I don’t know if you meant b^2 and c^2 or b x 2 and c x 2 so I’ll do both.
If it’s meant to be multiplied by 2, then you do 9^2 + (40)2 =c2
81 + 80 = c2
161 = c2
/2
80.5 = c
However I do doubt it’s that. This means it’s likely meant to be squared instead. In which case, use the following answer.
9^2 + 40^2 =c^2
1681 = c^2
Then square root both sides to get just c (which i assume is what you’re trying to find?)
Square root of 1681 = 41
So your answer would be 41.
Answer:
c = 30.56 to the nearest hundredth
Step-by-step explanation:
87 = 9/5 c + 32
87 - 32 = 9/5 c
9/5 c = 55
multiply both sides by 5/9:
c = 55*5 / 9
c = 30.56.
Answer:
A.) y = 0.005x - 120
B.) You need more than 24,000 clicks to make a profit, or at least 24001 clicks.
Step-by-step explanation:
A.)
1. We know that the amount of money for each click is $0.005, which means that that's the amount of money you need to multiply by the number of clicks (or x) to find the amount of money you're making from the ads.
2. We also know that the cost to keep the website up is 120$, which is a loss of 120 dollars. To find the total profit in a month, you have to subtract whatever the profit from ads was by 120.
3. Since the amount from ads is 0.005 * x minus the cost of the website to be up, 120, the equation for the profit (or y) would be y = 0.005x-120
B.)
Next up is graphing it:
Geometry Way:
1. You can use any online graphing program, or hand graph it (I'll link one that I use in the comments--- Desmos).
2. Graph the equation.
3. Find the value in which that the profit would be 0. Anything more than that would be all of the values in which y is not 0 or negative.
Algebra Way:
1. Plug in 0 for y, or the profit.
2. Simplify. You'll find that when the profit is 0, the amount of clicks would be 24,000. Anything more than that would be positive.
Hope this helped!
The first thing to do with these problems is to convert them into y=mx+b form; this will literally show you the answer to slope and y intercept since m=slope and b=y intercept.
To convert, isolate the y and the rest should fall into place. Subtract 2x from 4y and the other side of the equation to get the equation 4y= -2x+9 (put the x first because of mx+b). Then Divide the 4 from y and do the same to the other side to get y= -1/2x+9/4. M= -1/2 so that is the slope. B=9/4 so that is the y intercept
