Twinkle Toes Tony kicked a football, and it landed 100 feet from
also reached a maximum height of 125 feet. Write an equation that models the path of the
ball while it was in the air.

Answers

Answer 1

The equation that models the path of the ball is y =  -0.05·x² + 5·x.

Given,

The distance where the football landed from where it was kicked = 100 feet

The maximum height that the football reached =  125 feet

We have to write an equation that models the path of the ball while it was in the air.

The path may be parabola.

So, equation is like:

y = a·(x - h)² + k

Where;

(h, k) = The coordinate of the vertex (which is the coordinates of the highest point reached by the ball)

Therefore, taking the x-coordinate of the highest point reached by the ball as midpoint of the horizontal distance moved by the ball, we have;

The x-coordinate of the midpoint of the horizontal distance moved by the ball = (50, 0)

We have;

The coordinate of the highest point reached by the ball = (50, 125)

Therefore;

(h, k) = (50, 125)

Substituting the above values in the equation of the parabola gives;

y = a·(x - 50)² + 125

At x = 100, y = 0, which gives;

0 = a·(100 - 50)² + 125 = a·2500 + 125

0 = a·2500 + 125

a = -125/2500 = -0.05

Therefore, we have;

y = a·(x - h)² + k = y = -0.05 × (x - 50)² + 125 = -0.05·x² + 5·x - 125 + 125

y  = -0.05·x² + 5·x - 125 + 125 = -0.05·x² + 5·x

y =  -0.05·x² + 5·x

The equation that models the path of the ball is y =  -0.05·x² + 5·x.

The Australian dollar _______ by ______ %.

a.
appreciated; 5.80

b.
appreciated; 5.48

c.
depreciated; 5.80

d.
depreciated; 4.00

Answers

This indicates that the Australian dollar appreciated by 5.80%. the correct answer is (a) appreciated; 5.80.

To determine whether the Australian dollar appreciated or depreciated and by what percentage, we can calculate the percentage change in value between today and yesterday.

The formula for calculating the percentage change is:

Percentage Change = (New Value - Old Value) / Old Value * 100

Using this formula, we can calculate the percentage change:

Percentage Change = (0.73 - 0.69) / 0.69 * 100

Percentage Change = 0.04 / 0.69 * 100

Percentage Change ≈ 5.80

The percentage change is approximately 5.80%. This indicates that the Australian dollar appreciated by 5.80%.

Therefore, the correct answer is (a) appreciated; 5.80.

Determine whether each of the statements are true or false.1.) There exists a function f such that f(x) < 0, f '(x) > 0, and f ''(x) < 0 for all x. True or False.2.) If f '(x) exists and is nonzero for all x, then f(10) ≠ f(0). True or False.

Answers

1. True. This statement is true because it is possible for a function to have a negative value, positive derivative, and negative second derivative over all x values.

2. True. This is because the derivative of a function is the rate of change of the function.

1. This kind of function has an example in f(x) = x^3 - 3x^2. This function has a first derivative off'(x) = 3x^2 - 6x that is positive for all x values, a second derivative of f''(x) = 6x - 6 that is negative for all x values, and is negative for all x values.

2. The rate of change of the function is always non-zero if the derivative is non zero for all x, and the value of the function at any two locations will not be the same.

Hence, if f '(x) exists and is nonzero for every x, then f(10) ≠ f(0). Consider the function f(x) = x2 as an illustration of this. This function's derivative with respect to x is given by the expression f '(x) = 2x, which is non zero for every x.

As a result, f(10) = 102 = 100 and f(0) = 0, which are clearly not equal.

Thomas bought 120 whistles, 168 yo-yos and 192 tops. He packed an equal amount of items in each bag. A) What is the maximum number of bag that he can get?

Answers

Thomas can pack the items into a maximum of 20 bags, with each bag containing 24 items after calculated with greatest common divisor.

To find the maximum number of bags Thomas can pack, we need to find the greatest common divisor (GCD) of 120, 168, and 192. The GCD will represent the maximum number of items that can be packed into each bag.

To find the GCD, we can use the Euclidean algorithm. First, we find the GCD of 120 and 168:

168 = 1 * 120 + 48

120 = 2 * 48 + 24

48 = 2 * 24 + 0

Therefore, the GCD of 120 and 168 is 24.

Next, we find the GCD of 24 and 192:192 = 8 * 24 + 0

Therefore, the GCD of 120, 168, and 192 is 24.

So, Thomas can pack 24 items into each bag. To find the maximum number of bags he can get, we divide the total number of items by 24:

Total number of items = 120 + 168 + 192 = 480

Number of bags = 480 / 24 = 20

Therefore, Thomas can get a maximum of 20 bags.

