Answer:
A= 4.5×10^11
B= 3.5×10^3
Step-by-step explanation:
A
(5×10^3)= 5000
(9×10^7)=90000000
multiply both of them
=450000000000 or 4.5×10^11
B
(7×10^5)=700000
(2×10^2)=200
700000÷200
3500 or 3.5×10^3
first, find the numeric value for 11/15
second to find theta, simply do the <em>inverse</em> cos (which is cos^-1) of the first answer.
now you know theta, just do the sin of 90 - theta and that's it!
since you know whatr cos(theta) is, you just take the inverse cos of that number to get theta and 'reverse' cos, essentially. you are just solving for theta, by reversing the cos function with cos^-1

The function that could represent the value of a rare coin that increases over time is; y = ²/₃x + 2
<h3>How to create linear equations?</h3>
We want to find which of the equations below could represent the value of a rare coin that increases over time
y = -³/₂x + 1
y = -²/₃x - 7y
y = ²/₃x + 2
y = ³/₂x - 6
Now, the general form of a linear equation in slope intercept form is;
y = mx + c
where;
m is slope
c is y-intercept
Now, for the equation to be increasing over time, it means the slope must be positive and the y-intercept must also be positive.
Looking at the given options, the only one where slope and y-intercept is positive is y = ²/₃x + 2
