Quadrilateral BIRD is inscribed in circle O.
What is the measure of angle D?

The value of 's' is calculated using the formula s = re, where e is the angle in radians and r is the radius in meters, which can also be determined statistically.

The value of s in the given physics problem represents the distance between two objects separated by an angle, when they are a certain distance r apart. According to the information and by using the formula s = re, where e is the angle in radians and r is the radius in meters (converted from millimeters), we can substitute the known values to find s. Since S = 80×109 N/m² is the shear modulus and given the small value of Kåp, we assume that s will be significantly small compared to 0.040. Additionally, the value of s can also be found using statistical methods, as indicated by a computer or calculator output showing s = 16.4 as the standard deviation in a set of residuals.

Step-by-step explanation:

Final answer:

The function f(x) = 3x^2 + 2x + 4 has no real zeros because the discriminant (b^2 - 4ac) is negative, indicating that the roots of the quadratic equation are complex.

Explanation:

The question asks us to identify the real zeros of the function f(x) = 3x2 + 2x + 4. To find the real zeros, we look for values of x that make f(x) equal to zero. We can approach this by attempting to solve the quadratic equation 3x2 + 2x + 4 = 0 using the quadratic formula, which is x = [-b ± √(b2 - 4ac)]/(2a), where a = 3, b = 2, and c = 4.

Inserting these values into the formula, we get:

x = [-2 ± √((2)2 - 4*3*4)]/(2*3)

x = [-2 ± √(4 - 48)]/(6)

x = [-2 ± √(-44)]/(6)

Since the part under the square root (√(-44)) is negative, this indicates that the solutions for x are complex, not real. Therefore, the equation 3x2 + 2x + 4 has no real solutions.

Answer:

D

Step-by-step explanation:

The area (A) of a triangle is calculated using the formula

A= [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

here b = 8 and h = 2, so

A= 0.5 × 8 × 2 = 8 units² → D

MN is 63 mm.

Since triangles MPQ and NQP are similar, we have the following

proportion:

[tex]\frac{MQ}{NP} = \frac{QP}{MN}[/tex]

Substituting the given values, we have:

[tex]\frac{30}{10} = \frac{21}{MN}[/tex]

Solving for MN, we get:

[tex]MN = \frac{21 \times 30}{10} = 63 mm[/tex]

Therefore, MN is 63 mm.

The verbal statement 'three times a number increased by 8 is at most 40 more than the number' is expressed as the inequality 3x + 8 ≤ x + 40 in mathematical terms. This inequality simplifies to x ≤ 16, indicating that the original number must be 16 or less.

The question involves translating a verbal statement into a mathematical inequality. The phrase 'three times a number increased by 8 is at most 40 more than the number' can be represented algebraically. Begin by letting the variable 'x' represent the unknown number. The phrase 'three times a number' translates to '3x', 'increased by 8' means we add 8, and 'is at most' indicates that the expression is less than or equal to something. '40 more than the number' is translated to 'x + 40'. Combining these elements, we have the inequality 3x + 8 ≤ x + 40.

To solve this inequality, we would subtract 'x' from both sides to get 2x + 8 ≤ 40, and then subtract 8 from both sides to find 2x ≤ 32. Next, we would divide both sides by 2 to get x ≤ 16. This tells us that the original number must be 16 or any number less than 16 to satisfy the condition described in the question.

Understanding how to translate verbal statements into mathematical expressions and inequalities is a fundamental math skill. Knowing terms such as 'at most' is crucial for setting up the correct inequality. This situation is an application of basic algebra to interpret and solve problems.

17 and 8

Step-by-step explanation:

8 is the shortest board so multiply 8 by 2 add the 1 foot more gives you 17

The greatest common factor between 14 and 24 is 2 because

The factors of 14 that divides 14 without a remainder are 1,2, and 7

The factors of 24 that divides 14 without a remainder are 1,2,3,4,6,8,and 12

Therefore 2 is the greatest factor between 14 and 24.

For this case we have that by definition, the Greatest Common Factor or GFC of two numbers is given by the biggest factor that divides both without leaving residue. We should look for the GFC of 14 and 24.

14: 1,2,7,14

7x10^3 is 3-1/2 times the size of 2x10^3.

Step-by-step explanation:

The highest point of a parabola is at the vertex.

x = -b / (2a)

x = -1 / (2×-0.0023)

x ≈ 217.4

y = (217.4) − 0.0023 (217.4)²

y ≈ 108.7

The horizontal distance can be found when the potato lands (y=0):

0 = x − 0.0023x²

0 = x (1 − 0.0023x)

x = 0, x ≈ 434.8

So the potato reaches a maximum height of 108.7 m and travels a horizontal distance of 434.8 m.

