Which of the following options is a polynomial with a root 2i and exactly 2
real roots?
Answer:
B. [tex]f(x)=x^4-x^3+2x^2-4x-8[/tex]
Step-by-step explanation:
If [tex]2i[/tex] is a root of f(x), then the complex conjugate [tex]-2i[/tex] is also a solution. If f(x) should have exactly 2 real roots, then by the Fundamental Theorem of Algebra, the minimum degree of f(x) is 4.
Hence the first and last options are eliminated.
By the Remainder Theorem, [tex]f(2i)=0[/tex].
Let us check for options B and C.
For option B.
[tex]f(x)=x^4-x^3+2x^2-4x-8[/tex]
[tex]\implies f(2i)=(2i)^4-(2i)^3+2(2i)^2-4(2i)-8[/tex]
[tex]\implies f(2i)=16i^4-8i^3+8i^2-8i-8[/tex]
[tex]\implies f(2i)=16+8i-8-8i-8=0[/tex]
For option C
[tex]f(x)=x^4-x^3-6x^2+4x+8[/tex]
[tex]\implies f(2i)=(2i)^4-(2i)^3-6(2i)^2+4(2i)+8[/tex]
[tex]\implies f(2i)=16i^4-8i^3-24i^2+8i+8[/tex]
[tex]\implies f(2i)=-16+8i+24+8i+8\ne0[/tex]
Therefore the correct choice is B.
Built in 1599, the Globe Theatre was home to William Shakespeare and his performing company, The Lord Chamberlain’s Men. It was a circular amphitheater that stood 3-stories tall and had a diameter of 100 feet. What formula can you use to calculate the distance around the theatre?
Answer:
C = pi * d formula
C = 314 ft
Step-by-step explanation:
To find the distance around the theatre, we want to use circumference.
C= 2 * pi *r where r is the radius
or
C = pi * d where d is the diameter
C = pi *100
C = 100pi
Using 3.14 as an approximation for pi
C = 3.14*100
C = 314 ft

Given EG = 16 and FH = 12, what is the length of one side
of the rhombus?
6 units
8 units
10 units
14 units
Answer: 10 units
Step-by-step explanation:
The length of one side of the given rhombus is; C: 10 units
What is the length of the rhombus?
The half diagonals of a rhombus are the legs of a right angle triangle with the hypotenuse being the side of the rhombus.
We see that EG and FH are the diagonals of the rhombus. This means that the half-diagonals measure 8 and 6.
Using Pythagoras theorem, we can find the hypotenuse which is the length of the side of the rhombus.
Thus;
8² + 6² = c²
64 + 36 = c²
100 = c²
c² = 100
c = 10
In conclusion, the length of one side of the rhombus is 10 units

A bucket of paint has spilled on a tile floor. The paint flow can be expressed with the function p(t) = 5t, where t represents time in minutes and p represents how far the paint is spreading.
The flowing paint is creating a circular pattern on the tile. The area of the pattern can be expressed as A(p) = πp2.
Part A: Find the area of the circle of spilled paint as a function of time, or A[p(t)]. Show your work. (6 points)
Part B: How large is the area of spilled paint after 2 minutes? You may use 3.14 to approximate π in this problem. (4 points)
Answer:
A) A(p(t)) = 25πt²
B) 314 square units.
Step-by-step explanation:
Part A)
Flow of paint can be expressed by the function:
p(t) = 5t
Area of the pattern is expressed as:
A(p) = πp²
Since area is given in terms of p, we can use the expression of p to express the area of pattern in terms of time(t). Using the value, we get:
A(p(t)) = π (5t)²
A(p(t)) = 25πt²
Part B)
We have to calculate the area of the pattern after time t. Substituting the value of t in above expression, we get:
A(p(2)) = 25 x 3.14 x 4 = 314 square units.
Therefore, the area of spilled paint after 2 minutes will be 314 square units.
Which description does NOT guarantee that a quadrilateral is a kite?
A two distinct pairs of congruent adjacent sides
B perpendicular diagonals
C perpendicular diagonals, exactly one of which bisects the other
D one diagonal bisects opposite angles and the other diagonal does not
Answer:
D one diagonal bisects opposite angles and the other diagonal does not
Option D, 'one diagonal bisects opposite angles and the other diagonal does not,' does NOT guarantee that a quadrilateral is a kite.
To determine if a quadrilateral is a kite or not based on its properties.
A quadrilateral is a kite if and only if its diagonals are perpendicular and exactly one of them bisects the other diagonal. Let's analyze the given options:
If a quadrilateral has two distinct pairs of congruent adjacent sides, it is not necessarily a kite.If a quadrilateral has perpendicular diagonals, it is one condition for it to be a kite, so this option could guarantee a kite.If a quadrilateral has perpendicular diagonals, exactly one of which bisects the other, it guarantees a kite.If one diagonal bisects opposite angles and the other diagonal does not, it is not sufficient to guarantee a kite.Therefore, option D, 'one diagonal bisects opposite angles and the other diagonal does not,' does NOT guarantee that a quadrilateral is a kite.
What is 12% of 4? Explain and Show your work
Answer:
0.48
Step-by-step explanation:
convert the percent to a decimal
12%=0.12
multiply 4 by 0.12
you're left with 0.48
you can check your math by dividing .48/.12, which will give you 4
To solve this you must use a proportion like so...
[tex]\frac{part}{whole} = \frac{part}{whole}[/tex]
12 is a percent and percent's are always taken out of the 100. This means that one proportion will have 12 as the part and 100 as the whole
We want to know what is 12% of the number 4. This means 4 is the whole and the unknown (let's make this x) is the part.
[tex]\frac{x}{4} =\frac{12}{100}[/tex]
Now you must cross multiply
x*100 = 4*12
100x = 48
Now isolate x divide 100 to both sides
100x/100 = 48/100
0.48 = x
This means that 12% of 4is 0.48

