Answer:

(f - g)(x) = x² - 3x - 70

General Formulas and Concepts:

Algebra I

Combining Like Terms

Step-by-step explanation:

Step 1: Define

f(x) = x² - 2x - 63

g(x) = x + 7

(f - g)(x) is f(x) - g(x)

Step 2: Find (f - g)(x)

Substitute: (f - g)(x) = x² - 2x - 63 - (x + 7)
Distribute -1: (f - g)(x) = x² - 2x - 63 - x - 7
Combine like terms (x): (f - g)(x) = x² - 3x - 63 - 7
Combine like terms (Z): (f - g)(x) = x² - 3x - 70

What do calculators use to show scientific notation

Answer:

Basically, when a scientific calculator displays a number as aEb, it means to move the decimal point in a as follows:

If b is positive, move the decimal point b units to the right.

If b is negative, move the decimal point b units to the left.

A ship leaves port at noon and has a bearing of S29oW. The ship sails at 20 knots. How many nautical miles south and how many na

ira [324]

Answer:

Approximately $58.2\; \text{nautical miles}$ (assuming that the bearing is ${\rm S$29^{\circ}$W}$ .)

Step-by-step explanation:

Let $v$ denote the speed of the ship, and let $t$ denote the duration of the trip. The magnitude of the displacement of this ship would be $v\, t$ .

Refer to the diagram attached. The direction ${\rm S$29^{\circ}$W}$ means $29^{\circ}$ west of south. Thus, start with the south direction and turn towards west (clockwise) by $29^{\circ}$ to find the direction of the displacement of the ship.

The hypothenuse of the right triangle in this diagram represents the displacement of the ship, with a length of $v\, t$ . The dashed horizontal line segment represents the distance that the ship has travelled to the west (which this question is asking for.) The angle opposite to that line segment is exactly $29^{\circ}$ .

Since the hypotenuse is of length $v\, t$ , the dashed line segment opposite to the $\theta = 29^{\circ}$ vertex would have a length of:

$\begin{aligned}& \text{opposite (to $\theta$)} \\ =\; & \text{hypotenuse} \times \frac{\text{opposite (to $\theta$)}}{\text{hypotenuse}} \\ =\; & \text{hypotenuse} \times \sin (\theta) \\ =\; & v\, t \, \sin(\theta) \\ =\; & v\, t\, \sin(29^{\circ})\end{aligned}$ .

Substitute in $\begin{aligned} v &= 20\; \frac{\text{nautical mile}}{\text{hour}}\end{aligned}$ and $t = 6\; \text{hour}$ :

$\begin{aligned} & v\, t\, \sin(29^{\circ}) \\ =\; & 20\; \frac{\text{nautical mile}}{\text{hour}} \times 6\; \text{hour} \times \sin(29^{\circ}) \\ \approx\; & 58.2\; \text{nautical mile}\end{aligned}$ .

Can someone please help me with this question?

D. One reason, The others questions don't add up. Reason being, the perimeter of the garden is 4x+60, all of the other questions don't make up for that answer.
(I also can't read D, so I'm just assuming now.)

Twice a number and 5 more is 100

8090 [49]

Hello there! Thank you for asking your question here at Brainly! I will be assisting you with answering this question today, and will be teaching you how to handle it on your own in the future.

First, let's take a look at our problem.
"Twice a number and 5 more is 100."
Based on this context, we are looking for a specific number to plug in.

To solve for this, I will rewrite the problem. As I do so, I will be writing (in parenthesis) the translation of an equation.

Twice a number (2x) and 5 more (+5) is 100 (=100).

Let's rewrite everything that's in parenthesis.
2x + 5 = 100

This is our equation.
To solve for this, we will need to do some basic algebra. Of course, I will teach you how to handle this on your own in future scenarios.

2x + 5 = 100
To solve for x, we need to isolate 2x, and then divide both sides by 2.

2x + 5 = 100
Subtract 5 from both sides to isolate 2x.
5 - 5 = 0
100 - 5 = 95

We now have the following equation:
2x = 95
Divide both sides by 2 to solve for x.

2x / 2 = x
95 / 2 = 47.5

x = 47.5

47.5 is your number.

I hope this helps!
