Answer:
y=(1/4)x + 9 OR y=x/4 +9
Step-by-step explanation:
Perpendicular lines have a slope/gradient of -1/n
Because the slope of this line is -4, the slope of a line perpendicular to it would be 1/4.
y=(1/4)x+b
(0,9) is the y-intercept, so b = 9
y=(1/4)x + 9 OR y=x/4 +9
Answer:
<em>35.11 ft</em>
<em></em>
Step-by-step explanation:
This given situation can be thought of as triangle
where PQ is the length of pole.
PR is the length of rope.
and QR is the distance of bottom of pole to the point of fastening of rope to the ground.
And 
Given that:
PQ = 44 ft
PR = 51 ft

To find:
Side QR = ?
Solution:
We can apply Sine Rule here to find the unknown side.
Sine Rule:

Where
a is the side opposite to 
b is the side opposite to 
c is the side opposite to 

Now,

Let us use the Sine rule again:

So, the answer is <em>35.11 ft</em>.
Answer:
Answer: D) 3.75
Step-by-step explanation:
According to the Insersecting chords theorem, when you multiply the lengths of the segments of one of the chords in a circle, the product obtained is equal to the product of the segments of the other chord.
Based on this, you can find the value of "x" with:
Solve for "x" (Applying the Division property of equality, you can divide both sides of the equation by 4). Then:
This value matches with the option D.
