Answer:

D) \(1 < x\leq 4\)

Step-by-step explanation:

1 is not included, but 4 is included, so we can say \(1 < x\leq 4\)

Explanation

To solve the question, we will be aware that

There are 3 hours between 6PM and 9PM ,

The main pump's emptying rate is 1/4 tanker per hour. It will be open

the entire 3 hours, so it will empty 3/4 of the tank.

this means that the auxiliary pump must empty the remaining 1/4

Thus

Thus, we will have

Therefore

The auxiliary pump should start by 6pm + 45 minutes = 6:45pm

The point on the line y = -2x + 2 closest to (3,10) is (1.3, -0.6).

To find the point on the line y = -2x + 2 closest to (3,10), we can use the formula for the distance between a point (x1, y1) and a line ax + by + c = 0:

distance = |ax1 + by1 + c| / sqrt(a^2 + b^2)

In this case, the line is y = -2x + 2, so we can rewrite it as 2x + y - 2 = 0. Therefore, a = 2, b = 1, and c = -2. The point we want to find the distance to is (3,10), so x1 = 3 and y1 = 10. Substituting these values into the distance formula, we get:

distance = |2(3) + 1(10) - 2| / sqrt(2^2 + 1^2)

= 11 / sqrt(5)

So the function giving the distance between the point and the line is:

s(x) = 11 / sqrt(5)

To find the point on the line y = -2x + 2 closest to (3,10), we need to find the intersection of the line and the perpendicular line passing through (3,10). Since the slope of y = -2x + 2 is -2, the slope of the perpendicular line is 1/2 (negative reciprocal). This line passes through (3,10), so we can write its equation in point-slope form:

y - 10 = (1/2)(x - 3)

y = (1/2)x + 8.5

Now we need to solve the system of equations consisting of y = -2x + 2 and y = (1/2)x + 8.5. Substituting y = (1/2)x + 8.5 into the first equation, we get:

(1/2)x + 8.5 = -2x + 2

Solving for x, we get x = 1.3. Substituting this value into either equation gives us y = -0.6. Therefore, the point on the line y = -2x + 2 closest to (3,10) is (1.3, -0.6).

This resulting cross product is a vector that is normal to the plane formed by the two original vectors.

Substitute the given values for each parameter in the formula, and then simplify and solve for vxv.

This gives :vxv = [1 * 5 - 3 * 2, 3 * 2 - 1 * 5, 0 * (-4) - 1 * 3] ;

vxv = [23, 9, -3], the answer is :

vxv = [23, 9, -3].

The formula is given below :

vxv = [v1(y) * v2(z) - v1(z) * v2(y), v1(z) * v2(x) - v1(x) * v2(z), v1(x) * v 2(y) - v1(y) * v2(x)];

Given:v1 = [0, 1, 2]; v2 = [3, -4, 5];

solution x = 1; y = 2;

z = 3;

vxv = [v1(y) * v2(z) - v1(z) * v2(y), v1(z) * v2(x) - v1(x) * v2(z), v1(x) * v2(y) - v1(y) * v2(x)];

Answer: vxv = [23, 9, -3]

The given terms are:v1 = [0, 1, 2]; v2 = [3, -4, 5];

solution x = 1; y = 2; z = 3;

The cross product or vector product is defined as a binary operation on two vectors in a three-dimensional space.

The resulting cross product, as opposed to the scalar dot product, is a vector perpendicular to both original vectors.

Let's use the formula to calculate the cross product for the vectors

v1 and v2.

When the cross product is performed on two vectors, a third vector is produced that is perpendicular to both original vectors.

Hypothesis testing is an important statistical tool that helps us make informed decisions based on data and evidence.

The hypothesis statement h: µ = 25 is an example of a null hypothesis. A null hypothesis is a statement that suggests there is no significant difference between two variables or that any difference is due to chance. It is often denoted as H0 and is used to compare against an alternative hypothesis, which suggests that there is a significant difference between two variables. In this case, the null hypothesis is that the population mean µ is equal to 25, and there is no significant difference between the sample mean and the population mean. If the null hypothesis is rejected, it means that there is enough evidence to suggest that the alternative hypothesis is true. However, if the null hypothesis cannot be rejected, it does not necessarily mean that it is true. It only suggests that there is not enough evidence to support the alternative hypothesis.

If the omnibus null hypothesis is rejected in a one-factor ANOVA, then, we can conclude that at least one of the population means is different from at least one other population mean.

ANOVA table gives us the total sum of squares ( TSS ), the residual sum of squares ( RSS ) and the estimated sum of squares ( ESS ).

It establishes the relation that:

ESS + RSS = TSS.

If we reject the omnibus null hypothesis, then it means that:

at least one of the population means is different from at least one other population mean.

Therefore, we get that, if the omnibus null hypothesis is rejected in a one-factor ANOVA, then, we can conclude that at least one of the population means is different from at least one other population mean.

Answer:

World War II started on September 1st, 1939, a decade after America’s stock market crash and downfall of the economy, which was in 1929, when Germany, led by a man born in Austria called Adolf Hitler, invaded Poland. France and England immediately declared war on Germany and Germany’s allies.

Germany had two allies, Japan and Italy, Italy mostly provided food and supplies, while Japan provided manpower, along with Germany. Germany, Japan, and Italy were called the Axis powers, and England, Russia (Then called the Soviet Union), and America (When America joined the war), along with many other countries, such as China and France (Except for the four years which Germany occupied France, 1940--1944), were called the Allied powers.

Germany invaded and occupied Austria, Belgium, France, Norway, Luxembourg, Greece, Czechoslovakia, Greece, Denmark, Holland, Hungary, the Netherlands, and many other countries with the help of Italy and Japan.

