Answer:

2.38% annual interest rate

Step-by-step explanation:

We have the initial value that is $6139 and the final value that is $8,624.97 the initial value is a 100% and the final value is 100%+17x%  where x is the annual interest rate, then:

\dfrac{8624,97\cdot 100\%}{6139\cdot (100\%+17x\%)}=1

\dfrac{8624,97\cdot 100\%}{6139}=100\%+17x\%

\dfrac{862497\%}{6139}-100\%=17x\%

140.49\%-100\%=17x\%

40.49\%=17x\%

\dfrac{40.49\%}{17}=x\%

2.38\%=x\%

Without using a calculator determine the number of real zeros of the function f(x) = x^3 + 4x^2 + x -6
hodyreva [135]
Try this:
x³+4x²+x-6=0
1) To re-write the equation into form:
1*x³+4*x²+1*x-6=0, the note 1+4+1=6, it means x=1
2) to re-write the equation into form:
(x-1)(x²+5x+6)=0
(x-1)(x+2)(x+3)=0
3)
\left[\begin{array}{ccc}x-1=0\\x+2=0\\x+3=0\end{array}\right \ \ \textless \ =\ \textgreater \   \left[\begin{array}{ccc}x=1\\x=-2\\x=-3\end{array}\right

erik [133]

Answer:

1. 23.0 cm

2. 21.0 ft

3. 31.0 yd

Step-by-step explanation:

1. 30/sin110 = RT/sin46

RT = sin46 × 30/sin110

RT = 22.96516279

2. Angle A = 180 - 61 - 53 = 66°

24/sin66 = AB/sin53

AB = sin53 × 24/sin66

AB = 20.98116966

3. 18/sin28 = HP/sin54

HP = sin54 × 18/sin28

HP = 31.01850475
