I am having trouble with these questions here. ​

Mathematics
1 answer:
Andre45 [30]3 years ago
5 0

Explanation:

1. The Pythagorean theorem has nothing to do with the values of angles. It cannot be used to find the values of angles, special or otherwise.

__

2. Transformations affect the graphs of trig functions the same way they affect the graphs of any other functions. Transformations can be used to shift and scale (and rotate) the sine and cosine functions in the same way that any functions or collections of points can be shifted, scaled, or rotated.

__

3. The coordinates of a point on the unit circle relate directly to the cosine and sine of the angle from the x-axis to that point (see attached). The remaining four trig functions are defined in terms of these:

  tan = sin/cos

  cot = cos/sin

  sec = 1/cos

  csc = 1/sin

What is the decimal expansion for 14 over 33?
AveGali [126]

Hi! I believe your answer is 0.42, (simplified form of 0.42424242424) which is 14/33 (or \frac{14}{33} ) as a decimal. I hope this helps you! Good luck and have a great day. ❤️✨

Question in image. Thanks!
boyakko [2]

Answer:

B (i do also slightly lean towards C, but i'm pretty sure it would be B because it gives a specific measurement)

Step-by-step explanation:

If all angles that are either adjacent or opposite are supplementary, all angles must be 90°

If at all times adjacent sides are 5 inches, all sides are equal.

Knowing this, it has to be a square because all angles would be 90° and all sides would be equal.

F(x)=x-3<br> g(x)=-0.5x<br> for what interval is the value of (f-g)(x) negative?
yarga [219]

Answer:

(-∞, 2)

Step-by-step explanation:

<u>Given functions</u>:

\begin{cases} f(x)=x-3\\g(x)=-0.5x \end{cases}

Function composition is an operation that takes two functions and produces a third function.

The <u>composite function</u> (f - g)(x) means to subtract function g(x) from function f(x):

\begin{aligned}(f-g)(x) & = f(x)-g(x)\\& = (x-3)-(-0.5x)\\& = x-3+0.5x\\& = 1.5x-3\end{aligned}

To find the interval for which (f - g)(x) is negative, set the new function to <u>less than zero</u> and solve the <u>inequality</u>:

\begin{aligned}(f-g)(x) & < 0\\\implies 1.5x-3 & < 0\\1.5x & < 3\\x & < \dfrac{3}{1.5}\\x & < 2\end{aligned}

Therefore, the interval for which (f - g)(x) is negative is (-∞, 2).

An atom is neutral. Its nucleus contains two protons and two neutrons. How
KIM [24]

Answer:

2 electrons

Step-by-step explanation:

An atom is neutral if it has no charge. That means the positive and negative charge balance each other out.

There are two protons, so that is a charge of +2. To make the charge 0, there needs to be a charge of -2. -2= 2 electrons.
