Answer: 14.1
Step-by-step explanation:
Law of cosines:
d^2 = 8^2 + 10^2 - 2(8)(10)cos103
Isn't it 16x-25 bc u subtract the cost?
Answer:
155.82 miles
Step-by-step explanation:
You multiply 6 and 25.97 to get your answer.
You need to list all of the possible outcomes. For example, Ham and Turkey, Ham and Lettuce, and so on. Make sure you list all of them. You will probably find that there is 42 in total. But, this is not an answer choice so what do you do? There will be doubles like when you say Ham and Turkey, you'll eventually say Turkey and Ham. But since you already listed the two, do not count Turkey and Ham. I hope this helps you!
Y=x^2+12x+30
8x-y=10
sub x^2+12x+30 for y in the secodn equaiton
8x-(x^2+12x+30)=10
8x-x^2-12x-30=10
-x^2-4x-30=10
times -1
x^2+4x+30=-10
add 10 both sides
x^2+4x+40=0
use quadratic formula
we find that we have 2 imaginary roots and therefor are not on the real plane, they are not plotted on the imaginary plane
no real solution
x=-2+6i or -2-6i
the interseciton on the imaginary plane is
(-2+6i, -26+48i) or (-2-6i,-26-48i)
