Hello: here is a solution

You might be interested in

Please help, very confused!

My name is Ann [436]

$\bf cot(\theta)=\cfrac{1}{tan(\theta)}
\qquad \qquad 
csc(\theta)=\cfrac{1}{sin(\theta)}\qquad \qquad sin(-\theta )=-sin(\theta )
\\\\\\
\textit{also recall }sin^2(\theta)+cos^2(\theta)=1\implies sin^2(\theta)=1-cos^2(\theta)\\\\
-------------------------------$

$\bf \cfrac{csc^2(x)-cot^2(x)}{sin(-x)cot(x)}\implies \cfrac{\frac{1}{sin^2(x)}-\frac{cos^2(x)}{sin^2(x)}}{-sin(x)\frac{cos(x)}{sin(x)}}\implies \cfrac{\frac{1-cos^2(x)}{sin^2(x)}}{-cos(x)}
\\\\\\
\cfrac{\frac{sin^2(x)}{sin^2(x)}}{-cos(x)}\implies \cfrac{1}{-cos(x)}\implies -sec(x)$

To the nearest hundredth, what is the sine of the acute angle formed by the line whose equation is y = 3x - 3 and the positive x

Serhud [2]

Answer:

The sine of the acute angle is $0.95$

Step-by-step explanation:

using a graphing tool

see the attached figure

Let

A-----> the acute angle formed by the given line and the positive x-axis

In the right triangle XYZ

we know that

$sin(A)=\frac{xy}{xz}$

we have

$xy=3\ units$

$yz=1\ units$

Applying the Pythagoras Theorem find the value of xz

$xz^{2}=3^{2}+1^{2}\\ \\xz^{2}=10\\ \\xz=\sqrt{10}\ units$

substitute

$sin(A)=\frac{3}{\sqrt{10}}=0.95$

15 POINTS!!!! BRAINLIEST FOR THE FIRST ANSWER!!! Solve 3-x/2≤18

Bumek [7]

Answer:

$x\geq -30$

Step-by-step explanation:

Work to isolate x on one side of the inequality:

$3-\frac{x}{2} \leq 18\\3-18\leq \frac{x}{2} \\-15\leq \frac{x}{2}\\-30 \leq x$

Therefore the answer is all x values larger than or equal to -30

$x\geq -30$

If a penny is tossed five times, what is the probability of all tails? a zero b 1/16 c 1/32 d larger than the probability of all

amid [387]

Required probability = (1/2)^5 = 1/32

Its c (assuming that its a fair coin).
