The formula to find the unit vector of a given vector.

\(v = a i + b j + c k\)

is given by,

\(\[\hat{v} = \frac{v}{|v|} = \frac{a\text{i} + b\text{j} + c\text{k}} {\sqrt {a^2 + b^2 + c^2}}\]\)

Now, we need to find the unit vector having the same direction as

\(v = 8i − 6j.\)

ERTŪI let's calculate the magnitude of v and substitute the values in the formula mentioned above.

Then we can get the unit vector which is of same direction as v.

Let's calculate the magnitude of the given vector v.

\(|v| = √ (a² + b² + c²) = √ (8² + (-6) ² + 0²) = √100 = 10\)

As we have calculated the magnitude of v,

now we can calculate the unit vector of the given vector.

To determine if the linear system corresponding to an augmented matrix [a1 a2 a3 b] has a solution, we can check whether the vector b is in the span of the vectors {a1, a2, a3}.

In linear algebra, the augmented matrix represents a system of linear equations. The columns a1, a2, and a3 correspond to the coefficients of the variables in the system, while the column b represents the constants on the right-hand side of the equations. To check if the system has a solution, we need to determine if the vector b is a linear combination of the vectors a1, a2, and a3.

If the vector b lies in the span of the vectors {a1, a2, a3}, it means that b can be expressed as a linear combination of a1, a2, and a3. In other words, there exist scalars (coefficients) that can be multiplied with a1, a2, and a3 to obtain the vector b. This indicates that there is a solution to the linear system.

On the other hand, if b is not in the span of {a1, a2, a3}, it implies that there is no linear combination of a1, a2, and a3 that can yield the vector b. In this case, the linear system does not have a solution.

Therefore, determining whether the vector b is in the span of {a1, a2, a3} allows us to determine if the linear system corresponding to the augmented matrix [a1 a2 a3 b] has a solution or not.

The number of push-ups did sara did during gym class if for every 7 push-ups Dulce can do, Sara can do 6 is 24 push ups.

Number of push ups Dulce can do : number of push ups Sara can do

Let

number of push ups Sara does = x

7 : 6 = 28 : x

7/6 = 28/x

cross product

7 × x = 28 × 6

The answer of the given question based on perimeter of trapezoid the ratio will be  x:y is 8:5.

A trapezoid is quadrilateral with at least one pair of the parallel sides. The parallel sides are called  bases of  trapezoid, and  non-parallel sides are called legs.

Let's denote the lengths of the four sides of Trapezoid 1 as a, b, c, and d, and the lengths of the corresponding sides of Trapezoid 2 as m, n, p, and q, respectively. Then we have:

a + b + c + d = 240 (perimeter of Trapezoid 1)

m + n + p + q = 150 (perimeter of Trapezoid 2)

Since Trapezoid 1 and Trapezoid 2 are similar, we can write:

m = ax

n = bx

p = cy

q = dy

where x and y are the ratios of the longer and shorter bases of Trapezoid 1 to Trapezoid 2, respectively.

Substituting these expressions into the equations for the perimeters of the trapezoids, we get:

a(x+y) + b(x+y) + c(x+y) + d(x+y) = 240

(ax+bx+cy+dy) = 150

Simplifying these equations, we get:

(a+b+c+d)(x+y) = 240

(a+b+c+d)(x+y)(x/y) = 150

by Dividing  second equation by  first, we will get:

x/y = 240/150 = 8/5

Therefore, the ratio x:y is 8:5.

Step-by-step explanation:

Given that \(\(T(n)\) = \(10n^2-3n\)\) if (\(\(n=1\)\)), you have to prove it by induction. So, we have proved it by induction that  \($$\(T(n)=10n^2-3n\)$$\)  if ( n= 1). The given statement is true for all positive integers n

Let's do it below: The base case (n=1) is given as follows: \(T(1)\) =\(10\cdot 1^2-3\cdot 1\\&\)=\(7\end{aligned}$$\). This implies that \(\(T(1)\)\) holds true for the base case.

Now, let's assume that \(\(T(k)=10k^2-3k\)\) holds true for some arbitrary \(\(k\geq 1\).\)

Thus, for n=k+1, T(k+1) = \(10(k+1)^2-3(k+1)\\&\) = \(10(k^2+2k+1)-3k-3\\&\)=\(10k^2+20k+7k+7\\&\) = \(10k^2-3k+20k+7k+7\\&\) = \(T(k)+23k+7\\&\) = \((10k^2-3k)+23k+7\\&\) =  \(10(k+1)^2-3(k+1)\).

Therefore, we have proved that the statement holds true for n=k+1 as well. Hence, we have proved it by induction that  \($$\(T(n)=10n^2-3n\)$$\)  if (n=1). Therefore, the given statement is true for all positive integers n.

To determine whether the engineer's claim that the method is unbiased is false, we need to perform a hypothesis test.

The null hypothesis, denoted as H0, assumes that the method is unbiased, meaning that the mean error is zero. The alternative hypothesis, denoted as Ha, assumes that the method is biased, and the mean error is not zero.

Given a sample of 18 measurements with a mean error of 457.7 kNm and a standard deviation of 317.7 kNm, we can calculate the test statistic using a t-test. The test statistic is calculated by dividing the sample mean by the standard deviation divided by the square root of the sample size.

If the calculated test statistic falls within the rejection region defined by a chosen significance level, typically denoted as α, we can reject the null hypothesis and conclude that the engineer's claim of unbiasedness is false. The significance level determines the probability of making a Type I error, which is the probability of rejecting a true null hypothesis.

To make a definitive conclusion, we would compare the calculated test statistic to the critical value(s) from the t-distribution table or use statistical software to calculate the p-value associated with the test statistic. If the p-value is less than the significance level, we reject the null hypothesis and conclude that the claim of unbiasedness is false. Conversely, if the p-value is greater than the significance level, we fail to reject the null hypothesis and cannot conclude that the claim is false.
