f(x)=a⁵+cos⁵x, find f′(x)
Answers
We need to find the derivative of the function f(x) = \(a^5\) + \(cos^5\)(x). The derivative of f(x) is f'(x) = 5\(a^4\) - 5\(cos^4\)(x) * sin(x). We can use the power rule and chain rule.
To find the derivative of f(x), we use the power rule and the chain rule. The power rule states that if we have a function g(x) =\(x^n\), then the derivative of g(x) with respect to x is given by g'(x) = n*\(x^(n-1)\).
Applying the power rule to the term \(a^5\), we have:
(\(a^5\))' = 5\(a^(5-1)\) = 5\(a^4\)
To differentiate the term \(cos^5\)(x), we use the chain rule. Let u = cos(x), so the derivative is:
(\(cos^5\)(x))' = 5(\(u^5\)-1) * (u')
Differentiating u = cos(x), we get:
u' = -sin(x)
Substituting these derivatives back into the expression for f'(x), we have:
f'(x) = 5\(a^4\)+ 5\(cos^4\)(x) * (-sin(x))
Simplifying further, we have:
f'(x) = 5\(a^4\) - 5\(cos^4\)(x) * sin(x)
Therefore, the derivative of f(x) is f'(x) = 5\(a^4\) - 5\(cos^4\)(x) * sin(x).

b. I only. The equation cosh(x) + sinn(x) = 1 is a trigonometric equation involving hyperbolic functions. Since statement I is incorrect and statement II is correct, the correct option is b. I only.
It does not hold true for all values of x and n. Therefore, statement I is not correct.
On the other hand, the equation sinh(x) cosh(y) = sinh(x + y) + sinh(x - y) is an identity involving hyperbolic functions. It holds true for all values of x and y. Therefore, statement II is correct.
Since statement I is incorrect and statement II is correct, the correct option is b. I only.

please help me answer this question-
Answers
Answer:
\( \displaystyle GH = 2 \sqrt{30} \)
\( \displaystyle FH = 2 \sqrt{10} \)
\( \displaystyle m \angle G = {30}^{ \circ} \)
Step-by-step explanation:
QUESTION-2:we are given a right angle triangle
it's a 30-60-90 triangle of which FH is the shortest side
remember that,in case of 30-60-90 triangle the the longest side is twice as much as the shortest side thus
our equation is
\( \displaystyle 2FH=4\sqrt{10}\)
divide both sides by 2
\( \displaystyle\frac{2FH}{2}= \frac{ 4 \sqrt{10} }{2}\)
\( \displaystyle FH =2 \sqrt{10}\)
Question-1:in order to figure out GH we can use Trigonometry because the given triangle is a right angle triangle
as we want to figure out GH we'll use sin function
remember that,
\( \displaystyle \sin( \theta) = \frac{opp}{hypo} \)
let our opp, hypo and \(\theta\) be GH, 4√10 and 60° respectively
thus substitute:
\( \displaystyle \sin( {60}^{ \circ} ) = \frac{GH}{4 \sqrt{10} } \)
recall unit circle:
\( \displaystyle \frac{ \sqrt{3} }{2} = \frac{GH}{4 \sqrt{10} } \)
cross multiplication:
\( \displaystyle 2 GH = 4 \sqrt{10} \times \sqrt{3} \)
simplify multiplication:
\( \displaystyle 2 GH = 4 \sqrt{30} \)
divide both sides by 2:
\( \displaystyle GH = 2 \sqrt{30} \)
QUESTION-3:Recall that, the sum of the interior angles of a triangle is 180°
therefore,
\( \displaystyle m \angle G + {60}^{ \circ} + {90}^{ \circ} = {180}^{ \circ} \)
simplify addition:
\( \displaystyle m \angle G + {150}^{ \circ} = {180}^{ \circ} \)
cancel 150° from both sides
\( \displaystyle m \angle G = {30}^{ \circ} \)
Two sides of a triangle are 8 inches and
10 inches in length and the angle θ between
them is increasing at a rate of 1/10 radians
per second.
Find the rate at which the area of the tri-
angle is increasing when θ = π/3.
Answers
When the angle θ of a triangle, with sides measuring 8 inches and 10 inches, is increasing at a rate of 1/10 radians per second, the rate at which the area of the triangle is increasing when θ = π/3 is approximately 6.43 square inches per second.
To find the rate at which the area of the triangle is increasing, we can use the formula for the rate of change of the area with respect to time:
dA/dt = (1/2) * a * b * dθ/dt * sin(θ),
where A is the area of the triangle, a and b are the lengths of the sides, θ is the angle between the sides, and dθ/dt is the rate of change of θ with respect to time.
In this case, a = 8 inches, b = 10 inches, and dθ/dt = 1/10 radians per second. We are interested in finding the rate of change of the area when θ = π/3.
Plugging in these values into the formula, we have:
dA/dt = (1/2) * 8 * 10 * (1/10) * sin(π/3).
Simplifying the expression, we get:
dA/dt = 4 * sin(π/3) = 4 * (√3/2) = 2√3.
Therefore, when θ = π/3, the rate at which the area of the triangle is increasing is approximately 2√3 square inches per second. Evaluating this expression, we find that the rate is approximately 6.43 square inches per second.

how to tell if a variable is discrete or continuous
Answers
To determine whether a variable is discrete or continuous, you need to consider the nature and characteristics of the variable.
Here are some guidelines to help you make the distinction:
1. Discrete Variables:
- Discrete variables have a countable or finite number of possible values.
- The values of a discrete variable are often whole numbers or integers.
- Examples of discrete variables include the number of children in a family, the number of cars in a parking lot, or the number of customers in a store at a given time.
2. Continuous Variables:
- Continuous variables can take on any value within a certain range or interval.
- The values of a continuous variable can be infinitely divisible and can include decimal fractions.
- Examples of continuous variables include height, weight, time, temperature, or the amount of rainfall.
However, it's worth noting that some variables may fall in a gray area and can be considered both discrete and continuous depending on the context.
For example, age can be treated as a discrete variable when only whole numbers are considered (e.g., number of years), but it can be treated as continuous when fractional values (e.g., age in years and months) are considered.
When determining if a variable is discrete or continuous, it's important to consider the level of measurement and the nature of the values being observed. Discrete variables typically involve counts or distinct categories, while continuous variables involve measurements along a continuum.

What percentage of the shape is pink?
Write your answer using a percent sign (%).

It is 20% because there is 5 squares. So we need to make this a fraction. So the fraction would be 1/5. So we then have to find a multiple for 1/5 because it is out of 100. So 20x5=100. So we have to multiply the top and the bottom part of the fraction by 20. So 5x20=100 and 1x20=100. So then we get 20/100. So the top number is your percent. So 20% is your answer. Good luck.
