Suppose r(x) and t(x) are two functions with the same domain, and let h(x)=r(x)+t(x).

Suppose also that each of the 3 functions r, t and h, has a maximum value in this domain (i.e. a value that is greater than or equal to all the other values of the function).

Let M = the maximum value of r(x),
N = the maximum value of t(x), and
P = the maximum value of h(x).
How might the following always be true that M+N=P?

Prove the relationship to be true, or state what relationship does exist between the numbers M+N and P.

Answers

Answer 1

Answer:

If the maximum of function r(x) and t(x) occur at the same point c in domain P = max(r(x)+t(x)) = M+N

In general P  ≤  M+N

Step-by-step explanation:

If the maximum of function r(x) and t(x) occur at the same point c in domain then M=r(c) and N=t(c) So in this case P = max(r(x)+t(x)) = M+N

In general P  ≤  M+N

by definition of maximum  

r(x)≤M,t(x)≤N   for all x in domain

=>  r(x)+t(x)≤M+N   for all x in domain

=> max(r(x)+t(x)) <= M+N

=> P  ≤  M+N

Thus we get in general the relationship is P  ≤  M+N

Answers

Answer:

Area of his yard = 19680ft²

Fertilizer needed = 590.4 ounces

Step-by-step explanation:

Step 1 Find the area of his lawn

The question states that his lawn is a rectangle that measures 240 feet by 82 feet

To find the area of a rectangle we simply multiply the side lengths

Hence, area of his yard = 240 * 82 = 19680ft²

Step 2 find amount of fertilizer needed.

The question states that .03 ounces is used per square foot.

So to find the amount of fertilizer needed simply multiply total area by amount used per square foot.

19680 * .03 = 590.4

So we can conclude that John will need 590.4 ounces of fertilizer

I think it’s 590.4 because if you multiply 82 by 240 u get the square feet which is 19680 and then for every square foot you multiply by 0.03 to see how much fertilizer he uses for the lawn which is 540.4

what is the point-slope equation of a line with slope -5 that contains the point (6, 3)

Answers

Answer:

y - 3 = - 5(x - 6)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 5 and (a, b) = (6, 3) , then

y - 3 = - 5(x - 6)

Given :-

Slope = -5 Point = (6,3)

To Find :-

The point slope form of the line .

Solution :-

As we know that the point slope form of the line is ,

→ y - y1 = m ( x - x1 )

where (x1 , y1) is the point m is the slope .

→ y - 3 = -5( x - 6)

Hence the required answer is y - 3 = -5( x - 6 ) .

Answers

Answer:

Side c

Step-by-step explanation:

Generally triangles can be classified with respect to their sides, or their angles. And there is a relationship between the length of the sides and the measure of the opposite angles of a given triangle. The relationship is that; the longest length of side is the one that is always opposite to the greatest angle.

In the given question, the longest side given that m<A = 49°, m<B = 24°, and m<C = 107° of the internal angles of the triangle is side c. Since side c is opposite the greatest angle, <C.

Which of the following transformations
carry this regular polygon onto itself?

Answers

Each of the five lines of symmetry can be used to map the pentagon to itself in reflection.

Which transformation will carry a regular Pentagon onto itself?

A polygon can change without changing its shape when it undergoes a transformation. Examples include rotation, reflection, and translation. A figure's translation is a change in position that necessitates knowledge of both the direction and the distance. The picture is the final shape that emerges from a transformation.

Five lines of symmetry make up a regular pentagon. Each of the five lines of symmetry can be used to map the pentagon to itself in reflection. Rotate the point 144 degrees in order to convert (0, -2). As a result, the 144° transformation translates the standard pentagon with the coordinates (0, -2) onto itself.

Putting a point, line, or other shape on top of a line. A regular polygon needs to be reflected over a symmetry line in order to map onto itself.

Therefore, the correct answer is option c) Reflection across L.

Suppose that the dollar cost of producing x ratios is c(x)=800+40x-0.2x^2. Find the average cost per radio of producing the first 40 radios.

Answers

Answer:

24radios

Step-by-step explanation:

Given that the dollar cost of producing x ratios is c(x)=800+40x-0.2x^2. Find

Average cost is expressed as dC(x)/dx

dC(x)/dx = 40-0.4x

C'(x) = 40 - 0.4x

If x = 40

C'(40) = 40 - 0.4(40)

C'(40) = 40 - 16

C'(40) = 24

Hence the average cost per radio of producing the first 40 radios is 24radios

An 8 in by 8 in square air vent is shown where AG = 8 inches. BF is the midsegment of AADG and CEis the midsegment of ADBF. Which of the
following is measure of CE2

Answers

Answer:

2

Step-by-step explanation:

if BF is the mid-segment of the triangle ADG then its measure will be half of the measure of AG so 0.5*8=4 by the (mid-segment theorem)

then CE is the mid-segment of triangle BDF, so its measure is will be half of BF, so 0.5*4=2

Answer:

CE = 2

Step-by-step explanation:

The midsegment is half the length of the third side of the triangle, then

BF = [tex]\frac{1}{2}[/tex] × DG = [tex]\frac{1}{2}[/tex] × 8 = 4 , and

CE = [tex]\frac{1}{2}[/tex] × BF = [tex]\frac{1}{2}[/tex] × 4 = 2
