A= {1,3,7,9,10}
B= {2,5,7,8,9,10}
Answer:
{7,9,10}
Step-by-step explanation:
(A U B) ∩ (A ∩ B)
(A U B): {1,3,7,9,10} U {2,5,7,8,9,10} = {1,2,3,5,7,8,9,10}
(A ∩ B): {1,3,7,9,10} ∩ {2,5,7,8,9,10} = {7,9,10}
(A U B) ∩ (A ∩ B): {1,2,3,5,7,8,9,10} ∩ {7,9,10} = {7,9,10}

If a1=5 and an= -5an-1 then find the value of a5.
Answer:
The value of a5 is 3125
Step-by-step explanation:
Recursive Sequence
It refers to the sequences where each term is given as a rule that depends on one or more of the previous terms, unlike explicit sequences where a general term is given and we can calculate any term without knowing the value of the previous terms, except for the first one.
The sequence is given as:
[tex]a_1=5[/tex]
[tex]a_n=-5a_{n-1}[/tex]
To find the value of a5, we need to find the previous terms first:
[tex]a_2=-5a_{1}=-5*5=-25[/tex]
[tex]a_3=-5a_{2}=-5*(-25)=125[/tex]
[tex]a_4=-5a_{3}=-5*125=-625[/tex]
[tex]a_5=-5a_{4}=-5*(-625)=3125[/tex]
The value of a5 is 3125

I JUST NEED 4 PLS!!!!!!
IM REDOING THIS SO THERE IS WRITING ON THE PAPER!!
I WILL MARK BRAINLIEST!
Answer:
C
Step-by-step explanation:
When doing 4 divided by 2 you get 2. Looking at the sign it is saying 3 is greater than the number we solve for. Since we solved and got 2 we can double check and ask is 3 greater than 2? Yes it is so that would make the statement correct.
Hope this Helps :)

Jason and Bailey found a venue for their wedding. The venue requires a $500 deposit to hold the venue for a certain date. If this was 10% of the cost of the venue, how much will Jason and Bailey pay for the venue?
Answer:
$5,000Step-by-step explanation:
Step one:
given
initial deposite= $500
10% of the venue is $500
let the cost of the venue be x
Required
cost of the venue
10/100*x=500
0.1x=500
divide both sides by 0.1
x=500/0.1
x=$5000
Therefore the cost of the venue is $5,000
The sales tax in one state is 5%. Write a function rule for finding the total cost of an item with selling price x. Then find the total cost of a CD player with a selling price of $110.
A. FX) 1.05x; $115.50
B. f(x) = 0.05x; $5.50
C. FX) 5 + x;$111.05
D. f(x) = x - 5; $108.95
Answer:
f(x) = .05x; $5.50
Step-by-step explanation:
f(x) = .05x
f(110) = .05(110) = $5.50

x/15 = 20/100
15 x 20 = 300
divide 300 by 100
that equals 3
15 - 3 = 12
Answer
12?
Step-by-step explanation:
since this is a percent deal I would a simple trick
x/15 = 20/100
15 x 20 = 300
divide 300 by 100
that equals 3
15 - 3 = 12

Determine if segments AB and CD are parallel, perpendicular, or neither. AB formed by A(3,8) and B(-6,5) CD formed by C(-6,7) and D(-3,8)
Answer:
They are parallel
Step-by-step explanation:
(3,8)(-6,5): do sloe formula (y1-y2 over x2-x1)
AB: 1/3 slope (Full formula y=1/3x+7)
(-6,7)(-3,8) ---> 8-7 over -3-(-6) = 1/3
CD: 1/3 slope (Full formula y=1/3x +9)
They have the same slope so they are parallel

Answer:
The values of k that make the given equation having imaginary roots are:
k < -18, or (-∞,-18).
Step-by-step explanation:
Nature of the Roots of a Quadratic Equation
The standard representation of a quadratic equation is:
[tex]ax^2+bx+c=0[/tex]
where a,b, and c are constants.
Solving with the quadratic formula:
[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
The expression:
[tex]d=b^2-4ac[/tex]
Is called the discriminant. The discriminant determines the nature of the roots of a quadratic equation as follows:
If d=0, there is only one real root.
if d>0, there are two different real roots
if d<0, there are two different imaginary (complex) roots
We are given the equation:
[tex]-2x^2+12x+k=0[/tex]
Comparing with the standard quadratic equation, we have:
a=-2, b=12, c=k
Calculating the discriminant:
[tex]d=12^2-4(-2)k[/tex]
[tex]d=144+8k[/tex]
If the equation has imaginary roots, then d<0, thus:
144 + 8k < 0
Subtracting 144:
8k < -144
Dividing by 8:
k < -18
The values of k that make the given equation having imaginary roots are: k < -18, or (-∞,-18).
(2x + 3y) + (4x - 3y) = 11+(-5)
Which of the following is equivalent to the equation above?
A. 6x=10
B. 6x=16
C. 6x+6y=6
D. 6x+6y=16
Answer:
The correct option should have been [tex]6x=6[/tex].
Step-by-step explanation:
Given the expression
[tex]\left(2x\:+\:3y\right)\:+\:\left(4x\:-\:3y\right)\:=\:11+\left(-5\right)[/tex]
solving the expression
[tex]\left(2x\:+\:3y\right)\:+\:\left(4x\:-\:3y\right)\:=\:11+\left(-5\right)[/tex]
Remove parentheses: (a) = a
[tex]2x+3y+4x-3y=11-5[/tex]
Group like terms
[tex]3y-3y+2x+4x=11-5[/tex]
Add similar elements
[tex]6x=6[/tex]
It is clear that not a single given option is [tex]6x=6[/tex]. It means no option is correct. It seems you mistyped the correct options.
The correct option should have been [tex]6x=6[/tex].
Each lap around the park is 0.58 mile. Jessica walked 3.25 laps around the park. How many miles did Jessica walk around the park?
Answer:
5 miles but she did walk part of another mile so that would be 5.35.
Step-by-step explanation:
you can take 3.25 and subtract that by 0.58 until you can't do it anymore. Also I didn't know if you wanted the exact amount which would be 5.35 but total miles is only 5. Hope this helps!

The volume of a fish tank is given by the function V(x)=(x+7)(x-4)(x+3). Write a function describing a fish tank that has the same height but is longer in length by 3 units and wider by 2 units.
Answer:
V(x)=(x+9) * (x-4) * (x+6)
Step-by-step explanation:
A fish tank is normally in the shape of a rectangular prism. The volume of a rectangular prism can be calculated using the following formula
V = w * h * l
where w represents the width, h represents the heigh, l represents the length, and V represents the volume of the rectangular prism/fish tank. Therefore, we can use the function provided in the question and simply add 3 units to the length and 2 units to the width in order for it to work for our new fish tank.
V(x)=(x+9) * (x-4) * (x+6)

A local florist charges $15 for delivery plus $2.75 per flower for all flower arrangements. When Marcus got the bill for a flower arrangement he ordered, it was less than $50. Which of the following could not represent the number of flowers in the arrangement Marcus ordered?
Answer:
Step-by-step explanation:
Step one:
given
All Charges
$15 for delivery
and $2.75 per flower
let the number of flowers delivered be x
and the total charges for x flowers be y
the linear function for the total charges is
y=2.75x+15
Step two:
when y=$50
50=2.75x+15
50-15=2.75x
35=2.75x
divide both sides by 2.75
x=35/2.75
x=12.72
Note: we are not given the options. We only solved for the flower arrangements
Therefore the number of flowers in the arrangement Marcus ordered
is 12.72 flowers
