what is cylinder ?A cylinder is really a muti geometric shape made up of two circular bases that are congruent and parallel to one another, as well as a curving lateral surface that links the bases. It can be envisioned as a reasonable shape that is created by extending a circle perpendicular to the plane of the circle. Several advantageous characteristics of the cylinder, such as a constant bridge area over its whole length, make it suitable for a wide range of practical applications. For instance, a lot of different kinds of containers, such pipes and tubes, have cylindrical shapes. The following formula can be used to figure out the size of a cylinder:[tex]V = \pi r^2h[/tex] where V is the capacity, r is the circumference of the spherical base, and h is the cylinder's height.
given
We must apply the formula for a cylinder's surface area, which is: to determine the cylinder's height.
[tex]SA = 2\pi r^2 + 2\pi rh[/tex]
where SA stands for surface area, r for base radius, and h for cylinder height.
The cylinder has a radius of 2.5 m and a diameter of 5 m.
[tex]13 = 2\pi (2.5)^2 + 2\pi (2.5)h[/tex]
13 = 39.27 + 15.71h

The x⁶y³ term in the expansion will be: 35 x⁶y³.
The x⁸y² term in the expansion will be: 21x⁸y².
What is the binomial expansion?The binomial expansion of (x + y)ⁿ is given by the binomial theorem, which states:
(x + y)ⁿ = C(n, 0) * xⁿ * y⁰ + C(n, 1) * xⁿ⁻¹ * y¹ + C(n, 2) * xⁿ⁻² * y² + ... + C(n, k) * xⁿ⁻ᵏ * yᵏ + ... + C(n, n) * x⁰ * yⁿ
where;
C(n, k) is the binomial coefficient, defined as C(n, k) = n! / (k! * (n - k)!), and n! represents the factorial of n.Given that the term 210x⁴y⁶ appears in the expansion, we can infer that it corresponds to C(n, k) * x⁴ * y⁶, where k is the number of times y appears in the term, and (n - k) is the number of times x appears in the term.
Comparing this with the given term, we can deduce the values of n, k, and x in the following way:
C(n, k) = 210
x⁴ = x⁴
y⁶ = y³ * y³
Comparing the exponents on x and y, we can set up the following equations:
n - k = 4 (1)
k = 3 (2)
Solving equation (2) for k, we get:
k = 3
Substituting this value of k into equation (1), we can solve for n:
n - 3 = 4
n = 7
So, the value of n is 7.
Now, we can use the binomial coefficient formula to calculate C(n, k):
C(n, k) = C(7, 3) = 7! / (3! * (7 - 3)!) = 35
Finally, substituting the values of n, k, and C(n, k) into the general term of the expansion, we can find the specific terms:
The x⁶y³ term in the expansion will be:
C(7, 3) * x⁶ * y³ = 35 * x⁶ * y³
The x⁸y² term in the expansion will be:
C(7, 2) * x⁸ * y² = 21 * x⁸ * y²

Step-by-step explanation:
given FH is a diameter , then
arc FH = 180°, that is
FG + GH = 180°
103° + GH = 180° ( subtract 103° from both sides )
GH = 77°
the central angle HIG is equal to the arc that subtends it GH , so
∠ HIG = 77°
∠ EIF and ∠ HIG are vertically opposite angles and are congruent , then
∠ EIF = 77°
the arc EF subtends the central angle EIF , so
EF = 77°
the sum of the 3 arcs = 180° , that is
HD + DE + EF = 180
15 + 18x - 2 + 77 = 180
18x + 90 = 180 ( subtract 90 from both sides )
18x = 90 ( divide both sides by 18 )
x = 5
then arc DE = 18x - 2 = 18(5) - 2 = 90 - 2 = 88°

The length of a rectangle is 2 units more than the width. The area of the rectangle is
24 square units. What is the width, in units, of the rectangle?
The width of the rectangle is 4 units.
What is rectangle?
Rectangle is a four sided polygon or specifically a particular type of parallelogram having two opposite sides are equal and one angle is right angle that is 90°. It has four vertices and two diagonals intersect each other.
Given that,
The length of a rectangle is 2 units more than the width.
Let, the width of the rectangle is w units.
Then the length of the rectangle is w+2 units.
Area of any rectangle is length × width
= (w+2)×w square units
Given that,
The area of the rectangle is 24 square units.
Equating both the values we get,
w(w+2)= 24
We have to solve the equation for w.
Multiplying the bracket term with w we get,
w²+ 2w = 24
⇒ w² + 2w- 24=0
⇒ (w+6)(w-4)=0
so either w= -6 or w=4
As width cannot be negative so w= 4.
Hence, the width of the rectangle is 4 units.

