Rewrite the statement in mathematical notation. (Let n be the number of cases of Bangkok flu and t be time.) There are presently 450 cases of Bangkok flu, and the number is growing by 10 new cases every month.
dn/dt=
Answers
Final answer:
To represent the growth of Bangkok flu cases over time mathematically, the derivative dn/dt equals 10, indicating a constant increase of 10 cases per month.
Explanation:
To rewrite the statement in mathematical notation where n is the number of cases of Bangkok flu and t is time, we will express the changing number of cases as a function of time. Given that there are currently 450 cases and the number of cases is growing by 10 every month, we would write the instantaneous rate of change of the number of cases with respect to time as dn/dt = 10.
This is because the phrase 'growing by 10 new cases every month' implies a constant rate of growth over time, which is directly translated into a derivative in mathematical terms. In more complex scenarios, rates of growth could follow a pattern that might be represented by a function of t. However, in this case, the growth is linear and constant, which simplifies to the derivative being equal to the rate of growth: 10 cases per month.

write the quotient in standard form:
8-7i/1-2i
Answers
22/5+(9/5)i
To get rid of i in the denominator, use the difference-of-two-squares formula: (a+b)(a-b) = a²-b²
The denominator of your fraction is 1-2i. If we were to multiply the denominator by (1+2i), we would get (1-2i)(1+2i) = 1-(-4) = 5.
Of course, if we are going to multiply the denominator by (1+2i), we must also multiply the numerator by (1+2i). So your numerator becomes:
(8-7i) * (1+2i) = 8 + 16i - 7i +14 = 22+9i
Thus,
(8-7i) / (1-2i) = (22+9i) / 5
But standard form requires that we complete the division. So:
(8-7i) / (1-2i) = 22/5 + (9/5)i
The answer, then, is 22/5 + (9/5)i
The quotient in standard form for (8 - 7i) / (1 - 2i) is (22 + 9i) / 5. In this form, the numerator has real and imaginary components, while the denominator is a real number.
The division is simplified, providing a representation of the complex number in a standard format.
To write the quotient result of division in standard form,
Get rid of the imaginary unit 'i' from the denominator.
To do that, multiply both the numerator and the denominator by the conjugate of the denominator. The conjugate of 1 - 2i is 1 + 2i.
So, let's perform the multiplication:
(8 - 7i) / (1 - 2i) × (1 + 2i) / (1 + 2i)
Now, use FOIL (First, Outer, Inner, Last) method to expand the numerator:
Numerator = (8 - 7i)(1 + 2i)
= 8 + 16i - 7i - 14i² (remember that i² is -1)
= 8 + 9i - 14(-1)
= 8 + 9i + 14
= 22 + 9i
Now, let's expand the denominator:
Denominator = (1 - 2i)(1 + 2i)
= 1 + 2i - 2i - 4i²
= 1 - 4i²
= 1 - 4(-1)
= 1 + 4
= 5
Therefore, the quotient in standard form is (8 - 7i) / (1 - 2i) = (22 + 9i) / 5.

Final answer:
To find John's original savings, we set up an equation based on the information given and solved for the total savings, which was found to be approximately $154.29.
Explanation:
John spent $24 on a watch and then 1/5 of the remainder of his savings on a shirt. After these purchases, he had 2/3 of his savings left. To determine John's original savings, let's represent his total savings as S. After purchasing the watch, John had S - $24 remaining. He then spent 1/5 of this remainder on a shirt. After buying the shirt, 2/3 of his savings was left, which can be represented by the equation:
2/3 * S = (S - $24) - 1/5 * (S - $24)
Now, we can solve for S, by first distributing the 1/5 on the right-hand side of the equation:
2/3 * S = (S - $24) - 1/5 * S + 24/5
Then, we combine like terms:
(2/3 - 1/5) * S = $24 - 24/5
To combine the fractions, find a common denominator, which in this case is 15:
(10/15 - 3/15) * S = 96/5 - 24/5
(7/15) * S = 72/5
Finally, we multiply both sides of the equation by the reciprocal of 7/15 to solve for S:
S = (72/5) * (15/7)
S = (72*15)/(5*7)
S = $154.29
Therefore, John's original savings was approximately $154.29.

Final answer:
The surface area of a cone with height h and base radius a, excluding the base, is found using the lateral surface area formula A = π · a · l, where l is the slant height given by √(a² + h²).
Explanation:
To find the general formula for the surface area of a cone with height h and base radius a using a surface integral, excluding the base, we consider the lateral surface area of the cone. This is given by the integral along the slant height of the cone. To derive the formula, the slant height, l, can be found using the Pythagorean theorem, since the triangle formed by the slant height, radius of the base, and the height of the cone is a right triangle. The relationship is given by l = √(a² + h²).
The lateral surface area A can then be expressed as A = π · a · l. Substituting for the slant height, we get A = π · a · √(a² + h²), which is the desired formula.
This formula assumes that the cone is a right circular cone and the lateral surface is a smooth curve.

