The approximate total time using equations of motion takes for the ball to hit the ground is 3.49 seconds, and it travels approximately 69.8 meters horizontally before hitting the ground.

To begin with, we can use the equations of motion to solve for the time it takes for the ball to hit the ground. Since the ball is thrown horizontally, we can ignore the vertical component of the velocity and focus only on the horizontal motion.

First, let's find the horizontal distance the ball travels before hitting the ground. We know that the ball is thrown at a speed of 20 meters per second, so its horizontal velocity will remain constant throughout its motion. We can use the formula:

distance = velocity x time

Since the ball will hit the ground, we want to find the horizontal distance it travels in the time it takes to fall. We know that the height of the tower is 60 meters, so the vertical distance the ball falls is also 60 meters. We can use the formula for the time it takes to fall from a certain height:

time = \(\sqrt{(2 * height / gravity) }\)

where gravity is the acceleration due to gravity, approximately 9.8 meters per second squared. Plugging in the values, we get:

time = \(\sqrt{(2 x 60 / 9.8)}\) = 3.49 seconds

This is the total time it takes for the ball to hit the ground. Now, to find the horizontal distance it travels, we can use the formula above:

distance = velocity x time = 20 x 3.49 = 69.8 meters

Therefore, the approximate total time it takes for the ball to hit the ground is 3.49 seconds, and it travels approximately 69.8 meters horizontally before hitting the ground.

Step-by-step explanation:

The coordinates of the newly created quadrilateral image a'b'c'd' would be

A: (2, - 3)

B: (3, - 1)

C: (- 4, - 2)

D: (2, 3)

A closed quadrilateral has four sides, four vertices, and four angles. It is a form of a polygon. In order to create it, four non-collinear points are joined. Quadrilaterals always have a total internal angle of 360 degrees.

The Latin words quadra, which means four, and latus, which means sides, are combined to form the English term quadrilateral. A quadrilateral does not always have to have equal lengths on each of its four sides. As a result, depending on the sides and angles, we might have several sorts of quadrilaterals.

Answer:

42/17 = 2 8/17

Step-by-step explanation:

Probability of pulling out a red crayon = 6/17

Probability of pulling out a blue crayon = 7/17

They are independent events:

6/17 x 7/17 = 42/17 = 2 8/17

The acceleration of the particle is a = -0.4i + 1.4j lb. The acceleration of the 10 lb particle can be determined by using Newton's second law of motion, which states that the net force acting on an object is equal to the product of its mass and acceleration.

By summing up the individual forces acting on the particle, we can find the acceleration. To determine the acceleration of the particle, we need to find the net force acting on it. According to Newton's second law of motion, the net force is equal to the product of the mass and acceleration of the object. In this case, the mass of the particle is given as 10 lb.

The net force is obtained by summing up the individual forces acting on the particle. In vector form, the net force (F_net) can be calculated by adding the x-components and the y-components of the given forces F1 and F2 separately.

F_net = F1 + F2

In this case, F1 = 3i + 5j lb and F2 = -7i + 9j lb. Adding the x-components gives: F_net_x = 3 lb - 7 lb = -4 lb, and adding the y-components gives: F_net_y = 5 lb + 9 lb = 14 lb.

Therefore, the net force acting on the particle is F_net = -4i + 14j lb.

Using the formula F_net = m * a, where m is the mass and a is the acceleration, we can equate the given mass of 10 lb with the net force and solve for the acceleration.

-4i + 14j lb = 10 lb * a

Simplifying the equation gives: -4i + 14j lb = 10a lb

Comparing the coefficients of the i and j terms on both sides of the equation, we can determine the acceleration. In this case, the acceleration is a = (-4/10)i + (14/10)j lb.

Therefore, the acceleration of the particle is a = -0.4i + 1.4j lb.

Answer:

118.7 inches squared.

Step-by-step explanation:

The area is the total space taken up by a flat (2-D) surface or shape. The area is always measured in square units.

Diameter is the length across the entire circle, the line splitting the circle into two identical semicircles.

The expression for solving the area of a circle is A = π × \(r^{2}\).

To solve for the semicircle above, we can divide the diameter into 2 to get the radius.

So, the radius of the upper semicircle is 6 inches.

If the radius of a circle is 6 inches, then you can substitute r for 6 into the formula.

This simplifies to A = 36π. If a semicircle if half the size of a normal circle, then it will be A = 18π, because 36 ÷ 2 = 18.

To solve for the lower semicircle, we can do the same this as we did above.

But wait, we don't know the radius or diameter!

No worries! To solve for the diameter of the circle, we can take the line that is parallel to the semicircle (the one that has a length of 12in) and subtract 6 from it. We subtract 6 from it because the semicircle takes up the remaining length of the line, not including the 6in.

To solve for the lower semicircle, we can divide the diameter by 2 to get the radius.

So, the radius of the circle is 3.

Now we can insert 3 into the expression.

This simplifies to A = 9π. If a semicircle if half the size of a normal circle, then it will be A = 4.5π because like above, 9 ÷ 2 = 4.5.

Adding the two semicircles together:

So, the area of both semicircles is approximately 70.6858 square inches.

To solve for the area of a rectangle we use the expression:

Inserting the dimensions of the rectangle:

So, the area of the rectangle is 48 square inches.

Adding the two areas together:

Therefore, the area of the entire figure, rounded to the nearest tenth is \(118.7\) \(in^{2}\).

The value of the constant c is -3968.

The given differential equation is\(y = x^2 + (c/x^2)\), and we need to find the value of the constant "c" such that the solution satisfies the initial condition y(8) = 2.

Substituting x = 8 into the equation, we have:

y(8) = \(8^2\) + (c/\(8^2\))

     = 64 + (c/64)

To satisfy the initial condition y(8) = 2, we equate the expression above to 2:

64 + (c/64) = 2

Subtracting 64 from both sides:

c/64 = 2 - 64

c/64 = -62

To isolate "c," we multiply both sides by 64:

c = -62 * 64

c = -3968

Therefore, the value of the constant "c" that produces a solution satisfying the initial condition y(8) = 2 is c = -3968.

Answer:

Wegman's, roughly 3 cents

Step-by-step explanation:

Divide the price by the number of paper towels in the pack to get the unit price.

$15.72/12= $1.31

$13.35/10= $1.335, round since it's money, $1.34

$1.34-$1.31= $0.03 or 3 cents

Wegmans has the better buy, as their unit price is lower.

The difference in unit prices between the two stores is $0.03 per paper towel.

To determine which store has the better buy, we need to compare the unit prices of paper towels at both Wegmans and Tops.

The unit price is the cost per paper towel.

For Wegmans:

Cost of 12 pack of paper towels = $15.72

Number of paper towels in the pack = 12

Unit price at Wegmans = Total cost / Number of paper towels

Unit price at Wegmans = $15.72 / 12 = $1.31 per paper towel

For Tops:

Cost of 10 pack of paper towels = $13.35

Number of paper towels in the pack = 10

Unit price at Tops = Total cost / Number of paper towels

Unit price at Tops = $13.35 / 10 = $1.34 per paper towel

Now, we compare the unit prices:

At Wegmans, the unit price is $1.31 per paper towel.

At Tops, the unit price is $1.34 per paper towel.

The store with the lower unit price has the better buy.

In this case, Wegmans has the better buy, as their unit price is lower.

To find the difference in unit prices:

Difference in unit prices = Unit price at Tops - Unit price at Wegmans

Difference in unit prices = $1.34 - $1.31 = $0.03 per paper towel

So, the difference in unit prices between the two stores is $0.03 per paper towel.
