Answer: v = 793.77 mph
Step-by-step explanation: Linear speed of a circular movement is calculated by using the formula:
v = ω.r
where
ω is angular velocity
r is radius of the path
<u>Angular</u> <u>velocity</u> is the rate of change of the angular position of an object with respect of time, i.e., is how fast an object changes its angular position with time:
The Earth takes 24 hours to complete a rotation, then angular velocity:
0.262 rad/h
At a location 40° north, radius is 3033.5 miles, so:
v = 0.262*3033.5
v = 793.77
<u>At latitude of 40°north, linear speed is </u><u>793.77mph</u>.
Answer:
y=1/2x-4
Step-by-step explanation:
y-y1=m(x-x1)
y+3=1/2(x-2)
y+3=1/2x-1
y=1/2x-4

I will solve for the length and the area and the perimiter
if the width is 5ft and the length is 5 times as long as it is wide then
W=5 and L=5W
subsitute 5 for W
L=5(5)
L=25
length=25ft
the perimeter=2(L+W)=2(25+5)=2(30)=60ft
the area=LW=(5ft)(25ft)=125ft²
Answer:
Angle L
Step-by-step explanation:
An obtuse angle has a measure between 90° and 180°.
Angles J and K are right angles, so their measures are equal and are 90°. Angle M has measure 64° and is acute.
Only angle L, which measures 116°, has a measure between 90° and 180° and is an obtuse angle.
Answer: Angle L
The pattern is multiplying each number by 4
