Luther and Martin are members of different video game libraries.

kogti [31]

In this case you actually don't have to do much of any work. The 6x means Martin pays six dollars per game. That means the additional 60 is his membership fee. Luthers function would look like this: y= 9x+85 which 85 is the fee and he pays nine dollars per game. Subtract the fees and you get that Luther pays $15 more for the membership.

During a fireworks show, a rocket is fired vertically upward with an initial velocity of 200 meters per second. The height in me

My name is Ann [436]

Answer:

<h2>The rocket can safely explode in 10 ≤ t ≤ 30 seconds (see the last line of explanation).</h2>

Step-by-step explanation:

The height of the rocket is shown by $s = 200t - 5t^{2}$ , where t is the time in seconds.

$\frac{ds}{dt} = 200 - 10t$ . The height will be maximum when, $\frac{ds}{dt} = 0$ that is $t = \frac{200}{10} = 20$ .

At t = 20, s = 4000 - 2000 = 2000.

The rocket can go 2000 meter maximum.

In order to explode safely, the rocket must be in a height equal or above 1500 meter.

When s = 1500, $1500 = 200t - 5t^{2} \\t^{2} - 40t + 300 = 0\\t^{2} - 30t - 10t + 300 = 0\\t = 30,10.$

Hence, at $10 \leq t \leq 30$ , the height $s \geq 1500$ .

Point D is the incenter of triangle BCA. If m∠FDG = 136°, what is the measure of ∠FHG?

nikdorinn [45]

Given:

Point D is incenter of ΔBCA.

m∠FDG = 136°

To find:

The measure of ∠FHG

Solution:

<em>Angle subtended by the arc at the center is twice that subtended on the remain part of the circle.</em>

$\Rightarrow m\angle FDG = 2 m\angle FHG$

Divided by 2 on both sides.

$$\Rightarrow \frac{1}{2} m\angle FDG = \frac{1}{2} \times 2 m\angle FHG$

$$\Rightarrow \frac{1}{2} m\angle FDG = m\angle FHG$

Substitute m∠FDG = 136°

$$\Rightarrow \frac{1}{2} (136^\circ)= m\angle FHG$

$$\Rightarrow 68^\circ= m\angle FHG$

The measure of ∠FHG is 68°.
