!

GIVEN:

Cost of a taco and a cup of tea = $2.10

  • x + y = 2.10 ...(1)

Cost of 2 tacos and 3 cup of tea = $5.15

  • 2x + 3y = 5.15 ...(2)

ANSWER:

On solving eq(1), we get

  • x = 2.10 – y

Substitute the value of x in eq(2), we get

  • 2(2.10 – y) + 3y = 5.15
  • 4.20 – 2y + 3y = 5.15
  • y = 5.15 – 4.20
  • y = 0.95

So, x = 2.10 – 0.95

  • x = 1.15

Hence, Cost of a taco is $1.15

So, <u>Correct choice</u> - [E] $1.15
