Given f (x )equals 2 x minus 5 and g (x )equals 5 x squared, first find f plus g, f minus g, fg, and StartFraction f Over g

baherus [9]

Answer:

(f + g)(x) = 5x² + 2x - 5

Domain: All real numbers

(f - g)(x) = -5x² + 2x - 5

Domain: All real numbers

(fg)(x) = 10x³ - 25x²

Domain: All real numbers

(f/g)(x) = $\frac{2x-5}{5x^2}$

Domain: (negative infinity, 0)U(0, positive infinity)

Step-by-step explanation:

For f + g, we are simply adding the 2 together

Domain: All values of x work, as any value x outputs any value y

For f - g, we are simply subtracting the 2 together

Domain: All values of x work, as any value x outputs any value y

For f times g, we are simply multiplying (distributing) the 2 together

Domain: All values of x work, as any value x outputs any value y

For f divided by g, we are simply dividing (fraction) the 2 together

Domain: All values except for 0 work (undefined error), so asymptote at x = 0

Use the diagram to find the following bearings.

Ad libitum [116K]

9514 1404 393

Answer:

(a) 15°

(b) 256°

(c) 133°

(d) 313°

Step-by-step explanation:

We assume your bearings are to be reported as an angle measured clockwise from north.

A) The given angle is the bearing: 15°.

__

B) The bearing can be found by subtracting this angle from 450°:

450° -194° = 256°

__

C) The bearing can be found by adding 90° to the angle shown:

43° +90° = 133°

__

D) The reverse bearing can be found by adding 180°:

133° +180° = 313°

_____

Additional comment

Angles in Cartesian coordinates are conventionally measured counterclockwise from the +x axis. In that sense, the angle of C could be considered to be -43°.

Bearing angles are reported different ways. One of them is as an angle in the range 0–360°, measured clockwise from north (up, or +y axis). As such, it can be found by subtracting the conventional Cartesian angle from 90°.

When the Cartesian angle is more than 90°, 360° must be added to the difference to bring it back into the desired 0–360° range. Essentially, angles greater than 90° must be subtracted from 90° +360° = 450°.

Reverse bearings are found by adding or subtracting 180°.

__

An alternate convention for reporting bearings is as an angle in the range 0–90° east or west from north or south. In this convention, A = N15E, B=S76W, and C=S47E.

Occasionally, you will see the angles B and C reported from east or west: B=W14S; C=E43S. This keeps the angles in the 0–45° range. This is NOT a recommended way to report bearings.

Reverse bearings are found by swapping N/S and E/W. That is, the bearing from A to O is S15W, for example.

Solve for t. t + 19 = 45) it will give u 29 points if u help me!

Oksi-84 [34.3K]

Hi there!

Answer:

t=26

*The answer must have a positive sign.*

Step-by-step explanation:

First, you subtract by 19 from both sides of an equation.

$t+19-19=45-19$

Then, you subtract by the numbers from left too right.

$45-19=26$

Final answer is t=26

I hope this helps you!

Have a nice day! :)
