The volume of the solid is equal to the integral of the area of the semi-circular cross sections multiplied by the length of the interval. The area of the semi-circular cross sections is equal to πr²/2, where r is the diameter running from y. Therefore, the volume is equal to π/2∫0,9r²dy.
Step 1: Substitute the expression for the area of the semi-circular cross section into the equation for the volume of the solid:
V = π/2∫0,9r²dy
Step 2: Integrate the equation to find the volume of the solid:
V = π/2[y³/3]|0,9
Step 3: Evaluate the integral:
V = π/2(9³/3 - 0³/3)
step 4: Solve for the volume of the solid:
V = 7π/2
The volume of the solid is equal to the integral of the area of the semi-circular cross sections multiplied by the length of the interval. The area of the semi-circular cross sections is equal to πr²/2, where r is the diameter running from y. Therefore, the volume is equal to π/2∫0,9r²dy. To calculate the volume, we must first substitute the expression for the area of the semi-circular cross sections into the equation for the volume of the solid: V = π/2∫0,9r²dy. Then, we must integrate the equation to find the volume of the solid: V = π/2[y³/3]|0,9. After that, we must evaluate the integral: V = π/2(9³/3 - 0³/3). Finally, we must solve for the volume of the solid: V = 7π/2. The answer is the volume of the solid is 7π/2.

Suppose y varies directly with x. Write a direct variation equation that relates x and y. y=5 and x=2
A direct variation equation that relates x and y is y = (5/2)x.
What is the direct variation equation?
Direct variation is a linear function defined by an equation of the form y = kx when x is not equal to zero. Inverse variation is a nonlinear function defined by an equation of the form xy = k when x is not equal to zero and k is a nonzero real number constant.
When two variables are directly proportional, they vary directly with each other.
The relationship between the variables can be represented by a direct variation equation of the form:
y = kx
where k is the constant of proportionality.
Given that y = 5 and x = 2, we can use these values to find the value of k:
y = kx
5 = k(2)
k = 5/2
So the direct variation equation that relates x and y is:
y = (5/2)x
This equation shows that for every value of x, the value of y is 5/2 times that value.
For example, if x = 3, then y = (5/2) * 3 = 7.5, and if x = 4, then y = (5/2) * 4 = 10.
Hence, A direct variation equation that relates x and y is y = (5/2)x.

Suppose that A is countable set. Show that the set B is also countable if there is an onto function f from A to B
Let A and B be two countable sets. Then there exists a bijective function f from A to B.
Since f is onto, for every element b in B, there exists a unique element a in A such that f(a)=b. This implies that the number of elements in B is equal to the number of elements in A, i.e. B is also countable.
Formally, if A = {a1, a2, ..., an}, then B = {f(a1), f(a2), ..., f(an)}. Since f is onto, B has n elements, which implies that B is countable.
Let A be a countable set and let B be a set with an onto function f from A to B. Since A is countable, it can be written as an infinite sequence of distinct elements an, where n is a natural number. To show that B is also countable, we can construct a one-to-one correspondence between the elements of A and B. We can do this by assigning bi to the element ai in A, for each i. Thus, we can write B as an infinite sequence of distinct elements bn, where n is a natural number. Therefore, B is countable.

9^10 divided by 9 can be simplified to 9^(10-1) = 9^9
This is because when dividing a power by the same base, we can subtract the exponent by one.
In other words, 9^10 / 9 = (9999999999) / (9) = 99999999*9 = 9^9.
So, 9^10 divided by 9 is equal to 9^9.
Another way to think about this is that dividing a number by itself is the same as multiplying that number by 1, and 9^10 / 9 = 9^10 * 1 / 9 = 9^10 / 9^1 = 9^(10-1) = 9^9
In terms of real numbers, 9^10 is equal to 387420490 and 9^9 is equal to 3486784401. So 9^10 divided by 9 is equal to 3486784401.

