Which is an incorrect rounding for 53.864

Answer:

The right answer is :

(a) 23,200

(b) 24,514

(c) 22,926

Step-by-step explanation:

According to the question,

[tex]P_1 = 12000[/tex]

[tex]P_2 = 20000[/tex]

[tex]P_{sat}=80000[/tex]

(a)

We know that the arithmetic growth formula will be:

⇒ [tex]P=Pi+K\times t[/tex]...(1)

here,

⇒ [tex]K=\frac{P_2-P_1}{\Delta t}[/tex]

        [tex]=\frac{20000-12000}{25}[/tex]

        [tex]=\frac{80000}{25}[/tex]

        [tex]=320[/tex]

On putting the values in equation (1), we get

⇒ [tex]P_{2020}=20000+320\times 10[/tex]

             [tex]=23,200[/tex]

(b)

The geometric growth formula will be:

⇒ [tex]P=ln(Pi)+K\times t[/tex]

here,

⇒ [tex]K=\frac{lnP_2-lnP_1}{\Delta t}[/tex]

         [tex]=\frac{ln(20000)-ln(12000)}{25}[/tex]

By putting the values of general log, we get

hence,

⇒ [tex]P_f=ln(20000)+0.0204\times 10[/tex]

         [tex]=10.107[/tex]

[tex]P_{2020}=e^{10.107}[/tex]

          [tex]=24,514[/tex]

(c)

⇒ [tex]P_f=P_{sat}-(P_{sat}-P_i)e^{-K\times t}[/tex]

or,

⇒ [tex]K=-\frac{1}{\Delta t}ln(\frac{P_{sat}-P_2}{P_{sat}-P_1} )[/tex]

from here, we get

        [tex]=0.005[/tex]

hence,

⇒ [tex]P_{2020}=80000-(80000-20000)e^{-0.005\times 10}[/tex]

             [tex]=80000-(60000)e^{-0.005\times 10}[/tex]

             [tex]=22,926[/tex]

Answer:

Step-by-step explanation:

since 3 is outside the parenthesis (n + 2) you multiply the 3 by the n and the 2 and

3n + 6

next subtract the 6 and add the 6 to the other side

3n - 6 = 6

3n = 6

n = 2

Answer:

Center = (-1, 1)

Radius = 3

Graphing form

(x + 1)² + (y - 1)² = 3²

General form

x² + y² + 2x - 2y - 7 = 0

Step-by-step explanation:

Center = (-1, 1)

Radius = 3

Graphing form

(x + 1)² + (y - 1)² = 3²

General form   \Expand graphing form\

(x² + 2x + 1) + (y² - 2y + 1) - 9 = 0

Rearrange

x² + y² + 2x - 2y - 7 = 0

Answer:

150

Step-by-step explanation:

Remark

The exterior angle = the sum of the two given interior angles. The first job is to solve for x and then use that to find the exterior angle.

Equation

83 + 6x + 7 = 15x              

Solution

Combine like terms

90 + 6x = 15x        Subtract 6x from both sides.

        6x     6x

90 = 9x                 Divide both sides by 9

90/9 = 9x/9

x = 10

Now the exterior angle = 15x

Exterior angle = 15*10

Exterior angle = 150

Answer:

B

Step-by-step explanation:

Cause he added 24.76 more pounds to the 3.6 pounds. So you can take 24+3=27 and you might think C, but 0.76+0.6 that equals more than 1, so 27+1=28, and B has 28 as its answer, so its B

Answer:

Randomly selecting a six of diamonds - 1 / 52

Randomly selecting a 7, 8, 9 or 10 - 4 / 13

Step-by-step explanation:

There is only 1 six of diamonds in a standard deck of cards. There are 52 cards in a deck, thus the probability of pulling a six of diamonds is 1 in 52.

There are 4 of each card in a deck. so they are 4 7's, 4 8's. 4 9's and 4 10's. And there are a total of 52 cards in a deck. So the probability of pulling a 7,8,9 or 10 are 4 + 4 + 4 + 4 in 52

4 + 4 + 4 + 4 = 16

16 / 52 simplified is 4 / 13 Therefore the is a 4 in 13 chance of pulling a 7 8 9 or 10

The other ones are correct
