9514 1404 393

Answer:

  (x, y) = (5, -8)

Step-by-step explanation:

The value of y is found by evaluating the equation for x=5.

  y = 7 -3(5) = 7 -15 = -8

For x = 5, y = -8. As an ordered pair, this is (x, y) = (5, -8).

A tepee is designed to have a diameter of 10 ft and a volume of 393 ft. At
Citrus2011 [14]

Answer:

15 ft.

Step-by-step explanation:

The tepee is a cone and its volume

= 1/3 pi r^2 h   where r = radius and h = height.

The radius r = 1/2 * 10 = 5 ft.

So we have the equation:

393 = 1/3*3.14* 5^2 * h

h = 393 / (1/3*3.14*25)

=  15.02 ft.

Orlov [11]
Paralalell means that is has the same slope
y=mx+b
m=slope
y=-1x-2
slope=-1

the equation of a line that passes through the point (x1,y1) and has a slope of m is y-y1=m(x-x1)
given
(2,-2) and slope is -1
y-(-2)=-1(x-2)
y+2=-x+2
minus 2
y=-x
answer is y=-x

Troyanec [42]

Answer:

<em>Dimensions : 1 by 1 by 2 feet,</em>

<em>Volume ⇒ 2 ft^3</em>

Step-by-step explanation:

Here, I can only assume that this rectangular prism is assigned to have dimensions 1 foot by 1 foot by 2 feet;

I can tell that these types of boxes have height and width as the same lengths, so given that;

<em>Dimensions : 1 by 1 by 2 feet,</em>

Volume ⇒ 1 * 1 * 2 ( by definition ) ⇒ 2 ft^3

In other words, <em>Volume ⇒ 2 ft^3</em>

What are the first three terms of the sequence defined by the recursive function an=an-1-(an-2-4), when a5=-2 and a6=0
BaLLatris [955]

Answer:

6, 10, 8

Step-by-step explanation:

aₙ= aₙ₋₁ - (aₙ₋₂ - 4)= aₙ₋₁ - aₙ₋₂ + 4

a₅= -2

a₆= 0

-----------

aₙ₋₂= aₙ₋₁ - aₙ + 4

  • a₄= a₅- a₆ + 4 = -2 - 0 + 4 = 2
  • a₃= a₄ - a₅ + 4 = 2 - (-2) + 4 = 8
  • a₂= a₃ - a₄ + 4 = 8 - 2 + 4 = 10
  • a₁= a₂ - a₃ + 4 = 10 - 8 + 4 = 6

The first 3 terms: 6, 10 and 8
