The time at which both balls are at the same height is t = 2.48 seconds and the balls meet at a height of approximately 125.44 feet.

To find the height at which the balls meet, we need to set the two equations equal to each other:
-16t^2 + 56t = -16t^2 + 156t - 248

By simplifying the equation, we can cancel out the -16t^2 terms and rearrange it to:
100t - 248 = 0

Next, we solve for t by isolating the variable:
100t = 248
t = 248/100
t = 2.48 seconds

Now, we substitute this value of t into one of the original equations to find the height at which the balls meet. Let's use the first equation:
h = -16(2.48)^2 + 56(2.48)
h ≈ 125.44 feet
So, the balls meet at a height of approximately 125.44 feet.

The value is approximately equal to 12.0711°

While measuring angles, we use various units of measurements such as the degrees or the SI unit radians as per our convenience.

When we use the degree system, we can use the degree-minute-second or the degree decimal system as per our requirement of precision.

The angle in degree - minutes - seconds is 12°4'16"

We know that \(\frac{1}{60}\) of a degree is minute and \(\frac{1}{60}\) of a minute is a second.

Hence, \(\frac{1}{3600}\) of a degree is a second.

Therefore the angle \(\theta\) in degrees and decimal fractions of degrees will be:

\(\theta\) = \(12+\frac{1}{60}\) × 4 + \(\frac{1}{3600}\) × 16

 = \((12+\frac{1}{15}+\frac{1}{225} )\)°

If Rachana randomly selects two mugs from the set, the probability that she gets two different mugs is 0.1556 or 15.56%.

To solve this problem, we can use the concept of combinations. Since there are 10 mugs in the set, there are 10 choose 2 = 45 ways to select two mugs without considering order.

Out of these 45 ways, we need to count the number of ways Rachana can select two different mugs. Since there are 3 different types of mugs, Rachana can choose any one of the three types for the first mug. There are 10 mugs in the set, out of which 3 belong to the chosen type. Therefore, the probability of choosing a mug of the chosen type is 3/10.

For the second mug, Rachana can choose from the remaining 9 mugs. Since she needs to choose a different type of mug, she can choose any one of the 2 remaining types. There are 7 mugs left from the other 2 types. Therefore, the probability of choosing a mug of a different type is (7/9) * 2/3 = 14/27.

Therefore, the probability of selecting two different mugs is the product of the probabilities of selecting a mug of the chosen type and a mug of a different type. This is given by (3/10) * (14/27) = 7/45, which is approximately 0.1556 or 15.56%.

The value of x for the given triangles is 48.

Two objects are said to be comparable if they have the same shape. Therefore, two figures are said to be comparable in mathematics if they share the same shapes, lines, or angles.

Given that there are two triangles. The two triangles are similar to each other.

The value of x will be calculated by applying the property of similarity in the two triangles.

(18+x) / (56+21) = x / 56

(18+x) / ( 77 ) = x / 56

1008 + 56x = 77x

1008 = 21x

You can make a maximum of two tomato-cheese sandwiches. because you can only make as many tomato-cheese sandwiches as the number of cheese slices you have

To make a tomato-cheese sandwich, you need one tomato slice and one cheese slice. Since you have three tomato slices and two cheese slices, you are limited by the availability of cheese slices.

Therefore, you can only make as many tomato-cheese sandwiches as the number of cheese slices you have, which in this case is two.

The ingredient that limits the number of sandwiches you can make is the cheese slice. You have more tomato slices than cheese slices, so you cannot make more than two tomato-cheese sandwiches.

Even if you have extra tomato slices, you cannot make additional sandwiches because you do not have enough cheese slices to pair with them.

In summary, the number of tomato-cheese sandwiches you can make is determined by the ingredient with the lowest quantity,

which in this case is the cheese slice. Therefore, you can make a maximum of two tomato-cheese sandwiches.

The characteristic feature of all alkenes is the presence of one or more carbon-carbon double bonds.

Alkenes are a class of hydrocarbons that contain carbon-carbon double bonds (C=C). These double bonds are formed by the sharing of two pairs of electrons between two carbon atoms.
This double bond configuration imparts unique chemical and physical properties to alkenes, distinguishing them from other classes of hydrocarbons.

