The vertex of this parabola is at (4,-3). When the x-value is 5, the y-value is -6. What is the coefficient of the squared term in the parabola’s equation?
In parabola , the coefficient of the squared expression is -3..
What on a graph is a parabola?
Drawing a parabola for the quadratic function f(x) = ax2 + bx + c results in a U-shaped curve. When an is smaller than zero, the parabola's graph is downward (or opens downward). When the value of an is greater than 0, the parabola's graph ascends (or opens up).Parabola equation with a vertex at (h, k) is given by y = a(x - h)^2 + k
For the give parabola, y = a(x - 4)^2 - 3
y = a(x^2 - 8x + 16) - 3
At (5, -6)
-6 = a((5)^2 - 8(5) + 16) - 3 = a(25 - 40 + 16) - 3 = a - 3
a = -6 + 3 = -3
Therefore, the coefficient of the squared expression is -3..

Step-by-step explanation:
Andy and his friend sam were walking along the road together. andy had a big bag of marbles. unfortunately the bottom of the bag split and all the marbles spilled out. poor andy! one third of the marbles rolled down the slope too quickly for andy to pick them up. one sixth of all the marbles disappeared into the rain-water drain. andy and sam picked up all they could but half of the marbles that remained nearby were picked up by other children who ran off with them. andy counted all the marbles he and sam had rescued. he gave one third of these to sam for helping him pick them up. andy put his remaining marbles into his pocket. there were 14 of them. how many marbles were there in andy's bag before the bottom split?
The total number of marbles that were there in Andy's bag before the bottom split are 84 marbles.
Let, the total number of marbles Andy have in the bad in beginning = x
One third of the marbles rolled down the slope too quickly for Andy to pick them up. So we can write,
Total number of marbles Andy have now = x - (x/3)
One sixth of all the marbles disappeared into the rain-water drain. So, So we can write,
Total number of marbles Andy have now = x - (x/3) - (x/6) = (x/2)
Half of the marbles that remained nearby were picked up by other children who ran off with them. So, we can write
Total number of marbles Andy have now = (x/2) - (x/4) = (x/4)
Andy gave one third of these to Sam for helping him pick them up. So,
Total number of marbles Andy have now = (x/4) - (x/12) = (x/6)
Now, we have given that Andy have 14 marbles in the end in his pocket. On comparing it with above equation, we get
(x/6) = 14
⇒ x = 84
The total number of marbles that were there in Andy's bag before the bottom split are 84 marbles.

The diameter of the most popular brand of flying disc used in disc golf measures between 8 and 10 inches. Find the range of possible circumferences and areas for these flying discs to the nearest tenth.
The range of possible circumferences and areas for these flying discs are 25. 24 inches to 31. 42 inches and 50. 27 square inches and 78. 55 square inches respectively.
How to determine the circumferenceThe formula for circumference of a circle is expressed as;
Circumference = πd
Where;
π takes the value 3. 142d is the diameterCircumference for diameter of 8 inches
Circumference = 3. 142 × 8 = 25. 14 inches
Area = 1/ 4 πd² = 1/ 4 × 3. 142 × 8²
Area = 50. 27 square inches
Circumference for diameter of 10 inches
Circumference = 3. 142 × 10
Circumference = 31. 42 inches
Area = 1/ 4 × 3. 142 × 10²
Area = 78. 55 square inches
Thus, the range of possible circumferences and areas for these flying discs are 25. 24 inches to 31. 42 inches and 50. 27 square inches and 78. 55 square inches respectively.

The circle below is centered at (4,-1) and has a radius of 3. What is it’s equation?
The equation of the area of the circle (x - 4)^2 + (y + 1)^2 = 9, that is, option B.
The standard form of an equation of a circle is (x - h)^2 + (y - k)^2 = r^2
where, r = radius of the circle and (h, k) are the coordinates of the center of the circle.
Here, we are given that a circle is centered at (4,-1) and has a radius of 3.
Thus, r = 3
h = 4
and k = -1
Therefore, the equation of the circles will be-
(x - 4)^2 + (y - (-1))^2 = 3^2
(x - 4)^2 + (y + 1)^2 = 9
Thus, option B, (x - 4)^2 + (y + 1)^2 = 9 is the correct option.

