Start from the last plane.
Rachel's plane flew 20 ft.
Darren's plane flew twice as far as Rachel's,
so Darren's plane flew 2 * 20 ft = 40 ft.
Amanda's plane flew 19 ft farther than Darren's,
so Amanda's plane flew 40 ft + 19 ft = 59 ft.

Answer:

59 ft

Step-by-step explanation:

Given;

  • Amanda plane flew 19 ft farther than Darren plane
  • Darren plane flew twice as far ad Rachel plane
  • Rachel plane 20 ft

Then Darren's plane must have flown (2 × 20ft) = 40 ft

Amanda's plane would have flown (40ft + 19ft) = 59 ft

Amanda's plane flew 59 ft far.

What is the remainder of f(x)=x^4-2x^3-27x^2-9x+18 when divided by binomial x+4
givi [52]

Answer:

The remainder will be 6.

Step-by-step explanation:

We have the function:

f(x)=x^4-2x^3-27x^2-9x+18

And we want to find the remainder after it is divided by the binomial:

x+4

We can use the Polynomial Remainder Theorem. According to the PRT, if we have a polynomial P(x) being divided by a binomial in the form (<em>x</em> - <em>a</em>), then the remainder will be given by P(a).

Here, our divisor is (<em>x</em> + 4). We can rewrite this as (<em>x</em> - (-4)).

Therefore, <em>a</em> = -4.

Then according to the PRT, the remainder will be:

f(-4)=(-4)^4-2(-4)^3-27(-4)^2-9(-4)+18=6

The remainder will be 6.

The distance between earth and moon is 384000000 m. this distance can be expressed as ____m
zalisa [80]

This distance can be expressed as 3.84× 10^{8} m.

What is distance with example?

  • Distance is a scalar quantity.
  • The distance of an object can be defined as the complete path travelled by an object.

Given the distance between the earth and the moon is 384000km

Representing in exponential notation,

=384000×1000m  [∵1km=1000m]

=384× 10^{6} m

=3.84× 10^{8} m
