Avni designs a game in which a player either wins or loses 4 points during each turn. Which equation
represents all numbers of points, p, a player may have after his or her first turn of the game?
O p = 4
O p = -4
O pl = 4
Op = -4
Answer:
Equation to represent all number of points = |4|
Step-by-step explanation:
We are told that a player either wins or loses 4 points during each turn. This means a player could either gain 4 points or loose 4 points. When writing this in Mathematical terms its means either -4 or +4.
Now, since possible number of turns is -4 or 4, then we can represent this with the absolute value symbol.
Thus, it's |4|

John invests $200 at 4.5% compounded annually. About how long will it take for John’s investment to double in value?
Answer:
The number of years needed is 15.75 years.
Step-by-step explanation:
The investment amount (present value) = $200
Interest rate =4.5%
Double of investment = $400
Now we have to find the time or number of years in which the investment amount will be doubled. So, just use the below formula to find the number of years.
Future value = present value ×(1+interest rate)^n
400 = 200×(1+4.5%)^n
N = 15.75 years
The number of years required to double the amount is 15.75 years.

Next, please write x^2 + 9 - 8x in descending powers of x:
x^2 - 8x + 9
Given segment AB with points (-4, 8) and (6, 3) respectively. Find the coordinates of point P that partitions Segment AB in the ratio 3:2. The answer should be entered in the form (x,y) with out any spaces between characters.
Answer:
The coordinates of point P are (2,5)
Step-by-step explanation:
We know that point P divides AB internally in the ratio 3:2, that is AP/PB = 3/2,
we thus use the formula for internal division.
Let A = (x₁, y₁) = (-4, 8), B = (x₂, y₂) = (6, 3) and P = (x, y)
So x = (mx₂ + nx₁)/(m + n)
y = (my₂ + ny₁)/(m + n)
where m = 3 and n = 2
Substituting the values of the x coordinates of A and B into x, we have
x = (mx₂ + nx₁)/(m + n)
x = (3 × 6 + 2 × (-4))/(3 + 2)
x = (18 - 8)/5
x = 10/5
x = 2
Substituting the values of the y coordinates of A and B into y, we have
y = (my₂ + ny₁)/(m + n)
y = (3 × 3 + 2 × 8)/(3 + 2)
y = (9 + 16)/5
y = 25/5
y = 5
Therefore, the coordinates of point P are (2,5)
Jack is running back on his football team. The first play he gained 12 yards, second play loss 15 yards, third play gained 25 yards, and fourth play loss 2 yards. What was his total gains or losses?
Answer:
20
Step-by-step explanation:
The total gains of Jack if, In the first play, he gained 12 yards, in the second play lost 15 yards, in the third play gained 25 yards, and in the fourth play lost 2 yards is 20 yards.
What is Subtraction?The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.
In math, addition is the process of adding two or more integers together. Addends are the numbers that are added, while the total refers to the outcome of the operation.
Given:
In the first play, he gained 12 yards, in the second play lost 15 yards, in the third play gained 25 yards, and in the fourth play lost 2 yards.
Assume the gains can be denoted by positive and loss by negative,
Gains = 12 yards, 25 yards.
Total gain = 12 + 25 = 37 yards
Loss = -15 yards, -2 yards
Total loss = -15 + (-2) = -17 yards
Calculate the total gain as shown below,
Total gain = total gain + total loss
Total gain = 37 + (-17)
Total gain = 20 yards.

Jamie is sewing her own dress for the school dance. She bought 2 1/4 yards of fabric. The total cost was $10. What was the cost per yard?
Answer:
$4.44
Step-by-step explanation:
Cost per yard = $10/2.25
= $4.44 (nearest cent)
the answer $ 4.44
explanation :
so first of all you need to divide 10 by 2 1/4
when you divide both number you'll get 4 4/9
4 4/9 can also be written as 4.44444444444
which is also 4.4 recurring
now we can round this off
when you round it off, you should round it off to two decimal points cause the answer should be in dollars
you should get 4.44 as an answer
so the answer will be $ 4.44

If for two non-zero vectors a,b : ∣a+b∣=∣a−b∣ then angle between them is:______a. 0b. 45c. 60d. 90
Answer:
[tex]90^\circ[/tex]
Step-by-step explanation:
Given two non zero vectors, [tex]\vec a, \vec b[/tex].
Let the angle between the two vectors = [tex]\theta[/tex]
Given that:
[tex]|\vec a+\vec b|=|\vec a-\vec b|[/tex]
Let us have a look at the formula for magnitude of addition of two vectors:
[tex]|\vec x+\vec y|=\sqrt{x^2+y^2+2xycos\theta}[/tex]
Where [tex]\theta[/tex] is the angle between the two vectors.
formula for magnitude of subtraction of two vectors:
[tex]|\vec x-\vec y|=\sqrt{x^2+y^2-2xycos\theta}[/tex]
As per the given condition:
[tex]\sqrt{a^2+b^2+2abcos\theta}=\sqrt{a^2+b^2-2abcos\theta}[/tex]
Squaring both sides:
[tex]a^2+b^2+2abcos\theta=a^2+b^2-2abcos\theta\\\Rightarrow 2abcos\theta=-2abcos\theta\\\Rightarrow cos\theta = -cos\theta\\\Rightarrow 2cos\theta = 0\\\Rightarrow cos\theta = 0\\\Rightarrow \theta = 90^\circ[/tex]
So, the angle between the two vectors is: [tex]90^\circ[/tex]

I am a real number I am a rational number I am not a natural number I am less than -13 what number am I
Answer:
Any number less than -13.
Step-by-step explanation:
If the number is real and rational and non-natural, this means that it can be any number in the negative number space.
Additionally, since the number has to be less than -13, then the number could be any number less than -13.
With all these things considered, the number is any number less than -13 that is real and rational.

*BRAINLIEST* The lines below are parallel. If the slope of the green line is 8/5, what is the slope of the red line?
Any two parallel lines always have the same slope (but different y intercepts)
The equation of the green line is y = (8/5)x+6
The equation of the red line is y = (8/5)x-3
Slope intercept form is y = mx+b with m as the slope and b as the y intercept.
The slopes must be the same so that each time the line goes up some amount, we move to the right the same amount. Think of a set of stairs to possibly visualize what I mean. If the slopes are different (even slightly), then the lines will intersect at some point and we wouldn't have parallel lines.

Answer:
$170.14
Step-by-step explanation:
4,861 / 1,000 = $4.861 per gallon
35 x $4.681 = $170.135, so you need to round up to the nearest penny

For 1000 gallons=$4861
For 1 gallon =$4861/1000
For 35 gallons=$4861/1000 x 35=170.135
