The answer is the same as the question. 1.75
Answer:
v = 7
Step-by-step explanation:
step 1- make a line down the euqal sign
step 2 - subtract 0.1 and 0.1 and it will equal o and then add 0.1 under 2.2
step 3 -divide 0.3 from 2.2-0.1
hope this this helps :)
Answer:
The halflife of goo is 12 minutes
Step-by-step explanation:
Use formula
![A=A_0\cdot \left(\dfrac{1}{2}\right)^{\frac{t}{k}}](https://tex.z-dn.net/?f=A%3DA_0%5Ccdot%20%5Cleft%28%5Cdfrac%7B1%7D%7B2%7D%5Cright%29%5E%7B%5Cfrac%7Bt%7D%7Bk%7D%7D)
In your case,
![A_0=292\\ \\A=9.125\\ \\t=60](https://tex.z-dn.net/?f=A_0%3D292%5C%5C%20%5C%5CA%3D9.125%5C%5C%20%5C%5Ct%3D60)
Find k:
![9.125=292\cdot\left(\dfrac{1}{2}\right)^{\frac{60}{k}}\\ \\ \left(\dfrac{1}{2}\right)^{\frac{60}{k}}=\dfrac{9.125}{292}\\ \\ \left(\dfrac{1}{2}\right)^{\frac{60}{k}}=0.03125\\ \\ \left(\dfrac{1}{2}\right)^{\frac{60}{k}}=\dfrac{1}{32}\\ \\ \left(\dfrac{1}{2}\right)^{\frac{60}{k}}= \left(\dfrac{1}{2}\right)^{5}\\ \\\dfrac{60}{k}=5\\ \\5k=60\\ \\k=12](https://tex.z-dn.net/?f=9.125%3D292%5Ccdot%5Cleft%28%5Cdfrac%7B1%7D%7B2%7D%5Cright%29%5E%7B%5Cfrac%7B60%7D%7Bk%7D%7D%5C%5C%20%5C%5C%20%5Cleft%28%5Cdfrac%7B1%7D%7B2%7D%5Cright%29%5E%7B%5Cfrac%7B60%7D%7Bk%7D%7D%3D%5Cdfrac%7B9.125%7D%7B292%7D%5C%5C%20%5C%5C%20%5Cleft%28%5Cdfrac%7B1%7D%7B2%7D%5Cright%29%5E%7B%5Cfrac%7B60%7D%7Bk%7D%7D%3D0.03125%5C%5C%20%5C%5C%20%5Cleft%28%5Cdfrac%7B1%7D%7B2%7D%5Cright%29%5E%7B%5Cfrac%7B60%7D%7Bk%7D%7D%3D%5Cdfrac%7B1%7D%7B32%7D%5C%5C%20%5C%5C%20%5Cleft%28%5Cdfrac%7B1%7D%7B2%7D%5Cright%29%5E%7B%5Cfrac%7B60%7D%7Bk%7D%7D%3D%20%5Cleft%28%5Cdfrac%7B1%7D%7B2%7D%5Cright%29%5E%7B5%7D%5C%5C%20%5C%5C%5Cdfrac%7B60%7D%7Bk%7D%3D5%5C%5C%20%5C%5C5k%3D60%5C%5C%20%5C%5Ck%3D12)
The halflife of goo is 12 minutes
Answer:
y = 2x - 5
Step-by-step explanation:
Using the slope intercept formula y2 - y1 / x2 -x1...
You get a slope of 2 so y = 2x +b
Then to find b the intercept, you plug in one of the coordinates like so...
1 = 2(3) + b
Then solve to get an intercept of -5.
So the slope-intercept form would be...
y = 2x - 5
