Step-by-step explanation:
Starts with 7x^2 then a term in x then a constant.
Answer:
The answer to your question is Perimeter = 287.3 in
Step-by-step explanation:
AB = 90 in
BC = 80 in
∠B = 50
Perimeter = ?
Process
1.- We need to find AC using Law of sines
A = 42.9 ≈ 43
The sum of the internal angles in a triangle equals 180°
A + B + C = 180°
43 + B + 50 = 180
B = 180 - 43 - 50
B = 87°
AC = 117.3
2.- Find the perimeter
Perimeter = AB + BC + AC
Perimeter = 90 + 80 + 117.3
Perimeter = 287.3 in
B = amount invested in B bonds
c = amount invested in CDs
so.. she's got $70000 burning a hole in her pocket and she wants to invest them to get a yield of 5000 in interest from both of them.
we know that, whatever "c" and "b" are, we know that
b + c = 70,000.
how much is 13% of b? well, (13/100) * b, or 0.13b
how much is 5% of c? well, (5/100) * a, or 0.05c
we know that, the yield or interest earned from them, must be 5000, thus
0.13b + 0.05c = 5000.
how much did she invest in CDs? well, c = 70000 - b.
