What is the length of the radius of a circle with a center at the origin and a point on the circle at 8 + 15i?
Answer:
Hence, the length of the radius of a circle with center at origin is 17 units.
Step-by-step explanation:
" We know that radius of a circle is any line segment joining center to any point on the circle ".
We have to find the length of the radius of a circle with a center at the origin i.e. (0,0) and a point on the circle at 8 + 15i i.e. at (8,15).
( Since any complex number of the form z=x+iy has a point in the coordinate plane as: (x,y) ).
Hence , we have to find the distance between the point (0,0) and (8,15).
The distance between two points (a,b) and (c,d) is given by:
[tex]\sqrt{(a-c)^2+(b-d)^2}[/tex]
Here (a,b)=(0,0) and (c,d)=(8,15)
Hence distance between (0,0) and (8,15) is:
[tex]\sqrt{(0-8)^2+(0-15)^2\\} \\=\sqrt{(8)^2+(15)^2\\} \\=\sqrt{64+225}\\ \\=\sqrt{289}\\ \\=17[/tex]
Hence, the length of the radius of a circle with center at origin is 17 units.
Answer: 17
Step-by-step explanation: the length of the radius of a circle with center at origin is 17 units.

If the original 24 m edge length x of a cube decreases at the rate 5m/min, when x=3 at what rate does the cube's surface area change
The change in the cube's surface area is -180 m^2/min when the edge length is 3 m. This is found by differentiating the surface area with respect to time and substituting the given values.
Explanation:The subject of the question is related to rates of change in the context of the geometry of a cube. To address this problem, we use the formula for a cube's surface area, which is given by A = 6x^2, where x represents the length of an edge. If x changes with respect to time, we denote this change as dx/dt, which is given as -5m/min. You want to find how quickly the surface area, A, changes when x = 3.
First, let us differentiate the surface area A with respect to time t. By the chain rule of differentiation, dA/dt = dA/dx * dx/dt. Given A = 6x^2, dA/dx = 12x. substituting x=3 and dx/dt=-5, we find that dA/dt = 12*3*-5, which equals -180m^2/min.
Therefore, the change in the cube's surface area is -180 m^2/min when the edge length is 3 m.

A whale has a tracking device attached to it. The whale traveled 184 miles in 6 hours. About how fast did the whale swim per hour?
Final answer:
To find the whale's average speed per hour, divide the total distance of 184 miles by the time of 6 hours, resulting in an average speed of approximately 30.67 miles per hour.
Explanation:
The question asks for the speed of a whale per hour based on a certain distance traveled over a period of time. To calculate the speed of the whale, we can use the formula:
Speed = Distance ÷ Time
In this case, the whale traveled 184 miles in 6 hours. Using the formula, we divide 184 miles by 6 hours:
Speed = 184 miles ÷ 6 hours = 30.67 miles per hour
So, the whale swam at an average speed of about 30.67 miles per hour.
A chef uses 3 3/4 pounds of semolina flour and 1 5/8 pounds whole wheat flour for each batch of pasta she makes. One week she uses a total of 86 pounds of flour.
Write an equation to solve for b, the number of batches of pasta the chef makes during the week.
How many batches of pasta does she make? Show your work.
To find the number of batches of pasta, convert the amount of flour per batch to an improper fraction, create an equation based on the total flour used, and solve for the number of batches, which is 16.
To solve for b, the number of batches of pasta the chef makes during the week using a total of 86 pounds of flour:
First, convert the amounts of each flour from mixed numbers to improper fractions:
1 5/8 pounds = 13/8 pounds
Now add the two amounts together to get the total flour used per batch:
(15/4) + (13/8) = 30/8 + 13/8 = 43/8 pounds per batch
The equation to solve for b is:
(43/8) * b = 86
To find b:
b = 86 / (43/8)
Multiply both sides by the reciprocal of 43/8:
b = 86 * (8/43)
b = (86 * 8) / 43
Calculate the value of b:
b = 688 / 43
b = 16

SSS similarity theorem states: If the corresponding sides of two triangles are proportional, then the two triangles are similar.
You have two isosceles triangle, then if
[tex]\dfrac{44}{20}=\dfrac{x}{35},\\ \\x=\dfrac{44\cdot 35}{20}=11\cdot 7=77,[/tex]
two isosceles triangles will be similar by SSS theorem.
Answer: correct choice is C.
The value of x that will make the triangles similar by SSS similarity theorem is;
x = 77.
We are told that the 2 triangles are similar by SSS theorem.
Now, SSS means Side - Side -Side and it is a congruence theorem which states that the 3 corresponding sides of two triangles have same ratio, then we can say that the two triangles are congruent by SSS theorem
Thus, in our 2 given triangles ,applying the SSS postulate gives;
x/35 = 44/20
Applying the multiplication property of equality, let us multiply both sides by 35 to get;
x = (44 * 35)/20
x = 77
Thus, in conclusion the value of x that will make the triangles similar by SSS similarity theorem is 77.