A customer wanted to purchase a video game and realized that they were short $3.96 to be able to pay. Which value is the opposite of being short $3.96?
Using the absolute value function, the value that is the opposite of being short $3.96 is: x + 3.96.
What is the absolute value function?The absolute function is defined by:
|x| = x, x ≥ 0.|x| = -x, x < 0.It measures the distance of a point x to the origin, that is, |2| = |-2| = 2.
For this problem, the number is of $3.96, that is:

The variable y varies directly with the variable x.
If the value of x is 14, what is the value of y?
Given that the variable y varies directly with the variable x. If the value of x is 14, the value of y will be 21.
If the value of x is 14, what is the value of y?Proportional relationships are relationships between two variables where their ratios are equivalent.
A direct variation is expressed;
a ∝ b then a = kb
Where k is the proportionality constant.
Given the data in the question
a = 10b = 15k = ?First, we determine the proportionality constant.
a = kb
15 = k × 10
k = 15/10
k = 3/2
Now, if the value of x is 14, then the value of y will be;
a = kb
y = kx
y = (3/2) × 14
y = ( 3 × 14 )/2
y = 42/2

Now we have to,
→ find the value of y when x is 14.
Forming the formula,
→ k × 2 = x
→ k × 3 = y
Let's complete the given table,
→ k × 2 = x, k × 3 = y
→ 1 × 2 = 2, 1 × 3 = 3
→ 2 × 2 = 4, 2 × 3 = 6
→ 3 × 2 = 6, 3 × 3 = 9
→ 4 × 2 = 8, 4 × 3 = 12
→ 5 × 2 = 10, 5 × 3 = 15
→ 6 × 2 = 12, 6 × 3 = 18
→ 7 × 2 = 14, 7 × 3 = 21
Then the table will look like,
|| x || y |||| 2 || 3 |||| 10 || 15 |||| 14 || 21 ||Hence, y is 21 when x is 14.

How to find the nth term in the sequence

The n th term of the series is 3n where n is the term of reference
As we can see that there is constant difference in the terms
12-9=3
9-6=3
6-3=3
We are made sure that it is the arithmetic progression
Common difference is the difference that is constantly subtracted or added to each term after the first term
Thus the common difference 'd' is 3 as per the calculations above
Now the first term is 3
We know that any N th term of arithmetic progression is given by the formula
Tn= a+ (n-1)*d
where a is the first term of the progression and n is the term of reference and d is the common difference
a=3
d=3
Therefore, nth term of the series is = Tn= 3 + (n-1) *3
Tn= 3+3n-3
Tn = 3n
Hence the n th term of the series is 3n where n is the term of reference

A set of 10 scores has ss = 90. if the scores are a sample, the sample variance is ____, and if the scores are a population, the population variance is ____.
If the scores are a sample, the sample variance is 10, and if the scores are a population, the population variance is 9.
A set of 10 scores has SS = 90.
The formula in getting the population variance is
σ² = SS / N
where SS is the sum of squared deviation and N is the number of population.
Therefore, the population variance is
σ² = 90 / 10
σ² = 9
The formula in getting the sample variance is
σ² = SS /( n - 1)
where SS is the sum of squared deviation and n is the number of samples.
Therefore, the sample variance is
σ² = 90/ (10 - 1)
σ² = 90 / 9
σ² = 10
Therefore, if the scores are a sample, the sample variance is 10, and if the scores are a population, the population variance is 9.

Solution : Straight line question : y= 2x-3
Straight Line:
A straight line is just a line with no curves. So, a line that extends to both sides till infinity and has no curves is called a straight line.
Slope:
The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
Use the slope and one of the points to solve for the y-intercept (b).
One of your points can replace the x and y, and the slope you just calculated replaces the m of your equation y = mx + b. Then b is the only variable left. Use the tools you know for solving for a variable to solve for b.
Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line

The end behavior of g(x) is;Option A: As x→–∞, g(x)→–∞ and as x→∞, g(x)→–∞.
What is the End behavior of the Polynomial?
The Factor Theorem states that a function with leading coefficient a and zeros x1, x2, x3,....,xn is defined by;
g(x) = a(x - x1)(x - x2).....(x - xn)
In the given table;
f(x) = 0 for x = -4 and 12. Thus, the zeros are x1 = -4 and x2 = 12
Then the definition is;
g(x) = a(x + 4)(x - 12)
g(x) = a(x² - 8x - 48)
The end behavior is the limit of g(x) as x goes to infinity, thus:
limₓ→ ∞ g(x) = limₓ→ ∞ax² = a * ∞
Since the leading coefficient a is negative, then;
a * ∞ = - ∞
Thus, the end behavior of g(x) is; As x→–∞, g(x)→–∞ and as x→∞, g(x)→–∞.
