The triangles on the front of the Louvre Pyramid are all isosceles triangles.

The building acts as a visible reminder of the importance of the museum's Egyptian Antiquities collections.

The primary entry point to the Louvre is the I.M. Pei Pyramid, which is situated in the courtyard. The building acts as a visible reminder of the importance of the museum's Egyptian Antiquities collections.

A graph on the right AB = 35 meters {Given}

AE = 32 meters {Given}

Because AE = BE = 32 meters

So <EAB = <ABE By measure,

<EAB=663°

So <ABE=663°.

So <AEB = 180° - LEAB-LABE.

= 180°-66.3° - 66.3° =47.4°

So, ΔABE is an isosceles triangle.

Answer:

The answer is A: 2500 pi

Step-by-step explanation:

To find the volume of a cylinder use the formula:

π[tex]r^{2}h[/tex]

So we know that the diameter is 10, so radius must be 10/2 or 5.

Now we square 5 to get 25.

Multiply 25 times height which is 100.

So 25 x 100 is equal to 2500

Now multiply the pi or just let it stay like that

The answer is 2500π.

I believe the expression you provided is:

(log(x) + 4x^3) / x

To find the discontinuities of this expression, we need to identify any values of x that would cause the expression to be undefined. These values are called the discontinuities.

There are two types of discontinuities to look for:

Removable discontinuities: These occur when a function is undefined at a certain point but can be made continuous by redefining the function at that point.

Non-removable discontinuities: These occur when a function is undefined at a certain point and cannot be made continuous by redefining the function at that point.

To find the discontinuities of the given expression, we need to look for values of x that would make the denominator equal to zero, as this would result in a non-removable discontinuity.

So we solve the equation:

x = 0

This means that x cannot be equal to zero, as it would make the denominator zero and the expression undefined.

Therefore, the only discontinuity of the expression is at x = 0.

Note that there are no removable discontinuities in this expression, as the expression is continuous everywhere except at x = 0.

Step-by-step explanation:

The formula for Py(Y) = ∑P y,z (y, z) for z ∈ Z is consistent with the third Axiom of the probability measure.

The third Axiom of the probability measure states that the sum of probabilities of all possible outcomes of an event is equal to 1. In the context of two discrete random variables Y and Z, this axiom means that the sum of probabilities of all possible pairs (y, z) is equal to 1.

The formula PY(Y) = ∑P y,z (y, z) for z ∈ Z is related to this axiom because it represents the probability of the random variable Y taking on a specific value y, regardless of the value of Z. The summation is taken over all possible values of z in Z, and P y,z (y, z) represents the joint probability of Y and Z taking on the specific values (y, z).

Since the sum of probabilities of all possible pairs (y, z) is equal to 1, the sum of probabilities of all possible values of Y, represented by PY(Y), must also be equal to 1.

Therefore, the formula for PY(Y) is consistent with the third Axiom of the probability measure.

The 98% confidence interval for the mean amount of money spent per month on home maintenance by all homeowners is (62.49,69.51). So, the Lower and Upper end point are 62.49, 69.51 respectively.

We have a survey of 53 randomly selected homeowners. So,

Sample size, n = 53

Mean spend of home maintenance, μ

The answer is 8.6+(-6.1). This is because addition and subtraction are inverse operations.

Subtraction that involves taking one number away from another. It is the inverse of addition and is represented by the minus sign (-).

This means that when you add two numbers and then subtract the same amount, the result is the same as just adding the two numbers.

Similarly, when you subtract two numbers and then add the same amount, the result is the same as just subtracting the two numbers.

Therefore, 6.1+8.6 is equivalent to 8.6+(-6.1).

Using mathematical notation, we can represent this expression as 6.1+8.6 = 8.6+(-6.1).

To add and subtract the numbers, we can use the traditional column method.

