Answer:

1 and 3/4 days are equal to 42 hours

Step-by-step explanation:

42 hours = (42 hours) (1 day / 24 hours)

42 hours = 42/24 days

Simplyfing the fraction: Dividing the numerator and denominator by 6:

42 hours = (42/6) /  (24/6) days

42 hours = 7/4 days

42 hours = (4+3)/4 days

42 hours = (4/4+3/4) days

42 hours = 1 3/4 days

Use the value of the first integral I to evaluate the two given integrals. I = integral^3_0 (x^3 - 4x)dx = 9/4 A. integral^3_0 (
Troyanec [42]

Answer:

A) -9/2

B) 9/4

C) -9/2, same as A)

Step-by-step explanation:

We are given that I=\int_0^3 x^3-4x dx=9/4. We use the properties of integrals to write the new integrals in terms of I.

A) \int_0^3 8x-2x^3 dx=\int_0^3 -2(x^3-4x) dx=-2\int_0^3 x^3-4x dx=-2I=-9/2. We have used that ∫cf dx=c∫f dx.

B) \int_3^0 4x - x^3 dx=-\int_0^3 (4x-x^3) dx=\int_0^3-(4x-x^3) dx=\int_0^3 x^3-4x dx=I=9/4. Here we used that reversing the limits of integration changes the sign of the integral.

C) It's the same integral in A)

PLS HELP ASAP NEED FOR A TEST
horrorfan [7]

Answer:

The answer in the procedure

Step-by-step explanation:

Let

x----> the first number

y----> the second number

we know that

\frac{x}{y}=\frac{3}{4}

so

y=\frac{4}{3}x -----> equation A

x+y=35 ----> equation B

substitute equation A in equation B

x+\frac{4}{3}x=35

\frac{3x+4x}{3}=35

\frac{7}{3}x=35    

x=35*3/7=15

y=35-15=20

In 2002, a certain town recorded 15,300 acres of underdeveloped land. Each year
Katyanochek1 [597]

The approximate amount of underdeveloped land in 2013 is A = 15300 X e^-0.07(11).

<h3>How do you determine the future value when there is continuous compounding? </h3>

The formula for calculating future value of an investment when there is continuous compounding is A = P x   e^{r}x N

Where:

  • P = population in 2002
  • r = rate of decrease = 0.07
  • n = number of years = 2013 - 2002 = 11 years

A = 15300 X e^-0.07(11)
