prohojiy [21]

Answer:

75% of 200 = 50; 20% of 160 = 128

Step-by-step explanation:

200 (0.75) = 150

200 - 150 = 50

160 (0.20) = 32

160 - 32 = 128

Nate has an account that pays 2. 76% simple interest per year and wants to accumulate $3,090 in interest from it over the next 1

lana66690 [7]

We have given that,

interest rate = 2.76%

simple interest = 3,090

term = 15 years

<h3>What is the principle of simple interest?</h3>

$Simple Interest = Principal * interest rate * term$

$3,090 = Principal * .0276 * 15\\3,090 = Principal * 0.414\\3,090 / 0.414 = Principal\\7,463.77 = Principal$

Therefore,Nate should invest 7,463.77 to meet his goal.

Dmitrij [34]

Answer:

The result of the integration is $\frac{x^5}{5}$

Step-by-step explanation:

Integration of a power of x:

The integration of a power of x is:

$\int x^{n} dx = \frac{x^{n+1}}{n+1}$

In this question:

$n = 4$ . So

$\int x^{4} dx = \frac{x^{4+1}}{4+1} = \frac{x^5}{5}$

The result of the integration is $\frac{x^5}{5}$

Use the quadratic formula to find the complex solutions to the equation 10x2 – x + 9 = 0.

melomori [17]

Quadratic formula: (-b +/- sqrt(b^2 - 4ac)) / 2a

a = 10

b = -1

c = 9

1 +/- sqrt((-1)^2 - 4(10)(9)) / 2(10)

1 +/- sqrt(1 - 360) / 20

x = 1 +/- sqrt(359i) / 20

Hope this helps!
