Answer:
d
Step-by-step explanation:
5x + 4 = -6
5x= -6-4
5x=-10
x=-2
The value of the first expression is x=-2.
x/2 + 3 = 2
x/2 = 2-3
x/2 = -1
x=-2
The value of the second expression is x=-2.
2x+14=10
2x=-4
x=-2
The value of the third expression is x=-2.
-2=-x
2=x
The value of the fourth expression is x=2.
Answer:
Step-by-step explanation:
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>
the blue dotted line means the parent function was shifted 2 units down
so the graph is g(x) = (1/3)^x-2
Answer would be A.
