For each of the regions D in R^2 below, fill in the blank so that the statements are true:

A continuous function on D= {(x,y) ∈ R^2 | 2x^4+6y^2 >= 152} __________ have an absolute maximum.

a. must
b. might or might not
c. must not

Answer:

A - since the median can be any number we know of. B - Again the median can be any number we know of, since it is a undetermined amount. E - The range can be 10 flights, this is because it is not a determiend value, and it is possible for the value to be 10.

Step-by-step explanation:

Wrong answer reasoning:

The mode doesnt need to be 9 if there is more than 1 mode, so that isnt it. Eliminating D. The mean can most definatly be determinded if we know the values. This elimnates C. The mean can be 6.875, but we dont know, so we can assume it IS 6.875. This eliminates F.

Hope this helps!

Answer:

x  = 73

Step-by-step explanation:

A circle is 360 degrees

4x-5 + x = 360 degrees

5x - 5 = 360 degrees

5x = 365 degrees

Divide by 5

5x/5 = 365/5

x =73

Step-by-step explanation:

Given:

[tex]\frac{AD}{DC}=\frac{BE}{EC}[/tex]

To Prove:

AB║DE

Solution:

Since, corresponding sides of ΔACB and ΔDCE are proportional,

[tex]\frac{AD}{DC}=\frac{BE}{EC}[/tex]

Both the triangles will be similar.

ΔACB ~ ΔDCE [By SAS property of similarity]

Therefore, ∠1 ≅ 2 [CPCTC]

Since, ∠1 and ∠2 are the corresponding angles

Therefore, AB║DE [Converse of corresponding angles theorem]

Answer:

  x = 6.4

Step-by-step explanation:

The corresponding sides are proportional, so we have ...

  horizontal/vertical = x/(5+3) = 4/5

  x = 8(0.8) = 6.4 . . . . . . multiply by 8

Step-by-step explanation:

please I'm not sure for the numbers 3 and 2.

for number 10,

2/3x -4 = 3 +5

2/3x = 8+4

2/3x = 12

2x= 12 x 3

2x = 36

x = 18

and for number 4

(y+1)/5 - (y-2)/4 = -1

to clear out the fraction, multiply throughout by 20

after multiplying, we have

4(y+1) -5(y-2)= -20

4y+4-5y+10 =-20

14 -y = -20

-y = -20 + 14

-y = -6

y = 6

Step-by-step explanation:

Only graph in which x=2

Answer:

48

Step-by-step explanation:

180- 59- 52 = 69

Therefore,

69 + x + 63 = 180

x = 48

Thenks and mark me brainliest :)

Answer:

the answer is b=48

Step-by-step explanation:

52+y+59=180(angle on a straight line is 180)

collect like terms

y=180-59+52

y=180-111

y= 69

to look for x is equal to

69+x+63=180

collect like terms

x=180-69+63

x=180-132

x=48

so mark the briliest o

Answer:

The area of the rectangle is 4 sq yards.

Step-by-step explanation:

Given that,

The length of the rectangle, [tex]L=\dfrac{2}{13}\ yards[/tex]

The breadth of the rectangle, B = 26 yards

We need to find the area of the rectangle. The formula for the area of a rectangle is given by :

A = LB

Put all the values,

[tex]A=\dfrac{2}{13}\times 26\\\\A=2\times 2\\\\A=4\ yd^2[/tex]

So, the area of the rectangle is 4 sq yards.

Answer:

[tex]-\infty < y < -2[/tex]

Step-by-step explanation:

Given

The attached graph

Required

The range of the graph

From the graph we can see that the curve points down towards the y-axis,

This means that y starts from a [tex]-\infty[/tex] number

Coming up, the curve stops increasing at 2 and becomes horizontal; This means that y ends at 2

Hence, the range is: [tex]-\infty < y < -2[/tex]

Answer:

b = 20 cm.

Step-by-step explanation:

Define and explain:

This is a right triangle, so the Pythagorean Theorem applies.

The Pythagorean Theorem states that the sum of the squared legs will equal the squared length of the hypotenuse.

The legs of a triangle are the sides that form the right angle.

The hypotenuse is the longest side; the hypotenuse is always diagonal from the small square indicating a right angle.

Solve:

[tex]a^2+b^2=c^2[/tex]

[tex]a,b-legs[/tex]

[tex]c-hypotenuse[/tex]

[tex]15^2+b^2=25^2[/tex]

[tex]225+b^2=625[/tex]

[tex]625-225=400[/tex]

[tex]b^2=400[/tex]

[tex]b=20[/tex]

Conclude:

Therefore, the length of the unknown side is 20 centimeters.

Answer:

a. Area = 1,017.36 cm²; Circumference = 113.04 cm

b. Area

c. Circumference

Step-by-step explanation:

Given:

Radius (r) = 18 cm

π = 3.14

a. Area of the mirror = area of circle = πr²

Plug in the values

Area = 3.14*18²

Area = 1,017.36 cm²

Circumference = 2πr

Circumference = 2*3.14*18

Circumference = 113.04 cm

b. The area of the glass would be used in finding the amount of glass needed caused it's the surface of the glass that is to be replaced.

c. The silver wire would be placed around the mirror, therefore, it is the circumference that would be needed in finding the amount of wire needed since the circumference is the perimeter round the mirror.

Answer:

When we have a function f(x), the average rate of change in the interval (a, b) is:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

In this case, we have the function:

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

(but we do not have the interval, and I couldn't find the complete question online)

So if for example, we have the interval (2, 4)

The average rate of change will be:

[tex]r = \frac{(4 + 3)^2 - 2 - (2 + 3)^2 + 2}{4 - 2} = \frac{24}{2} = 12[/tex]

If instead, we want the rate of change in a differential dx around the value x, we need to differentiate the function (this is way more complex, so I will define some rules first).

Such that the rate of change, in this case, will be:

f'(x) = df/dx

For a function like:

g(x) = x^n + c

g'(x) = n*x^(n - 1)

And for:

h(x) = k( g(x))

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

So here we can write our function as:

f(x) = k(g(x)) = (x + 3)^2 - 2

where:

g(x) = x + 3

k(x) = x^2 - 2

Then:

f'(x) = 2*(x + 3)*1 = 2*x + 6

That is the rate of change as a function of x (but is not an "average" rate of change)
