Factor the expression.<br> 10x + 25<br> (Factor completely.)

Luda [366]

Answer:

5(2x+5)

Step-by-step explanation:

This is the answer because the highest multiple is 5 for both of them.

so since it is 5 divide both numbers by 5 put 5 outside the parenthisis and

then divide the numbers inside

this will give you - 5(2x+5)

Hope it helps :)

The displacement of a 500 g mass, undergoing simple harmonic motion, is defined by the function :

Valentin [98]

To solve this problem, we have to write out the simple harmonic motion equation and then use the respective formula to solve. The maximum kinetic energy, maximum potential energy and the maximum mechanical energy is equal to 7.56J.

<h3>Simple Harmonic Motion</h3>

The given equation of the simple harmonic motion is

$x = 3.5sin(\frac{\pi}{2t} + \frac{5\pi}{4})\\$

Data;

ω = π/2
k = 1.254N/m

Solving this

$\frac{dx}{dt} = \theta = -3.5 * \frac{\pi}{2} cos (\frac{\pi }{2}t + \frac{5\pi}{4})\\$

Let's calculate the maximum velocity.

$V_m = \frac{3.5\pi}{2}$

This is only possible when cos θ = -1

The maximum kinetic energy is

$K_m = \frac{1}{2}mv_m^2 = \frac{1}{2}* \frac{500}{1000} * (\frac{7\pi}{4} )^2\\K_m = 7.56J$

The maximum kinetic energy is 7.56J

The maximum potential energy can be calculated as

$\omega^2 = \frac{k}{m} \\k = \omega^2 m \\k = \frac{\pi^2}{4} * \frac{500}{1000}\\ k= 1.254 N/m$

Using the value of spring constant, we can find the maximum potential energy

$P.E = \frac{1}{2}kx^2\\P.E = \frac{1}{2} * 1.234 * 3.5^2\\P.E = 7.56J$

The maximum potential energy is 7.56J

The maximum mechanical energy is equal to the sum of maximum potential energy and the maximum kinetic energy.

$ME = P.E + K.E\\ME = 7.56J$

The reason ME is equal to 7.56J is because when x is at maximum, v = 0 and makes kinetic energy equal to zero.

ME = 7.56J

From the calculations above, the maximum kinetic energy, maximum potential energy and the maximum mechanical energy is equal to 7.56J.

A school is painting its logo in the shape of a triangle in the middle of its sports field. The school wants the height of the t

Radda [10]

Answer:

$b\geq 9$

In other words, the base must be at least 9 feet long.

Step-by-step explanation:

The schools wants the height of the triangle to be eight feet, and the area of the logo to be at least 36 square feet.

Recall that the area of a triangle is given by:

$\displaystyle A = \frac{1}{2}bh$

Since we want to area to be at least 36 square feet:

$\displaystyle \frac{1}{2}bh \geq 36$

We are given that the height is eight feet. Substitute:

$\displaystyle \frac{1}{2}(8)b\geq 36$

Simplify:

$4b\geq 36$

Divide both sides by four. Hence, our inequality is:

$b\geq 9$

In words, this means that the base must be at least 9 feet long.