Step-by-step explanation:
Select the values that are solutions to the inequality x2 + 3x – 4 > 0.
The solutions to the inequality x^2 + 3x - 4 > 0 are all real numbers where x is less than -4 or greater than 1, represented by the intervals (x < -4) or (x > 1).
To find the values that are solutions to the inequality x2 + 3x - 4 > 0, we first need to determine the roots of the quadratic equation x2 + 3x - 4 = 0. We can do this either by factoring, completing the square, or using the quadratic formula. In this case, factoring is the simplest approach:
x2 + 4x - x - 4 = 0
(x + 4)(x - 1) = 0
Therefore, the roots are x = -4 and x = 1. Since it is a parabola opening upwards (the coefficient of x2 being positive), the inequality x2 + 3x - 4 > 0 holds true when x is either less than -4 or greater than 1.
The solution set is thus all real numbers outside the interval [-4, 1], which can be written as (x < -4) or (x > 1).
Simplify to create an equivalent expression. −y−3(−3y+5)
Answer:

Step-by-step explanation:
[tex]-y-3(-3y+5)\qquad\text{use the distributive porerty}\ a(b+c)=ab+ac\\\\=-y+(-3)(-3y)+(-3)(5)\\\\=-y+9y-15\qquad\text{combine like terms}\\\\=(-y+9y)-15\\\\=8y-15[/tex]
the simplified expression is 8y−15
To simplify the expression −y−3(−3y+5), we can start by distributing the negative sign to each term inside the parentheses.
This gives us −y+9y−15. Next, we can combine like terms by adding the coefficients of the y-terms, which gives us 8y.
Finally, we combine the constant terms to get −15.
Therefore, the simplified expression is 8y−15. We simplified the original expression by distributing the negative sign and then combining like terms to obtain a more concise and equivalent expression.

A man goes fishing in a river and wants to know how long it will take him to get 10km upstream
to his favourite fishing location. The speed of the current is 3 km/hr and it takes his boat twice
as long to go 3km upstream as is does to go 4km downstream. How long will it take his boat to
get to his fishing spot?
Answer:
Time = 25/9 hr
Step-by-step explanation:
Let speed of boat in still water is x km/hr
then, speed in downstream equals to "x + 3"km/hr
and speed in upstream equals to "x - 3" km/hr
We also know that time taken to travel 3km in upstream is twice as time taken to travel 4km in downstream.
so, using time = distance/speed
3/x- 3 = 2 × (4/x + 3)
3x + 9 = 8x -24
5x = 33
x = 33/5 km/hr
Net speed in upstream = 33/5 - 3 = 18/5 km/hr
So, Time taken to travel 10km upstream = distance /speed
= (10 × 5) / 18 = 25/9 hr
Time = 25/9 hr
The boat speed in still water is determined to be 6.6 km/hr, and it will take around 2.78 hours to travel 10 km upstream.
To determine how long it will take the man to travel 10 km upstream to his favorite fishing location, let's first define the boat speed in still water as v km/hr.
From the problem, we know:
The speed of the current is 3 km/hr.
It takes twice as long to travel 3 km upstream as it does to travel 4 km downstream.
The speed of the boat upstream relative to the shore is v - 3 km/hr, and downstream it is:
→ v + 3 km/hr.
Let t be the time it takes to travel 4 km downstream. Then time to travel 3 km upstream is 2t.
We can set up the following equations using distance = speed x time:
→ For downstream: 4 = (v + 3)t
→ For upstream: 3 = (v - 3)2t
Solve these equations:
→ From 4 = (v + 3)t, we have t = 4/(v + 3)
Substitute t in 3 = (v - 3)2t: 3 = (v - 3)2(4/(v + 3))
→ Simplify: 3(v + 3) = 8(v - 3)
→ Expand and solve for v: 3v + 9 = 8v - 24
→ 33 = 5v
→ v = 33/5
= 6.6 km/hr
Now that we know the speed of the boat in still water is 6.6 km/hr, we can determine the time it takes to travel 10 km upstream:
→ The effective speed upstream is:
= 6.6 - 3
= 3.6 km/hr.
→ Time required to travel 10 km upstream is:
= 10 / 3.6
≈ 2.78 hours.
