Answer:
new slope = 4/3
Step-by-step explanation:
-3/8 is perpendicular to the new slope
=> new slope = -8/3 * -1/2
= 8/6
= 4/3
please give me brainliest if it is helpful for you
Add the equations together:
12x-12x-11y-5y=40+88
you get
-16y=128
divide y=128/-16
y=-8
then plug-8 for y back into either equation.
12x-11(-8)=88
12x+88=88
12x=0
x=0
Problem 3
Circumference = pi*diameter
C = pi*d
C = 3.14*7.6
C = 23.864
C = 23.9
<h3>Answer: 23.9 cm</h3>
=======================================
Problem 4
A = area of square
A = side*side
A = 8*8
A = 64 square cm
B = area of circle
B = pi*r^2
B = 3.14*(5.5)^2 .... radius = 5.5 is half of diameter = 11
B = 94.985
C = area of shaded region
C = B - A
C = 94.985 - 64
C = 30.985
<h3>Answer: 30.985 square cm</h3>
=======================================
Problem 5
diameter = 6
radius = 3
area = pi*radius^2
A = pi*r^2
A = pi*3^2
A = 9*pi
A = 9*3.14
A = 28.26
<h3>Answer: 28.26 square millimeters</h3>
