Answer:

57 days

Step-by-step explanation:

Given that:

t(0) = 26000

Growth rate (S'(t)) = 80t^1/2

Targeted number of subscribers = 49000

Take the integral of the growth rate :

∫80t^1/2dt = [(80t^(1/2 + 1)) / 1/2 + 1] + C

[(80t^(1/2 + 1)) / 1/2 + 1] + C = (80t^3/2) / 3/2 + C

(80t^3/2) * 3/2 + C = (160/3)t^3/2 + C

(160/3)t^3/2 + C

Let C = t(0)

(160/3)t^3/2 + 26000 = 49000

(160/3)t^3/2 = 49000 - 26000

(160/3)t^3/2 = 23000

Multiply both sides by 3/160

t^3/2 = 23000* 3/160

t^3/2 = 69000/160

t^3/2 = 431.25

t^(3/2 * 2/3) = 431.25^2/3

t = 57.080277

t = 57 days (approx.)

Step-by-step explanation:

None of them have degrees over 90 degrees

sorry for the late reply lol

Answer:

∠TPR = right angle

∠SPQ = acute angle

∠QPT = obtuse angle

Right angles are 90°, acute angles are angles less than 90°, obtuse angles are angles more than 90°

Answer:

130 offices are in the building

Step-by-step explanation:

first 39/x = 30/100

secondly, you cross multiply 39 x 100 and 30 x x

100 x 39= 3900

3900/30 = 130

Answer:

ANS. = 130

30% or 30/100=39offices

use cross multiplication

100/30 x 39/1 (note 30/100 is inversed to 100/30) math. law

10/3 x 39/1 (using divisor 10)

10/1 x 13/1 (using divisor 3)

10 x 13 = 130

Ans = 130 offices

Ans.Checked

30% of 130 offices

30/100 x 130/1

3/10 x 130/1 (10 as divisor)

3/1 x 13/1 (10 as divisor)

3 x 13 = 39

39 offices

Answer:

621200000000000000

Step-by-step explanation:

(6.2×10^17 )+(1.2×10^15)

6.2×100000000000000000+1.2×10^15  ≈6.212⋅10^ 1  7

620000000000000000+1.2×10^15 ≈6.212⋅10^ 1  7

620000000000000000+1.2×1000000000000000≈6.212⋅10^ 1  7

620000000000000000+1200000000000000≈6.212⋅10^1  7

621200000000000000

Answer:

6.212×10^17

Step-by-step explanation:

[tex] = ( 6.2 \times {10}^{17} ) + (1.2 \times {10}^{15} )[/tex]

[tex] = (620 \times {10}^{15}) + (1.2 \times {10}^{15} )[/tex]

[tex] = 620 \times {10}^{15} + 1.2 \times {10}^{15} [/tex]

[tex] = (620 + 1.2)\times {10}^{15} [/tex]

[tex] = 621.2\times {10}^{15} [/tex]

[tex] = 6.212 \times {10}^{17} [/tex]

Answer:C

Step-by-step explanation:

Answer:

Divide the numerator, 5, by the denominator, 6, to express the fraction 5/6 as a decimal. You can do this on either a calculator or using long division by hand. The answer will equal 0.83333 with the number 3 repeating endlessly.

Step-by-step explanation:

We can write 5/6 into a decimal as 0.84.

The decimal numeral system is the standard system for denoting integer and non-integer numbers.

Given is to write 5/6 into a decimal.

We can write 5/6 as a decimal below -

Pythagora's theorem can be used to solve problems like this

Answer:

x=19

Step-by-step explanation:

8(3x-2)-8x=9(2x-6) Distribute.

24x-16-8x=18x-54   Combine like terms.

16x-16=18x-54         Subtract 16x from both sides (getting rid of a variable first  

-16x     -16x               is easier).

-16=2x-54                 Add 54 to both sides.

+54    +54

38=2x                       Divide both sides by 2.

Answer:

Step-by-step explanation:

Given the profit made by a company modeled by the function

p = -n² + 300n + 100,000

The company breaks even when p = 0

To get the number of boxes sold when the company breaks even, we will substitute p = 0 into the equation.

0 = -n² + 300n + 100,000

multiply through by -1

0 = n² - 300n - 100,000

n² - 300n - 100,000 = 0

(n² - 500n) + (200n - 100,000) = 0

n(n-500)+200(n-500) = 0

(n+200)(n-500) = 0

n+200 = 0 and n-500 = 0

n = -200 and n = 500

Since n cannot be negative

Hence n = 500

This means that the company breaks even when it sells 500 boxes
