Tan(x)=sin(x)/cos(x) so
tan(pi/2)=1/0, which is undefined.

Answer:

tan(\frac{\pi}{2})=\frac{1}{0}

Step-by-step explanation:

The given expression is

tan(\frac{\pi}{2})

We know that the tangent function is defined as the quotient between the sin and cosin functions, that is

tan(\theta)=\frac{sin\theta}{cos \theta}, where \theta = \frac{\pi }{2}

So, if we use this trigonometric expression, we have

tan(\frac{\pi}{2})=\frac{sin(\frac{\pi}{2} )}{cos(\frac{\pi}{2}) }

But, \frac{\pi}{2}=90\° and cos90\°=0, sin90\° = 1

Replacing,

tan(\frac{\pi}{2})=\frac{1}{0}

Which is undetermined, because there is no number which product with zero isn't null.

Therefore, the solution is undetermined in this case.

F(x)= (x+2)^2 -1<br> Find x intercept <br> Find y intercept<br> Find vertex
Trava [24]
The x intercept occurs when y = 0.

0=(x+2)^2 - 1
1=(x+2)^2

Take the square root of both sides. Note that the sqrt of 1 is 1. Then solve for x.

1=x+2
-1=x

The x intercept is -1.

The y intercept occurs when x=0.

y=(0+2)^2 - 1
y=2^2 -1
y=4-1
y=3

The y intercept is 3.

Now, to find the vertex...

This parabola is currently in a format called the vertex form, which is:

f(x) = (x-h)^2 + k

where (h, k) is the vertex.

Therefore, the vertex is (-2, -1).

Evaluate the expression 21 ÷ 3 + 8 − 4.<br><br> A) 19<br><br> B) 17<br><br> C) 15<br><br> D) 11
nirvana33 [79]

Answer:

D

Step-by-step explanation:

We will use the order of operations to evaluate the expression.

From left to right , Multiplication/Division followed by Addition/Subtraction.

21 / 3 + 8 - 4

= 7 + 8 - 4

= 15 - 4

= 11

Therefore, the answer is D
