Which object has a GREATER unit rate of change as shown in the graph?
Answer: A
Step-by-step explanation:
When graphing on the complex plane , which quadrant will the complex number 10 - 13i be found in ?
Answer:
The complex number would be in the 4th quadrant.
Step-by-step explanation:
We know that a complex number is a number that can be expressed in the form of a + bi,
where
'[tex]a[/tex]' and b are real numbers, and '[tex]i[/tex] represents the imaginary unitGiven the complex number
10 - 13i
Here,
Coefficient of the real part of the complex number = 10Coefficient of the imaginary part of complex number = -13As the coefficient of the imaginary part holds a negative sign, and the real part holds a positive sign.
Thus, the complex number would be in the 4th quadrant.
A rectangular page is to contain 36 square inches of print. The margins on each side are 1 inch. Find the dimensions of the page such that the least amount of paper is used.
Given :
A rectangular page is to contain 36 square inches of print.
The margins on each side are 1 inch.
To Find :
The dimensions of the page such that the least amount of paper is used.
Solution :
Let, length and breadth of paper are x and y respectively.
Area is given by :
Area = xy ....1)
xy = 36 inch²
Now, it is given than the margins on each side is 1 inch.
So, area of paper is :
A = ( x + 2 )( y + 2 )
We want area to be minimum.
Putting value of x from 1 , we get :
A = ( 36/y + 2 )( y + 2 )
Now, differentiating above equation and equating with 0 :
[tex]3 - \dfrac{108}{y^2}=0\\\\y = \pm 6[/tex]
Now, we know dimension cannot be negative.
So, y = 6 and x = 6 .
Therefore, length and breadth are 6 and 6 inch respectively.
The length are breadth is x = 6 and y = 6 inch respectively.
Given;
Each rectangular page is to contain 36 square inches of print.
The margins on each side are 1 inch.
We have to find ;
The dimensions of the page such that the least amount of paper is used.
Therefore,
Let, length and breadth of paper are x and y respectively.
Area is given by :
Area = xy
xy = 36 inch²
Now, it is given than the margins on each side is 1 inch.
So, Area of paper is : A = ( x + 2 )( y + 2 )
We want area to be minimum.
Putting value of x from 1 , we get :
A = ( [tex]\frac{36}{y}[/tex] + 2 )( y + 2 )
Now, Differentiating above equation and equating with 0 :
[tex]3 -\frac{108}{y^{2} } = 0[/tex]
[tex]\frac{3y^{2} - 108 }{y^{2} } = 0[/tex]
[tex]3y^{2} - 108 = 0 \\3y^{2} = 108\\y^{2} = \frac{108}{3} \\y^{2} = 36\\y = 6[/tex]
then; xy = 36
6x = 36
x =[tex]\frac{36}{6}[/tex]
x = 6inches
Now, we know dimension cannot be negative.
So, y = 6 and x = 6 .
Therefore, length and breadth are 6 and 6 inch respectively.

Feliks joins a local recreation center to play basketball the reception charges $20 annual fee plus additional $15 per month for the usage of the basketball courts Feliks prepays by writing a check for 3185 for how many months did he prepays for
Answer:
211 months
Step-by-step explanation:
Feliks joins a local recreation center to play basketball the reception charges $20 annual fee plus additional $15 per month for the usage of the basketball courts Feliks prepays by writing a check for 3185 for how many months did he prepays for
Let the number of months that he prepays for be represented by m
Hence, we have the equation
$20 + $15 × m = $3185
Hence:
20 + 15m = 3185
Collect like terms
15m = 3185 - 20
15m = 3165
m = 3165/15
m = 211 months

Trey takes the angle shown, places the point of his compass on S, and draws an arc with an arbitrary radius intersecting the rays of the angle at P and R. Trey claims that as long as he draws two more arcs by placing the needle of his compass on P and then on R, drawing a ray from S through the point at which the arcs intersect, he will be able to bisect ∠S. Is Trey correct?
A. Trey is correct. Since the initial arc was drawn with the point of the compass on S, RS=PS.
B. Trey is not necessarily correct. He will need to ensure that the compass width remains the same for each arc drawn from P and R.
C. Trey is correct. Since the compass is placed on the points P and R to draw the remaining two arcs, the ray drawn through their intersection will bisect the angle.
D. Trey is not necessarily correct. He will need to ensure that the distance from S to P and the distance from S to R are equal.