The United States wanted to be neutral through World War II like the Irish and Swiss, but the Axis Powers did not let this happen. Instead, Japan bombed Pearl Harbor and utterly destroyed and sunk many ships, so the United States had no choice but to join the war and the Allied forces.

The United States both lost and won many battles, and Germany was losing battles against the Soviet Union and England. Germany lost many battles in the Soviet Union, which was fought in harsh and bitter cold, and also lost the Battle of Britain fought in the skies over England between Britain’s Royal Air Force (RAF) and Germany’s Luftwaffe.

Many people died as a result of the Battle of Britain by bombs and flying shrapnel. In order to try to get their country back to normal, Great Britain started to ration food, drafted men over eighteen to go to the war front, made shelters all over England, in cities, towns, even in the country, in case of an air raid. The Battle of Britain was mostly fought in the skies of London, but enemy planes heading towards London to fight might drop a bomb to wipe away towns, cities, or a part of country off the map.

Germany soon retreated from Great Britain and thought that England would surrender with the rest when Germany conquered and ruled the world, which was Germany’s goal, but England, after some recovery, fought Germany as hard as ever, angered by the people and planes lost because of the Battle of Britain.

In the middle of this, President Franklin Delano Roosevelt died because of a mixture of bad health, too much stress, and his polio. Americans grieved for President Roosevelt, and elected a new president, President Harry Truman.

With forces fighting with both the Soviet Union and England, and later fighting on D-Day, Germany could not last for long, even with its two allies. But the number of allies Germany had soon reduced to one, for Italy joined the Allied powers, betraying the Axis Powers. Germany  desperately tried to fight back the forces of the Allied powers, but soon surrendered days after Adolf Hitler’s death, on May 8th, 1945.

Even when its ally Germany had surrendered and Italy had gone over to the Allies, Japan still fought, even though there was very little chance they would win. This was a bad idea, an idea which would change history. The Allied powers turned their full attention on defeating Japan, which was a bad thing, since Japan could only take over a few islands in the Pacific belonging to the United States and could not defeat any others in the beginning when the Allied powers’ attention was divided. As a result, many, at least hundreds, died, deaths that were not even necessary. The United States dropped two atomic bombs from one of America’s bomber planes on Japan’s two major cities, Hiroshima and Nagasaki days apart, so Japan surrendered, unable to lose any more people then it had already.

The two atomic bombs were built in the midst of fighting and stress of World War II in Manhattan, New York by a group of people who specialized in physics, math, and chemistry. The atomic bomb’s code name was: The Manhattan Project. The Manhattan Project, when done and ready, after dropped from an American bomber plane, killed over a hundred thousand Japanese in the two major cities Hiroshima and Nagasaki, most of them regular Japanese civilians going about their daily life.

World War II was a very important war and time period that changed the world. It changed the human race. The atomic bomb, invented in World War II, soon led other countries, such as England, France, the Soviet Union (Later known as Russia), and China to build it too, which gave these countries a huge advantage in war. America’s stock market bounced back. President Harry Truman became popular for ending World War II.

We integrate the remaining integral: ∫(5x - (1/2)x^2) dx = (5/2)x^2 - (1/6)x^3 + C The final result is: ∫x(5 - x) dx = x(5x - (1/2)x^2) - ((5/2)x^2 - (1/6)x^3) + C

To integrate x^5 - x dx by parts, we need to choose u and dv. Let's choose u = x^5 and dv = (5 - x) dx. Then du/dx = 5x^4 and v = ∫(5 - x) dx = 5x - (1/2)x^2 + C.

Now, using the formula for integration by parts, we have:

∫x^5 - x dx = u*v - ∫v*du/dx dx
= x^5(5x - (1/2)x^2) - ∫(5x - (1/2)x^2)*5x^4 dx
= 5x^6 - (1/2)x^7 - (5/6)x^6 + (1/20)x^5 + C
= (9/20)x^5 - (7/6)x^6 + 5x^6 + C

Therefore, the antiderivative of x^5 - x dx using integration by parts with dv = 5 - x dx is (9/20)x^5 - (7/6)x^6 + 5x^6 + C.

To consider the following integral: ∫x(5 - x) dx, we will integrate by parts, letting dv = (5 - x) dx.

To integrate by parts, we use the formula ∫u dv = uv - ∫v du. In this case, we have:

u = x, so du = dx
dv = (5 - x) dx, so v = ∫(5 - x) dx = 5x - (1/2)x^2

Now, we can plug these values into the formula:

∫x(5 - x) dx = x(5x - (1/2)x^2) - ∫(5x - (1/2)x^2) dx

To finish, we integrate the remaining integral:

∫(5x - (1/2)x^2) dx = (5/2)x^2 - (1/6)x^3 + C

So, the final result is:

∫x(5 - x) dx = x(5x - (1/2)x^2) - ((5/2)x^2 - (1/6)x^3) + C

Answer:

b = 93° , c = 87°

Step-by-step explanation:

b and 93° are vertically opposite angles and are congruent , then

b = 93°

c and 93° are a linear pair and sum to 180° , that is

c + 93° = 180° ( subtract 93° from both sides )

c = 87°

Answer:

b=93

c=87

Step-by-step explanation:

1. For b, the angle is 93 degrees because of the vertical angle theorem, where two straight lines intersect, forming two sets of linear pairs with congruent angles.

Therefore, that angle is 90 degrees.

2. For c, use the given angle that is provided, since angle C and the given angle are supplementary (equaling 180 degrees), we can subtract the total (180) from the part (93)
