What are the 3 types of terms in quadratic equation?
The 3 types of terms in quadratic equation:
1) quadratic term,
2) linear term,
3) constant term.
We know that the second degree algebraic equation in x is a quadratic equation.
The standard form of quadrtic equation is ax^2 + bx + c = 0, where a, b, c are integers.
As thise is a quadratic equation, the value of a can not be zero. a ≠ 0
The term ax^2 is called the quadratic term.
From this term, the name given to the equation(quadrtic equation)
The term bx is called the linear term.
And the term c is called the constant term.

What is the Gamma Distribution ?
A distribution which is described as two parameters – shape parameter and inverse scale parameter, having continuous probability distributions.
Given,
Z be a standard normal random variable: i. E. , Z ∼ N(0, 1).
Using the distribution method, find the pdf of U = Z 2.
And Using result from previous part, show that pdf of U follows a special case of Gamma distribution and also of χ 2 distribution.
Suppose e Z ∼ N (0, 1), then
mZ (t) = 1√2πetxe−x2/2dx

What is the length of JL, nearest tenth
Answer:
I believe the answer is 45.
Step-by-step explanation:
a 90 degree angle is represented by a square on the corner.
So half of 90 is:
90 ÷ 2 = 45
the angle next to the letter M is 90 degreess, so the other side of the line is also 90 degrees.
45 + 90 = 135
and 180 - 135 = 45
(You subtract 135 from 180 since " the sum of angles of a triangle equals the straight angle", which is 180 degrees.
So, the length of JL is equal to 45 degrees.

The prime factor trees for 24 and 84 are attached in the image below. The Lowest Common Multiple of 24 and 84 is 168.
What are prime factors?A natural number other than 1 whose only factors are 1 and itself is said to be a prime factor. In actuality, the first few prime numbers are 2, 3, 5, 7, 11, and so forth. The lowest of two or more natural numbers' common multiples is referred to as the Lowest Common Multiple (LCM). A prime factor is a natural integer, other than 1, whose sole factors are itself and 1. Actually, 2, 3, 5, 7, 11, and so forth are the first few prime numbers. The term "Lowest Common Multiple" refers to the common multiple of two or more natural integers that is the lowest (LCM).
The prime factors of 24 are: 2,2,2 and 3.
The prime factors of 84 are: 2,2,3 and 7.
Now, The Lowest Common Multiple (LCM) of 24 and 84 is calculated using the prime factors of both the numbers.
LCM= 2*2*2*3*7= 168
Hence, The Lowest Common Multiple of 24 and 84 is 168.

a. Verify this is a Pythagorean triple.
b. Approximate the acute angles in this triangle.
A triangle has sides of 7, 24, and 25 cm. The length of the hypotenuse is equal to 25 cm if the triangle is a right triangle.
What are the angles of a 7/ 24/ 25 triangle?The triangle's sides are 7 cm, 24 cm, and 25 cm, as is obvious.
49, 576, and 625 are the results of squaring the lengths of the side of the.
49 + 576 = 625\s(7)2 + (24)2 = (25)2
As a result, the aforementioned equation satisfies Pythagoras's theorem. As a result, it is a right-angled triangle.

By solving, we see that the product of the polynomials 4 - a and a3 + 7a - 18 is a3 + 3a2 + 46a + 72.
what is polynomial ?The location on the y-axis where the slope of the line passes is known as the intersection point in mathematics. a point on a line or curve where the y-axis crosses. The equation for the straight line is given as Y = mx+c, where m denotes the slope and c the y-intercept. In the intercept form of the equation, the line's slope (m) and y-intercept (b) are highlighted. The slope and y-intercept of an equation with the intercept form (y=mx+b) are m and b, respectively. There are several equations that can be rewritten to look like slope intercepts. The slope and y-intercept are both modified to 1 if y=x is rewritten as y=1x+0, for example.
given
(4 - a) * ( a3 + 7a - 18 )
= 4a3 + 28a - 72 - a4 + 7a2 + 18 a
