Answers

Answer 1

Answer:

Cos (5π/3)

Cos (π/6)I think this one

Answer 2

Answer:

Below in bold.

Step-by-step explanation:

The sine is positive in the first and second quadrants and negative in other 2.

The cosine is positive in the first and 4th quadrants and negative in other 2.

Note that sin(pi/6) = 1/2 and cos(pi/3 = 1/2).

sin(7pi/6) = 1/2  

cos(5pi/3) = 1/2

sin(5pi/6) = 1/2

(x−2) 2 +(x+8) 2 =10


Please Explain ASAP

Answers

Answer:

x= -0.5

Step-by-step explanation:

2x-4+2x+16=10

4x+12=10

4x=-2

x=-1/2

Step-by-step explanation:

(x-2) 2 +(x+8) 2 = 10

x-2 + 2× x 2×8 + 2 = 10

x - 2 + 2x + 16 + 2 = 10

x + 2x + 16 - 2 + 2 = 10

3x + 16 = 10

3x = 10-16

3x = -6

3x÷3x = 6 ÷ 3

x = -2

ALGEBRA 1 MATH PLEASE HELP !!!!

Answers

Answer:

g(x) = |x-10|

Step-by-step explanation:

In majority of cases, the h in an equation is the movement to the left and right. and if you subtract h, you move to the right, if you add h, you move to the left. So in this case, to move ten units to the right, you would have h=10. Because there are no other changes made to the equation, the new equation, g(x), is simply:

g(x) = |x-10|

7. Choose the correct answer. If there is direct variation and y= 27 when t= 4, find y when = 12.

a. 9

b. 0.56

c. 81

d. 1.78​

Answers

Answer:

c

Step-by-step explanation:

Given direct variation between y and t , then the equation relating them is

y = kt ← k is the constant of variation

To find k use the condition y = 27 when t = 4 , then

27 = 4k ( divide both sides by 4 )

6.75 = k

y = 6.75t ← equation of variation

When t = 12 , then

y = 6.75 × 12 = 81
