Answer:
Triangle E
Step-by-step explanation:
(x,y) --> (y,-x)
Answer:
Out of all the choices given A. seems to fit best.
The initial value is 500 so the beginning should be A(n) = 500
The rate of increase is 4% so you would put that into decimal form of 0.04
Then you plug in 0.04 into (n - 1) and since we know that it is increasing you would put (1 + 0.04)
And the question asked to find the account's balance at the beginning of year 5 so plug 5 into n in the equation
A(n) = 500(1 + 1.04)^5 = 608.33
Hope this helps!
The first figure, on left, is the composition of two areas, the area of a 7cm circle and the area of a 7 cm square so:
A=7^2+7^2π/4
A=49+49π/4
A=49(1+π/4) cm^2
A≈87.48 cm^2 (to nearest hundredth of a square centimeter)
...
The second figure is the area of a 15cm by 8cm rectangle minus the area of a 3cm circle so:
A=15(8)-3^2π/4
A=120-9π/4
A=120-2.25π cm^2
A≈112.93 cm^2 (to nearest hundredth of a square centimeter)
7k/3 = 21
x 3 x3
7k = 63
/7 /7
k = 9
(7(9)/3 = 21 = 63/3 = 21 = 21 = 21)
