Please help!!!!!!!!!!!!

Answer:

The answer is below

Step-by-step explanation:

Acceleration is the time rate of change in velocity. Acceleration is given by:

Acceleration = change in velocity / time taken

Acceleration = (final velocity - initial velocity) / time

1) The Ferrari is from rest, hence initial velocity = 0. The final velocity = 100 km/h = \(\frac{100\ km*1000\ \frac{m}{km} }{1\ hr*\frac{3600\ s}{1\ hr} } =27.78\ m/s\), time = 5 s

Acceleration = (0 - 27.78) / 5 = 5.56 m/s²

2) The car has initial velocity = 10 m/s. The final velocity = 10 m/s since velocity is constant. time = 20 s

Acceleration = (10 - 10) / 20 = 0 m/s²

3) The ball has initial velocity = 12 m/s. The final velocity = 0 m/s since it stops. time = 36 s

Acceleration = (0 - 12) / 36 = -0.33 m/s²

A set of numbers that can represent the side lengths, in centimeters, of a right triangle is any set that satisfies the Pythagorean theorem, where the square of the hypotenuse's length is equal to the sum of the squares of the other two sides.

A right triangle is a type of triangle that contains a 90-degree angle. According to the Pythagorean theorem, in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

Let's consider a set of numbers that could represent the side lengths of a right triangle in centimeters.

One possible set could be 3 cm, 4 cm, and 5 cm.

To verify if this set forms a right triangle, we can apply the Pythagorean theorem.

Squaring the length of the shortest side, 3 cm, gives us 9. Squaring the length of the other side, 4 cm, gives us 16.

Adding these two values together gives us 25.

Finally, squaring the length of the hypotenuse, 5 cm, also gives us 25. Since both values are equal, this set of side lengths satisfies the Pythagorean theorem, and hence forms a right triangle.

It's worth mentioning that the set of side lengths forming a right triangle is not limited to just 3 cm, 4 cm, and 5 cm.

There are infinitely many such sets that can be generated by using different combinations of positive integers that satisfy the Pythagorean theorem.

These sets are known as Pythagorean triples.

Some other examples include 5 cm, 12 cm, and 13 cm, or 8 cm, 15 cm, and 17 cm.

In summary, a right triangle can have various sets of side lengths in centimeters, as long as they satisfy the Pythagorean theorem, where the square of the hypotenuse's length is equal to the sum of the squares of the other two sides.

In math, slope is used to describe the steepness and direction of lines

Step-by-step explanation:

a) The contents of register x31 after the following instruction is executed? addi x31, x5, 32 is 277968880 decimal.

b) The contents of register x28 after the following instruction is executed is 278427652 decimal.

c)The contents of register x29 after the following instruction is executed is 1056 decimal

d) The contents of register x29 after the following instruction is executed is 278427652 decimal

In computer architecture, registers are special storage locations within the CPU that hold data temporarily. These registers can hold values in binary, decimal, or hexadecimal formats. In this scenario, we have two registers x5 and x6, holding hexadecimal values. We will use these values to answer the given questions about register manipulation.

a) To determine the contents of register x31 after the instruction "addi x31, x5, 32", we need to add 32 to the value in x5 and store the result in x31. The value in x5 is 01a74cd0hex, which is equivalent to 277968848 in decimal. Adding 32 to this value, we get 277968880 decimal. Therefore, the contents of register x31 after the instruction is executed would be 277968880 decimal.

b) To determine the contents of register x28 after the instruction "add x28, x5, x6", we need to add the values in x5 and x6 and store the result in x28. The value in x5 is 01a74cd0hex, which is equivalent to 277968848 decimal. The value in x6 is 00467b44hex, which is equivalent to 458804 decimal. Adding these two values, we get 278427652 decimal. Therefore, the contents of register x28 after the instruction is executed would be 278427652 decimal.

c) To determine the contents of register x29 after the instruction "ld x29, 1056decimal (x30)", we need to load the value at memory location 1056decimal + the value in register x30 into register x29. The value in register x30 is not given in this scenario, so we cannot determine the contents of register x29.

d) To determine the contents of register x29 after the instruction "sd x28, 16 decimal (x29)", we need to store the value in register x28 at memory location 16 decimal + the value in register x29. The contents of register x28 is 278427652 decimal

Answer:

18ft wide and 33 ft long

Step-by-step explanation:

We are told in the question that:

Cynthia Besch wants to buy a rug for a room that is 20 ft wide and 35 ft long.

The Area of the carpeting she must have = 594 ft²

To solve for this, we have:

Length × Width = Area of a rectangle

594ft² = Length × Width

594ft² = (20 - x) (35 - x)

594 = 700 - 20x - 35x + x²

594 = 700 - 55x + x²

Collect like terms

x² - 55x + 700 - 594

x² - 55x + 106

We factorise

x² - 2x - 53x + 106

(x² - 2x) -(53x + 106)

x(x - 2) -53(x - 2)

(x - 2)(x - 53)

x - 2 = 0, x = 2

x - 53 = 0, x = 53

We choose the least value for x

Hence, x = 2

Length = 20 - 2 = 18ft

Width = 35 - 2 = 33ft

The dimensions the rug should have is 18ft by 33ft, meaning 18ft wide and 33 ft long

Answer:

  $2496

Step-by-step explanation:

You want to know the cost of carpeting a 18 ft by 24 ft room with carpet that costs $52 per square yard.

