Answer:
x = 35°
y = 55°
Step-by-step explanation:
60° + 50° + 2x = 180° (Sum of angles on a straight line is 180°)
2x = 180° - 110°
x = 70°/2 = 35°
2x + 2y = 180°( Sum of interior angles of a triangle is 180°)
2× 35° + 2y = 180°
70° + 2y = 180°
2y = 180° - 70°
y = 110°/2
y = 55°
Find the first five terms of the sequence of partial sums. (Round your answers to four decimal places.) [infinity] (−5)n + 1 n!
Answer:
25.0000 + -37.5000 + 66.6667 + -63.5416 + 66.6667
Step-by-step explanation:
The actual formatting of the question has been attached to this response.
From the question,
Let the sequence of terms be \(b_{n}\) i.e
\(b_{n}\) = \(\frac{(-5)^{n+1} }{n!}\)
Let the sequence of partial sums be \(S_{n}\) i.e
\(S_{n}\) = s₁ + s₂ + s₃ + . . . + sₙ
Therefore the first five terms of the sequence of partial sums will be S₅ i.e
S₅ = s₁ + s₂ + s₃ + s₄ + s₅
Where;
s₁ = b₁
s₂ = b₁ + b₂ = s₁ + b₂
s₃ = b₁ + b₂ + b₃ = s₂ + b₃
s₄ = b₁ + b₂ + b₃ + b₄ = s₃ + b₄
s₅ = b₁ + b₂ + b₃ + b₄ + b₅ = s₄ + b₅
Where;
b₁ can be found by substituting n = 1 into equation (i) as follows;
\(b_{1}\) = \(\frac{(-5)^{1+1} }{1!}\)
\(b_{1}\) = 25
\(b_{1}\) = 25.0000
Recall that
s₁ = b₁
∴ s₁ = 25.0000 to 4 decimal places
--------------------------------------------------------------------------
b₂ can be found by substituting n = 2 into equation (i) as follows;
\(b_{2}\) = \(\frac{(-5)^{2+1} }{2!}\)
\(b_{2}\) = -62.5
\(b_{2}\) = -62.5000
Recall that
s₂ = s₁ + b₂
∴ s₂ = 25.000 + -62.5000 = -37.5000
-----------------------------------------------------------------------------------------
b₃ can be found by substituting n = 3 into equation (i) as follows;
\(b_{3}\) = \(\frac{(-5)^{3+1} }{3!}\)
\(b_{3}\) = 104.1667
Recall that
s₃ = s₂ + b₃
∴ s₃ = -37.5000 + 104.1667 = 66.6667
--------------------------------------------------------------------------------
b₄ can be found by substituting n = 4 into equation (i) as follows;
\(b_{4}\) = \(\frac{(-5)^{4+1} }{4!}\)
\(b_{4}\) = -130.2083
Recall that
s₄ = s₃ + b₄
∴ s₄ = 66.6667 + -130.2083 = -63.5416
-------------------------------------------------------------------------
b₅ can be found by substituting n = 5 into equation (i) as follows;
\(b_{5}\) = \(\frac{(-5)^{5+1} }{5!}\)
\(b_{5}\) = 130.2083
Recall that
s₅ = s₄ + b₅
∴ s₅ = -63.5416 + 130.2083 = 66.6667
------------------------------------------------------------------------------
Therefore, the first five terms of the partial sum is:
25.0000 + -37.5000 + 66.6667 + -63.5416 + 66.6667

What is the probability that at least one will be a girl?
What is the probability that all four will be of the same sex?
What is the probability that not all four will be of the same sex?

Express the following ratios in their simplest form.
44cm to 1m into ratio
On solving the provided question we can say that Therefore, the ratio of 44cm to 1m expressed in its simplest form is 1:2.27.
what is ratio?In mathematics, ratios demonstrate how frequently one number is contained in another. For example, if there are 8 oranges and 6 lemons in a fruit plate, the ratio of oranges to lemons is 8 to 6. In a similar vein, the orange-to-whole-fruit ratio is 8, whereas the lemon-to-orange ratio is 6:8. A ratio is an ordered pair of integers a and b represented as a / b, where b is not zero. A ratio is an equation that equates two ratios. For example, if there is one male and three girls (for every boy she has three daughters), 3/4 are girls and 1/4 are boys.
44cm is equal to 0.44m (44cm ÷ 100cm/m).
So the ratio of 44cm to 1m can be expressed as:
0.44m : 1m
0.44m ÷ 0.44 = 1
1m ÷ 0.44 = 2.27
1 : 2.27
Therefore, the ratio of 44cm to 1m expressed in its simplest form is 1:2.27.

