Sara will have a 3,360 interest fee.
Step-by-step explanation:
4% of 1,400 is 56. 56 X 60 = 3,360
I think it is a Convience Sampling.
For zeroes of r1,r2,r3, the factors of the function, f(x) are
(x-r1)(x-r2)(x-r3)
zeroes of -3,-5,2
(x-(-3))(x-(-5))(x-2)=
(x+3)(x+5)(x-2)
f(x)=(x+3)(x+5)(x-2)
expanded
f(x)=x³+6x²-x-30
Answer:
12a. 45+0.5x+2x+x = 150
12b. the three unknown sides are 30ft, 60ft, and 15ft.
Step-by-step explanation:
12a. the fence is 150ft. so
45+0.5x+2x+x = 150
12.b solve the equation from 12a.
45+0.5x+2x+x = 150
7x/2 = 105
7x = 210
x= 30
0.5(30) = 15ft
2(30)=30ft
x= 30ft
the three unknown sides are 30ft, 60ft, and 15ft.
Answer:
24 cent
Step-by-step explanation:
If 13 inches of wire cost 39 cent.
We have to calculate how much 1 inch of wire would cost first, before determining the cost of 8 inches of wire.
If 13 inches of wire costs 39cents, Then 1 inch of wire would cost 3 cent.
That is 39/13, which gives 3.
If 1 inch of wire cost 3 cents. Two inches of wire would cost 6 cents we 3 inches of wire costs 9 cents.
To get the cost of 8 inches of wire, we therefore multiply 8 by 3, which gives 24.
8 inches of wire costs 24 cents.
