<span>To estimate the number of years for a variable to double, take the number 70 and divide it by the growth rate of the variable. This rule is commonly used with an annual compound interest rate to quickly determine how long it takes to double your money.</span>

<span>So 70÷4.5 = <span>15.5555556. So the answer is B</span></span>

Choose the values that would complete the general solution for y= arctan (0.7002).

e-lub [12.9K]

Answer:

-145°, -325°

Step-by-step explanation:

The principal value of the arctangent of 0.7002 is 35°. The tangent function is periodic with a period of 180°, so the general solution is ...

y = (35 +180k) degrees . . . . . where k is an integer

Values from the given list include ...

-145°

-325°

_____

<em>Additional comment</em>

+35° and +215° would also be part of the general solution

30. Work out the next two terms, giving your answers as fractions decimals or percentages. The sequence below is linear. 0.6 75%

Klio2033 [76]

Answer:

The next two terms are: 1.05 and 1.20

Step-by-step explanation:

Given

$Sequence: 0.6, 75\%, 9/10$

Required

Write out the next two terms

Since it is a linear sequence; first, we calculate the common difference (d)

$d = 75\% - 0.6$ or $d = 9/10 - 75\%$

Express as decimals

$d = 0.75 - 0.6$ or $d = 0.9 - 0.75$

$d = 0.15$ (in both cases)

So, we add 0.15 to 9/10, to get the next term

$Next = 9/10 + 0.15$

$Next = 0.9 + 0.15$

$Next = 1.05$

Add 0.15 to 1.05, to get the next term

$Next = 1.05 + 0.15$

$Next = 1.20$

<em>The next two terms are: 1.05 and 1.20</em>

In 2014, The population of West Palm Beach, Florida was 99,919. Write The 2014 population of West Palm Beach in scientific notat

frez [133]

Answer:

$9.9919*10^4$

Step-by-step explanation:

we have

$99,919$

we know that

$99,919=9.9919(10,000)$

$10,000=10^4$

substitute

$9.9919(10^4)$

therefore

The 2014 population of West Palm Beach in scientific notation is equal to

$9.9919*10^4$
