A student drops a penny from the top of a tower and decides that she will establish a coordinate system in which the direction of the penny's motion is positive. what is the sign of the acceleration of the penny?

Answers

Answer:

The sign of acceleration is positive.

Step-by-step explanation:

Consider the provided information.

It is given that A student drops a penny from the top of a tower and decides that she will establish a coordinate system in which the direction of the penny's motion is positive.

Here the direction of the velocity is positive, and the velocity is increasing.

Acceleration is defined as the rate at which an object changes its velocity.

Since velocity is positive therefore the acceleration is also positive.

Hence, the sign of acceleration is positive.

Answer:

It's positive

A 5-pound bag of apples cost $3.50. Use that rate, to complete the table to identify equivalent ratios, and then answer the questions. Apples *? 5 ? 15
Cost 0.70 3.50 7 ?

Apples cost $ __ per pound.

Answers

Well, all you need to do is divide $3.50 into 5 (because that means you are cutting it smaller, 5 ÷ 5 = 1, and you are dividing five 5 times)

Answer: It is $0.7 per pound.

Step-by-step explanation: All you have to do is divide $3.50 by 5 which gives you $0.7.

∠A = 106.3°, ∠B = 20.6°, ∠C = 53.1°

Step-by-step explanation:

In a ΔABC, the sides opposite to the angle A is a, angle B is b, and angle C is c. a = 60 , b= 22, c = 50

We can find any one angle by cosine rule,

a² = b² + c² - 2 bc cos (A)

60² = 22² + 50² - 2(22)(50) cos A

3600 = 484 + 2500 - 2200 cos A

3600 = 2984 - 2200 cos A

3600 - 2984 = -2200 cos A

616 = -2200 cos A

cos A = 616/ -2200 = -0.28

A = cos⁻¹ (-0.28) = 106.3°

Now we can use sine rule to find angle B as,

sin A/ a = sin B / b

sin 106.3° / 60 = sin B / 22

sin B = 22 × sin 106.3° / 60

B = sin⁻¹ (22 × sin 106.3° / 60 ) = 20.6°

As we know the sum of angles in a triangle is 180°.

∠A + ∠B + ∠C = 180°

106.3° + 20.6° + ∠C = 180°

126.9° + ∠C = 180°

∠C = 180° - 126.9° = 53.1°
