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.
God with you!!!
3x+1=-14
x=-5
Subtract 1 from both sides.
3x=-15
Finally, divide both sides by 3 to get rid of 3x.
x=-5
Therefore, we have proved that x=-5.

Answer:
The conversion of 2 yards into centimeter is 183 centimeter .
Option (D) is correct .
Step-by-step explanation:
As given
1 yard = 3 feet
1 foot = 12 inches
1 inch = 2.54 cm
Take
1 inch = 2.54 cm
Mutiply above by 12.
1 × 12 inch = 2.54 × 12 cm
12 inch = 30.48 cm (As 1 foot = 12 inches )
Thus
1 foot = 30.48 cm
Multiply above by 3
1 × 3 foot = 30.48 × 3 cm
3 foot = 91.44 cm (As 1 yard = 3 feet )
1 yard = 91.44 cm
Thus the relationship between the yard and centimeter is given by.
1 yard = 91.44 cm
Now convert 2 yards to centimeters .
2 yards = 2 × 91.44 centimeters
= 182.88
= 183 centimeter (Approx)
Therefore the conversion of 2 yards into centimeter is 183 centimeter .
Option (D) is correct .
