Cos( 6 x ) = 1/2
6 x = 60° ⇒ x 1 = 10°
6 x = 300° ⇒ x 2 = 50°
6 x = 420° ⇒ x 3 = 70°
6 x = 660° ⇒ x 4 = 110°
x 5 = 130°, x 6 = 170°, x 7 = 190° , x 8 = 230°, x 9 = 250°,
x 10 = 290°, x 11 = 310°, x 12 = 350°
Answer: there are 12 solutions on the interval ( 0 , 2π ).
Answer:
MTD = 75
Step-by-step explanation:
RTD + RTM + MTD = 180
65 + 40 + MTD = 180
105 + MTD = 180
Subtract 105 from both sides.
MTD = 75

<span>The rocket that will reach a greater distance above the ground at its maximum height is y = -4x</span>² + 80x. The answer is letter B. This is because of the coefficient presented in the x² term. The number -4 is much greater than -6. Graphing these equations into a graphing paper or excel, you would get a parabola.
Answer:
D
Step-by-step explanation:
Because it's 340 meters per second
Answer:
√30
Step-by-step explanation:
We can find the value of x by using Euclidean theorem
x^2 = 3 × 10
if x^ = 30 then x = √30
