What is the limit of a function?The limit of a function f(x) as x tends to a is the value of the function f(x) as x tends to a. It is written as [tex]\lim_{x \to a} f(x) = L[/tex]
How to find the given limit of the function?GIven that we require the limit given as [tex]\lim_{x \to 1} \frac{sinx - sin1}{x - 1}[/tex]
So, substituting the value of x = 1 into the given equation, we have that
[tex]\lim_{x \to 1} \frac{sinx - sin1}{x - 1} = \frac{sin1 - sin1}{1 - 1} \\= \frac{0}{0}[/tex]
Since 0/0 is one of the inderterminate forms, we use the L'hopital's rule to find the limit of the given function.
What is L'hopital's rule?L'hopital's rule states that if [tex]\lim_{x \to a} f(x) = \lim_{x \to a} g(x) = 0[/tex] and f'(x) and g'(x) exist then [tex]\lim_{x \to a} \frac{f(x)}{g(x)} = \lim_{x \to a} \frac{f'(x)}{g'(x)}[/tex]
Let the variables be
f(x) = sinx - sin1 and g(x) = x - 1So, since we know that
[tex]\lim_{x \to 1} \frac{sinx - sin1}{x - 1} = \frac{0}{0}[/tex],
So, [tex]\lim_{x \to a} \frac{f(x)}{g(x)} = \lim_{x \to a} \frac{f'(x)}{g'(x)}[/tex]
So, we differentiate both the numerator and denominator and find the limit.
So,
[tex]\lim_{x \to 1} \frac{f'(x)}{g'(x)} = \lim_{x \to 1} \frac{\frac{d(sinx - sin1)}{dx} }{\frac{d(x - 1)}{dx} } \\= \lim_{x \to 1} \frac{cosx - 0}{1 - 0} \\= \lim_{x \to 1}cosx \\= cos1[/tex]
So, [tex]\lim_{x \to 1} \frac{sinx - sin1}{x - 1} = cos1[/tex]

Answers in bold
GivenDefinition of complementaryGivenDefinition of congruenceVertical anglesDefinition of congruenceSubstitution propertyDefinition of complementary==============================================
Explanation:
Always start with what is given. The last statement is the thing we want to prove.
Complementary angles add to 90 degrees. They form a right angle.
When "definition of congruence" is mentioned, we go from two angles being congruent to having them be of the same measure. It's a slight change of notation.
Vertical angles form whenever we cross two lines to form an X shape. The vertical angles are opposite one another, and always congruent.
The substitution property is the idea of replacing one thing with something it is equivalent to. In other words, we plug in the item.
Notice on line 2, if we replace "angle 1" with "angle 4" (valid because the two angles are congruent), and then replace "angle 2" with "angle 3", then we get the result on line 7.
Answer:
1. Given.
2. Definition of complementary angles.
3. Given.
4. Definition of congruent angles.
5. Vertical Angles Theorem.
6. Definition of congruent angles.
7. Substitution Property of Equality.
8. Definition of complementary angles.
Step-by-step explanation:
Statement 1
∠1 and ∠2 are complementary.
Reason: Given.
Statement 2
m∠1 + m∠2 = 90°
Reason: Definition of complementary angles.
Complementary angles are two angles that sum to 90°. Therefore, if ∠1 and ∠2 are complementary, then their measures must sum to 90°.
Statement 3
∠1 ≅ ∠4
Reason: Given.
Statement 4
m∠1 = m∠4
Reason: Definition of congruent angles.
Congruent angles are angles with exactly the same measure. As angle 1 is congruent to angle 4, then their measures are equal.
Statement 5
∠2 ≅ ∠3
Reason: Vertical Angles Theorem.
Vertical angles are always congruent.
Statement 6
m∠2 = m∠3
Reason: Definition of congruent angles.
Congruent angles are angles with exactly the same measure. As angle 2 is congruent to angle 3, then their measures are equal.
Statement 7
m∠4 + m∠3 = 90°
Reason: Substitution Property of Equality.
For all numbers a and b, if a=b, then a may be replaced by b in any equation or expression.
As m∠2 = m∠3 and m∠1 = m∠4, replacing them in m∠1 + m∠2 = 90° gives m∠4 + m∠3 = 90°.
Statement 1
∠3 and ∠4 are complementary.
Reason: Definition of complementary angles.
Complementary angles are two angles whose sum is 90°. Therefore, if the sum of m∠4 and m∠3 is 90°, this means that ∠4 and ∠3 must be complementary.

