The ball reached its maximum height at a time of 1 second.

In this problem we have the case of a ball that experiments a free fall, that is, a case of an uniform accelerated motion due to gravity. The position of the ball as a function of time is represented by a quadratic equation:

y' = y + v · t + 0.5 · g · t²

Where:

And to determine the time related to the highest point, we need to rearrange the expression into its standard form:

y' - k = C · (t - h)²

Where:

First, write the quadratic equation:

y' = y + v · t + 0.5 · g · t²

y' = 10 + 16 · t - 8 · t²

Second, complete the square until the standard form is found:

y' - 10 = 16 · t - 8 · t²

y' - 10 = - 8 · (t² - 2 · t)

y' - 18 = - 8 · (t² - 2 · t + 1)

y' - 18 = - 8 · (t - 1)²

The ball takes a time of 1 second to reach its maximum height.

The total displacement in km and vector form in the form of i and j is 35.8 a[x] km + 0 a[y] km.

According to the question,

We have the following information:

A cyclist rode his bike for 169 min at an average velocity of 3. 53 m/s on a bearing of 450.

Now, we know that the following formula is used to find the velocity:

Velocity = displacement/time

(We will convert time from minutes into seconds.)

Displacement = 3.53*(169*60)

Displacement = 35794.2 m

Now, the displacement in km will be 35.8 km approximately.

Now, let's take that the bike is moving along the positive x-axis. So, it would be written in the following expression:

Displacement = 35.8 a[x] km + 0 a[y] km

Hence, the total displacement in km and vector form in the form of i and j is 35.8 a[x] km + 0 a[y] km.

The value of that maximize the profit, und determine the corresponding price and total profit for the level of production is $52,500

Given,

Suppose that the demand equation for a monopolist is p=100−.02x and the cost function is C(x)=20x+10,000. Find the value of x that maximizes the profit and determine the corresponding price and total profit for this level of production.

Here we need to find the value of that maximize the profit.

As per the Monopolist maximizes profit by setting marginal costs (MC) equal to marginal revenue (MR).

Here the Marginal revenue is the first partial derivative of Total revenue (TR) function.

And the total revenue is the quantity (X) times price (P):

TR = P⋅X

=> (100−0.01X) X

=> 100X−0.02X

Then we get get marginal cost, take the partial derivative of the cost function with respect to x:

=> MC=∂c(X)/∂X:50

=> MR=MC/100−0.02X=50/100−50

=> 0.02X

=> 2500units

Then the price of X, plug in the value of x in the inverse demand function and solve for price:

=> P=100−0.01(2500)=$75

And the profit is the difference between Total revenue and Total costs:

=> ∏=TR−TC/TR = P⋅X

=> $75 × 2500 = $187,500

Finally, the total costs, plug in the value of x in the total cost function:

=> TC = 50(2500)+10,000

=> $135,000

=> ∏ = $187,500−$135,000

=> $52,500

The area of the semicircle is 39.275 square cm

From the question, we have the following parameters that can be used in our computation:

Diameter = 10 cm

Start by calculating the radius of the semicircle

So, we have the following representation

radius = Diameter/2

This gives

radius = 10/2

Evaluate

radius = 5

The area of the semicircle is then calculated as

Area = πr²/2

So, we have

Area = 3.142 * 5²/2

The probability of getting a head given that probability of getting a tail is   0. 52 is  0.48.

Probability of getting at least one head is equal to the probability of all events (100 percent, or 1) less the likelihood of receiving all tails .

a. The constant of variation is 1.3.

b. Initially the tree is  29.1 cm.

c. The equation showing this relationship is y = 1.3x + 29.1.

d. After  12.2 weeks many weeks will the plant be 45 cm tall.

e. 16.85 weeks of time has gone by when the plant is 51.3 cm tall.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at

x = 0.

a. The constant of variation is (y₂ - y₁)/(x₂ - x₁) = (38.2 - 33)/(7 - 3).

= 1.3.

∴ 38.2 = (1.3)7 + b.

38.2 = 9.1 + b.

b = 29.1.

y = mx + 29.1.

b. Now initial constant of variation m = 0.

So, y = 29.1 (cm).

c. The equation showing this relationship is y = 1.3x + 29.1.

d. 45 = 1.3x + 29.1.

1.3x = 15.9.

x = 15.9/1.3.

x = 12.2 weeks.

e. 51 = 1.3x + 29.1.

1.3x = 21.9

x = 16.85 weeks of time have gone.

The axis of symmetry of equation y = 3x² - 18x + 5 is x = 3.

The object's shape becomes symmetrical when a straight line acts as the axis of symmetry. Each side of the axis of symmetry produces a perfect reflection of the other. It can be lateral, vertical, or any combination of the three.

Given equation:

y = 3x² - 18x + 5

The line symmetry of y =  [tex]ax^2+bx+c = 0[/tex]  is x = -b / 2a,

The number of feet of light used by Chad is 176 feet

From the question, we have the following parameters that can be used in our computation:

Length = 55 feet

Width = 48 feet

We start by calculating the distance from the end of the width till the beginning of the length

This is represented by the following Pythagoras theorem

Distance = √(Length² + Width²)

So, we have

Distance = √(55² + 48²)

Evaluate

Distance = 73

The number of feet is then calculated as

Feet = Length + width + distance

So, we have

Feet = 55 + 48 + 73

Evaluate

Feet = 176
