Answer:

x = [tex] 4 \sqrt { 3 } [/tex]

Step-by-step explanation:

We are given a diagram of a pyramid with a right angled triangle which has [tex]30[/tex]°, [tex]60[/tex]° and [tex]90[/tex]° angles an the hypotenuse is [tex]8cm[/tex].

Since we have a right angled triangle, we can apply sin here:

We know that [tex]sin 60 = \frac{\sqrt{3} }{2}[/tex] so we can write it as

[tex]\frac{\sqrt{3} }{2} = \frac{x}{8}[/tex]

So we get the slant height of x = [tex]4\sqrt{3}[/tex].

Answer:

The slant height of square pyramid = 4√3 m

Step-by-step explanation:

From the figure we can see a square pyramid with lateral edge 8 m

Also the one angle of face triangle is 60° , therefore the face triangle is an equilateral triangle.

Therefore the base is 8 m

To find the slant height

slant height² = Lateral edge² - (base/2)²

    = 8² - (8/2)² = 8² - 4²

    = 64 - 16 = 48

Slant height = √48 = 4√3 m

Therefore slant height of square pyramid =  4√3 m

Final answer:

The engineering professor's choice of new computer models over time can be modeled using a Markov chain, with specific transition probabilities for moving between models M1, M2, and M3. These probabilities are used to construct a transition matrix that allows us to analyze the selection pattern.

Explanation:

The scenario described can be represented as a Markov chain, which is a mathematical system that undergoes transitions from one state to another, with probabilities that are dependent on the current state only. Here, we have three models, M1, M2, and M3, which represent the states of the Markov chain. The transition probabilities define how likely it is to move from one state to another.

To construct this Markov chain, we set up a probability matrix P where the rows represent the current state, and the columns represent the next state. For the given model:

If the current model is M1, we have transition probabilities of 0.2 to M2 and 0.15 to M3.

If the current model is M2, we have transition probabilities of 0.6 to M1 and 0.25 to M3.

If the current model is M3, we have transition probabilities of 0.5 to M1 and 0.1 to M2.

Since the probabilities must add up to 1, the probability of remaining in the same state is 1 minus the sum of transition probabilities to other states. With these probabilities, we can fill in the transition matrix P:

P(M2|M1) = 0.2, P(M3|M1) = 0.15, P(M1|M1) = 0.65.

P(M1|M2) = 0.6, P(M3|M2) = 0.25, P(M2|M2) = 0.15.

P(M1|M3) = 0.5, P(M2|M3) = 0.1, P(M3|M3) = 0.4.

By using this transition matrix, we can analyze the professor's behavior in selecting new computer models over time.

The general solution of the differential equation [tex]\frac{dy}{dx} = \frac{8x}{y}[/tex] using variable separable method is [tex]y^{2}= 8 x^{2} +C[/tex].

If it is possible to write a differential equation by the transportation of terms, in the form f(x) dx = g(y) dy where f(x) is the function of x and g(y) is the function of y, then we say that variables are separable.

The solution is given by:

[tex]\int\ {f(x)} \, dx = \int\ {g(y)} \, dy + c[/tex]

where c is the arbitrary constant.

[tex]\frac{dy}{dx} = \frac{8x}{y} \\\\y\, dy = 8x \,dx\\\\\int\ {y} \, dy = \int\ {8x} \, dx\\\\\frac{y^{2} }{2} = \frac{8x^{2} }{2} + C \\\\y^{2}= 8 x^{2} +C[/tex]

Answer:

the answer is false

Step-by-step explanation:

False, The shapes of the horizontal cross-sections of the cone below are not all congruent.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We are given the statement,

'The shapes of the horizontal cross-sections of the cone are all congruent'.

Now, if we cut the cone horizontally, the cross-sectional shape is a 'circle'.

Further, the radius of the circle vary depending on the position form where the cone is cut i.e.

If cut from the top, the circle is approximately equal to a point.

If cut from the middle, the radius of the circle is less than the radius of the cone.

If cut from the bottom, the radius of the circle is equal to the radius of the cone.

Now, 'two figures are congruent if they overlap each other'.

Since, the circles have different radius, they will not overlap each other.

Thus, all the cross-sections of the cone would not be congruent.

Hence, the given statement is false.

Answer:

The length of c = 18.7 units ⇒ answer (d)

Step-by-step explanation:

In triangle ABC:

∵ measure of angle B = 17° 55'

∵ measure of angle C = 98° 15'

∵ The sum of measures of the interior angles of a triangle is 180°

∴ The measure of angle A = 180 - (17° 55' + 98° 15') = 63° 50'

∵ The length of a = 17 units

* To find the length of c use the sin Rule

- a/sin(A) = b/sin(B) = c/sin(C)

- a is the side opposite to angle A, b is the side opposite

  to angle B and c is the side opposite to angle C

∴ 17/sin(63° 50') = c/sin(98° 15')

* By using cross-multiplication

∴ c = (17 × sin(98° 15')) ÷ sin(63° 50')

∴ c = 18.7 units

∴ The length of c = 18.7 units ⇒ answer (d)

The circumference of a circle is calculated like this:

[tex]c = 2 \times \pi \times r = \pi \times d[/tex]

If the circumference of the circle is 34π, its diameter is 34(cm), therefore its radius is 17(cm).

