Write an indirect proof for the following statement:
A triangle can have at most 1 obtuse angle.
We can prove that the statement is false by contradiction, as if a triangle had two obtuse angles, the sum of the measures of the internal angles of the triangle would be greater than 180º.
What is proof by contradiction?To prove an statement by contradiction, we must simply take an statement that either accepts the statement (true) or rejects (false).
An angle is classified as obtuse if it has a measure that is greater than 90º.
The sum of the measures of the internal angles of a triangle is of 180º, hence if the triangle had two obtuse angles, then the sum of the measures of the internal angles of the triangle would be greater than 180º.

As part of her retirement savings plan, Patricia deposited $200 in a bank account during her first year in the workforce. During each
subsequent year, she deposited $50 more than the previous year. Find how much she deposited during her twentieth year in the workforce.
Find the total amount deposited in the twenty years.
The amount deposited in the Patricia retirement savings plan are:
Amount deposited in the twentieth year is $1150.
Total amount deposited in time span of twenty years is $13,500.
Amount deposited by Patricia in the first year ' a₁ ' = $200
Difference between the amount deposited in the subsequent year is
'd' = $50
Amount deposited during 20th year
Let 'n' be the 20th year
The above situation represents it is arithmetic progression problem
nth term of A.P. is :
aₙ = a₁ + ( n - 1 ) d
Substitute the value we get,
a₂₀ = 200 + ( 20 - 1 ) 50
⇒ a₂₀ = 200 + 19 × 50
⇒ a₂₀ = 200 + 950
⇒ a₂₀ = $1150
Total amount deposited in twenty years
S₂₀ = (n/2) [ 2 a₁+ ( n - 1 )d ]
Substitute the value we get,
⇒S₂₀ = ( 20 /2 ) [ 2(200 ) + 19 × 50 ]
⇒ S₂₀ = 10 [ 400 + 950 ]
⇒S₂₀ = $13,500
Therefore, the amount deposited in the twentieth year is $1150 and total amount deposited in twenty years is $13,500.

the radius of a circle is increasing at a rate of 7 centimeters per minute. find the rate of change of the area when the radius is 4 centimeters.
By applying rate of change concept it can be concluded that the area will change at a rate of 176 cm² / minute.
Rate of change is the change in values of a dependent variable concerning the independent variables.
The rate of change of a function shows how the function is changing from one x value to another. Whilst, differentiation is when you have an instantaneous rate of change at a single point.
We have the following information:
The rate of change of a circle = 7 cm/minute = dr/dt
We have to find the rate of change of the circle when r = 4 cm
To do so, we will use the derivative of the circle area:
A = πr²
dA/dr = 2πr
dA/dt = dA/dr × dr/dt
= 2πr × 7
= 14πr
Now we input r = 4 cm into this equation:
rate of change of the area = 14*22/7*4
= 176 cm² / minute
Thus, when r = 4 cm, the area will change at a rate of 176 cm² / minute.

Eight bands are to perform at a weekend festival. How many different ways are there to schedule their appearances?
By using the permutation formula, it can be concluded that there are 40320 ways to schedule the bands' appearances.
Permutations are different arrangements of elements formed from n elements, taken from n or some elements. In permutation, arrangement, or order matter.
P(n,r) = n! / (n-r)! where:
n = number of objects
r = number of objects selected
If we want to know the ways to schedule the bands' appearances, it means that the arrangement matter. Thus we have to use the permutation formula:
P(n,r) = n! / (n-r)!
P(8,8) = 8! / (8 - 8)!

Answer: a - a / (7a/3 - 21b)
Step-by-step explanation:
First, let's simplify the numerator:
(a^2 - 3ab) / 3b = a^2/3b - 3ab/3b = a^2/3b - a
Next, we'll simplify the denominator:
7a - 21b = 7a/3 - 7b
Now, we can simplify the entire expression:
(a^2/3b - a) / (7a/3 - 7b) = (3b * a^2/3b - 3b * a) / (7a - 21b * 3) = a - a / (7a/3 - 21b)

7x = 490
x = 70

Using probability we know that there is a 43% chance that the 27th person in the line would be a boy.
What is probability?Probability is simply the possibility that something will happen. When we don't know how something will turn out, we can talk about the possibility of one outcome or the likelihood of several.
The study of events that fit into a probability distribution is known as statistics.
So, we know that:
The boys are 17.
The girls are 22.
Probability formula: P(E) = Favourable events/Total events
Then, the probability that the 27th person is a boy:
P(E) = Favourable events/Total events
P(E) = 17/39
P(E) = 0.43
P(E) = 43%

Write an equation of the line that passes through (-4,-1) and is perpendicular to the line y=x+6
Answer:
y = -x + 5
Step-by-step explanation:
To find the equation of the line that is perpendicular to the line y = x + 6 and passes through the point (-4, -1), we'll use the slope-point form of the equation of a line. The slope of a line perpendicular to y = x + 6 is -1, which we can find using the negative reciprocal of the slope of y = x + 6. The slope of y = x + 6 is 1. The negative reciprocal of 1 is -1.
So the equation of the line perpendicular to y = x + 6 that passes through the point (-4, -1) is given by:
y - (-1) = -1(x - (-4))
Expanding and simplifying the right-hand side, we get:
y + 1 = -x + 4

The distributive property is often used to simplify algebraic expressions.
What is algebra?Algebra refers to the involving of unknown quantities into the block relationship between variables.
In this example, the expression 2(-3x + 5) can be simplified using the distributive property. The distributive property states that for any two numbers a and b, and a third number c, a(b + c) = ab + ac. Applying this property to our expression, 2(-3x + 5) = 2(-3x) + 2(5).
By expanding the expression, we see that 2(-3x + 5) = -6x + 10. This simplified expression is much easier to work with than the original expression. The distributive property can be applied to any expression in order to simplify it, making it easier to solve.
