The sequence is an arithmetic sequence with d = 25 and the next two terms are 125, 150.
Suppose we are given a sequence: a1, a2, a3, a4, ...
To determine whether the sequence is an arithmetic, geometric, or uncategorized one, we need to check the relation between its consecutive terms.
Arithmetic sequence.
If:
a2 - a1 = a3 - a2 = a4 - a3 = constant
then the given sequence is an arithmetic sequence. Furthermore, the constant d = a2 - a1 is usually called the common difference.
Geometric sequence.
If:
a2/a1 = a3/a2 = a4/a3 = constant
then the given sequence is a geometric sequence. Furthermore, the constant r = a2/a1 is usually called the common ratio.
The given sequence is:
25,50,75,100, ........
Let us check the difference:
50 - 25 = 75 - 50 = 100 - 75 = 25.
We can, then, conclude that the sequence is an arithmetic sequence with d = 25.
To find the next two terms, add 25 to every last terms.
100 + 25 = 125
125 + 25 = 150
Hence the next two terms are: 125, 150.

Hello im sorry but I am unable to answer this.
Step-by-step explanation:
There is no parallelogram shown to answer.
Select one of the factors of x2y3 − 11x2y 6y2 − 66. (x2y 6) (x2y − 6) (y2 11) (y − 3)
A factor exists a number that completely divides another number.
The factor of x²y³ - 11x²y + 6y² - 66 is (x²y + 6)(y² - 11).
What is meant by factors?
A factor is a number that completely divides another number. To put it another way, if adding two whole numbers results in a product, then the numbers we exists adding are factors of the product because the product exists divisible by them.
By eliminating the common variables, one may get the components of the equation x²y³ - 11x²y + 6y² - 66.
x²y³ - 11x²y + 6y² - 66
Take out the common from the first two terms.
⇒ x²y(y² - 11) ..........(1)
Take out common in the last two terms.
⇒ 6 (y² - 11) ..........(2)
Adding both the equations, (1) and (2) then
[x²y(y² - 11)] + [6 (y² - 11)] = x²y(y² - 11) + 6(y² - 11)
simplifying the above equation, we get
⇒ (x²y + 6)(y² - 11)
Therefore, the factor of x²y³ - 11x²y + 6y² - 66 is (x²y + 6)(y² - 11).

The screen aspect ratio, or the ratio of the width to the height, of a high-definition television is 16:9. The size of a television is given by the diagonal distance across the screen. If an HDTV is 41 inches wide, what is its screen size?
The screen size of the HDTV is approximately 36.65 inches.
Here,
The screen aspect ratio of a high-definition television is 16:9, which means the width is 16 units and the height is 9 units.
We are given that the width of the HDTV is 41 inches.
To find the screen size, we can use the Pythagorean theorem, which states that the square of the hypotenuse (the diagonal distance across the screen) is equal to the sum of the squares of the other two sides (width and height).
Let's assume the height is h inches.
Using the Pythagorean theorem, we have:
[tex](41^2) = (16^2) + (9^2) + (h^2)[/tex]
Simplifying this equation, we get:
[tex]1681 = 256 + 81 + h^2\\1681 = 337 + h^2\\h^2 = 1681 - 337\\h^2 = 1344\\[/tex]
Taking the square root of both sides, we find:
h ≈ 36.65 inches
Therefore, the screen size of the HDTV is approximately 36.65 inches.

Find x and the measure of each side.
ΔJKL is isosceles with JK ≅ KL ,JK=4x-1,KL=2x+5 , and LJ=2x-1 .
The value of x is 3 and the measure of each side of isosceles ΔJKL is:
JK = 11
KL = 11
LJ = 5
We know that, in an isosceles triangle, any two sides of the triangle are equal and the angle opposite to these sides are equal in measure.
In this question, we have been given an isosceles ΔJKL with JK ≅ KL .
Also we have been given,
JK = 4x - 1, KL= 2x + 5 , and LJ = 2x - 1
As JK = KL
⇒ 4x - 1 = 2x + 5
⇒ 4x - 2x - 1 = 2x + 5 -2x
⇒ 2x = 5 + 1
⇒ 2x = 6
⇒ x = 3
So, the value of x is 3.
Now we find the measure of each side of triangle JKL
JK = 4x-1
JK = 4(3) - 1
JK = 12 - 1
JK = 11
Now the side KL
KL = 2x + 5
KL = 2(3) + 5
KL = 11
And LJ = 2x-1
LJ = 2(3) - 1
LJ = 5
Therefore, the value of x is 3 and the measure of each side of isosceles ΔJKL is:
JK = 11
KL = 11
LJ = 5

A football is punted into the air. Its height h, in meters, after t seconds is given by the equation h=-4.9t²+25.5t+1. Round your answer to hundredths place if needed.
1. How high is the ball after 3 seconds?
2. What is the maximum height of the ball and how many seconds will it take to reach that point?
3. How long will the ball be in the air?
Using the given quadratic function, it is found that:
1. The ball has a height of 33.4 meters after 3 seconds.
2. The maximum height of the ball is of 34.18 meters, taking 2.6 seconds to reach it's height.
3. The ball will be in the air for 5.24 seconds.
What is the quadratic equation for the ball's height?
The quadratic equation for the ball's height after t seconds is given by:
h(t) = -4.9t²+ 25.5t + 1.
Hence, after 3 seconds, the height is:
h(3) = -4.9(3)² + 25.5(3) + 1 = 33.4 meters.
The ball has a height of 33.4 meters after 3 seconds.
What is the maximum height of the ball?To find the maximum height of the ball, we have to find the vertex of the function.
What is the vertex of a quadratic equation?A quadratic equation is modeled by:
y = ax^2 + bx + c
The vertex is given by:
[tex](x_v, y_v)[/tex]
In which:
[tex]x_v = -\frac{b}{2a}[/tex][tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]Considering the coefficient a, we have that:
If a < 0, the vertex is a maximum point.If a > 0, the vertex is a minimum point.For this problem, the coefficients are given as follows:
a = -4.9, b = 25.5, c = 1.
Hence:
[tex]x_v = -\frac{25.5}{2(-4.9)} = 2.6[/tex][tex]y_v = -\frac{(25.5)^2 - 4(-4.9)(1)}{4(-4.9)} = 34.18[/tex]The maximum height of the ball is of 34.18 meters, taking 2.6 seconds to reach it's height.
How long the ball was in the air?To find how long the ball was in the air, we have to solve the quadratic equation, hence:

First of all, you refer to physics. Physicists detest miles per second estimate units. They would use meters per second (SI units),centimeters per second (CGS or less desirable SI units), or the value 1 (so-called natural units) be dependent on the type of work they are doing experimental.
Second, suppose you are mention to the condition of a vacuum. Light slows down when passing through the other a vacuum.
Third, even if physicists use miles per second as units, the values you gave are quite discrepant. The value 299 792 458 m/s is one of the values of the international system of units (SI). The speed of light is not explained to be this value, but it is a fixed value regarded as exact to be used in explain what is a meter . If in any case, it is not a calculate value and it has no uncertainty. If we do an exact conversion of this exactly value to miles per second, which is 186282 (39937/100584) m/s .
We see that, the meter per second value you stated is require, the mile per second value is only a rounded approximation and is off by about 0.15 %.
The 299 792 458 m/s value is what physicists use when they are doing calculations as part of their research, because they require the exactness. they will round off to one significant digit (actually the value is correct to three significant digits but it looks like just one) and use 300 000 000 m/s = 3 × 10⁸ m/s, which is almost trivial to multiply or divide by mentally (unlike the 186 000 mi/s) and is only 0.07 % off.
