If James draws a diagonal line of length x from one right angle to the opposite right angle, then he divides his piece of paper into two pieces, each of them is right triangle with legs 9 inches and 12 inches.
By Pythagorean theorem:
 x^2=9^2+12^2 \\ x^2=81+144 \\ x^2=225 \\ x=15 inches.
Answer: 15 inches

Write an equation in slope-intercept form that describes the line through the points (-2,6) and (3, 1).
vladimir1956 [14]

Answer:

y=-x+4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(1-6)/(3-(-2))

m=-5/(3+2)

m=-5/5

m=-1

y-y1=m(x-x1)

y-6=-1(x-(-2))

y-6=-(x+2)

y-6=-x-2

y=-x-2+6

y=-x+4

The sun appears to move across the sky, because the earth spins on its axis. To a person standing on the earth, the sun subtends
Liono4ka [1.6K]

Answer:

128 seconds

Step-by-step explanation:

The sun subtends an angle \theta=9.28\times10^{-3} rad

Angular velocity equation is \omega = \frac{\theta}{t}

where \omega is angular velocity and t is time.

Earth spins at a rate of :

\omega = \frac{2 \pi rad}{24 h \times \frac{3600 s}{1 h}} = 7.27221\times10^{-5}  rad/s

Isolating time (t) from angular velocity equation gives:

\omega = \frac{\theta}{t}

t = \frac{\theta}{\omega}

t = \frac{9.28\times10^{-3}}{7.27221\times10^{-5}}

t = 128 s
