Can relative maximums and minimums be at the endpoints? I know global max/min can be at endpoints but I'm not sure about relativ

e max/min.

Answer:

No

Step-by-step explanation:

Just because the derivative is 0 at a point doesn't necessarily mean it is a relative minimum or maximum.  You must be able to evaluate the derivative on both sides of the point to determine if it changes signs.  Since endpoints have only one side, they cannot be relative maximums or minimums.

You draw the rectangle with verticals at (-3.5, 3), (3.5, 3), and (-3.5, -3). What is the perimeter and area of the rectangle?
natka813 [3]

We want to know the perimeter and area of a rectangle given that we know where the vertices are.

We will get:

perimeter = 26

area = 42

While you wrote verticals, you wrote points, then I assume that it should say vertices.

The vertices of the rectangle are:

(-3.5, 3), (3.5, 3), (-3.5, -3), and one missing but that is the final one, (3.5, -3).

Note that we have two x-values and two y-values, we can define the length as the difference in the x-values and the width as the difference in the y-values, then we will get:

length = 3.5 - (-3.5) = 7

width = 3 - (-3)  = 6

Now we know the length and width of the rectangle, the perimeter is:

P = 2*(6 + 7) = 26

The area is:

A = 6*7 = 42

Given the following triangle, if c = 23.5 and m B = 51°, find a to the nearest whole number
klasskru [66]

Answer:

A. 15

Step-by-step explanation:

We are given a right angles triangle with hypotenuse length (c) = 23.5 and ∠B = 51°.

Now, using the trigonometric forms of a right angled triangle, we get,

\cos51=\frac{adjacent}{hypotenuse}

i.e. \cos51=\frac{a}{c}

i.e. 0.6293=\frac{a}{23.5}

i.e. a=0.6293 \times 23.5

i.e. a=14.8

So, the value of a = 14.8.

Hence, the nearest whole number to 14.8 is 15 i.e. a = 15.
