Answer:
87.5
Step-by-step explanation:
87.5 because if your earning a 3.5% of the $500 then that means you're earning 17.5 dollars.in an year therefore in five years you multiply the 17.5 x 5 years which will give you at 87.5 so we've had in total you can get to 587.5 dollars
Answer:
-5, multiplicity 3; +9, multiplicity 2; -1
Step-by-step explanation:
The roots of f(x) are those values of x that make the factors be zero. For a factor of x-a, the root is x=a, because a-a=0. If the factor appears n times, then the root has multiplicity n.
f(x) = (x+5)^3(x-9)^2(x+1) has roots ...
- -5 with multiplicity 3
- +9 with multiplicity 2
- -1
Answer:
12
Step-by-step explanation:
we can setup an equation and solve for x: 500-25x = 200, where x stands for the number of weeks she withdraws money.
subtract 500 from both sides to get -25x = -300.
multiply each side by -1 to get 25x = 300
divide each side by 25 to get that x = 12
Answer:
5.543 miles
Step-by-step explanation:
The law of cosines can help with this. It relates side "c" of a triangle to the other two sides (a, b) and the angle between them (C).
c² = a² +b² -2ab·cos(C)
c² = 3² + 3² -2·3·3·cos(135°) = 18(1 -cos(135°)) ≈ 30.7279
c ≈ √30.7279 ≈ 5.543 . . . . miles