In this scenario, P(Z ≤ b) represents the cumulative probability of a standard normal distribution up to the value of b. To find the corresponding value of b, we need to find the z-score that corresponds to a cumulative probability of 0.0311.

By looking up the z-table or using a statistical calculator, we can find that the z-score corresponding to a cumulative probability of 0.0311 is approximately -1.865.

Therefore, the answer is option d. -1.865, as it is the value that satisfies P(Z ≤ b) = 0.0311. The other options (-1.87, -1.86, -1.8) do not correspond to the given cumulative probability.

48. 192

Step-by-step explanation:

In order to get from 3/4 to 3/16, one way would be to divide by 4. Another way is to multiply 3/4 by 1/4.

You can test whether multiplying by 4 works by multiplying 3/4 by 4 and 3 by 4.

When 3/4 is multiplied by 4, it would equal 12/3 which will simplify to 3. This can be done again with 3*4=12.

So the answer would be 12*4 = 48 and 48*4 = 192.

The cone of the volcano has a height of 418 meters and a diameter of 434 meters. Find the volume of the cone. Round your answer to the nearest hundred thousand. Use 3.14 for π.

Answers

First, we need to find the radius of the cone. The diameter is given as 434 meters, so the radius is half of that:

radius = 434/2 = 217 meters

Next, we can use the formula for the volume of a cone:

V = (1/3)πr^2h

where r is the radius and h is the height.

Plugging in the values we have:

V = (1/3)π(217)^2(418)

V ≈ 41,796,778.5

Rounding to the nearest hundred thousand, we get:

V ≈ 41,800,000

Therefore, the volume of the cone is approximately 41,800,000 cubic meters.

Answers

The cost of a tee left over from last year is $10.50.

How to calculate the percentage discount?

Subtract the final price from the original price then Divide this number by the original price. Finally, multiply the result by 100. You've obtained a discount in percentages.

% discount = 100 × (original price - discounted price) / original price

If the regular price of a t-shirt is $20 and it's on sale at 25% off, then the sale price is:

$20 - (25% x $20) = $20 - $5 = $15

If the leftover t-shirts are discounted an additional 30% off the sale price of $15, then the final price is:

$15 - (30% x $15) = $15 - $4.50 = $10.50

Therefore, the cost of a tee left over from last year is $10.50.

Suppose an object is thrown upward with initial velocity of 48 feet per second from a high of 120 feet. The height of the object t seconds after it is thrown is given by h(t)=-16t^2+48t+120. Find the average velocity from t=2 to t=4.
Type your answer as a number with no units.

Answers

The average velocity from t = 2s to t = 4s would be - 48 ft/s.

What are algebraic expressions?

In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that an object is thrown upward with initial velocity of 48 feet per second from a high of 120 feet. The height of the object t seconds after it is thrown is given by h(t) = - 16t² + 48t + 120.

Average velocity

Average rate of change of velocity with time is called average velocity. Mathematically -

v{avg.} = Δx/Δt                                                         .... Eq { 1 }

Δx = x(4) - x(2)

Δx = - 16(4)² + 48(4) + 120 - {- 16(2)² + 48(2) + 120}

Δx = - 96

Δt = 4 - 2 = 2

So -

v{avg.} = Δx/Δt = -96/2 = - 48 ft/s

Therefore, the average velocity from t = 2s to t = 4s would be - 48 ft/s.

Where is the hole for the following function located?f (x) = startfraction x + 3 over (x minus 4) (x + 3) endfractionx = –3y = –3x = 3y = 3

Answers

The function f(x) = (x + 3) / ((x - 4)(x + 3)) has a hole at x = -3, where it is undefined due to division by zero. The function is defined for all other values of x.

To determine the location of the hole in the function, we need to identify the value of x where the function is undefined. In this case, the function has a factor of (x + 3) in both the numerator and the denominator. This means that the function is undefined when (x + 3) is equal to zero, as dividing by zero is not possible.

To find the value of x that makes (x + 3) equal to zero, we set (x + 3) = 0 and solve for x:

x + 3 = 0

x = -3

Therefore, the function f(x) has a hole at x = -3. At this point, the function is undefined, as dividing by zero is not allowed. The function is defined for all other values of x except x = -3.

Answers

It is given that a set of real numbers s is non-empty and bounded. The objective is to prove that inf s ≤ sup s. This statement can be justified as below.

Firstly, as per the definition of bounded set, it is known that the set s has both lower and upper bounds. Thus, the infimum and supremum of s exist and are denoted as inf s and sup s, respectively.

Since s is non-empty and bounded, it can be observed that every element of the set s is greater than or equal to inf s and less than or equal to sup s.

Therefore, inf s is the greatest lower bound of s and sup s is the least upper bound of s, implying that inf s ≤ sup s. Hence, it is proven that inf s ≤ sup s for a non-empty set s of real numbers that is bounded.
