Answer:
Hmax = 269.76 feet
Step-by-step explanation:
This movement is vertical shot up.
We will accept value of g= 10m/s², but we must convert meters in the feets.
We know that 1 meter = 3.28 feets => 10meters = 32.8 feets
According to this g= 32.8 feet/s²
A flare is launched upwards from the height platform H₁ = 20 feet.
Initial velocity is 128 feet per second, when the flare reaches the highest point the final velocity is zero.
We will marked velocity with V and use this formula
V₀² - V² = 2 · g · H₂ and V= 0 => V₀² = 2 · g · H₂ => H₂ = V₀²/ 2 · g
H₂ = 128² / 2 · 32.8 = 16384 / 65.6 = 249.76 feet
The highest point in feet , that the flare reaches is:
Hmax = H₁ + H₂ = 20 + 249.6 = 269.6 feet.

Answer:

Step-by-step explanation:
<u>Vertex form of a quadratic equation</u>:

where:
- (h, k) is the vertex
- a is some constant
<u>Given vertex</u>: (2, -6)
⇒ h = 2 and k = -6
Substitute the values of h and k into the formula:


As we have not been given a value for the constant
, assume this is 1.
Therefore, the <u>vertex form</u> of the <u>quadratic function</u> with vertex (2, -6) is:

Determine whether the relation is a function. {(−3,−6),(−2,−4),(−1,−2),(0,0),(1,2),(2,4),(3,6)}
Semmy [17]
Answer:
Yes, this is a function
Step-by-step explanation:
This relation is function because 1 x value corresponds to 1 y value
1 1/2 miles is the same as walking 1/2 a mile 3 times, so we can divide 22.5 minutes by 3 to find how long it takes to walk half a mile
22.5/3=7.5
We can then multiply 7.5 by 2 to get how long it takes to walk 1 mile
7.5 x 2 = 15 minutes
It takes Avante 15 minutes to walk 1 mile
