Answer:

B is the correct choice.

Explanation:

r = 4sin∅, a = 4, R = 2

$\begin{tabular}{c | l}\theta & r \\ \cline{1-2}\pi /6 & 2\\\pi /3 & 2\sqrt{3}\\\pi /2 & 4\\2\pi /3 & 2\sqrt{3} \\5\pi /6 & 2\\\pi & 0\end{tabular}$

Plot these points.

In a computer catalog, a computer monitor is listed as being 19 inches.This distance is the diagonal distance across the screen.

KATRIN_1 [288]

Let's use the Pythagorean Theorem to solve this.

One side is 10 inches, the other side we don't know, and the hypotenuse is 19 inches. We will call the side we don't know <em>x</em>.

Thus, $10^2 + x^2 = 19^2$
$x = \sqrt{19^2 - 10^2} = \sqrt{261} = \boxed{3\sqrt{29}}$

Please help me with this ACT Prep problem.

Answer:

Option C

Step-by-step explanation:

ΔABC and ΔDEF are similar triangles.

By the property of similar triangles, corresponding sides of the similar triangle are proportional.

$\frac{AB}{DE}=\frac{BC}{EF}=\frac{AC}{DF}$

$\frac{6}{DE}=\frac{6}{3}=\frac{10}{5}$

$\frac{6}{DE}=\frac{6}{3}$

DE = 3

Perimeter of ΔDEF = Sum of measures of the sides of the triangle

= DE + EF + DF

= 3 + 3 + 5

= 11

Therefore, Option C will be the correct option.

We’re learning polynomial functions and I have absolutely no idea how to do it. The first question is “State the degree and lead

ycow [4]

Let's begin by defining the key terminologies:

The degree of a polynomial simply refers to the term with the highest exponent in a polynomial

For example:

$\begin{gathered} a+8\Rightarrow a^1+8 \\ =a^1+8 \\ \text{We will observe that the variable ''a'' has a degree of ''1''} \\ \text{Therefore, the degree of this polynomial will be ''1''} \\ \\ \text{If we have}\colon5a^2+10 \\ 5a^2+10 \\ \text{We will observe that the variable ''a'' has the highest degree of ''2''} \\ \text{Therefore, the degree of this polynomial will be ''2''} \\ \\ \text{If we have}\colon3a^4+2a^2+10a+10 \\ 3a^4+2a^2+10a+10 \\ \text{We will observe that the variable ''a'' has the highest degree of ''4'' } \\ \text{Therefore, the degree of this polynomial will be ''4''} \end{gathered}$

The leading coefficient simply refers to the coefficient of the term that has the highest degree in a polynomial

For example:

$\begin{gathered} \text{If we have}\colon a+8 \\ a+8 \\ \text{''a'' is the variable having the highest degree, that degree is ''1''} \\ \text{The coefficient of the variable ''a'' is 1. Hence, the leading coefficient is ''1''} \\ \\ \text{If we have}\colon5a^2+10 \\ 5a^2+10 \\ \text{''}5a^2\text{'' is the variable with the highest degree},\text{ that is ''2''} \\ \text{The coefficient of the variable ''}5a^2\text{'' is 5. Hence, the leading coefficient is ''5''} \\ \\ \text{If we have}\colon3a^4+2a^2+10a+10 \\ 3a^4+2a^2+10a+10 \\ \text{ ''}3a^4\text{'' is the variable with the highest degree},\text{ that is ''4''} \\ \text{The coefficient of the variable ''}3a^4\text{'' is ''3''. Hence, the leading coefficient is ''3''} \end{gathered}$