First, we write out 6.1+8.6 as 6.1 - (-8.6). Then, we add the numbers in each column, starting with the ones column:

Ones column: 1+6=7

Tens column: 8-8=0

And our answer is 7,0. We can also write this as 8.6+(-6.1) to show that the two expressions are equivalent.

A rectangle is a quadrilateral that has two pairs of parallel and congruent opposite sides and four right angles (90 degree angles). A rectangle is a special case of a parallelogram.

1. ∠A ≅ ∠D

The above statement is always true for rectangles. In Euclidean geometry, by the definition of a rectangle, the four interior angles are right angles, which means m∠A = m∠B = m∠C = m∠D = 90°, therefore; ∠A ≅ ∠B ≅ ∠C ≅ ∠D.

The statement; ∠A ≅ ∠D, according to the above expression and the transitive property of congruence, is always true.

Answer:

Step-by-step explanation:

An irrational number is a number that cannot be expressed as a simple fraction. Therefore 0.6263646 is irrational.

Let's assume that the width of the rectangular poster is "x".

According to the problem, the length is 8 more inches than half the width, which can be expressed as:

length = (1/2)x + 8

The area of the poster is given as 40 square inches, so we can write the equation:

Area = length × width

Substituting the values of length and width in terms of "x", we get:

40 = ((1/2)x + 8) × x

Simplifying the equation:

40 = (x^2)/2 + 8x

Multiplying both sides by 2 to eliminate the fraction:

80 = x^2 + 16x

Rearranging the equation in standard quadratic form:

x^2 + 16x - 80 = 0

Using the quadratic formula:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 1, b = 16, and c = -80

x = (-16 ± sqrt(16^2 - 4(1)(-80))) / 2(1)

x = (-16 ± sqrt(736)) / 2

x = (-16 ± 8sqrt(9)) / 2

We can discard the negative solution since width cannot be negative:

x = (-16 + 24) / 2

x = 4

So, the width of the poster is 4 inches.

Using the equation for length:

length = (1/2)x + 8

length = (1/2)(4) + 8

length = 2 + 8

length = 10

Therefore, the dimensions of the poster are 10 inches by 4 inches.

Let us assume that the variables:

d = distance

t = time (in seconds)

~

The question assumes that the horse will move 15 meters every second. Therefore:

d = 15t

IF:

t (time) = 1 seconds, then:

d = 15(1)

d = 15

IF:

t (time) = 2 seconds, then:

d = 15(2)

d = 30

IF:

t (time) = 5 seconds, then:

d = 15(5)

d = 75

As you can see, the graphed numbers are much more larger than the numbers that you have already written, and so it is best to change the numbers. Generally the y-axis is used for time (in this case, seconds), whlie the x-axis is used for distance (in this case, meters).

(i) The domain of f(x) is all real numbers, since there are no restrictions on the input variable x.

(ii) We have:

f(x) = x^4 - 2x^3

f'(x) = 4x^3 - 6x^2

f''(x) = 12x^2 - 12x

(iii) To find the critical points, we need to solve the equation f'(x) = 0:

4x^3 - 6x^2 = 0

2x^2(2x - 3) = 0

x = 0 or x = 3/2

So the critical points are (0,0) and (3/2, -27/16).

(iv) To determine where f(x) is increasing or decreasing, we need to examine the sign of f'(x) on different intervals. We can make a sign chart for f'(x):

| x | -∞ | 0 | 3/2 | +∞ |

|---------|--------|-------|-------|--------|

| f'(x) | - | 0 | + | + |

From the sign chart, we see that f(x) is decreasing on the interval (-∞, 0) and increasing on the interval (0, 3/2) and (3/2, +∞).

(v) To find the relative extrema, we need to examine the sign of f'(x) around the critical points. We can make a table:

| x | 0- | 0+ | 3/2- | 3/2+ |

|---------|-------|-------|-------|-------|

| f'(x) | - | + | - | + |

| f(x) | 0 | 0 | -27/16| -27/16|

From this table, we see that f(x) has a relative minimum of -27/16 at x = 3/2, and no relative maximum or minimum at x = 0.

