18. Two planes left an airport at the same time. One flew north at a set speed and the other
Andre45 [30]

Answer: plane A = 333.33mph

Plane B = 500mph

Step-by-step explanation:

Given data:

Distance between the two planes = 2400miles.

Plane A flew North

Plane B flew south

Solution:

Let v represent plane A.

Let 2v represent plane B.

Distance between the two plane

v + 1.5* v = 3*v

7.5v = 2500miles

v = 333.33mph

Plane B has one and half times the speed of plane A

= 1.5 * 333.33

= 500mph

The diameter of the circular base of a spot is 6 inches what is the closet approximation of the area base
AlladinOne [14]

Answer:

A≈28.26 in^2

Step-by-step explanation:

We know the diameter is 6

We can find the radius

r = d/2

r =6/2 =3 inches

The area of a circle is given by

A = pi *r^2

A = pi*3^2

A = pi*9

We will use 3.14 to approximate pi

A ≅(3.14) *9

A≈28.26 in^2

Determine the vertical asymptote for the rational function f(x) = x-4 over 3x +2
Ghella [55]

Answer:  (b) x = -2/3

<u>Step-by-step explanation:</u>

The vertical asymptote is the restriction on x.

The denominator cannot be equal to zero so that it the restriction.

Set the denominator equal to zero and solve for x to find the asymptote.

3x + 2 = 0

3x       = -2

 x       = -2/3
