A counterexample for the expression sin y tan y= cos y is 0.

umka21 [38]

Answer:

True

Step-by-step explanation:

To answer this question we must evaluate

y = 0° on both sides of the equation.

For the left side we have:

$sin(0\°) tan(0\°)$

We know that $tan(0\°) =\frac{sin(0\°)}{cos(0\°)}$

We know that $cos(0\°) = 1$ and $sin(0\°) = 0$ .

Therefore $tan(0\°) = 0$ .

Then the left-hand side of the equals is equal to zero.

On the right side we have:

$cos(y)$

When evaluating $cos(y)$ at $y = 0$

We have to $cos(0\°) = 1$ .

0 ≠ 1

The equation is not satisfied. Therefore y = 0 ° is a counterexample to the equation

Complete the table of inputs and outputs for the given function. g(x)=-4x-1

Radda [10]

Answer:

(x, y) = (-2, 7), (0, -1), (3, -13), (-1, 3)

Step-by-step explanation:

To fill in the y-values, you need to put the x-value in the equation and evaluate.

for x=0

y = -4(0) -1 = -1

for x=-1

y = -4(-1) -1 = 4 -1 = 3

To fill in the x-values, we can solve for x and then do as we did above.

y = -4x -1

y +1 = -4x . . . . add 1

-(y +1)/4 = x . . . divide by -4

for y=7

x = -(7 +1)/4 = -2

for y=-13

x = -(-13+1)/4 = -(-12/4) = 3

Then the table is ...

$\boxed{\begin{array}{cc}x&g(x)\\-2&7\\0&-1\\3&-13\\-1&3\end{array}}$
