think about the definitions of both isosceles and equilateral triangles. would an equilateral triangle also be an isosceles? explain the reasoning behind your answer as part of your response
Any triangle with two equal sides is said to be isosceles .An equilateral triangle has congruent sides, which means that each side is the same length.
What is meant by equilateral triangle and isosceles ?Equilateral refers to a triangle with three equally-sized sides. An isosceles triangle is one that has two equal sides.
An equilateral triangle has congruent sides, which means that each side is the same length. Additionally, each inside angle is identical (60 degrees). The words "equi" and "lateral," which both denote sides, are combined to form the phrase "equilateral." As a result, an equilateral triangle is one with equal sides.
The characteristics of an isosceles triangle are as follows: There is agreement between two sides. The base of an isosceles triangle refers to the third side of the triangle, which is unequal to the other two sides. The two angles that are opposite the equal sides line up perfectly.

Explain how the graph of the function f(x) = 4^2 compares to its parent function f(x)=x^2 in terms of whether it faces up or down, has a maximum or minimum, and if it’s stretched or compressed.
The given graph of the function f (x) = 4x² will be facing up , has a minimum and it's horizontally compressed.
What is Function?
A relation between a set of inputs having one output each is called a function.
Given that;
The graph of the function f(x) = 4x² compares to its parent function
f(x) = x².
Now,
By graph we have;
Function f (x) = 4x² is facing up because it is positive function.
And, It has a minimum because any quadratic function that faces up will have a minimum.
Since, In the figure below, f(x)=4x² (red) has more slope, So it's condensed toward the y-axis.
Hence, if the coefficient is bigger than 1, then the function will be horizontally compressed.
Thus, It's horizontally compressed.
Therefore, The given graph of the function f (x) = 4x² will be facing up , has a minimum and it's horizontally compressed.

Given f(x) and g(x) = f(x + k), use the graph to determine the value of k. Two lines labeled f of x and g of x. Line f of x passes through points 0, 0 and 2, 2. Line g of x passes through points negative 4, 0 and negative 2, 2. a −4 b −2 c 2 d 4
g(x) is a translation of 4 units to the right, so the correct option is a: k = -4.
What is the value of k?
We know that:
g(x) = f(x + k)
This means that g(x) is a horizontal translation of f(x) of k units.
if k > 0 the translation is to the left.
if k < 0 the translation is to the right.
We know that f(x) passes through (0, 0) and (2, 2)
so f(0) = 0
And g(x) passes through (4, 0) and (-2, 2)
This means that:
g(4) = f(0)
f(4 + k) = f(0)
4 + k = 0
k = 0 - 4 = -4
The value of k is -4, so the correct option is a.

Find all values of m for which the equation has one real solution.
(m + 1)t² + 5 = -6t
Answer:
m = [tex]\frac{4}{5}[/tex]
Step-by-step explanation:
given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
then the nature of the roots can be found using the discriminant
Δ = b² - 4ac
• if b² - 4ac > 0 then roots are real and irrational
• if b² - 4ac = 0 then the roots are real and equal
• if b² - 4ac < 0 then roots are not real
For
(m + 1)t² + 5 = - 6t ( add 6t to both sides )
(m + 1)t² + 6t + 5 = 0 ← in standard form
with a = m + 1 , b = 6 , c = 5
for the equation to have only one solution then
b² - 4ac = 0
6² - 4 × (m + 1) × 5 = 0
36 - 20(m + 1) = 0 ( subtract 36 from both sides )
- 20(m + 1) = - 36 ( divide both sides by - 20 )
m + 1 = [tex]\frac{-36}{-20}[/tex] = [tex]\frac{9}{5}[/tex] ( subtract 1 from both sides )
m = [tex]\frac{4}{5}[/tex]
a shade of paint, Orange mango can be made by mixing red paint and yellow paint in the ratio 2:5 Teddy has 20 litres of red paint and 40 litres of yellow paint
Using the ratio of 2:5 to make the shade, we need 5.7L of red paint and 28.6L of yellow paint.
What is RatioA ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls.
We use the ratio formula while comparing the relationship between two numbers or quantities. The general form of representing a ratio of between two quantities say 'a' and 'b' is a: b, which is read as 'a is to b'.
This is basically a fraction that represents the number of times a quantity is greater or less than another.
To make the orange shade, we simply need to add them in ratio of 2:5. This has to be solved using the fraction and ratio.

how do you know this is true...........
To know if the equation of this line k(x) = 3x - 6 is true, you should determine its slope and then write the equation in slope-intercept form.
What is y-intercept?In Mathematics, the y-intercept of any graph generally occur at the point where the value of "x" is equal to zero (x = 0), which is -6 in this scenario.
How to calculate the slope and equation of this line?Mathematically, the slope-intercept form of a line can be calculated by using this equation:
y = mx + c
Where:
m represents the slope of a line.x and y are the points on a graph.c represents the y-intercept.Making slope (m) the subject of formula, we have the following:
Slope, m = (y - c)/x
Slope, m = (0 - (-6))/2
Slope, m = (0 + 6)/2
Slope, m = 6/2
Slope, m = 3.
For the equation of this line, we have the following:

What is Geometric sequence?
An sequence has the ratio of every two successive terms is a constant, is called a Geometric sequence.
Given that;
In a geometric sequence,
The third term is 100 and the eighth term is 3.125.
Now,
We know that;
The nth term of geometric sequence is,
⇒ [tex]T_{n} = a r^{n - 1}[/tex]
Hence, The third term is;
⇒ [tex]T_{3} = a r^{3 - 1} = 100[/tex]
⇒ [tex]a r^{2} = 100[/tex] ..(i)
And, The eighth term is,
⇒ [tex]T_{8} = a r^{8 - 1} = 3.125[/tex]
⇒ [tex]a r^{7} = 3.125[/tex] ..(ii)
Divide equation (ii) by (i), we get;
⇒ ar⁷ / ar² = 3.125/100
⇒ r⁷ / r² = 3125 / 100000
⇒ r⁷⁻² = 3125 / 100000
⇒ r⁵ = 3125 / 100000
⇒ r = 5/10
Thus, The common ratio of a geometric sequence will be;

8 (4-a)=2a
Answer:
answer is 3.2
Step-by-step explanation:
Simplifying
8[4 + -1a] = 2a
[4 * 8 + -1a * 8] = 2a
[32 + -8a] = 2a
Solving
32 + -8a = 2a
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-2a' to each side of the equation.
32 + -8a + -2a = 2a + -2a
Combine like terms: -8a + -2a = -10a
32 + -10a = 2a + -2a
Combine like terms: 2a + -2a = 0
32 + -10a = 0
Add '-32' to each side of the equation.
32 + -32 + -10a = 0 + -32
Combine like terms: 32 + -32 = 0
0 + -10a = 0 + -32
-10a = 0 + -32
Combine like terms: 0 + -32 = -32
-10a = -32
Divide each side by '-10'.
a = 3.2
Simplifying
a = 3.2
Answer:
a = 3.2
Step-by-step explanation:
if the linear equation is: 8 (4-a)=2a the value of a would be 3.2 because
a = 16/5 which equals to 3 1/5 which is the same as 3.2
