√-324= i√324

324 =2*162

324=2*2*81

324=2*2*9*9

i√324=i√2*2*9*9= i* 2*9= 18i

given the polynomial function below find F(-4) f(x)=2x^ 2 -x + 9

Answers

Answer:

45

Step-by-step explanation:

The value of f(-4) in the polynomial functions f(x) = 2x² - x + 9 is 45

How to evaluate the function?

The function is given as:

f(x) = 2x² - x + 9

Substitute -4 for x

f(-4) = 2(-4)² - (-4) + 9

Evaluate the exponents

f(-4) = 2(16) - (-4) + 9

Evaluate the product

f(-4) = 32 - (-4) + 9

Evaluate the sum and the difference

f(-4) = 45

Hence, the value of f(-4) is 45

A graph shows time (minutes), numbered 2 to 18 on the horizontal axis (t), and altitude in feet, numbered 30 to 270 on the vertical axis (h). A solid circle appears at point (0, 210) and point (14, 0), and a line connects the 2 points.
What is the domain of the function represented in the graph?

{t| 0 ≤ t ≤ 14}
{h| 0 ≤ h ≤ 210}
{t | 0 ≤ t ≤ 210}
{h | 0 ≤ h ≤ 14}

Answers

Answer:

its A

Step-by-step explanation:

Carl wheezer told me

The domain of the function will be {t| 0 ≤ t ≤ 14}. so the correct option is A.

Since we know that the domain of a function refers to the set of possible input values or the values that the independent variable can take.

Thus, the independent variable is represented by the horizontal axis, which is time (t) in minutes.

We are given that the solid circle appears at point (0, 210) and point (14, 0), and a line connects these two points.

The x-coordinate of the first point is 0, and the x-coordinate of the second point is 14. So, the time values that correspond to these points are 0 minutes and 14 minutes, respectively.

We can see that the function is defined from time 0 to time 14.

Therefore, the correct answer is:

{t | 0 ≤ t ≤ 14}

This means that the domain of the function is the set of all possible values of t such that t is greater than or equal to 0 and less than or equal to 14.

Katie ordered candles that cost $3 each from a website. She was charged a flat shipping fee of $6 and no sales tax. If she spent a total of $54, which equation can be used to find c, the number of candles she ordered?

Answers

Answer:

Equation can be used to find  the number of candles (c) Katie ordered is 54 = 3c + 6 .

Option (C) is correct .

Step-by-step explanation:

A. 3c = 54

B. 6c = 54

C. 3c + 6 = 54

D. 3c – 6 = 54

As given

Katie ordered candles that cost $3 each from a website.

She was charged a flat shipping fee of $6 and no sales tax.

If she spent a total of $54,

c represented the number of candles .

Equation becomes

Total cost = Cost per candle + Flat shipping fee

54 =  3 × c + 6

54 = 3c + 6

Equation can be used to find  the number of candles (c) Katie ordered is 54 = 3c + 6 .

Option (C) is correct .
