The measure of the angle ∠DBC, m∠DBC, found by writing an equation based on the angle addition postulate is m∠DBC = 30°

What is an equation?

An equation consists of two expressions that are specified as being equivalent, by joining them by an equals to '=' sign.

The specified information are;

m∠ABD = (3·x+ 15)° and m∠DBC = (2·x)°, m∠ABC = 90°

The angle addition postulate indicates that we get;

m∠ABC = m∠ABD + m∠DBC

m∠ABC = 90° = (3·x+ 15)°  + (2·x)° (substitution property)

90° = (3·x+ 15)°  + (2·x)°  = (5·x+ 15)°

(5·x + 15)° = 90°

5·x = 90° - 15° = 75°

5·x = 75°

x = 75°/5 = 15°

x = 15°

m∠DBC = 2·x

Therefore, m∠DBC = 2 × 15° = 30°

m∠DBC = 30°

What quantity of 62% acetic acid solution must be mixed with a 19% acetic acid solution to produce 334. 78 mL of 47% solution?

Answers

x = 217.9927  = amount of mL of the 62% acid solution

y = 116.7873 = amount in mL of the 19% acid solution

This can be solved using a system of two equations and two variables.  

Let x = amount of mL of the 62% acid solution

Let y = amount in mL of the 19% acid solution

We know the total mL of the mixture of the two solutions is 600 mL,

so x + y = 334.78    ..... eq(1)

62% of solution x is acid which can be written as 0.62x and similarly acid from the second solution can be written as 0.19y. We know that 47% of the 334.78 mL solution will be acid or 0.47(334.78).

The acid in the mixture solution comes from the acid in solution x and solution y. So 0.62 x + 0.19 y = 0.47 (334.78)      ... eq(2)

from equation (1)

x = 334.78-y

So, x = 217.9927

  y = 116.7873.

what is the volume of the solid generated when the region in the first quadrant bounded by the graph of y=44−x2−−−−−√ and the x- and y-axes is revolved about the y-axis?

Answers

The volume of the solid generated is [tex]\pi (2/3) (44)^{3/2}.[/tex]

We have,

To find the volume of the solid generated by revolving the region in the first quadrant bounded by the graph of y = √(44 - x²) and the x- and y-axes about the y-axis, we can use the method of cylindrical shells.

The volume can be calculated using the following integral:

V = ∫[a,b] 2πx f(x) dx

where [a, b] is the interval of x-values that defines the region in the first quadrant.

In this case, the curve y = √(44 - x²) intersects the x-axis when y = 0, which gives us:

0 = √(44 - x²)

Squaring both sides and solving for x, we get:

x² = 44

x = ±√44

Since we're considering the region in the first quadrant, we take the positive square root:

x = √44 = 2√11

Now we can set up the integral:

V = ∫[0, 2√11] 2πx (√(44 - x²)) dx

Simplifying the integrand:

V = 2π ∫[0, 2√11] x (√(44 - x²)) dx

To evaluate this integral, we can make the substitution u = 44 - x²,

du = -2x dx:

V = 2π ∫[0, 44] (√u) (-du/2)

V = -π ∫[0, 44] (√u) du

Integrating:

V = -π [2/3 u^(3/2)] [0, 44]

V = -π [2/3 (44)^(3/2) - 0^(3/2)]

V = -π (2/3) (44)^(3/2)

Finally, taking the absolute value and simplifying:

V = π (2/3) (44)^(3/2)

So, the volume of the solid generated is π (2/3) (44)^(3/2).

Thus,

The volume of the solid generated is [tex]\pi (2/3) (44)^{3/2}.[/tex]

Answer:

The store would need to sell 40 bikes to break even.

Step-by-step explanation:

In order to break even the store needs to make $4000 a month. They spend $50 per bike and sell them for $150, an easy equation to get their profit per bike is to subtract how .uch they pay for a bike from how much they make per bike which is $150-50=$100. So now we just need to divide $4000 by $100 to find out how many bikes they need to sell. $4000÷$100=40.

The given equation e(x)=f(x)f(-x) is an even function since e(x)=e(-x) and f(x)^2=f(-x)^2.

let f(x) be a function with domain double-struck r. (a) show that e(x) = f(x) f(−x) is an even function. (simplify your answers completely.) e(x) = f(x) f(−x) = f(x) f(x) = f(x)^2 e(x) = f(x)^2

e(x) = e(-x) Therefore, e(x) is an even function.

