Answer:
Caiden
Step-by-step explanation:
We know that
[area of circular cookie]=pi*r²
r=2.5 in
[area of circular cookie]=pi*2.5²----> 19.63 in²
the answer is
the area of circular cookie is 19.63 in²
Answer:
-3
Step-by-step explanation:
If we directly evaluate the function at -1, we get 0/0, meaning we may still have a limit to find.
In this case, factoring the polynomial at the top would be helpful.
The polynomial can be factored to (x+1)(x-2), so the function would now turn out to be (x+1)(x-2)/(x+1)
The (x+1) cancel out, leaving you with (x-2), which you can directly evaluate by plugging in x as -1:
-1-2 = -3
Quick disclaimer: the function is still undefined at -1; it's just that the function gets closer and closer to -3 as you approach -1.
I hope this helped you.
To represent the number of grapes each person received using an algebraic expression, you will think of what is happening mathematically and use a variable to represent any unknown value.
x/5 would be the expression where x stands for the number of grapes Lester starts with.
To get the answer, you need to solve the equation for x = 7.
f(7) = 3/7 + 2 - sqrt(7) - 3.
= 3/7 - 1 - sqrt(7).
If you need to simplify it further:
= -4/7 - sqrt(7).
If you need it in decimal form: = -3.2171798824
