Step-by-step explanation:

We can easily solve this problem by using a plotting tool or any graphing calculator.

We test each case, until we arrive to the correct option

Case 1

y ≤ 3x - 2 and 4x + y ≥2

Correct Option.

Which of the following would have the same graphic representation as the function f(x)=16(2)^x

Zinaida [17]

The options 2 and 4 would have the same graphical representation.

Step-by-step explanation:

Step 1:

To determine which functions are equal to the question, we must assign values to x and see which values equal the function f(x) = $16.2^{x}$ .

Any random value can be assigned to x but the same value of x must be assigned to all the equations.

Step 2:

If we substitute x = 5, we get

Question; f(x) = $16.2^{x} = 16.2^{5}= 16.(32) = 512.$

Option 1; f(x) $= 4.4^{x} = 4.4^{5} = 4.(1,024)= 4,096.$

Option 2; f(x) = $4.2^{x+2} = 4.2^{5+2} = 4.(128) = 512.$

Option 3; f(x) = $32^{x} = 32^{5} = 33,554,432.$

Option 4; f(x) $= \frac{1}{4}. 2^{x+6} = \frac{1}{4}. (2^{5+6}) =\frac{1}{4}. (2048) = 512.$

So options 2 and 4 would have the same graphical representation.

The city park department is planning to enclose a play area with fencing. One side of the area will be against an existing build

Oksanka [162]

Answer:

The maximum rectangular area will have the length 400 meters and width 200 meters with one side of the length against an existing building.

Step-by-step explanation:

From the given information;

The perimeter of a rectangle = 2 (L+B)

here;

L = the length of the side of the fence

B = the width of the fence

So; The perimeter of a rectangle = 2L+2B

we are also being told that;

One side of the area will be against an existing building

i.e

The perimeter of a rectangle is now = L + 2B = 800 meters

L = 800 - 2B

Similarly; Area of a rectangle = L × B

Area of a rectangle = ( 800 - 2B) × B

Area of a rectangle = 800B - 2B²

assuming A(B) to represent the Area;

Then the maximum area A'(B) = 0 ;

Thus,

A'(B) = 800 - 4B = 0

-4B = - 800

4B = 800

B = 200

Therefore; the maximum area have a width = 200 meters and a length 800 - 2(200) = 800 - 400 = 400 meters
