Answer:
Step-by-step explanation:
• AB, BC, and AC form a triangle. Enter a possible value of AC....
So it asks for only a possible value of AC as there are many possible values.
Given AB = 8 cm and BC = 6 cm, they are in the ratio of 3:4.
Line segments of 3, 4 and 5 length will form a right-angled triange.
A possible value of AC = 5*2 = 10cm
• Points A, B, and C lie on the same line, and C lies between A and B.
So AC+CB = AB
AC+6 = 8
AC = 2cm
Enter this value of AC in the second
response box.
Answer:
Step-by-step explanation:
We can simplify (cross multiply) to get 
Then we easily simplify to get 
-2 pennies, 4 nickels, 4 dimes
-2 pennies, 4 nickels, 3 dimes
-2 pennies, 4 nickels, 2 dimes
And so on. Do you kind of get the idea?
Im not sure why you said ur wrong b/c i got the same answer
f(x) = -15+ 7
f(x) = -8
Answer:
0.707
Step-by-step explanation:
cos in the 4th quadrant is positive as well as in 1st quadrant.
cos(-45°) is in the 4th quadrant.
So cos40° must equal cos(-45°) which is 0.707.
