Answer:
2.34 grams
Step-by-step explanation:
In this problem, we need to find how many grams in 2.34mL. To solve the problem, we must know the relationship between grams and millilitre.
We know that,
1 milliitre = 1 gram
Hence,
2.34 mL = 2.34 grams.
Answer:
First do the case in which none of the digits is 0.
There are 9 ways to choose the digit that repeats 3 times and 8 ways to pick the other, after this there are 4 ways to order the digits. So 9×8×4.
Now we look at the cases in which the digit 0 repeats 3 times. Clearly the 9 numbers are 1000,2000,3000,…,9000.
Lastly we look at the cases in which 0 appears once. There are 9 ways to pick the other digit and 3 ways to order.
So the final answer is 9×8×4+9+9×3.
Answer:
Step-by-step explanation:
the function -16t^2 + 64t + 192 give the height S, in ft, of a model water rocket launched with a velocity of 64 ft/second from a hill that is 192 ft high. a) determine how long it will take the rocket to reach the ground, b) find the interval on which the height of the rocket is greater than 240 ft.
Answer:
if ![f(x)=-1](https://tex.z-dn.net/?f=f%28x%29%3D-1)
Step-by-step explanation:
Given --> ![f(x)=-\frac{3}{4}x-7](https://tex.z-dn.net/?f=f%28x%29%3D-%5Cfrac%7B3%7D%7B4%7Dx-7)
Substitute
into the equation and solve for
:
![-1=-\frac{3}{4}x-7](https://tex.z-dn.net/?f=-1%3D-%5Cfrac%7B3%7D%7B4%7Dx-7)
![6=-\frac{3}{4}x](https://tex.z-dn.net/?f=6%3D-%5Cfrac%7B3%7D%7B4%7Dx)
![24=-3x](https://tex.z-dn.net/?f=24%3D-3x)
![-8=x](https://tex.z-dn.net/?f=-8%3Dx)
So, when ![f(x)=-1,x=-8](https://tex.z-dn.net/?f=f%28x%29%3D-1%2Cx%3D-8)
