The zoo is building a new polar bear exhibit, and wants to put a semi-circular window in the concrete wall of the swimming tank. If the semi-circle has diameter 70 centimeters, and the bottom of the window is at a depth of 2.5 meters, find the hydrostatic force on the window.

Answers

Answer 1

The hydrostatic force on the window is approximately 47,481 Newtons.

We can use the formula for hydrostatic force, which is:

F = ρghA

where F is the hydrostatic force, ρ is the density of the fluid (water in this case), g is the acceleration due to gravity, h is the depth of the window, and A is the area of the window.

First, we need to find the area of the window. Since the window is a semi-circle with diameter 70 centimeters, the radius is 35 centimeters, and the area is:

A = (π/2)r^2

= (π/2)(35 cm)^2

= 1225π/2 cm^2

Next, we need to convert the depth of the window to meters:

h = 2.5 m

We also need the density of water, which is approximately:

ρ = 1000 kg/m^3

Finally, we need the acceleration due to gravity, which we can assume is:

g = 9.8 m/s^2

Now we can plug these values into the formula:

F = ρghA

= (1000 kg/m^3)(9.8 m/s^2)(2.5 m)(1225π/2 cm^2)

≈ 47,481 N

Therefore, the hydrostatic force on the window is approximately 47,481 Newtons.

Find the sum.

Answers

Answer:

1540

Step-by-step explanation:

This is an arithmetic progression.

a = first term = 10

Common difference = d = second term - first term

                                         = 12 - 10

                                     d  = 2

Last term = l = 78

First we have to find how many terms are there in the sequence using the formula:  l = a + (n-1)*d

                   78 = 10 + (n -1) * 2

               78 -10 = (n -1)*2

                     68 = (n -1) *2

               68 ÷2 =  n -1

                      34 = n - 1

                 34 + 1 = n

in order to solve the following system of equations by subtraction, which of the following could you do before subtracting the equations so that one variable will be eliminated when you subtract them?
4x-2y=7
3x-3y=15

Answers

The following system of equation can be solved by first substituting the dependent variable in the other equation . The solution yields x = -1.5 and y = 6.5 .

What is the solution of the given system of equation ?

The two equations are given as -

4x-2y=7

3x-3y=15

First substituting the value of x from the first equation and then putting that value in the second equation for the following system of equation.

From first equation,

⇒ 4x = 7 + 2y

∴  x = (7 + 2y)/4

Putting this value of x in second equation,

⇒ 3*(7 + 2y)/4 - 3y = 15

⇒ 3*(7 + 2y) - 12y = 60

⇒ 21 + 6y - 12y = 60

⇒ -6y = 39

∴  y = -6.5

∴ x = (7 + 2y)/4 = -1.5

Thus x = -1.5 and y = -6.5

Therefore, the following system of equation can be solved by first substituting the dependent variable in the other equation . The solution yields x = -1.5 and y = 6.5 .

Explain why Rolle's Theorem does not apply to the function even though there exist a and b such that f(a)

Answers

Rolle's Theorem does not apply to the function because there are points on the interval (a,b) where f is not differentiable.

Given the function is [tex]f(x)=\sqrt{(2-x^{\frac{2}{3}})^{3}}[/tex]  and the Rolle's Theorem does not apply to the function.

Rolle's theorem is used to determine if a function is continuous and also differentiable.

The condition for Rolle's theorem to be true as:

f(a)=f(b)f(x) must be continuous in [a,b].f(x) must be differentiable in (a,b).

To apply the Rolle’s Theorem we need to have function that is differentiable on the given open interval.

If we look closely at the given function we can see that the first derivative of the given function is:

[tex]\begin{aligned}f(x)&=\sqrt{(2-x^{\frac{2}{3}})^3}\\ f(x)&=(2-x^{\frac{2}{3}})^{\frac{3}{2}}\\ f'(x)&=\frac{3}{2}(2-x^{\frac{2}{3}})^{\frac{1}{2}}\cdot \frac{2}{3}\cdot (-x)^{\frac{1}{3}}\\ f'(x)&=\frac{-\sqrt{2-x^{\frac{2}{3}}}}{\sqrt[3]{x}}\end[/tex]

From this point of view we can see that the given function is not defined for x=0.

Hence, all the assumptions are not satisfied we can reach a conclusion that we cannot apply the Rolle's Theorem.

10% every day is equal to 100/10.

So they would each contribute 16.25 percent per day as a group.

then for six days,

97.50% of the work has been finished, in other words.

The amount of work left is now 100-97.5 = 2.5.

Answer:

7.7 km

Explanation:

Use cosine rule as here given two sides and one angle.

Cosine rule states:

a² = b² + c² - 2bc cos(A)

While solving, treat a = 7.5 km as to that opposite angle is given of 68°

then b = missing side, c = 5.2 km, A = 68°

Applying rule:

7.5² = b² + 5.2² - 2(b)(5.2) cos(68)

56.25 = b² + 27.04 - 3.8959b

56.25 - 27.04 = b² - 3.8959b

b² - 3.8959b = 29.21

b² - 3.8959b - 29.21 = 0

apply quadratic equation, Here [a = 1, b = - 3.8959, c = -29.21]

[tex]\sf b = \dfrac{ -b \pm \sqrt{b^2 - 4ac}}{2a} \quad\:when \:\ ax^2 + bx + c = 0[/tex]

[tex]\sf b = \dfrac{ -(-3.8959) \pm \sqrt{(-3.8959)^2 - 4(1)(-29.21)}}{2(1)}[/tex]

[tex]\sf b = 7.69 291 \quad or \quad b = -3.797[/tex]

[tex]\sf b = 7.7 \quad (rounded \ to \ nearest \ tenth)[/tex]

As length cannot be negative. Hence the value of b is only 7.7 km

The answer is 7.7 km.