"how few colors can be used so that each room is painted a color so in which no two adjacent rooms are the same color?"
We can see here that to guarantee that no two adjacent rooms are the same color, a minimum of four colors is generally needed.
To determine the minimum number of colors needed to paint each room in a way that no two adjacent rooms have the same color, we can use a coloring algorithm known as the "Four Color Theorem." According to this theorem, it is possible to color any map on a plane using at most four colors, ensuring that no two adjacent regions have the same color.
Applying this concept to the rooms, we can conclude that a minimum of four colors is needed to satisfy the given condition. By using these four colors, we can ensure that no two adjacent rooms share the same color.

When visiting Baltimore, MD, you need to rent a taxi to get from your hotel to the National Aquarium. The taxi company charges a flat fee of $3.00 for using the taxi and $0.75 per mile. Write an equation in slope- intercept form that models this situation.
Answer:
The slope- intercept form this situation is given by y = 0.75x + 3 .
Step-by-step explanation:
The slope- intercept is given by
y = mx + c
Where m is the slope, c is the y intercept .
As given
When visiting Baltimore, MD needs taxi to get from your hotel to the National Aquarium.
The taxi company charges a flat fee of $3.00 for using the taxi and $0.75 per mile.
Let us assume that the total amount charge by the taxi be y .
Let us assume that the number of miles travelled by the taxi be x.
Than
Total amount charge by taxi = Amount charge by the taxi per miles + Flat free charge .
y = 0.75x + 3
(Here m = 0.75 and c = 3)
Therefore the slope- intercept form this situation is given by y = 0.75x + 3 .
The equation that models this situation is y = 0.75x + 3.
To write an equation in slope-intercept form that models the situation of renting a taxi in Baltimore, MD, you can use the following equation:
Total Cost (C) = (Cost per Mile) * (Number of Miles) + (Flat Fee)
In this case, the cost per mile is $0.75, and the flat fee is $3.00. So, the equation becomes:
C = 0.75x + 3.00
Here, C represents the total cost of the taxi ride, and x represents the number of miles traveled. This equation is in slope-intercept form (y = mx + b), where:
"C" is the dependent variable (y),
"x" is the independent variable (the number of miles traveled),
0.75 is the slope (m), which represents the cost per mile, and
3.00 is the y-intercept (b), which represents the flat fee.

A bag contains 5 blue balls, 4 red balls, and 3 orange balls. If a ball is picked from the bag at random, what is the probability that it is a blue ball? Answers have been rounded to the tenths place.
Answer: Hello there!
in the bag we have:
5 blue balls, 4 red balls, and 3 orange balls.
This adds up to 5 + 4 + 3 = 12 balls in total.
If we took a ball at random, the probability tath this ball is blue is equal to the quotient between the number of blue balls and the total number of balls.
this is P = 5/12 = 0.4166
now we need to round it to the tenths place, this is the first number after the decimal point, in this case, a 4.
To round it we need to see the number that is after if it is 5 or bigger we round up, if is smaller than 5 we round down. In this case, is a 1, means that we need to round down
p = 0.4
If a ball is picked from the bag at random, the probability that the ball taken was a blue ball, is equal to p = 0.4

Which of the binomials below is a factor of this trinomial?
4x2 + 20x - 24
A. x + 4
B. x + 1
C. x - 1
D. x - 4
Answer: the correct option is (C) x - 1.
Step-by-step explanation: We are given to select the correct binomial that is a factor of the following trinomial :
[tex]T=4x^2+20x-24~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
To select the factor, we need to factorize expression (i). To factorize, we need two integers with sum 20 and product -96.
From (i), we have
[tex]T\\\\=4x^2+20x-24\\\\=4x^2+24x-4x-24\\\\=4x(x+6)-4(x+6)\\\\=(x+6)(4x-4)\\\\=4(x+6)(x-1).[/tex]
So, the factors of the given trinomial are 4, (x + 6) and (x - 1).
Since 4 and ( x + 6) are not in the options, so (x - 1), is the correct binomial.
Thus, (C) is the correct option.
Which of the following are linear factors of px=x^3-2x^2-5x+6
Write the quadratic equation in factored form. Be sure to write the entire equation. x2 - 5x - 24 = 0
x² - 5x - 24 = 0
First, we have to solve the quadratic equation and find the two values of x that fit the equation.
[tex]x = \frac{5+- \sqrt{5^{2} + 4*1*24 } }{2*1} = \frac{5+- \sqrt{25 + 96} }{2} = \frac{5+- \sqrt{121} }{2} = \frac{5+-11}{2} [/tex]
There are two values of x that fit:
x₁ = (5+11)/2 = 16/2 = 8
x₂ = (5-11)/2 = -6/2 = -3
Now I can restate the original equation in terms of a product of factors, with this product being equal to zero:
(x - x₁) * (x - x₂) = 0
ANSWER (x-8) * (x+3) = 0
Now I can solve each factor by setting each one equal to zero and solving the resulting linear equations:
x - 8 = 0 or x + 3 = 0
x = 8 or x = -3
We can check that these two values are the solution to the original quadratic equation.
x² - 5x - 24 = 0
First value
8² -5*8 -24 = 0
64 - 40 -24 = 0
0 = 0 ¡Checked!
Second value