Siegell's Locksmith Shop is taking out a mortgage on a new building. It is going to be an interest-only, 12-year balloon mortgage for $350,000. The APR is 3.35%. The last payment will be the balloon payment of the full principal.
a. Find the total number of monthly payments, not including the final balloon payment.
b. Find the amount of each monthly payment if the payments are interest-only. Round to the nearest cent.
c. Find the difference between the regular monthly payment and the balloon payment, to the nearest hundred dollars.
d. If the mortgage was not a balloon mortgage, what would be the amount of the monthly payment, rounded to the nearest cent?
Total number of monthly payments, not including the final balloon payment is $1,195.77
How to solve the problem?The monthly payment is the sum that must be paid each month for the duration of the loan to cover the principal balance. When a loan is taken out, not only the principal—the amount that was initially loaned out—but also the interest—which accrues—must be repaid.
Step1
M = 350,000(0.071/12)(1+0.071/12)² /(1+0.071/12)¹² =3,618.02
M = P(r/12) (1+r/12)¹²×n/(1+r/12)¹²×n -1
Step2:
3,618.02 × 12 × 12 = 520,994.88
The total paid is the product of the monthly payment and the number of payments.
520,994.88 - 350,000 = 170,994.88
= 170,994.88÷143

a convex pentagon has exterior angles with measures 75°, 62°, 68°, and 101°. the measures of the last exterior angle is?
A convex pentagon has five exterior angles, and the sum of the measures of these angles is equal to 360 degrees.
We know that the measures of the exterior angles of a convex pentagon are 75°, 62°, 68°, and 101°, we need to find the measure of the last exterior angle.
To find the measure of the last exterior angle, we can use the formula:
Sum of all exterior angles = (n-2) x 180
where n is the number of sides in the polygon.
For a pentagon, n = 5, so the sum of all exterior angles is (5-2) x 180 = 540 degrees
So we can use this information to find the measure of the last exterior angle:
75 + 62 + 68 + 101 + x = 540
x = 244
Therefore, the measure of the last exterior angle is 244 degrees.

What is linear equations?A system of linear equations is a set of equations with two or more variables. A linear equation is one that can be expressed as ax + b = c, where x is a variable and a, b, and c are constants.
A group of two or more linear equations that share the same variables is known as a system of linear equations. As an illustration, consider the set of linear equations below:
2x + 3y = 10
4x + 6y = 20
x and y are the same variables, and the equations are linear equations. The solution to this system of linear equations is x = 2, y = 2.
This question can be solved using the system of linear equations.
Solving the system of equations gives:
T = 7.4 cups of tomatoes in each jar
Step 1: Calculate the total amount of tomatoes used.
Total tomatoes = 8 jars x cups of tomatoes per jar
Total tomatoes = 8 x (41.6 - 2.1)
Total tomatoes = 303.2 cups
Step 2: Divide the total amount of tomatoes by the total number of jars.
Cups of tomatoes per jar = Total tomatoes ÷ 8
Cups of tomatoes per jar = 303.2 ÷ 8
Cups of tomatoes per jar = 37.9 cups

Find the surface area of the cylinder. Round your answer to the nearest tenth if necessary.A cylinder with diameter of 6 centimeters and height of 12 centimeters.
Answer:282.6 cm²
Step-by-step explanation:
The formula for the surface area of a cylinder is 2πr(r+h) where r is the radius and h is the height.
Since the diameter is given, we can find the radius by dividing the diameter by 2, so r = 6/2 = 3 cm.
Then we can plug in the values into the formula:
2πr(r+h) = 2π(3)(3+12) = 2π(3)(15) = 90π cm²
To round the answer to the nearest tenth, we can use the following method:
If the digit in the thousandths place is less than 5, we keep the hundredths digit as is.
If the digit in the thousandths place is greater than 5, we round up the hundredths digit.
Since π is an irrational number it can't be rounded to the nearest tenth. But an approximation for π is 3.14 and 90π is approximately 282.6 cm².

Answer:
A. No, because (-1) and (-1, -2) have the same input value.
Step-by-step explanation:
Functions:So what exactly is a function? It's very similar to a relation where there is input and for each input we have some output and sometimes multiple. The difference is in a function there is only one output for each input. Now the outputs of two different inputs can be the same, such that the input 2 and 3 will both output 4 or any value, but we cannot have an input such as 2 outputting 3 and 4 since we can only have one output for each input.
In the table given, the input "-1" outputs "2" and -2" which means the table does not represent a function.

