Examples of Rational Functions

The function R(x) = (x^2 + 4x - 1) / (3x^2 - 9x + 2) is a rational function since the numerator, x^2 + 4x - 1, is a polynomial and the denominator, 3x^2 - 9x + 2 is also a polynomial.

You’re making 40 servings of English custard. Each serving is 250 ml. The following recipe yields 2 L.

Airida [17]

Answer:

Milk 10 L

Vanilla essence = 20 ml

Sugar = 1kg

Egg yolks 100 yolks

Step-by-step explanation:

2l/250ml = 8 servings per recipe ,

40 servings/8 = 5 "batches"

Milk 2 L * 5 = 10 L

Vanilla essence 4 ml * 5 = 20 ml

Sugar 200 g * 5 = 1000g = 1kg

Egg yolks 20 * 5 = 100 yolks

Earth has been charted with vertical and horizontal lines so that points can be named with coordinates. The horizontal lines are

Komok [63]

Refer to the figure shown below.

r = 6400 km, the radius of the earth

Part a.
The circumference of the great circle is
2πr = 2π*(6400 km)
= 40212.4 km
Answer: 40212.4 km

Part b.
At a latitude with angle x = θ, the circumference2 of the latitude circle is
2π(r cos x) = 2π*(6400 cos(x)
= 40212.4 cos(x)
Note that the angle x is in radians.
Answer: The circumference is 40212.4 cos(x) km

Part c.
If a latitude circle has a circumference of about 3593 kilometers, then
40212.4 cos(x) = 3593
cos(x) = 3593/40212.4 = 0.0894
x = arcos(0.0894) = 84.9°
Answer: The latitude circle is at an angle of about 85°.

Part d.
The equator has latitude angle of 0°.
The circumference of the equator is
40212.4*cos(0°) = 40212.4 km
Answer: 40212.4 km

Can someone help me out

12345 [234]

Answer:

g - 16 is the answer

Step-by-step explanation:

−2 (3g−8g+8) − 9g

Distribute:

= (−2) (3g) + (−2) (−8g) + (−2) (8) + −9g

= −6g + 16g + −16 + − 9g

Combine Like Terms:

=−6g + 16g+ −16+ −9g

= (−6g+16g+−9g) + (−16)

=g+−16

Answer:

=g−16
