goblinko [34]3 years ago
6 0

Answer:

(4, - 2 )

Step-by-step explanation:

Given the 2 equations

x = 4 → (1)

- y = \frac{1}{2} x → (2)

Substitute x = 4 into (2)

- y = \frac{1}{2} × 4 = 2 ( multiply both sides by - 1 )

y = - 2

Solution = (4, - 2 )

If csc 0=8÷7 which equation represents cot 0
Dahasolnce [82]

Answer: Cot\theta =\frac{\sqrt{15} }{7}

Step-by-step explanation:

Since, given cosec\theta=\frac{8 }{7}

And we know that Cot\theta=\sqrt{cosec^2\theta-1}

Therefore, Cot\theta=\sqrt{cosec^2\theta-1} = \sqrt{(8/7)^2-1}= \sqrt{64/49-1}

⇒Cot\theta=\sqrt{64-49/49}=\sqrt{15/49}=\sqrt{15}/7

Thus,  Cot\theta =\frac{\sqrt{15} }{7}

If the positive x-axis points to the right and the x-component of velocity is negative, a cart must be moving to the left.
Keith_Richards [23]
<h3>Answer: True</h3>

A negative velocity means the object is going the opposite way of the positive direction. So a negative x component velocity is pointing the opposite way (left) of the positive direction (right). You can think of it as the cart is backing up as it faces the positive direction.
