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

What is the 15th term of the sequence A(n) = 50 - 3(n-1) ?
Alexus [3.1K]

Answer:

A(15)=8

Step-by-step explanation:

Given that,

A(n)=50 - 3(n-1)

We need to find the 15th term of the sequence. Put n = 15 in the above sequence so that,

A(15)=50 - 3(15-1)\\\\A(15)=50-3(14)\\\\A(15)=50-42\\\\A(15)=8

So, the 15th term of the sequence is 8.
