Answer:
2
Step-by-step explanation:
The radical rule : ![\sqrt[3]{2^{3} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B2%5E%7B3%7D%20%7D)
= 2 when the number inside is greater than or equal to 0
Not sure what you mean by solution since that’s already simplified and inequalities don’t hav coordinate points as solution.
But -4<-3 so that point wouldn’t go into the “shaded area” of that inequality.
Hope this helps

Answer:
t = √(2d/a)
Step-by-step explanation:
To solve for a variable, undo the operations done to that variable, in reverse order. Here, t is squared, then multiplied by a/2.
d = (a/2)t^2
Multiply by 2/a.
2d/a = t^2
Take the square root.
t = √(2d/a)
We use letters to represent the unknown coins.
P for pennies that worth 1 cents
N for nickels that worth 5 cents
D for dimes that worth 10 cents
Q for quarters that worth 25 cents.
<span>"He has twice as many nickels (N) as dimes (D)" So D=2N
</span><span>"and four times as many pennies (P) as quarters (Q)." So Q=4P
</span>
Number of coins equals P+N+D+Q=P+N+2N+4P (Dimes and quarters are written in terms of nickels and pennies, respectively)
So, number of coins is equal to 5P+3N=201. Thats is the first equation (I)
To write the second equation, use cents of coins. 12.10 $ in coins can be shown as
5P. 1 cent + 3N. 5 cent=1210 cents or simply 5P + 15N=1210 (Second equation)
We have two equations and two unknowns so it is soluble.
number of coins: 5P+3N=201 (I)
cents of coins: 5P+15N=1210 (II)
Use the substitution method. (II) - (I)=12N=1009
N=1009/12=84 ( Actually it is 84.08)
D=2N=168
P= -10
Q=-40
Number of pennies and quarters are <span>meaningless. They can't be negative. So they should be something wrong in the question.</span>
