The question is about unit circle in screenshot
Orlov [11]

The complete sentence for the <em>unit</em> circle is:

<em>When t = 0, AP = 0, so sin t will begin at a value of 0. As t increases from 0 to π/2, sin t increases. Eventually, when t = π/2, OP will be 0, so sin t = AP will be 1.</em>

<h3>How to complete a sentence with concepts from trigonometry</h3>

In this problem we have sentence to be completed by direct observation to the variables seen in a unit circle, a form used to teach trigonometric functions in a <em>graphic</em> manner. Now we proceed to present the complete sentence below:

<em>When t = 0, AP = 0, so sin t will begin at a value of 0. As t increases from 0 to π/2, sin t increases. Eventually, when t = π/2, OP will be 0, so sin t = AP will be 1.</em>

Question 12 Multiple Choice Worth 1 points)(07.05 MC)1086Which of the following functions best represents the graph?fix)=(x-2)(x
vlada-n [284]

The graph of a function is given. It is required to find the function that represents the graph.

Notice from the graph that the function has roots or zeros at -3,-2, and 2.

Hence, the function takes the form:

\begin{gathered} f(x)=a(x-(-3))(x-(-2))(x-2) \\ \Rightarrow f(x)=a(x+3)(x+2)(x-2) \end{gathered}

Where a is a constant to be determined.

Notice that the given graph passes through the point (0,-12).

Substitute x=0 and f(x)=-12 into the equation of the function to find a:

\begin{gathered} -12=a(0+3)(0+2)(0-2) \\ \Rightarrow-12=a(3)(2)(-2) \\ \Rightarrow-12=-12a \\ \text{ Swap the sides of the equation:} \\ \Rightarrow-12a=-12 \\ \text{ Divide both sides by }-12: \\ \Rightarrow\frac{-12a}{-12}=\frac{-12}{-12} \\ \Rightarrow a=1 \end{gathered}

Hence, the function is:

\begin{gathered} f(x)=1(x+3)(x+2)(x-2) \\ \Rightarrow f(x)=(x+2)(x+3)(x-2) \end{gathered}<h2>The third option is the answer: f(x)=(x+2)(x+3)(x-2).</h2>

Log 10(x + 3) – log 10(x-3) = 1
nadezda [96]

Answer:33/9

Step-by-step explanation:

Log10(x+3)-Log10(x-3)=1

Log10((x+3)/(x-3))=1

(x+3)/(x-3)=10^1

(x+3)/(x-3)=10

Cross multiply

x+3=10(x-3)

Open brackets

x+3=10x-30

Collect like terms

10x-x=30+3

9x=33

Divide both sides by 9

9x/9=33/9

x=33/9

Find p(0),p(1),p(-1) and p(2) of the 3x(x-2) <br><br>​
Effectus [21]

Answer:

<u>make x→0</u>

p(0)=(0)^{2}-3(0)+2

→ p(0)=0+0+2

→p(0)=2

------

<u>Replace x→-1</u>

p(-1)=(-1) ^{2} -3 (-1)+2

→ p(-1)=1-3+2

→ p(-1)=0

----------

<u>Now make x→2</u>

p(2)=(2) ^{2} -3(2)+2

→ p(2)=4-6+2

→ p(2)=0

Answer:-2,0,0

-----------

hope it helps...

Find cp if so =rs 800 and loss% = 10%​
rjkz [21]

Step-by-step explanation:

Sp = rs 800

loss = 10%

Cp = ?

we know that,

cp= sp×100÷ 100-L%

= 800×100÷100-10

= 80000÷90

= 888.89#
