Step-by-step explanation:

The completed statements with regards to the projectile motion of the football are presented as follows;

This graph is a nonlinear function

The hang time of the football is 3 seconds

The football reaches its maximum height when t = 1.5 seconds

The maximum height is about 11 meters

For t between t = 0 and t = 1.5, the height is increasing

The motion of a projectile is one that involves an object thrown into the air or into space, which is acted upon by only gravitational force.

The graph in the question, showing the scale on the x-axis obtained from a similar question on the internet, indicates that we get;

The x-intercept of the graph are; (0, 0), and (3, 0)

Therefore;

The time the football is in the air, which is the hang time of the football can be obtained from the difference between the x-values of the x-intercept as follows;

Hang time = 3 - 0 = 3

The graph indicates that the coordinates of the maximum height is (1.5, 11). Therefore;

The height at t = 0 is 0 meters, and the height at t = 1.5 seconds is 11 meters, therefore; the height is increasing between t = 0 and t = 1.5 seconds

For t between t = 0 and t = 1.5, the height is increasing

The time taken by population of bacteria to be doubled whose normal growth is six fold in 10 hours is equal to 3.87 hours.

Let us consider 'n' is the time taken by the bacteria populations.

And P(n) represents the population of the bacteria in time 'n'

Using exponential growth function we know,

P(n) = K e^(a× n)

Where K and 'a' are the constants.

From the given condition we have :

P(10 ) = 6 P(0)

⇒ K e^ (10a) = 6k e^(0 × a )

⇒ e^(10a) = 6

⇒ 10a = log 6

⇒ a = ( log 6 ) / 10

Now required time when population is double :

P(n ) = 2P(0)

⇒  K e^ (n × a) = 2k e^(0 × a )

⇒ e^ [ n ×( log 6 ) / 10 ] = 2

⇒ n ×( log 6 ) / 10 = log 2

⇒ n = ( 10 × log 2 ) / log 6

⇒ n =  ( 10 × 0.3010 ) / 0.7782

⇒ n = 3.8679 hours

⇒ n = 3.87 hours

Therefore, the population of the bacteria will take 3.87 hours to get double.

The above question is incomplete , the complete question is:

A bacteria population increases sixfold in 10 hours. Assuming normal growth, how long did it take for their population to double?

Answer: Since triangle QRS and triangle TUV are both triangles, we can use the fact that the sum of the interior angles in a triangle is 180 degrees.

In triangle QRS, the measure of angle Q is 117 degrees and the measure of angle R is 180 - 117 = 63 degrees. The measure of angle S is 180 - 63 = 117 degrees, since the angles in a triangle add up to 180 degrees.

In triangle TUV, the measure of angle T is 180 - 30 = 150 degrees and the measure of angle U is 30 degrees. The measure of angle V is 180 - 150 = 30 degrees, since the angles in a triangle add up to 180 degrees.

The measures of LQ and LS can be found using the fact that the exterior angle of a triangle is equal to the sum of the measures of the two interior angles that are not adjacent to it.

The measure of LQ is equal to the sum of the measures of angles R and T:

LQ = 63 + 150 = 213 degrees

The measure of LS is equal to the sum of the measures of angles Q and U:

LS = 117 + 30 = 147 degrees

So the measure of LQ is 213 degrees and the measure of LS is 147 degrees.

Answer:

A semicircle can be drawn by first drawing a diameter of a circle, which is a line segment connecting two points on the circumference that passes through the center of the circle. Then, the semicircle can be constructed by drawing an arc that is half of the circumference of the circle and connecting the ends of the arc to the endpoints of the diameter.

A quarter circle can be drawn in a similar way, but instead of drawing an arc that is half of the circumference, you would draw an arc that is a quarter of the circumference. To do this, you would need to find the central angle that subtends the arc and divide it by 4. The quarter circle can then be constructed by drawing an arc with this central angle and connecting the ends of the arc to the endpoints of a radius of the circle, rather than the diameter.

In both cases, you can use a compass or a protractor to accurately draw the arcs.

