Answer:
Part 1) The diameter is [tex]D=6\ units[/tex] and the radius is equal to [tex]r=3\ units[/tex]
Part 2) The center of the circle is (1+6i)
Part 3) The point (1+9i) lies on the circle
Part 4) The point (2-i) does not lies on the circle
Step-by-step explanation:
Part 1) Show me how you would determine the length of the diameter and radius.
we have that
The circle has a diameter with end points: (4 + 6i) and (-2 + 6i)
we know that
The distance between the end points is equal to the diameter
the formula to calculate the distance between two points is equal to
[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]
(4 + 6i) ----> (4,6)
(-2 + 6i) ---> (-2,6)
substitute the values
[tex]d=\sqrt{(6-6)^{2}+(-2-4)^{2}}[/tex]
[tex]d=\sqrt{(0)^{2}+(-6)^{2}}[/tex]
[tex]d=6\ units[/tex]
therefore
The diameter is [tex]D=6\ units[/tex]
The radius is equal to [tex]r=6/2=3\ units[/tex] ---> the radius is half the diameter
Part 2) Show me how you would determine the center of the circle
we know that
The center of the circle is equal to the midpoint between the endpoints of the diameter
The circle has a diameter with end points: (4 + 6i) and (-2 + 6i)
The formula to calculate the midpoint between two points is equal to
[tex]M(\frac{x1+x2}{2},\frac{y1+y2}{2})[/tex]
substitute
[tex]M(\frac{4-2}{2},\frac{6+6}{2})[/tex]
[tex]M(1,6})[/tex]
therefore
(1,6) ----> (1+6i)
The center of the circle is (1+6i)
Part 3) Determine, mathematically, if (1+9i) lies on the circle. Show how you proved it mathematically
Find the equation of the circle
[tex](x-h)^{2}+(y-k)^{2}=r^{2}[/tex]
we have
The center is (1+6i) -----> (1,6)
r=3 units
substitute
[tex](x-1)^{2}+(y-6)^{2}=3^{2}[/tex]
[tex](x-1)^{2}+(y-6)^{2}=9[/tex]
Verify if the point (1+9i) lies on the circle
Remember that
If a point lies on the circle, then the point must satisfy the equation of the circle
Substitute the value of x and the value of y in the equation and then compare the results
we have
the point (1+9i) -----> (1,9)
[tex](1-1)^{2}+(9-6)^{2}=9[/tex]
[tex](0)^{2}+(3)^{2}=9[/tex]
[tex]9=9[/tex] -----> is true
therefore
The point (1+9i) lies on the circle
Part 4) Determine, mathematically, if (2-i) lies on the circle. Show how you proved it mathematically
The equation of the circle is equal to
[tex](x-1)^{2}+(y-6)^{2}=9[/tex]
Verify if the point (2-i) lies on the circle
Remember that
If a point lies on the circle, then the point must satisfy the equation of the circle
Substitute the value of x and the value of y in the equation and then compare the results
we have
the point (2-i) -----> (2,-1)
[tex](2-1)^{2}+(-1-6)^{2}=9[/tex]
[tex](1)^{2}+(-7)^{2}=9[/tex]
[tex]50=9[/tex] -----> is not true
therefore
The point (2-i) does not lies on the circle
To determine the length of the diameter and radius, use the distance formula. The center of the circle can be found by finding the midpoint of the diameter's end points. To determine if a point lies on the circle, use the distance formula to compare the distance between the point and the center to the radius.
Explanation:1. Determining the length of the diameter and radius:
To find the length of the diameter, we can use the distance formula. The distance between two complex numbers (a + bi) and (c + di) is given by the formula √((c-a)^2 + (d-b)^2). In this case, the two end points of the diameter are (4 + 6i) and (-2 + 6i). Using the formula, the distance is √((-2-4)^2 + (6-6)^2) = √((-6)^2 + 0) = √(36) = 6.
The radius of a circle is half the length of the diameter. Therefore, the radius of this circle is 6/2 = 3.
2. Determining the center of the circle:
The center of the circle is the midpoint between the two end points of the diameter. To find the midpoint, we can take the average of the x-coordinates and the average of the y-coordinates. In this case, the x-coordinates of the end points are 4 and -2, and the y-coordinates are 6. Taking the averages, the x-coordinate of the center is (4 + (-2))/2 = 1 and the y-coordinate of the center is (6 + 6)/2 = 6. Therefore, the center of the circle is the complex number 1 + 6i.
3. Determining if (1 + 9i) lies on the circle:
To determine if a point lies on the circle, we can check if the distance between the center of the circle and the point is equal to the radius. Using the distance formula again, the distance between the center (1 + 6i) and the point (1 + 9i) is √((1-1)^2 + (9-6)^2) = √(0 + 9) = √(9) = 3. Since the distance is equal to the radius, we can conclude that (1 + 9i) does lie on the circle.
4. Determining if (2 - i) lies on the circle:
Using the same process, we find that the distance between the center (1 + 6i) and the point (2 - i) is √((2-1)^2 + (-1-6)^2) = √(1 + 49) = √(50). Since √(50) is not equal to the radius (3), we can conclude that (2 - i) does not lie on the circle.
Write the equation of the line that passes through the points (8, -1) and (2,-5) in standard form, giver
slope form is y+1 = (x-8)
Answer:
2x - 3y = 19Step-by-step explanation:
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have the points (8, -1) and (2, -5). Substitute:
[tex]m=\dfrac{-5-(-1)}{2-8}=\dfrac{-4}{-6}=\dfrac{2}{3}[/tex]
The point-slope form of an equation of a line:
[tex]y-y_1=m(x-x_1)[/tex]
Substitute:
[tex]y-(-1)=\dfrac{2}{3}(x-8)[/tex]
[tex]y+1=\dfrac{2}{3}(x-8)[/tex] → the point-slope form
Convert to the standard form: [tex]Ax+By=C[/tex]
[tex]y+1=\dfrac{2}{3}(x-8)[/tex] multiply both sides by 3
[tex]3y+3=2(x-8)[/tex] use the distributive property a(b+c) = ab+ ac
[tex]3y+3=2x-16[/tex] subtract 3 from both sides
[tex]3y=2x-19[/tex] subreact 2x from both sides
[tex]-2x+3y=-19[/tex] change the signs
[tex]2x-3y=19[/tex] → the standard form

