Answer:
0,0
Step-by-step explanation:
The function set is empty
3(4)+6
If you were 18, you would multiply 3 by 4 and add 6 to equal 18 (your age)
Answer: 2 cans.
Step-by-step explanation:
Calculate the volume of the go cart tank, which has the form of a rectangular prism. You can use the following formula:
![V=l*w*h](https://tex.z-dn.net/?f=V%3Dl%2Aw%2Ah)
Where:
l: is the lenght.
w: is the width.
h: is the height.
In this case:
![l=15.4in\\w=10in\\h=3in](https://tex.z-dn.net/?f=l%3D15.4in%5C%5Cw%3D10in%5C%5Ch%3D3in)
Substitute values into the formula. Then:
![V=(15.4in)(10in)(3in)=462in^3](https://tex.z-dn.net/?f=V%3D%2815.4in%29%2810in%29%283in%29%3D462in%5E3)
If a gas can holds 1 gallon of gas and
, then the number of full gas cans that will take to fill the go cart's tank (whose volume is 462 in³) is:
![gas\ cans=\frac{(462in^3)(1can)}{(231in^3)}=2\ cans](https://tex.z-dn.net/?f=gas%5C%20cans%3D%5Cfrac%7B%28462in%5E3%29%281can%29%7D%7B%28231in%5E3%29%7D%3D2%5C%20cans)
Answer:
zero
Step-by-step explanation:
The answer to that question is best found by looking at the value of the <em>discriminant</em>.
For quadratic ax^2 +bx +c = 0, the value of the discriminant is ...
d = b^2 -4ac
Here, you have a=3, b=8, c=7, so the discriminant is ...
d = 8^2 -4(3)(7) = 64 -84 = -20
When the discriminant is negative, both solutions are complex (not real).
There are zero real solutions to this equation.
Answer:
Initial population is 3450 in the year 2000 and it decreases 80 every year.
Step-by-step explanation:
We are given with y=-80x+3450 where y is city's population and x is the number of years after 2000.
That is x=0 means the year 2000.
Hence y-intercept will represent the initial population which is nothing but 3450.
Since our equation slope =-80 which is negative means y is decreasing as x increases.
For x raises by 1, y decreases by 80.
That means population decreases by 80 for every year.
