Answer: Answer is C.

Step-by-step explanation:

Let 65% of 90 be x

65% of 90 =x

65% of 90=x

65/100 x 90 =x

65/100 = x/90

so, 65/100 = x/90

I need help with this. I've tried to type out this problem, but it comes out wrong, so I uploaded a picture:
tatuchka [14]

answer: 6.4

work:

Solve the problem.

Let's start by solving the numerator,

(5 + 3)² <em>step one: add 5 + 3 </em>

(8)² <em>step two: simplify 8²</em>

64

now, let's simplify our denominator

1 + 2⁵ - 23 <em>step one: simplify 2⁵.</em>

1 + 32 - 23 <em>step two: add 1 + 32.</em>

33 - 23 <em>step three: subtract 33 - 23</em>

10.

now, put the numerator back over the denominator.

64/10

let's simplify by dividing, we get 6.4.

(sin x)(tan x cos x - cot x cos x) = 1 - 2 cos2x
Aliun [14]
As

\tan x=\dfrac{\sin x}{\cos x}
\cot x=\dfrac{\cos x}{\sin x}

we have

\sin x(\tan x\cos x-\cot x\cos x)=\sin x\left(\sin x-\dfrac{\cos^2x}{\sin x}\right)=\sin^2x-\cos^2x

Recalling that \cos2x=\cos^2x-\sin^2x, we end up with

-\cos2x=1-2\cos2x
1=\cos2x
\implies2x=2n\pi

(where n is any integer)

\implies x=n\pi

For a horizontal launch (θ0 = 0) at a fixed height ℎi &gt; 0, are the statements below correct? (Assuming friction can be ignore
Marizza181 [45]

Answer:

1) False. 2) True. 3) True. 4) False.

Step-by-step explanation:

1) False. The force of gravity will drive it down. The path will form a parabola.

2) True. There is no variation in the velocity in the horizontal axis and no force applied so the acceleration is zero.

3) True. The travel time depends on the height and the acceleration of gravity, and independent of the velocity of the rocket at launch.

4) False. The travel distance depends on the initial velocity of the rocket (at launch).