Answer:

we have
[tex](2-yi)^{2}[/tex]
substitute
[tex](2-yi)^{2}=(2)^{2}-2(2)(yi)+(yi)^{2}[/tex]
[tex](2-yi)^{2}=4-4yi+(y^{2})(i^{2})[/tex]
Remember that
[tex]i^{2}=-1[/tex]
substitute
[tex](2-yi)^{2}=4-4yi+(y^{2})(-1)[/tex]
[tex](2-yi)^{2}=4-4yi-y^{2}[/tex]

I’m If Linda age is decreased by 36, the result is twice Linda’s age. how old is linda?
Answer:
x=lindas age
3 times lindas age (3 time x or 3x) is decreased by 36 (-36), the result (=) is twice lindas age (2 times x or 2x)
now we have
3x-36=2x
subtract 2x
x-36=0
add 36
x=36
age=36
Step-by-step explanation:
Using algebra to solve the problem, we create the equation L - 36 = 2L, representing Linda's age. Solving for 'L', we find that Linda is 36 years old.
Explanation:This problem can be solved by using algebra, a branch of mathematics. Let's assume that Linda's age is denoted by the variable 'L'. According to the problem, if Linda's age is decreased by 36, the result is twice Linda's age. We can write this as an equation: L - 36 = 2L.
In order to solve for 'L', we'll need to get all terms involving 'L' on one side of the equation. We would then subtract 'L' from both sides, giving us -36 = L, or, re-arranged, L = 36. Therefore, Linda is 36 years old.

Write the equation of a line with slope m = 6 and including point (0, 1).
Answer:
y = 6x + 1
Step-by-step explanation:
linear equations (straight line) are expressed in the following general form:
y = mx + b, where m is the gradient and b is the y-ordinate of the point where the line crosses the y-axis (called the y-intercept)
Given : m = 6
we realize that point (0,1) is actually on the y-axis (i.e x=0), therefore this is coincidentally the y-intercept. Hence b = 1
Therefore the whole equation is
y = 6x + 1
The equation for a line is:
y = mx + c
Note:
y is the y coordinate
m is the slope
x is the x coordinate
c is the y -intercept (where the line crosses the y-axis.
The question tells us that the slope is 6 (so m is 6)
It also tells that the coordinates are: (0 , 1) (so x is 0 and y is 1)
Lets plug in these values into the equation and solve to get the missing value ( which is c) :
y = mx + c
1 = 6(0) + c
1 = c.
Now to get the equation of the line, we plug in the values for m and c into y= mx + c:
Equation of line: y = 6x + 1
-----------------------------------------------------------
Answer:
Equation of line with slop m = 6 and including point (0, 1) is:
y = 6x + 1

