Answer:

Choice C    (1/3b)/7 = 25.50

Step-by-step explanation:

1/3 of budget b =(1/3)b

7 bills at $25.50 per bill = 7 x 25.50

Setting both equation to each other we get
(1/3)b = 7 x 25.50

Dividing by 7:
(1/3b)/7 = 25.50

The solution to the differential equation y'' + 4y' + 2y = 4 with zero initial conditions is y(t) = 2e^-2t.

CORRECTION: Given the differential equation: y'' + 4y' + 2y = 4

To solve this differential equation using Laplace transforms, we first need to take the Laplace transform of both sides. The Laplace transform of the derivative of y is given by:

L{y'} = sY(s) - y(0) = sY(s) (assuming zero initial conditions)

L{y''} = s^2Y(s) - sy(0) - y'(0) = s^2Y(s) (assuming zero initial conditions)

Now, substituting these Laplace transforms in the given differential equation, we have:

s^2Y(s) + 4sY(s) + 2Y(s) = 4/s

Solving for Y(s), we get:

Y(s) = (4/s) / (s^2 + 4s + 2) = 2 / (s + 2)^2

Finally, taking the inverse Laplace transform of Y(s), we get:

y(t) = L^-1{Y(s)} = 2e^-2t

Therefore, the solution to the differential equation y'' + 4y' + 2y = 4 with zero initial conditions is y(t) = 2e^-2t.

Answer:

The angle marked x can be calculated using the angle sum property of a triangle. Since ∠CBE = 48° and ∠DBC + ∠BCE = 180°, then x = 180° - 48° = 132°.

Answer:Since lines AB and DE are parallel, corresponding angles are congruent. This means that angle x (which is formed by lines AB and DE) is congruent to angle CBE (which is formed by lines DE and BC). Therefore, angle x is also equal to 48 degrees.

x = 48°

Answer: D) 15.7

Step-by-step explanation:

Start with the formula C=2 πr

Then solve for r r=C2π = 98.62·π = 15.69(7)204

The radius of the circle is 15.7 mm.

The route or boundary that encircles any shape in mathematics is defined by the shape's circumference.

The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The region a circle occupies is determined by its area. The length of a straight line drawn from the centre of a circle equals the diameter of that circle.

We have,

The circumference of Circle = 2πr

Also, The circumference of a circle is 98.596 millimeters.

So, circumference of Circle = 2πr

98.596 = 2πr

98.596 = 6.28r

r= 98. 596 / 6.28

r = 15.7 mm

Thus, the radius is 15.7 mm.

If [tex]\overline{x}$[/tex] represents the mean of n observations x₁, x₂, ……xₙ, then the value of [tex]$\sum_{i=0}^{n} (x_{i} - \overline{x})$[/tex] is 0.

Mean is the average value of the group of values. It shows the equal distribution of values for a given data set.

To calculate the arithmetic mean of a group of data, first, add up (sum) all of the data values (x) and then divide the result by the number of values (n). Since ∑ is the symbol used to indicate that values are to be summed, we obtain the following formula for the mean ([tex]\overline{x}[/tex]):

[tex]\overline{x}= $\sum {\frac{x}{n} $[/tex]

The formula of the mean ([tex]\overline{x}$[/tex]) is:

[tex]\overline{x} = $\sum_{i=0}^{n} {x_{i}$/n[/tex]

[tex]$\sum_{i=0}^{n} {x_{i} = \overline{x}n[/tex]           Eqn(1)

Here, n is total number of observations.

The value of [tex]$\sum_{i=0}^{n} (x_{i} - \overline{x})$[/tex] is calculated as follows:

[tex]$\sum_{i=0}^{n} (x_{i} - \overline{x}) = \sum_{i=0}^{n} x_{i} - \sum_{i=0}^{n}\overline{x}[/tex]

Now, from equation (1), we get

[tex]$\sum_{i=0}^{n} (x_{i} - \overline{x}) = n\overline{x} - \sum_{i=0}^{n}\overline{x}[/tex]

[tex]$\sum_{i=0}^{n} (x_{i} - \overline{x}) = n\overline{x} - \overline{x}\sum_{i=0}^{n}1[/tex]

[tex]$\sum_{i=0}^{n} (x_{i} - \overline{x}) = n\overline{x} - \overline{x}n[/tex]

[tex]$\sum_{i=0}^{n} (x_{i} - \overline{x}) = 0[/tex]

Sample 3's mercaptoethanol and urea mixture breaks sulphide bonds, resulting in the loss of tertiary structure and activity, whereas in sample 2, urea is introduced. This chemical denaturing agent aims to break up peptide connections, which would then affect the structure and function of the protein.

An experiment data is given below:

This experiment describes how protein denaturing chemicals affect a protein's ability to function.

Sample 1 preserves protein structure and function because it just contains buffer and no denaturing agent.

Enzymatic activity then results in high fluorescence as a result of this.

In sample 2, urea is added, a chemical denaturing agent that seeks to dismantle peptide bonds, disrupting protein structure and activity.

As a result, there are now less fluorescence products and less active enzyme products overall.

In sample 3, when mercaptoethanol and urea are mixed, sulphide bonds are broken and tertiary structure and activity are lost.

After dialysis, sample 4 had both urea and mercaptoethanol eliminated from it.

Three edges and three vertices make up the three-sided polygon known as a triangle. The fact that a triangle's internal angles can be added up to equal 180 degrees is its most significant characteristic.

Three straight lines coming together create a triangle. There are three sides and three corners on every triangle (angles). A triangle's vertex is the intersection of two of its sides. Any one of a triangle's three sides can serve as its base, however typically the bottom side is used.

Each side is different, and each angle is less than 90 degrees. Obtuse isosceles: two identical sides and identical angles, with one angle more than 90 degrees.

The properties of multiplication are distributive, commutative, associative, removing a common factor and the neutral element.

Step-by-step explanation:

The distributive, commutative, associative, removes a common factor, and neutral element characteristics of multiplication.

According to the associative property, grouping symbols can be altered during addition or multiplication without affecting the outcome.

A + (b + c) = A + (b + c) is how this is expressed. In order to multiply a number by all of the distinct addends of another number, one must use the distributive property of multiplication.

A mathematical principle known as the associative property states that the product of a multiplication problem is unaffected by the way the factors are organized.

You can arrange the addends in multiple ways without changing the result, according to the associative property of addition. You can reorder the addends and the result won't change, according to the commutative property of addition.

By using the Angle Sum Property, we can find that m angle a = 180 - (3(x - 5) + x 25) = 180 - 4x + 25

We can use the Angle Sum Property to solve this problem. The Angle Sum Property states that the sum of the measures of the angles in a triangle is equal to 180°. We can use this to write the equation 180 = m angle bdc + m arc bc + m angle a. Since we have the values for m angle bdc and m arc bc, we can plug them in and rearrange the equation so that m angle a is the only unknown. We get 180 = 3(x - 5) + x 25 + m angle a. Subtracting 3(x - 5) + x 25 from both sides, we get m angle a = 180 - (3(x - 5) + x 25). Simplifying, we get m angle a = 180 - 4x + 25, which is the final answer.
