BY Pythagorus theorem :-

=》

$55 {}^{2} = 33 {}^{2} + b {}^{2}$

=》

$3025 = b {}^{2} + 1089$

=》

$b {}^{2} = 3025 - 1089$

=》

$b {}^{2} = 1936$

=》

$b = \sqrt{1936}$

Find all constants a such that the vectors (a, 4) and (2, 5) are parallel.

Nezavi [6.7K]

Answer:

$\displaystyle a = \frac{8}{5}$ .

Step-by-step explanation:

Two vectors $(x_1,\, y_1)$ and $(x_2,\, y_2)$ are parallel to one another if and only if the ratio between their corresponding components are equal:

$\displaystyle \frac{x_1}{x_2} = \frac{y_1}{y_2}$ .

Equivalently:

$\displaystyle \frac{x_1}{y_1} = \frac{x_2}{y_2}$ .

For the two vectors in this equation to be parallel to one another:

$\displaystyle \frac{a}{4} = \frac{2}{5}$ .

Solve for $a$ :

$\displaystyle a = \frac{8}{5}$ .

$\displaystyle \frac{8}{5}$ would be the only valid value of $a$ ; no other value would satisfy the $\displaystyle \frac{x_1}{y_1} = \frac{x_2}{y_2}$ equation.

A rectangle is drawn so that the width is 5 feet shorter than the length. The area of the rectangle is 14 square feet. Find the

leva [86]

Hello There!

Area = l x w
14 = $x * x - 5$
Multiples of 14:
1 and 14
7 and 2
7 and 2 are the only ones with a difference of 5.

Therefore, the length is 7ft and the width is 2ft.

Hope This Helps You!
Good Luck :)
