The volume of this right prism is 240.5 ft³. What is the height, x, of the prism? Enter your answer as a decimal in the box.
Answers
Answer:
7.4 is the correct answer
Step-by-step explanation:
Height 'x' of the given right prism is 7.4 feet.
Volume of right prism:What information do we have?
Height of base = 5 ft
Length of first parallel line = 5 ft
Length of Second parallel line = 8 ft
Volume of prism = 240.5 ft³
Volume of prism = Area of base × height
Volume of prism = (1/2)(sum of parallel line)(Height) × height
240.5 = (1/2)(5+8)(5) × height
240.5 = (1/2)(13)(5) × height
240.5 = 32.5 × height
Height of prism = 7.4 feet

The z-values, standard deviations, and sample sizes that produce a margin of error of 0.95 is z = 2.14; s = 4; n = 81.
What is the margin of error?The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The wider the margin of error, the less confident one should be that a poll result reflects the outcome of a population-wide survey.
The formula of the margin of error is given by the formula,

A.) z = 2.14; s = 4; n = 9
The margin of error is,

A circle can be represented as an equation or on a graph
The equations of the circles are [tex]x^2 + y^2 = 36[/tex] and [tex](x + 4)^2 + (y + 2)^2 = 16[/tex]
How to graph the circlesThe equation of a circle is represented as:
[tex](x - a)^2 + (y - b)^2 =r^2[/tex]
Where:
Center = (a,b)
Radius = r
For circle A, we have the equation to be:
[tex](x - 0)^2 + (y - 0)^2 =6^2[/tex]
[tex]x^2 + y^2 = 36[/tex]
For circle B, we have the equation to be:
[tex](x + 4)^2 + (y + 2)^2 =4^2[/tex]
[tex](x + 4)^2 + (y + 2)^2 = 16[/tex]
Hence, the equations of the circles are [tex]x^2 + y^2 = 36[/tex] and [tex](x + 4)^2 + (y + 2)^2 = 16[/tex]

The kinetic energy of an object is given by:
Kinetic energy = 1/2 * mass * velocity²
If the kinetic energy of the pendulum at the top of its swing is 0, then this tells us that the velocity of the pendulum at that point is 0. All of the kinetic energy is converted to potential energy, and the pendulum starts moving in the opposite direction after this point in time.
Answers
Answer:
TYSM!! I wanted to know how to calculate the kinetic energy of an object for so long!
A pendulum at the top of its swing, when it stops moving does not have any speed and therefore it has no kinetic energy.
What is kinetic energy?Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force.
Given that, Kinetic energy = 1/2 × mass × velocity²
If the kinetic energy of the pendulum at the top of its swing is 0, then this tells us that the velocity of the pendulum at that point is 0.
Here, mass m = 0, This shows that the pendulum has no mass and
velocity (v) = 0 meaning the velocity is zero, it is stopped at once.
The velocity that is moving one way or direction can be said to be in a positive direction or positive velocity.
It does slows down when it reaches the top of its swing then move again back to the opposite direction making it to move in the opposite or negative direction with negative velocity. This make a positive velocity and a negative velocity which has pass through to be zero.
Therefore, a pendulum at the top of its swing, when it stops moving does not have any speed and therefore it has no kinetic energy.

Profit = revenue - cost = 7500 - 8425 = -925
Profit = -925
The negative profit means the merchant lost money.