Let the coordinates of B=(x,y).
Since ABCD is a square,
[tex]AB=BC=AB^2=BC^2.[/tex]
Using distance formula,
[tex](x-3)^2+(y-2)^2=(x-0)^2+(y+5)^2[/tex]
⟹2x+8y−6=0
⟹x=([tex]\frac{6-8y}{2}[/tex] ) .........(i).
Now, in ΔABC,
[tex]AB ^2+BC ^2=AC ^2[/tex]
[tex](x-3)^2+(y-2)^ 2+(x-0) ^2 +(y+5)^ 2=(3-2) ^2+(0+5) ^2[/tex]
⟹[tex]x^ 2+y ^2 -3x-3y=0.[/tex]
Substituting for x from (i),
[tex](\frac{6-8y}{2} )^2+y ^2 -3(\frac{6-8y}{2} )-3y=0[/tex]
⟹[tex]3y^2-9y+4=0[/tex]
⟹[tex](2y-1)(2y-4)=0[/tex]
⟹[tex]y=( \frac{1}{2},\frac{4}{2} ).[/tex]
Substituting for y in (i),
[tex](x,y)=( \frac{9}{2},\frac{1}{2} ) & (-\frac{1}{2} , \frac{4}{2} )[/tex]Now abscissae of A & C are 3 & 1, respectively.
∴ Abscissa of B will be in between 1 & 3.
So here, [tex]\frac{9}{2}[/tex] will be the abscissa of B.
Coordinates of B & D are [tex](\frac{9}{2} ,\frac{1}{2} ) & (-\frac{1}{2} ,\frac{4}{2} )[/tex] respectively.

The coordinates of the remaining vertices B and D are (0, 2) and (-3, 5) respectively.
What are the coordinates of the vertices?
The unit square precisely refers to the square on the Cartesian plane having four corners.
Since square ABCD has a diagonal with the given vertices A(-3, 2) and C(0, 5), we know that the other two vertices of the square will be B and D, and that all four sides of the square are congruent.
We can use the coordinates of A and C to find the coordinates of B and D.
First, we know that the x-coordinate of B must be the same as the x-coordinate of C because the side BD is parallel to the x-axis.
Therefore, the x-coordinate of B is 0.
Next, we know that the y-coordinate of B must be the same as the y-coordinate of A because the side AB is parallel to the y-axis.
Therefore, the y-coordinate of B is 2.
So, the coordinates of B are (0, 2).
Finally, we know that the x-coordinate of D must be the same as the x-coordinate of A because the side AD is parallel to the x-axis.
Therefore, the x-coordinate of D is -3.
Next, we know that the y-coordinate of D must be the same as the y-coordinate of C because the side CD is parallel to the y-axis.
Therefore, the y-coordinate of D is 5.
So, the coordinates of D are (-3, 5)
Therefore, the coordinates of the remaining vertices B and D are (0, 2) and (-3, 5) respectively.

A landscaper needs to mix a 70% pesticide solution with 20 gal of a 15% pesticide solution to obtain a 65% pesticide solution. How many gallons of the 70% solution must he use?
(blank) gal of the 70% pesticide solution is needed to make a final solution that is 65% pesticide.
Step-by-step explanation:
70% = 0.7
15% = 0.15
65% = 0.65
x = gallons of the 70% solution.
0.7x + 0.15×20 = 0.65(x + 20)
70% + 15% solution = 65% solution (which has a many gallons as the combination of x and 20 gallons).
0.7x + 3 = 0.65x + 0.65×20
0.05x + 3 = 13
0.05x = 10
x = 10/0.05 = 200 gallons
so, 200 gal of the 70% pesticide solution is needed to make combined with 20 gal of the 15% solution a final solution that is 65% pesticide.
HELP!!! You go out to dinner and the bill comes to $40.94. How much should you tip if you want the tip to be 15.0% of the bill? Express the dollar amount to the nearest cent
On average, 15-20% of the cost is left as a gratuity. Add the desired decimal percentage tip to the total amount of the check and multiply the result to determine the tip.
How much should you leave for tip?
15% to 20% of the tab is typically left as a gratuity. Add the decimal % tip you want to leave to the total check amount to compute the tip. You would multiply 1 by 0.20 to reach 1.20 if you wanted to leave a 20% tip. To calculate the total amount you would tip, multiply the bill by 1.20.
It is advised that you leave at least 10% of your tip, even if the service was subpar. * Because some restaurants tack on a gratuity, carefully review your tab. Whether or not you should add to that is up to you. In sit-down restaurants, the tip for the wait staff should be between 15 and 20 percent of the pretax total.
To find out the tip amount, we need to first calculate 15% of the bill:
$40.94 x 0.15 = $6.14.
Rounding this amount to the nearest cent, we get $6.14 as the tip amount.
Therefore, the tip total is$ 7.00
