Original line: y=1/2x-9
Perpendicular lines have opposite slopes from the original lines. Since the original slope is 1/2, the perpendicular slope will be -2/1 or -2. The numbers switch places and switches from positive to negative.
New line: y=-2x+b
To solve for the y-intercept (b), plug the given coordinates (3,2) into the x and y spots in the equation:
2=-2(3)+b
Now, solve for b.
2=-6+b
Add 6 to both sides.
8=b
The y intercept is 8.
Now, your perpendicular line equation is:
y=-2x+8
I hope this helps :)
We will use the area formula when we know 2 sides and an included angle.Area = (1/2) * 13 * sine (44.8) * 13Area = (1/2) * 169 * 0.70463Area =

The side length of the new square would be 9. When you dialate you multiply by the square factor, so 1/2 times 18 equals 9.
Answer:
77 approx
Step-by-step explanation:
Given data
Number of customers talked to per hour= 8
Hence for 8 hours(a day) the number of customers talked to = 8*8= 64
We want to first find 20% of 64
=20/100*64
=0.2*64
=12.8
Hence the number of customers will be
=12.8+64
=76.8
=77 approx
Answer:
3/4.
Step-by-step explanation:
The mean is 1/2*(1/2 + 1)
= 1/2 * 3/2
= 3/4.
