Answer:
there are one thousand (1,000) meters in a kilometer. So, 5,000 plus 10,000 is 15,000 meters.
Step-by-step explanation:
The inverse functions of sine, cos and tan functions are csc, sec and cot respectively.
<u>Step-by-step explanation:</u>
The reciprocals of sine, cos and tan functions are csc, sec and cot functions. The reciprocal of cosine function is secant, (sec) sec θ = 
The inverse or reciprocal function is cosecant (csc), 
The inverse tangent function is cotangent (cot) , expressed in two ways: 
or 
So 
then its reciprocal or inverse is termed as cot θ.
Answer:
Logan - 7 hours
Sarah - 6 hours
Step-by-step explanation:
Given Logan can iron 40 shirts per hour, and Sarah can iron 35 shirts per hour.
Also given that they worked together a combined hours of 13 hours
Let the number of hours worked by Logan is x and the number of hours worked by Sarah be y hours
Given x + y = 13
Also given that they together ironed 490 shirt's
which means 40x + 35y = 490
solve the above two equations by elimination
Multiply the first equation with 35 and subtract from the second equation we get
40x - 35x = 490 - 455
5x = 35
x = 7 hours
Substitute this value in the first equation to get the values of y
x + y = 13
y = 13 - x
y = 13 - 7 = 6 hours
therefore the number of hours worked by Logan is 7 hours and the number of hours Sarah worked is 6 hours