In 2001, a company marketed 730,000 units of its product. In 2001 its yearly volume was 50% of its volume for 2004. The 2004 volume represents how many units for each of the 365 days of 2004?
Answer:
4000 units
Step-by-step explanation:
In 2001 the total number of marketed units= 730,000
If this number represents 50% of what was marketed in 2004, then the total number of units marketed in 2004 was:
(100/50)× 730,000=1460000
To get the number for each of the 365 days in 2004 we divide the total for 2004 by 365
1460000/365= 4000 units
Answer: 4,000 units per day.
Step-by-step explanation:
You know that in 2001 its yearly volume was 50% of its volume for 2004.
Therefore, if in 2001 the company marketed 730,000 units of its product, in 2004 the volume is:
[tex]Yearly\ volume_{(2004)}=(730,000\ units)(2)=1,460,000\ units[/tex]
Let be "x" the number of units for each of the 365 days of 2004, you can find its value by dividing the 2004 volume by 365.
The result is:
[tex]units=\frac{1,460,000\ units}{365}=4,000\ units.[/tex]

A company needs to package 2400 pencils. A box in the shape of a rectangular prism can hold 60 pencils. A cylindrical container can hold 80 pencils. Each box cost the company $0.50, while each cylindrical container $0.75
Answer: A
Step-by-step explanation:
2,400 divided by 60 will give you 40. 40 multiplied by 0.50 give you $20.00.
2,400 divide by 80 will give you 30 but 30 multiplied but 0.75 gives you $22.50.
$22.50 minus $20.00 gives you $2.50
Let’s solve to answer the question.
Divide the amount of pencils the company needs by the amount of pencils the box holds.
2,400/60=40.
Now multiply it by the price.
40*.5=$20.

find the gradient of the line joining (3,7) and (6,9). Hence, find the acute angle it makes with the positive x-y axis
Answer:
33.7 degrees
Step-by-step explanation:
As we go from (3,7) to (6,9), x increases by 3 and y increases by 2. Thus, the gradient (slope) of the line connecting these two points is
m = rise / run = 2/3. Using the slope-intercept formula y = mx + b, we obtain
7 = (2/3)(3) + b, or 7 = 2 + b, so we see that b = 5 and y = (2/3)x + 5. The y-intercept is (0, 5).
Next we find the x-intercept. We set y = (2/3)x + 5 = to 0 and solve for x:
(2/3)x = -5, or (3/2)(2/3)x = -5(3/2), or x = -15/2, so that the x-intercept is
(-15/2, 0). This line intersects the x-axis at (-15/2, 0).
Now look at the segment of this line connecting (-15/2, 0) and (0, 5). Here x increases by 15/2 and y increases by 5, and so the tangent of the acute angle in question is
tan Ф = 5 / (15/2) = 10 / 15 = 2/3.
Using the inverse tangent function, we get Ф = arctan 2/3, or approx.
33.7 degrees.
I believe you meant "the acute angle it makes with the positive x-axis."
Final answer:
The gradient of the line is 2/3, and the acute angle it makes with the positive x-axis is found by taking the arctan of the gradient. which is approximately 33.69 degrees.
Explanation:
The gradient of the line joining two points, (x1, y1) and (x2, y2), is calculated using the formula:
Gradient = (y2 - y1) / (x2 - x1)
Substituting the given points (3,7) and (6,9) into the formula, we get:
Gradient = (9 - 7) / (6 - 3) = 2 / 3
The gradient is 2/3. To find the acute angle θ the line makes with the positive x-axis, we use the formula:
Tan(θ) = Gradient
So, θ = arctan(Gradient)
θ = arctan(2/3)
Calculating θ will give us the acute angle. which is approximately 33.69 degrees.

Hanging 3 washers on a spring stretches it a total of 4.5 cm. If 13 washers are placed on it instead how far will the spring stretch
Using Hooke's Law, the spring would stretch a total of 19.5 cm when 13 washers are placed on it.
To find out how much a spring would elongate when the number of washers is increased, we use Hooke's Law, which describes linear elasticity.
Since it is given that 3 washers cause the spring to stretch 4.5 cm, we can assume that each washer causes an equal amount of stretch under this elastic limit. Therefore, the amount of stretch per washer is 4.5 cm divided by 3, which is 1.5 cm per washer.
If you hang 13 washers on the spring, the total stretch can be calculated by multiplying the amount of stretch per washer with the total number of washers:
Stretch per washer × Number of washers = Total stretch
1.5 cm/washer × 13 washers = 19.5 cm.
So, with 13 washers, the spring would stretch a total of 19.5 cm.

-5 over 4 x -5 = -35 solve for x
Answer:
x = 9/7
Step-by-step explanation:
-5/4x-5 =-35
-5 = -35 * (4x-5)
-5 = -35*4x - 5*(-35)
-5 = - 140x + 175
- 140x + 175 = -5
-140x = -5 - 175 = -180
x = -180 / -140 =18 / 14 = 9 /7
To solve the given equation, -5/4x = -35, for x, you multiply both sides by the reciprocal of -5/4 which is -4/5. This gives you x = 28 as the solution.
Explanation:The given equation in your question is -5/4x = -35. In order to solve this equation for x, you would first want to isolate x on one side of the equation. Thus, we'll need to divide both sides of the equation by -5/4.
However, dividing by a fraction is the same as multiplying by its reciprocal. So, in this case, we'll multiply both sides by -4/5, which is the reciprocal of -5/4. This gives us:
x = (-35) * (-4/5)
Doing the multiplication results in x = 28.
Therefore, the solution for x in the equation is 28.

