572000 square miles rounded ro the nearest hundred thousand

1 answer:

7 0

It would be rounding it to 600000 because 600000 is the closest 100000x amount where x is an integer. I hope this helped and if I am right could I have brainliest? :)

8. Loren already knows that he will have $500,000 when he retires. If he sets up a payout

Ulleksa [173]

The annuity could provide $221.19 each month

Step-by-step explanation:

The ANNUITY FORMULA is $P_{t}=\frac{d[(1+\frac{r}{n})^{nt}-1]}{\frac{r}{n}}$ , where

1. $P_{t}$ is the balance in the account after t years

2. d is the regular deposit (the amount you deposit each year or month

or .........)

3. r is the annual interest rate in decimal

4. n is the number of compounding periods in one year

5. t the number of years

∵ Loren knows that he will have $500,000 when he retires

∴ $P_{t}$ = $500,000

∵ he sets up a payout annuity for 30 years in an account paying 10%

interest

∴ t = 30 years

∴ r = (10/100) = 0.1

∵ The annuity could provide each month

∴ n = 12

Substitute the values above in the formula

∴ $500,000=\frac{d[(1+\frac{0.1}{12})^{(12)(30)}-1]}{\frac{0.1}{12}}$

∴ $500,000=\frac{d[(1.00833333)^{360}-1]}{0.00833333}$

∴ 500,000 = d [2260.487925]

- Divide both sides by 2260.487925

∴ d = $221.19

The annuity could provide $221.19 each month

X^2(x^2+3x+2)plzz help me

agasfer [191]

The zeros for this function are -2, -1 and a double root of 0.

You can find this by first factoring the polynomial on the inside of the parenthesis. Polynomials like this can be factored by looking for two numbers that multiply to the constant (2) and add up to the second coefficient (3). The numbers 2 and 1 satisfy both of those needs and thus can be used as the numbers in a factoring.

x^2(x^2 + 3x + 2)

x^2(x + 2)(x + 1)

Now to find the zeros, we set each part equal to 0. You may want to split the x^2 into two separate x's for this purpose.

(x)(x)(x + 2)(x + 1)

x = 0

x + 2 = 0

x = -2

x + 1 = 0

x = -1

There is a bowling ball with a diameter of 216 mm and a baseball with a diameter of 74 mm. Find how many times greater the volum

zmey [24]

Bowling ball radius = 108 mm
Sphere Volume = 4/3 • π • r³
bowling ball volume = 4/3 * PI * 108^3
bowling ball volume = 5.2767e+6
 bowling ball volume = 5,276,669 cubic mm

baseball radius = 37 mm
baseball volume = 4/3 * PI * 37^3
baseball volume = 4/3 * PI * 37^3
 baseball volume = 212,174 cubic mm

bowling ball greater than baseball by a factor of:

5,276,669 / 212,174 = 24.8694450477 
answer is D
