Answer:

tan =-1

Step-by-step explanation:

tan(θ)=sen(θ)/cos(θ)

$tan(angle)=\frac{\frac{-\sqrt{2} }{2} }{\frac{\sqrt{2} }{2} } }\\tan(angle)=-1$

T=2π√l/g. Make l subject of the formula

Aliun [14]

Answer:

l = gt²/(2π)²

Step-by-step explanation:

if T = 2π√l/g

squaring both sides

(T)² = (2π)² × (√l/g)²

T² =4π² × l/g

T² = 4π²l/g

using cross multiplication techniqes

gT² = 4π²l

divede both sides by " 4π²"

gT²/4π² =4π²l/4π²

gT²/4π² =l

l = gT²/(2π)²

that is the final answer.

Find the slope of the line that passes through (-24, 90) and (-23, 52).

Ostrovityanka [42]

Answer:

-38

Step-by-step explanation:

The slope is rise over run. You need to find out how far one point is from the other. To do this, use the equation for slope.

$m=\frac{y_{2}-y_{1} }{x_{2}- x_{1} }$

Plug in the points given into the equation and solve for slope (m).

$m=\frac{y_{2}-y_{1} }{x_{2}- x_{1} }\\m=\frac{90-52 }{-24-(-23) }\\m=\frac{90-52 }{-24+23 }\\m=\frac{38}{-1} \\m=-38$

The slope of the line is -38.
