Answer:
Step-by-step explanation:
The weight of an object on Moon is 6 times smaller than same on Earth.
<u>If it weights 18/5 kg on Earth then its weight on Moon is:</u>
Answer: C
<u>Step-by-step explanation:</u>
f(x) = 2x + 1 ⇒ 2x + 1
<u>- g(x) = -(x² - 7) </u>⇒ <u>-x² + 7 </u>
(f-g)(x) = -x² + 2x + 8
Answer:
70
Step-by-step explanation:
9/100=0.09
9-2.7=6.3
6.3/0.09=70
The angle is in the second quadrant so only the sine is positive .
Length of the hypotenuse = sqrt (-1^2 + 3^2) = sqrt10
sine = 1/sqrt10 = 0.3162 to 4 dec places
tangent = 1 / -3 = -0.3333 to 4 d p's
cosine = -3/sqrt10 = -0.9487 to 4 d, p's.
Step-by-step explanation:
Substitute in the known values of
r = 9 and θ =150 into the formulas. (9) cos (150)
y = (9) sin (150)
x = 9 (− cos (30) ) y = (9) sin (150)
The exact value of cos. (30) is <u>√3</u><u> </u>
2
x = 9 ( − <u>√3</u><u>)</u>
2
y = (9) sin (150)
blah blah blah
(9, 150) <em>is</em><em> </em>
