Answer:

x = 126.9° , x = 306.9°

Step-by-step explanation:

Given

3tanx = - 4 ( divide both sides by 3

tanx = - \frac{4}{3}

Since tanx < 0 then x is in 2nd / 4th quadrants

x = tan^{-1} (\frac{4}{3} ) ≈ 53.1° ← related acute angle

Then

x = 180° - 53.1° = 126.9°

x = 360° - 53.1° = 306.9°

Hi! Can someone help me please.
Sati [7]

Answer:

27 inches

Step-by-step explanation:

We are using the Pythagorean theorem

a^2 +b^2 = c^2  where c is the hypotenuse

We are given the diagonal, which is the hypotenuse and a leg

36^2 + b^2 = 45^2

Subtract 36^2 from each side

36^2 + b^2 - 36^2 = 45^2 - 36^2

b^2 = 45^2 - 36^2

     b^2 =2025-1296

          b^2 =729

Take the square root of each side

sqrt(b^2) = sqrt(729)

b =27

A force of 18 lb is required to hold a spring stretched 8 in. beyond its natural length. How much work W is done in stretching i
Wittaler [7]

Answer: 18.75 lb.ft

Step-by-step explanation:

Given

Force required to stretch spring 8 in. is 18 lb

it can be written

\Rightarrow F=kx\\\Rightarrow 18=k(8)\\\\\Rightarrow k=\dfrac{18}{8}=\dfrac{9}{2}\ lb/in.

Work done in stretching from its natural length to 10 in.

\Rightarrow W=\dfrac{1}{2}kx^2\\\\\Rightarrow W=0.5\times \dfrac{9}{2}\times (10)^2\\\\\Rightarrow W=225\ lb.in.\ or\\\Rightarrow W=18.75\ lb.ft