Let's apply the Cosine Law in this situation.

a² = b² + c² - 2bc cos(A)

Now, substitute the values based on the given diagram.

(7.5)² = b² + (5.2)² - 2(b)(5.2)(cos 68°)56.25 =  b² + 27.04 - 3.896bb² - 3.896b - 29.21 = 0

Here, using the Quadratic Equation, we can solve :

b = 3.896 ± √(3.896)² - 4(1)(-29.21) / 2b = 3.896 ± √15.178816 + 116.84 / 2b = 3.896 ± √132.018816 / 2b = 3.896 + 11.49 / 2b = 7.7 km

When bowling, the scoring rule for a spare is 10 points and then the points scored in the next delivery. Group of answer choices True False

The given statement is True for the scoring rule in bowling.

Scoring Rule in Bowling

The number of frames in a game of bowling is ten. According to the scoring rule in bowling, the bowler will have two opportunities to use their bowling ball to remove as many pins as they can throughout each frame.

Every bowler will complete their frame in a predefined order before the next frame starts in games with more than one bowler, which is typical.

Rule for Spare

A bowler is given a strike if they can remove all 10 pins with their first ball. A spare is achieved when the bowler uses both of the two balls in a frame to remove all 10 pins.

Depending on whether the next two balls (for a strike) or the next ball (for a goal) are scored, bonus points are given for both of these (for a spare), as per the scoring rule.

The value of z-score for a score that is three standard deviations above the mean is 3.

In this question,

A z-score measures exactly how many standard deviations a data point is above or below the mean. It allows us to calculate the probability of a score occurring within our normal distribution and enables us to compare two scores that are from different normal distributions.

Let x be the score

let μ be the mean and

let σ be the standard deviations

Now, x =  μ + 3σ

The formula of z-score is

[tex]z_{score} = \frac{x-\mu}{\sigma}[/tex]

⇒ [tex]z_{score} = \frac{\mu + 3\sigma -\mu}{\sigma}[/tex]

⇒ [tex]z_{score} = \frac{ 3\sigma }{\sigma}[/tex]

⇒ [tex]z_{score} = 3[/tex]

Hence we can conclude that the value of z-score for a score that is three standard deviations above the mean is 3.

The length and width of the rectangle with an area of 120 units² are 12 units and 10 units respectively.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the width, hence:

length = x + 2

The area of a rectangle is the product of its length and its width.

Area = length * width

Area = x(x + 2)

120 = x² + 2x

x² + 2x - 120 = 0

x = 10, length = 10 + 2 = 12

The length and width of the rectangle with an area of 120 units² are 12 units and 10 units respectively.

Rewrite the expression in the form y^n.
(y^2)^3 =

Answers

Answer:

[tex]y^6[/tex]

Step-by-step explanation:

So there is an exponent identity that states: [tex](x^b)^a = x^{a*b}[/tex] which means this question becomes: [tex](y^2)^3 = y^{2*3} = y^6[/tex].

Just so you completely understand why this works, it might help to express y^2, as what it truly represents: [tex]y^2=y*y[/tex]. So using this definition we can substitute it into the equation so it becomes: [tex](y*y)^3[/tex]. Now let's use the definition of exponents like we just did with the y, to redefine this in terms of multiplication: [tex](y*y)^3 = (y * y) * (y * y) * (y * y)[/tex]. We can just multiply all these out, and we get: [tex]y * y * y * y * y * y =y^6[/tex].

To make it a bit more general when we have the exponent: [tex]x^b[/tex] it can be expressed as: [tex](x*x*x...\text{ b amount of times})[/tex] now when we raise it to the power of a. we get: [tex](x * x * x...\text{ b amount of times})^a[/tex] which can further be rewritten using the definition of an exponent to become the equation: [tex](x*x*x\text... \text{ b amount of times}) * (x * x * x...\text{ b amount of times})...\text{ a amount of times}[/tex] which just simplifies to: [tex]x*x*x*x...\text{ a times b amount of times}[/tex]. Hopefully this makes the identity a bit more understandable

Fyodor and his three sons, Ivan, Dmitri and Alyosha, are standing exactly on the corners of a rectangular room. Fyodor is $3$ meters from Dmitri and $5$ meters from Ivan. What is the minimum possible distance that Fyodor could be from Alyosha, in meters

Answers

The minimum possible distance that Fyodor could be from Alyosha is 4 meters.

Given Information and Deduction

It is given that Fyodor is 3 meters in distance away from Dmitri and 5 meters from Ivan.

Now, since we know that the longest side of a right angle triangle formed by the dividing the rectangular room into two parts using a diagonal is the hypotenuse. Thus, if we want to find the minimum possible distance between Fyodor and Alyosha, we will have to assume that Ivan is standing diagonally opposite to Fyodor, as shown in the figure below.

Calculating the Minimum Distance

According to Pythagoras Theorem,

(hypotenuse)² = (base)² + (perpendicular)²

Here, the hypotenuse is the distance between Fyodor and Ivan.

Perpendicular and the base are the distances between Fyodor and Dmitri, and Fyodor and Alyosha respectively.

⇒ base = √(hypotenuse)² -(perpendicular)²

⇒ base = √(5)²-(3)²

⇒ base = √(25-9)

⇒ base = √16

⇒ base = 4 meters

Therefore, the minimum possible distance between Fyodor and Alyosha is 4 meters.
