Answer:

4. 8.0

5. 27.6

6. 35.5 degrees

Step-by-step explanation:

#4- Cos 48= x/12

0.669131= x/12

x=8.0

#5

Sin 78= 27/x

0.978=27/x

0.978x=27

x=27.6

#5

Tan X= 15/21

tan x= .714

inverse tan= 35.5 degrees

3. Suppose a male and a female of a certain species of animal were taken to a deserted island. The population of this species qu
NeTakaya

Answer:

a) 2*4^n b)2048 c) n > 9.46578

Step-by-step explanation:

The initial population was the two parents ( male and female)

After first year, the population quadruples = 2*4 = 8

After second year, the population = 2*4*4= 32

After third year, the population = 2" 4*4*4

After n number of years, the population = 2*4^n

b) after 5years, the population = 2*4^5 =2048

C) for the population to exceed 1million the equation becomes 2*4^n > 1 000 000

4^n > 500000, take log of both side

nlog4 > log 500000

n > log 500000/log(4) > 9.46578

Add or subtract the following:<br><br> 5.75+479.39−25.03 Not sure how to do this?
neonofarm [45]
First do it in brackets: (5.75+479.39)= 485.14
Then subtract it : 485.14-25.03 = 460.11

I hope it helped you!

Which statement is true about the polynomial after it has been simplified. -10m^4n^3+8m^2n^6-6m^2n^6
laila [671]

Answer: 2m^2n^3 x ( -5m^2 + 4n^2 -3n^2 )

Step-by-step explanation:

<em>ok</em><em>,</em><em> so just let me</em><em>,</em><em> uh</em><em>,</em><em> make this a little easier on my eyes lol:</em>

-10m^4n^3+8m^2n^6-6m^2n^6 ----> (-10m^4)(n^3) + (8m^2)(n^6) - (6m^2)(n^6)

<em>I just put in parentheses. nothing changed. just parentheses. </em>

Since the leading coefficients, -10 , 8 , and 6 are multiples of two,

we can take out 2 from each... [-10/2 = 5 , 8/2 = 4 , 6/2 = 3 ]

= 2 x [ (-5m^4)(n^3) + (4m^2)(n^6) - (3m^2)(n^6) ]

Looking at it now...

<em>we can take out m^2 from each... </em>m^4 , m^2 , and m^2

m^2 [m^2 , 1 , 1]

since    m^4 /m^2 = m^2 , m^2 /m^2 = 1 , m^2 /m^2 = 1

= 2(m^2) x [ (-5m^2)(n^3) + (4x1)(n^6) - (3x1)(n^6) ]

= 2(m^2) x [ (-5m^2)(n^3) + (4)(n^6) - (3)(n^6) ]

Finally, one more step...

<em>we can take out n^3 from each term.... </em>n^3 , n^6 , and n^6

n^3 [1 , n^2 , n^2] since n^3 /n^3 = 1 , n^6 /n^3 = n^2 , n^6 /n^3 = n^2

= 2(m^2)(n^3) [ (-5m^2)(1) + (4)(n^2) - (3)(n^2) ]

= 2m^2n^3 x [ (-5m^2) + (4n^2) - (3n^2) ]

= 2m^2n^3 x ( -5m^2 + 4n^2 -3n^2 )

ANSWER: 2m^2n^3 x ( -5m^2 + 4n^2 -3n^2 )

<em>keep this parentheses. seriously. </em>
