23. If M' represents the complementary, then is the answer A.
24. The answer is C.
Answer:
y=1/4x + 1.75
Step-by-step explanation:
1-2/2--2 = 1/4
2=1/4+b
b=1.75
1200 ÷ 4 = 300
Each person will receive 300 stock cards.
We have that
<span>y=2sinx-cosx
y=cosx
</span>over the interval 0≤x≤pi/2-------> 0≤x≤1.57
using a graph tool
see the attached figure
the solution in the given interval is the point (pi/4, 0.707)
the y-value of the point of intersection is 0.707 -----> √2/2
the answer is the option <span>
b. (square root of 2)/2</span>
2.1 x 10^10/ 7 x 10^17
= 3 x 10^-8
hope this helps and have a great day :)
