Calculate one tenth of an income of $12,347 by dividing by 10. 12.35 123.47 1,234.70 123,470

Answers

Answer: 1,234.70

Step-by-step explanation:

The given amount of income = $12,347

To find : One tenth of an income of $12,347

To calculate one tenth of an income of $12,347, we need to divide $12,347 by 10 ,we get

$12,347/10\n\n=(12,347 )/(10)\n\n=1,234.7$

On dividing a number by ten , we put decimal just before the first digit from the right.

Hence, One tenth of an income of $12,347 = 1,234.70

1,234.70. Hope this helps

Find the solutions to sin2(x) + cos(x) = 1, keeping 0 ≤ x < 2π

Answers

sin2(x) +cos(x)=1
from the relation: (sin2(x) +cos2(x) =1 )
so , sin2(x)=1-cos2(x)
by subs. in the main eqn.
1-cos2(x) + cos(x) =1
by simplify the eqn.
cos(x) -cos2(x)=0
take cos(x) as a common factor
cos(x)* (1-cos(x))=0
then cos(x)=0 && cos(x)=1
cos(x)=0 if x= pi/2
& cos(x) = 1 if x = 0 , 2*pi
so the solution is x= {0,pi/2 , 2*pi}

Answer:

Which statements did you include in your answer?

Isolate sin(x) by adding 4 and taking the square root of both sides.

State that sin(x) = 2 or sin(x) = –2.

State that –2 and 2 are undefined values of the inverse sine function.

There are no solutions because –2 and 2 are not in the domain of the function.

What two numbers add up to -53 and multiply to -24

Answers

assume the numbers are x , y
x+y =-53
x*y =-24
from equation 1 we get y = -53-x
sub in eqn.2
x* (-53 -x ) = -24
then x^2 + 53x -24 =0
and by solving the equation and substitute we get
the two numbers are
0.449 & -53.452
