Answer:
10 / 26
Step-by-step explanation:
cos <Z = adjacent / hypotenuse
= YZ / XZ
= 10 / 26
Answer:
D
Step-by-step explanation:
Common ratio of half means that to get each successive terms, you have to multiply the preceding term by half.
Since first term is 10
2nd term is 
3rd term is 
4th term is 
5th term is 
Answer choice D is right.
<span>Express 10 pints to 29 pints in simplest form.
The answer is 10/29 since 10 and 29 don't have a common factor to divide them both with. As a result, they stay as is 10/29 in already the simplest form. A is also in simplest form. B is in improper fraction form, also in simple form, can be turned into mixed number form. C is also in simplest form. The best answer is D since 10 pints to 29 pints is the instructions.</span>

Answer:
-5/4 +i(√2)/4 and -5/4 -i(√2)/4
Step-by-step explanation:
I find simplest form to be easier to get to if the leading coefficient is 1. Dividing by 16, we have ...
x^2 +5/2x +27/16 = 0
Completing the square by adding and subtracting the square of half the x-coefficient, we get ...
(x^2 +5/2x +25/16) +27/16 -25/16 = 0
(x +5/4)^2 = 2/16
Subtracting 2/16, taking the square root, and subtracting 5/4 gives ...
x +5/4 = ±√(-2/16)
x = -5/4 ±i(√2)/4
The roots are -5/4 +i(√2)/4 and -5/4 -i(√2)/4.
