Answer:

The practical domain for the function f(x) will be [0,5].

Step-by-step explanation:

A model rocket is launched from the ground and its height from the ground is given by f(x), t seconds after its launch.

It is given that the rocket reaches maximum height at t = 2.5 seconds and comes back to the ground after t = 5 seconds.

So, at t = 0 seconds, the rocket was at the ground and hence, t can not be negative and after t = 5 seconds the rocket comes back to the ground and hence, t can not be greater than 5 seconds.

Therefore, the practical domain for the function f(x) i.e. the values of t lies in the interval [0,5]. (Answer)

marysya [2.9K]

Answer:

There are 659 blocks

Step-by-step explanation:

The number of blocks has 9 in the ones place.

The number in the hundreds place is one more that the number in the tens place.

Let the number in the tens place is x.

Number in the hundreds place = 1+x

These two numbers equal 11.

ATQ,

x+1+x = 11

2x + 1 = 11

2x = 10

x = 5

No in the tens place = 5

No. in the hundreds place = 1+5 = 6

Hebnce, the number is 659.

Y&lt;4-2x <br>Will give brainliest and 20 points
icang [17]

Answer:

See the attached for a graph.

Step-by-step explanation:

The edge of the solution space is marked by the line ...

... y = 4 - 2x

This is in slope-intercept form. It has a y-intercept of 4 and a slope of -2. Because the relation symbol is "less than" (with no "or equal to"), the line itself is not part of the solution space. It is graphed as a dashed line for that reason.

The values of y in the solution space are those <em>less than</em> the ones that make up the line, so the shading is of the half-plane <em>below</em> the line.

The volume of a pyramid is the one-third of the product of the area of the base and the height of the pyramid.
V = (1/3)Ah
where
A = area of base
h = height of the pyramid

The base of this pyramid is a hexagon.
The area of a regular hexagon is
A = (1/2)pa,
where
p = perimeter of the base
a = apothem

The perimeter of the hexagon is 6 * 6 ft = 36 ft.
The apothem is shown in the figure and is 5.2 ft.

Area of base: (1/2)pa = (1/2)(36 ft)(5.2 ft) = 93.6 ft^2

Volume = (1/3)Ah = (1/3)(93.6 ft^2)(8 ft)

Volume = 249.6 ft^3

Answer: 250 ft^3