The height point of the trajectory is 217.39 meters and the horizontal distance the potato travels before hitting the ground is 434.78 meters.

To find the height point of the trajectory and the horizontal distance the potato travels before hitting the ground, we can use the equation y=x-0.0023x^2 to represent the trajectory. Since the trajectory is a parabola, the height point corresponds to the vertex of the parabola. To find the vertex, we can use the formula x = -b / (2a), where a = -0.0023 and b = 1. To find the horizontal distance the potato travels before hitting the ground, we need to find the x-intercepts of the parabola, which correspond to the points where y = 0.

First, let's find the height point:

Using the formula x = -b / (2a) and substituting the values, we get:

x = -1 / (2 * (-0.0023)) = 217.39 meters

Now, let's find the horizontal distance:

Setting y = 0 and solving for x, we get:

0 = x - 0.0023x^2

0 = x(1 - 0.0023x)

x = 0 or x = 434.78 meters

Therefore, the height point of the trajectory is 217.39 meters and the horizontal distance the potato travels before hitting the ground is 434.78 meters.

Electrical power is the rate at which the electrical force does work. So what is electrical work? That's the work [tex]W[/tex] that the electrical force do when it moves charges [tex]Q[/tex] across a potential difference [tex]V[/tex]:

W = [tex]V\cdot Q[/tex].

The power is the rate at which the electrical force do the work:

[tex]\displaystyle P = \frac{W}{t} = V \cdot \frac{Q}{t}[/tex].

On the other hand, current [tex]I[/tex] is the charge through a cross-section of the circuit in unit time. By the definition of current:

[tex]\displaystyle\frac{Q}{t} = I[/tex].

[tex]\displaystyle P =V \cdot \frac{Q}{t} = V\cdot I[/tex].

Consider Ohm's Law:

[tex]V = I \cdot R[/tex].

Therefore

[tex]\displaystyle P = V\cdot I = (I \cdot R) \cdot I = I^{2}\cdot R[/tex].

cos x + i sin x in the range 0 to 2pi will be unique so false.

Complex numbers exist the numbers that exist expressed in the form of a+ib where, a, and b are real numbers, and 'i' exists an imaginary number named “iota”. The value of i = (√-1).

The abbreviated polar form of a complex number exists z = rcis θ, where r = √(x2 + y2) and θ = tan-1 (y/x).

The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number in the distribution from the highest.

The range in statistics for a given data set is the difference between the highest and lowest values. For example, if the given data set is {2,5,8,10,3}, then the range will be 10 – 2 = 8. Thus, the range could also be defined as the difference between the highest observation and lowest observation.

Hence, cos x + i sin x in the range 0 to 2pi will be unique so false.

Answer:

Radius of the cone is 6 unit.

Step-by-step explanation:

Given:

Lateral Surface Area of Cone, LSA = 100π unit²

Total Surface Area of cone, TSA = 136π unit²

Let, r be the radius of cone.

According to the question,

Total Surface area = lateral surface area + Area of circle

136π = 100π + πr²

πr² = 36π

r² = 36

r = 6

Therefore, Radius of the cone is 6 unit.

The radius of the cone is 6 units.

To solve for the radius of the cone, we need to use two formulas: the lateral area (LA) and the total surface area (TSA) of a cone. The given values are:

We use the following formulas:

From the given values:

From the first equation, we can express l in terms of r:

l = 100 / r

Substitute l in the second equation:

136 = r² + r(100 / r)
=> 136 = r² + 100

Rearrange the equation to solve for r:

r² = 136 - 100
=> r² = 36
=> r = √36
=> r = 6.

Answer:

None of the statements are true​

Step-by-step explanation:

Given statements are:

I. The difference between -14 and -8.3 is positive.

II. -14 + 8.3 has the same value as the difference between -1.4 and -8.3.

III. The between -8.3 and -14 has the same value as the difference between -1.4 and -8.3.

Test for statement (I).

difference = -14-(-8.3) = -14+8.3 = -5.7

which is negative so statement I is FALSE.

Test for statement (II).

-14+8.3 = 5.7

difference = -14-(-8.3) = -14+8.3 = -5.7

which are different so statement II is FALSE.

Test for statement (III).

difference = -8.3-(-14) = -8.3+14 = 5.7

which is different than difference value -5.7 for statement I.

so statement III is FALSE.
