Which is a solution to the equation |10-5y|=20<br><br>y=2<br><br>y=4<br><br>y=6<br><br>y=10
Pavlova-9 [17]

Answer:

y=6

Step-by-step explanation:

|10-5y|=20

Since the absolute value is isolated, we can then separate the equations

For absolute values, there is a positive and negative when we remove the absolute values.

10-5y = 20          10-5y= -20

Subtract 10 from each side

10-10-5y = 20-10          10-10-5y= -20-10

-5y = 10                             -5y = -30

Divide by -5

-5y/-5 =10/-5                    -5y = -30/-5

y =-2                                      y =6

A ball is thrown from an initial height of 2 meters with an initial upward velocity of 15/ms . The ball's height h (in meters) a
Irina-Kira [14]
The height that a ball reaches at a certain time t is given by the equation,
           h = 2 - 15t + 5t²
We are asked to compute for the values of t that would allow the ball to reach a height of 7 meters. 

Substitute the 7 to the equation,
         7 = 2 - 15t + 5t²
Transposing,
               5t² - 15t - 7 + 2 = 0
Simplifying,
               5t² - 15t - 5 = 0
Divide the equation by 5,
               t² - 3t - 1 = 0

The values of t can be calculated through the quadratic formula,
             t = (-b +/- sqrt(b² - 4ac))/2a

Substituting, 
             t = (3 +/-sqrt (9 - 4(-1)) / 2(1)
              t = 3.3 or t = -0.30

Since, we cannot have t as a negative number hence, our final answer is:
      <em> t = 3.3 s</em>

Please help, very confused!
My name is Ann [436]
\bf cot(\theta)=\cfrac{1}{tan(\theta)}&#10;\qquad \qquad &#10;csc(\theta)=\cfrac{1}{sin(\theta)}\qquad \qquad sin(-\theta )=-sin(\theta )&#10;\\\\\\&#10;\textit{also recall }sin^2(\theta)+cos^2(\theta)=1\implies sin^2(\theta)=1-cos^2(\theta)\\\\&#10;-------------------------------

\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)}&#10;\\\\\\&#10;\cfrac{\frac{sin^2(x)}{sin^2(x)}}{-cos(x)}\implies \cfrac{1}{-cos(x)}\implies -sec(x)