(vi) To find the intervals where f(x) is concave up or concave down, we need to examine the sign of f''(x) on different intervals.

We can make a sign chart for f''(x):

| x | -∞ | 0 | 1 | +∞ |

|---------|--------|-------|------|--------|

| f''(x) | + | - | + | + |

From the sign chart, we see that f(x) is concave down on the interval (-∞, 0) and concave up on the intervals (0, 3/2) and (3/2, +∞).

(vii) To find the points of inflection, we need to solve the equation f''(x) = 0:

12x^2 - 12x = 0

12x(x - 1) = 0

x = 0 or x = 1

So the points of inflection are (0,0) and (1, -1).

(viii) To sketch the graph of f(x), we can use the information we have gathered so far.

At x = 0, f(x) has a relative minimum of 0 and is concave down. At x = 3/2, f(x) has a relative minimum of -27/16 and is concave up. The point (1, -1) is a point of inflection.

Based on this information, we can sketch a graph of f(x) that looks like this:

```

|

|

--------o------------o-------

0 3/2 x-axis

```

The graph is a "U" shape that opens upward, with a relative minimum at (3/2, -27/16) and a point of inflection at (1, -1).

For function f(t) = 1.25^t, it is an exponential growth.

The percent rate of change per unit t is found by taking the derivative of the function:

f'(t) = ln(1.25) * 1.25^t ≈ 9.2%

Since f'(t) is positive, the function represents exponential growth.

For function g(t)=5^-t:

The percent rate of change per unit t is found by taking the derivative of the function:

g'(t) = -ln(5) * 5^-t ≈ -13.9%

Since g'(t) is negative, the function represents exponential decay.

For function h(t) = 1.20(t/11):

The percent rate of change per unit t is found by taking the derivative of the function:

h'(t) = 1.20/11 ≈ 10.9%

Since h'(t) is positive, the function represents exponential growth.

For function k(t) = 0.63t:

The percent rate of change per unit t is found by taking the derivative of the function:

k'(t) = 0.63 ≈ 63.0%

Since k'(t) is positive, the function represents exponential growth.

After answering the provided question, we can conclude that Therefore, circle the length of the minor arc AB is approximately 50.9 cm.

A circle appears to be an a double component that is defined as the collection of all points in a jet that are equidistant out from hub. A circle is typically depicted with a capital "O" for the centre and a bottom end "r" for the radius, which represents the distance from where it started to any point on the circle. The formula 2r gives the girth (the distance from the center of the circle), where (pi) seems to be a proportionality steady roughly equal to 3.14159. The formula r2 computes the circumference of a circle, which is the quantity of space inside the circle. To calculate the length of the minor arc AB, we need to first find the central angle that it subtends.

C = 2πr

r = C/(2π)

r = 65/(2π) ≈ 10.34 cm

angle = (arc length / radius) x (180/π)

ADB = 360° - AOB

ADB = 360° - 72° = 288°

angle ADB = (arc length AB / 10.34) x (180/π) = 288°

arc length AB = (288° x 10.34 cm x π) / 180 ≈ 50.9 cm

Therefore, the length of the minor arc AB is approximately 50.9 cm.

Answer:

There are 32 apples in the bag.

Step-by-step explanation:

To find the number of apples in the bag, we can use the formula:

number of apples = total mass of apples / average mass of each apple

Given that the bag of apples has a mass of 4 kg, and the average mass of each apple is 1/8 kg, we can substitute these values into the formula to get:

number of apples = 4 kg / (1/8) kg/apple

Simplifying the right-hand side by dividing 4 kg by (1/8) kg/apple, we get:

number of apples = 4 kg * 8/apple = 32 apples

Therefore, there are 32 apples in the bag.

Answer:

Step-by-step explanation:

It is simple by averaging formula as follows
Total mass/average mass = Total apples
4/(1/8)= 32 Apples
