Answer:

The formula for the final velocity, bf in terms of initial velocity, v1, acceleration, a, and time is given as

bf=v1+a\times t

Step-by-step explanation:

Given:

a=\dfrac{bf-v1}{t}

To Find:

bf = ?

Solution:

Acceleration:

Acceleration is defined as the ratio between the change in velocity of an object and the time it takes for the object to change the velocity.

In formula, this is written as:

a=\dfrac{v_{f}-v_{i}}{t}

Where,

'a' is the Acceleration.

'vf' is the final velocity .

'vi' is the initial velocity.

't' is the time it takes for the object to accelerate from vf to vi

Here it is given as

a=\dfrac{bf-v1}{t}

So,

Where,

'a' is the Acceleration

'bf' is the final velocity .

'v1' is the initial velocity.

't' is the time it takes for the object to accelerate from bf to v1.

On  Solving the above equation 'bf' we get

a=\dfrac{bf-v1}{t}\\\\a\times t=bf-v1\\\\bf=v1+a\times t....As required

What is the expression in factored form? 9 x 2 − 4
attashe74 [19]

Answer:

(3x - 2)(3x + 2)

Step-by-step explanation:

9x² - 4 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

Thus

9x² - 4

= (3x)² - 2²

= (3x - 2)(3x + 2) ← in factored form

You are in a hot air balloon looking down at two ponds. Pond A which is in front of your balloon, is at an angle of depression t
MatroZZZ [7]

a. See attachment for the labelled diagram

b. Using the sine ratio, distance from the hot air to pond A is 5,038.9 m, while distance from the hot air to pond B is 6,287.1 m.

c. Distance between the two ponds is 1,263.5 m.

<h3>What is the Sine and Tangent Ratios?</h3>

Sine ratio, is: sin ∅ = opposite side/hypotenuse length

Tangent ratio is: tan ∅ = opposite side/adjacent length.

a. The diagram with the appropriate labels is shown in the image attached below.

b. Use the sine ratio to find the distance from the hot air to pond A (CA) and to pond B (CB):

CA = hypotenuse

∅ = 10°

Opposite = 875 m

sin 10 = 875/CA

CA = 875/sin 10

CA ≈ 5,038.9 m (distance from the hot air to pond A)

CB = hypotenuse

∅ = 8°

Opposite = 875 m

sin 8 = 875/CB

CB = 875/sin 8

CB ≈ 6,287.1 m (distance from the hot air to pond B)

c. Distance between the two ponds, BA = BD + DA.

Apply the tangent ratio to find BD and DA

tan 8 = 875/BD

BD = 875/tan 8

BD = 6,225.9 m

tan 10 = 875/DA

DA = 875/tan 10

DA = 4,962.4 m

Distance between the two ponds = 6,225.9 - 4,962.4 = 1,263.5 m.