(-x) is an even function, we need to show that e(x)=e(-x).

We start by replacing -x with x in the equation:

e(x)=f(x)f(-x)

e(x)=f(x)f(x)

e(x)=f(x)^2

Now, we replace x with -x in the equation:

e(-x)=f(-x)f(-x)

e(-x)=f(-x)^2

Since the left-hand side of both equations are the same (e(x)=e(-x)), and the right-hand sides of both equations are the same (f(x)^2=f(-x)^2), we can conclude that e(x) is an even function.

The sum of independent negative binomial and geometric random variables does not have a closed-form distribution and must be computed numerically.

What is binomial random variable ?

In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own Boolean-valued outcome: success or failure.

Let X be a negative binomial random variable with parameters r and p, and let Y be a geometric random variable with parameter q. The sum Z = X + Y is also a random variable.

The cumulative distribution function (CDF) of Z is given by:

F_Z(z) = P(Z <= z) = P(X + Y <= z) = ∑_{x=0}^{z} P(X = x) * P(Y = z - x)

This expression is a double sum and does not have a closed-form solution, but it can be computed numerically.

Alternatively, the probability mass function (PMF) of Z can be found by counting the number of ways that X and Y can take on their respective values, and summing up their joint probabilities:

f_Z(z) = P(Z = z) = ∑_{x=0}^{z} P(X = x) * P(Y = z - x)

Distance is the sum of an object's movements, regardless of direction. Distance may be defined as the amount of space an item has covered, regardless of its beginning or finishing position.

Let us assume that d means distance and t means time.

When t = 1, d = 2.5

When t = 3, d = 4

d = mt + b

2.5 = m + b [t = 1]

4.0 = 3m + b [t = 2]

1.5 = 2m [subtract]

m = .75 = slope

b = 1.75 = d-intercept

d = .75t + 1.75

The right angle, or 90°, is always one angle.The hypotenuse is the side with the 90° angle opposite.The longest side is always the hypotenuse.The other two inner angles add up to 90 degrees.Base and perpendicular are the names of the other two sides that are close to the right angle.Right-angle triangles have an area that is equal to half of the product of their adjacent sides, hence Area of Right Angle Triangle = 1/2 (Base* Perpendicular).Three such triangles will result if we drop a perpendicular from the right angle to the hypotenuse.The radius of a circle whose circumference includes all three vertices is equal to one-half the length of the hypotenuse.The triangle is known as an isosceles right angled triangle, where the adjacent sides to the 90° are equal in length, if one of the angles is 90° and the other two angles are each equal to 45°.

Let is consider the triangle is a right triangle so the base and height will be 12 mm and 16 mm respectivly.

Now using Pythagoras Theorem :

√(height² + base²) = hypotenuse

⇒√(12²+16²) = √(144+256) = √(400) = 20 mm = hypotenuse.

The triangle that will be formed using the sides 12 mm , 16 mm and 20 mm will be a right trinagle.

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, lian currently pays 640 per month to rent her apartment she has been told by her landlord that her rent will be increasing by 15% next year.

Her rent is now = 640 per month

Since, After a year her rent will increase by 15 %

Thus,

Her rent next year per month = 640(1 + 15%)

Her rent next year per month = 640(1 + 0.15)

Her rent next year per month = 640* 1.15

Her rent next year per month = 736

Therefore, she has to pay $736 per month, next year in rent.

Why do fractions need to have a common denominator before you add or subtract them? Tell me in the comments below

Answers

Explanation: Fractions must have a common denominator to add or subtract because if you think of pieces of a pizza, if you split one pizza into quarters and one into fifths, then each piece won't be the same size, so 1/5 isn't equivalent to 1/4. Therefore, if you subtract or add fractions you need to find a common denominator. One easy way to find a common denominator is list out the multiples of the two (or more) denominators and find the LCM (Least common multiple). Then find the quotient of the LCM divided by the denominator, and multiply that number by the numerator, and you have successfully changed your fraction to an equivalent fraction with a different denominator.

The system of linear equations −3x + 2y = −6 and y equals negative one half times x plus 4 is graphed on a coordinate plane. Approximate the solution to the system.

