Step-by-step explanation:
If first expression multiples 3 so: -6x-9y=-48 to emerge with second expression
Answer:
|7000 - w| < 1000
Step-by-step explanation:
6000 < w < 8000
Subtract 7000 from the three "sides."
-1000 < w - 7000 < 1000
|w - 7000| < 1000
|7000 - w| < 1000
Answer:
x= -(d-a)/(b+c)
Step-by-step explanation:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero
Answer:
In a decimal it would be 177.577
In a fraction it would be 177 577/1000
The question involves the concept & equations associated with projectile motion.
Given:
y₁ = 1130 ft
v₁ = +46 ft/s (note positive sign indicates upwards direction)
t = 6.0 s
g = acceleration due to gravity (assumed constant for simplicity) = -32.2 ft/s²
Of the possible equations of motion, the one we'll find useful is:
y₂ = y₁ + v₁t + 1/2gt²
We can just plug and chug to define the equation of motion:
<u><em>y = (1130 ft) + (46 ft/s)t + 1/2(-32.2 ft/s²)t²</em></u>
<em>(note: if you were to calculate y using t = 6.0 s, you'd find that y = 826.4 ft, instead of 830 ft exactly because of some rounding of g and/or the initial velocity)</em>
