Answer:

M=-2

Step-by-step explanation:

3m+2−1/4m=1/2(m−5)

Step 1: Simplify both sides of the equation.

3m+2−1/4m=1/2(m−5)

3m+2+−1/4m=(1/2)(m)+(1/2)(−5)(Distribute)

3m+2+−1/4m=1/2m+−5/2

(3m+−1/4m)+(2)=1/2m+−5/2

(Combine Like Terms)

11/4m+2=1/2m+−5/2

11/4m+2=1/2m+−5/2

Step 2: Subtract 1/2m from both sides.

11/4m+2−1/2m=1/2m+-5/2−1/2m

9/4m+2=−5/2

Step 3: Subtract 2 from both sides.

9/4m+2−2=−5/2−2

9/4m=−9/2

Step 4: Multiply both sides by 4/9.

(4/9)*(9/4m)=(4/9)*(−9/2)

m=−2

Answer:

m=−2

Find the minimum and maximum value of the function on the given interval by comparing values at the critical points and endpoint
Kitty [74]

Answer:

maximum: y = 1

minimum: y = 0.

Step-by-step explanation:

Here we have the function:

y = f(x) =  √(1 + x^2 - 2x)

we want to find the minimum and maximum in the segment [0, 1]

First, we evaluate in the endpoints, which are 0 and 1.

f(0)  =√(1 + 0^2 - 2*0) = 1

f(1) = √(1 + 1^2 - 2*1) = 0

Now let's look at the critical points (the zeros of the first derivate)

To derivate our function, we can use the chain rule:

f(x) = h(g(x))

then

f'(x) = h'(g(x))*g(x)

Here we can define:

h(x) = √x

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

Then:

f(x) = h(g(x))

f'(x)  =  1/2*( 1 + x^2 - 2x)*(2x - 2)

f'(x) = (1 + x^2 - 2x)*(x - 1)

f'(x) = x^3 - 3x^2 + x - 1

this function does not have any zero in the segment [0, 1] (you can look it in the image below)

Thus, the function does not have critical points in the segment.

Then the maximum and minimum are given by the endpoints.

The maximum is 1 (when x = 0)

the minimum is 0 (when x = 1)

Estimate the perimeter of the figure to the nearest whole number.
ser-zykov [4K]

Answer:

See Explanation Below

Step-by-step explanation:

The question is incomplete (because the figure to calculate the perimeter is missing).

However from the comment attached to your question, I understand that the figure looks like a plus sign.

The perimeter of a plane shape is calculated by adding the length of each side of the shape.

Take for instance;

A square of length 5cm.

We know that a square has 4 equal sides; meaning that the length of the other sides are also 5cm

So, the perimeter of the square will be calculated as 5cm + 5cm + 5cm + 5cm = 20cm

Similarly, the perimeter of a triangle whose sides are 4ft, 3ft and 5ft will be calculated by adding up the length of the three sides.

Perimeter of the triangle = 4ft + 3ft + 5ft

Perimeter = 12ft.

Having explained how the perimeter of a plane shape is calculated; take for example, the attachment below.

(The sides are measured in centimetres)

The plus sign has 12 sides; Its perimeter is calculated by adding up the length of the 12 sides.

Perimeter = 3 + 7 + 7 + 5 + 5 + 5 + 5 + 2 + 2 + 4 + 4 + 3

Perimeter = 52cm
