Answer:
omg college math is so hard omg i feel baddddddd
Step-by-step explanation:
0.75(3.5a -6b)
= 0.75* (3.5a) -0.75* (6b) (distributive property)
= 2.625a -4.5b
The final answer is 2.625a -4.5b~
Answer:
C)
f(–3) = 9
Step-by-step explanation:
Given f(x) = 4x^4 + 5x^3 – 15x^2 – 45
f(-3) means let x = -3
f(-3) = 4(-3)^4 +5(-3)^3 – 15(-3)^2 – 45
=4(81) +5(-27) -15(9) -45
= 324 - 135 - 135 -45
=9
The statement “If the movement of a mass on a spring may be
modeled with simple harmonic motion, then its frequency decreases with time”
is false.
<span>In mechanics and physics, simple </span><span>harmonic motion </span>is a type of
periodic motion<span> or oscillation </span><span>motion </span>where the restoring force is directly proportional to
the displacement and acts in the direction opposite to that of displacement .
Answer:19.74 gallons of the gas in the tank is wasted.
Step-by-step explanation:
Since the efficiency of the gas engine is 6%, wastage is #= 100 - 6 = 94%.
Therefore wastage = 94% x 21=94 x21/100=19.74 gallons
