Answer:
4u= - 4i - 24j
u +w = -9i - 3j
Step-by-step explanation:
The question is on operation of vectors
Given u= -i -6j and w= -8i+3j
Then 4u = 4{ -i-6j}
4u= - 4i - 24j
u+w= -i -6j + -8i+3j......................collect like terms
= -i -8i + -6j +3j
= -9i + -3j
= -9i - 3j
It's
0.5=0.85^x take natural log of both sides...
ln0.5/(ln0.85)=x
x≈4.265 years the car's value will be half of its original value...
y=20000(0.85)^(4.265)
y=$10000.00
Here you want to find a common denominator. 12 is a good one. so you need to find out what the fractions will be if the denominator is 12.
How to do:
2*4=8
3*4=12
2/3=8/12
1*3=3
4*3=12
1/4=3/12
Now add those to see how many girls have brown or blue eyes.
8/12+3/12=11/12
Now do a whole minus 11/12.
12/12-12/12=1/12
So.... 1/12 of the girls do not have brown or blue eyes.
Hope this helps!