Tammy is at the dentist's office waiting on her appointment. She notices that the 6-inch-long minute hand is rotating around the clock and marking off time like degrees on a unit circle. Part 1: How many radians does the minute hand move from 1:20 to 1:55? (Hint: Find the number of degrees per minute first.)
Answers
From 1:20 to 1: 55 we have 35 minutes or 7 x 5 minutes or
7 x 30° = 210°
To convert degree into radian, we apply the following formula:
degree/180° = radian/π
210/180 = r/π or (cross multiplication) →Radian = (π x 210/180
→ Radian = 7π/6 (simplify by 30)
Answer:
Part 1:
In order to find how many radians the minute hand moves from 1:20 to 1:55, we need to remember that there are 60 minutes in an hour (clock) and there are 360 degrees in the clock since the clock is a circle. After dividing 360 by 60, we find that each minute is equal to 6 degrees. After that, we can subtract the times, which tells us that there are 35 minutes between 1:20 and 1:55. Using this we can just multiply this out, to get 35 times 6, which is equal to 210 degrees. We can get our final answer by converting this into degrees. Since one 1 degree is about 0.0174, we can set up a proportion. After solving, we will get that the minutes hand moves 3.555 radians in total.

What is the center of a circle whose equation is x^2+y^2-12x-2y+12=0
Answers
(x-H)² + (y-K)² = r² where (H, K) are the coordinates for the center of the circle and r is the radius. You can do this by completing the square for both x and y terms:
x² + y² - 12x - 2y + 12 = 0
x² + y² - 12x - 2y = -12
x² - 12x + y² - 2y = -12
To complete the square take half of the x-term and square it then add it to both sides of the equation. So take half of -12 which is -6, square it: -6² = 36 and add it to both sides.
x² - 12x + 36 + y² - 2y = -12 + 36
Do the same for y:
x² - 12x + 36 + y² -2y + 1 = -12 + 36 + 1
Now reduce each perfect square polynomial to squared form by remembering the FOIL rule for factoring:
(Ax + B)(Cx + D)
First + Outer + Inner + last
A²x² + ADx + BCx + D²
Now just work backwards and figure out what terms multiply to give you the trinomial you have. Let's start with the x :
x² - 12x + 36
Looks like 36 is perfect square of 6 and the negative sign in the middle term indicates subtract 6, so x - 6. Check it!
(x - 6)² = x² - 3x - 3x + 36 = x² - 6x + 36
Yes, it works! Now the y :
y² - 2y + 1
This looks good too since 1 is a perfect square:
(y - 1)² = y² - 1y - 1y + 1 = y² - 2y + 1
Perfect!
Now put it back into the equation:
x² - 12x + 36 + y² - 2y + 1 = -12 + 36 + 1
(x - 6)² + (y - 1)² = -12 + 36 + 1
Simplify the right:
(x - 6)² + (y - 1)² = 25
Beautiful! The equation of the circle! The center is (6,1) with radius 5. Now we can attack the parts in the question.
(a) First part asks us to find point B, knowing point A is (3,-3) and that AB is a diameter of the circle. Since we know the coordinates of the center and the fact that a diameter is just a line that goes through the center, we have 3 points on the line: A, B, and the center. We can just realize that the point B is equidistant and exactly opposite the point A with respect to the center. So let's find the difference between point A and the center, and move that distance to get to B:
center - A = (1 - -3) / (6 - 3) = (1 + 3) / (6 - 3) = 4 / 3
How are the rules for division of signed numbers similar to the rules for multiplication of signed numbers?
Answers
like the sign of the product or quotient will be positive. Multiply or divide, if the signs aredifferent unlike the sign of the product or quotient will be negative
Final answer:
The division and multiplication of signed numbers follow the same sign rules: two positive numbers yield a positive result, two negatives give a positive, and a pair of numbers with different signs results in a negative outcome.
Explanation:
The rules for the division of signed numbers are similar to the rules for multiplication of signed numbers. Both operations follow the same pattern concerning the signs of the numbers involved:
When two positive numbers are involved, the result is positive (e.g., [tex]\frac{2}{1} = 2[/tex] or 2 x 1 = 2).
When two negative numbers are involved, the result is also positive (e.g., [tex]\frac{-2}{-1} = 2[/tex] or (-4) x (-3) = 12).
When one positive and one negative number are involved, irrespective of the operation, the result is negative (e.g., [tex]\frac{-3}{1} = -3[/tex] or (-3) x 2 = -6).
Therefore, both division and multiplication of signed numbers primarily depend on the signs of the numbers to determine the sign of the answer.

Three times a first number decreased by a second number is 1. the first number increased by twice the second number is 12. find the numbers.
Answers
Final answer:
The first number is 2 and the second number is 5.
Explanation:
Let's represent the first number as x and the second number as y.
According to the problem, we have the following equations:
3x - y = 1 (Equation 1)
x + 2y = 12 (Equation 2)
To solve this system of equations, we can use the method of substitution. We can rearrange Equation 2 to solve for x:
x = 12 - 2y
Now, we substitute this value of x into Equation 1:
3(12 - 2y) - y = 1
Expand and solve for y:
36 - 6y - y = 1
Combine like terms:
-7y = -35
Divide both sides by -7:
y = 5
Now, substitute this value of y back into Equation 2 to find x:
x + 2(5) = 12
x + 10 = 12
Subtract 10 from both sides:
x = 2
Therefore, the first number is 2 and the second number is 5.
