Answer:
D.
Step-by-step explanation:
cos is positive and sin is negative
=>
it must be in quadrant IV.
you remember, 1 = sin² + cos²
1 = sin² + (3/5)² = sin² + 9/25
25/25 = sin² + 9/25
16/25 = sin²
sin = 4/5 or -4/5
and as sin of this angle is < 0, our solution is -4/5
The the scale factor is 9
You can do this by dividing the values of the sculpture by the model
For example:
L: 72/8 = 9
W: 54/6 = 9
H: 81/9 = 9
Answer:
Step-by-step explanation:
Fred does not shade any model
Edwards shades nine tenths : 0.9
Jeff shades shades seven tenths : 0.7
so add 0.9 + 0.7, you get 0.16 : sixteen hundredths .
1 and 2, because 1+2 is 3, which is less than 6, 2+3 is 5 which is also less than 6.
