Answer:
p v q = x < -3 or x > 3
Step-by-step explanation:
We are given
p: x < -3
q: x > 3
and we need to find p v q
v symbols represents disjunction and in simple terms it is called "or"
So, p v q represents either p holds or q holds
So, p v q = x < -3 or x > 3
[tex]x<-3 \vee x>3[/tex]

To find the nth term of a geometric series with first term 2 and common ratio 4, the formula [tex]a * r^(n-1)[/tex] is used.
For the 14th term, apply 2 * [tex]4^(13)[/tex] to get 134,217,728.
The student has asked for the rule to find the nth term of a geometric series and for the 14th term specifically. The first term is given as 2, and the common ratio is 4.
In a geometric series, the nth term is found using the formula[tex]a * r^(n-1)[/tex], where a is the first term and r is the common ratio. To find the 14th term, we would use the formula [tex]2 * 4^(14-1)[/tex].
Let's calculate the 14th term:
Substitute the given values into the formula: 2 * [tex]4^(13)[/tex].Calculate 4 raised to the 13th power, which is 67,108,864.Multiply this result by the first term, which is 2, to get the 14th term: 134,217,728.Therefore, the 14th term of the sequence is 134,217,728.
If m∠A = (3x-6)° and m∠B = (x + 9)°, find the m∠D.
A) 32°
B) 39°
C) 41°
D) 49°
E) None of the above
Because line BD goes through the center of the circle Angle A is a right angle which equals 90 degrees.
Set the equation for A to equal 90 and solve for x:
3x-6 = 90
Add 6 to each side:
3x = 96
Divide both sides by 3:
x = 32
Now we have a value for x , use that to solve for angle b:
B = x +9 = 32 + 9 = 41 degrees.
Now we know A and B, we can solve for D.
The three inside angles of a triangle need to equal 180.
D = 180 - 90 - 41 = 49 degrees.
The answer is D) 49

What are the solutions for x when y is equal to 0 in the following quadratic
function?
y = x ^+ 6x +12
OA) X = 3 or x = 4
OB) x= -3 or x = 4
OC) x= 3 or x = 4
OD) x= -3 or x = 4
O E) no solution
Answer:
The correct answer option is E) No solution.
Step-by-step explanation:
We are given the following quadratic equation which we are to solve for x when the value of y is 0:
[tex]y = x ^2+ 6x +12[/tex]
[tex]x ^2+ 6x +12=0[/tex]
Using the quadratic formula since there are no factors:
[tex]x=\frac{-b \pm \sqrt{b^2-4ac }}{2a}[/tex]
Substituting the values in the formula to get:
[tex]x=\frac{-6 \pm \sqrt{6^2-4(1)(12) }}{2(1)}[/tex]
[tex]x=-3+\sqrt{3}i[/tex] or [tex]x=-3-\sqrt{3}i[/tex]
There are no real number solutions to this quadratic equation.
Two numbers have a sum of 24, and 7 times the first number minus the second number is equal to 16. What is the smaller number?
Answer:
Step-by-step explanation:
Let the first number = x
Let the second number = y
x + y = 24
7x - y = 16 Add these two equations
8x = 40 Divide by 8
8x/8 = 40/8
x = 5
The smaller number will be 5
================
5 + y = 24
y = 19
==================
Proof
7*5 - 19 = 16

Answer:
Step-by-step explanation: The most important step to do is to simplify the equations down. We do this by finding common variables.
Common Variables are pairs such as 12x and 32x, and not 12x and 32y or 12 and 32.
1. [tex]12 -3y - 2x + x + 2x = 12 - 3y + x[/tex]
2. [tex]3x + 2y - 2x + y + 12 = 12 + 3y + x[/tex]
3. [tex]x + 3y + 2x - 3x + 7 + 5 = 12 + 3y[/tex]
4. [tex]12+ 3y[/tex] cannot be simplified any further.
5. [tex]12-3y+x[/tex] cannot be simplified any further.
6. [tex]5 + 2y + 7x - 4x + 3y - 17 = -12 + 5y + 3x[/tex]
7. [tex]4y + 3y + 3x - 6y - 10 - 2= -12+3x+y[/tex]
8. [tex]-12 + 3x + y[/tex] cannot be simplified any further.
9. [tex]12+ 3y + x[/tex] cannot be simplified any further.