The presence of one or more carbon-carbon double bonds is the defining characteristic of alkenes. This feature gives alkenes their reactivity and makes them prone to undergo addition reactions, where atoms or groups of atoms add to the double bond to form new compounds.
The presence of double bonds also affects the physical properties of alkenes, such as their boiling points, melting points, and solubility.

In contrast, alkanes, another class of hydrocarbons, do not possess double bonds and are characterized by single carbon-carbon bonds. Alkynes, yet another class of hydrocarbons, contain carbon-carbon triple bonds (C≡C).
Therefore, the presence of one or more carbon-carbon double bonds specifically distinguishes alkenes from other hydrocarbon classes.

The x-component, y-component, and magnitude of the vector -3.5A.

(a) To find the x-component of the vector -3.5A, we need to multiply the x-component of vector A by -3.5. The x-component of vector A can be found using the formula:

x-component = |A| * cos(θ), where |A| is the magnitude of vector A and θ is the angle it makes with the positive x-axis. Substituting the given values, we have: x-component = 56.8 m * cos(145°).

Evaluating this expression gives us the x-component of -3.5A.

(b) To find the y-component of the vector -3.5A, we multiply the y-component of vector A by -3.5.

The y-component of vector A can be found using the formula: y-component = |A| * sin(θ), where | A| is the magnitude of vector A and θ is the angle, it makes with the positive x-axis.

Substituting the given values, we have:

y-component = 56.8 m * sin(145°). Evaluating this expression gives us the y-component of -3.5A.

(c) The magnitude of the vector -3.5A can be found using the Pythagorean theorem: |-3.5A| = √((x-component)^2 + (y-component)^2).

By substituting the calculated values of the x-component and y-component into this equation, we can find the magnitude of -3.5A.

Step-by-step explanation:

Since the base angles are congruent, then the triangle is isosceles and

AB = BC , that is

5x - 19 = 2x + 11 ( subtract 2x from both sides )

3x - 19 = 11 ( add 19 to both sides )

3x = 30 ( divide both sides by 3 )

x = 10

Then

AB = BC = 2x + 11 = 2(10) + 11 = 20 + 11 = 31

Complete Question:-

The distance and average speed of bunny are  39 units and 780 units per hour.

The bunny hopped from \($-5 to 34$\) on the number line, which means it hopped a distance of:

\($$34 - (-5) = 34 + 5 = 39$$\)

Therefore, the bunny hopped a distance of 39 units.

To find the average speed of the bunny, we need to divide the distance it traveled by the time it took:

\($\text{Average speed} = \frac{\text{Distance traveled}}{\text{Time taken}}$$\)

The time taken by the bunny was 3 minutes, or \($\frac{3}{60}$\) hours. Therefore, the average speed of the bunny was:

\($\text{Average speed} = \frac{39}{\frac{3}{60}} = \frac{39 \times 60}{3} = 780 \text{ units per hour}$$\)

Therefore, the bunny's average speed was 780 units per hour.

The annual growth rate (APY) for this investment is 0.48%. This means that the account will grow 0.48% each year.  This is equivalent to an APR of 4.8%.

The function below shows the value of the account after t years, where the annual growth rate can be found from a constant in the function and all coefficients are rounded to four decimal places.

V(t) = 220 * (1 + 0.00480)t

The annual growth rate (APY) can be calculated by taking the natural logarithm of both sides of the equation and solving for the rate.

ln(V(t)) = ln(220 * (1 + 0.00480)t)

ln(V(t)) = ln(220) + ln((1 + 0.00480)t)

ln(V(t)) = ln(220) + t*ln(1 + 0.00480)

Taking the derivative of both sides with respect to t yields:

(1/V(t)) * (dV(t))/dt = ln(1 + 0.00480)

Solving for the rate:

r = (1/V(t)) * (dV(t))/dt/t = ln(1 + 0.00480)/t

The annual growth rate (APY) for this investment is 0.48%. This means that the account will grow 0.48% each year.  This is equivalent to an APR of 4.8%.
