Answer:
ig if it is brainiest
Step-by-step explanation:
y=1.75
Answer:
D
Step-by-step explanation:
To shift <em>h</em> units to the right, replace <em>x</em> with <em>x</em> - <em>h</em>
To shift <em>h</em> units to the left, replace <em>x</em> with <em>x</em> + <em>h</em>.
To shift <em>k</em> units up, add <em>k </em>to the end of the formula for the function.
To shift <em>k</em> units down, subtract <em>k</em> from the end of the formula.
Example: ![y=x^2](https://tex.z-dn.net/?f=y%3Dx%5E2)
is
shifted <u>left</u> 2 units and <u>up</u> 6 units.
Caution: the right/left shifts sometimes look backwards!
Answer:
18.51 grams.
Step-by-step explanation:
We have been given the decay rate
We have general equation for decay which is:
;![b=1-r](https://tex.z-dn.net/?f=b%3D1-r)
Here, we are given with initial sample which is a=300
b=1-13%
And t is 20 years.
We will subatitute the values in the formula we get:
![y=300\cdot (1-\frac{13}{100})^{20}](https://tex.z-dn.net/?f=y%3D300%5Ccdot%20%281-%5Cfrac%7B13%7D%7B100%7D%29%5E%7B20%7D)
![\Rightarrow y=300(\frac{87}{100})^{20}](https://tex.z-dn.net/?f=%5CRightarrow%20y%3D300%28%5Cfrac%7B87%7D%7B100%7D%29%5E%7B20%7D)
![\Rightarrow y=300(.87)^{20}](https://tex.z-dn.net/?f=%5CRightarrow%20y%3D300%28.87%29%5E%7B20%7D)
After simplification we get y=18.51 grams.
The sample remain will be 18.51 grams.