Find an equation of the line that passes through the point
(x, y) = (3, 1) and is
perpendicular to the line
2x + 3y = 12
Considering the definition of perpendicular line, the equation of the perpendicular line that passes through the point (x, y) = (3, 1) and is perpendicular to the line 2x + 3y = 12 is y= 3/2x -7/2.
Linear equationA linear equation o line can be expressed in the form y = mx + b
where
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.Perpendicular linePerpendicular lines are lines that intersect at right angles or 90° angles. If you multiply the slopes of two perpendicular lines, you get –1.
Equation of perpendicular line in this caseIn this case, the line is 2x+3y= 12. Expressed in the form y = mx + b, you get:
3y= 12 - 2x
y= (-2x +12)÷ 3
y= -2/3x +4
Since multiplying the slopes of two perpendicular lines, you get -1, and the line has a slope of -2/3, you get:
-2/3× slope perpendicular line= -1
slope perpendicular line= (-1)÷ (-2/3)
slope perpendicular line= 3/2
The line passes through the point (3, 1). Replacing in the expression for parallel line:
1= 3/2× (3) + b

A man gave 5/12 of his money to his son , 3/7 of the remainder to his daughter and the remaining to his wife if his wife gets rs 8700 what is the total amount
The total amount the man had = 52,200 rupees. Out of this, he gave 21,750 rupees to his son, 13,050 rupees to his daughter, and 17,400 rupees to his wife , the total amount given away by the man = 21,750 + 13,050 + 17,400 = 52,200 rupees.
A man gave 5/12 of his money to his son, 3/7 of the remainder to his daughter, and the remaining to his wife. If his wife gets Rs. 8,700, what is the total amount?
The given problem can be solved using the concept of ratios and fractions. Let us solve the problem step-by-step.Assume the man had x rupees with him.The man gave 5/12 of his money to his son.
The remaining amount left with the man = x - 5x/12= (12x/12) - (5x/12) = (7x/12)The man gave 3/7 of the remainder to his daughter.'
Amount left with the man after giving it to his son = (7x/12)The amount given to the daughter = (3/7) x (7x/12)= (3x/4)The remaining amount left with the man = (7x/12) - (3x/4)= (7x/12) - (9x/12) = - (2x/12) = - (x/6) (As the man has given more money than what he had with him).
Therefore, the daughter's amount is (3x/4) and the remaining amount left with the man is (x/6).The man gave all the remaining amount to his wife.
Therefore, the amount given to the wife is (x/6) = 8700Let us find the value of x.x/6 = 8700 x = 6 x 8700 = 52,200
Therefore, the man had 52,200 rupees with him.He gave 5/12 of his money to his son. Therefore, the amount given to his son is (5/12) x 52,200 = 21,750 rupees.
The remaining amount left with the man = (7/12) x 52,200 = 30,450 rupees.He gave 3/7 of the remainder to his daughter. Therefore, the amount given to his daughter is (3/7) x 30,450 = 13,050 rupees.
The amount left with the man = (4/7) x 30,450 = 17,400 rupees.The man gave 17,400 rupees to his wife.

5.4 The graph of h(x) = f(x+ p)+q has a maximum value of 15 at x =2. Determine the values of p and q. (3
The values of p and q are p = -2 and q = 15.
To determine the values of p and q in the equation h(x) = f(x + p) + q, given that the graph of h(x) has a maximum value of 15 at x = 2, we can use this information to find the translations applied to the function f(x).
The maximum value of 15 suggests that the vertex of the graph of h(x) occurs at (2, 15).
Since the vertex is obtained by shifting the original function f(x) horizontally by p units and vertically by q units, we can conclude that p = -2 and q = 15.
When x = 2, the corresponding value of x + p is 2 + (-2) = 0.
This means that the maximum value of 15 occurs at x + p = 0, or x = -p. Therefore, we substitute x = -p = -(-2) = 2 into the equation h(x) = f(x + p) + q:
h(2) = f(2 + (-2)) + 15
h(2) = f(0) + 15
Since the maximum value of h(x) is 15, we have:
15 = f(0) + 15
Simplifying the equation, we find:
f(0) = 0
Therefore, the values of p and q are p = -2 and q = 15.
In summary, the values of p and q in the equation h(x) = f(x + p) + q, given that the graph of h(x) has a maximum value of 15 at x = 2, are p = -2 and q = 15.

4.) Probability of getting 4: 0.18 or 18%.
5.) Probability of getting 5: 0.15 or 15%.
6.) Probability of getting 6: 0.14 or 14%.
To calculate the probability of getting a specific number on a fair die, we divide the number of times that number appears by the total number of rolls. In this case, the die was rolled 100 times, and the results are given as follows:
Number: 1 2 3 4 5 6
Times: 12 16 25 18 15 14
To find the probability of getting each number, we divide the corresponding number of times by the total number of rolls (100):
Probability of getting 1 = 12 / 100 = 0.12.
Probability of getting 2 = 16 / 100 = 0.16.
Probability of getting 3 = 25 / 100 = 0.25.
Probability of getting 4 = 18 / 100 = 0.18.
Probability of getting 5 = 15 / 100 = 0.15.
Probability of getting 6 = 14 / 100 = 0.14.
Therefore, the probabilities of getting each number on a fair die, based on the given results of 100 rolls, are approximately:
1: 0.12 or 12%,
2: 0.16 or 16%,
3: 0.25 or 25%,
4: 0.18 or 18%,
