EGG DROP The physics class is holding an egg drop competition. The formula h= −16t2+h0 can be used to approximate the number of seconds, t, it will take for the eggs to reach height, h, from an initial height of h0 in feet.

Find the time it takes an egg to reach the ground if it is dropped from an initial height of 40 feet. Round to the nearest hundredth, if necessary.

Answer:9

Step-by-step explanation:addition and subtraction done in order of appearance. 5+20-16

5 + 20 - 4²

Add 5 and 20 to get 25.

25 - 4²

Calculate 4 to the power of 2.

To calculate a power, multiply the base as indicated by its exponent.

So 4 is multiplied 2 times, so

25 - 16

Subtract 16 from 25 to get 9.

Answer:

ac = 18

Keys:

[tex]\sf Given\\a = 2\\c = 9\\ac = a \cdot c[/tex]

Step-by-step explanation:

[tex]\sf a(2) \cdot c(9) = 18[/tex]

Answer:

The answer would be 18.

Step-by-step explanation:

ac is equal to a multiplied y c. Since we know that a is equal to 2 and c is equal to 9, we know we have to set up the equation 2(9). (Note: The parentheses around the 9 means you multiply by that number). 2 times 9 is equal to 18, getting you your answer. I hope this helps! :)

After the construction of a circle, we have to "Set the compass to the radius of the circle" so, option C is correct.

A regular hexagon is defined as a closed shape consisting of six equal sides and six equal angles. The sum of the measure of angles of a regular hexagon is 120 degrees.

Steps to create an inscribed hexagon:

1: The structure needs to adjust the box thickness towards that radius.

2: Afterward moves around the outside of the circular path to just produce the 6 vertices of that similar hexagon.

"Set the compass to the radius of the circle" so, option C is correct.

Answer:

  Construct a circle first

Step-by-step explanation:

If you're going to inscribe any figure in a circle, the first construction you need to do is construct the circle.

Additional comment

The attached shows our construction of an inscribed square and an inscribed regular hexagon. Here are the steps we used. You will notice the first step is construct a circle. (It could be, construct line AB, then construct circle A with radius AB.)

We have used line AB in the construction of the hexagon, but the hexagon could have been constructed without it. That is why "construct a circle first" is likely a better choice for a common first step.

square

regular hexagon

__

Arguably, the first step to constructing a circle is set the compass to the radius. We chose to ignore this because one of the ways to construct an inscribed hexagon is to mark off successive arcs around a circle that have a radius equal to the radius of the circle. We did not use that method. (The use of diameter BC made drawing 5 arcs around the circle unnecessary. We drew 2 instead.)

Or, you could argue that construct a line first is needed before you set the compass to the radius. If this is the first step, then the next steps would be to mark the center of the circle on the line, and mark another point at a distance of the radius from that center point.

What you consider to be the first step depends on the level of detail you want to attend to.

A circle is a curve sketched out by a point moving in a plane. The measure of the ∠ACB or θ is 50°.

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

In order to solve the problem, we need to draw a line segment AB. Since A is the center of the circle AC and AC both will be the radius of the triangle ΔABC. Since two sides of the triangle are equal, the measure of ∠ABC and ∠ACB will be equal therefore, we can write,

∠ACB + ∠ABC + ∠BAC = 180°

2∠ACB + 80° = 180°

∠ACB = 50°

Hence, the measure of the ∠ACB or θ is 50°.

However, when the first term is represented by a₀ instead of a₁.

It means that the sequence has an initial value, other than the first term.

Even though the words "first" and "initial" are synonyms, they do not entirely represent the same thing.

Take for instance, a₀ can be used instead of a₁ in the following scenario

The population of a country is 1000 in 1996 and The country experiences an increment of 250 people every year after 1996.

The above means that:

By concept of capacity and the assumption of constant flow rate, the amount of ounces of juice in the container after 6 seconds is 20 ounces.

Given that the additional juice is added to the container at constant rate. Hence, the final capacity (C'), in ounces is equal to the sum of the initial capacity (C), in ounces, and the product of the flow rate (q), in ounces per second, and time (t), in seconds.

C' = C + q · t     (1)

If we know that C = 9.5 oz, q = 1.75 oz/s and t = 6 s, then the final capacity of the container is:

C' = 9.5 oz + (1.75 oz/s) · (6 s)

Area of lateral faces (triangle and there are 4 of them):

A = bh/2

A = 3(4)/2

A = 12/2

A = 6

Since there are 4 lateral faces, multiply the area by 4.
