Answer:
a) 4.392317 mt
b) 9 seconds
c)
Step-by-step explanation:
We have
where t is given in seconds and t in meters.
<em>a)How far has the point traveled 21 seconds after it started moving?</em>
By replacing t=21 in our equation we get
<em>b)If the point has traveled 3.16993 meters, how many seconds have elapsed since it started moving?</em>
We need to find a t such that f(t) =3.16993.
This can be accomplished by using the definition of
<em>c)Write a function that determines the number of seconds that have elapsed since the particle started moving in terms of the distance (in meters) the particle has traveled.</em>
is given by the definition of log
Answer:
(8x-10)/2
Step-by-step explanation:
Answer:
x= -1 and y =7
Step-by-step explanation:
To solve by elimination, multiply the entire first equation by 2 so that your x terms have the same coefficients.
2*(9x+2y=5) becomes 18x+4y=10.
Now stack and add each like term.
18x+4y=10
-18x-3y=-3
----------------------
0x +y = 7
y=7
Substitute y=7 into one of the original equations and solve for x.
9x +2(7) = 5
9x + 14 = 5
9x = -9
x=-1
Hello!
To find out if this food is enough we will add together all of the prices and multiply it by three to see if it is enough.
3(4.89+5+8.49)=55.14
Yes! They will have enough money with $4.86 to spare!
I hope this helps!
