We can conclude that Donald is the shortest friend.

<h3>Who is the shortest?</h3>

This is a logical question, first, we know that the tallest friend will be on the left side, so we assume that the left position can be discarded, so we need to find who is in the right position.

Barry is not in the center and is not the youngest, so Barry is the tallest friend.

Donald is not in the center, and we know that the youngest must be on the right of Adam. So the only position left for Donald is the right one.

Then, we can conclude that Adam must be on the center and Donald on the right extreme. Then Donald is the youngest and shortest friend.

Select the correct answer. what is the value of this limit? a. b. c. d. e.

dlinn [17]

The value of the limit expression $\lim_{x \to 3} \sqrt{x^2 + 7} + 5$ is 9, and it means that the function approaches 9, as x approaches 3.

<h3>How to evaluate the limit?</h3>

The limit expression is given as:

$\lim_{x \to 3} \sqrt{x^2 + 7} + 5$

This means that we determine the value of the function as x approaches 3.

So, we have:

Limit = √(3^2 + 7) + 5

Evaluate the square

Limit = √(9 + 7) + 5

Evaluate the sum

Limit = √16 + 5

Evaluate the square root

Limit = 4 + 5

Evaluate the sum

Limit = 9

Hence, the value of the limit $\lim_{x \to 3} \sqrt{x^2 + 7} + 5$ is 9

Sergeu [11.5K]

The velocity of an object in free fall increases downwards with time

Please find attached the correct graph showing velocity as a function time, with the positive direction to be upwards.

Reason:

The known parameters are;

Location where the rocks are released; Earth

The time at which rock Y is released = A few seconds after rock X is released.

Required:

To select the graph that shows the vertical velocity of rock, <em>x</em>, as a function of time.

Solution:

Let <em>t </em>represent the time after which rock x are released, with the positive direction being upwards, we have;

The equation for the velocity of x is v = -9.81·t

With the above equation, the graph of the vertical velocity of rock x is plotted with MS Excel.

A conclusion about a plant cell

Veseljchak [2.6K]

Plant cells have certain distinguishing features, including chloroplasts, cell walls, and intracellular vacuoles. Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules.
