Answer:
1.) 1/2 or 50%
Step-by-step explanation:
Lemme take sum time to do 2, 3, and 4!
Answer:
c. 18 units
Step-by-step explanation:
Points F and K are 3 units apart. (Both are on the horizontal line at y=2, so the segment length is the difference of x-coordinates: 4 -1 = 3.)
Points F and K are adjacent vertices of the hexagon, so the perimeter will be 6 times the length of KF: 6·(3 unit) = 18 units.
I must assume that you meant <span>X^2-10x =7. If that is indeed the case, then:
</span>X^2-10x =7 => x^2 -10x + 25 - 25 = 7, so that (x-5)^2 = 32 (Add 25, then
subtract 25)
Then x-5 = plus or minus sqrt(16)sqrt(2) = 4sqrt(2).
Then x = 5 plus or minus 4 sqrt(2) (answers)
=sin30cos60 + sin60cos30
=(1/2)(1/2) + (√3/2)(√3/2)
=1/4 + 3/4
=1+3/4
=4/4
=1
