A naval engineer uses the function, P, to analyze the effects of water pressure on submarines. The function P(d) measures the pr

essure exerted by water, where d represents the depth of the water in meters. Which of the followin could be a possible domain?
a. d is the set of all integers
b. d is the set off all integers where d is greater than 0
c. d is the set of all rational numbers
d. d is the set of all rational numbers where 0 is less than or equal to d less than or equal to the depth of the sea floor

The function that the naval engineer uses related P (pressure) and d (depth of ocean).

<em>Is there any restriction on the domain ( d: depth of the ocean)? Yes!</em>

The domain would be from 0 (at sea level or 0 depth) until the depth of the ocean (which is not infinite). Hence, we can write:

0\leq d\leq DepthOfSeaFloor

Choice D is the correct one.


ANSWER: D

The first two consecutive odd integers are 1 and 3.
The height has to be 3 since the question implies that the height is exceeds the base. So the base is 1. b = 1 cm

The area of a triangle is base*height*(1/2)
Plug in the values for base and height.
1*3*(1/2)

Simplify. Your final answer should be 1.5 cm^2

What isn't the bets approximation for the area of this circle labeled 8 inches use3.14 to approximate pi
Arte-miy333 [17]

Answer:

50.272  in^2

Step-by-step explanation:

Step one:

Given data

Circles are described using the diameter parameter

Diameter of the circle is 8 inches

radius = 4 inche= d/2

Step two:

The area of the circle is

A= πr^2

A= 3.142*4^2

A=3.142*16

A=50.272  in^2

write a linear equation that intersects y=x^2 at two points. Then write a second linear equation that intersects y=x^2 at just o
Liula [17]

We know that y = x^2 is a parabola, concave up, with vertex in the origin (0,0)

So, we may use three horizontal lines for our purpose: any horizontal line above the x axis will intersect the parabola twice. The x axis itself intersects the parabola once on the vertex, while any horizontal line below the x axis won't intercept the parabola.

Here's the examples:

  • The horizontal line y = 4 intercepts the parabola twice: the system y = x^2,\ y = 4 is solved by x^2=4 \implies x = \pm 2
  • The horizontal line y=0 intercepts the parabola only once: the system is y=x^2,\ y=0 which yields x^2=0\implies x=0 which is a repeated solution
  • The horizontal line y=-5 intercepts the parabola only once: the system is y=x^2,\ y=-5 which yields x^2=-5 which is impossible, because a squared number can't be negative.