Consider the function f, where f(x) = 2x2 - x+ 3. Part A Complete the equation to represent f(x + 1). X+Y Select and drag numbers into the empty boxes to correctly complete the equation.
The numeric value of the function f(x) = 2x² - x + 3 at x = x + 1 is given as follows:
f(x + 1) = 2x² + 3x + 4.
How to obtain the numeric value of a function or of an expression?To obtain the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.
In this problem, the function is defined as follows:
f(x) = 2x² - x + 3.
The point at which the numeric value is calculated as given by:
x = x + 1.
Hence the numeric value is obtaining replacing the two instances of x in the function by x + 1, as follows:
f(x + 1) = 2(x + 1)² - (x + 1) + 3
f(x + 1) = 2(x² + 2x + 1) - x - 1 + 3
f(x + 1) = 2x² + 4x + 2 - x - 1 + 3
f(x + 1) = 2x² + 3x + 4.

y = x^2 - 3x
We need to find the area between the curve y = x^2 - 3x for x between 1 and 8.
Now,
Integrate the given function:
Integration y = Integration x^2 - Integration 3x
y = [x^(2 + 1) / (2 + 1)] ^ 8 _1 - [3x^(1 + 1) / (1 + 1)] ^ 8 _1
y = [x^3 / 3] ^ 8 _1 - [3x^2 / 2] ^ 8 _1
y = [8^3 / 3 - 1^3 / 3] - [3 * 8^2 / 2 - 1 * 8^2 / 2]
y = [512 / 3 - 1 / 3] - [96 - 32]
y = 1535 / 3 - 64
y = 1535 - 192 / 3
y = 1343 / 3 square units.
So, the area is 1343 / 3 square units.
Thus, the area between the curve y = x^2 - 3x for x between 1 and 8 is 1343 / 3 square units.

HELP!!! I am having trouble understanding how to do these problems. Can someone please help explain how to complete these problems. Thank you so much!
1. Find the measure of <6.
2. Find the measure of <4.
Answer:
1=180 2=90
Step-by-step explanation:
1=∠1 and ∠2 are supplementary, so m∠2 = 180° - x°. ∠2 and ∠6 are corresponding angles. So, m∠6 = 180° - x°.
2=Their measures are equal, so m∠4 = 90 . When two lines intersect to form one right angle, they form four right angles.
Answer:
∠4 = 55°
∠6 = 35°
Step-by-step explanation:
Finding the unknown angles:In ΔABC,
35 + 90 + ∠4 = 180° {Sum of all angles of triangle}
125 +∠4 = 180
∠4 = 180 - 125
∠4 = 55°
Linear pair: If in two adjacent angles, the non-common arms form a straight line, then the two angles are called linear pair and they add up to 180.
∠7 + ∠8 = 180° {linear pair}
90 + ∠7 = 180°
∠7 = 180 - 90
∠7 = 90°
In ΔACD,
∠6 + ∠4+ ∠7 = 180 {Sum of all angles of triangle}
∠6 + 55 + 90 = 180
∠6 + 145 = 180
∠6 = 180 - 145
∠6 = 35°
Naomi is going to invest $78,000 and leave it in an account for 7 years. Assuming the
interest is compounded daily, what interest rate, to the nearest hundredth of a
percent, would be required in order for Naomi to end up with $91,000?
In order to get the total amount $91,000 at the end of the 7 year, the interest rate is 2.2% on compound interest basis.
Compound Interest:
The general form to calculate the compound interest is written as,
A = P(1 + r/n)ⁿˣ
where
A = Accrued amount (principal + interest)
P = Principal amount
r = Annual nominal interest rate as a decimal
n = number of compounding periods per unit of time
x = time in decimal years
Given,
Naomi is going to invest $78,000 and leave it in an account for 7 years. Assuming the interest is compounded daily.
Here we need to find the nearest hundredth of a percent, would be required in order for Naomi to end up with $91,000.
Here we have to solve for rate r as a decimal
[tex]r = n[(A/P)^{1/nt} - 1][/tex]
r = 365 × [(91,000.00/78,000.00)1/(365)(7) - 1]
r = 0.022022202
Then convert r to R as a percentage
R = r * 100
R = 0.022022202 * 100
R = 2.202%/year
Therefore, the interest rate required to get a total amount of $91,000.00 from compound interest on a principal of $78,000.00 compounded 365 times per year over 7 years is 2.202% per year.

write the mixed number 4 2/5 as an improper fraction
Answer:
[tex]\frac{22}{5}[/tex]
Step-by-step explanation:
To write a mixed number as an improper fraction, you start by converting the "number part" into a fraction.
For example, in this problem 4 is the number part, and we want to rewrite 4 as fraction with a denominator of 5. To do this, we multiply four by 5, which is twenty and put this over 5: [tex]\frac{20}{5}[/tex]. This would be a fraction representing 4(you can check through division).
Next, we need to add [tex]\frac{2}{5}[/tex] to this. [tex]\frac{2}{5} +\frac{20}{5}[/tex] would just be [tex]\frac{22}{5}[/tex] because 20 + 2 = 22.
