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.

If h(x) is the inverse of f(x), what is the value of h(f(x))?
0
1
X
f(x)
Answer:
(c) x
Step-by-step explanation:
You want to know the value of h(f(x)) if h(x) is the inverse of f(x).
Inverse functionsThe 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.
<95141404393>
Answer:
If h(x) is the inverse of f(x), then by definition, h(f(x)) would yield the value of x. In other words, h(f(x)) = x.

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
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

Please answer the following question on linear algebra.
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.

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.
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.

Answer:
a = 15yd is the answer.
Step-by-step explanation:
a = ?
b = 8yd
c = 17yd
By using the Pythagoras theorem,
a² + b² = c²
a² + 8² = 17²
a² + 64 = 289
a² = 289 - 64
a² = 225
a = 15
∴ a = 15yd is the length of the missing leg.
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
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]
0.512 = 51.2% probability that a player defeats at least three opponents in a game
