Answer: pretty sure it's the number you multiply by 4 is 17

Step-by-step explanation:

when you multiply 4 and 16 you'll get 64 then you subtract 19 and get 45 which is less than 47 so by reasoning if you were to multiply 4 and 17 you'll get 68 then you subtract 19 from 68 and you should get 49 ( you didn't include how much greater than 47 the number should be but the safest bet would be to use 17)

The graph y=f(x) is graphed below. What is the end behavior of f(x)?

Answers

Answer:

as x → -∞, y → ∞ and as x → ∞, y → -∞

Step-by-step explanation:

Just check the first quadrant of the given graph.

In the first quadrant, when x gets smaller, the value of y is increasing to positive infinity.

In other words, as x → -∞, y → ∞

Now, observe the behavior of the graph in the 4th quadrant.

In the 4th quadrant, when x gets larger, the value of y is decreasing to negative infinity.

In other words, as x → ∞, y → -∞

Therefore, the behavior of f(x):

as x → -∞, y → ∞ and as x → ∞, y → -∞

Therefore, option (C) is true.

The end behavior of a graph is defined as what is going on at the ends of each graph when the function approaches positive or negative infinity.

End behaviour of given graph is, x⇒ -∞ then y⇒∞ and x ⇒∞ then y⇒ -∞

Since, here a graph is attached.

From graph it is observed that, when x tends to negative side, graph is going to upward direction. and when x tends to positive side then graph is going to downward direction.

So, when x tends negative infinity then y tends to positive infinity.

when x tends to positive infinity then y tends to negative infinity.

Therefore, end behaviour of given graph are,

x⇒ -∞ then y⇒∞ and x ⇒∞ then y⇒ -∞

Solve the equation.
x² + 6x+15=0

Answers

Answer:

x = -3 + i√6 and x = -3 - i√6

Step-by-step explanation:

Let's apply the "completing the square" method to find the roots of this equation.

Take half of the coefficient 6 of x, square it and add this result to x^2 + 6x. Then subtract the same quantity:

x^2 + 6x + 15 becomes

x^2 + 6x + 3^2 - 3^2 + 15 = 0

Rewriting the first three terms as the square of a binomial, we ge:

(x + 3)^2 - 9 + 15 = 0, which simplifies to:

(x + 3)^2 + 6 = 0, or (x + 3)^2 = -6

Taking the square root of both sides:

x + 3 = ±i√6

Then the two roots are complex:

x = -3 + i√6 and x = -3 - i√6

162 divided by 4.1 estimate

Answers

Answer:

Step-by-step explanation:

162/4.1= 39.51 round to 40

The solution of the equation after dividing would be 40.

Used the concept of the divide that states,

The division method is used to distribute a group of things into equal parts. The division is just the opposite of multiplications.

Given that,

162 divided by 4.1

Now divide the numbers,

162 divided by 4.1

It can be written as,

162 ÷ 4.1

162 / 4.1

1620/41

This gives,

39.512

Rounded to whole numbers,

Therefore, the solution is 40.
