Find sin theta if cos theta is 4/5

Mathematics
1 answer:
Dima020 [189]3 years ago
5 0

Answer:

Step-by-step explanation:

hello :

cos²θ +sin²θ = 1 and cosθ =4/5

(4/5)² + sin²θ = 1 so : sin²θ = 1 - 16/25

sin²θ = 9/25 = (3/5)²

sinθ = 3/5 or sinθ = - 3/5 because : (3/5)²= (- 3/5)²= 9/25

We want to place a bench measuring 7.05 feet in the center of a platform that is 40.75 feet long. What is the distance from each
alexandr402 [8]

Answer:  The distance from each side of the bench to the edges of the platform = 16.85 feet.

Explanation:

Length of platform = 40.75 feet

Length of bench  = 7.05 feet

Let the distance from each side of the bench to the edges of the platform be x

So, it becomes x+7.05+x = 40.75

⇒2x+7.05= 40.75

⇒2x = 40.75- 7.05

⇒x = 33.7

⇒x=\frac{33.7}{2}

⇒x= 16.85 feet .

So, the distance from each side of the bench to the edges of the platform = 16.85 feet.

As Sally and George practice for the SAT their scores on practice test rise Sally’s current score is 850 and it is rising by 10
aleksley [76]

Answer:

a) 7 weeks b) George's

Step-by-step explanation:

Sally's score can be modeled by 10x+850.

George's score can be modeled by 50x+570.

We can set them equal to each other to see when they intersect.

10x+850=50x+570

40x=280

x=7

If George overtakes her in the 7th week, of course he'll have the higher score in 12 weeks.
