The length of x to the nearest tenth is; D: 38.6 m

<h3>Trigonometric ratios</h3>

The image of the triangle is missing and so i have attached it.

From the image attached, we can find the value of x by using trigonometry ratio.

We see that;

  • AB = x
  • AC = 10
  • ∠BAC = 75°

Thus;

10/x = cos 75

10/x = 0.2588

x = 10/0.2588

x = 38.64 m

Approximating to the nearest tenth gives;

x = 38.6 m

A mouse runs along a baseboard in your house. The mouse's position as a function of time is given by x(t)=pt2+qt, with p = 0. 40
Gelneren [198K]

The  average speed between t = 1.0 s and t = 4.0 s will be 2.1+0.3 which is 2.4m/s

<h3>Velocity function </h3>

Given the equation for the position of the mouse expressed as:

x(t)=pt^2+qt\\

The velocity of the particle is expressed as:

v(t)=2pt+q

Given that p = 0. 40 m/s and q = -1. 10 m/s, the equation will become:

v(t)=2(0.4)t-1.10\\v(t)=0.8t - 1.10

If the time is <em>t = 1.0 s, the velocity will be:</em>

v(1) = 0.8 - 1.10\\v(1) = -0.3m/s

Similarly if t = 4.0ssec, hence:

v(4) = 3.2 - 1.10\\v(4) = 2.1m/s

The  average speed between t = 1.0 s and t = 4.0 s will be 2.1+0.3 which is 2.4m/s

What does the SAT reading test requires students to do?
Vlad1618 [11]

Answer:

When you take the Reading Test, you'll read passages and interpret informational graphics. Then you'll use what you've read to answer questions. Some questions ask you to locate a piece of information or an idea stated directly. But you'll also need to understand what the author's words imply.

2.3. Is the government doing enough to ensure that human rights are protected? Explain
umka2103 [35]
Well, it depends on what you mean by that. The constitution is clear that no matter your creed, race, religion, gender, wealth, or health, as long as you’re a United States citizen, you have the right to life, liberty, and the pursuit of happiness.

People have to realize that unfortunate things and tragedies will happen despite anything state or federal government does, so to take just one or two things and say the government isn’t doing enough is ridiculous.

I personally believe government should do more or less renovation, however what they’re doing at the moment is perfectly fine.
