Answer:
(1, -1) and x= -1
Step-by-step explanation:
The vertex is (1, -1)
The parabola params are:
a=4, b=-8, c=3
v= −b/2a
- (−8)/ 2 · 4
Simplify
v=1 v=1
Plug in v=1 to find the y value
y=−1
Therefore the parabola vertex is
(1, −1)
The axis of symmetry is the line that passes through the vertex and focus.
Therefore, your axis of symmetry is
x= -1

Find the 14th term of the geometric sequence 2, 4, 8,
Answers
Answer:
16,384
Step-by-step explanation:
The pattern is times 2
2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384
The 14th term is 16384
The required 14th term of the given geometric sequence 2, 4, 8, is 16384.
What is geometric series?The geometric series defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.
The geometric sequence is given in the question as:
2, 4, 8, ...
To determine the 14th term of the geometric sequence 2, 4, 8, you can use the formula for the nth term of a geometric sequence, which is [tex]a_n = a_1 \times r^{(n-1)}[/tex], where [tex]a_n[/tex] is the nth term, [tex]a_1[/tex] is the first term, and r is the common ratio.
In this case, the first term is 2, the common ratio is 2, and the term you want to find is the 14th term, so you can plug these values into the formula to get:
[tex]a_{14} = 2 \times 2^{(14-1)}[/tex]
= 2 × 2¹³
= 2 × 8192
= 16384
Therefore, the 14th term of the geometric sequence is 16384.

Round your answer to the nearest hundredth

PLEASE HELP ME ITS DUE In 10 mins please
Answers
Answer:
Step-by-step explanation:
Part A
Since, BDFHJ is a regular pentagon,
Measure of interior angles of this pentagon = [tex]\frac{(n-2)\times 180}{n}[/tex]
= [tex]\frac{(5-2)\times 180}{5}[/tex]
= 108°
Since, ∠ABC ≅ ∠JBD [Vertical angles]
Therefore, m∠ABC = m∠JBD = 108°
Part B
m∠JBD + mCBD = 180° [Linear pair of angles]
108° + m∠CBD = 180°
m∠CBD = 180 - 108
m∠CBD = 72°
Similarly, m∠BDF + m∠CDB = 180°
m∠CDB + 108° = 180°
m∠CDB = 180 - 108
= 72°
In ΔCBD,
m∠BCD + m∠CDB + m∠DBC = 180°
m∠BCD + 72° + 72° = 180°
m∠BCD = 180° - 144°
= 36°

{ x | x < 2 or x > 8}
Answers
Answer:
{ x | x < 2 or x > 8}
Step-by-step explanation:
Given the expression
(x + 3 < 5) U (x - 7 > 1).
Solve x+3 < 5
Subtract 3 from both sides
x+3 - 3 < 5-3
x < 2
For x - 7 > 1
Add 7 to both sides
x-7+7 > 1 + 7
x > 8
Hence the union of both is { x | x < 2 or x > 8}

9x+4=180
9x = 45
X= 5
Answer:
Step-by-step explanation:
if you add all the angles in a triangle together, its 180 degrees.
so, (3x+2)+(4x+1)+(2x+1) = 180
we can combine like terms so 9x+4=180
9x=176
x=19.6 degrees
now plug the x into each angle and that's them

ground beef, how much would he pay?
Answers
Answer:
$20
Step-by-step explanation:
3 pounds of beef is 6 dollars.
6 divided by 3 is 2. Therefore, each pound cost $2.
He wants to buy 10 pounds of beef.
9 pounds would be $18.
Add 1 pound, which is $2 and you will get $20.
Therefore, he would pay $20!~

An employee does not pay tax on the first $4000 of earnings and then 25% tax on the rest of earnings. If he wants to have $20000 net of tax earnings does he need
Answers
Answer:
$68000
Step-by-step explanation:
Tax free earning = first 4000
Tax on remaining amount = 25%
Total earning in other to have $20000 net of tax earning :
Net of tax = tax free earning + (25% * remaining amount)
Let remaining amount = x
20000 = 4000 + (0.25 * x)
20000 = 4000 + 0.25x
20000 - 4000 = 0.25x
16000 = 0.25x
x = 16000 / 0.25
x = 64000
Hence,
Total earning should be :
Tax free earning + roaming amount
4000 + 64000
= $68000

B Diagonals bisect angles.
C Opposite angles are congruent.
D Diagonals are perpendicular.
E Diagonals bisect each other.
Answers
Answer:
its A, B, E AND MABEY C
Step-by-step explanation:
The statements that are true about rectangles are mentioned in options [tex](A),(B),(C),(E)[/tex] .
What are rectangles ?Rectangles a shape with four sides and having internal angles of [tex]90^0[/tex]. Two of the sides are longer than the other two. The opposite sides of the rectangle are equal in length.
Properties of Rectangle :[tex](a)[/tex] The opposite sides are equal and parallel to each other.
[tex](b)[/tex] The diagonals bisect each other but not at [tex]90^0[/tex].
[tex](c)[/tex] Diagonals are equal in length.
[tex](d)[/tex] The diagonals of rectangle are congruent.
[tex](e)[/tex] The sum of interior angles is equal to [tex]360^0[/tex] .
[tex](f)[/tex] Each interior angle is equal to [tex]90^0[/tex].
[tex](g)[/tex] The angles of a rectangle are all congruent.
[tex](h)[/tex] Opposite angles of a rectangle are congruent.
So, from the above mentioned properties we can assume that statements mentioned in options [tex](A),(B),(C),(E)[/tex] are true about rectangles.
Hence, we can say that the statements that are true about rectangles are mentioned in options [tex](A),(B),(C),(E)[/tex] .

A charge of 100 elementary charges is equivalent to?
[tex] \sf{with \: explanation \: please}[/tex]
Answers
Answer: The charge is equal to 1.602*10^(-17) C
Step-by-step explanation:
The elementary charge (the smallest charge that exists) is the charge of one proton (or the magnitude of the charge of a single electron), and it is equal to:
c = 1.602*10^(-19) C.
Where C stands for coulombs,
Then a charge of 100 elementary charges is equal to 100 times the charge of a single electron, this is:
Charge = 100*( 1.602*10^(-19) C) = 1.602*10^(-17) C
