Answer:
Use trig
Step-by-step explanation:
sin(55) = x/21
x = 21sin(55)
use calculator in degree mode
cos(55) = y/21
21cos(55) = y
3miles/ 28 minutes times 42 minutes is equal to 4.5 miles.
Therefore, Eric run 4.5 miles in 42 minutes.
Hopefully this helps!
Answer:
arc FD = 236°
Step-by-step explanation:
The measure of the arc is equal to the measure of the central angle it subtends, thus
arc FD = arc FE + arc ED = 146° + 90° = 236°
12 + 5x > 2(8x - 6) - 7x
12 + 5x > 16x - 12 - 7x
5x - 16x + 7x > -12 - 12
-4x > -24 / : (-4)
x < 6
For this case we have the following function:
By definition, we have that a linear equation is of the form 
On the other hand, a quadratic equation is of the form
Then, the given equation is not a linear equation, it is not of the form
Answer:
No, the equation is not linear. It is not of the form
