The area bounded by f(x) =sin x + 1 is 2 + π on the interval [0,pi]
What is a interval?
An interval is measured in terms of numbers. An interval includes all the numbers that come between two particular numbers. This range includes all the real numbers between those two numbersGiven that:
x-axis on the interval [0,pi]
f(x) = sin x + 1
= integral 0 - integral π (sin x) dx + integral 0 - integral π (1) dx
= [- cos π + cos 0] + [π - 0]
= [-(-1) + 1 ] + π
= 2 + π
Therefore, the area bounded by f(x) =sin x + 1 is 2 + π on the interval [0,π]

Answer:
A.) [tex]\frac{1}{5^6}[/tex]
Step-by-step explanation:
To simplify [tex](5^2)^3[/tex], use the exponent rule that states [tex](a^m)^n=a^{mn}[/tex]
So,
[tex](5^2)^3=5^{2*3}=5^6[/tex]
Use the same exponent rule to begin simplifying [tex](5^4)^{-3}[/tex]:
[tex](5^4)^{-3}=5^{4*(-3)}=5^{-12}[/tex]
To further simplify [tex]5^{-12}[/tex], use the exponent rule that states [tex]a^{-m}=\frac{1}{a^m}[/tex]
So,
[tex]5^{-12}=\frac{1}{5^{12}}[/tex]
Then multiply the two new expressions as indicated in the original problem:
[tex](5^6)(\frac{1}{5^{12}})=\frac{5^6}{5^12}=\frac{1}{5^6}[/tex]
Alternatively, you could use the exponent rule that states [tex]a^m*a^n=a^{m+n}[/tex]
where
[tex]a^m=5^6\\a^n=5^{-12}[/tex]
So,
[tex](5^6)(5^{-12})=5^{6+(-12)}=5^{-6}=\frac{1}{5^6}[/tex]

The required proof is completed by proving that triangle FCA and triangle DBE are congruent hence sides FA ≅ ED
What is congruency of triangle?Triangles are said to be congruent when the sides and angles equal in accordance to to the triangle congruency rules
Some of the rules include
Side - Side - Side = SSSSide - Angle - Side = SASAngle - Side - Angle = ASA Angle - Angle - Side = AAS Hypotenuse and one leg = HLIn the problem, since FG can safely be extended to FC also EG to EB so that
FC ≅ EB this is one side of the triangle
Similarly, AB can be extended to AC and DC to DB such that
AC ≅ DB another side of the triangle
Given that < C ≅ < B the required sides for congruency by the SAS rule is completed and thus FA = ED
The SAS rule have it that when two sides and the included angle of angle of a triangle is equal to that of another triangle then all the sides and the angels are equal therefore they are congruent triangles

if you look at the results section of a psychology research article, two signs that scores are significantly different are that (a) the error bars of the groups will not overlap, and (b) the p-value will be less than 0.05.
If Two signs that scores are significantly different then (a) the error bars of group will not overlap
Error bars are graphical representations of data variability that are used to indicate the error or uncertainty in a reported measurement on graphs.
The estimated error in a measurement is indicated by error bars. In other words, an error bar represents the degree of uncertainty in a value.
When the standard deviation error bars overlap significantly, it is an indication that the difference is not statistically significant. To reach a conclusion, you must conduct a statistical test.
When the standard deviation error bars overlap even less, it indicates that the difference is unlikely to be statistically significant.
For significantly different group , we also have p-value greater than 0.05
So, Option (b) is incorrect.
Hence, (a) The error bars of the groups will not overlap is correct

For both the experienced bricklayer and her apprentice working together it will take 2 hours to complete the work.
This is type of combined rate or time and work problem. Here, the experienced bricklayer takes 3 hours and apprentice take 6 hours to complete the job. So the experienced bricklayer completes 1/3rd of work in an hour and her apprentice completes 1/6th of work in an hour.
Let us consider they would take x hours to complete the work together. The work done is the summation of product of time taken by each person to do the work and the rate of work done by each person.

Write a recursive formula for an, the nth term of the sequence 16,-8,4
Answer: If a1 = 16 and a2 = -8, then we can write a recursive formula for the nth term of the sequence as follows:
an = a(n-1)/2
This formula states that the nth term of the sequence is equal to the previous term (n-1) divided by 2. For example, if n = 3, then a3 = a(3-1)/2 = a2/-8/2 = 4.
We can also write this formula in terms of the initial values of the sequence as follows:
a(n) = (-1)^(n-1) * 8
This formula states that the nth term of the sequence is equal to (-1) raised to the power of (n-1), multiplied by 8. This formula will always give the correct value for the nth term of the sequence, regardless of the initial values of the sequence.

Find the slope of the line y=14x–1.
Write your answer as an integer or as a simplified proper or improper fraction.
The slope of the line y = 14x – 1 is 14.
To find the slope of a line, we need to know two points on the line. We can choose any two points, as long as they are not the same. For example, we can choose the points (0, -1) and (1, 13):
y = 14x – 1
y = 14(0) – 1 = -1 when x = 0
y = 14(1) – 1 = 13 when x = 1
The slope of the line is the change in y divided by the change in x between these two points. In this case, the change in y is 13 – (-1) = 14, and the change in x is 1 – 0 = 1. Therefore, the slope of the line is 14/1 = 14.
We can also write the slope as a simplified fraction. In this case, 14 is already a simplified fraction, so we don't need to simplify further. Therefore, the slope of the line y = 14x – 1 is 14.