To solve the system of equations using subtraction, you need to eliminate one of the variables by adding or subtracting the equations. In this case, we can eliminate x by multiplying the first equation by 2 and subtracting it from the second equation:
2x - 5y = 1
- (2(x - 6y) = 2x - 12y = 22)
------------------------
-17y = -21
Now we can solve for y:
-17y = -21
y = (-21) / (-17)
y = 1.2353
Substitute y into one of the original equations to solve for x:
x - 6y = 11

What is null hypothesis?A null hypothesis is a statement that establishes the equality of two expressions and frequently includes variables, constants, and mathematical operations.
The equal sign (=) is used to denote the space between the two sides, which are referred to as the left-hand side (LHS) and the right-hand side (RHS).
To test the given hypothesis, we will use the F-test for two variances.
The null and alternative hypotheses are:
H0: σ1² = σ2² (no difference in population variances)
Ha: σ1² > σ2² (population variance of first group is greater than that of second group)
The test statistic is calculated as:
F = s1² / s2²
Where s1² and s2² are the sample variances of the two groups.
The degrees of freedom for the F-distribution are df1 = n1 - 1 and df2 = n2 - 1.
Using the given sample information, we have:
n1 = 10, n2 = 11
s1² = 562, s2² = 1013
Therefore, the test statistic is:
F = s1² / s2² = 562 / 1013 = 0.555
The degrees of freedom are df1 = 9 and df2 = 10.
Using a significance level of α = 0.01 and the F-distribution tables or a calculator, the critical value for the right-tailed test with df1 = 9 and df2 = 10 is 4.025.
Since the calculated F-value of 0.555 is less than the critical value of 4.025, we fail to reject the null hypothesis. There is not enough evidence to conclude that the population variance of the first group is greater than that of the second group at a significance level of α = 0.01.

What is radioactive decay?An unstable atomic nucleus releases particles or electromagnetic radiation as it undergoes radioactive decay, changing into a different nucleus. Since this process is unpredictable and spontaneous, the decay's timing cannot be anticipated. The radioactive substance's half-life, or the amount of time it takes for half of its radioactive atoms to decay, is used to calculate the rate of decay. Radiometric dating, nuclear energy production, and medical imaging all employ radioactive decay, which can cause the emission of alpha particles, beta particles, or gamma rays. Understanding the behaviour of matter at the atomic and subatomic level requires knowledge of radioactive decay.

What is graph?A graph is a visual representation of data that shows the relationship between two or more variables. Graphs are commonly used to display information in a way that is easy to interpret and analyze. They are often used in fields such as science, mathematics, economics, and engineering to help illustrate and explain complex data.
Here,
The introduction of a cost of 0.25 cents per mile for the driver would be an additional expense for the trucking company, and would affect their profit. This means that the profit values (on the y-axis) would decrease for each point on the graph. However, the miles traveled (on the x-axis) would remain the same as the cost of the driver is proportional to the distance traveled.
Therefore, the y-intercept of the graph (the profit when the truck has traveled zero miles) would be less than it was before, because the trucking company has a new cost that reduces their overall profit. However, the x-intercept (the point where the profit is zero) would remain the same, as this point is determined solely by the revenue and cost of the trucking company.
The slope of the graph would also be affected, as the profit now decreases at a faster rate as the miles traveled increase. The new slope would depend on the specific values of the revenue, costs, and driver expenses for the trucking company, but in general, it would be steeper than before.

Suppose a supermarket ordered 13 cases of organic vegetable soup with a list price of $18.90 per case and 4 cases of organic baked beans with a list price of $33.50 per case. The wholesaler offered the supermarket a 39% trade discount. (Round your answers to the nearest cent.)
What is the total net amount (in $) the supermarket owes the wholesaler for the order?
$
So, the total net amount the supermarket owes the wholesaler for the order is $231.61.
To find the total net amount that the supermarket owes the wholesaler for the order, we need to first calculate the cost of each item after the trade discount is applied, and then add up the costs of all the items.
For the 13 cases of organic vegetable soup, the list price per case is $18.90, and the trade discount is 39%. So, the discount amount per case is:
Discount amount = 39% x $18.90 = $7.37
The cost per case after the discount is:
Cost per case = $18.90 - $7.37 = $11.53
So, the total cost of 13 cases of organic vegetable soup is:
Total cost of vegetable soup = 13 x $11.53 = $149.89
Similarly, for the 4 cases of organic baked beans, the list price per case is $33.50, and the trade discount is 39%. So, the discount amount per case is:
Discount amount = 39% x $33.50 = $13.07
The cost per case after the discount is:
Cost per case = $33.50 - $13.07 = $20.43
So the total cost of 4 cases of organic baked beans is:
Total cost of baked beans = 4 x $20.43 = $81.72
Therefore, the total net amount the supermarket owes the wholesaler for the order is:
Total net amount = Total cost of vegetable soup + Total cost of baked beans
= $149.89 + $81.72
= $231.61
So, the total net amount the supermarket owes the wholesaler for the order is $231.61.
