Solve the matrix equation X-A=B for X if A= [8, -2, -3, 9, -1, 5] and B= [0, 7, 2 -3, -7, -1]
djverab [1.8K]

If <em>X</em> - <em>A</em> = <em>B</em>, then <em>X</em> = <em>A</em> + <em>B</em>. So

X = \begin{bmatrix}8&-2\\-3&9\\-1&5\end{bmatrix} + \begin{bmatrix}0&7\\2&-3\\-7&-1\end{bmatrix} \\\\ X = \begin{bmatrix}8+0&-2+7\\-3+2&9-3\\-1-7&5-1\end{bmatrix} \\\\ X = \begin{bmatrix}8&5\\-1&6\\-8&4\end{bmatrix}

A new airport is in its planning phase. One particular challenge is that there are several tall buildings in the vicinity. In pa
mixer [17]

Answer:

<em>Could an airplane take off and clear this tall building?  YES</em>

Step-by-step explanation:

<u>Trigonometry</u>

The building and the ground form a right (90°) angle. The path of the airplane (assumed a straight line) completes the right triangle.

The takeoff angle of the plane θ=15° has the height of the building (450 feet) as the opposite side and the horizontal distance from the end of the runway (2500 feet) as the adjacent side.

The tangent of θ is defined as the following ratio:

\displaystyle \tan\theta=\frac{\text{opposite leg}}{\text{adjacent leg}}

\displaystyle \tan \theta=\frac{450}{2500}

\displaystyle \tan \theta=0.18

Calculating the inverse tangent function:

\theta=\arctan 0.18

\theta\approx 10^\circ

This means the angle needed to clear the tall building is about 10° and it's within the maximum airplane's takeoff angle.

Could an airplane take off and clear this tall building?  YES

in a farm there are 600 mango trees. the number of trees in each row is 10 less than twice the number of rows. does each row hav
iren [92.7K]

The area of the farm is the number of trees on it.

Each row of the farm does not have 50 trees

Let

<em />x \to<em> number of rows</em>

<em />y \to<em> number of trees in each row</em>

<em />

So, we have:

<em />y = 2x - 10<em> --- twice less than the number of rows</em>

The area of the farm is:

Area = x \times y

Where

Area = 600 --- the number of trees

So, we have:

x \times y = 600

Substitute y = 2x - 10

x \times (2x - 10) = 600

Substitute 50 for x

50 \times (2 \times 50 - 10) = 600

50 \times (100 - 10) = 600

50 \times 90 = 600

4500 = 600

The above equation is not true.

This means that, each row does not have 50 trees