To find the diameter and radius of a circle when given the circumference, you can use the formulas C = 2πr or C = πd. In this case, the circumference is 34π. The circle's diameter is 34 units, and the radius is 17 units.

To find the diameter and radius of a circle when given the circumference, you can use the formula C = 2πr or C = πd, where C is the circumference, r is the radius, and d is the diameter. In this case, the circumference is given as 34π. Using the formula C = πd, we can substitute the value of the circumference and solve for the diameter:

34π = πd

Dividing both sides of the equation by π, we get:

34 = d

So, the diameter of the circle is 34 units. To find the radius, we can use the formula r = d/2:

r = 34/2

r = 17

Therefore, the circle's diameter is 34 units, and the radius is 17 units.

Answer:

5 sheets.

Step-by-step explanation:

There are 28 / 4 = 7 students in one group.

Each group was given 35 sheets of paper so each student got 35/7

= 5 sheets.

Each student will get 5 sheets of paper. This is found by dividing the total number of sheets per group (35) by the number of students in each group (7).

To solve the problem, we first need to understand that Mr. Lubec's 28 students are divided into four equal groups. We divide 28 by 4 to determine how many students are in each group, which is 7 students. Mr. Lubec gave each group 35 sheets of paper. To find out how many sheets of paper each student receives, we divide the total number of sheets per group by the number of students in each group.

So, we calculate 35 sheets ÷ 7 students, which equals 5 sheets of paper per student. Therefore, each student will get 5 sheets of paper.

Answer:

Step-by-step explanation:

Absolute minimum is where, in the infinite domain of f(x), the least value the function is the absolute minimum.

However, the local minimum is only a specific interval on the domain of f(x) where the lowest value is, but only in that interval.

So, usually, this comes up when you're dealing with 1st and 2nd derivatives. The first derivative tells you where local max and mins are, where the 2nd derivative tells you if the concavity is up or down.

An absolute minimum is the lowest point on the entire domain of a function, while a local minimum is the lowest point in a specific interval or neighborhood around a point on the graph.

An absolute minimum and a local minimum are both points on a graph where the function reaches its lowest value, but there are key differences between them.

An absolute minimum is the lowest point on the entire domain of the function. In other words, it is the smallest function value among all the points.

On the other hand, a local minimum is the lowest point in a specific interval or neighborhood around a particular point on the graph. It is possible for a function to have multiple local minima.

1 Gallon = 4 quarts of milk

1/4 = 1 quart of milk

4 quarts of milk = 8 pints of milk

8/6 = 1.33 pints of milk

Each friend has 1.33 pints of milk

Each friend will get 1/24 of a gallon of milk.

To find out how much milk each friend will have, we need to divide 1/4 of a gallon by 6.
how much milk each friend gets,
(1/4) ÷ 6
(1/4) × (1/6)
= 1/24

Therefore, each friend gets 1/24 of a gallon of milk.

In conclusion, if 1/4 of a gallon of milk is shared equally among 6 friends, each friend will have 1/24 of a gallon of milk.

The balance at the end of six years will be approximately $899.48.

Explanation:

To calculate the balance at the end of six years, we can use the formula for compound interest:

[tex]A = P(1 + r/n)^(nt)[/tex]

where A is the final amount, P is the principal amount (initial investment), r is the interest rate, n is the number of times the interest is compounded per year, and t is the number of years.

Plugging in the values, we have:

[tex]A = 634(1 + 0.06/1)^(1*6)[/tex]

[tex]= 634(1.06)^6[/tex]

= 634(1.418519)

Correct answer is B.) Her monthly average would have increased by $19.57.

Step-by-step explanation:

The true statement about her average monthly tip is (b) Her monthly average would have increased by $19.57.

The average of a dataset is simply the mean value or the expected value of the dataset

The table is given as:

June       July         August       September     October     November

$133.45   $235.31    $239.45     $258.87         $298.45     $115.67

For the 6 months, the average is:

Average = (133.45+235.31+239.45+258.87+298.45+115.67)/6

Average = 213.53

For the 5 months (i.e. exclusive of December), the average is:

Average = (133.45+235.31+239.45+258.87+298.45)/5

Average = 233.10

The 5 months average is greater than the 6 months average.

And the difference (d) is:

d = 233.10 - 213.53

The expression for the total number of dice in b boxes for both a board game, which comes with 2 dice, and a card game, which comes with 3 dice, is 5b. This is calculated by adding the number of dice in each box (2b for the board game and 3b for the card game).

The question is asking for an expression that shows the total number of dice in b boxes of the board game and the card game. The board game comes with 2 dice and the card game comes with 3 dice.

To get the total number of dice, one needs to multiply the number of dice in each type of game by the number of boxes, b, and then add the results together.

The total number of dice in the board game is 2b and the total number of dice in the card game is 3b. The sum of these two amounts gives the total number of dice. So the expression for the total number of dice in b boxes of both games is 2b + 3b, which simplifies to 5b.