Find the condition that the roots of the quadratic equation
ax2 + cx + C =0
may be in the ratio m:n
Answer:
[tex]mnb^2 = ac(m+n)^2[/tex]
Step-by-step explanation:
Given
[tex]ax^2 +bx + c = 0[/tex]
Required
Condition that the roots is in m : n
Let the roots of the equation be represented as: mA and nA
A quadratic equation has the form:
[tex]x^2 + (sum\ of\ roots)x + (product\ of\ roots)=0[/tex]
or
[tex]x^2 - (\frac{b}{a})x + \frac{c}{a} = 0[/tex]
We have the roots to be mA and nA.
So, the sum is represented as:
[tex]Sum = mA + nA[/tex]
[tex]Sum = A(m + n)[/tex]
And the product is represented as:
[tex]Product = mA * nA[/tex]
[tex]Product = mnA^2[/tex]
By comparing:
[tex]x^2 + (sum\ of\ roots)x + (product\ of\ roots)=0[/tex]
with
[tex]x^2 - (\frac{b}{a})x + \frac{c}{a} = 0[/tex]
[tex]Sum = -\frac{b}{a}[/tex]
[tex]Product = \frac{c}{a}[/tex]
So, we have:
[tex]Sum = -\frac{b}{a}[/tex]
[tex]A(m + n) = -\frac{b}{a}[/tex]
Make A the subject:
[tex]A = \frac{-b}{a(m+n)}[/tex]
[tex]Product = \frac{c}{a}[/tex]
[tex]mnA^2 = \frac{c}{a}[/tex]
Substitute [tex]A = \frac{-b}{a(m+n)}[/tex]
[tex]mn(\frac{-b}{a(m+n)})^2 = \frac{c}{a}[/tex]
[tex]mn\frac{b^2}{a^2(m+n)^2} = \frac{c}{a}[/tex]
Multiply both sides by a
[tex]a * mn\frac{b^2}{a^2(m+n)^2} = \frac{c}{a} * a[/tex]
[tex]\frac{mnb^2}{a(m+n)^2} = c[/tex]
Cross Multiply:
[tex]mnb^2 = ac(m+n)^2[/tex]
Hence, the condition that the ratio is in m:n is
[tex]mnb^2 = ac(m+n)^2[/tex]

Answer:
y= Ix-3I (that says absolute value btw)
Step-by-step explanation:
This is the result of starting with y = |x|, then shifting it three units to the right. Replacing x with x-3 moves the xy axis three units to the left, giving the illusion the V shaped curve moved 3 spots to the right.
We don't shift up or down since the vertex is on the x axis.
We also don't vertically compress or stretch the graph either.
Side note: the vertex for this graph is (3,0) which is the lowest point of the curve.
Kamal got married 5 years ago. Today his age is 1 1/4 times his age at the time of marriage. His sons age is 1/10 times his present age. What is hisson's age ?
Answer:Son's age =2.5 years old
Step-by-step explanation:
Step 1
Let the age of Kamla at marriage be represented as x
Age after five years = x+5
Given that today his age is 1 1/4 times his age at marriage, Our equation to express his age at marriage will be
x+ 5= (5/4)x
Multiplying 4 by both sides gives
4(x+5) = (5/4 x 4 )x
4x+20 = 5x
20=5x-4x
x= 20 years at Marriage
Therefore his present age = 20+5= 25
Step 2
Son' s age = 1/10 times his present age
Son's age = 1/10 x 25= 2.5 years old

Answer:
Discriminant = -92
the equation has no distinct real numbers
Step-by-step explanation:
Given the function f(x) = 4x^2 + 2x + 6 where;
a = 4, b = 2 and c= 6
The discriminant is expessed as D = b^2 - 4ac
Substitute;
D = 2^2 - 4(4)(6)
D = 4 - 96
D = -92
Hence the discriminant is -92.
Since the discriminant is less than zero i.e D< 0, this shows that the zeros of the equation are not real but complex numbers. Hence, the equation has no distinct real numbers
Answer:
-92 is the discriminant
0 real value 0's

Drake needs to drill holes in a wooden plank. The holes will have a diameter of 0.5 millimeters, with an error allowance of 0.05 millimeters. Which equation can be used to find the minimum and maximum acceptable diameters?
Answer:
|x − 0.5| = 0.05
Step-by-step explanation:
Here x represents the diameter,
Since, an error of 0.05 millimeters is allowance in diameter,
Thus, the maximum acceptable diameter = x + 0.05,
And, the minimum acceptable diameter = x - 0.05
According to the question,
The holes will have a diameter of 0.5 millimeters,
Thus, x - 0.05 < 0.5 and 0.5 < x + 0.05
⇒ x - 0.5 < 0.05 and x - 0.5 > - 0.05
⇒ x - 0.5 < 0.05 and -(x -0.5) < 0.05
⇒ |x-0.5| < 0.05
⇒ Option D is correct.