Step-by-step explanation:By looking at the graph we observe that the graph of the function passes through the point (-4,0) , (-2,0) , (-3,-2)
A)
[tex]y=(x+4)(x+2)[/tex]
when x= -3 we have:
[tex]y=(-3+4)(-3+2)\\\\y=1\times (-1)\\\\y=-1\neq -2[/tex]
Hence, option: A is incorrect.
B)
[tex]y=x^2+3x-2[/tex]
when x= -2 we have:
[tex]y=(-2)^2+3\times (-2)-2\\\\y=4-6-2\\\\y=-4\neq 0[/tex]
Hence, option: B is incorrect.
C)
[tex]y+2=-2(x+3)^2[/tex]
when x= -2 we have:
[tex]y+2=-2(-2+3)^2\\\\y+2=-2[/tex]
[tex]y=-4\neq 0[/tex]
Hence, option: C is incorrect.
D)
[tex]y+2=2(x+3)^2[/tex]

HURRY can a triangle can be constructed with angles measuring 115°,55°, and 20°? yes or no
Answer:
no
Step-by-step explanation:
The sum of the angles of a triangle must add to 180 degrees
115+55+20 = 190
This is not equal to 180 so it is not a triangle.

No
Step-by-step explanation:
115°,55°, and 20° = 190° degrees and a triangle can only be 180° .
What is 70% of 30?
7

20
21
Answer:
D. 21
Step-by-step explanation:
Hope I helped!
Your answer is for this question is 21
1.) To find 70% percent of 30 you simply multiply both. To do that you gotta first change the percent into a decimal by moving the point two types to the left.
70 = 70.0
2.) As you can see we change the percent into a decimal.
70% = .70
3.) Now we can multiply 30 by .70 which will give us an answer of 21.

2x^2+7x=15 write in standard then factor the left side of the equation.
Answer:
see explanation
Step-by-step explanation:
Given
2x² + 7x = 15 ( subtract 15 from both sides )
2x² + 7x - 15 = 0 ← in standard form
To factorise the left side
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 2 × - 15 = - 30 and sum = + 7
The factors are + 10 and - 3
Use these factors to split the x- term
2x² + 10x - 3x - 15 ( factor the first/second and third/fourth terms )
2x(x + 5) - 3(x + 5) ← factor out (x + 5) from each term
(x + 5)(2x - 3) ← in factored form

if a polynomial function f(x) has roots 0,4,and 3+ √11,what must also be a root of f(x) 3+i√11
Answer:
3 - [tex]\sqrt{11}[/tex]
Step-by-step explanation:
Radical roots occur in conjugate pairs.
3 + [tex]\sqrt{11}[/tex] is a root then so is 3 - [tex]\sqrt{11}[/tex]
Answer:
[tex]3-\sqrt{11}[/tex]
Step-by-step explanation:
The function [tex]f(x)[/tex] has a grade of 4, becaus it has 4 roots.
Now, if one of its roots is [tex]3+\sqrt{11}[/tex], it means there fourth is [tex]3-\sqrt{11}[/tex], because square roots have two results, one positive and one negative.
So, the function cannot have a positive square root solution and not have a negative root solution.
Therefore, the right answer is [tex]3-\sqrt{11}[/tex].
what is the 17th term in the arithmetic sequence in which a6 is 101 and a9 is 83
Answer:
35
Step-by-step explanation:
We know that the general formula for arithmetic sequence is
a_n=a_0+(n-1)d
Using the general formula, we can make equations for 6th term and 9th term
a_6=a_0+(6-1)d
a_6=a_0+5d
101=a_0+5d Eqn 1
For 9th term
a_9=a_0+(9-1)d
a_9=a_0+8d
83=a_0+5d Eqn 2
Subtracting equation 2 from equation 1
101-83=a_0+5d-(a_0+8d)
18=a_0+5d-a_0-8d
18=-3d
d= -6
Putting d=-6 in Eqn 1, we get:
101=a_0+5(-6)
101=a_0-30
a_0=101+30
a_0=131
Now that we have values of a_0, and d we can find the 17th term
a_17=a_0+(17-1)d
=131+(16)(-6)
=131-96
=35
So the 17th term is 35 ..
