The volume of a cylindrical soap dispenser is modeled by the expression below.select the true statement.a. the expression (x + 1
bulgar [2K]

Answer:

The expression (x+1)^2 represents the radius of the soap dispenser.

The expression 4x+1 represents the height of the soap dispenser.

Step-by-step explanation:

The question says that the soap dispenser is in the form of a cylinder.

Now, we find the volume of the cylinder by using the given formula:

V= \pi r^2 h, where V represents the volume, 'r' represents the radius, and 'h' represents the height of the cylinder.

Now, the volume is the product of radius squared and the height, if they both are functions of x, then the function to represent the volume must have cubic exponents.

Since, the radius is squared in the formula and it is a function of x that implies that the function of radius must have square as the exponent of x, therefore, the expression (x+1)^2 will represent the radius of the soap dispenser and the expression (4x+1) represents the height of the soap dispenser.

Identify the coordinate of the point shown on the number line. A number line from negative 30 to 10. Major tick marks are on eve
DaniilM [7]

Answer:

The coordinates of the point P is -3  

Please see attached number line

Step-by-step explanation:

The given information are;

The length of the given number line = The line extends from -30 to +10

The location of major tick marks = Every ten numbers

The location of minor tick marks = Every number

The location of the point P = Three ticks to the left of 0

Therefore, the coordinates of the point P = -3

How to find the sum of the forces in the y direction of an elevator?
lukranit [14]

A cardboard box rests on the floor of an elevator. The box has a mass m = 3.75 kg and the elevator has an upward acceleration of a

Part a. Select the Free Body Diagram for the system
Part b. Write an expression for the sum of the forces actinv on the box in the y direcion, given that up is the positive y direction. Your answer should be in terms of FN, m, g.
Part c. Write an expression for the normal force FN, that the block experiences in terms of the elevator's accelaration, the block's mass and the accelaration of gravity
Part d. If the elevator's accelaration has a magnitude of g in the downward direction, what would the normal force FN1 be in Newtons? (Numerical value)
Part e. If the elevator's accelaration had a magnitude of g in the upward direction, what would the normal force FN2 ve in Newtons? (Numerical value)

What is the surface area of this triangular pyramid the height is 4 the base and width is 4 and the bottom back line is 4 and th
valentinak56 [21]

Answer:

37 yd²

Step-by-step explanation:

The computation of the surface area of this triangular pyramid is shown below:

The surface area of this triangular pyramid  is

But before that

Lateral area = 3(1 ÷ 2) × base × height

= (3 ÷ 2)(4 yd)(5 yd)

= 30 yd²

Now

base area = 1 ÷ 2 × base × height

= 1 ÷ 2(4 yd)(3.5 yd)

= 7 yd²

Now the total surface area is  

surface area = lateral area + base area

= 30 yd² + 7 yd²

= 37 yd²