To solve x² - 12x + 36 = 90 for x, we simplify the equation to x² - 12x - 54 = 0 and use the quadratic formula to find x = 6 + 3√10 and x = 6 - 3√10.
Explanation:
To solve the equation x² - 12x + 36 = 90, we can first simplify it by subtracting 90 from both sides to set it equal to zero:
x² - 12x + 36 - 90 = 0Now we use the quadratic formula, which states that for any quadratic equation of the form ax² + bx + c = 0, the solutions for x can be found using:
x = (-b ± √(b² - 4ac)) / (2a)Applying this to our equation with a = 1, b = -12, and c = -54, we get:
x = (12 ± √((-12)² - 4*1*(-54))) / (2*1)Thus, the solutions are x = 6 + 3√10 and x = 6 - 3√10.
what expression is equivalent to 25 X 9y3
Answer:
D
Step-by-step explanation:
Use exponents property:
[tex]\dfrac{x^a}{x^b}=x^{a-b}[/tex]
1. Note that
[tex]\dfrac{x^9}{x^6}=x^{9-6}=x^3[/tex]
and
[tex]\dfrac{y^3}{y^{11}}=y^{3-11}=y^{-8}=\dfrac{1}{y^8}[/tex]
2. Now
[tex]\sqrt{25}=5\\ \\\sqrt{64}=8\\ \\\sqrt{x^3}=x\sqrt{x}\\ \\\sqrt{\dfrac{1}{y^8}}=\dfrac{1}{y^4}[/tex]
So
[tex]\sqrt{\dfrac{25x^9y^3}{64x^6y^{11}}}=\dfrac{\sqrt{25}\sqrt{x^3}}{\sqrt{64}\sqrt{y^8}}=\dfrac{5x\sqrt{x}}{8y^4}[/tex]
because [tex]x>0,\ y>0[/tex]
Answer: Last option.
Step-by-step explanation:
You need to remember the Quotient of powers property:
[tex]\frac{a^m}{a^n}=a^{(m-n)}[/tex]
Applying this property, we know that:
[tex]\sqrt{\frac{25x^9y^3}{64x^6y^{11}} }=\sqrt{\frac{25x^3}{64y^8}}[/tex]
Descompose 25 and 64 into their prime factors:
[tex]25=5*5=5^2\\64=8*8=8^2[/tex]
Since:
[tex]\sqrt[n]{a^n}=a[/tex]
And according to the Product of powers property:
[tex](a^m)(a^n)=a^{(m+n)}[/tex]
You can simplify. So, the equivalent expression is:
[tex]\sqrt{\frac{5^2x^2*x}{8^2y^8}}=\frac{5x\sqrt{x} }{8y^4}[/tex]
What is the relationship between the volume of a cone
and the volume of a cylinder? Explain.
Hello There!
The volume of a cylinder is pi * r^2 * h. It's a circle times the height.
The volume of a cone is (1/3) * pi * r^2 * h. So it is one third of the volume of a cylinder with the same dimensions.
Answer:
The volume of a cone is one-third the volume of a cylinder.
Step-by-step explanation:
If f(x) = 3x-2 and g(x)= x^2 +1, find (f+g)(x).
Answer:
It's choice D.
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
= 3x - 2 + x^2 + 1
= x^2 + 3x - 1.
Answer:
D. x^2+3x-1
Step-by-step explanation:
You have:
f(x) = 3x-2
g(x)= x^2 +1
Then:
(f+g)(x)=f(x)+g(x)
(f+g)(x)=(3x-2)+(x^2+1)
(f+g)(x)=3x-1+x^2 (-2+1=-1)
(f+g)(x)=x^2+3x-1 (ordering terms)
Which graph represents the function h(x) = –(x + 6)3 – 3?
Answer:
Step-by-step explanation:
Please, if you're indicating exponentiation, use the symbol " ^ " to indicate it. Thanks.
The parent function here is f(x) = x^3.
g(x) = (x + 6)^3 has the same graph as does
f(x) = x^3, except that the entire graph of x^3 is translated 6 units to the left.
h(x) = -(x + 6)^3 has the same graph as
does g(x), except that the entire graph of g(x) is reflected in the x-axis.
The graph of h(x) = h(x) = –(x + 6)3 – 3 is the same as that of h(x) except that the entire graph is translated downward by 3 units.
