The annual rate of return of the investment that doubled in 15 years is 4.7%.
The annual rate of return of the investment that doubled in 8 years is 9 years.
The annual rate of return of the investment that doubled in 20 years is 3.52%.
The number of years it would take the investment to double is 9.97 years.

<h3>What are the annual rate of return?</h3>

The formula that can be used to determine the annual rate of return is:

g = (Future value / present value)^(1 / number of years) - 1

2^(1/15) - 1 = 4.7%

(1600 / 800) ^(1/8) - 1 = 9%

(200,00 / 100,000)^(1/20) - 1 = 3.52%

Number of years = (In FV / PV) / r

Where:

FV = future value
PV = present value
r = interest rate

IN2 / 0.0695 = 9.97 years

H(x) = x4+ 2x3- 10x2 -18x+9

vichka [17]

Let's group the cubic function: $h(x)=x^4+2x^3-10x^2-18x+9=(x-3)(x+3)(x^2+2x-1)$ .

The first two roots are $\pm3$ however to find the last two roots we need to solve the square equation:

$x^2+2x-1=0
\\D=b^2-4ac=2^2-4\cdot1\cdot(-1)=8$ . Now we know the discriminator, using the discriminator we're able to find the roots of the equation: $x_{1,2}=\frac{-b\pm\sqrt{D}}{2a}=\frac{-2\pm\sqrt{8}}{2}=\frac{-2\pm2\sqrt{2}}{2}=\frac{2(\sqrt{2}\pm1)}{2}$ . The roots of the square equation are $x_{1}=-1-\sqrt{2}$ and $x_{2}=\sqrt{2}-1$ .

The roots of the cubic function are $\pm3$ , $-1-\sqrt{2}$ and $\sqrt{2}-1$ .

Jesse borrowed $16,000 to purchase a new car. He borrowed the money from his local bank by taking out a loan that he would need

rodikova [14]

The answer is $630.57

You first need to add both the borrowed money and the interest then divide it all by 30

$16,000+$2,917.10= $18917.10

$18917.10/30= $630.57

PLEASEEE HELP !! What is the value of x ?

Shtirlitz [24]

Answer:

x = 20 cm

Step-by-step explanation:

The triangles given are similar triangles because they share the same angles. Because they are similar, their side lengths are in the same ratio, or proportion to one another. The left side of the larger triangle has a length of 121cm + 11cm = 132cm where the smaller triangle only has a length of 11 cm. We can put these lengths into a ratio:

$\frac{larger}{smaller}=\frac{132}{11}=\frac{12}{1}$

Since the other side of the triangle would have to be in the same proportion, or ratio, we can set up the following proportion:

$\frac{12}{1}=\frac{(5x+10)+10}{10}=\frac{5x+20}{10}$

Use cross-multiplication: 5x + 20 = (10)(12) or 5x + 20 = 120

Subtract 20 from each side: 5x + 20 - 20 = 120 - 20 or 5x = 100

Divide and solve for 'x': 5x/5 = 100/5 or x = 20 cm
