An object is dropped from a height of 1168 feet above the ground.

How high above the ground will the object be after 6 seconds?
Incorrect
feet
Correct

How long after being dropped will the object reach the ground? (if necessary, round to the nearest tenth)

Answers

Answer 1

9514 1404 393

Answer:

  592 feet

  8.5 seconds

Step-by-step explanation:

The usual equation used for ballistic motion is ...

  h(t) = -16t^2 +h0

Here, we have h0=1168 and t=6, so ...

  h(t) = -16(6^2) +1168 = 592 . . . feet high after 6 seconds

__

For h(t) = 0, the value of t can be found from ...

  0 = -16t^2 +1168

  t^2 = 1168/16 = 73

  t = √73 ≈ 8.5

The object will reach the ground after 8.5 seconds.

Please answer the following question on linear algebra.

Answers

T satisfies the homogeneity property.

To prove that T is a linear transformation, we need to show that it satisfies two properties: additivity and homogeneity.

Additivity:

Let's consider two arbitrary vectors z₁ = [x₁, y₁] and z₂ = [x₂, y₂] in R².

T(z₁ + z₂) = T([x₁ + x₂, y₁ + y₂])

= [-2(x₁ + x₂) - 1, -2(x₁ + x₂) + 2(y₁ + y₂)]

= [-2x₁ - 2x₂ - 1, -2x₁ - 2x₂ + 2y₁ + 2y₂]

= (-2x₁ - 1, -2x₁ + 2y₁) + (-2x₂ - 1, -2x₂ + 2y₂)

= T(z₁) + T(z₂)

Therefore, T satisfies the additivity property.

Homogeneity:

Let's consider an arbitrary vector z = [x, y] in R² and a scalar k.

T(kz) = T([kx, ky])

= [-2(kx) - 1, -2(kx) + 2(ky)]

= (-2kx - 1, -2kx + 2ky)

= k(-2x - 1, -2x + 2y)

= kT(z)

Since T satisfies both additivity and homogeneity, we can conclude that T is a linear transformation.

. The table below shows the cost of making a long distance call based on the length of the call. Long Distance Rates Time (minutes) Cost 5 $0.55 6 $0.62 7 $0.69 8 $0.76 9 $0.83 10 $0.90 Refer to the above table of long distance rates. Write an expression that can be used to find the cost of an n-minute long distance call, where n is at least 5 minutes.

Answers

An expression that can be used to find the cost of an n-minute long distance call, where n is at least 5 minutes is (0.55 + (n - 5) x 0.07) dollars.

Given:

Long Distance Rates Time (minutes) Cost5 $0.556 $0.627 $0.698 $0.769 $0.8310 $0.90We need to find an expression that can be used to find the cost of an n-minute long-distance call, where n is at least 5 minutes.

The cost of making a long-distance call is given for 5 minutes, 6 minutes, 7 minutes, 8 minutes, 9 minutes, and 10 minutes.

We can observe from the above table that for every increase of 1 minute, the cost increases by $0.07.

We can conclude that the cost of n minutes long-distance call is given by: (0.55 + (n - 5) x 0.07) dollars when n is at least 5 minutes.

Therefore, the required expression is: (0.55 + (n - 5) x 0.07) dollars when n is at least 5 minutes. The above expression is based on the pattern in the table provided for long-distance call rates. We can use this expression for values of n greater than or equal to 5.

A player of a video game is confronted with a series of opponents and has an 80% probability of defeating each one. Success with any opponent is independent of previous encounters. Until defeated, the player continues to context opponents. 1). What is the probability that a player defeats at least three opponents in a game

Answers

Answer:

0.512 = 51.2% probability that a player defeats at least three opponents in a game

Step-by-step explanation:

Outcomes in which he defeats less than three opponents:

Lose to the first opponent: 0.2 probability.

Beats the first opponent, loses to the second: 0.8*0.2 probability

Beats the first two opponents, loses to the third: 0.8*0.8*0.2 probability:

Probability of losing before beating three opponents:

[tex]P(b < 3) = 0.2 + 0.8*0.2 + 0.8*0.8*0.2 = 0.488[/tex]

What is the probability that a player defeats at least three opponents in a game?

[tex]P(b \geq 3) = 1 - p(b < 3) = 1 - 0.488 = 0.512[/tex]

Given the definitions of f(x) and g(x) below, find the value of (g o f) (-3)
f(x)=2x^2+6x+9
g(x)=3x-6

Answers

Answer:

21

Step-by-step explanation:

(g o f) (-3) = g ( f(-3) )

First, let's find f(-3):

f(x)=2x²+6x+9

f(-3)=2(-3²)+6(-3)+9

f(-3)=18-18+9

f(-3)=9

Now that we know the value of f(-3), we can sub this into g(f(-3)):

g ( f(-3) ) = g(9)

Find g(9):

g(9)=3x-6

g(9)=3(9)-6

g(9)=27-6

g(9)=21

Inverse functions

The point of an inverse function is that it gives the input value that results in the output value of the function it is the inverse of.

If f(x) has output value y, then its inverse function h(x) will give you ...

  h(y) = x

That is, h(f(x)) = x.
