The answer to your questions would be “46 degrees” :) you’re welcome
Last one and first. You can find out why by isolating the cube root and cubing both sides.
Answer:
0.055
Step-by-step explanation:
You want to move the decimal from the % left two places.
When a quadratic equation ax^2+bx+c has a double root, the discriminant,
D=b^2-4ac=0
Here
a=2,
b=b,
c=18
and
D=b^2-4ac=b^2-4*2*18=0
solve for b
b^2-144=0
=> b= ± sqrt(144)= ± 12
So in order that the given equation has double roots, the possible values of b are ± 12.
A. parallelogram
B. I believe it'd be around (11.2,7.5)
C. √(10-5)^2+(9-4)^2 = 21, so yes they bisect
