I’m probably wrong but I Think its isometric.
0.03x+0.035 (5000-x)=155
Solve for x
X=4000 invested at 3%
5000-4000=1000 invested at 3.5%
Answer:
Step-by-step explanation:
Take the old value - the new value. then divide that by the old value.
For the first question which is y=x/3, here as we see that both are in top. So they represents direct variation and constant of variation is 1/3 .
For the second question , which is 6/y=x, y is denominator and x is in the denominator. So they represents inverse variation and the constant of proportionality is 6 here .
1)
-280
= -14<span>π / 9
answer is B.
----------------------
2)
3</span><span>π/ 5
</span><span>= 108
answer
C. 108 degrees
3)
cos (3</span>π/4) = -√2 / 2
sin ((3π/4) = √2 / 2
cos (3π/4) and sin ((3π/4) = -√2 / 2 * √2 / 2

answer is
</span> -√2 √2
