Is this true? And also how does the equation from y-3=3(x-4) become a positive <br> y+3=3x-12?
EastWind [94]

Step-by-step explanation:

the right equation is :

y-y1=m(x-x1)

y+3=3(x+4)

y+3= 3x+12

y=3x+12-3

y=3x+9

In a coffee shop "Scratch and Win" contest, one out of three cards is a winner. What is the probability that Shenice would first
jolli1 [7]

Answer: C.) 4/27

Step-by-step explanation:

Given that:

One out of three cards is a winner :

P(winning) = 1 / 3

Therefore, P(not winning) = P(losing) :

1 - P(winning) = 1 - 1/3 = 2/3

Probability that shenice will first win on her third try can be interpreted as:

1st try = lose, 2nd try: lose, 3rd try : win

P(losing) × p(losing) × p(winning)

(2/3) × (2/3) × (1/3)

4 / 27

Probability of first winning on third try = 4/27

Solve the equation on the interval [0,2π). cos^4x=cos^4xcscx
Alisiya [41]
\bf cos^4(x)=cos^4(x)csc(x)\\\\&#10;-----------------------------\\\\&#10;cos^4(x)=cos^4(x)\cfrac{1}{sin(x)}\implies cos^4(x)=\cfrac{cos^4(x)}{sin(x)}&#10;\\\\\\&#10;cos^4(x)sin(x)=cos^4(x)\implies cos^4(x)sin(x)-cos^4(x)=0&#10;\\\\\\&#10;cos^4(x)[sin(x)-1]=0\to &#10;\begin{cases}&#10;cos^4(x)=0\to x=cos^{-1}(0)\\&#10;----------\\&#10;sin(x)-1=0\\&#10;sin(x)=1\to x=sin^{-1}(1)&#10;\end{cases}

\bf \measuredangle x = cos^{-1}(0)\implies \measuredangle x = &#10;\begin{cases}&#10;\frac{\pi }{2}\\\\&#10;\frac{3\pi }{2}&#10;\end{cases}&#10;\\\\\\&#10;\measuredangle x=sin^{-1}(1)\implies \measuredangle x=\frac{\pi }{2}

Bronson builds a rectangular deck for his friend. the width of the deck is 29 feet. the perimeter of the deck must be at least 1
olga_2 [115]
<span>Answer: a) Greater than or equal to 38 feet b)Since there is no restriction on the perimeter there exists many possible values for the length of the deck. Explanation: Given that the width of the deck is 29 ft. and the perimeter of the deck is at least 134 ft. 134 = 2(length + width) 134 = (2 x length) + (2 x 29) 134 = (2 x length) + 58 2 x length = 134 - 58 2 x length = 76 length = 76 / 2 length = 38 ft Thus, the inequality will be: a)Length ≥ 38 ft b)since there is no restriction on the perimeter there exists many possible values for length of deck.</span>
