Complete the square to rewrite y= x2 - 6x + 2 in vertex form. Then state
whether the vertex is a maximum or a minimum and give its coordinates.
Answer:
see explanation
Step-by-step explanation:
Given
y = x² - 6x + 2
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To complete the square
add/subtract ( half the coefficient of the x- term )² to x² - 6x
y = x² + 2(- 3)x + 9 - 9 + 2
= (x - 3)² - 7 ← in vertex form
with vertex = (3, - 7 ) and a = 1
Since a > 0 then vertex is a minimum
Answer:
The vertex is a minimum.

a brother is 12 years older than his sister. four years ago, the brother was 3 times as old as the sister is now. how old is the broter now? a 12 b 14 c 16 d 18
Answer:
C. 16
Step-by-step explanation:
Brother - b years now.
Sister - s years now.
A brother is 12 years older than his sister.
b - s = 12
(b - 4) - brother 4 years ago.
Four years ago, the brother was 3 times as old as the sister is now.
b - 4 = 3s
b - s = 12 ----> s = b - 12
b - 4 = 3s
b - 4 = 3(b - 12)
b - 4 = 3b - 36
36 - 4 = 3b - b
32 = 2b
b = 16
Answer:
C. 16
Step-by-step explanation:
Let the brother's age be x.
Let the sister's age be y.
x = y + 12
x - 4 = 3y
Put x as y + 12 in the second equation.
y + 12 - 4 = 3y
y + 8 = 3y
8 = 3y - y
8 = 2y
y = 4
Put y as 4 in the first equation.
x = 4 + 12
x = 16
The brother is 16 years old and the sister is 4 years old.
What is EF? Please help me on this question.
Answer:
EF = 8
Step-by-step explanation:
FD is an angle bisector and divides the opposite side of the angle into segments that are proportional to the other 2 sides, that is
[tex]\frac{DE}{DG}[/tex] = [tex]\frac{EF}{FG}[/tex] , substitute values
[tex]\frac{24}{54}[/tex] = [tex]\frac{x}{x+10}[/tex] ( cross- multiply )
54x = 24(x + 10) ← distribute
54x = 24x + 240 ( subtract 24x from both sides )
30x = 240 ( divide both sides by 30 )
x = 8
Thus EF = x = 8
Can someone help me solve one of these?
Answer:
see below
Step-by-step explanation:
When the letters are replaced and mixed between draws, the draws are independent. In that case, the probability of a sequence is the product of the probabilities of the individual letters in the sequence.
The individual probabilities are ...
D - 1/4
E - 2/4
R - 1/4
__
So, the probability for a sequence like DD is ...
p(D)·p(D) = (1/4)(1/4) = 1/16

Answer:
Step-by-step explanation:
Given sequence is -5, -1, -5, -25,..
In any arithmetic series nth term is given by a + (n-1)d
where a is the first term
and d is the common difference.
d = nth term - (n-1)th term
For the given series
a = -5
lets take nth term as 2nd term and 1st term as (n-1)th term
d = -1-(-5)= -1+5 = 84
n th term = a + (n-1)d
using the formula for nth term
4th term = 5 + (4-1)8 = 29

Bill bought 38 1/2 feet of wire fencing to put around his blueberry plants. He cut the wire into several pieces, each one measuring 5 1/2 feet. How many pieces of wire did he have after making the cuts?
Answer: 7
Step-by-step explanation:
You are given that Bill bought 38 1/2 feet of wire. Convert the mixed fraction into improper fraction.
The length L1 = 77/2
You are given that he cut the wire into several pieces, each one measuring 5 1/2 feet. Convert it too to improper fraction.
The length L2 = 11/2
To know how many number of pieces of wire he have after making the cuts, divide length L1 by length L2. That is,
L1/L2 = 77/2 ÷ 11/2
Change the division to multiplication by reciprocating 11/2 to 2/11
77/2 × 2/11 = 77/11 = 7
Therefore, he had 7 pieces of wires after making the cuts.

