Over what interval will the immediate value theorem apply
koban [17]

Answer:

Any [a,b] that does NOT include the x-value 3 in it.

Either an [a,b] entirely to the left of 3, or

an  [a,b] entirely to the right of 3

Step-by-step explanation:

The intermediate value theorem requires for the function for which the intermediate value is calculated, to be continuous in a closed interval [a,b]. Therefore, for the graph of the function shown in your problem, the intermediate value theorem will apply as long as the interval [a,b] does NOT contain "3", which is the x-value where the function shows a discontinuity.

Then any [a,b] entirely to the left of 3 (that is any [a,b] where b < 3; or on the other hand any [a,b] completely to the right of 3 (that is any [a,b} where a > 3, will be fine for the intermediate value theorem to apply.

What is the value of x?
Olin [163]

Answer:

An x-coordinate is the x value in an ordered pair, which is just two mathematical objects, such as numbers, paired together. ... For instance, in the ordered pair (2,5), the x-coordinate would be '2. ' This value tells you how far a point is from the origin, or starting point, in the x direction on a 2-dimensional graph.

How do you rearrange the equation (2x) /(4pi) +((1-x) /2) =0 to solve for x?
USPshnik [31]
\frac{2x}{4 \pi } + \frac{1-x}{2} =0 \\ &#10; \frac{x}{2 \pi } + \frac{1-x}{2} = 0
Then we will multiply both sides of the equation by 2 π :
x + π ( 1 - x ) = 0
x + π - π x = 0
x ( 1 - π ) = - π    / · ( - 1 )
x ( π - 1 ) = π
x = π / ( π - 1 )

Help pls!!
hodyreva [135]

Answer:

C) 33 meters

Step-by-step explanation:

In this question, we need to find the value of the variable "x".

To do this, we must use the Pythagorean theorem: a² + b² = c²

Plug in your values and solve:

56² + b² = 65²

3,136 + b² = 65²

3,136 + b² = 4,225

Subtract 3,136 from both sides.

b² = 1,089

To cancel out the exponent, we would square root both sides.

√b² = √1,089

b = 33

This means that C) 33 meters will be your answer.