The dimensions of the room in yards are (18 ft)/(3 ft/yd) = 6 yd, by (24 ft)/(3 ft/yd) = 8 yd.

In square yards, the area is ...

  (6 yd)(8 yd) = 48 yd²

The cost of one square yard of carpet is $52, so the cost of 48 square yards will be 48 times as much.

  (48 yd²)($52/yd²) = $(48·52) = $2496

The total price to carpet the floor is $2496.

__

Additional comment

We're reluctant to call this the total price, as there are usually additional charges for tax, carpet pad, delivery, installation, removal and disposal of old flooring, and possibly additional materials such as tack strips or thresholds. Repairing mold or water damage, or leveling the floor, can also add cost.

Step-by-step explanation:

Consider the format of a line equation, y = mx + b

The slope is represented as the variable 'm.'

Since we already know that the slope is 2, we can input it into the format.

y = 2x + b

Assuming that the point (14, 33) is a point of intersection, we can input these numbers into the equation in order to find the value of b, or the y-intersect.

33 = 2(14) + b

Explanation:

Choice A can be ruled out because of the jump from x to 2x, and from y to 2y. This is a dilation with a scale factor 2. Meaning the preimage enlarges to a bigger image. Specifically the larger image has side lengths twice as long as the smaller preimage. The larger image of course cannot possibly be congruent to the smaller preimage. Congruent figures must have the same corresponding side lengths.

We'll come back to choice B.

Choice C and choice D are ruled out for similar reasoning as choice A was eliminated.

-------------

To summarize the previous section: We ruled out choices A, C, and D. The only thing left is choice B.

Choice B is a translation. The jump from y to y-2 means we shift the point 2 units down. There is no left or right shifting because x stays the same.

For example, the point (5,12) moves to (5,10).

Notice that dilation is not being applied for choice B.

With any geometric translation, aka shifting, the side lengths will remain intact. Something that is 5 units long will stay 5 units long. No amount of shifting will change the distance.

Therefore, a translation preserves distances and lengths. We consider it a rigid transformation. This is why choice B will have the preimage congruent to the image.

Answer:B) (x, y) → (x, y − 2)

Answer:

The cost of the bottle of drink is P4.85. The refund for an empty bottle is 25 thebe.

To express the refund as a percentage of the cost of the drink, we need to convert the refund to the same unit as the cost of the drink.

1 thebe = 0.038 Philippine pesos (as of June 2023)

25 thebe = 0.95 Philippine pesos

Therefore, the refund for an empty bottle is 0.95/4.85 x 100% = 19.59%

So the refund for an empty bottle is 19.59% of the cost of the bottle of drink.

Step-by-step explanation:

Alvin owns a farm with 3 cows, 20 chickens, and 12 ducks. The number of people to find the average cost to pay for their settlements is RM3500.

Generally, To find the average cost to pay for Alvin and Tom's settlement, you will need to add together the total income for both Alvin and Tom and then divide that number by the number of people (in this case, two).

First, let's calculate Tom's weekly income. If Tom earns RM900 a day and there are 7 days in a week, then Tom's weekly income is 900 * 7 = RM6300.

Then, we can add together Alvin's income of RM700 and Tom's income of RM6300 to get the total income for both farmers: 700 + 6300 = RM7000.

Finally, we can divide the total income by the number of people to find the average cost to pay for their settlements:

7000 / 2 = RM3500.

So the average cost to pay for Alvin and Tom's settlement is RM3500.

Answer:

What is Meant by the Reference Angle? In mathematics, the reference angle is defined as the acute angle and it is measuring less than 90 degrees. It is always the smallest angle, and it makes the terminal side of an angle with the x-axis.

Answer: 5 inches

Step-by-step explanation: We must use the Pythagorean theorem to solve this. Since the hypotenuse is always opposite of the right angle, we know that the hypotenuse is 13 and we can substitute the values into this formula: a^2 + b^2 = c^2

12^2 + b^2 = 13^2

144 + b^2 = 169

169 - 144 = 25 (this is b^2)

\(\sqrt{25}\) = 5

Thus, the value of x is 5 inches.

Using the normal distribution, it is found that there is a 0.3192 = 31.92% probability that 20 customers will wait an average of less than 21 minutes to be seated.

The z-score of a measure X of a normally distributed variable with mean \(\mu\) and standard deviation \(\sigma\) is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The parameters for this problem are given as follows:

\(\mu = 23.8, \sigma = 6, n = 20, s = \frac{6}{\sqrt{20}} = 1.3416\)

The probability that 20 customers will wait an average of less than 21 minutes to be seated is the p-value of Z when X = 21, hence:

\(Z = \frac{X - \mu}{\sigma}\)

By the Central Limit Theorem:

\(Z = \frac{X - \mu}{s}\)

\(Z = \frac{21 - 23.8}{6}\)

Z = -0.47

Z = -0.47 has a p-value of 0.3192.

0.3192 = 31.92% probability that 20 customers will wait an average of less than 21 minutes to be seated.
