The magnitude of 2(u-v +w) is √292.

The given vectors are u = 2i + 3j, v=-i, and w = 5i – 6j.

We need to find the value of 2(u-v+w).

The formula to determine the magnitude of a vector (in two-dimensional space) v = (x, y) is: |v| =√(x²+ y²). This formula is derived from the Pythagorean theorem.

Now, 2(2i + 3j-(-i)+5i-6j)

=2(2i+3j+i+5i-6j)

=2(8i-3j)=16i-6j

The magnitude of 16i-6j=√16²+6²=√256+36=√292

Therefore, the magnitude of 2(u-v +w) is √292.

E) A hypothesis test with a null hypothesis that the dropout rate is less than or equal to the highest dropout rate

Step-by-step explanation:

The hypothesis test is the type of test that helped a scientist to determine the relationship between two variables-one constant independent variable and an dependent variable. For the dropout rates in the different schools, it would be better to use the hypothesis test for the evaluation.

Step-by-step explanation:

Step 1: Define

y = sinx

x = 2π

Step 2: Find Derivative

This is the function of the tangent line for y.

Step 3: Find slope

This tells us that the slope of the tangent line is 1 at x = 2π.

Step 4: Write equation

Find a point.

Write tangent function.

This is the equation of the tangent line at x = 2π.

Answer:

The answer is 36m.

Step-by-step explanation:

So, first of all, you need to remember that the formula for the area of a square is x^2, or one side multiplied by another side. Also recall that in a square all sides are equal. This means that x^2=81. Now, the square root of 81 equals 9 (you should have this memorized by now). So, if each side of the square is 9, and  there are 4 sides, the perimeter would be 9*4, which is 36m.

Assuming the triangle adds up to 180°, x = 55 because 55 + 5 = 60. 60 x 3 = 180

∠A ≅ ∠Z

you can determine this by seeing that both angles have two curved lines, therefor showing they have the same measurement.

∠B ≅ ∠Y

you can also determine this by seeing that they both have one curved line showing that they share the same measurement.

∠C ≅ ∠X

once again, you can determine this by seeing that both angles are marked with three curved lines, meaning they share the same measurements.

line AB ≅ line ZY

just like before, you can determine that they are equivalent to each other by seeing that both lines have three dashes showing that they have the same measurement.

line AC ≅ line ZX

you can determine these lines are equivalent because they both have one dash showing they are the same length as each other.

line BC ≅ line YX

once again, both lines have two dashes, showing that they are equivalent in length.

ΔCAB ≅ XZY

you can determine this by seeing that all three angles and all three sides on both triangles share measurements with the other triangle

Q.E.D.

Answer:

2,460 liters per hour

Step-by-Step Explanation:

The problem above requires only two operations: multiplication and addition. First, you have to answer this question: How much is 2.5% of 2,400 liters?"

You may do this by multiplying 2,400 by 2.5%.

2,400 x 2.5% (0.025) = 60 liters (this is the amount that the new model can fill more than old model).

Then, you have to add 60 liters to 2,400 liters.

2,400 liters + 60 liters = 2,460 liters

This means that the new model can fill 2,460 liters per hour.

Answer: The required three consecutive odd integers are 7, 9 , 11.

Step-by-step explanation:

Let x , x+2 , x+4 be the three consecutive odd integers.

As per given ,  

10(x) = 59+x+4

⇒10x= 59+x+4

⇒ 9x= 63

⇒ x= 7   [ divide both sides by 7]

Hence, the required three consecutive odd integers are 7, 9 , 11.

Step-by-step explanation:

The given number is 7700.

We need to find the relationship between the values of the digit 7s in it.

The digit in the extreme left is 7 and second no is again 7.

The place value of first 7 is 7000

The place value of second 7 is 700.

Taking ratio of place value of 7 in first 7 and for second 7 as follows :

[tex]R=\dfrac{7000}{700}\\\\R=10[/tex]

So, value of first 7 is 10 times that of the value of second 7.
