The type of triangle formed from the side lengths of a triangle 2, 10, 11 is a scalene triangle.

Based on the given side lengths of a triangle (2, 10, 11), we can determine the type of triangle formed by examining their relationships. First, let's check if these side lengths can form a valid triangle using the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides must be greater than the length of the remaining side. In this case, 2 + 10 > 11, 2 + 11 > 10, and 10 + 11 > 2, so a triangle can be formed.

Now let's identify the type of triangle. There are three main categories to consider: equilateral, isosceles, and scalene. An equilateral triangle has all three sides equal in length, which doesn't apply here. An isosceles triangle has two sides with equal lengths, but in this case, all three sides have distinct lengths. Therefore, the triangle is a scalene triangle, meaning it has no sides of equal length.

In summary, the triangle formed by side lengths 2, 10, and 11 is a scalene triangle because all three sides have different lengths and satisfy the Triangle Inequality Theorem.

When researchers record how much of an experimental medication is in a person's bloodstream every hour, they are measuring the medication's concentration over time. This information is important because it can help determine the medication's effectiveness and potential side effects.

The half-life of a medication is the time it takes for half of the drug to be eliminated from the body. In this case, the half-life of the experimental medication is about 6 hours.

Knowing the half-life of a medication is important because it can help predict how long it will take for the drug to be eliminated from the body and when the next dose should be administered. For example, if a medication has a half-life of 6 hours, it means that after 6 hours, half of the medication will be eliminated from the body.

After another 6 hours, half of the remaining medication will be eliminated, and so on.
By monitoring the concentration of the medication in a person's bloodstream every hour, researchers can determine how quickly the drug is being absorbed and eliminated from the body. z

x^(1/2) = 0

This equation has no real solutions, since no real number raised to any power can equal 0.

Therefore, the sum of all values of x satisfying r*(x) = 0 or P(x) is undefined is just 2, the only value of x for which r*(x) - 0.

To find the values of x for which r*(x) - 0 or P(x) is undefined, we first need to determine what r*(x) and P(x) are.

r*(x) is the derivative of f(x), which we can find using the product rule:

r*(x) = (1/2)x^(-1/2)(x-4) + x^1/2(1)

Simplifying this expression, we get:

r*(x) = (x-2)/sqrt(x)

To find the values of x for which r*(x) - 0, we can set r*(x) equal to 0 and solve for x:

(x-2)/sqrt(x) = 0

x - 2 = 0

x = 2

So the only value of x for which r*(x) - 0 is x = 2.

Next, we need to find the values of x for which P(x) is undefined. P(x) is undefined when the denominator of the expression for f(x) is equal to 0, since division by 0 is undefined. The denominator of f(x) is x^(1/2), so we need to solve the equation x^(1/2) = 0:

x^(1/2) = 0

This equation has no real solutions, since no real number raised to any power can equal 0.

Therefore, the sum of all values of x satisfying r*(x) = 0 or P(x) is undefined is just 2, the only value of x for which r*(x) - 0.

The function given is y = 18000(0.76)^t, where y represents the value of the car and t represents the time in years.

This is an exponential decay function, meaning that the value of the car decreases over time. To determine if the value of the function will ever be 0, we would need to find if there exists a time t when y = 0. Let's analyze the function:

0 = 18000(0.76)^t

In an exponential decay function, the base (0.76 in this case) is between 0 and 1, so as time (t) increases, (0.76)^t will approach 0, but it will never actually reach 0. Thus, the value of the car will keep decreasing over time but will never be exactly 0.

In summary, the value of the function, which represents the car's value, will never be 0, but it will get infinitely close to 0 as time progresses. This is a characteristic of exponential decay functions, where the value never reaches 0 but approaches it as time goes on.

The absolute maximum value of the function on the interval (-5, 11) is 670, which occurs at x = -5, and the absolute minimum value is approximately 400.847, which occurs at x ≈ 1.154.

To find the absolute maximum and minimum values of the function f(x) = -2x^3 + 8x + 400 on the interval (-5, 11), we need to consider the critical points and the endpoints of the interval.

First, we find the derivative of the function:

f'(x) = -6x^2 + 8

Setting f'(x) = 0 to find the critical points, we get:

-6x^2 + 8 = 0

x^2 = 4/3

x = ±√(4/3)

Since only √(4/3) is within the interval (-5, 11), this is the only critical point we need to consider.

Next, we evaluate the function at the endpoints of the interval:

f(-5) = -2(-5)^3 + 8(-5) + 400 = 670

f(11) = -2(11)^3 + 8(11) + 400 = -1666

Finally, we evaluate the function at the critical point:

f(√(4/3)) = -2(√(4/3))^3 + 8(√(4/3)) + 400 ≈ 400.847

Therefore, the absolute maximum value of the function on the interval (-5, 11) is 670, which occurs at x = -5, and the absolute minimum value is approximately 400.847, which occurs at x ≈ 1.154.

To find the derivative of the function y = 2(2^x)-2, we will use the power rule and the chain rule of differentiation.

Apply the power rule to the function y = 2(2^x)-2. The power rule states that if f(x) = x^n, then f'(x) = nx^(n-1).

y' = [2(2^x)-2]'

Answer:

The answer to your problem is, F = 15N

Step-by-step explanation:

You have: F = ka

Where F is the force acting on the object, A is the object's acceleration and is the constant of proportionality.

Which will be our letters that we will NEED to use for today.

You can calculate the constant of proportionality by substituting F = 18 and a = 6 into the equation and solving for k: Then we can now figure out the “ formula of expression “

18 = k6

k = [tex]\frac{18}{6}[/tex]

K = 3

We would need to calculate the force when the acceleration of the object becomes 5 m/s², as following: F = 3 x 5 ( Basic math )

Thus the answer to your problem is, F = 15N

Points lie on the graph of the inverse of f(x)=5x−2.

Hence, the correct option is C,E,F.

To find the points on the graph of the inverse of f(x), we need to switch the x and y coordinates of each point on the graph of f(x). Then, we can simplify the equation to isolate y and get the inverse function.

f(x) = 5x - 2

y = 5x - 2 (replace f(x) with y)

x = 5y - 2 (switch x and y)

x + 2 = 5y (add 2 to both sides)

y = (x + 2)/5 (divide both sides by 5)

So, the inverse function of f(x) is

[tex]f^{-1}[/tex](x) = (x + 2)/5

Now, we can substitute each point from the given options into the inverse function to see if it lies on the graph of the inverse of f(x).

1. (0, -2)

[tex]f^{-1}[/tex](0) = (0 + 2)/5 = 2/5

No, this point does not lie on the graph of the inverse of f(x).

3. (-2, 0)

[tex]f^{-1}[/tex](-2) = (-2 + 2)/5 = 0

Yes, this point lies on the graph of the inverse of f(x).

4. (2/5, 1)

[tex]f^{-1}[/tex](2/5) = (2/5 + 2)/5 = 6/25

No, this point does not lie on the graph of the inverse of f(x).
