Answer:
Figure D
Step-by-step explanation:
we know that
If the scale factor of the dilation is 1/2, that means the dilation is a reduction
so
the answer is between the Figure C and Figure D
but
a rotation of 180° eliminate the Figure C
therefore
The answer is the Figure D
Answer:
(2,0)
Step-by-step explanation:
The plane will make an angle
with the runway.
Explanation:
Given that the plane is flying at an altitude of 11 miles and is 193 miles from the runway, as measured from the ground.
We need to determine the angle that the plane will make with the runway.
From the given measurements, we can see that it is a right angled triangle. Hence, let us use the tangent formula to determine the angle.
The formula for the tangent is given by

Where
and
Substituting these values in the above equation, we get,

Dividing, we get,

Taking
on both sides of the equation, we get,

Simplifying, we have,

Hence, the angle that the plane will make with the runway is 
Answer:
Step-by-step explanation:
hello :
you add 11² to complete the square
x²+22x+11²=50+11²
(x+11)² = 171
