I’ll award you brainliest if you answer This question
guajiro [1.7K]

Answer:

$2353 at 12.5% and $7647 at 8.25%

Step-by-step explanation:

I'll say a is the amount he invested in one market, and b is the amount in the other.

a + b = 10000, or b = 10000 - a

multiplying the investments with the percentages and adding them together will give the total earned interest.

(a × 0.125) + (b × 0.0825) = 925

0.125a + 0.0825b = 925

Use substitution to solve for a.

0.125a + 0.0825(10000 - a) = 925

0.125 a + 825 - 0.0825a = 925

0.0425a = 100

a = 2352.94

Use substitution to find b

b = 10000 - 2352.94

b = 7647.06

The questions are to the nearest dollar so round a and b.

$2353 and $7647

Find all values of x in the interval [0,2π] that satisfy the equation sin2x=cosx. enter your answers as a list of numbers separa
yuradex [85]

\sin(2x)  =  \cos(x)  \\ 2 \sin(x)  \cos(x) =  \cos(x)  \\  \cos(x) (2 \sin(x)  - 1) = 0
so
\cos(x)  = 0 >  >  > x =  \frac{\pi}{2}  + k\pi \\  \sin(x)  =  \frac{1}{2}  >  >  > x =  \frac{\pi}{6}  + 2k\pi \\ or \: x =  \frac{5\pi}{6}  + 2k\pi
x =  \frac{\pi}{2} or \frac{3\pi}{2} \\  x =  \frac{\pi}{6} or \frac{5\pi}{6}
