Viola is travelling on an inclined path up the hill which makes an angle of 6 degrees with the horizontal.
The horizontal distance covered by Viola will be equal to the horizontal component of the 170 m distance covered at 6 degrees.
So, the horizontal distance covered by Viola = 170 cos(6) = 169.1 m
Thus, Viola covered 169.1 m horizontal distance
1. its 23, because if you were to substitute 5 for x, 7(5) = 35 and if you were to substitute -3 for y, 4(-3) = -12. Therefore, 35 + -12 = 23.
Answer:
Step-by-step explanation:
Slope intercept formula is y=mx+b
(m) is slope
(b) is the y intercept
We'll find slope first.
slope formula is
y2 and x2 are the y and x values of the second equation and y1 and x2 are the y and x values of the first equation.
So we just put the given values into our equation.
Simplify
Now we put this into our y=mx+b
y=0/-3x+b
now we need the (b)
to do this we take the values of one of the coordinates (doesn't matter which) and replace the (y) and (x) in our equation with them.
Solve
1=0+b
b=1
Put this in our formula

jaso saknihh Step-bnswerda po sha jasony-step explanation:
When you make a drawing with the instructions, and call x the altitude of the plane and y the distance from the angle 72 ° to the point straight below the plane, you obtain these equations
tan(55°) = x / (2.2 + y)
tan (72°) = x / y
You solve y from the second equation
y = x / tan(72°)
Substitute y in the first equation
tan (55°) = x /(2.2 + x/tan(72°)
Solve for x:
x = tan(55)[2.2 + x/tan(72) ]
x = tan(55) (2.2) + x tan(55)/tan(72)
x - x tan (55)/tan(72) = 2.2 tan (55)
Now substitute the values of the tangents
tan (55) = 1.4281
tan(72) = 3.0777
x - 0.464x = 3.1419
x = 3.1419 / (1-0.464) =5.86 m
Ah ... it is a toy plane! I guess.
