Thus, the positive value of δ, the absolute value δ = 0.448 using the chain rule of differentiation, not one of the options given.
To solve for δ, we need to use the chain rule of differentiation. Starting with equation (i), we can take the derivative of both sides with respect to δ:
d/dδ(a/10) = d/dδ(7.52)
Using the chain rule, we can simplify the left side of the equation:
d/dδ(a/10) = (d/d(a/10))(a/10)' = (1/10)(a/10)'
Now we can substitute in the given value for d/dδ(a/10) and solve for (a/10)':
-33.865 = (1/10)(a/10)'
(a/10)' = -338.65
Now we can use equation (i) and substitute in the value for (a/10) and (a/10)':
7.52 = a/10
-338.65 = (a/10)'
Multiplying these equations together, we get:
-2540.468 = a'
Finally, we can use the derivative of the given equation to solve for δ:
a = 75.2δ
a' = 75.2
-2540.468 = 75.2
δ = -33.77/75.2
δ = -0.448
However, the problem asks for a positive value of δ, so we take the absolute value:
δ = 0.448
Therefore, the answer is not one of the options given in the question.

Solve the following for x, x∈W
a) 76 x 75 x 74 x ... x 6 = P(76, x)
The required value is 70. Using the permutations formula the required value is calculated. I.e., P(76, x) = P(76, 70).
How to calculate permutations?The formula for permutations is
nPr = P(n, r) = n!/(n - r)!
Where P -number of permutations,
n - number of objects in the given set
r - number of choosing objects
Calculation:The given series is
76 × 75 × 74 × ... × 6 = P(76, x)
We know that,
76! = 76 × 75 × 74 × ... × 1 ...(i)
But to get the required series,
Divide the equation (i) by 6! = (76 - 70)!
Then,
76!/(76 - 70)! = 76 × 75 × 74 × 73 ... × 6
So, x = 70.
That is,
n!/(n - r)! = P(n, r)
⇒ 76!/(76 - 70)! = P(76, 70) = 2.618743E+108
Hence the required x value is 70.

Answer:
Step-by-step explanation:
please make sure you indicate whether to factorize , simplify, fatorize by grouping , evaluate, or finding the derivative
Simplify the expression using trigonometric identities:
The simplified expression is the one in option B.
How to simplify the expression?Remember that:
[tex]sec(x) = 1/cos(x)\\\\cos(x) = cos(-x)[/tex]
With these two, we can rewrite the numerator as:
[tex]sec(x)*sin(-x) + tan(-x)\\\\\frac{1}{cos(x)}*sin(-x) + tan(x)\\\\\frac{1}{cos(-x)}*sin(-x) + tan(-x)\\\\2*tan(-x)[/tex]
Replacing that in the given expression, we have:
[tex]\frac{2*tan(-x)}{1 + sec(-x)} = \frac{2*tan(-x)}{1 + 1/cos(-x)}[/tex]
Now, if we multiply and divide by cos(-x), we get:
[tex]\frac{2*tan(-x)}{1 + 1/cos(-x)} = \frac{2*tan(-x)}{1 + 1/cos(-x)}*\frac{cos(-x)}{cos(-x)} \\\\= \frac{2*sin(-x)}{1 + cos(-x)}[/tex]
Now remember that:
[tex]cos(x) = cos(-x)\\sin(-x) = -sin(x)[/tex]
With these two properties:
[tex]\frac{2*sin(-x)}{1 + cos(-x)} = \frac{-2*sin(x)}{1 + cos(x)}[/tex]
Then the correct option is B.

Answer:
C
Step-by-step explanation:
The solution to a system equations is the point(s) of intersection of the 2 graphs.
Assuming that each square grid represents 1 unit, the coordinates of the point intersection is (-2, 2). This is because drawing a vertical line straight down from the point of intersection, we notice that the x-coordinate of the solution is 2 square units on the left of the origin. Drawing a horizontal line from the point of intersection to the y-axis gives us the y-coordinate of y= 2. Thus, the solution is (-2, 2) and the answer is C.
This method of finding the solution is also known as graphical method, where the graphs of the 2 equations are drawn, and the solution is where the lines cuts through each other.
Alternative methods of solving equations include substitution and elimination methods.
*Origin is the point (0, 0) on the graph, and it is the point in which the two axes intersect.

The four consecutive digits $a$, $b$, $c$ and $d$ are used to form the four-digit numbers $abcd$ and $dcba$. What is the greatest common divisor of all numbers of the form $abcd dcba$
1111 is the greatest common divisor of all numbers.
Lets simplify the problem,
1234 + 4321 = 5555
2345 + 5432 = 7777
3456 + 6543 = 9999
4567 + 7654 = 12221
5678 + 8765 = 14443
6789 + 9876 = 16665
After it , we get:
5555 _=_ 101 * 11 * 5
7777 = 101 * 11 * 7
9999 = 101 * 11 * 3 * 3
12221 = 101 * 11 * 11
14443 = 101 * 11 * 13
16665 = 101 * 11 * 3 * 5
abcd(5555, 7777, 9999, 12221, 14443, 16665) = 101 * 11 = 1111

total number of cats = 12
total number of dogs = 11
total number of rabbits = 6
then total number of hamsters = total pets - total cats, dogs, and rabbits
total number of hamsters = 33 - ( 12 + 11 + 6)
total number of hamsters = 4

Step-by-step explanation:
The tangent identity is ...
tan = sin/cos
SubstitutionSubstituting the given values of sine and cosine, we have ...
[tex]\tan{x}=\dfrac{\sin{x}}{\cos{x}}=\dfrac{\dfrac{42}{55}}{\dfrac{14\sqrt{6}}{55}}[/tex]
SimplificationAt this point, it becomes a problem in simplifying a compound fraction. This can be done by dividing the fractions in the usual way, and cancelling common factors from numerator and denominator.
We note the denominators (55) are the same, and that 42=3·14, so we can simplify this to ...
[tex]\tan{x}=\dfrac{3}{\sqrt{6}}=\dfrac{3\cdot\sqrt{6}}{\sqrt{6}\cdot\sqrt{6}}=\dfrac{3\sqrt{6}}{6}\\\\\boxed{\tan{x}=\dfrac{\sqrt{6}}{2}}[/tex]
The step of multiplying by (√6)/(√6) is for the purpose of "rationalizing the denominator," making the denominator a rational number: (√6)² = 6.

If you roll orange you win a donut, if you roll green you get eaten by Maggie. What is the probability that you will roll anything but orange
The probability that person will be eaten by Maggie is 16.67%.
Given there are 6 sided coloured dice. Colours are red, blue,green,purple, indigo and orange.
We have to find the probability that the person will be eaten by Maggie.
Probability is the likeliness of happening an event among all the possible events. It lies between 0 and 1. The probability is the numberof items divided by the total number of items.
Number of green coloured sides=1
Total number of sides=6
Probability of getting green when the dice is rolled 1 time=1/6=0.1667
We have been told that if green comes then person will be eaten by Maggie so the probability that the person will be eaten by Maggie is 0.1667 which is 16.67%.
