The required rate of change of f(x) from x = -6 to x = 3 is f'(x) = 7.
What is the rate of change?Rate of change is defined as the change in value with rest to another value is called rate of change.
Here,
Given that,
f(x) = x² + 4x -15
Now, put x = -3
f(-3) = 9 - 12 - 15
f(-3) = -18
Now put x = 6
f(6)= 36 + 24 - 15
f(6) = 45
Since we know that, the rate of change of function is given as,
f'(x) = f'(a) - f'(b) / a -b
f'(x) =f'(6) - f'(-3) / a - b
f'(x) = 45 - (-18) / 6 -(-3)
f'(x) = 63 / 9
f'(x) = 7
Thus, the required rate of change of f(x) from x = -6 to x = 3 is f'(x) = 7.

Why were jews refugees more vulnerable than German jews? What does this suggest about the society's universe of obligation at the time?
Answer:
During the Holocaust, Jews who were living in Nazi-occupied countries were more vulnerable than German Jews for several reasons. First, German Jews had some level of protection under German law until 1935, when the Nuremberg Laws stripped them of their citizenship and legal rights. In contrast, Jews in occupied countries had no legal protection or rights.
Second, German Jews had more resources and networks to help them escape persecution or go into hiding, such as family members or friends who were not Jewish or non-Jewish organizations that were sympathetic to their plight. Jews in occupied countries, especially in Eastern Europe, often had less access to resources and networks because they were living in ghettos or had been transported to concentration or extermination camps.
Third, German Jews were often better-educated and assimilated into German society, which sometimes gave them advantages in finding employment or housing. Jews in occupied countries, especially in Eastern Europe, often lived in poverty and were more likely to be living in rural areas or small towns, which made them more vulnerable to persecution and deportation.
This suggests that the society's "universe of obligation" during the Holocaust was limited to certain groups of people, namely German Jews who were seen as having more value or worth than Jews in other countries. This limited universe of obligation meant that Jews in occupied countries were not considered as valuable or worthy of protection, and therefore were more vulnerable to persecution and violence. The Holocaust serves as a tragic example of how societies can create a narrow universe of obligation that excludes entire groups of people and leads to horrific consequences.

What would have a greater effect on the volume of a cone: doubling
its radius or doubling its height? Explain?
The formula for the volume of a cone, V = (1/3)·π·r²·h, indicates that doubling the radius, quadruples the volume while doubling the height doubles the volume. Therefore;
Doubling the volume has a greater effect on the volume of a coneWhat is a circular cone?A cone is a three dimensional figure formed by lines that extend between a point and the circumference of the circular base, where the point is located on the a line perpendicular to and passing through the center of the circular base.
The formula for the volume of a cone is; V = (1/3) × π × r² × h
Where;
V = The volume of the cone
r = The radius of the cone
h = The height of the cone
Therefore;
When the radius is doubled, we get;
V₁ = (1/3) × π × (2·r)² × h = (1/3) × π × 4 × r² × h = 4 × (1/3) × π × r² × h
Therefore; V₁ = 4 × (1/3) × π × r² × h = 4·VWhen the radius of the cone is doubled, the volume of the cone increases 4 times the initial volume
When the height of the cone is doubled, we get;
V₂ = (1/3) × π × r² × 2·h = 2 × (1/3) × π × r² × h = 2·V
V₂ = 2·VWhen the height of the cone is doubled, the volume of the cone is doubled.
Therefore, doubling the radius of the cone which increases the volume to four times the initial volume has the greater effect on the volume of the cone than doubling the height which doubles the volume of the cone.

The measure of angle is less than times its complement. What is the measure of the complement of angle ?.
The measure of the complement of angle is 45 degrees.
Let's call the measure of the angle "x". The complement of the angle is defined as 90 degrees minus the measure of the angle, so the complement of the angle is 90 - x.
If the measure of the angle is less than its complement, then we can write the following inequality:
x < 90 - x
Now we can isolate x by subtracting x from both sides:
0 < 90 - 2x
And then dividing both sides by -2:
0 > -45 + x
Finally, subtracting x from both sides:
-x > -45
So, we have:
x < 45
So, the complement of the angle is 90 - x, which is greater than 90 - 45 = 45 degrees.

Answer:
Problem 1
From smallest to largest:
∠y , ∠w, ∠x
Problem 2
m∠I = 39°
Sides from shortest to longest
GH, HI, GI
Step-by-step explanation:
For question 1
The ratios of the sides of a triangle to the sine of the angle opposite them is the same
That means the ratios of the sides to each other is the same as the ratio of the sines of the angles opposite them
Since the sine of an angle increases with increasing angle value, the longest side will opposite the greatest angle measurement and the smallest length will be opposite the smallest angle measurement
So in order from smallest to largest
m∠y < m∠w < m∠x
For question 2
Since three angles of a triangle add up to 180°
Missing angle = 180 - (83 + 58)
= 180 - 141
= 39°
From shortest to longest it would be

The number of years for the speculation to reach from £785 to £1,105.58 will be 23 years.
What is compound interest?Let 'A' is the amount, 'P' is the initial amount, 'r' is the rate of interest, and 'n' is the number of years.
Then the compound interest is written as,
A = P(1 + r)ⁿ
Then the equation is given as,
£1,105.58 = £785 × (1 + 0.015)ⁿ
1.40838 = (1.015)ⁿ
n log 1.015 = log 1.40838
n = 23 years
The number of years for the speculation to reach from £785 to £1,105.58 will be 23 years.
