Answer:

97/113

Step-by-step explanation:

67 robots have legs only, 21 have wheels only, and 9 have both legs and wheels. The total number of robots with legs and/or wheels is 97.

The probability is 97/113.

If θ is an angle in standard position whose terminal side passes through (3, 4), evaluate tan(1/2)θ.

aleksandr82 [10.1K]

The tangent half angle formula, one of several, is

$\tan \dfrac a 2 = \dfrac{1 - \cos a}{\sin a}$

We have θ is opposite 4 in the 3/4/5 right triangle so

$\cos \theta = \dfrac{3}{5}$

$\sin \theta = \dfrac{4}{5}$

$\tan \dfrac{\theta}{2} = \dfrac{1 - 3/5}{4/5} = \dfrac{5-3}{4}=\dfrac{1}{2}$

Answer: 1/2

This is actually pretty deep. It says half the big acute angle in the 3/4/5 triangle is the small diagonal angle of the 1x2 rectangle. Similarly, the small acute angle in 3/4/5 triangle is twice the small diagonal angle of the 1x3 rectangle.

(-2,2)(2,-2)
slope = (-2 - 2) / (2 - (-2) = -4/4 = -1

as far as point slope form, there can be 2 answers...

y - y1 = m(x - x1)
slope(m) = -1
using points (-2,2)...x1 = -2 and y1 = 2
now we sub
y - 2 = -1(x - (-2) =
y - 2 = -1(x + 2) <== or could be written as y - 2 = - (x + 2)

y - y1 = m(x - x1)
slope(m) = -1
using points (2,-2)...x1 = 2 and y1 = -2
now we sub
y - (-2) = -1(x - 2) =
y + 2 = -1(x - 2) <== or can be written as y + 2 = - (x - 2)

either one of those answers is ur point slope form
