Step-by-step explanation:
it is an isoceles triangle (both legs are equally long).
that means also both base angles are equal :
angle J = angle L = 40°
the sum of all angles in a triangle is always 180°.
so,
180 = angle J + angle L + angle K = 40 + 40 + angle K
angle K = 180 - 40 - 40 = 100°

what's the GCF of 3a+5a
The common factor, in this case, is a, so the GCF is still a.
What is the greatest common factor (GCF)?
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.
To find the greatest common factor (GCF) of two or more terms, we need to factor each term and then identify the factors that are common to both terms.
In this case, we have the terms 3a and 5a. To find the GCF, we can factor each term as follows:
3a = 3a
5a = 5a
The only common factor between the two terms is a, so the GCF of 3a and 5a is a.
Alternatively, we could have written the terms as:
3a = 3 * a
5a = 5 * a
Hence, The common factor, in this case, is a, so the GCF is still a.

Which equation accurately represents this statement? Select three options. Negative 3 less than 4.9 times a number, x, is the same as 12.8. Negative 3 minus 4.9 x = 12.8 4.9 x minus (negative 3) = 12.8 3 + 4.9 x = 12.8 (4.9 minus 3) x = 12.8 12.8 = 4.9 x + 3
Option B, option C, and option E are correct because the equation is Negative 3 less than 4.9 times a number, x, which is the same as 12.8.
What is an expression?
It is defined as the combination of constants and variables with mathematical operators.
The options are:
A: -3 - 4.9x = 12.8
B: 4.9x - (-3) = 12.8
C: 3+ 4.9x = 12.8
D: (4.9 - 3)x = 12.8
E: 12.8 = 4.9x + 3
We have a statement:
A negative 3 less than 4.9 times a number, x, is the same as 12.8.
We can write in a mathematical form:
4.9x - (-3) = 12.8
or
4.9x + 3 = 12.8
or

A quadratic function y = f(x) is plotted on a graph and the vertex of the resulting parabola is (4, 6). What is the vertex of the function defined as g(x) = f(x +2) - 2?
If a quadratic function y = f(x) is plotted on a graph and the vertex of the resulting parabola is (4, 6), the vertex of the function defined as g(x) = f(x +2) - 2 is (2, 4).
How to determine the vertex of the function defined as g(x)?In Mathematics, the translation a geometric figure or graph to the left simply means subtracting a digit from the value on the x-coordinate of the pre-image while the translation a geometric figure or graph downward simply means subtracting a digit from the value on the y-coordinate (y-axis) of the pre-image.
In Geometry, the function g(x) = f(x + 2) - 2 simply means shifting a graph of the parent function by 2 units to the left and 2 units down.
In this context, we can reasonably infer and logically deduce that the vertex of the image g(x) is given by;
Vertex = (4 - 2, 6 - 2)
Vertex = (2, 4).

What is function?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.
Four main categories can be used to classify different sorts of functions. One to one function, many to one function, onto function, one to one and into function—all based on the element. A relation between a domain and range is called a function when each value in the domain only has one value in the range.

Rewrite x^2+4x−20=−8
in the form (x−p)2=q
Step-by-step explanation:
then we do the multiplications and compare :
(x - p)² = q
x² - 2px + p² = q
x² - 2px + p² - q = 0
our target is
x² + 4x - 20 = -8
x² + 4x - 12 = 0
now we compare the variable expression with the target.
x² = x² check
4x = -2px
4 = -2p
p = -2
-12 = p² - q = 4 - q
-16 = -q
q = 16
so, we have
(x - -2)² = 16
(x + 2)² = 16

What is division?
A number is divided in division, which is a straightforward procedure. The simplest way to conceptualize it is as a set of objects being distributed among a set of individuals, as in the example given above. In mathematics, division is the process of dividing a number into equal parts and calculating the maximum number of equal parts that can be made. For instance, dividing 15 by 3 results in the division of 15 into 3 groups of 5 each.
Here,
Amount added=$50
Amount already in wallet=$40
Total amount in wallet=50+40
=$90
Cost of each lunch=$4.5
Number of lunch he can buy,
=90/4.5
=20
The maximum number of lunch he can buy is 20 lunch as he has a total of $90 in his cafeteria wallet.

Find all zeros of
F(x)=x^3-7x-6
Answer:
{-2, -1, 3}
Step-by-step explanation:
You want the zeros of F(x)=x^3-7x-6.
Descartes' rule of signsThe signs of the coefficients in order of decreasing degree are +--. There is one sign change, so there is one positive real root.
Rational root theoremThe rational root theorem tells you any real roots will be divisors of the constant, 6. Hence, we only need to try ±1, ±2, ±3.
The sum of coefficients is 1-7-6 = -12, so x=1 is not a solution. The positive solution is greater than +1.
The sum of coefficients of odd-degree terms is (1 -7) = -6, equal to the sum of coefficients of even-degree terms (0 -6) = -6, so -1 is a root.
FactorizationThe attachment shows F(x) divided by the corresponding factor (x+1) using synthetic division. The quotient is (x² -x -6), so we know the factorization is ...
F(x) = (x +1)(x² -x -6) = (x +1)(x -3)(x +2)
The zero product rule tells us the roots are ...
x = {-2, -1, 3}
The graph of the function tells us the same thing.

Additional comment
The constants in the binomial factors of x² -x -6 will be factors of the constant term, -6, that sum to the linear term coefficient, -1. These are -3 and +2.

a ball is dropped from a height of 20 feet. each time it drops h feet, it rebounds 0.89h feet, 343.63 feet the total distance traveled by the ball.
What is distance?The length of the line connecting any two places is known as their distance from one another. Subtracting the different coordinates will reveal the distance if the two locations are on the same horizontal or vertical line.
h₁ = 20 feet = h
h₂ = 0.89h
h₃ = 0.89²h
h₄ = 0.89³h
...........................
h(n) = 0.89ⁿh
Therefore, total distance travelled = 20 + 2 (0.89h + 0.89²h + 0.89³h +.....)
= 20 + 2h (0.89 + 0.89² + 0.89³ +.....)
Sum of (h.p)∞ = a/ (1-r)
Where, a = first term = 0.89
r = common ratio = 0.89