(−1.5, −3.5)
(−1.5, 4.25)
(2.5, 1.5)
(3.5, 2.25)

Answers

Answer:

D. (3.5, 2.25)

Step-by-step explanation:

A solution to the system is where the two equations intersect.

looking at the graph, we see that the intersection point is between x= 3 and 4, and Y = 2 and 3.

Answer:

(3.5, 2.25)

Step-by-step explanation:

To find the coordinate of the solution to the system of linear equations −3x + 2y = −6 and y = -1/2x + 4, we need to solve the system. One method to do this is substitution. We can solve one of the equations for y, then substitute the expression for y into the other equation. This will give us an equation in terms of x, which we can then solve for x. Then, we can substitute the value of x back into one of the equations to find the corresponding value of y.

Using substitution, we can solve the system as follows:

y = -1/2x + 4

-3x + 2y = -6

Substitute y = -1/2x + 4 into -3x + 2y = -6:

-3x + 2(-1/2x + 4) = -6

-3x + (-x + 8) = -6

-4x + 8 = -6

-4x = -14

x = 3.5

Substitute x = 3.5 into y = -1/2x + 4:

y = -1/2(3.5) + 4

y = 2.25

Therefore, the solution to the system is approximately (3.5, 2.25).

Joseph has a bag filled with 3 red, 3 green, 15 yellow, and 9 purple marbles. Determine P(not red) when choosing one marble from the bag.

10%
30%
50%
90%

Answers

Answer: 90%

Step-by-step explanation: To find the probability of not choosing a red marble, we need to calculate the total number of marbles in the bag and subtract the number of red marbles. The total number of marbles is 3 red + 3 green + 15 yellow + 9 purple = 30. So, the probability of not choosing a red marble is P(not red) = (30 - 3) / 30 = 27 / 30 = 9 / 10=90/100=90%

what will always be a solution to a homogenous set of equations

Answers

Homogeneous systems of linear equations can have either a unique solution or infinitely many solutions, depending on the rank of the matrix representing the system.

A homogeneous set of equations is a set of linear equations that has a trivial solution (that is, a solution consisting of only the zero vector). In other words, if the coefficients of the variables in a set of linear equations are all equal to zero, the set of equations is considered homogeneous.

The trivial solution, that is, the solution in which all variables are equal to zero, will always be a solution to a homogeneous set of equations. This is because, if all coefficients are equal to zero, then each equation in the set will reduce to 0 = 0, which is always true. Thus, the trivial solution is always a solution to a homogeneous set of equations.

In addition to the trivial solution, a homogeneous set of equations may also have non-trivial solutions, which are solutions that are not equal to only the zero vector. To find these non-trivial solutions, we typically use techniques such as Gaussian elimination, row reduction, or the use of matrices and determinants.

It is important to note that homogeneous systems of linear equations can have either a unique solution or infinitely many solutions, depending on the rank of the matrix representing the system.

Therefore, homogeneous systems of linear equations can have either a unique solution or infinitely many solutions, depending on the rank of the matrix representing the system.

for the same frame, complete the free-body diagram of the system abc by adding the forces that act on it.

Answers

The total force acting on the system ABC. The total force is equal to the sum of the force of gravity, normal force, friction force, tension force and applied force (Ftotal = Fg + FN + Ff + T + Fapp).

The force of gravity (Fg) acts on the system in the downward direction. This force is equal to the mass of the body multiplied by the acceleration due to gravity (Fg = mg).

The normal force (FN) is the force that acts perpendicular to the surface on which the body is resting. This force is equal to the weight of the body multiplied by the coefficient of friction between the body and the surface (FN = m * g * μ).

The force of friction (Ff) is the force that acts in the opposite direction of the motion of the body. This force is equal to the coefficient of friction multiplied by the normal force (Ff = μ * FN).

The tension force (T) is the force exerted by a string or a cable on the body. This force is equal to the mass of the body multiplied by the acceleration due to the applied force (T = m * a).

The applied force (Fapp) is the force that is applied to the body by an external force. This force is equal to the mass of the body multiplied by the acceleration due to the applied force (Fapp = m * a).

By combining all of these forces, we can determine the total force acting on the system ABC. The total force is equal to the sum of the force of gravity, normal force, friction force, tension force and applied force (Ftotal = Fg + FN + Ff + T + Fapp).
