A power lifter is leg-pressing 720 pounds on a leg press machine. The angle of the press is 60 degrees. What is the actual weigh
Triss [41]

Since, the angle between the machine and angle of press is 60^{\circ} as shown in the attached image.

Therefore, the actual weight lifted by the power lifter is given by w \times \cos \Theta

where 'w' stands for the weight being lifted and \Theta is the angle of press.

Now,

actual weight lifted by the power lifter = 720 \times \cos 60^{\circ}

= 720 \times \frac{1}{2} = 360 pounds.

Hello i need help with these questions asap!!
makvit [3.9K]

We use direct proportionality:

360⁰......Pi×R² (full circle)

120⁰.......x

x=120×pi×R²/360=pi×R²/3

x=pi×4²/3=16.76mi²

A=3×pi cm², for an angle of 2×pi/3=120⁰

In a similar way we compute the area of the full circle:

360.........x

120..........3×pi

x=3×pi×360/120=9×pi=3²×pi.

Thus the radius is 3cm.

Answer:

The function f(x)= \frac{1}{x^2+2} is continuous for all real numbers

Step-by-step explanation:

To know the possible points of discontinuity of this function, we must find out when the denominator of the function is equal to 0.

The denominator is:

x ^ 2 + 2

Then we equal 0 and clear x

x ^ 2 +2 = 0\\\\x ^ 2 = -2

x ^ 2> 0 for any real number.

This means that

x ^ 2 +2> 0 <em>for all reals numbers</em>.

Therefore, the function f(x)= \frac{1}{x^2+2} is <em>continuous</em> for all real numbers, that is, it does not have discontinuities.

The graphic of this function is shown in the image
