Answer: B: (1-5x²)³, all real numbers

Step-by-step explanation:

The notation f\circ g(x) is called function composition, which is where you pass one function in as the value of another function. In other words, \( f\circ g(x)=f(g(x)) \).

Since we have the values for f(x) and g(x), let's plug them in.

f(g(x))\\f(1-5x^2)\\(1-5x^2)^3

Hence, the best answer choice is B, as all real numbers would work and it is the cube of 1 - 5x².

CAN SOMEONE HELP ME !!!!!!!!!
MissTica

Answer:

She will get <u>80mg</u> of dextromethorphan and <u>800mg</u> of guaifenesin. And the bottle last for <u>6 days</u> approximately.

Step-by-step explanation:

Given that the Robitussin DM contains dextromethorphan 10mg/5mL and gualfenesin 100mg/5mL. And we are also given that Mrs Smith took four doses and each dose is 2 teaspoons=2X5=10mL.

So, four doses=4X10=40mL.

So, dextromethorphan in 4 doses is = \frac{10}{5}X40=80mg

And Guaifenesin in 4 doses is = \frac{100}{5}X40=800mg

Dosage of medicine daily she has to take=40mL and the bottle contains 237 mL. Hence the number of days bottle last = \frac{237}{40}=5.925≈6 days approximately.

Solve the quadratic equation x2=25/36.<br><br><br>What are the solutions of the equation x2=25/36?
Alinara [238K]

Answer:

x is equal to positive 5/6 and negative 5/6

Step-by-step explanation:

To solve this, you simply need to take the square root of both sides:

x^2 = \frac{25}{36}\\\sqrt{x^2} = \sqrt{\frac{25}{36}}\\x = \pm \frac{5}{6}

Find the zeros of f(x) = x^2+5x-6.<br> A. {-2,3}<br> B. {-6,1}<br> c. {-2,-3}<br> D. {-6,-1}
Arisa [49]

Answer:

x^2+5x-6

a = 1  b = 5 and c = -6

Using the quadratic formula:

x = [-5 +- sq root (25 -4 * 1 *-6) ] / 2 * 1

x = [-5 +- sq root (49)] / 2

x = [-5 +- 7] / 2

x1 = 1

x2 = -6