Coach kunal stacks all of the tennis balls in a square pyramid. The number of tennis balls, P(n), in n layers of the square pyramid is given by P(n) = P(n - 1) + n^2. Which could not be the number of tennis balls Coach Kunal has? A. 30 B. 5 C. 14 D. 9
Answer:
D. 9
Step-by-step explanation:
We are told in the question that: The number of tennis balls represented by P(n), in n layers of the square pyramid is given as
P(n) = P(n - 1) + n²
Let's take the first layer
n = 1
P(1) = P(1 - 1) + 1²
P(1) = 1 tennis ball.
It is important to note that the first layers we have one tennis ball.
Let's take the second layer
n = 2
P(2) = P(2 - 1) + 2²
P(2) = P(1) + 2²
Note that: P(1) above = 1
P(2) = 1 + 2²
P(2) = 5 tennis balls
It is important to note that the second layer we have five tennis balls
Let's take the third layer
n = 3
P(3) = P(3 - 1) + 3²
P(3) = P(3 - 1) + 3²
P(3) = P(2) + 3²
Note that: P(2) above = 5
P(3) = 5 + 3²
P(3) = 14 tennis balls
It is important to note that the second layer we have fourteen tennis balls
Let's take the fourth layer
n = 4
P(4) = P(4 - 1) + 4²
P(3) = P(4 - 1) + 4²
P(3) = P(3) + 4²
Note that: P(3) above = 14
P(3) = 14 + 4²
P(3) = 30 tennis balls
It is important to note that the fourth layer we have thirty tennis balls
Hence, the number of tennis balls from the first four layers will be: 1, 5, 14, 30,
So, the number of tennis balls that Coach Kunal could not have is 9.

The balance on Taylor's credit card is $2000. It has an interest rate of 12.5%. She wants to compare the difference between paying $75 and $100 of the monthly balance. How much does she save in interest and fees if she pays $100 instead of $75? Round to the nearest dollar. Enter your answer as a total in dollars, such as $134.
Answer: kindly check Explanation
Step-by-step explanation:
The balance on card = $2000
Interest rate = 12.5%
Therefore, monthly rate = 12.5% / 12 = 0.0104167
Paying $75 of monthly balance :
Interest amount on 2000 = 0.0104167 × 2000 = $20.83
Therefore,
Principal amount payed = 75 - 20.83 = 54.17
Balance = ($2000 + $20.83) - $75 = 1945.83
Interest on balance = 0.0104167 × 1945.83 = $20.2691
Paying $100 of monthly balance :
Interest amount on 2000 = 0.0104167 × 2000 = $20.83
Therefore,
Repayment = 100 - 20. 83 = $79.17
Balance = ($2000 + $20.83) - $100 = 1920.83
Interest on balance = 0.0104167 × 1920.83 = $20.0087
Interest saved by paying $100 instead of $75
$20.27 - $20.00 = $0.27 = 27 cent

Answer:
The roses cost Brad 9 dollars.
Step-by-step explanation:
We know that Brad bought 3 more daisies than roses. These daisies would've cost Brad 3 dollars.
15.00 - 3.00 = 12.00
Brad now has 12 dollars leftover. Now, we know that there is an equal amount of daisies and roses in addition to the 3 extra daisies. The cost of 1 daisy and 1 rose would be 4 dollars.
12.00/4.00 = 3
This means that he bought 3 of each kind of flower, and 3 extra daisies. To find out how much the 3 roses he bought cost, we lastly multiply 3 x 3.
3 x 3 = 9.
The roses cost Brad 9 dollars.
Hope this helps!

Help ASAP I need this one answered please please please
Answer:
Yes
Step-by-step explanation:
For 2 figures to be similar, the ratio of their corresponding must be the same, as well as their proportion. The simplification of their ratio gives us the scale factor of their corresponding sides. Also, their corresponding angles are congruent.
Looking at polygon LMNO and WXYZ, let's set the ratio of their corresponding side against each other to see if they would be equal to each other.
Thus, we have:
LM/XY = ON/WZ = MN/WZ = LO/ZY
35/10 = 35/10 = 63/18 = 63/18
It would give us a scale factor of 3.5
They are similar.
The answer is:
YES
LMNO ~ WXYZ
Scale factor = 3.5
How many 4-digit numbers divisible by 5, all of the digits of which are even, are there? WILL MARK BRAINLIEST NEEED ASAP
Answer:
4*5*5*2=200 numbers
Step-by-step explanation:
this is because 2,4,6,8 can be the first digit.
2,4,6,8,0 can be the second same for the third.
2 digits can be divisible by 5 which are 5, 0. If it has a 0 at the end it is divisible by 10 which means it is divisible by 5.
Answer:
100 numbers
Step-by-step explanation:
Since there are four digits, the answer will be the product of four numbers. The first digit has to be either 2,4,6, or 8 because it is a four digit number with all even digits. Same for the next two numbers, but zero is also a possibility. The question asks for a number divisible by 5, so the last digit must be a 0 in order to qualify as an even number. So the answer would be 4*5*5*1 (number of possible digits) which is 100.
