The zeros of the function are also called the roots. Thus, this problem is basically locating the root of the given equation.

To locate the roots, we equate the equation f(x) to 0.

We then dissect each term to identify a, b, and c in the quadratic equation formula:

x = (- b +- √(b²-4ac))/2a

a = 2
b = 8
c = -3

x1 = 0.3452
x2 = -4.345

Find an antiderivative F(x) with F′(x) = f(x) = 6 + 24x^3 + 18x^5 and F(1)=0.
7nadin3 [17]

Answer:

The antiderivative is F(X) = 6x + 6x^4 + 3x^6 - 15.

Step-by-step explanation:

Antiderivative F(x)

This is the integral of F^{\prime}(x)

So

F′(x) = f(x) = 6 + 24x^3 + 18x^5

Then:

F(x) = \int (6 + 24x^3 + 18x^5) dx

F(x) = 6x + \frac{24x^4}{4} + \frac{18x^6}{6} + K

F(x) = 6x + 6x^4 + 3x^6 + K

F(1)=0

F(X) = 0 when x = 1. We use this to find K.

F(x) = 6x + 6x^4 + 3x^6 + K

0 = 6 + 6 + 3 + K

K = -15

Thus

The antiderivative is F(X) = 6x + 6x^4 + 3x^6 - 15.

Simplify: (25 + 17) – |37 – 13| A. 15 B. 18 C. 20 D. 21
vaieri [72.5K]

First we solve modulus

| 37-13| =|24|= 24

Now solving Bracket

25+17 = 42

Therefore, 42 - 24 = 18

I need help ! It’s says try to analyze it for clues about its purpose and meaning .
Lyrx [107]

Answer:

See explanation

Step-by-step explanation:

The scatter plot shows that there is a negative linear trend.  That as the distance to the coffee shop increases, whatever the y value represents goes down.

6 below and 6 above

(1,4)  (7,1)  Coordinates of the two points on the trend line

I can't see what the Y axis represents so can't really explain the prediction but as the distance to the coffee shop increases, whatever the Y axis represents will decrease.
