Take 1/2 of liear coefient, and square it
-18/2=-9, (-9)^2=81
add 81
factors to (y-9)²
Step-by-step explanation:
To work out the total of doughnuts in the 4 boxes you have to multiply 6 by 4:
After that you need to work out how many each person will get by deviding 24 by 8:
That means each person received 3 doughnuts
Answer: 3
Answer:
14/25
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
12 split into 3 is four, because 4 x 4 x 4 (4 three times) is equal to 12
First one:
cos(A)=AC/AB=3/4.24
cos(B)=BC/AB=3/4.24
Cos(A)/cos(B)=AC/AB / (BC/AB) = AC/AB * AB/BC = AC/BC=3/3=1
Second one:
To solve this problem, we have to ASSUME AFE is a straight line, i.e. angle EFB is 90 degrees. (this is not explicitly given).
If that's the case, AE is a transversal of parallel lines AB and DE.
And Angle A is congruent to angle E (alternate interior angles).
Therefore sin(A)=sin(E)=0.5
