Answer:
You just need to put the given value of x-input in function f(x)=2x²+6x-8 to get y-output
Answer:
x = 12
Step-by-step explanation:
These are corresponding angles, so they're equal to each other:
9x - 13 = 6x + 23
9x - 6x = 23 + 13
3x = 36
x = 12
The amount of the down payment is
1,040×0.13=135.2
So the amount she has to pay after making the down payment is
1,040−135.2=904.8
It's d
To model half-life, use the formula
![A(t)=A_0 (\dfrac{1}{2})^{ \frac{t}{t_{1/2}}](https://tex.z-dn.net/?f=A%28t%29%3DA_0%20%28%5Cdfrac%7B1%7D%7B2%7D%29%5E%7B%20%5Cfrac%7Bt%7D%7Bt_%7B1%2F2%7D%7D%20)
. Here,
![A(t)](https://tex.z-dn.net/?f=A%28t%29)
is the amount remaining after a length of time
![t](https://tex.z-dn.net/?f=t)
.
![A_0](https://tex.z-dn.net/?f=A_0)
is the amount that you start with.
![t_{1/2}](https://tex.z-dn.net/?f=t_%7B1%2F2%7D)
is the half-life. You plug in 50 for
![t_{1/2}](https://tex.z-dn.net/?f=t_%7B1%2F2%7D)
, 10 for
![A_0](https://tex.z-dn.net/?f=A_0)
, and 25 for
![t](https://tex.z-dn.net/?f=t)
. You get
![A(t)=10( \frac{1}{2})^{25/50} = 10( \frac{1}{2})^{1/2} = 7.07 \ grams](https://tex.z-dn.net/?f=A%28t%29%3D10%28%20%5Cfrac%7B1%7D%7B2%7D%29%5E%7B25%2F50%7D%20%3D%2010%28%20%5Cfrac%7B1%7D%7B2%7D%29%5E%7B1%2F2%7D%20%3D%207.07%20%5C%20grams)