Step-by-step explanation:

x current age of the father

y current age of the son

first equation (x-4)+(y-4)=27 so x=27+4+4-y=35-y

second equation (y+5) : (x+5)= 2:7

so (y+5)*7=(x+5)*2

let's replace x we found at the first equation with the one at second equation

(y+5)*7=(35-y+5)*2

7y+35=(40-y)*2

7y+35=80-2y

7y+2y=80-35

If Lin walks at a speed of 2. 5 miles per hour. Andre walks at a speed of 3 miles per hour. It will take 4 hours until Lin and Andre meet on the path.

Lin and Andre are walking toward each other on a 22-mile trail, so they will meet when the sum of the distances they have walked is equal to 22 miles. Let's call the time they walk until they meet "t".

During this time, Lin will have walked a distance of 2.5t miles, and Andre will have walked a distance of 3t miles. The sum of these distances is equal to 22 miles, so we can set up the equation:

2.5t + 3t = 22

Combining like terms, we get:

5.5t = 22

Dividing both sides by 5.5, we get:

t = 4

So it will take Lin and Andre 4 hours to meet on the path.

Note that we could have also solved this problem by using the formula:

time = distance / speed

For Lin, the time to cover the 22-mile distance would be:

time = distance / speed = 22 / 2.5 = 8.8 hours

For Andre, the time to cover the 22-mile distance would be:

time = distance / speed = 22 / 3 = 7.33 hours

Since they are walking towards each other, we can add their times to get the time it takes for them to meet:

time = 8.8 + 7.33 = 16.13 hours

However, we can see that this answer is not correct, as it is greater than the time it would take for either of them to cover the entire distance. This is because the time it takes for them to meet is less than the sum of their individual travel times, due to them moving towards each other.

So we go back to our original equation and solve for "t" to get the correct answer of 4 hours.

Answer: 20

Step-by-step explanation:

30-60-90 triangles are special: Their side lengths fall in a ratio of 1:2:[tex]\sqrt{3}[/tex], in order of Shortleg : hypotenuse : longleg

Since we know the short leg is 10, the hypotenuse must be double, or 20.

The required measure of angle m∠Q is 42 degrees, as of the given condition.

The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should equal to 180°

Here,
In a triangle, the sum of the angles is always equal to 180 degrees. Therefore, for triangle OPQ,

m∠O + m∠P + m∠Q = 180°

Using the given information,

m∠O = (6x - 14)°

m∠P = (2x + 16)°

m∠Q = (2x + 8)°

(6x - 14)° + (2x + 16)° + (2x + 8)° = 180°

10x + 10 = 180°

10x = 170

x = 17

Substituting the value of x back into the expression for m∠Q,

m∠Q = (2x + 8)°

m∠Q = (2 * 17 + 8)°

m∠Q = 42°

So the value of m∠Q is 42 degrees.

Given: A road is being extended by construction workers. The road already had a length of miles, and the crew is continuously extending it by miles. Let the number of days the crew has worked and the distance of the entire road (in miles) be represented by D and L respectively. Create a corresponding equation L to D.

According to the inquiry,

The road's initial length is 52 miles.

To estimate the probability that a randomly selected person would pass the driving test on the first attempt, we can divide the number of people who passed on the first attempt (6500) by the total number of people who took the test (10,000).

Probability = Number of favorable outcomes / Total number of possible outcomes.In this case, the favorable outcome is passing the test on the first attempt, and the possible outcomes are all the people who took the test.

Probability = 6500 / 10000= 0.65

Therefore, the estimated probability that a randomly selected person would pass the driving test on the first attempt is 0.65 or 65%. This means that there is a 65% chance that a randomly selected person from the group of 10,000 would pass the driving test on their first try.

so if we get the denominator to 100, the numerator is the percent of the equation

however we have to divide the numerator aswell as if we don't, we simply just half the equation.

54/2 = 27

200/2 = 100

27/100 is the new equation. referring back to the first statement, i made, the numerator would be the percent of the equation that is a part of 100
